My sisters best friend [M/F]

You must not know I’m here. You wouldn’t, you were already in bed by the time I got showed up. I had too much to drink and my sister let me crash at her place, but evidently forgot to tell her best friend who lived with her. My sister had left hours ago for work, leaving me snoozing in the living room while you still slept in. You’re not asleep anymore.

I can hear the buzz of your toy and gentle moans from just down the hallway. My morning wood stiffens further, leaking precum as I stroke myself while listening to you masturbate. I push my luck and creep quietly off of the couch, my hard cock pushing my boxers out. I slowly peek through the cracked door into your bedroom and can see your bare calves outstretched on your lavender sheets, your toes curled with pleasure. I lean further, seeing your hands playing with yourself. You rub a small vibrator against your clit while your other hand dips fingers in and out of your pink slit. You have a neatly trimmed bush above your smooth shaven pussy, turning me on even more.

I have my dick out now, jerking off watching you get off. I take in your dot body with my eyes and ears, hearing your wet noises and quiet moans. You gasp suddenly and the sound of your laptop slamming shut clicks as you cross your legs.

“Who’s out there?!” I can hear the panic in your voice. I say my name and apologize for scaring you. “Did you… see…?” Your panic changes to shame as you recognize my voice.

“I uh, I might have seen,” I admit with equal shame. There’s a long pause before either of us speaks again.

“Did… did you want to…?” You ask, feeling out the situation and that burning horniness returning. I laugh and don’t really respond. “I’m guessing you have been?” You accuse me, not sounding angry really, just exposed. I again dodge the question and ask if you minded. “Only if I get to watch you.” Your voice shakes at your own boldness. I walk into your room, my erection still in my hand as I grin at you, both of our faces cherry red. “Yeah, that’s what I thought you were doing out there,” you giggle, your eyes darting from mine to my cock.

“Mind if I sit?” I ask, gesturing towards your bed. You nod and watch as I strip so that we’re both naked. You never covered your chest so I had been staring at them pretty much since I walked in. You always wore low cut tops, showing off your perky cleavage, but they never looked half as good as they do now. Plump, firm, your pale nips hard on them as a bead of sweat runs between your perfect tits. I sit across from you, stroking myself as I imagine how they’d feel around my dick while I tittie fucked you.

You hesitate to spread your legs, self conscious with the view I’ll have of your most intimate parts. Watching me jerk off to you makes it unbearable for you to not to touching yourself though and you finally spread your legs towards me, showing me your delicate pink folds as you go back to using the vibe and fingering yourself. We both laugh a little at the ridiculousness of it whenever our eyes meet.

“You have to do something for me since I caught you peeping.” You slyly say to me. I hesitantly agree, not really caring what it is so long as I get to keep watching you playing with yourself. “I want you to cum on me.” You say shakily, the idea alone making you shiver. I agree, surprised, but very willing. “Wherever you want, so long as it’s not in my eye.” You laugh, further relieving the slight tension still between us. I let you know it’ll be a surprise, but really it’s just because I haven’t decided yet.

I drink your body in with my eyes, your beautiful eyes watching me jerk off to you, your chest rising and falling with uneven breathes. Your hair clings to your sweaty skin, draped over your shoulders and laying around your breasts. Your lightly shaded nips are hard and sensitive, poking up and begging to be touched. Your forearms cross your stomach, reaching between your sexy thighs to touch yourself, soaking your fingers in your sweetly scented wet. Fuck you’re gorgeous.

Your eyes widen in excitement, pupils dilated as I move next to you, getting on my knees and stroking myself faster. You know what’s coming, the shaking in your thighs gives you away. I put a knee on either side of you and groan as I blow my load all over you, spraying you with my hot jizz from your navel to your tits. You moan loudly, climaxing just after me as you feel yourself being cummed on. We both laugh a little as we make eye contact again, suddenly realizing how horny we both were to invite the other to watch. I get up and stand beside the bed, pulling tissues from the box on your nightstand for you to clean yourself up with. You play in it for a few seconds before wiping yourself off.

“Can you keep a secret?” You ask me, head tilted in a flirtatious way. I nod my head in agreement with a smile, curious. “Your sister made me promise not to fuck you when I moved in,” you admit.

“Well, we haven’t fucked,” I chuckle. “I mean technically.” I shrug my shoulders, letting you reach out and grab my half stiff cock.

