A teen brother(Guilherme) takes his sister(Sofia) to a party where she makes out with couple of guys, lots of other teen couples are seen making out, most of them in their underwear, no nudity is shown in the party (except a naked woman is shown on tv for few seconds).

Guilherme tells his sister "I don't believe that you're still a virgin". It is understood that Sofia promised her brother that she would loose her virginity to him. Guilherme tries to kiss her but she gets up & leaves.

Guilherme enters his sister's bedroom while she was sleeping, he removes the blanket off her while she wakes up, he starts to squeeze her breast, she lets him lie down beside her, he touches her breast & begins to masturbate while she watches. Near the end she reaches to either finish him or cover him; it's not clear which. (No nudity is shown in this scene but only facial expressions).

Sofia makes out with a guy on a bed while Guilherme watches through a window, we her bare back and, briefly, her breast, all heavily blurred by rain on the window.

Guilherme secretly watches his father having sex with a prostitute, we can only see the woman's breasts. After that Guilherme masturbates. (nothing graphic is shown)

A man dies, perhaps from suicide, and is briefly seen floating in a bathtub, not gross or gory.

Several sensuous scenes between brother and sister are intense and will disturb many, in particular the final one.
