My stepsister usually doesn't talk much, and I honestly have no idea what she's thinking. She's the type of girl who's really into the whole 'dark' thing. But for some reason, she gives off a sexy vibe, so I've been looking at her with lustful eyes every day. Then one day, she said, "Do you want to fuck me that badly?" "Sure, go ahead." "Just make sure to wear a condom." "I'm on my phone, so stick it in whenever you want." A businesslike invitation for sex. If she lets me put it in, I'll agree to any condition like this! And finally, the long-awaited insertion... She's still looking at her phone... And her reaction is weak... Or rather, there's no reaction at all! But when I secretly took off the condom and did it raw… my usually unresponsive stepsister started moaning and arching her back, coming over and over! The insane gap drove me wild, making my hips thrust harder. She came screaming again and again. She acts all cool but she's a total slut inside.
