Part 5: So, You Must Be Grace

I only had one class left on Thursday, but I was finding it very hard to focus. I expect this would have been the case just from Tera reaching out again and the explicit caller ID picture she had set on my phone (which I couldn't help but pull up to look at a few times with my phone angled away from the other students). The ending of our conversation had me off balance even further however. I wasn't sure how I felt about Grace's reference to anal sex. The truth was I hadn't ever really thought much about it. I found myself reading the wikipedia page on anal sex, pulled up in a private window on my phone. "Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure." Well, sure. But why would a girl bring that up? Did it even feel good to them? I kept reading. "People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved through anal penetration – by indirect stimulation of the prostate in men, indirect stimulation of the clitoris or an area of the vagina (sometimes called the G-spot) in women, and other sensory nerves (especially the pudendal nerve)." Huh, the more you know. I closed the window and put the phone away. I was really putting the cart before the horse. I didn't know what Grace's agenda was, but I figured meeting her might be a good first step. The next 24 hours passed ever so slowly. I found myself pulling out my phone to look at Tera's picture whenever nobody was around to see, but didn't try to masturbate. Tera had seemed to like how much I came last time, I wanted to do it again if I could (if I got the chance). Finally, it was Friday night. I picked up some beers to bring along, and headed over to Tera's place, despite the fact that I would arrive almost half an hour early. I just couldn't sit still any more at home. I took an extra long, winding route to try to kill time, but was still pretty early when I got there. I was about to start doing laps around the block when I saw Tera's car parked in her spot. Guessing that meant she was back, I went up to the door and knocked. I heard some muffled rustling inside, and a voice said "Just a minute". I didn't think it was Tera, but I couldn't tell for sure. I was starting to wonder what was taking so long, and I shifted my box of beer to the other hand to knock again when the door opened. The woman who answered the door was definitely not Tera. She was shorter, probably only about 5'2", had tanned skin and vaguely Asiatic features. She was pretty, though not so much that you'd notice her in a crowd. She had long, straight black hair in a ponytail that ended at around the small of her back. I'm being a bit disingenuous by listing my descriptors in this order, however, as none of that is what I noticed first. The girl was CURVY. It was a warm day, and she was wearing a tight fitting white tank top that did not entirely cover the thick straps of the black bra she was wearing, which in turn barely seemed adequate to contain her very large breasts. She stood in the doorway, one hand on her hip, the other arm bracing against the door frame. When she spoke, her voice was low and sultry, like a woman in a smoky bar in a movie made in the forties. "Hello handsome, and who might you be?" I was a little stunned, having been expecting Tera and instead getting this woman who looked like a pin-up model from a low-end magazine. I checked the house number to my right to see if I had maybe knocked on the wrong door. No, this was right. "I'm, I mean, is Tera here?" I asked, thinking maybe this was Tera's roommate. She would have known I was coming though... "Tera who?" The sultry woman asked. Now I was really getting confused. I checked the house number one more time; still right. "She's dirty-blonde, about this tall, amazing boo... I mean bob. She has a bob. Haircut." I was so off-kilter, I had almost said something quite inappropriate for a stranger. The woman in the door didn't get offended, however, instead she burst out laughing. She doubled over, clutching her stomach as she laughed loudly. This afforded me a view right down her tank top. Her boobs were huge! They shook as she laughed longer than most people might have considered normal, then stood up again, now standing straight with both hands on her hips. "Whew... I'm sorry, I'm just fucking with you. Hi, I'm Grace, you must be the guy Tera won't shut up about." She held a hand out to shake, which I reciprocated. "Why don't you come inside and wait; she should be home soon." With that, she turned and walked back into the apartment. As we made our way over to the sitting area, I noticed Grace's sweatpants falling down slightly on her left side. She quickly pulled them up, but before she did I saw enough hip to know that