“But you’re going to… right?” You half demand, half beg. My shaft twitches in your palm, returning to its full thickness as I think about all of the ways I’m going to fuck you and violate your body. I get back on the bed and lay next to you, meeting your kiss as we both pant, overwhelmed by our aching need to feel the others hands on our bodies. I run my fingers across the soft patch of hair above your slit and go right to finger fucking you. You moan into my mouth as I feel your warmth and wetness running down my hand.

“Ooohhhh!” You exclaim, the noise involuntary as I move my fingertips to the small area between your pussy and your asshole, teasing at it. You squirm, unable to control your breathing. I move further, toying with your rear before penetrating it with my middle finger. You cry out, jerking me off more quickly. I slide my knuckle in and out of you for a few minutes, keeping you moaning. You push my hand away suddenly, throwing yourself on top of me.

“I need to feel you in me, right now.” You pant, guiding the tip of my dick between your pink lips and sinking down onto me, your pussy tightly stretched around me, warm and slick with your delicious creamy wet. “Your big cock feels so good,” you moan, enjoying the feeling. “You’re too big to fuck me in the ass, I’m sorry,” you apologize. “But I’ve never played with my asshole before, that was amazing.” You sit on me, my dick fully inside of you and pressing up against your cervix as you talk to me while your body relaxes enough to take me without as much pain and effort.

“It’s ok, your pussy is so tight I don’t think I’ll mind not fucking you from behind.” I move hair from your face as I reassure you, turning you on even more.

“You better fuck me from behind, just not in that hole.” You request, moving your hips now. Slow, purposeful grinding on me makes sure that every inch of my cock can feel your vag gripping me. You start moving up and down, leaning back both to put pressure on the front wall of your pussy and give me a view of your grooly labia wrapped around my shaft as you take it in deep and then pull up so only my tip is still inside of you before sinking back down. We both moan in pleasure from the tight fit of our bodies as we fuck lustfully.

I press my palm to your stomach, feeling your insides move as my dick stretches you. My thumb finds your clit and runs it, drawing a loud moan from you. You move your body faster, bouncing on me now and breathing hard. I keep pausing from playing with your bean, keeping you edging for what feels like eternity for you before I finally rub you more quickly, making you cry out. You arch your back and moan as you climax, softly saying my name as you shake on me, slowing your pace until you’re stopped. You roll off of me and sound surprised when I get on top of you, pulling your leg up in the crook of my arm as I ram my hard crack back between your still spasming labia and into the warmth of your body.

“Don’t cum in me,” you beg. “Please don’t cum in my pussy.” Your eyes are looking deep into mine as you plead with me to not creampie you. “You can cum on my, ohhh fuck,” you try to piece together a sentence. “You can cum on my face for all I care, just not in my pussy.” You offer. I agree, still pounding my long shaft deep inside of you. Your already sore before I pull out of you and flip you over, pulling you by your ankles to the edge on the bed where you plant your toes on the hardwood floors and lift your ass, presenting your holes to me.

You cry out as my hand smacks your ass cheek, making you even more wet. I thrust my cock back into your pussy, holding your waist as I fuck you bent over. I tease and finger your asshole again, making you cum hard almost immediately. It’s so hard not to bust inside of you when you cum around me, your pussy massaging my dick as it brutally bottoms you out. I’m nearly there when you climax again, tempting me to put a baby inside of you. I pull out and pick you up, still shaking as you orgasm.

I toss you onto your back in the middle of the bed, getting on top of you and putting my wet and grooly cock between your perfect tits. You understand what I’m wanting and push your boobs together around my dick, moaning as I tittie fuck you. You tilt your head down and take the tip of my cock in your mouth, sucking on it until I thrust further forward and groan as I gush hot cum in your mouth, surprising you. My hand is on your head, forcing you to take my whole load. You swallow it and gasp as I release my hold on you.

“Fuck you cum a lot!” You exclaim, spit and my jizz still running from the corners of your mouth. “I wasn’t expecting that.” You laugh, now slowly stroking my cock. “Help me get cleaned up and make breakfast?” You ask. I agree with a smile. “Good, your sister works til four today, fuck and make each other cum until 3:30?” You kiss the tip of my dick, feeling your pussy aching from getting fucked, but aching worse to feel me stuffing you again.
