Chapter Text

Regen hadn't slept in what seemed like days probably because it was days since his last time of full rest, every time he got close to the sweet bliss of sleep something always came up or someone was in trouble… again. Hes gotten used to only sleeping for minutes before getting bombarded with requests by Poppy or needed to help someone. Regen even almost fell asleep while trying to stitch one of the smiling critters back up.

"Regen you should rest." Was a phrase he was getting far too used to now. And he would rest if he wasn't bothered EVERY COUPLE MINUTES WITH NEW PROBLEMS!! But he wasn't one to deny helping someone, like ever… he was a down bad person pleaser.

"Regen." He jumped at the sound of the voice, he turned his head to see The Doctor(Harley Sawyer) leaning over him, "Ah! Dr. Sawyer Do you need help with anything?" Regen turned fully around and looked up at the computer, "Hm… Yes." His voice always made a shiver go up Regen's spine.

"What Can I help you with?" Regen asked and smiled, "A… experiment. If you will." The electronic man spoke, "I mean, as long as it isn't dangerous of course." Regen nodded in agreement which earned a grunt from The Doctor.

"Come." Regen followed Harley though was stopped on the way.

"Regen! I n—" Poppy started before she noticed the Doctor and stopped.

"He is busy." Dr.Sawyer squinted at Poppy before grabbing Regen, "Come. Now." he grumbled.

Regen was piratically dragged before getting picked up. "Woah! Uh wow? If this experiment was so dire why come a-" he tried to start before realizing The Doctor was ignoring him, "Never mind…" he mumbled and allowed himself to be carried.

"Wait… This isn't the way to your lab?" Regen started to look around.

"That is right. It is the way to your room" The Doctor sounded like he would be smirking if he had a mouth.

"But I thought—" Regen looked up at the screen, which he met the gaze of the electronic eye.

"Well stop thinking." The Doctor huffed and put the man down when they made it to his bedroom.

Regen walked into his room with The Doctor trailing behind him, "So what is t—-" He turned into a tomato when he felt cold metal hands slip under his turtleneck, they grasped his waist, "You will undress and sit on your bed." Dr.Sawyer whispered into his ear.

"Do you understand?" The sharp tips of the cool metal poked at his skin as Regen nodded.

"Good boy." The Doctor purred and let go of the human man, he turned around and left the bedroom.

Regen took a shaky breath, he was visibly flushed and well… bothered. He blushed more and covered his face with his hands, "God." he mumbled and sighed, he pulled his hands away and started to undress. First were his shoes and socks. He then took his vest off and folded it before placing it on his makeshift dresser, next he took his turtleneck off and then his pants before also folding those clothes and putting them on the dresser too. Leaving himself in just his boxers.

He blushed more and went over to his bed, he sat down on the edge and waited.

Dr. Sawyer walked back in after a few moments, "Hmm… you missed a article of clothing." The Doctor huffed and walked over.

"Oh!" Regen blushed and looked down at himself, before he could speak again Dr.Sawyer had stepped in front of him and was already pulling at the waistband.

"I-I can take them off myself!" He stammered but stopped when the doctor leaned over him, "I will do it. You relax." the computer eye spoke roughly. Regen nodded and lifted his hips, the metal hands pulled the boxers down and off his legs.

"Your body is already begging." The Doctor scoffed, Regen looked away quickly if it was possible he would be blushing so much more.

(NSFW STARTS HERE THIS WILL BE EXPLICIT!!!!!!)

Regen's cunt was already wet, he could feel the coolness roll on his skin, that was abnormally hot.

"No need to be so shy my angel." The doctor piratically purred, his metal hands caressed Regen's thighs.

"S-So what is this experiment?" Regen turned his head back towards Dr.Sawyer.

"Hm? Oh… yes the experiment." The eye closed and then he tilted his computer head. "It is to see how long you can last against me, dear." The doctor chuckled, Regen blushed more and stammered out a response, "L-Last?" Dr. Sawyer hummed and pushed the man further up on the bed.

"Now do as the doctor tells you. Lean against your… mountain of pillows and lay down with your legs spread open." The Doctor spoke in a soft tone, which made Regen do as told.

