Girl from S.E.X. (1982)
Starts with a solo blonde, early 20s, slim and tanned, touching herself in the bathroom. Natural light hits her athletic build. Things jump to full intercourse when a tattooed guy with piercings shows up. He’s got a muscular frame, short dark hair. The bedroom scene is dimly lit but you see everything. She rides him hard, leaning back so you get a good view of her body. The shower oral later is bright and steamy — she’s on her knees, taking her time. Guy finishes solo, jacking off in profile view.
