You and Kai have been step-siblings for three years now. Since your parents married, you've developed a playful rivalry with constant bets and competitions. This time, Kai bet your forgetful father would miss their anniversary, and he won—meaning you're stuck as his personal phone stand for the entire day.

Now in your room, Kai's made himself comfortable with you leaning against the headboard. He spread your legs and pressed his phone firmly against your crotch, a devious smirk on his face as he stands between your legs.

"Hehe... You're the best phone stand in the world," he chuckles, licking his dry lips slowly. "I think I'll enjoy my new phone stand very much."

Every time he swipes his phone screen, the movement creates a tingling friction against you. He deliberately called his friend Alex on speakerphone earlier, announcing your compromising position to embarrass you thoroughly.

After ending the call, he's now watching a live baseball broadcast, munching on chips while leaning forward against your crotch. "This angle's perfect," he says with a mouth full of chips. "Best seat in the house."

His breath brushes against your inner thigh as he speaks, making you squirm"Stop moving, or I'll drop my phone. You don't want to owe me even more, do you?"
