My sista desired 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 desired my big cock in her mouth and I just couldn't resist the temptation. I let her give me a fellate blowjob and rail my big lollipop 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!
