In this steamy continuation of our naughty roleplay, I find myself once again succumbing to my step-sister's insatiable appetite for a massive cock. As I eagerly unzipped her tight jeans, I revealed the monstrous member she craved so desperately. With a mix of shock and excitement, she eagerly took it into her mouth, her petite frame barely able to accommodate the colossal size. Her eyes sparkled with pleasure as she savored every inch, her tongue dancing over the sensitive tip. But that was just the beginning. As she lay back, I positioned myself between her legs, my throbbing desire perfectly aligned with her moist opening. With a gasp, I thrust inside her, feeling her tight, warm pussy envelop me. The intoxicating sensation was too much to resist, and I found myself lost in the rhythm of our passionate encounter. When I finally reached the peak of pleasure, I released my hot load, filling her eager mouth with my essence. This was a taboo adventure I never wanted to end, and I hoped it would last forever.
