As I'm on the phone with my girlfriend, my new step-sis with monstrous tits appears in front of me, her hot pants barely covering her creamy thighs. She grinds her hips against my crotch, her hard nipples poking into my chest. I try to resist but she grabs the phone and starts talking dirty to my girlfriend while unzipping my pants. Her juicy lips wrap around my cock as she pleasures herself on top of me. My girlfriend is screaming with pleasure on the other end of the line as my step-sis rides me like a fucking animal. This is too much for me to handle – I need release. With one savage thrust, I pound into my step-sis's tight pussy until we both climax together, our moans echoing in the phone line connecting us all.
