As soon as my younger sister became a college student, she suddenly started to exude sex appeal. She showed off an outfit that guys love—a revealing knit dress that clearly outlined her breasts and butt, with her defenseless protruding ass visible from the hem. I instantly felt her femininity and couldn't hold back any longer—full erection! I lost control and immediately inserted myself from behind & ejaculated inside her… I thought it was over, but my sister, whose desire had been ignited, came seeking my dick! What a development! I vigorously pistoned in and out of my real sister multiple times, cumming inside her multiple times!
