Step sister challenges me to dance in lingerie and reveal my hot pussy while our stepdads are shopping at the market

I was hanging out in the dorm room with my step sister, biding our time until our stepdads returned from the market. The atmosphere was thick with tension as my step-sis challenged me to dance in my lingerie, revealing my hot pussy to her. I wasn't sure if this was a harmless prank or a prelude to something more risqué. Regardless, I obliged, swaying my hips in the skimpy lingerie, flaunting my curves. As I danced, my step-sis joined in, her own voluptuous figure on full display. The chemistry between us was palpable, our bodies entwined in a passionate embrace. The heat intensified as we moved together, our clothes becoming more and more disheveled. The sight of my step-sis in lingerie, her ample bosom and round ass on full display, was a sight to behold. Our encounter culminated in a steamy session of doggy style, our bodies intertwined in a dance of desire.
