Will had known that something wasn’t quite right with his body, how he was maturing – growing, specifically – for at least the last year. He started noticing things changing in ways that he thought were unusual since the summer after he graduated from high school; now it was a year later, and in his mind there was no doubt about it – things definitely weren’t right.
“That’s just not right,” he said, looking at his nude body in the full-length mirror in his room before he got dressed for the day. He wasn’t sure whether to be concerned about what he saw or happy as hell instead. He was leaning very strongly towards being happy as hell, because from what he’d heard, what was going on with him was a dream come true for most men.
“Honey, breakfast is almost ready, are you coming?” his mom, Judy, called from the kitchen.
“Yeah, Mom, I’ll be right there,” he called back. He took one more look in the mirror and then got dressed, putting on a pair of khaki cargo shorts, a black t-shirt, and his sandals. He never wore underwear in the summer, but this particular summer that wasn’t the only reason.
Judy was just putting the plates full of scrambled eggs and bacon on the table when her son came into the room. He was a very handsome young man, she thought, even though he was slight of frame and wore glasses. His dark hair was rich and full, his brown eyes simply beautiful, and when he smiled it melted her heart every time she saw it.
‘If only he was a bit more masculine and wasn’t so…geeky!’ she thought to herself as her son sat down at the table.
“Morning, Mom,” he said, picking up his fork and starting to eat.
“Good morning, honey,” she replied, doing the same. “Sleep okay?” she asked as she always did.
“Like a rock, as usual,” he replied. Will may have had his problems, but sleeping wasn’t one of them.
“Good! So what do you have planned for this beautiful Saturday in July?” she asked, curious.
“Oh, I don’t know, not much, really,” he replied. “Thought I might drive over and see Ethan for a while. I haven’t seen him since before he went on spring break; he was supposed to spend it at the beach with his mom, and I’m curious to see how that turned out,” he said. Ethan was his best friend from high school who was now attending college, and he lived close enough to his home to visit on a regular basis. Now he was home for the summer, and Will wanted to go see him.
“That’s a novel idea for spring break, a son spending it with his mother,” Judy replied, smiling. “He must love his mom very much,” she said, putting another forkful of eggs in her mouth.
“He does. He sprung for the entire trip, including the hotel. And he picked the most expensive hotel on the strip, too – ‘The Windjammer,'” he said.
“Oh, my, I’ve heard about that one; you’re right, it’s expensive, but from what I’ve heard it’s well worth it,” she replied.
“Well, anyhow, I thought I might drive over and see him, find out how his spring break went,” he said.
“Are you sorry you didn’t go to college this year, son?” Judy asked, genuinely concerned. Her son was smart, very smart, and she was a little surprised when he said that he wanted to take at least a year off from further schooling. He got a full-time job at the local computer shop, was making good money for a 19-year-old, and seemed happy about his choice to stay home.
‘If only he could get a girlfriend,’ Judy thought, looking over at her son as he ate his breakfast.
They ate in silence for the next few minutes, and when they had finished Will helped his mom clear the table and load the dishwasher. There were a few things she needed to wash by hand so Will sat down at the kitchen table while she was at the sink, trying to decide whether or not he should talk to his mom about his ‘problem.’
As he looked at his mom from behind washing dishes, he couldn’t help but wonder why there wasn’t a man in her life. His father had been killed in a car accident before he was born, so all Will knew of him was what his mom had told him. He suspected that his death soured her on getting involved with another man; from what she had told him about his father when he was growing up, Will Senior was the love of her life and she’d never love any other man again except for her son.
But if she ever decided to do that, she certainly was attractive enough for it. Judy was 5’5″ tall with sandy brown hair that she wore down to her shoulders, a very cute face with sparkling brown eyes, and a body that certainly qualified her as a ‘MILF.’ Judy had always taken care of herself, promptly losing the baby weight after he was born and keeping it off. She was slim, trim, and fit, with a moderate bustline and a simply killer ass that drove not only Will wild but most of the men around her, especially when she was wearing the skin-tight dark blue Spandex shorts that she was wearing now. She was wearing a white cropped sleeveless shirt to go with it, the perfect outfit for a July day. Will couldn’t help but smile as he watched his mom’s shapely butt wiggle as she washed dishes, noticing the absence of a panty line and wondering if she was wearing a thong or nothing at all.
