Interrupting a sleepover [F18/M20/F18]

This story is 100% true and happened to me when I was in college. A couple of my previous stories are below: https://www.reddit.com/r/gonewildstories/comments/4buyd3/hot_tub_fuck_machine_m21f20m21f20m20f18m23f21/

One Saturday night my friend wanted me to come with him to a party. I didn’t have anything else on, so I agreed. It was a big 21st out in a paddock, there were hundreds of people there and they even had a blue-grass band playing in a barn. It was a pretty cool party but we didn’t know many people there, so after a couple of hours we decided to go back to my friend’s house and get drunk. We got to his house and I was pleased to see that his attractive younger sister (Alison) was home with a friend (Mel). Alison was reasonably pretty girl with a great body and perfectly rounded C-cup tits. Mel was a cute little freckled girl with B-cup boobs. She was slightly chubby, but in a cute puppy-fat kind of way.

Anyway, these girls were just hanging out in the kitchen drinking, so we decided to join them. Before long we are all a bit tipsy and we start flirting with each other (well my friend and Alison don’t flirt with each other! But he flirted with Mel and Alison flirted with me). Alison and Mel start talking about all the slutty girls they know and how they dress. Alison gets the idea in her head that Mel and her should dress up like these skanks that they are talking about for some reaons. So one at a time, they go off for a few minutes and then come back, each time looking sluttier and sluttier. Eventually Alison comes out in wearing nothing but some very short shorts and a crop top she still has that she says hasn’t fit for years. Her tits look glorious in it: the material has thinned out so much that I can see her nipples clearly through it, it has a bunch of holes in it and best of all, it’s so small there is clear underboob showing. I’m standing there struggling not to get a boner over Alison cavorting around in this tiny top, meanwhile, I look over at my friend and he looks surprisingly cool about it all.

To my disappointment shortly afterwards Alison and Mel say that they are tired and that they are going to bed. My friend and I stay up for a little longer and have another drink, then we head to bed too. My friend’s bedroom is next to Alison’s and as we walk past her shut door, we can hear giggling. We burst in the door and attack Mel, who is in a sleeping bag on the floor next to Alison’s bed. It’s dark, but my friend holds her down and I tickle her, she squeals and writhes, trying to escape. After a couple of minutes of this, my friend and I lay on the carpet and start chatting to the girls again (its almost pitch black, with Alison’s bed on my right, Mel in her sleeping bag to my left and my friend on the other side of Mel). I soon notice that Mel is slowly sidling up towards me in the darkness. I take a risk and reach down in to her sleeping bag, I pull up Mel’s top up a little and half-heartedly tickle her for a few seconds before resting my hand on her ever-so-slightly rounded belly. The gamble pays off and she doesn’t move my hand, she just moves a little closer. We all keep talking and I gently caress the skin on Mel’s stomach, she sighs quietly. I take another risk and slowly slide my hand up towards her tits. I can hear her hold her breath as I move my hand further up her body and soon I start to feel the rounded softness of her breast. I cup it and take her nipple in between my finger and thumb and as I squeeze she moans ever so softly in my ear.

Then she grabs my hand and pulls it off her breast. I’m disappointed for a moment, but my heart skips a beat as she guides my hand down past her stomach and into her panties. My fingers go through her thin tuft of hair, over the edge and find her clitoris. I rub her slowly, methodically and quietly. She presses her mouth against my ear and exhales with pleasure. As she gets closer she starts bucking her hips slightly. At first she does a good job of keeping quiet, but as time goes on, she has more and more trouble keeping her voice even when talks (the conversation is continuing around us) and suppressing her moans. Her pussy is getting wet enough that it is starting to make audible squelching noises. As she cums, she gasps loudly, causing Alison to sit and up and yell ‘did you just cum Mel?’ She turns on a light and looks mock outraged at me ‘are you fingering her?!’. She yells at my friend and I to get out of her room and laughingly, we head out to his room.

My friend is pretty tired at this point and soon goes to sleep, but I’ve drunk too much and I have to pee. I get up and walk past Alison’s room (I can hear more giggling coming from inside, it takes all my willpower to not go in there again) and to the bathroom. I’m only in my briefs and t-shirt and as I pull my cock out, I can hear a quiet shuffling outside, I look 90 degrees to my right and see that Mel is standing outside and has pulled the door slightly ajar and is now staring creepily at my penis. “Argh, what are you doing?” I say laughingly, Mel seems to ignore me and keeps looking at my cock. “You’ve got a nice big one, don’t you?” she says (it’s not that big, it’s not even hard at that point). She walks into the bathroom and grabs my penis. I kiss her and my cock hardens and thickens in her hand. Mel breaks off the kiss to watch my penis grow with an amazed look on her face. “Can I kiss it?” She asks me earnestly. I laugh again and say, “yeah sure, as long you take your top off”. “Really?” she asks geniunely, like I’m doing her a massive favour by letting her show me her tits and suck my cock “You really want to see my tiny tits?”. “Yep, sure do” I reply before she pulls her top off. She then gets on her knees and tentatively puts my cock in her mouth. It feels great, but at the same time it’s obviously she doesn’t know what she is doing.

I hear laughing and turn to see that Alison is now at the doorway. “Mel’s never sucked a cock before, she doesn’t know how to” she says petulantly. “How about you show her?” I say. “Ok, watch closely Mel” she says, kneeling in front of me. Alison grabs my cock out of Mel’s hand and pops it in her mouth. As great as it felt to just be sitting in Mel’s mouth; Alison just takes it to a whole other level. She is an amazing cock-sucker. Unfortunately she stops after about thirty seconds and stands up, telling Mel to finish the job. Mel puts my cock back in her mouth and starts blowing me. Her technique is better than before, but still pretty uncoordinated. Alison smiles at me and puts her arm around me , I reach up her top and fondle one of her breasts. Before long, I feel like I am going to cum. I feel like I should pull out, its been a long night of build-up and I know its going to be a big load, poor Mel might not know what to do with it. However as I look down at her, she looks back up at me with her piercing blue eyes and I can’t bring myself to stop her. As I tell her I am cumming she maintains eye contact and looks all excited, but as I start shooting into her mouth and down her throat, she closes her eyes, pulls away slightly and makes little gagging noises. But to her credit she stays on my cock, although a lot of it starts spilling out of her mouth and running down her chest. When I’m done I slump against the wall of the bathroom as Alison congratulates Mel and helps her clean up.

I kiss both of them goodnight and head back to my sleeping bag next to my unsuspecting friend.
