"Yeah," Jesse replied. "As interesting as this is, I want to change back." Nick nodded, and after a few clicks, Jesse was a human man again. Blushing as he realized he was still naked, he quickly went into his room and got clothes on. His mind was still reeling from the changes. He was so surprised at how much he did not realize that his body had changed to that extent. But he kinda liked when he was trying to figure out what had changed. What if they both tried to figure it out?
"Hey Nick!" he said, jogging back to the computer. Nick looked up at him. "What if we both try to figure out what has been changed?"
"I like that idea," Nick answered. "But how would we go about doing that?" Jesse pointed at the screen, particularly where it said "Randomize."
"Yikes," Nick said, very uncertain. "I don't know how I feel about that. What if it changes things so drastically that we can't change back or even know that we should change back?"
"Good point," Jesse said. He looked closely at the "Randomize" feature. He smiled when it revealed a drop-down menu. He noticed that he could specify what was to be randomized. It could just be mental, just physical, or both. The duration could be randomized or not as well as awareness.
"How about randomize only mental and physical?" Jesse suggested. "We keep awareness off for, maybe, a half an hour at the most. In the meantime we try to figure out what it changed. After the hour is up, we'll figure out if we're right."
"That seems reasonable enough," Nick said with a hesitant smile. "Can the changes be linked at least? Make both of our changes be similar to each other. I don't want to end up as part chair part snake thing and you end up as a cow with girl's head."
"I can do that, and make the changes have some humanoid aspect to it," Jesse said. "I too don't want to not be part human in some fashion."
"Then go ahead and do it!" Nick said excitedly. Jesse pressed Enter and turned the monitor off of the computer so they wouldn't see what the Chronivac chose for them.
"Do you feel anything?" Jesse asked after five minutes of just staring at each other in complete silence. He readjusted his shirt. It was a little tight across his chest. But that was the way Nick liked Jesse's shirts. That way his pecs could really be pronounced. Nick's shirt was also pulled tight across his broad chest.
"No," Nick said, shaking his head. He looked down at his 5'10" frame. This prompted Jesse to do the same. He stared down at his own 6'1" body. Same thick thighs and thick brown hair on them. Same size 7 feet. Nothing seemed out of place, even with his extremely plump, round, and firm ass sticking out behind him. The jeans could barely contain them. He briefly wondered why he even bothered with pants anyway. He looked back up to Nick, who had always been an inch taller than him at 6'5". He smiled softly at his handsome face.
"What?" Nick asked him with a grin. "Have you figured out what's changed?" He brushed his blonde hair out of his eyes, pushing it back so it only touched the top of his shoulders. It had been ten minutes since Jesse applied the changes.
"Just looking at you makes me smile is all," Jesse said. Nick flexed his bare pecs in response. Being naked together all the time was very freeing, especially since Nick didn't have to wonder what the movement did to Jesse's 3 inch dick. "And my body just likes looking at yours." They closed the distance between the two of them and locked lips. Jesse's toes on all four of his feet curled in as chills went from his head down his long spine to his short tail. He felt the single inch of his dick throb against his underside.
"God, I love you Nickas," Jessery said after a few minutes, nuzzling his head into Nickas's neck. Being a couple inches shorter than Nichas's 7'1" height made the move extremely easy and familiar ever since they had started dating. They rubbed their extremely muscular, wide, and thick torsos against each other. Their arms held each other close.
"I love you too," Nicholas said. He suddenly took an intake of breath as Jeffery sensually rubbed the fur at the base of Nicholas's back. "And I love it when you do that." He snorted and stomped a hoof in sexual irritation.
"Why do you think I do it so much?" Jeffery said, pulling away slightly and smiling eye-to-eye with Nicholas. Finding another gay centaur like himself who was 7'3" was almost like a miracle.
"Any idea on what could have changed yet?" Nicholas asked. "Because I don't notice anything yet." Jeffery took a step back and looked over Nicholas's body. The human torso was the same beefy man Jeffery loved as was the beautiful blonde fur along Nicholas's equine lower half. Jeffery had to work hard to pull his eyes away from Nicholas's huge equine dick, despite the achingly empty feeling in his pussy. He twitched his rear in slight irritation at the feelings in his groin.
"Is it that time of the month already?" Nicholas asked, sniffing the air. His dick seemed to throb with each breath he took. "Are you already in heat, babe?" The golden ring on his left hand glittered as he brushed Jeffery's long, billowing brown hair.
"Yeah," Jeffery said, panting slightly as his pussy throbbed. "I need you badly. Maybe that's what was changed. I don't think I've ever felt it this intense before."
"I'll go get a condom," Nicholas said. "My head is starting to get a little fuzzy, but I know I don't want foals." He saw the look on his husband's face. "Right now," he clarified. "I don't want foals to happen because the Chronivac made you horny." He quickly trotted away.
"Hurry up, honey!" Jeffery called out, pacing back and forth. "I need you inside me, now!" After what seemed like forever, but really was only several minutes, Nicholas returned in the doorway.
"The condom feels really tight," he complained a little bit, trying to move his erect dick about with his hind legs. "Maybe my dick is a little bigger?"
"I'll be able to tell you that once it's inside me," Jeffery said, panting. His eyes were filled with lust. As Nicholas ran his eyes over him and breathed in his scent, his eyes also seemed to brim over with lust. Without a word, Jeffery almost galloped over and stuck his lips on Nicholas's. They mashed their lips together, their tongues wrestling in each other's mouths. Nicholas kissed Jeffery's neck. He leaned down and began kissing and licking Jeffery's nipples. Jeffery groaned in response. He loved the foreplay before the main event. His nipples always seemed extra sensitive whenever he was in heat as an added bonus of sorts. Nicholas walked around and began kissing Jeffery's lower equine body, rubbing his strong hands all along its length. Jeffery bit his lip and threw his head back, chills running down from his head to the end of his tail, straight into his pussy. As Nicholas got closer, Jeffery raised his tail and turned to present his glistening wet pussy. Nicholas stuck a finger in and Jeffery nearly reared up.
"Oh!" he yelled in pleasure. "More, dammit, MORE!" He glanced back, panting. Nicholas grinned and licked his lips. He removed his finger and lined up to mount. Jeffery closed his eyes and waited in anticipation for that juicy equine dick.
