I've never requested this since it doesn't turn me on. However, i recently saw an sp who absolutely needed to masturbate before she left since it's a must for her to have at least one orgasm per session. She wound up masturbating for a good 15 minutes....she even masturbated past the scheduled end of our session. I eventually got tired of watching her, put on my pygama pants, cracked open a beer and sat down to watch the Jays game while the young lady was busy pleasuring herself on the bed. She did finally achieve orgasm an inning later and took the time to take a shower. I figure she was probably a good half hour late for her next encounter and told the booker some lame excuse (but it was partially true) of why she was running late. I love Montreal!
