The following morning, Cindy in Bob's body had left for work, leaving Bob in Cindy's body to do some chores around the house. Before Bob could get out of bed however, John came in, wiping his eyes as he goes up to hug his mother's body. "M..mom, I had a nightmare." He whimpers out, with Bob not wanting to alert him with the fact it wasn't really his mom in that body, he holds the young boy close to himself, idly cradling John against her chest. "Easy there, cowboy, it was just a bad dream, whatever it was, it's not going to ha-aaa-"
Bob suddenly feels a sudden shiver, and as does John as John begins to grow taller and taller while Bob starts to shrink. Bob's bust starts to shrink as his body regresses, what was previously his wife's cunt was now turning into his youngest son's cock and balls. Meanwhile, John's chest begun to balloon out and swelling into a bust similar to his mother's. Remembering the changes from last night, Bob realises that he was now about to become his son.
John, in his changing body clings to the shrinking Bob "W..what's happening mom!?" He whimpers out while Bob awkwardly holds John close to his body. "It seems we are becoming each other, dear." Bob says in his new young boy voice as they finish turning into each other.
