Masturbation fantasies: Amanda, queen of the peep show

He realized having felt something like that on a school trip back in the last year of high school, when during the night two of his roommates produced a bunch of porn magazines and openly masturbated while flipping through them: he felt too embarrassed to do it and mocked them for doing so but after he had to go to the bathroom and jerk off alone, so strong was the arousal he felt.
Almost trembling with the excitement he started wanking with passion, lost in the show. Amanda was teasing her ass with one finger, and near the end of the 10 minutes she turned around, opened her legs wide while sitting on her heels and pushed her hips forward while at the same time bringing her torso and head down towards her crotch: with the length of her member, in that position she managed to not only lick her cock's head but to put it in her mouth. When he saw that he really lost control and while mumbling to himself “yeah, suck your big cock” he quickly jerked his dick, cumming a second later with four spurts that got to the glass and then dribbled all over his jeans and on the seat.

After his cock started going flaccid he regained a bit of composure. He silently cursed at having stained his pants but it didn't really matter that much. He felt a bit ashamed for the gross situation he was in, but still his main issue at the moment was that he wanted to enjoy more of the show. He quickly cleaned up with tissues as good as he could, trying not to miss what was going on beyond the glass. Amanda got out of her awkward self-sucking position and was now jerking off while laying on the stage on her left side, taking her sweet time and looking teasingly at the other men while licking her lips slowly. He noticed that the guy who came before was already gone. By the time he finished cleaning himself and putting in enough money for ten other minutes, two other guys had already come. He watched them jizz, one against the glass, the other apparently in a bunch of tissues he held in his hand.