Not only was his mom attractive, she was smart as hell, too. Judy had a PhD in chemistry and worked as a research scientist for a very prominent drug company, having played a major role in developing some of the latest cutting-edge drugs to treat everything from rashes to cancer. She was paid very, very well for her work, although Will had the idea that not even being that well off was making his mom as happy as he thought she could be. She had a private lab in a room on the lower level of the modest two-story house they lived in which she kept locked at all times. As long as they’d lived in that house Will had never seen the inside of that room, nor was he sure he wanted to. All he knew was that she spent a lot of time in there when she should have been out dating instead, and he thought that maybe this was her way of compensating for not being involved with a man.
Will watched her for another minute or so, finally making up his mind. He and his mom had always had the kind of relationship where they could talk to each other about anything and everything, so he finally decided to talk to her about his ‘problem.’
“Mom, can I talk to you about something?” he asked. His mom was just drying her hands, having finished washing the few dishes in the sink, and turned to face him as she did.
“Certainly, honey, you know that,” she replied, smiling. “What’s on your mind?” she asked.
“Well, I kinda have this…problem, I guess,” he said, not knowing how to say what he needed to say, especially considering where his problem was located. “I don’t know how else to describe it,” he said.
“Describe what, honey?” she asked, her voice soft, her hands clasped in front of her. He paused for a moment as he chose his words, still unsure of how to say it.
‘Oh, fuck it!’ he thought to himself, deciding to just come out and say it.
“I think my penis is abnormal,” he said, taking her by surprise and making her eyebrows go up.
“Abnormal how, Will?” she said, her interest rising dramatically now that she knew what he was talking about. Mentally she had just shifted from caring mom to evaluating scientist, although Will would never pick up on it.
“Well, it’s…it’s big, Mom,” he said, stuttering just a bit but looking her in the eyes as he continued. “And it’s not just my penis, it’s my testicles, too. I think they’re all bigger than they should be, a lot bigger,” he said.
Judy’s breath caught in her throat at his words, becoming very excited at what she was hearing.
‘Damn, it worked! It really worked!’ she thought to herself, suppressing a smile. Four long years of exhaustive research and experimentation was paying off!
“Big, you say,” Judy replied, the calculations running through her head, her brow furrowing just a little as she thought. “How big, honey?” she asked, a serious look on her face.
“I don’t know, really,” he replied, glancing down at his crotch as he sat at the table. “I never measured it, to be honest. I just know that it’s a lot bigger than it should be, and I’m kinda worried that something might be wrong down there, you know?” he said, the concern evident in his voice. “Also, I’m a lot…well, I get aroused a lot more often than I used to, and I mean a lot! And when that happens, all I can think of is taking care of it, if you know what I mean,” he said, blushing a little bit.
“Yes, honey, I know what you mean,” she replied.
‘Frequent and intense sexual arousal…that’s another sign that it’s working,’ she thought to herself.
“How long has this been going on?” she asked, making mental notes. Will thought for a moment before he replied.
“Since last summer, I think,” he said, thinking hard. “Yeah, it was right at the end of last summer when I started noticing that something was different. And since then it’s just gotten worse, if that’s the right word,” he said.
‘That’s about right,’ Judy thought to herself. ‘The first effects would have been noticeable thirty to forty-five days after the first dose, so the timeline is correct!’
“Bigger, you mean,” she said, correcting him.
“That, and it’s been happening more often, too – my getting aroused, that is,” he replied. “What’s going on, Mom? What’s wrong with me?” he asked, the concern evident in his voice. “I mean, I know guys my age get a lot of boners and all that, but this is ridiculous!” he said. She walked over to the table and pulled out a chair, sitting close to him and looking into his eyes as she spoke.
“There’s nothing wrong with you, honey, nothing at all,” she said, reaching out to put her hand on his knee, giving him her best smile. She held her hand there for a moment, then sat back and put her hands in her lap as she continued.
