I intensely desired my seductive stepsister's large buttocks and ultimately engaged in sexual intercourse with her, culminating in ejaculation onto her visage.

I've harbored a deep longing for my captivating stepsisters' voluptuous derrieres, particularly her generously endowed one. The thought of her massive, round cheeks has been a perpetual source of arousal. One day, I summoned her to the couch, my intention clear. I'm a man who openly indulges in the pleasures of his wife with others, so I asked her to bend over, presenting her ample ass for my wife's partner. She obliged, her thick, European beauty on full display. As she eagerly took him deep inside, I approached, my desire for her overwhelming. I joined the fray, taking her from behind, my cock finding its home in her eager, chubby body. The sight of her massive ass bouncing as we fucked was too much for me to resist, climaxing right onto her generous backside. My wife's partner, sensing my release, offered me his mouth, cleaning me off. It was a truly satisfying encounter.
