Cheeky fuck - Bottomless on the ball

I never thought I'd meet my long-time school friend Stefan at the ball, who I've always had the hots for. Today he's even travelling completely solo because there was a fight with his girlfriend. We party until the early hours of the morning and he offers to walk me home. Young, you're finally due today! When I get home, I let it slip that I've left the house without my knickers on and he jumps at the chance. But what do I have to realise after a hot blowjob, several changes of position, the hot titty fuck and after he has inseminated me and finally taken off his mask? Well, can you guess already?