“I have something I need to tell you, Will, more of a confession, really,” she said, looking him in the eyes as she spoke. “You see, I know why these things are happening to you, because I’m responsible for them. I’m the one who caused it,” she said, hoping he wouldn’t be mad at her.
“You?” he asked, his eyebrows going up behind his horn-rimmed glasses. “How are you responsible for this?” he asked. Judy took a deep breath and said a quick prayer before answering.
“Well, honey, for the past four years I’ve been secretly working on a new drug in my lab here at home, and not even the company knows what I’m doing. I wanted to get it developed and fully tested with documented results before I presented it to them for further refinement and eventual marketing,” she explained.
“What kind of new drug?” he asked. “What does it do?”
“It’s a combination drug which treats erectile dysfunction while increasing both performance and growth of the male genitalia, allowing for increased endurance and enhanced production and expulsion of semen,” she explained. She could see that her choice of words and use of terms had only confused him, so she repeated herself in plain English.
“It gives men an erection, makes their penis grow bigger, lets them stay harder longer, and shoot more cum when they orgasm,” she said, sitting back and holding her breath while waiting for his reaction.
“Oh,” Will said, looking at her. He looked at her in silence for a few moments, making her very nervous, before speaking again.
“And you gave this new drug to me?” he said, perfectly calm.
“Yes, honey, I did,” she said, her voice soft.
“Without telling me?” he said, still calm.
“Yes,” she said, feeling the first pangs of guilt.
“How?”
“In your orange juice, or whatever you were drinking. It’s colorless, odorless, and tasteless, so you never knew it was there.”
“How often did you give it to me?”
“Once a week.”
“Oh.” He sat without moving, still looking at her, his face expressionless. After a few very tense moments he spoke again.
“Why didn’t you just ask me to take it, Mom?” he said, asking the one question that she was dreading the most.
“I didn’t want you to know you were taking anything; that way you wouldn’t be looking for something and maybe seeing things that weren’t there or weren’t happening. And when something did happen, you’d come to me and talk to me about it, giving your opinion which I would know to be genuine,” she explained. “Besides, I didn’t think you would have agreed if I had asked you. Would you?” she asked. Will thought for a moment before he replied.
“I’m not sure, really,” he said, his brow furrowing as he thought it over. “I mean, I love you and would do anything you wanted me to, but this…I dunno,” he said, looking into her eyes. “I guess it’s all a moot point now, because I took it, it works, and we’re talking about it, just like you wanted to happen” he said, showing a wisdom that surprised her for a young man of his youth. To say she was relieved was the understatement of the year. She reached out and held his hand as she replied, smiling.
“Thank you for not being mad, son, thank you so very much!” she said.
“You’re welcome, I guess,” he said, returning her smile. Now that the hard part was over, it was time to press on.
“The question now is, just how well is it working?” she said, looking at him.
“You mean…oh, that!” he said, realizing what she was talking about.
“Yes, that,” she replied.
“So I guess you wanna see for yourself, huh?” he asked.
“If you don’t mind,” she replied.
“Hey, you have to see it in order to evaluate the results, right?” he said; Judy just nodded. “Besides, it’s not like you’ve never seen one before, right?”
“Right,” she replied.
“Sure, why not?” he replied, shrugging his shoulders.
“Thank you, honey! Just give me a minute to go get a couple of things, okay? I’ll be right back!” she said, getting up and patting him on the hand. She turned around and nearly ran out of the kitchen before he had a chance to reply. She returned less than two minutes later with a small notebook and pencil in one hand and a small blue cloth tape measure in the other.
“Okay, I’m ready!” she said, sitting back down in her chair and putting the tape measure on the table, then opening her notebook. Will stood up and unfastened his shorts, then let them fall to land around his ankles. The tail of his t-shirt was covering his crotch, and when he lifted it up Judy’s eyes grew wide, her eyebrows going up and her mouth falling open in surprise.
Will’s cock was huge. Even fully flaccid it was nearly as long and as thick as an untreated penis, hanging down in front of him like a small firehose. She could see that his balls were bigger as well, proportionally bigger so that they matched the size of his cock.
