Walked in on my stepsister naked and fucked her missionary still I cummed on her pussy

As I came home unexpectedly, I heard moans from my stepsister's room. I quietly opened the door and saw her naked on the bed, getting pounded by some guy I didn't recognize. He stopped mid-thrust when he saw me, but it was too late. The lust in my eyes overpowered any shame or guilt I had. I strode to the bed, grabbed her hair roughly and pulled her head back for a deep kiss as I positioned myself behind the stranger. I pushed into her tight hole while my cock rubbed against the wetness between her legs, making her moan louder. We fucked her together, each taking turns claiming her body until we both cried out and filled her with our cum. As I pulled out, I aimed my cock at her pretty face and shot my load all over it, joining the stranger's cum already there. She gigg She giggled as she licked her lips, tasting the salty mix of their fluids.
