[MF] It was an accident!…a happy accident

So back when I [M] 23 at the time, was in uni (most of my stories are from around that time) I was out one weekend evening, bar hopping with friends etc and got talking to a girl I knew [F] 22 at the time, but not well. More of a friend of a friend. We got on well, I bought her drinks, made her laugh and all that jazz. So as the night wound down I bit the bullet and invited her back to mine. She agreed and came back.
Pretty much instantly we were on each other. Clothes coming off before we even reached the bedroom.
We spent god knows how long fucking. In my memory it was probably a good 2 hours of fucking on and off. After this time I wasn’t so sure how long I could keep it in, but I was having fun so did my best. I was fucking her raw. I know, not the smartest thing to do for a one night stand even though she was on contraception. Anyway, I digress.
After around 1 1/2 hours – 2 hours, her phone buzzes and lights up. I didn’t take any notice of it, but I still remember her exact words. “Just ignore it, it’ll be my boyfriend wondering where I am” and in that moment my really naughty side appeared and knowing that she was cheating on her boyfriend with a random guy she met only 3 or 4 hours earlier sent me over the edge and I just came inside her right there and then. She definitely knew what she was doing because she came again at the same time.
She didn’t stay much longer after that because turns out he’d also been out with friends that night and they had planned to meet up. So she left to go meet him.
The idea that he may be getting sloppy seconds after I filled her with cum and he doesn’t even know about it made me so horny I was even sadder to see her go.
Never saw her again. I wonder what she’s doing now 😂

As always, thanks for reading.

Your ever Voyeuristic Gentleman