either her underwear were riding insanely low, or she wasn't wearing any. What was this girl's deal? First, she makes Tera ask me about anal, then she pretends not to know who I am after answering the door barely dressed? She certainly wasn't what I'd been expecting. Grace sat down in the armchair, and I took a seat on the couch next to a T-shirt that I assumed was Grace's. "So," I asked nervously, "how do you know Tera?" "We had a class together last year. She was looking for a roommate as the year wound down, and we got along well enough so we decided to go in together. My roommate from last year was... not pleased with me, so I was glad to find a new place." "Your roommate and you didn't get along?" I asked, curious. "Yeah, but it wasn't my fault. Our place had terrible noise insulation. Plus, the upstairs neighbors always had their TV turned way up, even when we asked them to turn it down, so it wasn't all on me either." I wasn't entirely sure what she meant by that last part, but decided I'd pried enough already. I nodded as if to say I understood. "How about you? I know you met Tera while tutoring, how long have you been doing that?" She asked. "Oh, a couple years. It's a good job, mostly I only work with people who are serious about learning, so I don't have the problems corralling people who don't want to be there that actual teachers have to deal with." "And you have enough people interested? I had a friend who did that but couldn't seem to keep people coming. Maybe they just didn't like him though?" She mused. "I guess it's all word of mouth in a business like that?" "Yeah," I replied, getting more comfortable as the conversation went on, "I think my pupils have all liked me well enough, some of them were even recommend by friends I'd also worked with." "Yeah, Tera mentioned that you tasted good." Grace said, her voice getting husky again. "Oh that's good to... wait what?" I nearly choked as I mentally reviewed what I'd just heard. Grace responded quickly, the growling tone gone from her voice again. "She said she tested good; well, I suppose is the right word. She tested well after working with you." She smiled broadly at me. I was completely off center again. "Right, yeah she started doing much better..." I said lamely. I wasn't even really sure how to respond anymore, but luckily before the silence became awkward the door opened and Tera entered the room in a hurry. She addressed Grace first, who she could see from the doorway. "Hey Grace, I'm later than I'd have liked, but I think I've still got time for a shower. Would you neaten up a little before..." then she noticed me on the couch. "Oh, you're here early! Sorry I didn't beat you here, the game went long again." She walked over to the couch, giving me a quick peck on the cheek before continuing. "Well, I'll make it a really quick shower then and join you two." She noticed the shirt on the couch; she bent down to pick it up. "I guess it's just this really, thanks for not making too much of a mess Grace." As she picked up the shirt, I saw something pink underneath. I only caught a glimpse, but I was pretty sure I knew what it was. Tera dropped the shirt again, covering the oblong object, before turning to Grace, her face showing her annoyance. "Really?" She asked, clearly not pleased. Grace just shrugged. "I've been anxiously awaiting our guest today, I did get the rest of the place clean." She said, her face betraying nothing except in the eyes, which gleamed mischievously. Tera crossed her arms across her breast. "Well, then how about this, you finish in here while I go have that shower." She said. She grabbed my hand and pulled me up. "And you come with me instead, since I clearly can't leave you with Grace." I'd been putting two and two together; I was pretty sure that Grace had hastily hidden a dildo she'd been using when I knocked on the door. I was starting to wonder if she'd told the truth about why her last roommate had taken issue with her. In any case, I was excited at Tera's invitation, and quickly got to my feet beside her. "You're no fun!" Grace said as we made our way towards the bathroom.

