I have a bisexual threesome with my girlfriend's step-parents

My girlfriend and I walked in on her step-parents fucking in the kitchen. I tried to stop staring at my girlfriend's stepdad's cock, but I couldn't. I ended up sucking his cock in the dinning. After I sucked his cock, I sneaked into my girlfriend's stepmom's bedroom, pinned her to the bed, and fucked her creamy pussy missionary.
