Her brother gets her tied up and ready for an assfucking
He arrives from the party and still with some of the effects of alcohol and drugs that are common in youth today, he can’t believe what he is seeing. His first instinct was to think it was a hallucination thanks to how drugged he is, but after squeezing his eyes for a while to see clearly, he realizes that his sister has her hands tied and ready for an ass-fucking. He even had a dilator behind him, so all he did was take it out and immediately put his cock in her ass so that the young slut can start enjoying himself while he fucks her anal.
