classic boy-girl thread.

Dirty Susan (1977) Scene 1 -
Georgette Saunders, Roger Caine
Dan (Roger Caine), a private investigator, wakes up in bed with Susan
(Georgette Saunders) but he has no idea how she got there. He doesn't
realize that she is "Dirty Susan", a being who just turns up to help
people with their sexual problems and frustrations. She quickly explains
that she just wants to fuck him. Like most of us in that situation, he
didn't need convincing. Dirty Susan proceeds to give Dan one hell of
a blow job. Dan enjoys that so much he wants a bit more of Susan and
sits her on his cock, reverse cowgirl style. That position gives us a nice
view of her hairy pussy and delicious small tits as she bounces up and
down on Dan's dick. We cut to her turned over and riding Dan in the
more usual position. She rides him until he cums over her ass then gets
off him and licks his cock clean.

Dirty Susan (1977) Scene 4 -
Georgette Saunders, Shaun Costello
Dirty Susan is at it again, this time Shaun Costello gets to enjoy her
in a disjointed scene that had many cuts to another scene (which I
removed). They kiss and then Shaun goes down on her. Georgette
gives Shaun some head before he takes her from behind. There are
some very close up shots of him fucking her hairy, very wet pussy.
She does some reverse cowgirl again while Shaun plays with her clit.
She really gets into it and you can see she is enjoying it. There is no
cum shot in this scene because Susan just disappears, probably to
go help others in sexual need! From memory, I think the couple
screwing in the background are brother and sister (in the film!).
