A woman pulls young Pavel (Aleksandr Shishonok, 13) to a basement. When she pulls down his pants, we see his rear. Boy lies on her. Nothing else heppen.
Several boys spy on them.
Guiga peeks through a window to watch where Zeca is being masturbated by a woman, but not until after we see Zeca fondle & suck (presumably, his head obscures the actual act) her breast. Includes close-up shot of her hand on his genitals. Later she performs oral sex on Zeca (also obscured).
