The narrator, who had been stuck at home due to the virus, was slowly losing their mind. The only thing that kept them sane was peaking at their stepsister's luscious ass. They would ogle her while she showered, admiring how her ass glistened with suds. She also loved to do naked yoga, especially when she thought no one was watching. The narrator even watched her when she made sexy videos for her boyfriend who couldn't come over.
One day, the narrator got caught spying on their stepsister. Surprisingly, she seemed to enjoy it and suggested they take their familial relationship to the next level. She performed a sloppy blowjob on the narrator while they reciprocated by pounding her perfect pussy so good that she forgot about her boyfriend. As the climax approached, the stepsister's big tits bounced as she rode the narrator in cowgirl position. The narrator finally exploded, filling her with cum and earning them both an intense facial. They both collapsed, exhausted but satisfied, knowing they had crossed a line from which there was no return.
