"And done" Randall stripped naked. Jay followed his boyfriends lead and studied both of their bodies.
"Nothing's different."
"The change will take some time, but we have the house to ourselves. Let's start" the two men stared into each other's eyes. Jay leaned in for a kiss, then lightly pushed Randall back onto his bed.
"Tell me what you want" Jay stood in a seductive pose, his hand stroking his beard, down his treasure trail, and gripping his fat rod.
"I want your cock inside me". Jay grinned and climbed on top of the smaller man. The pair was playing with each others tongues and grinding until both were hard. Randall rolled over with his ass in the air like he was in heat. He swayed his hips side to side and giggled, "I already know what you want". Jay grabbed hold of Randall's shoulders and slowly slid his dick in the twink's puckered asshole at first and then thrust himself all the way in, making Randall gasp and bite his lip. He gyrated with slow, even thrusts and held Randall close. Randall loved the warmth of Jay's gargantuan stomach and moobs resting on top of him, with fat nipples poking his back and muscular arms clasping on to him. But this feeling was getting lighter. With each thrust Jay was loosing weight. It started with his musculature, his arms became skinnier and grip on Randall less powerful, and his shoulders and back lost a great amount of width. Then his stomach and the rest of his body lost fat until his only lightly padded. The only areas that didn't loose weight were his moobs and ass. Jay didn't notice such dramatic changes because he was lost in arousal. He was thrusting faster and harder, and Randall was moaning, "Yes! Fuck me harder baby". Jay's forest of body hair and beard receded, leaving him bare and smooth, save for his mustache. Rather, his bald head grew hair, giving him a pompadour comb over and braided rat-tail. There was so much pressure, as if all the weight he had lost was concentrated in his dick, and he shot inside Randall's ass. He let go of Randall and layed down next to him. Finishing his transformation, the tattoos on his arms changed into rose petal and thorn designs, and a heart with Randall's name.
"Did you enjoy your first time?" Jay cleared his throat. His voice sounded higher, was he really that exhausted?
"You were amazing, Baby" Randall nodded, "But I'm more excited for round two. Look at you, you look so hot right now."
"Hehe, yeah? Did the change kick in?" Jay grabbed his glasses off the nightstand and looked at his reflection in his closet mirror. "Oh my God! Haha, this is crazy. One of the first things I did with the Chronivac is make myself bigger. I even forget how small I use to be".
"I know you're a freak for muscular men, that's why I did this". Randall could still feel the warm jizz in his ass, which blew up with muscle. This warmth spread down his legs, expanding his thighs and calves. Then up, giving him a pelvic V and prominent abs. His shoulders broadened and his chest grew out into meaty pecs, pushing his hard nipples outward. He flexed his giant arms and cracked his neck, which grew to fit the rest of his body. It wasn't long before Randall was as muscular as Jay had been before. Randall's jaw became large and chiseled, and a shadow of hair grew on his face. He untied his bun and pulled all his hair to one side, winking at Jay with steely black eyes. "Are you down for some role reversal?"
"You know, normally I'd say no, but... you must have given me some mental changes because I'm about to say go for it Baby!" Jay spread his legs laying face down, "Just go easy, okay?"
"You didn't go very easy on me. C'mere Babe." Randall gripped Jay's braid with a strong fist and yanked his head back, then groped a fat moob with the other hand, holding him close while pounding his tight ass.
