Stepsis saw hardon & we fucked

My stepsister wanted my opinion on her new sexy white bikini and watching her pose in front of my mirror gave me a hardon she was quick to notice. Fuck! Now she wanted my big cock in her mouth and I just couldn't resist the temptation. I let her give me a deepthroat blowjob and ride my big dick with no rubber, then fucked the bitch from behind like a fucking pervert. Who knew my stepsis was such a slut with such a tight slurping pussy!
