⚜️ FIONA - little sister, great love? [CHAPTER 7/16] ⚜️ [Stepsister] [Freeuse] [Group Sex] [Jealousy]

NSFWFreeuse

Good morning everyone,

I have to warn you today: This chapter wrecked me—literally. I started writing it several times and had to start over again and again because it was incredibly hard for me to put these emotions into words.

By now, this is no longer just a story for me! Writing it hit very close to home. At the very least, I empathize with Fiona now. What you are about to read is perhaps the most intense piece of character development so far. Be gentle with me and with Fiona.

By

Enjoy reading, your LIEBH4BER.

"All I know is: I like you! You turn my head, but you're allowed to..." I sing loudly along with the radio and shake my hips to the beat. Right now, I'm just doing great! I have excellent grades and the best thing: I have you! I'm currently preparing popcorn in the microwave. Again, I have this warm feeling in my chest. It just feels fantastic. It's Saturday evening, shortly after nine. The house is empty; our parents are out again. They need their couple time too! Today I was out with Mia all day. By now we meet every day! We get along very well. Today we went for coffee first and then went for a little walk. Now we are both at our place and want to have a little movie night. Who knows what else might happen.

You are upstairs in your room gaming with your boys. I don't think you noticed that we are both here in the living room. I brought Mia along because I knew you didn't have anything planned for tonight. Maybe you have time for us? You haven't seen each other since last weekend. She asked about you a few times. I don't know yet how I feel about that. I hear you upstairs, your loud laughter with your boys over Discord. Nice that you are doing well too. I notice that apart from our agreement, we do very little together. "But we only agreed on FreeUse, right?" I ask you, even though you aren't even here. Mia is sitting on our couch. Exactly at the place where we introduced her to our forbidden world. Today, however, she is like a different person. She is wearing a pretty sweater and leggings. Little is left of the shy girl who hid under the blanket. She sometimes looks towards the stairs. Is she waiting for you to come? Does she think you would come because of her? Dream on, girl! I think to myself and laugh inside. If anything, you come down because of me.

Mia's cheeks are slightly flushed. She seems excited about something—or someone. Even if she doesn't show it, I see her pressing her legs together. She can barely sit still! She wants it to happen again. She wants to see us in action again! She wants to enter that atmosphere again where everything was possible last week. No taboos! Only total trust and lust! But she would never ask. Never. That's not Mia's style. But she would let it happen immediately. And again, I only think of you and what you always do to me. I feel it myself between my legs—this hot, throbbing tingling. It never gets less!

"So Mia? Do you think we should go upstairs and check if everything is okay with him before we start our movie night?" I finally ask. Neither Mia nor I can wait any longer. We both can't wait for you anymore. Mia gives me no answer but jumps up in a fraction of a second and is ready to visit you upstairs in your room. I am completely perplexed! She seems to want you just as much as I do. I absolutely don't like that at all! I'm probably making a very puzzled face right now. "Yes, Fiona... I mean, sure, if you want," she says embarrassed and tries to sit down again. I caught you, you slut, shoots through my head! "Well then let's go up quickly. But I have to get something from my room, okay?" I ask her and point to the stairs with a nod. She starts moving slowly and taking the first steps. She has her arms locked in front of her body as if she had to hold on to someone. She is so nervous! How cute she is, I think to myself and can't suppress a grin. We arrive in front of my room. I signal Mia to wait briefly in the hallway. I scurry into my room and get my black sleep mask from my nightstand. I close the door silently and grin at Mia. She understands immediately. I also notice how I start to tremble. It is always this anticipation! You drive us both crazy and probably don't even notice it. Mia can't take it anymore and quietly opens your door. We open the door fully and both look at you. We both have very big eyes and focus on you as if we were predators and you were our prey.

Then you see us. I don't know if you realize what's coming to you. "Hey Fiona and Mia," you say casually and just keep gaming. You ignore us brutally. But then I see a very small grin in the corner of your mouth. Gotcha! I think to myself. What satisfaction. "Yo, that's just my annoying sister and her friend. No idea what they want again," you snort into the microphone while looking us both in the eyes. Your buddies seem to laugh with you because you immediately start joining their chorus. Mia lets her shoulders drop immediately and looks hurt. You can't do that to her; she's not ready yet. I notice she wants to put it in reverse. I just put my hand briefly on her shoulder. She looks at me uncertainly immediately. I simply shake my head. "We'll pay you back for that in a second, idiot," I retort and wave my sleep mask in my right hand. It overcomes you. I feel that immediately. "Yeah, boys, they have some problem again that they need the most handsome man in the house for," you show off in front of your friends. "I'll be right back. Go ahead and play a few rounds without me," you add and turn off your microphone.

