As John looks over his new body, running his hand over his thick carpet of chesthair, an idea comes into mind as he grins mischeviously, looking at the body that used to be his. Fearing what his son had in mind, especially when seeing that grin, Bob begins to back up, but it's a bit too late now that John grabs that 8 year old hand, and practically dragging it to the shower. "I want to try something I saw Joe and his boyfriend do once, and now that you're so little, you're the perfect height, daddy."
Once in the shower, John turns the hot water on, letting the steaming water soak them and wash away the bodily fluids covering some parts of their bodies from their swap. Still cowering in fear, Bob just looks up at John who grabs his 12 inch pee-pee, and guides the tip to Bob's young mouth. "Come on daddy, or is it son now? Open your mouth." Bob replies with a stutter. "N..no, t..this is wrong! W..we need to find a way to swap back imme-GLK!" Suddenly Bob is silenced as the tip of what used to be his cock is pushed inside his open mouth as he was trying to speak.
A moan escapes John's mouth as the tip enters his former body's mouth, the sensation being something new and it.. it feels really good! Joe was really on to something here, he thinks to himself as he continues to push his shaft into the young boy's mouth, only getting about halfway until he reaches the back of his throat. Wanting more of the pleasure, and feel more of the warmth on his 12 inch pee-pee, John begins to gently force his former dad further onto his cock, and before he knows it, he was nose-deep into those thick, musky, manly pubes that used to be his with tears welling up in his eyes, humiliated beyond belief.
It wasn't long before John slowly begins to pull back only to push back in again to create a thrusting rhythm, building friction as that great sensation of his heavy balls tingling comes back. "You're doing great kid, fuck this feels good." He moans out as he feels a tingling sensation at the base of his penis and before he knew it, he cums! He shoots load after load of his musky, rich and manly semen to the back of Bob's throat. Reflexes forces Bob to swallow it down, much to his disgust. He tries to pull away, tries to get away from this humiliation but as an 8 year old boy, he doesn't have the strength to pull away as John forces him to swallow it all down.
Once his load dies down, he pulls back and leans down to kiss Bob on the forehead. "That felt really good son, can't wait for next time...John." He says with that evil grin he gave his former dad earlier. Stepping out of the shower, he looks back at Bob. "And son, I expect you to clean up that mess you made earlier, or there will be spankings." He says as he heads downstairs to pop open a beer now that he can finally drink it.
