Movie description: "Concept: Swapping". It’s time for a Labs update, which means it’s time to get experimental! This concept is all about swapping, which we have done before, but this time, we’re switching it up even more. While series like Daughter Swap and Sis Swap focus on horny stepbrothers and stepdads swapping stepsisters and stepdaughters, this concept goes in a slightly different direction. Here, there is more freedom for the swap, as anyone could fuck anyone! In this episode, Will and Katrina are worried about their stepson and stepdaughter. Dylan and Summer are both inexperienced with the opposite sex, and Will and Katrina feel like it is their job as stepparents to teach them. They offer up the idea of a swap - Will can fuck Summer if Katrina Will let Dylan fuck her. Will and Katrina shake on it, and the deal is set in motion. Both Summer and Dylan are shocked by the proposition, but curious and horny, they agree. Will and Katrina show Summer and Dylan how to engage in sex, and soon, it’s Summer and Dylan’s turn. Will treats Summer’s pussy right and licks and sucks her clit. The women suck Will and Dylan off before climbing on top to take a ride. As Dylan and Summer are getting the hang of things, they get the opportunity to fuck each other. The stepsiblings jump at the chance, and Dylan buries his cock deep inside of his stepsis. When the men can no longer hold their loads, Dylan cums for his stepmom, and Will gives his stepdaughter a big load to the face.
