I would say another example is 1974's Teenage Stepmother with Darby lloyd Raines, jamie Gillis, Eric Edwards, and Day Jason. The actors are all practically laughing through the dialogue and you can tell they're all having a good time with each other. It's a shoestring plot that no one takes too seriously in which a newly married woman has to have sex every hor on the hour. There's a scorching scene between Jamie Gillis and Day Jason in which the instrumental version of Shaft plays in the background. For those of you who (like me) enjoy a hairy pussy - look no further than Day Jason. Perhaps because it's ebony colored it looks more pronounced, but if you get offended by a massive triangle of bush, hair along the lips and and around the asshole, you may not like the scene. But she does give a thorough and deep blowjob.
