Jason wanted to try something else. He admired being in his father’s body, feeling power behind his muscle and fat, but he wanted try pushing the last potion to its limit. He looked at his father, who looked like Jason, and began to think of some possibilities. Both men were drenched in sweat from the amazing sex they just had, the feeling of summer heat and lust still in the air. Jason finally thought an idea. What if he used the last potion he had to transform the both of them while they had sex? This was a wild idea, as the potion was not intended to transform multiple people. He withheld this information from his father and simply said,
“Hey, let’s go again. I want to try something different this time.”
“Already? I mean sure, I’m still feeling a little horny after all that, but I’m not sure there’s still anything left in my tank.”
“That’s ok, just trust me on this.”
With Jason’s confidence, he moved his father Michael into position. Jason lay his fat gut on his father’s back and rubbed it with his hands. Michael could feel the heat from Jason behind him, the large imposing figuring teasing him with his original weight and presence. Jason pushed his beard onto his father’s neck, kissing him subtly, letting it brush up and down like he always dreamed about. The sensation made Michael moan, as all the knew fetishes he had were overwhelming.
Jason, done with the foreplay, then took his monster cock and put it into his Dad’s ass. He made sure to go slow and steady. Michael began to cry out and moan as the feeling of Jason’s dick riding in and out made him extremely weak. Jason knew all his father’s wants and desires, because not long ago those desires were his own. Jason, as his father was lost in lust, began to unscrew the final potion.
Jason poured it over both of them, wondering if it would change them back or if something unexpected would happen. Either way, they would both had to be satisfied with the result, because there was no way to change either of them into something else immediately. Michael felt the cold liquid pouring down his back onto his chest and butt. Jason felt the liquid pour down his body as well, finding its way towards his cock and torso. They continued to have sex, not know what changes would happen next.
