Thanks to @juicedmusclepup for allowing me to based the story on his pics. Juiced Muscle Pup Hunter was short but what he lacked in height he made up for in muscles. He had nice thick, short legs, a wide back, defined arms, and a nice bubble ass that turned a lot of people’s heads, both women and men. However, Hunter wasn’t satisfied. He wanted to be bigger, more jacked, and was willing to do anything for it. His dream was to compete on stage during a bodybuilding competition. Hunter wasn’t above using steroids to get there and had shown some promise in using them but it still wasn’t enough. When he wasn’t attending classes at NYU, he spent all of his free time at the gym. One day at the gym, he was working out in his blue tank top that clinged to his round heavy pecs, and a pair of sweatpants. The grey sweatpants did nothing to hide his plump behind. As he worked out his ass stretched the sweatpants, showing off its roundness and thickness. Despite his height, he held himself very well and was cocky in the gym. Hunter was considered one of the gym’s alphas. Hunter just finished his last set of squats and headed toward the locker room, peeling off the sweat soaked tank top as he went. “Had a good workout,” an older man asked as Hunter stopped in front of the gym mirror and flexed. “Pretty good,” Hunter replied as he inspected himself in the locker room mirror for faults which he could only see. “Look like you are in amazing shape,” the older man stood close behind Hunter. “I’m trying. But too damn hard to grow,” Hunter replied as he pulled down his sweats and pulled up his blue compression boxer briefs. He extended his top right leg, shook it, and began to flex his quads. “Maybe I can help,” the stranger pulled out a business card. “I’m Dr. Stone from the university,” the older dignified man extended the card to Hunter. “I am conducting trails on a muscle growth program. I assure you it's all above board.” Hunter looked at the business card and was intrigued, “what I have to do?” The older man smiled, “we developed a new form of steroid that is more effective than any other that is produced now, both legal and let say, not so, without the harmful side effects. Along with our specially designed fitness and diet program, it is guaranteed to see results in only a couple of weeks.” “Sounds too good to be true,” Hunter was skeptical but also more intrigued. He was willing to try anything. He had already tried almost every product he could get his hands on. “Think about it overnight and give my office a call if you are interested in making an appointment,” Dr. Stone smiled. After the Professor left Hunter went into the gym shower to wash up. As usual he took the last shower stall in the rear of the row of curtain covered stalls. As the water washed over his sore muscles, he soaped up his tight, compact body. He loved the feel of his muscles and began fantasizing about how they would feel bigger and jacked. His cock grew hard to the point he had to wrap his fist around his pulsating cock and feverishly jackoff. He lifted upon his toes and arched his back as he shot his load onto the stall’s wall. For the rest of the evening Hunter couldn’t stop thinking about Dr. Stone and his promises to make him bigger. The first thing the next morning, Hunter called and made an appointment to consult with Professor Stone. “I glad you agreed to take part in our program,” Dr. Stone shook Hunter’s hand after he went through all the details and Hunter agreed to all the disclosures. “Now are you already for your first treatment.” “Absolutely,” Hunter replied, both nervously and excited. “You will need to come into the office once a week for your injections,” the doctor pulled a small case from his desk drawer. Hunter couldn’t help but notice the odd dog pup mask in the drawer beside the case. The doctor noticed Hunter looking at the mask and smiled, “we have to record the injections and some of our subjects like the anonymity of wearing the mask. Its lightheartedness makes them relax as well. Do you prefer to wear it?” Hunter laughed, “sure.” Dr. Stone help him pull the tight hooded mask over his head. Hunter looked at himself in a mirror and oddly found it arousing with the dog face peering back at him. The doctor then proceeded to turn on the camera that was set up on a tripod in the middle of his elegant decorated office. He then open the case and took out a small vial “Now pull down your shorts and underwear and bend over the desk,” the doctor instructed as he filled up the syringe from a vial. Dr. Stone paused as he couldn’t resist admiring the two firm glutes facing him. He then gently touched it. His right hand lingering on the meaty left cheeks as he presses the needle against the firm flesh. The doctor squeezed the muscles as the needle broke the flawless skin and he then injected the clear serum into the buttocks. His hand still lingered on Hunter’s ass even after he pulled the needle out. Hunter remained bent over. At first he felt no difference, then he started to get rock hard. To Hunter’s horror, he realized that he was being turned on by the older man’s touch. Hunter turned bright red in embarrassment. Stone was smirking as he gently rubbed the boy’s plump ass. He then gave it a firm slap, causing Hunter to jump. “It will be all for now. You can pull up your underwear and shorts now,” Dr. Stone continued to smile. Hunter was embarrassed as he realized he was still bent over with his shorts down. He hurried to pull his briefs and shorts back up his legs and over his butt. After he left the science hall of the university, Hunter went straight to the gym. He worked out for two hours lifting and then 30 minutes of cardio, as he was instructed to. Hunter felt wonderful. He was full of energy, his muscles were pumped, and veins were large and full. After he finished his workout he started to feel so fucking horny. His cock grew rock hard in the gym locker room, so he had to hide his cock in his thin shorts as he hurried to his favorite shower stall to jackoff. He came harder than normally and he even had to bite his lips to keep himself from crying out. After he showered off his cum and changed back into his workout clothes, he left the gym and took the subway home. As he sat on the train, he couldn’t resist checking out his muscles. His arms were still pumped as if he had just finished curling them. He could even see the traces of long, thick veins that ran up truly bluffed up bodybuilders’ arms. Hunter has been trying to get those veins in his arms for a long time. He looked across the aisle of the train and noticed a man staring at him. The man had a briefcase over his lap, but Hunter noticed the man’s right hand was underneath the briefcase. Hunter’s eyes met the man’s eyes, and the man smiled. The muscle boy turned red again as it became obvious that the stranger was stroking himself under the briefcase while checking him out. Hunter started to get hard again. His cock pressed against his briefs and the thin workout shorts did nothing to hide his hardon. He pulled his gym bag onto his lap to try to cover it. He was so relieved when the train reached his stop and he hurried out of the subway car. When he got home to his tiny apartment, he pulled off his clothes and jerked off feverishly. Dr. Stone gave him a link to download several recorded files and instructed him to listen to them every night before bed. He downloaded the files and before falling to sleep he put his earbuds into his ears and activated the files. All he could hear was a low hum and static, however, he quickly fell into a deep sleep. As he slept he began to dream that he followed the man, from the train, off the train and into the dirty bathroom of the subway stop. It felt so real that Hunter could almost feel the man’s hands stripping him and exploring his thick muscles. His muscles were bigger then they are now. They were huge and shredded. However, despite how huge his muscles were in his dream, the older weaker man pushed him down on his knees and fucked his mouth. When the man was about to cum, he pulled out of the muscle boy’s mouth and sprayed his cum over Hunter’s face. Next he dreamed he was getting fucked by Professor Stone. Hunter was wearing the pup mask over his handsome face, as the doctor bent him over the desk as if he was about to get his injections. Instead of injecting the syringe into Hunter's huge ass, Stone pushed his massive cock up the boy’s hole. The doctor fucked him hard and deep until he fucked Hunter’s cum right out of him. When Hunter woke the next morning, he was covered in cum. He was humiliated that he had came in his sleep. As the week went by Hunter already saw results and felt stronger. He also however found it harder to concentrate on anything other then working out and sex. Hunter even failed an easy test in one of his favorite subjects at school. He knew the subject and should have ace it. Hunter felt horny all of the time. After an intense workout he would start to feel an itch that started deep inside his ass and caused his cock to get rock hard. To be continued
