First we see Begona (Laura Morante) lying in bed with her lover, her bare breasts exposed. As she gets out of bed, we see her bare behind. She goes to get ready and moves back to the bed and pulls the covers down revealing her sleeping lover's penis and testicles. She places some kind of note covering his penis.
In another scene, Begona shows up at an orgy where 8 or 10 nude bodies are writhing around on a circular bed. Although they are all nude, mainly we only see butts. There is a brief glimpse of a limp penis and maybe some female breast, it's kind of hard to see.
Begona strips for a man and lays down on a bed totally nude emulating a picture that the man is looking at, breast and bush seen from the side.
Begona is either a nymphomaniac, a prostitute, or both ... it's unclear. She arrives at a strange location and ends up meeting a strange male character wearing a wedding dress. They have sex. A number of other men show up and it is implied that they all have sex with Begona.
After the group sex with the all the men, Begona is shown straddling a bidet, furiously washing her vagina. As she moves her hands away from her vagina, it appears that her labia is shown extending below her pubic hair (again, it's hard to see). Shortly afterwards, she goes into the bathroom to urinate and pulls and rubs at her groin area apparently suspecting some kind of STD or other issue.
During the final scenes, Begona once again goes to the bed where her lover is sleeping and pulls the covers down exposing his penis and testicles. She then moves down and kisses his pubic hair next to his penis, not actually touching it. The guy's penis is seen starting inching out after sensing her kiss.
Two women help a man get a semen sample. One strips and stands behind him with her breasts over his shoulders to help stroke his penis. The other lifts her skirt and pulls down her panties. She stands in front of him and he buries his nose in her thick bush. Then she gives him oral sex and after he ejaculates in her mouth, she deposits it in a sample container.
