Step-Mommy needs some alone time. As she cums, she catches step-Son spying on her, just about to cum himself. The moment he accidentally shoots his cum all over step-Mommy's exposed titties, he opens a time portal, sending him back in time. He arrives in the 80s, greeted by a younger version of his step-mother who is all too ready to cheat on her husband with the handsome stranger who appeared out of nowhere. She is taken aback when he tires to call her "step-Mom," but she is eager to play into these sexy fantasies and be his "step-Mommy." Sharing her generous sexuality, she unleashes her lust upon the stranger and begs for his cum inside of her, never realizing that it was her own step-son from the future. As his cum is dripping out of her pussy onto his still throbbing cock, step-Son is transported back in time another 10 years to the 70s. He awakes in a very comfy bed, greeted again by his own step-mother, 10 more years younger. She mentions how he must have out from too much partying the night before, and that she has been looking out for him. She finds him very handsome and convinces him to get a little loose with some smoked herb. As they give into the sensations, she wants this sexy stranger to take her virginity. He gladly complies, reveling in the impossible opportunity to take his own step-mother's virginity. As her incredibly tight pussy milks his cock dry, he is transported back to the present day where things are not all that they once were. He learns of his own little step-brother, and realizes that somewhere along the way, he must have got his own step-mother pregnant
