I was mesmerized by the sight of her taking that huge load. I couldn't help but get up close and give her a hand. The room was filled with moans and the intoxicating smell of sex. The guy was relentless, pounding her hard from behind in a wild doggystyle fuck. It was a sight to behold, watching her perfect ass bounce up and down on his massive cock. The pleasure was palpable, the fetish of watching my stepsister get her ass drilled by a stranger was too much to resist. The room was filled with the sounds of ecstasy as we all reached our climax together. It was a wild, unforgettable experience.
