This story is from thirteen years ago when I (F20 at time) was on summer break from college. My sister Jane (F18 at time) was going out with a local guy Matt (M20) for a few months. I had been in school with him but didn’t know him well until he started dating my sister.

Matt was tall, athletic and handsome, a bit of a stud really. Admittedly my sister was hotter than me, with a perfect body but I was also pretty and had nice big perky boobs that I never tried too hard to cover up. They hadn’t had sex at this point, how I know that comes later.

Anyway, one night I was out drinking with friends and I bumped in to Matt at a bar. My sister was working all weekend and wasn’t with him. My friends were going home when he came over and offered to buy me a drink. We chatted and laughed a while. He was extremely charming and funny and great fun to be around.

Eventually he whispered in my ear that he thinks I’m so hot etc. His parents were away so he had the house to himself that weekend and he wanted me to go home with him. I was reluctant and said no at first but I was really turned on and I had a lot to drink.

I couldn’t help myself and we ended up at his place. Our clothes were off and I was blowing him on the bed within minutes. His cock was as big as anyone I had been with before that, really thick and girthy and he was so hard in my mouth.

I didn’t make him cum because I was craving his cock inside me. I moved up beside him and we started kissing, his hands caressed my breasts before he moved down and started playing with my clit. It wasn’t long before I was nice and wet and ready for him. He whispered to me that he would get a condom but he got a pleasant surprise when I told him there was no need. I had just gone on birth control for a menstrual issue at the time so we were going raw.

I spread my legs apart for him and took his cock in my hand as he climbed over me. I guided the tip of his cock to my pussy and let out a low ‘mmmm’ sound as he pushed it gently inside. He thrust slowly at first, before quickening and taking my legs over his shoulders. He took control and I loved it. He continued thrusting hard until he told me he was ready to cum, as if checking was it still ok to nut inside me. I told him to go for it. It was my first time going raw with anybody and i couldn’t wait for him to cum. Very soon after I could feel his load spilling in to me as he groaned with pleasure. I had always wondered what it would be like and I loved the sensation of warmth as he squirted deep in to me.

He pulled out and immediately started working my clit again and after a few minutes I could feel myself building up to orgasm. He sensed it too and stayed going until I was writhing on the bed and feeling the euphoric release as I came with an intense burst of pleasure throughout my body.

I pushed his hand away and we both lay there for a few minutes before I reached for his cock again. I put my hand on his chest signalling him to lay down as I got on top of him. I took his cock in one hand and massaged his balls with the other for a little while and I could see he was liking it. I then pushed up on my knees and slid gently down on him, his cock went in so smoothly and we made a loud squelching sound as I started to move up and down. He was rock hard and having the time of his life.

He fondled my tits and licked and kissed my nipples as I rode him, grinding my clit over his pubic bone. This lasted at least fifteen minutes and neither of us wanted it to end. Eventually he came inside me again, thrusting upwards as he groaned and moaned with pleasure.

He emptied his balls into me another three times over the next few hours, lasting longer each time. The feeling of fucking raw was still a novelty and I couldn’t get enough. He pumped me doggy style for probably 25 minutes straight. It was absolutely amazing watching him pound me from behind with my head buried in the pillow before he spilled yet another load of cum in to me.

His stamina was unbelievable and we couldn’t keep our hands off each other. There was cum all over the bedsheets when we finished, it was insanely hot.

I would have loved to have stayed the night and fuck him again in the morning but there was too much risk of being caught so I figured I had to go home. As I was leaving I warned and begged him not to tell anyone what we did because I was paranoid as fuck my sister and family would find out. They never did, but I had massive feelings of guilt and embarrassment so any time he was around after that I’d make an excuse to be somewhere else.

A few weeks after our night together my sister told me they had had sex and that it was the first time for both of them! I was like ‘WTF’ but obviously couldn’t say that I knew he wasn’t a virgin. I don’t believe I was his first either because he was too good in bed for that.

I was freaking out thinking about the constant awkwardness if they stayed together, and the ongoing risk of getting found out so I was relieved when they broke up in the end, and thankfully my secret stayed buried.

I still get a little turned on thinking about it. He obviously played us both but it was an amazing night that I can’t say I regret at this stage.
