After a night of heavy drinking, I woke up to an unexpected surprise. My step sister was in bed with me, her nightie pulled up high on her thighs, revealing a tantalizing glimpse of her white lace panties. This was not the first time we had shared a bed, but something felt different this time. I couldn't resist the allure of her body, and as I reached out to touch her, she didn't resist. Our hands wandered, exploring each other's bodies in the dim light. The passion escalated quickly, and soon we were engaged in a wild, uninhibited sexual encounter. The intensity was palpable, our bodies moving in rhythm as we explored each other's desires. The roughness of our lovemaking was a stark contrast to our usual encounters, adding an extra layer of excitement. As we reached our climax, we lay there, basking in the afterglow of our unplanned, passionate encounter.
