I've always had a crush on my dad's friend [R] for as long as I can remember. Even though R is older than my dad, he's very good looking for his age and he's always been so nice to me and takes care of me. A week after I turned 18 we were all spending a weekend at R's cabin he has on a lake. Usually only my dad goes so they can go fishing or take the boat out, etc.

But I got invited as a birthday present and R brought his gf, idk what happened but R and her got in a fight (she's a bit of a bitch tbh and I've always thought he deserved someone prettier lol) so my dad offered to take her out on the boat, I think so her and R could get some space and calm down.

After they left I came back inside from the pool in my bikini and was talking to R about what happened because I wasn't there for the fight, he told me he's been wanting to break up with her for a while. I hugged him but because he was sitting down I had to lean over and while I was hugging him, he pulled me closer to him and down so that I was sitting on his lap and almost straddling him.

Everything next happened so fast, he kissed me and next my bikini top was pulled down. He was sucking on my nipples while he pulled my bottoms to the side and slide his finger inside of me. He tried pushing a second finger in me and I could barely take it, this must have turned him on because almost immediately he put me on my back, got on top of me, pulled out his cock and shoved it inside of me. He was much bigger than I was expecting and I couldn't help but scream and moan while he pounded me. He held me down and told me that he was going to fill me and suddenly I could feel him pumping all his cum in me.
