The Muscle Lab by Mac Dr. Molly Harris deals with two thugs sent by a loan shark. Joe Conway hummed quietly to himself as he walked the short distance from his last class to the "Secret Laboratory" as he jokingly called the place where his good friend Lynn Martin worked. Joe was a student at Riverdale College majoring in computer science. Lynn, an old friend from high school, was heavy into Chemistry and had a part time job working as a lab assistant for Dr. Molly Harris. Dr. Harris was supposedly a brilliant research scientist. But because of her insistence on doing things her own way, Joe had heard that the college refused to sponsor her research. So she had set up a lab near the college and funded it with borrowed money. Joe often met Lynn after Friday night class to go out for a cup of coffee and some company. Joe never seemed to have any dates and was more interested in programming languages than in girls. Lynn was just as into chemistry as Joe was into computers. The fact that neither of them were what would be termed good looking didn't help matters. Actually, plain might be a good descriptive word for them. Lynn had shoulder length black hair that she constantly held clipped back on each side. She was 5' 4" tall with narrow shoulders and hips. She needed thick glasses to see and she never found time to exercise. Joe was a near perfect male counterpart to Lynn, but stood 5' 9" and had brown hair. They had always been good friends and they liked their relationship just like it was. Dr. Molly Harris was everything one would expect of a dedicated research scientist. She was mid-thirties with thick glasses and unkempt brown hair. Her usual dress was a white lab coat over a white blouse and polyester slacks. She was a little soft in the middle, and a little lacking on top. But she was, indeed, dedicated to her science, so much so that she had made some unwise business deals in order to get the funding she needed to continue her research into 'spontaneous cell regeneration.' As Joe approached the lab that Friday night, he could tell that something was terribly wrong. The front door had been forced open by someone or something with incredible strength. It was pushed in and broken and the door jam where the dead bolts had been locked was shattered as well. Joe picked his way through the mess and entered the lab. He saw his friend Lynn standing by the only table not turned over, raising a test tube to her lips. Before he could say anything, Lynn had drank the blue-ish liquid and set the tube down. "Hey Lynn!" Joe said, "What the hell happened here?" "Oh!" Lynn jumped as she turned to see her friend. "Oh, Joe, thank god it's you! You scared me half out of my wits!" Joe walked over to his friend as she slumped down on the floor next to the sturdy lab table, "Sorry. Are you alright? Where's Dr. Harris? Aren't those her glasses? What happened here? It looks like there was a small war in here." "Whoa ... slow down," said Lynn, as she held her head, "I'm okay ... I have no idea where Molly is ... yeah, those are her glasses - but I doubt she needs them anymore ... and it's a long story about what happened to the lab." "Well," Joe said, "I've got all night and I'm all ears." "Yeah ... I might as well tell you." Lynn said as she looked at her friend, "Besides, if you hang around here much longer, you'll find out anyway." Now Joe was doubly curious. "Well, Molly and I were running some tests on a new formula," Lynn began her story. "She had found a compound that looked really good. It seemed to be doing everything that she had expected and maybe even more. So we were started up a computer analysis of the stuff. We use a computer to simulate what would happen to a real person..." Joe interrupted, "Hello? Remember me? I wrote that program for you, so you guys could speed up the testing process." "Oh ... yeah" Lynn shook her head, "I guess I'm a little scattered right now. I'll try to focus. Any way, we were about done with the run when all of a sudden there was like an explosion and the door burst in. Turns out it wasn't an explosion, it was this really huge guy and he had just shattered the door busting it in. He was followed by this really slimy little guy." "The slimy guy looks around the lab and says something to Doc about having to pay back the money she borrowed. I guess she got a loan from some local loan shark to pay for all this equipment and was a little late paying it back. So Doc starts talking to the guy, trying to get him to wait for a while. But the twerp says 'No way' and then tells the huge guy, he called him 'Tiny', to start trashing the place. 'Tiny'! The guy is probably 6' 6" and weighs about as much as a rhino. "Well, that's when Doc starts losing it. She starts screaming about if they ruin her stuff, she'll never be able to pay. Then she grabs the little guy to get his attention, but he smacks her so hard That she flew across the lab and landed behind a table. "I ran over to help her up. But she pulled me down and whispered, 'Did the computer finish running the tests?' I couldn't believe that she was interested in that at a time like this. Still, I checked the monitor and told her what the results were. Then she stood up slowly, carefully picked up a beaker filled with the formula and drank it all in one quick gulp! I said, "Doc, what are you doing? That stuff might kill you!' But she just clenched her teeth and said, 'Sometimes you just have to trust your scientific intuition, and go for it.' "Well, pretty soon her whole body began to shake, her muscles were