If four families each gave one member to form a new family, what would happen? Everyone in the group has been invited to a costume party in this episode of Family Swap. After deliberating for a family get-together, they settle on an old cartoon. Hime Marie believes her swap brother Kyle Mason will look fantastic as her scruffy handler and she wants to be the crime-fighting puppy. That leaves the preppy guy for Mike Mancini, the switch dad, and the preppy chick for Aiden Ashley, the swap mum. Hime's swap parents give them a boundary lecture while she flirts with her brother. The family is excited about moving on with their collective costume, even with Aiden and Mike's admonition. They all look amazing when they gather again in the living room. Resuming his flirtatious behaviour, Kyle asks Hime if she would want a snack. She claims that Kyle may make her a dog. Though Aiden and Mike remain underwhelmed, Mike eventually diverts the attention of his swap wife by requesting assistance with his tie. Kyle and Hime go crazy snapping provocative selfies in their costumes the moment their switch parents aren't looking. Kyle pulls out Hime's costume and inserts his dick to really do his switch sis in doggy until it tears at the bottom. Seeing their exchange kids fucking makes Mike and Aiden angry at first, but it's also kind of exciting. After spotting Mike's hardon, Aiden concludes that perhaps some group sex isn't all that horrible after all. Aiden drops to her knees, pulls out Mike's fuck stick, and gives him a blowjob that both Kyle and Hime are eager to copy. Next, things get intense between Kyle and Hime as Kyle sits down on the couch and Hime climbs on top of him to straddle him and give him a rough ride. Mike and Aiden quickly catch up, and before long, the two girls are bouncing together in sync. These days, the girls won't be content with just one dick. They trade cocks, allowing Hime to go on Mike's dick and Aiden to get on Kyle's, all while wearing cowgirl costumes. Returning the favour, Kyle and Mike give the girls a hearty dose of vitamin D as they roll onto their backs together. When the girls switch partners one last time and get into doggy, there's no stopping the guys from cumming hard. Mike gives Hime a large creampie after Kyle first goes wild all over Aiden's behind.
