Peter Green, the naive stepson, returns home from college to find his stepmom, Bianca Bangs, and stepsister, Tiffany Fox, waiting for him with a surprise. They've been using his absence to explore their own desires and now they're ready to include him in their games. Bianca, a milf with an insatiable appetite, has been training Tiffany in the art of pleasure. They've been practicing their skills on each other, their moans echoing through the house. Now, they want to put their newfound talents to the test on Peter. They strip him naked, their hands and mouths exploring every inch of his body, before Tiffany takes his throbbing cock into her mouth, learning to pleasure him just as Bianca has taught her.
