Jeff went and cleaned up in the shower. He had to get his dad’s cum out of his front. Suddenly he had the thought of what it would’ve been like to have sex with his dad if their genitals had been reversed. His clit grew hard at the thought of giving his dad such a forbidden pleasure. And of the thought of Richie’s eyes rolling back while taking a dick.
Jeff went back to the magic shop quick and bought the device that can reverse his situation. He got home and used it, watching his genitals transform into their originals. His dick was nothing to write home about, 5 inches hard, normal thickness. Still it was plenty to work with. His balls were average as well. He welcomed back his parts.
Now Jeff could hear a conversation/argument his father was having over the phone with his mother. She was gonna be late home from work. Richie hung up on her after their talk and came into Jeff’s room.
Jeff was naked, sitting up in his bed with his blanket covering his newly male privates.
“Son, where is that device you used on your...uh...your thing?” Asked Richie.
“Here you go,” said Jeff, pulling out the previous device from under his bed, “but can I watch? I did pay for the machine.”
“Fine you little pervert,” said his dad all grumpy like. He pulled down his pants and underwear, revealing the dick he just fucked Jeff with not two hours ago. Jeff was getting turned on just seeing Richie naked. Richie attached the device and his junk was transformed. He took it off to explore.
“Wow, it worked!” Exclaimed Richie, whose voice was a little bit higher now that he had gotten rid of his former instrument. He started to explore inside with a finger, forgetting himself in front of his son.
Jeff’s five inch boner was poking under the covers. “Wait, you switched back??” Asked Richie, ripping the covers away from Jeff’s lower body. Sure enough, there was his boner.
“Didn’t anyone ever tell you not to trade your dick for a vag?” Asked Jeff rhetorically as he stood up and forced his cock into his father’s new hole.
“Ooohhh,” moaned Richie, “Ooooohhh Jeff, you are in so much trouble after you finish me off!”
Sounded like permission to Jeff. He began pumping his father while grabbing his father’s hairy little bubble butt. Jeff got brave and even started to finger his dad’s ass as he fucked him around front. He started making out with Richie, feeling his moans go into his own mouth. He had made Richie orgasm multiple times and finally cam himself, into his dad’s vagina.
