The Married Woman (1978)

This one starts with a hot blonde—slim, toned, tan lines, and a tiny tattoo on her lower back—getting her ass spanked hard. The guy’s got a good grip, and you can see the red marks forming. Then it switches to two girls going at it: the blonde and a brunette with long wavy hair. The brunette’s got some ink on her arm, and she’s really into eating pussy, spreading her legs wide while the blonde dives in. Later, a guy with glasses and a receding hairline joins, going down on the blonde while she’s lying on floral sheets. The lighting’s soft, so you get a clear view of everything—no shaky cam, just good angles on the action. The girls are into it, and the guy’s not just standing around—he’s getting his face buried in pussy too.
