A well-endowed young woman exposes her breasts to a young man, and then proceeds to give him a "boob job" - rubbing and massaging his erect penis between her voluptuous breasts until he orgasms and ejaculates all over her face.
Frequent full frontal nudity throughout from four very attractive and voluptuous young women, each of whom has several explicit hardcore sex scenes with the male lead. The male lead, a young man about the same age as the women, also appears fully nude throughout, though not quite as extensively as the women.
A young man accidentally walks in on a nude young woman taking a shower, who offers to teach him about the female body. He also gets naked, and she shows him her genitals. She notices he has an erection, and proceeds to give him oral sex in the "sixty-nine" position. He eventually orgasms and ejaculates all over the bathroom walls and floor, as well as on her face and body.
