Stepbrother's friend caught my sister in a compromising position with her stepbrother. The friend joined in, leading to a wild threesome. Surprisingly, my sister was not involved.
In the heat of the summer, a group of horny teens decided to spice up their day by having a steamy threesome with my stepbrother. Little did I know, they had planned to involve my sister as well. As we were all lounging in the backyard, my stepbrother suddenly found himself in a compromising position with my sister. Caught in the act, my sister was left feeling betrayed and violated by my stepbrother's perverted behavior. Despite her protests, he continued to force himself on her, leaving her with no choice but to fight back. As the situation escalated, my stepbrother's friends joined in, turning it into a wild group sex session. The sight of my sister being fucked by multiple guys was too much for me to handle. I couldn't help but feel disgusted by their perverse actions, and I knew I had to put a stop to it.