tightening, like they were convulsing or something. She doubled over and I grabbed hold of her to support her. All of a sudden, I could feel her body starting to change, like it was growing, right in my hands. Her muscles began to get harder and harder. I was holding her arms and felt them go from soft and small to larger and harder. Soon her arms were so big, I ... I couldn't hold on to them. "Her shaking stopped and she began to stand up. She looked taller than before and a whole lot ... bigger! I was standing behind her, and I saw her lab coat, that was usually two sizes too big, begin to fill out, then start to stretch. Then I heard the threads start snapping and the back of her coat and shirt slowly ripped open! She was growing so tremendously fast! I could see incredibly thick muscles forming along her spine and rippling outward, like huge bumps pushing against what was left of her shirt. Her legs were growing so much that they burst open her pants. And then her feet ripped out of her shoes. "Then she turned around and ripped open her shirt with her hands and my god, her boobs came spilling out followed by huge, thick chest muscles. She raised both hands and flexed her arms, and I'm not kidding Joe, her biceps tore through her sleeves like two mountains! Then she tore off what was left of her clothes and tossed them aside. She looked magnificent! She was easily six inches taller with muscles on top of muscles. She was practically radiating power! "Then she says, 'Wait here, I'll handle these two.' She walks over behind the two slime balls, who didn't see a thing because we were over in a corner and they were really getting into this destruction thing. Doc grabs the little guy by his coat and flings him ... across the lab! I mean the guy literally flew thirty feet through the air! He crashed into a wall and slumped to the floor. And Doc just stood there with this funny look on her face. I guess she didn't know her own strength and was shocked at how strong she had become! But Tiny wasn't shocked. He lowered his shoulder and charged at Doc. He must have caught her off guard because he pushed her into a wall and it looked like he knocked the wind out of her. "But Doc shook it off and came up hard with a knee in the guy's face, then landed a couple of really hard shots to his stomach. Then she knocked him down with a crushing blow to the head. She just stood over him as he slowly got to his feet. But all of a sudden he jumps up and smashes his big fist right into her boob. Man, you could see the pain on Doc's face. she retreated a ways and he came after her again. "This time, though, she was mad, and she brought her legs into the battle. She connected with a couple of side kicks into his stomach that stopped him cold. I bet she could snap a telephone pole with those legs, they're monstrous! Then she puts everything into one last kick to his head, and Tiny spins around and goes down. "Doc turned around and started walking back towards me, when suddenly, Tiny's on his feet again and he jumps on Doc's back. He wraps his huge arm around her neck and tries to snap it. But Doc calmly reaches up and grabs Tiny's wrist and hand. Then I hear something that sounds like bones cracking and Doc slowly peels Tiny's arm off her. Tiny is gritting his teeth and crying in pain as Doc bears down on his hand. Now she's really mad! She continues to crush him with one hand and then cocks the other arm back. I could see all of her muscles in her arm and back and legs tense up and grow really huge. She says, 'Say goodnight, Tiny.' and lets go with all of her strength in that one punch. Well, I told you this guy was big, right? Must be 300 pounds easy. That punch lifted him off the floor and sent him flying at least ten feet. That time, Tiny stayed down. "By the time that Doc finished with Tiny, the other guy had gotten up and was holding a gun to my head, threatening to blow me away. Doc just sighed and then I saw her leg muscles tense. Before we knew it, she was flying through the air towards us. She did a perfect somersault and landed with her legs wrapped around the little guy's head. As they hit the floor, she snatched the gun out of his hand and ... I still can't believe this ... she bent it in two, just like Superguy does in the comics. Meanwhile the poor guy's got his face plastered against her muff and he's screaming and punching her legs as hard as he can. But her legs were so pumped up that I could hardly even see the guy's head, and his punches were just bouncing off of her huge, hard legs. Then Doc flexes those monster legs and pretty soon the guy stops moving and goes limp." Lynn finished her story and then sat back against the table. Her body began to shake slightly and she clenched her teeth. "My god!," Joe exclaimed, "It's all so unbelievable! Where's Doc and where are the two thugs now?" "Doc picked them up," Lynn continued, beginning to feel a stirring inside, "and threw them over her shoulders. She said she was going to pay her loan shark a visit. And who says that doctors don't make housecalls ... any ... more ..." Her voice trailed off as she doubled over. "Lynn?" Joe held his friend by the shoulder, "Are you okay? Wait a minute! That stuff you were drinking when I came in, it's ... it's ..." "The formula," Lynn finished. "I mixed up some more of the ... formula ..." Lynn stopped shaking. "I was tired of being ... small ... and weak ..." Lynn was dressed in a T-shirt and jeans and Joe could see something was happening to her. He felt her shoulders begin to get harder and larger. Lynn