"Oh, I'm loads of fun." Tera countered, and she slapped my butt, ushering me forward into the bathroom. As I passed the other two doors, I saw into Tera's room, which was neat and looked much as it had last time I was here, as much as I'd been able to see from the couch at least. The other door, which must have been Grace's, was closed, but was adorned with a large white street sign that proclaimed "Deliveries in Rear". I decided not to think about it, and just stepped into the bathroom. Tera stepped in behind me and closed the door, having to stand right up against me to do so in the small space. "Hi!" she said. "Please don't mind her, she just likes to stir up trouble. She's really a great roommate." She pulled her tank top up over her head, taking her sports bra with it. She'd been in the building for three minutes and I was already looking at her breasts, I wouldn't have complained if her roommate was Joseph Stalin. "Hel-lo!" I said, admiring her as she took a step back into the space the door had occupied. Her toned body was a delight to behold. I'd already noticed that she was considerably more tanned than when I'd last seen her. Now I could see an intricate pattern of tan lines that criss-crossed her torso. Judging by the pale areas, her swimsuit had looked more like a series of crossing straps than a conventional bikini top. I couldn't decide which was hotter, imagining her in her strappy suit, or admiring her in the nude with just the tan lines to remember it by. After she pulled down her shorts, standing completely naked in front of me, she held up her hands and twisted back and forth to show herself off. The criss-crossing pale lines went all the way down to her pussy, passing high over her hips and crossing low on her mons pubis, showing off a fair amount of tanned skin that ended just above her delicious-looking pink lips. I considered that the swimsuit was technically a one-peice, though it had certainly shown more skin than any bikini I was familiar with. I thought to myself I would love to see how she looked in it, and I told her as much. "Oh I'd be happy to show you, though I hope you're not disappointed I'm not wearing it right now?" Tera said with a smile. "Oh certainly not." I replied quickly. "Disappointment is probably the furthest thing from how I'm feeling right now." "Good to hear." Tera stepped past me, her breasts just brushing my shirt as she gave me another quick peck, on the lips this time, and turned on the shower. After waiting for it to heat up (we shared a quick laugh about how waiting for hot water was exactly the kind of thing that wouldn't happen in a porno), she stepped under the stream. She closed her eyes and let the water fall on her upturned face, pulling water through her hair with both hands. I stood admiring the water cascading down her curves until she moved her head out of the stream and asked, "Are you just going to stand there and let the floor get all wet, or are you going to come help me wash off? There's room for two in here." I don't think I'd ever stripped off my clothes so quickly. I stepped into the shower behind her, and she turned to face me as I pulled the curtain closed. She handed me a loofah and a bottle of soap, then held her arms up above her head. Smiling, I dropped the loofah and put some soap on my hands before going to work. After a couple of minutes, Tera spoke up. "You know, I think my breasts are clean enough now. Going to wash anything else?" I laughed. "Sorry, I really did mean to move on, I just couldn't seem to make myself. Can you blame me?" Tera laughed with me. "I suppose not." She replied as I finally did move my hands off her chest. I explored every inch I could reach, soaping her arms, her sides, and her hips and upper back. Her skin was soft and smooth, but the muscles underneath were firm. I marveled in the contrast. I think she washed her hair at some point, though I admit I was so captivated I barely noticed. She turned and I repeated my treatment for the rest of her back, stooping to wash her legs. I had to admit I wasn't sure if I should try to wash her crotch, I didn't really know if there was anything special I needed to do down there. I just used the same soap as everywhere else on myself, but I had an inkling it might be different for women. I awkwardly communicated my ignorance, and Tera gave me a reassuring smile. "Just give me a second" She said, grabbing a second pinker bottle. My cock had been hard pretty much since Tera had disrobed, and as I watched her work her hand on her pussy while the water dripped off her, my hand wandered over to my cock seeming of it's own accord and slowly started stroking it. Finishing her wash, Tera took notice of my masturbation. "Oh I'm sorry, I just realized you aren't even wet yet! Well, we can fix that." She said, lowering herself to her knees. The water passed over her head, striking my stomach and chest. "That's ok, I already had a shower today. Thanks thooooooOoh!" I half said, half moaned as she took my hard cock halfway into her mouth. "I see what you meant, yeah let's do that." Tera half chuckled around my dick in her mouth, then went to work. The last time we'd gotten together, Tera had teased the hell out me, licking me up and down and playing with my balls without actually taking my cock