Are you having fun? I'm sure it's much more exciting to be up close helping me rather than standing in that dark corner like some perv like you did earlier!
(rub yourself though your pants until your hard then let go and stay hard, slowly toughing though your pants when you feel yourself getting soft for 5 minutes)
Oh....your cock is growing hard a little bit again? That just won't do. Maybe you should just sit back and watch me from a distance for a few minutes, okay?
(Let your cock grow soft again before you continue)
