Vera's new room-mate is nothing but a man-whore. She has to listen to Jason in bed with other women almost every night. Listening to him moan is torture, she's jealous and she's wet. She can't tell whether she wants to be with him, or just watch him with someone else.
Soon she discovers that she actually wants to do both. Her jealousy and want driving her wet with desire.
And Jason loves it.
