The glowing was beginning to dim, just as soon as it begun. As soon as it had begun, it had faded. However, their veins had remained a dark purple color. Suddenly, a metamorphosis began to occur to both Zach and Antonio.
Zach’s hair had become more curly, and more of a jet black instead of a brown. Thick black had sprouted all over Zach’s jawline where it had never been before, and small crow’s feet had formed near his eyes. His skin darkened slightly, and his eyebrows grew a bit thicker. He had already looked like his dad before, but now he was nearly a clone.
The beefiness of his body was dissolving, as his body started to tone up, and become a lot more defined because of his weight loss. Hair had sprouted on his chest, covering both his toned pecs. Both of his hands grew another inch, as his dad was notorious for having big hands for a guy his size.
His testicles sagged a bit more than they already did, and slightly expanded from the size of gum-balls, to the size of walnuts. His penis begun to inflate slightly, traveling down his leg a bit more than usual. The blood that had inflated his dick stayed there, leaving it with a nice amount of girth. Finally, Zach had developed his father’s foreskin, as he was never circumcised in his home country. The skin of his penis moved up and covered up the head, now perfectly mimicking Antonio’s penis. Its ugly head poked slightly out the bottom of Zach’s boxers.
His arms grew a bit longer, as they adapted to Antonio’s lengthy body. Zach’s feet grew to a size 14, the same as his father’s, from a size 12.
Meanwhile, in his parent’s room
Antonio laid asleep in a pair of boxers, as he had finished pleasuring his wife about an hour or so earlier. She laid next to him, half naked as well, but also blind to the light show that was happening beside her. The glowing had subsided, and his change had initiated.
The hair on his chest looked as if it was retreating back into his body, as the hair on top of his hair became a straighter. His 5 O’clock shadow also retracted back into his skin, leaving him with a smoother face. The few wrinkles that Antonio did have, soon faded away as well, leaving his face completely clear.
The mass of his body grew, as his shoulders and arms beefed up, causing him to take a bit more space on the bed. Antonio’s skin then lighted up a bit, making him more of an olive color rather than brown. His torso had lost its definition, but was still fairly flat in comparison to how it was.
Underneath his boxers, his testicles shrank a bit, as the did not sag as much as the had used to. Antonio’s foreskin melted away, and his dick deflated like it had popped a tire. It only shrank down about two inches, but he also lost that in girth.
Antonio’s arms, hands, and feet then began the shrink, as his lengthy body parts were replaced with his son’s average ones.
Their bodies had now completely replaced each other, as Zach was sound asleep in his bed with Antonio’s body, and Antonio did the same in Zach’s body. Their rings had stayed on their fingers through their entire transformation, but then sunk into their skin forming a dark ring around their finger in its place.
