A while ago a friend of mine and I (21 and 21) made a tinder account for threesomes as a joke, but we actually had some matches and last night we met a girl from tinder (20). We ended up at my friend's place, and even tho I was reluctant to do it my friend convinced me so I went with it. Little did I know that the difference between me and him was huge, when we both got naked I was already hard meanwhile he wasn't but still he was already bigger than me. He and the girl laughed and joked a bit about it but we still continued which we was a mistake. When he was fucking her she moaned so hard that she wasn't able to suck me, meanwhile when I fucked her she was so much concentrated on sucking my friend that she would move and my dick would slip out. It was a disaster so I actually got mad and my dick soft which was apparently hilarious for them, I wanted to leave but I ended up making sandwiches and drinks while they kept fucking until they both finished and we ate together what I made.
