In the season premire, sexy witch and actress (in the show) Emma Roberts is at a frat party, when a guy approaches her, she asks if he wants to be her slave. He says "What's in it for me?" and she replies "Don't be stupid, slaves don't get anything."
He has other ideas and spikes her drink, leads her away, and rapes her, sharing her with the frat.
It's mostly quick cuts and close ups of her face as they thrust into her, and they don't get her dress off, but you can see what's going on, and they're taping it and giving directions like "Hold her hair up so we can see her face."