into her mouth more than a couple times, including when I finished down her throat. This time, she used an entirely different suite of techniques. She started by cupping the tip of my cock with her tongue, pushing her tongue forward and back to stimulate the underside while her upper lip rested on the top. Then she would close her lips with the last third of my member in her mouth, circling the head with her tongue. She'd alternate this with a just a gentle sucking, while her hands worked the rest of the shaft and cupped my balls. Every once in a while she'd take a break, laying my cock on her face while she took a few deep breaths, catching her breath and keeping me from getting too close to the edge. Before long she'd give me a smile and then go back at it. She was taking me further and further into her mouth, and I mused (later, I wasn't thinking about it at the time) that she was teasing me again, as she'd shown me last time that she was more than capable of taking me all the way down her throat with very little warm-up. As Tera worked her way further and further towards the base of the shaft, her teasing fell away and she moved faster, no longer taking breaks. It seemed like some more primitive part of her was taking over, and she skipped the last inch or so, grabbing me by the hips to force herself down the rest of the way at once. This triggered a similar response in me, and I put my hands on the back of her head, gently guiding it up and down. I made to pull her off after a minute to give her a chance to catch her breath, but she smacked my wrist and shook her head as much as she could, without ever opening her eyes. I thought I heard a muffled "uh-uh". She pulled me forward so that her nose was pressed against me again, and I did not argue. I held her head more firmly, pushing it forward and back so that only the last few centimeters of my shaft emerged from her lips. I would have been content to continue fucking her throat until I came down it just as I had that fateful night at the end of last term, but just then the curtain was ripped aside with an "Ah-ha!" Tera pulled herself back at the same moment my head whirled around. "So," Grace said, one hand on her hip and the other still clutching the shower curtain. "This is what's taking so long in here." She gave Tera a disapproving look. Realizing one of my hands was still on her head, I let it drop to my side, though I couldn't do anything about the massive erection. Tera tried to cover, though I'm not sure why. "I was just bending down to get this loofah!" She said, grabbing it and trying to get to her feet quickly. She slipped and fell back on her knees with an "Ouch!". Grace couldn't have looked less convinced. "Lady, I can tell the difference between water and your saliva all over his magnificent cock. Look, some of it's still dripping down your chin." Tera wiped her chin, looking sheepish. Grace continued. "I don't know why you care anyway; you're allowed to suck his cock all you like." Her pretended offense vanished, replaced by amusement. "I'm just miffed you didn't invite me to watch." Her shift in tone took me aback so much I nearly missed that she'd called my cock "magnificent". I knew it wasn't the biggest, but maybe it was true what they said, size isn't everything. Tera looked a bit thrown herself. "Grace, this is only the second time I've hooked up with him. I wasn't about to have you in here, just watching us!" She said affronted. I wasn't really sure what to say, if I'm being honest I was probably too stunned to say much anyway. "Who said anything about just watching?" Grace replied. "Tell you what, why don't you just carry on as you are while I give our guest a little show?" She pulled her tank top over her head, showing off her huge breasts in the relatively modest black bra she was wearing. Grace didn't have Tera's muscle tone, but there was no denying she was significantly more curvy than Tera. Tera looked up at me, her face unreadable. "How does that sound to you?" She asked. I was surprised that she seemed at all ready to go along with it. Between that and my surprise at Grace having burst into the room, I was still at a loss for words. I think I may have managed a "sure", while nodding a bit, looking back and forth between the half-naked Grace and the fully nude Tera kneeling in front of me. I think whatever part of my brain was working would have said yes to any plan that involved my penis in Tera's mouth. "See, he's down!" Grace said, gesturing one hand in my direction. Tera grumbled something about Grace's impatience, but returned her attention to my crotch. In my surprise I'd lost a bit of rigidity, and when Tera started up again she didn't pick up where she'd