Young Matt bumps into Wendy, his older sister's 18 year old friend on the way home. Wendy suggests she could "fix" 15 year old Matt's virginity problem. Matt is embarrassed, doesn't really fancy Wendy and is very reluctant... well for a while anyway, but his head is not the only thing doing the thinking and very soon he find himself being tutored and experiencing sexual heaven in-between Wendy's chunky thighs.
