Taking my petite stepsister's virginity and ejaculating inside her

After a heated argument, I decided to take things to another level with my petite stepsister. In a move of pure revenge, I took her to the guest room and had my way with her. Despite her initial protests, she soon gave in to my advances. I began by exploring her tight ass, not just with my fingers, but with my entire fist. The surprise on her face was priceless, but it quickly turned into pleasure as I continued to push deeper. As I pounded her from behind, she moaned in ecstasy, her body writhing under me. The sight of her tiny frame being taken so thoroughly was enough to push me over the edge. I filled her up, leaving nothing but a sweet, sticky reminder of our encounter.