left off despite what Grace had said. She took the tip in one hand, pulling my cock slightly to the left, then started kissing the base and my scrotum on the side. She switched sides, then started focusing on the balls more, as I turned my attention to Grace. She had started... dancing was the only word. She undulated her body, running her hand up and down her sides while her hips rocked back and forth. She was slowly turning, and when her back was to me, her hands found the clasps of her bra. She tossed her hair back, then looking seductively over one shoulder, she undid all four, one at a time. Somewhere around this time Tera had started sucking on my balls much like she had during our first hook-up, though I wasn't quite so close to cumming this time. Grace had one hand clutched against her chest, while with the other she pushed the thick black strap of her bra off her shoulder. She moved her head to look over the other shoulder as she turned back to face me while pushing the second strap off. Now she was facing me, only the hand on her chest keeping the bra from falling to the floor. She bit her lip and then pulled it off and dropped it. Tera must have been watching as well, because I felt her let my balls out of her mouth and heard her mutter "show off" before taking the tip of my cock into her mouth again. Grace's breasts were quite different from Tera's. Tera's were good sized for her frame, if a little larger than average, and sat high and proud on her chest, jiggling when she moved in a way that left me hypnotized whether she was naked or fully clothed. Grace's on the other hand looked like genetics had given up on any sense of proportion. They were very large, with Grace's shorter stature making them seem even bigger on her small frame, and they hung down lower so that they didn't so much jiggle as swing like big beautiful pendulums as she continued rocking her body from side to side. She had large, flat areolas that were darker than the rest of her skin, and while her nipples were also on the larger and flatter side they were the same darker brown so they didn't really stand out the way Tera's did. Grace continued dancing and turning, her hands now working the drawstring on her sweats. Her back was to me once more when she pulled it loose, and as she was in profile again, she pushed her butt out while pulling on the front of her sweats to stretch them out, before letting them drop to the ground. I noticed a few things at once. I thought at first that I'd been wrong about her not wearing panties under the sweatpants, but then realized what I was seeing was the tan-line from a set of bikini bottoms. She had a darker tan than Tera, and I could plainly see where the cloth had sat, covering her modestly in the front but barely covering her butt cheeks at all. Suddenly I realized she had no other tan lines on her torso. I'd been so taken in by the size of her tits that I didn't realize they were uniformly tanned, Grace must have been topless for every tanning session. Nobody was paying it any attention, but water had been splashing all over the bathroom all this time. Tera was once again reaching the point of taking me all the way into her mouth and throat, and was leaning towards me to accomplish it. This left just enough room behind her for Grace to step in under the shower head, being short enough that the water passed right over her head, splashing against my front and the top of Tera's head. She pulled the curtain closed before speaking up again. "Well this is cozy." She said, as if we were all just standing around in a small room. She give me a mischievous look, putting a finger to her lips to denote silence before leaning forward to give me a kiss. I was more than a little surprised, and I pulled back. Tera noticed the water stopped hitting her as Grace blocked it, as well as my backward movement (all my movements thus far had been to push my cock further down her throat). She removed my penis from her mouth for the first time since Grace had started her striptease. "Hey now, what's going on up there?" She asked. She didn't sound angry, but I thought I might have detected a hint of jealousy. "Nothing!" I said quickly. "She kissed me!" I was more than a little confused. I didn't know the etiquette involved when your hook-up's roommate joined you in the shower. Tera smiled, her narrowed eyes relaxing. "I'm just kidding. If I wasn't prepared for Grace's antics, I wouldn't have left the door unlocked." She stood up slowly, pushing Grace back. "That said, if you're going to use your mouth, I wouldn't mind some of that treatment you gave me last time." I was feeling more than a little teased at that point, having basically been given two blowjobs