A partial rear view of Pablo (Gonzalo Sánchez Salas, 13) before he masturbates [nothing shown].

A man forces himself on top of Julia, it is implied he rapes her fully clothed, but nothing explicit is shown (only heard).

Pablo and Julia (14) kiss each other and it's implied she does something to his genitals which happens off-camera (we only see him pull up his trunks right after). Next we have Gonzalo is in bed masturbating under the sheets, with flashes of his experience with the girl in his mind, mixed with visions of Paco (the 'stranger').

Pablo goes to a lake with Paco and undresses to his underwear for a swim. After he comes out from the water, he stands in front of the man, removes down his boxers and wrings the water out from it to get his attention, then lies down on his towel next to him and lies there naked for a while. Brief rear and frontal view.

Boy is depantsed by his pals.
