When I returned to my parents' house after a long time, my childhood friend, who was my first love, was there with my father. I discovered that the two of them were dating! That night, I got drunk and was about to go to bed in the middle of the night when I saw my father and childhood friend, their bodies entwined like snakes, making out with each other. In the end, my childhood friend caught my eye and let me peek at her having sex, drowning in intense pleasure. When we were alone at home, my emotions were overflowing with love, jealousy, regret, and sadness, and I stirred up her vagina with my hard penis.