without either one going to the end. I was still more than happy to be a team player though, and truth be told I had been hoping to have another chance to eat Tera out. "I'd be happy to!" I said, and Tera started to back up even further into Grace to give me room to kneel down before the latter spoke up. "Hang on! If you're going to be so quick to exclude me, at least switch spots so I can watch." I looked to Tera who shrugged before pressing herself against me. Her breasts squished against my chest, pushing the water out from between us. I could feel the heat coming off her, as the water wasn't exactly hot anymore by this point. She kissed me as we slowly switched places, ending up with Tera's back to the wall and me standing between the two girls. "Go get her stud!" Grace said, giving my ass a smack. "Oh, he's got a nice butt!" She said. "You would notice that." Tera said with a flat smirk as she pushed down on my shoulders. As I got down on my knees, She leaned back against the wall, spreading her legs as far as the shower would allow. Without a moment's hesitation, I pushed my head forward and began licking. It was definitely a different experience this time around. Last time Tera had been able to spread her legs as wide as she wanted, giving me better access to all parts of her vulva. In the cramped confines of the shower the best I could do was lick underneath and around her clit and lips. I thought back to how she had used different techniques as well when she'd been blowing me. The first time it was all about licking various parts of me, whereas today she'd focused more on suction and keeping me in her mouth. I tried the same thing, gently sucking on one lip or the other or her clit. Unsatisfied with how far my tongue could reach, I put one hand up between her legs, gently fondling her labia with two fingers. Looking up, I saw Tera had her head back, resting on the wall, and her eyes were closed, just like she had been under the water at the beginner of the shower. When my fingers grazed over the entrance to her vagina, she gave a soft moan, so I pushed one finger in carefully. Despite the water all around, she was less slick than I remembered. I had read about shower sex having a dryness issue before, so I wasn't surprised, just proceeded slowly and gently. Grace had been silent this entire time, and as she was behind me, I wasn't sure what she was doing, if anything. Suddenly, I could see her leaning over me in my peripheral vision, and looked up to see her kissing Tera passionately. This surprised me again, and I stopped sucking for a moment, though my finger continued its slow in and out pressure on her opening. "He looks pretty good at that," Grace muttered between kisses. She nibbled Tera's ear, then whispered something into it I couldn't make out over the sound of the falling water. I could hear Tera's reply though, her eyes were still closed and she didn't whisper. "No, he's better." She said. Grace kissed her again, then looked down at me for a while. "I mean, he's alright, for a guy." She said. I felt a bit affronted. Not only was she criticizing my head-giving skills, but those of my entire gender! I had no choice to make a real showing. I craned my neck so I could get more of my mouth on Tera's pussy. It was a little uncomfortable, but I was the giver here, not the receiver, my comfort didn't matter so much. I lapped along her inner thighs, then spread my tongue wide and dragged it across her pussy. I pulled out every trick I'd ever heard, and even invented some new ones, keeping those that got a response from Tera and stopping ones that didn't. I circled her clit with my tongue, I poked it into her vagina, I even put one of her legs on my shoulder so I could get even better access, sucking and licking her clit while putting two fingers inside her. Grace took notice. "Ok, maybe he's got some skills. But I won't know for sure until I try him out myself." Tera didn't seem to acknowledge Grace's comment at first, but I hesitated a little. This seemed like it crossed a new line; Grace watching us was one thing but nobody had said anything about me and her having sex. I mean, I would happily do so, but not at the expense of angering Tera. Perhaps noticing my pace slacken, Tera said "Wait your turn" without opening her eyes. That hadn't been the response I expected. I renewed my oral assault on her pussy. Grace was quite for a minute, then spoke again. "Come on, you know I'm not good at waiting. Remember Mexico?" I was a bit curious. I'd never got the sense that Tera was into her roommate, or even girls in general, but she had kissed her. "Not a chance, I'm enjoying myself." Tera said. Grace waited only about ten seconds this time