“OH!” she gasped, surprised at the size of the young cock in front of her. “Oh, my! Wow!” she said, sounding more like a surprised woman than a scientist.
“It worked really good, then, huh, Mom?” Will asked, looking down at her as she looked at his cock.
“I’ll say! I mean, I expected it to be larger than average, but this! This is…this is amazing! Phenomenal! I never expected results like this!” she said, her eyes locked on his huge cock as she marveled over what she was seeing.
“I really need to measure it, okay, honey?” she asked, reaching over and picking up the tape measure, then holding it up for him to see.
“Sure, go ahead,” Will replied. Judy put the notebook on the table and then placed the end of the tape measure at the base of his cock, then unrolled it towards the head, holding the end in place with her thumb. She was astounded to find that her son’s cock measured 5.9 inches fully flaccid! She made a note of this in her notebook, then looped the tape measure around the shaft and pulled up the slack. Her mouth fell open at what she saw.
“Five point two inches,” she said, astounded. She wrote this down in her notebook, holding the tape measure in place around his shaft with one hand as she did. “Honey, you’re not going to believe this,” she said, looking at her notebook and making more notes as she spoke, “but your penis when it’s fully flaccid is the same size of an average untreated penis when it’s fully erect! This is just amazing!” she said, grinning, still scribbling in her notebook.
“Uh, Mom..” Will said, trying to get her attention.
“Yes, honey?” she said without looking up, still scribbling.
“That’s getting kind of tight,” he said. Judy turned her head to look, and her mouth fell open in surprise. His cock was getting hard, the shaft bulging out slightly above and below where the tape measure was wrapped.
“OH! I’m so sorry, honey, I got carried away!” she said, releasing the tape measure from around his shaft. She watched in amazement as his cock continued to get hard, growing longer and thicker right before her very eyes, rising up in front of him until the head was pointed up at the ceiling. His cock was fully erect in just over a minute, the veins clearly visible, the shaft bobbing slightly with the blood pumping through it. Judy had never seen a man get an erection that fast before, and it just blew her away – until she got her first good look at his balls and was astounded at how big they were. They hung down from under his cock, the ball sack stretched out, looking as heavy and as full as any pair of balls she’s ever seen.
“Oh…my…God!” she gasped in amazement, her hand coming up to her mouth.
“Is that good?” Will asked; his mom nodded as she replied, her eyes glued to his mammoth cock.
“Oh, it’s better than good! It’s beyond good! Way beyond good!” she said, looking up at him and grinning. “Now I need to see just how good, so that means I need to measure you again,” she said, her heart beating a little faster. She glanced over at the clock on the wall above the table and saw that the time was 8:24AM. She made a note of the time as she wanted to see just how long his erection would last.
“Yeah, I kinda figured you’d need to do that, so go ahead,” he replied. “It’s not going anywhere until I take care of it anyway, so there’s no rush,” he explained.
“Thank you, son!” she said, putting her pencil down and taking up the tape measure with both hands again. As she bent over and got closer to his cock to measure it, she got her first whiff of his musk. She always loved the smell of a man’s cock; it always excited her, and as she inhaled her son’s musk she felt a familiar twinging deep inside her pussy. She instinctively inhaled, taking a deep breath through her nose and getting her lungs full of his heady musk.
‘Mmmmmm, that smells so good!’ she thought to herself as she held one end of the tape measure at the base of his cock and ran it up the top of the shaft to the tip. For some reason she wasn’t as surprised this time as she was at first; maybe she was distracted by the unusually strong aroma of his musk, she wasn’t sure, but while she was a little surprised and very pleased at what she saw, she wasn’t as surprised as before.
“So how big is it, Mom?” Will asked, looking down at her.
“Ten point one inches!” she said, looking up at him and grinning. She reached over and made a quick notation in her notebook, then wrapped the tape measure around his shaft and pulled it snug.
“Nine point nine inches!” she said, again grinning as she made another notation in her notebook. “You’re going to make some fortunate young lady very happy with this monster cock, son!” she said, looking up at him and grinning. “If you don’t split her in half, that is!” she said, laughing.
