Russian girl studying abroad in America and the ending

Samantha Hayes, a Russian international student, hid a camera in her living room before getting into trouble to see what she could record. She called Lucas Frost, the son of the host family, and asked if she could watch TV. Lucas says he wants to play video games, but Samantha tells him his stepmother deleted his games. When he has a tantrum in the living room, Sofie Marie comes out to see what's going on. She tried to comfort Lucas, but when her nipple popped out and Lucas sucked on it, she realized that was the best way to calm him down.
