It's from the late 90's. In the first scene Ursula Moore is making out with a guy in a van. Another guy is peeping and jackin off. She asks him to join. Then they drive away. In the next scene the three are in a bed, one guy licks her pussy, the other guy licks her ass at the same time (never seen that anywhere else), and they move on to a long DP. Rings any bell ?
