My little sister, who has recently started to act seductively, showed off a cunning knit dress to get male attention. But seeing her defenseless ass sticking out from the knit dress made me so excited that I couldn't hold back and was fully erect! Unable to resist, I immediately inserted myself from behind and ejaculated inside her. Instead of protesting, my sister got even more turned on and started begging for my cock. So, I vigorously pistoned her from behind and came inside her multiple times!
