Karina, the busty, blonde-haired stepmom, finds herself sharing a bed with her stepson, Fredo, during their summer vacation. Unbeknownst to him, Karina is on her period. As they drift off to sleep, Karina's hand rests on Fredo's thigh, inching closer to his hardening cock. In the morning, Fredo's girlfriend wakes up to find Karina's red-stained juices on the sheets, and Fredo's cum-filled condom discarded on the floor, a testament to their taboo, no-condom encounter.
