For a bit of background I (18 M) have this classmate (18 F) who has alway been a bit flirty with me. She’s this petite bubbly brunette with big eyes, nice round bubble butt and cute perky little tits. Since a year back she has a boyfriend that none of us really like and with that the flirting drastically decreased especially the last week since they moved in together. So I figured all that would really ever happen between us would be that one time she drunkenly grabbed my dick cause she had heard a rumour that it was huge and wanted to know if it was true.

Feeling a lot more platonic with her it felt safe to one evening after a few beers tell her straight out that I had a huge crush on her at first (trust me, you would too). We laughed about it but I saw something from the past return in her eyes. Well we spoke nothing more of it and continued drinking. On the way home she followed me all the way to my place, grabbing my arm and pressing her little breasts against it. My heart was racing knowing I’d think of this next time I touched myself when we finally got to my place.

We stood and looked at each other in silence and the tension was very much back. Being drunk and horny I told her she was extremely sexy in her short summer dress. She squeezed her breasts together and mockingly asked if I liked what I saw. I asked her if she wanted to come in for a bit and just got mocked even worse with a “so I can finally ride that big dick of yours?”. Then she told me I could think of her breasts against my arm when I take care of my very obvious erection but that she was gonna go home and ask her boyfriend to strangle her while fucking her his hardest and that maybe she’d give me a thought while imagining how it would feel to take it even deeper. Then patted me on the cheek and said good night.

The next day we texted and agreed that we both said some stupid things that night. She also invited me and some friends over for dinner the next week since she’d have the apartment to herself.

The dinner goes smoothly and I’m glad we can move past how horny I was the other night. Me and my friends go home but on my way home she calls me and asks me to come back to talk about what had happened. I get back and she has changed into an oversized deep necked T-shirt and some skimpy shorts to sleep in. Her nipples are pointing through but I try not to look too much. She pours us both a glass of wine and as we sit on the couch she starts sobbing and telling me she wants to break up with her bf and that I made her realise that with how happy she was with the attention I gave her with my advancements last time. We sit and talk like that with her head against my chest and I notice I can see right down the neck of her T-shirt and just about make out her nipples. Admittedly I get horny but I hope she won’t notice.

After some time she calms down and lies down with her head in my lap and lets out an “oh” as she very obviously noticed I was hard. She looks at me and says it’s fine and that she after all already knew I found her sexy. She moves her head around a bit and says “I guess it wasn’t fully hard last time I touched it cause this is not how I remember it” and then asks if I can stay the night anyway just to keep her company since she’s still feeling a bit shook from everything.

Of course I stay (don’t wanna be a bad friend or horny, hard to say). We get into the bedroom where she just takes her T-shirt and shorts off revealing the most amazing firm little breasts with hard perfectly suckable nipples and tells me she prefers sleeping in just panties. With the guy mind I have it’s only now I start realising how deliberate this all is. I don’t really want to say anything about it though since I don’t want her to cheat on her boyfriend and feel even worse about it all but I also don’t want to ruin my chances of seeing and maybe “accidentally” feeling her body up a bit.

I Convince myself I’ll be able to stop at that and we get into bed. At first very awkwardly but then she asks me to spoon her. At this point I don’t know what to do with my hands as just laying them on her perky little breasts will obviously not be accidental. She grabs my hands and cup them around her breasts saying I have at least deserved a feel after she’s made me this horny as she pushes her butt back against my now rock hard cock. I hear a little moan escape and finally I get to mock her back “seems like I’m not the only horny one here”.

Completely quiet and too horny to sleep I feel her starting to rub her perfect butt against me. I pinch her nipple and tell her I’m still not asleep if that’s what she thinks. She asks if we can at least remove our underwear since we are basically already naked anyway and she’s not gonna stop rubbing now that she’s all wet. So we get naked but as we lay back like before I remind her she has a boyfriend so I’m not gonna fuck her. She moans and tells me she’s only thinking about it. She reaches around to feel the size of it and tells me how good it would feel though. I tell her maybe she could touch herself to help her get her mind back in place.

She starts going and slowly as her moans get more intense she’s rubbing her butt against me in bigger motions slowing down when my dick is almost entering her, almost making the tip slide in. I tell her that would be cheating and start pinching her nipples asking if maybe that could help her cum. She says it’s basically like using a sex toy if I just lay still so it doesn’t count and by this point I’m way too excited to say no and just let her start trying to take my dick.

With one smooth movement of her hips she makes the tip accidentally enter her and even though she’s tight she’s gotten so wet she easily lets it slide all the way inside her taking all of my 8 inches at once where she just stays as she keeps touching herself. I feel her tighten up around my cock as she moans more intensely and I tell her she’s really great at bending the rules of cheating and that I’m sure her boyfriend won’t mind this. Her hips start moving again and she tells me to shut up and fuck her, that’s she’s close and if I wanna cum I better make sure to fill her up with my cum as she’s cumming so she doesn’t change her mind before I can cum. “Yeah I’m sure thats why you want to be filled with my cum” I tell her and she changes her mind and tells me “please hurry up and finish inside me, I’m gonna cum and I want your cum dripping out of me when we are done”. I feel her pussy tighten around my cock as her orgasm starts and I can’t help myself from finishing deep inside her.

After we’re done she gets up to clean herself off and when she gets back we lay and hug as we fall asleep pretending this didn’t happen and we are still just friends sharing a bed.
