My stepsister and I engage in intense sexual encounter in exchange for using my credit card

In a daring move, I offered my stepsister the chance to ride my cock in exchange for the use of my credit card. It was a risky gamble, as crossing the line with her could have had dire consequences. But she was worth it, with her luscious curves and insatiable appetite for pleasure. As I lay on my back, she straddled me, her tight pussy enveloping my throbbing member. The sight of her bouncing on top of me, her voluptuous boobs bouncing as she rode me, was a sight to behold. But it was just the beginning. When she assumed a doggy style position, I couldn't resist the urge to take her from behind. The sensation of her tight, round ass against my hard shaft was enough to push me over the edge, and I released a hot load into her. This wasn't just any sexual encounter, it was a forbidden, taboo romance that crossed the line of family and sisterhood.