With my mask, I just point to your bed. You understand immediately. My look is dark by now. You have awakened a monster in me. "Mia, that... that was just a joke. I'm sorry if I hurt you," you say to her when you see her sad face. "You better watch out that we don't hurt you in a second," she hisses back at you. She starts to grin. That knocks me completely off track. I never expected such a tough reaction from Mia in my life! "Chapeau!" I whisper to her. "Strip! You handsomest man of the house. But make it snappy!" I instruct you. "A different wind is blowing here from now on, right Mia!" I ask into the room. You take off your shirt and pants, lie down on your back on the bed. This situation is completely new for you too. Now we dominate you. You have no power here anymore! Mia nods. I sit on the edge of the bed, stroke your cheek once, then pull the mask over your eyes. "If you take this mask off, we're gone immediately. And by the looks of it, you really like that we're here!" I say and stroke your big bulge. You flinch immediately and obey. You say no more words. You trust me blindly. I just know that. I stand up again, turn around. Mia is still standing at the door, eyes huge. Huge with horniness. I pull the hoodie over my head, let it fall. I open my bra and take off my sweatpants. Now I'm standing in front of her only in my white panties. I can see you trying to see something through the mask. But you don't succeed. You are completely at our mercy.

Mia is back in this world too. This world she was allowed to taste a bit of last week. Today she wants more. I feel it. It arouses me even more. At the same time, it scares me. What if she develops feelings for you too? Then I have to end our relationship. Sharing you physically is hard, but okay. But emotionally, no one gets you! Mia has undressed completely naked right away. She is completely shaved this time too. Not a single hair can be seen on her. "We brought you a game today!" I say, my voice rough. "You have to guess who is spoiling you right now," I whisper to you. It overcomes me. This hot feeling. This feeling of control! My vision goes black for a moment. My whole body trembles, overreacts. But you don't seem to fare any differently. Your heart beats wildly, even though we aren't even touching you yet. You are breathing very irregularly already. You don't know where to put your hands either! I take off my panties and drop them to the floor.

I pull Mia onto your bed with me. Now we are both sitting, completely naked, me to your right and Mia to your left on your bed. I come towards you, kiss you first—very slowly, deep. I am completely in this moment right now. I enjoy every second. You moan softly, your grin gets wider. I pull away from your lips. Then I nod to Mia. I am curious what she will do, how far she goes. It is a test for her. How far does she want to dare into this world? I don't believe my eyes! I would have thought she might give you a kiss on the cheek. But she too leans forward, kisses you hesitantly, feather-light. Directly on the lips. You freeze immediately and laugh embarrassed. You don't know how to react. "The first one was you of course Fiona... and... and and... I wouldn't have thought Mia would dare," you stutter. With that, Mia has awakened the beast in me. I'm sorry, but now I have to prove to her how much you belong only to me! I watch Mia kissing you, how her long blonde hair falls into your face, just like mine used to. How she closes her eyes before she touches you, just like me. How she breathes, fast, excited, insecure, just like I did back then. And suddenly there is no "you, me and Mia" anymore. There is only you, me and a second Fiona. That becomes clear to me right now. It shoots into my head immediately. You get along so well with Mia because she is just like you, dummy! I say to myself and smack my forehead. I simply brought a still inexperienced and shy version of myself into the game!

"An earlier version of myself," I have to admit to myself! I am jealous of myself! it screams inside me. Of this pure, unused, shy Fiona that you are currently rediscovering in Mia. I swallow hard. My hands tremble slightly. Mia kisses you deeper, her small hand lays on your cheek, exactly as I always do. I can't take it anymore. I lean forward, kiss you next to her mouth, our lips almost touching. I taste you. I taste her on you. No, I taste myself! You try to breathe in between and put your arms around both of us. Mia is beaming all over her face. She is beaming at me too. I have to smile too. A mirror is being held up to me right now. How can I be mad at my old self? I was in seventh heaven in the beginning too! I too couldn't think of anything else but our first kiss. And at the same time, it hurts so damn much! It tears me apart.

I take your hand instead and guide it between my legs. I show you how wet I am—so wet that your fingers glisten immediately. You find my clit right away. By now you know my body better than I do. I notice that you are spoiling Mia at the same time. She gets the same treatment as me. I close my eyes and moan softly. Then I tap Mia carefully. She opens her eyes immediately. I point with my head to your bulge. She nods. We both pull back from you and kneel next to your legs. Mia pulls off your boxers. Immediately we see your hard cock. The head is already wet and glistening. Immediately I take your cock deep into my mouth and suck you like I never have before. I think I desperately want to prove to you that I am better than Mia. That you need me and not her. Then I stop again and Mia takes over immediately. She grips your shaft and licks from your balls to your head first. Then she encloses your cock immediately. She tries something completely new! She doesn't move her head anymore. She spoils you only with her tongue. Like wild, she circles your head. "You both do that so well! I think I'm the luckiest man in the world right now!" you try to say without moaning.

