Rita, Sue and Bob Too!

Rita and Sue are two teenage girls in their final year of school who live on a run down council estate in Bradford. To earn some money, they babysit for Bob and Michelle, a better-off couple who live in a detached house in a nicer part of town. When the couple return later, Michelle pays the girls and tells Bob to give them a lift home. Bob, however, drives them to an out of the way place and proposes to have sex with each of them in the back of his car. They nonchalantly agree, and he and the girls plan to make it a regular thing. By the time they're finished, it's 2:00 a.m.
