Jealous stepbrother wants to knock up the stepsister

The stepbrother sees the girl going out with boys and when he touches her ass she gets angry. That's not fair. The boy has a plan and he carries it out. The boy puts chloroform on a towel and puts the towel on the girl's face who passes out. Finally the boy can touch her the way he wants to without her getting angry! The girl turns her over and spreads her legs, naked, to take pictures and touch her pussy. The guy fucks her pussy with his fingers, then he puts his dick in her faint stepsister's mouth and then fucks her hard enjoying the girl's tight pussy until she ejaculates inside the pussy
