Maria, a college girl my brother met at a gathering of perverts. Since she expressed a desire to have her session watched closely, I was allowed to attend Maria's exhibitionist session. Maria is stripped down to just her panties, first made to wear a mask before having her nipples sucked. My brother asks her, "You want some stranger to watch you masturbate, don't you?" to which Maria responds with silence. He continues, "Stand right in front of me, let me examine your pussy thoroughly, and then I'll watch you cum over and over through masturbation." Maria softly replies, "Yes..."—her obedient demeanor intensifying the atmosphere of the session.
