My step sister's ample bosom accidentally encounters my penis during her study session

During my study session, I couldn't help but be distracted by my step sister's ample bosom. Her voluptuous curves were just too enticing to resist, and before I knew it, my hand had found its way to her generous assets. The sensation of her soft skin against my fingers was enough to make me lose control, and I found myself pleasuring her in a way that I knew was strictly off-limits. However, my step sister didn't seem to mind the unexpected attention. In fact, she seemed to enjoy it quite a bit. As I continued to explore her body, she reciprocated with a passionate blowjob, her skilled mouth bringing me to the brink of ecstasy. But the real action began when she assumed the doggystyle position, allowing me to take control of her backside. The sight of her round, fat ass being pleasured by me was enough to drive me wild, and I couldn't help but continue to indulge in this forbidden encounter with my step sister.
