In episode 1, a girl joking humps a man, both are clothed. Not explicit, very brief and meant to be humorous. A few strong sexual references, the worst being a joke about a "circle jerk"
Alma does appear in a bra in about two scenes in first few episodes.
In episode 3, a man fondles the breast of his girlfriend through her clothes.
In episode 3, at 13:25, a woman is naked in front of a group of children. She covers her breasts with her arms and crosses her legs out of embarrassment, mostly blocked by the children's heads.
