I like to let a guy suck my cock - if he then plays on my scrotum. His cock then comes into my mouth and I like to lick the guy's balls. But somehow his penis doesn't get really hard. Let's see what happens when I show him my asshole and we both jerk our cocks ourselves - but somehow the spark of lust doesn't jump over with him. It's already crackling in my sack and my sperm is slowly coming out. But without its juice, that's only half the fun.
