Your step-sister bursts into the living room and sits on your lap. She's frantic, nervous, apologizing for being aggressive, but says she needs your help… she tells you that she's a semen addict, and you’re the only man she trusts with this secret.
You hesitate. You’re step-siblings. She has a boyfriend… or had one, until they broke up last week because he couldn’t keep up with her needs for cum.
She starts teasing her chest, begging for your load. She blames you for tempting her, smelling so good after the gym, brimming with testosterone. She knows you’re single, and that your balls must be full of fresh, hot cum, exactly how she likes it.
She unzips her jacket to reveal her beautiful tits. She knows I like them; she’s caught me staring plenty of times. My cock throbs against her breasts as she presses them against me.
"Just relax," she says. "Whip it out. I'll milk you."
I tell her I love her, and I don't want her to suffer…
I agree.