Regen did obey and laid against his mound of pillows, opened his legs a bit and watched the Doctor. Harley got on the bed and sat on his knees in front of the human, he scowled and put his cold metal hands on Regen's thighs again, "When I say spread," The doctor pushed them apart to get a full view of Regen's cunt, "You spread your legs, pet." He hissed.

The metal man leaned in between the human's legs, "Now will you listen to the doctor and be a good boy?" Regen became flustered with the statement but slowly nodded, "Good. Good to hear." The doctor hummed and leaned down, he rested his computer head gently against the human as the clawed metal slowly traveled down towards Regen's core, "Now do tell me if you start to hurt. Got it Angel?" The Doctor murmured which earned a silent nod from the human.

Regen gasped as he felt the cold metal poke at his folds and slowly push into, he bit his lip and shivered while the metal fingers push against his entrance, and soon broke in. Two finger pushed inside of his warm insides, "Make noises." The Doctor sounded as if he had growled.

Regen stopped biting his lip and moaned, The Doctor groaned in response. The metal inside curled and hit his walls, he gasped and arched his back, "D-Doctor!" He managed to let out.

"Am I hurting you my Dear?" Harley muttered and started to pull his fingers out before he was stopped by the feeling of Regen's walls clenching.

"Don't!" Regen gasped and shook his head.

The Doctor hummed and pushed his fingers in further, he sat up a little to watch the human's face. Every time his fingers curled and pressed against his walls, Regen would gasp slightly and lean his head back. "You seem to be enjoying this?" Harley hummed softly and earned another quick nod from the blush faced human, "Good…" He leaned his computer back against Regen.

A panel opened on the The Doctor's computer head, a long slimy metal tongue slid out and pressed against the human skin, "W-When did you get a tongue?" Regen asked between gasped as the Doctor's fingers slowly slid in and out of the pleasured human, "Since I started to upgrade myself Angel." he hummed.

"Oh!" Regen gasped, the Doctor stopped momentarily until Regen started to whine and grind against the metal fingers. "Are you alright my dear?" Harley asked thoughtfully, "I'm better than fine. And I'll be even more happy if-f you keep going" Regen nearly begged.

The Doctor laughed and pulled his fingers out and sat up, looking down at the now disappointed Human, "Wh-Why?" Regen Whined.

"I can tell you're close Angel." The Doctor snarled which cause a louder whine from the human.

"Come on… Yes I am close. Please don't edge me Harley." Regen started to whine and beg.

"Oh Angel." The Doctor growled.

"Do you want it that badly?" He asked

"Yes-"

"Then beg. Beg like a pet would for a treat." The Doctor snarled.

Regen bit his lip and looked away, "p-please." He mumbled, "Louder." The Doctor hissed, "Please Doctor. Please let me finish, I-I need it." The human tried his best to beg to the large metal man, "Good enough." Harley leaned forward, his tongue licked Regen's lips, "Open your mouth." the command was followed immediately. The Doctor pushed his metal tongue into the warm cavity, he explored the human's mouth.

Regen moaned and grabbed onto the wires, he pressed his tongue against the slimy metal. He tried to follow the Doctor when he pulled away but he was pushed down by the metal hands, "Stay still my angel and keep your legs open." Harley hummed and sat up fully .

The Doctor opened a panel and let a thick appendage slide out, "Now for the real experiment. To see how long you can last with this." Harley chuckled as he Regen eyed the appendage that could be properly called a cock.

"T-That's going-" Regen looked up at the eye.

"In you? Yes my dear." The Doctor snickered, "Are you ready?" he hummed and leaned down, he moved forward a bit and grabbed Regen's leg, he lifted it up and slotted between the human's legs. The slithering appendage pressed against Regen's inner thigh, "Now answer dear. Are you ready to start our experiment?" The Doctor purred.

Regen nodded slowly.

"With your angelic voice dear." The doctor scoffed.

"Y-Yes… I'm ready." The human blushed, the stuttered earned a soft laugh from Harley.

"Then relax." The metal man hummed.

Regen laid back, taking a deep breath and then he nodded to the computer, he closed his eyes as he felt The Doctor lean over him. Soon he felt pressure against his fold which pulled a soft gasp from his throat, he felt the Doctor grab his wrists and pinned them above his head. Regen opened his eyes and he saw that the computer's eye was closed, he was going to say something until The Doctor suddenly thrust in with no warning, "Doctor!" the human gasped and arched, his head fell back as he tried to pull his hands out of the grip, "Shh." The man mumbled and leaned down, he pressed his computer head into the pillows next to Regen.

