I (19f) was sat around a table with 8 friends, 4 guys 4 girls, four of them are couples with eachother, 2 have partners not in the group and two are virgins. We got onto the concept of sex and they were all saying how vanilla stuff is all they’re interested in with eachother really cutesy and nice. When asked about my experience I stammered out that I was a virgin like the others two. Secretly however that morning I’d had a screaming shaking orgasm on the cock of a rude dirty fat old man and then swallowed and worshipped his cock until he gripped the back of my head and pumped a load down my throat. I was sitting slightly apart just in case they could smell the cum on my breath or dried slightly on my chest. It got me so horny the taboo that when I got home I rode a dildo on my floor biting down on a belt around my neck that served as a choke collar as well so my parents wouldn’t hear me squeal.