I let Mia spoil you a little longer. I let go of you and come towards your head. You try to turn your head to me. You probably think I'm coming to kiss you. Wrong thought! I grin darkly. I place my knees next to your head and immediately hover with my pussy over your face. I lower myself—very slowly, inch by inch—until your tongue finally touches me. The first contact is like an electric shock. You know your mission and lick me relentlessly. It makes me incredibly horny. You lick me to orgasm and at the same time our little Mia sucks you off. The jealousy is suddenly gone. Before I come, you stop and call: "Mia, careful! You have to stop!" I turn around and she looks at me with wide eyes. I just nod to her and turn back to you. I try to press my pelvis even more into your mouth. I claw into your hair! Then I feel it rising in me. I ride your face, circle, press myself harder onto you until your nose rubs against my clit, until you can barely breathe from lust. My hips move as if by themselves, faster, harder, I hear myself moaning, loud, animalistic, unmuffled. I come so hard my legs buckle. The waves race through my body. I can only tremble and gasp your name. I can barely hold myself on you. But I feel the twitches in your body. You are cumming right now too. But for the first time, it is no longer my mouth. You cum inside the new Fiona. I try to block that out. I accept it!

I need a second, maybe ten, to come to my senses again. My thighs burn, my heart races, I am wet with sweat. Slowly I slide off your face again. "Now it's your turn," I let you understand. I get a condom from your hiding place. By now you have to buy a pack several times a week. Mia lets go of you too. Licks you clean once more and then sits down next to you again for now. She waits for an instruction. I like that. Very slowly I open the condom pack and roll the condom over you. Right after that, I place myself over you. Your head is right at my entrance. I lower myself slowly, enjoying every moment. I take you very deep. Let you slide very deep into me, to the hilt. Then I just sit for a moment. Mia holds her hand over her mouth. For her, it must be the hottest thing she has done. "Well, does he taste good?" I ask her laughing. "Yeeees..." she could only breathe.

I feel you pulsing inside me, feel every little movement, every twitch. I breathe heavily and go inside myself. Mia is not yet ready for your cock. I simply don't want that yet. But we can't just leave her sitting here like this now. You beat me to it and say: "Mia, if you want I... I would have a seat for you here!" you say embarrassed. I need a short moment to collect myself, to feel you completely, to know that despite everything, despite Mia, despite everything that just happened, you still belong to me. My hands lie on your chest, I feel your heartbeat under my fingers. Mia is like remote-controlled. She comes slowly towards your face. I watch her very closely. She sits down backwards on your face. She sits exactly opposite me now. She looks me in the eyes. Immediately you find her clit and lick her. That is my sign. In this moment I start to move too. First very slowly. The situation overcomes me. I can't help it! Mia belongs more than just to it now. I take her face between my hands and kiss her. Just like I would kiss you. Hot! With tongue! While I ride you and you lick her clit. We are the perfect symbiosis. We are the perfect harmony!

Mia moans into my mouth. I feel that she is almost there. I also feel you getting harder inside me. I ride you faster, move my hips even faster. I start to almost drive you crazy by letting you slide almost completely out of me again and again, only to feel you immediately to the hilt again in the next moment. In this moment Mia throws her head back. She screams out loud and claws into my arms. You too cum hard inside me and pump your seed into me. I cum too, but I don't give myself over to my orgasm this time. I try to keep my eyes open. Despite shaking wildly and barely being able to control myself during my orgasm, I want to watch Mia very closely. I want to see exactly what is going on inside her. Just to be safe.

When we three have calmed down again, I pull back from you. Mia gets up from her new favorite seat too. I pull off your condom and knot it together. "It's not my fault that I'm dirty again, but you guys would have to clean me up again now!" you instruct us. We both kneel in front of you, lick you clean, alternately, in perfect harmony. After you are clean again, we both cuddle up to you again. You pull the blanket over us three. I lay down on your neck as usual and give you occasional kisses. Mia is still completely exhausted and can hardly believe her luck. I simply lay her head on your chest. "Thank you! Thank you that I can be part of this. That you allowed me this. I am so happy!" she breathes directed at both of us. Shit! I think to myself. It happened. Now there is no FreeUse without Mia anymore. A small tear rolls down my cheek. I wipe it away immediately.

And I can't hate Mia—she is me! I can only love her. I can't resent her for anything. I am her! That deals me the final blow. I am so happy that I built something so beautiful with you. At the same time so infinitely sad because I fear that I am no longer sitting alone on the throne. You are only giving her what I wanted back then. I close my eyes and just hope for the best! Three bodies. One heartbeat. I let her in too far. There is no turning back anymore.

And I don't know if I regret this or if it is the most beautiful thing that could ever happen to us.

"Damn it!" I just scream in my head...
