[M4F] Movie-night muscle memory gets you into trouble with your boyfriend's best friend

Arriving right on time for our weekend ritual of talking shit about awful movies, I'm a little surprised when Dave takes his sweet time opening the door. I'm even more surprised when it's you on the other side instead of him.

"Lemme guess, he bailed?" I ask with a snort, arching an expectant brow.

"Something came up back home, he flew out this morning," you reply sheepishly, as if your boyfriend's complete and utter lack of communication skills were somehow your fault.

"And he didn't think to tell me?" I add after a moment, glancing down at the beer I brought, as if were suddenly embarrassed to be holding it.

"I know, I know," you sigh. "You know how he is," you add, absently rubbing your arm. "He didn't even tell me until he was already packing a day bag," you continue with the hint of a laugh. "For a week's stay."

Idly glancing back toward my car, you stop me before I start to head back home.

"We can watch without him. I mean, if you want to. Just because he's not here doesn't mean the day is over, right?" you ask. I'm not quite sure if you're just being nice, but the hope lining your expression says you're just as eager to fight off boredom as I am. It wasn't like I hadn't already blocked out the afternoon as time to kill.

Soon we were settled on the couch with snacks and beer, and the day was unwinding well enough, some laughs had at some bad films. Most at their expense, but a couple genuinely funny moments crop up, much to my surprise. A few trips back and forth to the kitchen, and we settled into a good rhythm, but a few quiet moments overtook the scene when we had little to say. That's the thing about bad movies. Sometimes they're just boring instead of bad.

But sometimes you're surprised.

Like when your hand absently slips to my thigh, slowly raking your nails along the denim of my jeans. Too shocked to say anything, I watch with awe as your fingers seek my length beneath the fabric and slowly wake my length, greeting me with a good, slow rubdown. By now my heart's pounding in my chest, and I sure as hell don't know what to say. It's only after you've got a full handful of cock that either of us finds any words.

"Oh my god, I am so sorry," you suddenly gasp, yanking your hand clean out of my lap before diving to the other end of the couch. "Muscle memory. Oh my fucking god." Your face goes from white as a sheet to red as a beet in record time, a stream of apologies pouring through your lips. "I just— Dave. We. During movies—"

Bursting out laughing, most of the tension in the room melts away. Well, except the bit I'm sporting in those tented trousers.

"It's okay," I snort. "Easy mistake to make, I try to jerk him off all the time during these things," I add with a toothy smile, making you lose it with laughter, burying your head in a throw pillow to save a little face.

"I could die right now," I hear you murmur into the plush fabric. Before embarrassment claims your mortal soul, you get up and head to the other couch, flopping down a safe distance away.

The last few minutes of the film play out mostly uneventfully, but I can't resist the urge to tease you over your movie night muscle memory a bit.

"Oh my god, you're never going to let me live this down are you?" you adorably whine, before defiantly tossing a throw pillow at me.

"Tell you what," I tease with a wry little smirk, "I'll let you live it down when this goes down."

"Well, doesn't look like that's going to happen anytime soon," you reply without thinking, darkening another shade of red once you realize you're staring at and talking about another man's cock.

"I mean, it could," I grin, letting the implication hang in the air.

Your typical movie time habits backfire with a little accidental stimulation. Then some very apologetic, deliberate stimulation.

Some of the kinks I'm interested in for this scene include cheating, casual sex, barebacking, oral, handjobs, size difference, risky sex, semi-public, lingerie, and creampies.

Limits are non-con, abuse, bodily fluids that aren’t saliva or sexual, rimming, and darker themes. Despite the joke in the post, I'm also not into guys, even if you're playing female characters. Sorry!
