One lenghty sex scene with full back and full frontal male and female nudity, consisting of foreplay (no thrusting, no penetration and very little moaning). The scene starts with a man is sitting naked in bed (we only see his bare chest). A young man enters the bedroom: he is fully naked under a robe. He sits on the bed and undresses, making the other man uncomfortable (he tells him that he's not gay). We see the young man's bare abdomen, legs and thighs. A girl then enters the room; she is wearing only a t-shirt (her bare buttocks are visible). She sits on the bed, removes her shirt (her bare breasts are visible), and kisses the younger man. She then removes the blanket on the other man's body (we see his bare thighs and legs) and sits on his lap (we see her bare buttocks and her crotch area); at the same moment the younger man moves and his penis is visible. The man with the girl on top of him caresses her butt and torso, and she touches his chest; meanwhile the younger man kisses him on the head, forehead and neck. The girl then moves, lies on the younger man (once again we see her bare breasts and pubic area) and kisses him. The other man moves as well (we see his bare back and buttocks) and touches the girl's thighs offscreen (we only see his arm moving up and down). Afterwards they change positions one more time; the girl gets on top of the same man again (we see her breasts, butt and pube), and he touches her buttocks with both hands. They kiss repeatedly (the girl also kisses him on the neck), while the younger man touches and kisses the other man's hair, head and forehead. The scene ends here (its lenght is about 4 minutes), but it is implied that the threesome does happen. Briefly after, there is a post-sex sequence in which the three people are sleeping. The older man gets up and off the bed (we see his bare buttocks, the girl's breasts and pube, and the younger man's butt). When he goes back to bed, he kisses the girl twice, tells her she's "very capable", and the sequence ends. After a short while, when the older man is re-thinking about what happened, we see two brief flashbacks of the three people kissing and lying in bed.
In another scene, long about 2 minutes, a man and a girl have sex in the storage closet of a restaurant. It starts with the girl approaching the man (she is wearing an alluring babydoll-like dress); she opens his shirt, then undresses (we see her bare breasts). They start kissing and touching eachother (he also touches her breasts). Afterwards they are seen lying on the floor making out, both half naked (the girl's body is barely covered by her dress and the man is in his boxers). The man puts his hand on her crotch and moves it slowly. They keep kissing and rubbing each other, and the scene ends (it is implied they have sex).
A man leans on a woman who is lying on a bed and kisses her. They make love. We see a close-up of their faces and shoulders as they kiss and moan (no graphic nudity, only one of the woman's breasts is briefly seen). Then we see them lying and talking after sex (only the man's bare chest is shown). The scene is long about 1 minute.

Later on, a girl tells a man about her group and they talk about the sex that happens between them.