before continuing, her voice sounding more urgent. "Remember the third night? I'll do that again." Tera didn't respond, and I saw Grace lean forward again. Taking a moment to catch my breath, I looked up and saw her kissing Tera's neck. Between kisses she said "Twice." Tera finally opened her eyes, looking slightly annoyed but also hungry. She pushed Grace back with a hand on her chest, but said "Three times. Whenever I ask!" Grace gave a fist pump and a "Yes!". Tera looked down at me and said, "We will finish this another time when we have the shower to ourselves, I promise." Then motioned for me to turn around. Despite my feelings about being down to fuck Grace, I wasn't about to just jump in that quickly. Besides, my curiosity was more than piqued. "What happened in Mexico?" I asked, still kneeling in front of Tera as she stood up normally. She suddenly looked shy, which surprised me given she had basically just agreed to turn this little shower escapade into a full on threesome. "Well, so I'd never been interested in a girl before, but Grace was there and we were sharing a room... and she had those tits out all the time... I mean look at them!" She reached past me and I couldn't help but follow her with my gaze. She grabbed one of Grace's breasts, squeezing it softly. It was much larger than her hand could grip, but she hefted it up slightly. It looked soft, and though she was standing out of the shower's spray Grace was coated with a thin sheen of water droplets which occasionally ran down her body, further accentuating her curvature. "She jumped in the shower with me the second day 'just to save time', actually a lot like this. And well, I'd never felt that way before." Grace laughed. "That's a long way of saying I fucked you so good I made you bi!" Tera's hand withdrew, and I looked back at her. "You did not make me bi, you just.... helped me figure that out." Tera said lamely. She smiled at me awkwardly. "Look, I'll tell you the whole story later, just eat her out so she'll let us move on." I must have still looked a little hesitant because she gave me a corny thumbs up then started pushing my shoulders around. Maybe kneeling between two naked women made me feel a little submissive, but in any case I didn't put up any more fight. I turned towards Grace, and was surprised to see she was turning around as well. "I prefer it from the back!" She said, smiling over her should as she faced the wall. "Actually I prefer most things from the back." I heard her say as she placed her hands up against the wall and spread her legs. Her pussy was fully on display, her lips more pronounced and darker than Tera's in accordance with her darker skin. To my surprise, there was a large round jewel covering her anus. I knew enough to guess it was a butt plug, but had never actually seen one, much less this close. As I stared at it, Tera spoke from over my shoulder. "Wow, this is exactly like in Mexico, huh? Did you do that on purpose?" She asked Grace.
"Total coincidence actually, though I guess given how often I wear these it wasn't that unlikely." Grace said candidly. I guessed it was pretty obvious why Grace had made Tera ask me about anal, and I assumed it wasn't her first foray. It was mine though, so though I had grabbed onto Grace's hips I was still staring when she turned over her shoulder and spoke again. "It's not going to bite you, show me what you've got!" She pushed her hips back, closing the distance between her pussy and my face. "Well, it's not like it's in the way of her pussy," I thought to myself, "and at least my nose won't be right in her ass." I'd had that issue when I tried eating a previous girlfriend out from behind once, and it had not made the session sexier. Maybe some guys were into that, but I for one had not been. I had to adjust for her clit being lower and further away from me, especially since Grace was shorter than Tera, but she compensated for it by being able to bend over forward. She arched her back hard, which stuck her pussy out nicely. I should probably have started with more foreplay, but remembering that she had been pre-gaming when I arrived at the house I dove right into Grace's pussy. I quickly realized I could use my usual techniques, they just hit her clitoris before her vagina instead of the other way around. It was harder to get good suction on her clit, but on the other hand I was able to stick my tongue even further into her vagina than I would be able to otherwise, though when I went ham at that I ended up bumping my nose on her plug, which surprised me more than a little. Grace almost immediately started making all manner of moans and gasps. She was clearly much more vocal than Tera, or indeed any other girl I'd