A nude man lies on top of a nude woman as she rocks her hips from side to side. When he rolls off her his erection is visible.
A woman masturbates a man (shown explicitly)
A fully nude man with an erection is on a bed with a woman with only a bra on. She lies down on top of him, he then flips her over for intercourse. As he thrusts into her the top of his shaft is sometimes visible (semi-explicit), and he pulls down her bra to suck her breasts.
The film opens with what appears to be a couple having just finished some form of sex. The woman is in a slip and underwear. As they part and the camera pulls back, you can glimpse the man's penis.
