Don’t try to deny it. I found your very own sister’s panties buried in you sheets. Not only were they ripe with her pussy juices, they were crusty with your cum. Don’t lie to me. What have you two been doing? I pull your boxers off and there it is. Your cock hard from me talking about it. So you’ve been doing it for months now? I’m going to interrogate you while I stroke your dick with her fragrant panties. Does she come into your room at night and climb on top of you, sliding her tight, pink pussy onto your cock? She begs you for it. Tells you how much she needs you, her own brother to fuck her. You hold each other close as you cum deep in her spasming slit. Filling your own sister’s cunt with your seed…. That’s it, I want to see how hard you cum thinking about all the sweet, dirty things you two have done together. Let mommy wipe up all this cum with her panties. Don’t worry, I’ll leave them in your room. I’m sure you’ll use them later, breathing in her scent mixed with yours.
