Max and his best friend, Mark, sat in the living room watching TV. Max's sister, Lisa, walked in wearing a short skirt and no panties. She sat down between them, her legs spread, and playfully hit Max on the arm before reaching over to mess with the TV remote. As they all watched TV, Lisa's hands constantly brushed against Max's thigh and occasionally found their way to his erection. Mark noticed what was happening but chose to ignore it, enjoying the show. Later that night, after everyone else had gone to bed, Max and Lisa snuck out of their bedrooms and into the living room where they started making out on the couch. Lisa unzipped Max's pants and started sucking on his cock while leaning back against Mark's pillow from the guest room. They continued their taboo tryst until they heard their dad coming downstairs to use the bathroom.