ever been with. I remember thinking for a moment that it seemed somewhat performative, but whether it was being accentuated or not it made it easy to tell what she liked best and it was pretty hot besides. I quickly realized that Grace liked her clit played with more than her vagina, and she was especially loud when I spread her ass with my hands. I tried doing both at once, and was rewarded with her loudest cry yet. "Oh YEAH! He does know what he's doing." I glanced up as she looked over her shoulder, not at me but at Tera. "Do you remember how to take this thing out?" Tera leaned forward, a look of concentration on her face. She carefully took hold of the plug with her thumb and first two fingers and began to pull as I watched with fascination. Behind the jewel the plug was quite narrow, though the angle Tera was pulling at opened Grace's anus slightly. As it came out, the plug thickened significantly, stretching Grace's hole wider and wider. As she reached a level of stretch I wouldn't have thought possible, Grace gave a loud moan and then suddenly the plug popped out in Tera's hand. She quickly withdrew, and at the same time Tera's hole closed itself again. I had never had any interest in anal anything, but watching Grace's asshole flex and constrict, I wondered if perhaps that was where the interest lay. It glistened slightly with what I assumed was lube; what I had read online was that lube was crucial for anything involving the ass. Tera bent down to whisper in my ear, breaking me out of my stunned examination of Grace's sphincter. "Don't stop now, if she asked me to take out her plug she's getting close." I resumed my licking and spreading, a bit worried that with the plug removed I would be putting my nose right in a smelly area but to my surprise there was no smell. Actually, I realized there was a slightly fruity aroma I guessed was strawberry. Later, I guessed it was the lube Grace was using, but at the time I was more than distracted. Tera continued whispering in my ear, while Grace continued her moaning. "Make her feel good now, and she will pay you back double, I assure you." She said, sounding as if she spoke from experience. "Give her ass a smack and keep spreading it, she loves that." I did as I was bid, alternating sucking and licking her clit while I used both hands to slap, jiggle, massage, and spread Grace's ass. Her volume built and built, until eventually her breath was coming in pants, and she was chanting "Yes, yes, Yes, YES, YES!". Sensing she was close to finishing, I sucked even harder at her clit, spreading her ass as wide as I could. Her vagina and anus were both gaping open in my face now, and Tera whispered once more in my ear. "Good! She's practically there. Now finger her vag and lick her butt hole!" Had someone told me to do that under almost any circumstances, I would have looked at them sideways and backed away. This was Tera however, and I'd been following her commands since she arrived in the apartment, and I wasn't going to stop now. Without thinking, I put my thumb in Grace's vagina, using my first two fingers to tickle her clit, while my other hand spread her ass wide enough to plunge my tongue into her anus. It didn't feel that different from tonguing Tera's vagina had, and surprisingly, there was the strawberry taste again. I didn't really notice right then however, as Grace let out a bellowing "YEEESSSSS!". Her legs stiffened, then started to shake around the knees. I felt her anus contract, pushing out my tongue, while her vagina pulsed on my thumb. Leaning back, I watched as her anus opened and closed about once a second, in rhythm with the squeezing on my thumb. Now I was really starting to see the appeal. As Grace stopped vibrating I slowly withdrew my hand. I stood up and Grace turned around to face me, putting her arms around my neck and resting her forehead on my chest. "Ok, that was pretty great." She said, catching her breath. "Would anybody object to getting out of the shower now? The water is freezing." Without waiting for an answer, she steeped out of the shower, picked up a towel, and started drying off. After a quick shared look, Tera and I did the same. I was just finishing drying my hair when I felt something on my still quite-hard dick. Removing the towel, I saw that Grace had hung hers on me. "He does work as a towel rack!" She said, doing a sort of doubled-over double fist pump. I quickly removed the towel, and Grace opened the door and stepped out, opening the door to her room and stepping in. I looked to Tera, but she just made a motion gesturing me out of the bathroom. "Well, what are you waiting for? I haven't cum yet either remember? Let's keep it going." Needless to say, I went.
