I have a few, but the biggest is either my little sister grinding on a BBC thug at a party (it'd be the first sexual thing she's ever done, and she's 17). If I feel real pervy I'll fap to the thought of her going to a room with the same guy and sucking her first dick, and he blows a huge load in her mouth, on her face and in her hair. Then no matter what happens after she'll have a dirty little secret and have been properly blacked.
I'd also love to have a 16yo dream girl that wants nothing more than to please me sexually, and once I'm done doing everything i could think of, I'd have her start sucking off big niggers and giving them footjobs in front of me, before letting them bend her over and fuck her cute white ass so hard it jiggles like the glass of water in Jurassic Park. Soon the only thing that gets her off more than fucking me is getting fucked hard by BBC and letting them shoot their thick hot cum all over her tiny, smooth painted toes.
pic semirelated, a possible dream girl. if my sister looked like this she'd have already sucked niggerdick
