After a night of passion and sex, David woke up...still in Dan's body. David briefly forgot about the switch as he tiredly made his way to the bathroom. As he passed the mirror on his way to the toilet he glanced at the mirror. "Oh!" he said out loud in Dan's former voice, "that's right, I kinda forgot about what happened". David felt his cock getting hard at the sight of Dan's toned and genetically perfect body in the mirror. The realization that he had jumped from being a healthy, horny, 28 year old guy to a 55 year old guy, (albeit a hot John Stamos look alike guy) finally set in as David rubbed his new chest and realized that a bunch of the chest hairs were gray. What would happen next, David wondered. Would the transformation suddenly reverse itself, would he continue to age in Dan's body, simply losing 26 years? Would he be able to maintain Dan's awesome physique? Would he and Dan become a couple and if so, who would be in whose body? All of these questions and no answers. In the meantime, David (now Dan) got horny looking at himself in the mirror, and laid down in the bathtub naked to pleasure himself and his thick 10 inches at the very thought of how hot this sexy old body looked to him. "Well" thought David, "I suppose I don't mind if it's permanent, because even at 55 Dan's body was hotter than my plain old farm-boy body would ever be". David had hardly finished his thoughts when Dan (still in David's body) started to wake up...