The Doctor started with pulling out slowly and roughly thrusting back in which pulled a grunt from the man each time. "Doctor Doctor!" Regen gasped, his legs wrapped around the cool metal waist, "Sounding so heavenly my angel." The Doctor grunted and started to move slightly faster.

The metal hands let go of the human's wrist and instead goes to grasp Regen's waist for leverage, "God Damn it." The Doctor groaned and thrust deeper, Regen gasped and bit his lower lip hard.

"Open your mouth darling." The Doctor muttered.

Regen reluctantly opened his mouth, though eagerly invited the metal tongue that slid in quickly, their tongues danced as The doctor's thrusts became faster and deeper, "Doctor." The human moaned into the tongue play. The doctor suddenly pulled away and pulled fully out.

"What! Why?" The human whined.

"Calm Dear." The doctor hummed and turned them around,Regen blushed as he straddled the metal man.

"Now ride dear." The computer eye closed .

Regen whined and pouted, "Either you do as told or we stop here." The Doctor muttered. The human huffed and lined himself up with and slithering appendage, he slowly sat on it. The metal man grabbed his waist roughly, "Good boy." he groaned. Regen sat fully and right away went straight into going up and down on the metal cock.

Regen's bedroom was filled with the sounds of panting and soft curses as the bed faintly creaked under them.

"Fuck it." The Doctor growled and sat up quickly, Regen did have a moment to process what was going on. The human was pulled off of the metal cock and turned so he was getting face into his pillows,

"Doc—" Regen tried but gasped loudly as The Doctor thrust back in quickly.

"Be as loud as you want angel." The metal man above grunted as he moved in and out of the human quickly. This action was causing the headboard to smack against the back wall, "Fuck! Doctor." Regen moan loudly as he clawed at the pillows , he gasped as he felt biting on his shoulders.

"When di-"

"No questions." The Doctor growled and bit the back of Regen's neck and shoulders.

Regen didn't realize how loud he was getting, "Doctor doctor! Fuck fuck. fuck." he felt his eyes roll back a bit, "Are you close my darling angel?" The Doctor grunted. All the human could do was moan and gasp which made the metal man chuckle. "I'll take take as yes." He hummed and a hand slid down to Regen's clit.

"Come on dear." The Doctor groaned as his thrusts became sloppier and he began to rub and play with the bundle of nerves. Regen had come undone quickly afterwards, he moaned lewdly and went limp against the pillows. The doctor slowly pulled out of the human and hummed softly, his metal appendage was covered in juices, "Good job dear." The computer hummed and reach over to grab some tissues from Regen's side table.

The doctor gently cleaned the human and then himself too, he got out of bed and closed his appendage panel, "How are you d-" The metal man turned around to talk to Regen but instead he saw the human fast asleep, "Huh… Well that's good." The Doctor hummed and covered the human man with the blanket that had been caste off to the side.

"Sleep well my dear." The Doctor hummed and left the bedroom to stand as a guard at the door.

*FINISHED*

-The Aftermath-

Regen woke up hours later, he sat up with his hair sticking up in multiple directions, his backside and shoulders were sore. He slowly shuffled out of bed and limped over to his makeshift dresser, he pulled a pair of boxers and sweatpants out and quickly shuffled into the clothing before putting on a random tank top.

He grumble and went towards his door when he started to hear talking that was getting louder with every passing minute, he swung the door open with no thought on his appearance.

"Regen ar-!" Poppy and Kissy were standing there… outside Regen's door which was being guarded by The Doctor.

"Uh… What's u—"

"Oh MY! Are you ok?!" Poppy sounded panicked

"Huh? What do you mean?" Regen looked down at himself and froze… "OH!" he blushed after yelling, "Uh…" The human looked at Harley who was only watching Poppy and Kissy, "I was trying to cuddle with one of the mini smiling critters. Lets just say it was not happy." he played it off and grabbed a sweater that was sitting next to his door in his room.

"So what's up? Need help?" Regen asked.