sat up and turned to face Joe. "When I saw what happened to Molly tonight, I knew," she closed her eyes and tensed her chest muscles, stretching her shirt across her swelling breasts, "that's what I had wanted all my life. I wanted to be big," her jeans began to pop at the seams, "and strong," her shirt began to rip down the back, "and powerful!" Lynn stood and clenched her fists. Her expanding biceps tore through her sleeves and her boobs ripped open the front of her T-shirt. "YES!!" she shouted as she tore off her shirt and ripped her jeans from her waist. Joe could not believe his eyes. He was speechless. Lynn was taller, at least a half a foot taller, but her muscles! He couldn't begin to fathom the size and thickness of the muscles on his friend's once skinny body! Without thinking, Joe instinctively reached out and started feeling Lynn's incredible body. "Oh god, Lynn," he muttered as he stroked her bulging biceps and tremendous triceps, "is this really happening? Is this really you?" "That's right, bud." Lynn smiled as she flexed her arm. Joe's two hands couldn't even begin to reach around her rock hard bicep. "One hundred percent female muscle! And I'm dying to show you what it feels like." With that, the new super woman picked up Joe by his waist and hoisted him in the air. "Geez Joe, have you been losing weight? You feel as light as a feather!" Joe looked down at his friend in astonishment, not only from being practically thrown into the air by her, but also by the way her boobs had exploded in size. Her double D tits, backed by her thick pecs, made for quite a show from his perspective! Lynn cupped Joe's ass in one mighty hand and began to curl him, "How much do you really weigh, Joe? About 160 pounds, right? It feels like I'm lifting about 3 pounds. I could keep this up for hours!" Meanwhile, Joe was balancing himself by holding on to (as best he could) Lynn's volleyball sized shoulder. And at the same time he was finding that he was getting really turned on! The more he felt her huge, hard muscles, ran his fingers across the deep striations, the harder he became until he felt like he was ready to burst! He had never been this hard in all of his life. Of course, no woman had ever turned him on like Lynn was either. There was something so sexy about her huge powerful muscles, her bountiful breasts, the healthy glow that she exuded. Then Lynn took Joe by the waist again and placed him between her legs. Slowly she started flexing her mammoth thighs as she squeezed Joe's rib cage. Joe looked in awe as gigantic mounds of muscles burst from her legs, outlined by deep separations. Soon, though, the pain from her scissors grew, and Joe began to try to pry open Lynn's legs. Lynn ignored Joe's desperate efforts. She was busy felling her pumped up bicep and marveling at it's size and hardness. "God, Joe, you just can't believe what this feels like!" "I'm getting ... a pretty clear ... picture ..." squawked Joe as he hammered with his fists on Lynn's legs, trying to free himself. "Could you ... ease up ... a little?" "Oh, sorry Joe, I guess I got a little carried away." Lynn dropped Joe to the floor. "Are you alright? I hope I didn't hurt you. It's just that it feels so ... so wonderful!" Lynn stood over Joe and struck an impressive double-bicep pose that would have brought the house down at any bodybuilding competition. "Nice. Good muscle size, great definition, nice symmetry." Joe looked up from the floor towards the door. There was Dr. Harris standing at the doorway, no, filling the doorway! Her hair was wild and windblown from running and her smile glowed with power. As she walked toward them, Joe couldn't believe his eyes. She was even bigger than Lynn. Her arms were at least as big as his waist and her monster thighs bulged with each step. Her boobs were so round and firm, they hardly moved as she walked up to Joe and picked him up with one finger. She held him in front of her inch long nipples that topped off what Joe thought to be the largest natural breasts he had seen outside of his comic books. "So you decided to join me, eh Lynn?" said Molly, "And what shall we do with you , Joe? I see that Lynn has already given you a little taste of what our new bodies are capable of." Joe was coming closer and closer to an explosion in his pants as he dangled by Doc's finger and stared into her nipples. "I don't want word of this to get out just yet." Molly continued, "Do you think you can keep this a secret, Joe? We could make it worth your while..." To emphasize her point, Doc flexed her other arm. As Joe watched her football sized bicep take shape, he could take no more. His cock burst forth a stream of semen that seemed like it would never end and then, mercifully, he passed out. The next few weeks were busy ones around the lab. The two women, thanks to their newly developed powers, were able to clean things up quickly and get back to work. The loan shark never bothered them again, and was pleased when money from some of Dr. Harris' other discovers started flowing in. Dr. Harris outfitted a major portion of the lab with super heavy-duty exercise equipment. She was interested in finding out if the two of them might be able to actually increase their already prodigious strength. Joe stayed on as a loyal employee. He maintained the computers and the exercise equipment. If he did a good job, Lynn and Doc would reward him by letting him watch them workout and giving them rub downs afterwards. But if he screwed up ... well, lets just say that the headaches would last for days!
