My stepsister desperately wants to have sex with me, but that's absolutely out of the question! She's cute, but we're siblings, even if it's just by marriage!! However, one day, she discovers my weakness and offers a devil's bargain... "Let's play rape"!? She binds herself and says, "Come on, big brother! Fuck me as hard as you can!" What is she even talking about!? With no choice but to obey, I timidly give her cheek a light slap... But she shouts, "What was that!? Do it for real! Rape me properly until I'm completely broken!" Following my masochistic stepsister's orders, I gradually escalate! I face-fuck her deep in the throat while she cries out, "Stop it, big brother!" Despite being a mess of tears and drool, she's overjoyed, saying, "See, you can do it!" I then drive my raw cock into her soaking wet pussy with relentless, brutal piston fucking! Thanks to my stepsister, I might have just opened a new door to pleasure...
