Son needs to cum in her mouth– urgently!

Dr. Maria Ramirez was in a serious bind. Due to a technical error, a coolant hadn’t been activated properly, which resulted in several vials of sperm samples becoming unusable for research purposes.

One of the new medical assistants had forgotten to use proper procedures with the equipment. In the end, she was the lab manager, and checking to ensure all the equipment was properly working was her responsibility.

Making matters even more difficult, she was being considered for the soon-to-be vacant spot of Head of Research and Development. She’d be one of a handful of women to have ever held that title, and the only Latina.

Failure wasn’t an option.

The research was set to begin at exactly 10 a.m. sharp. An hour away. Canceling the session was out of the question. She could settle for using one vial of a man’s cum. The only issue was, how would she get it? It was too late to contact a male research subject because they all had jobs during the day.

That meant she needed someone in the building to donate a sample. As she thought of who to ask, hesitation crept in. This was uncharacteristic of her. Maria was never a choker. But asking an underling to jerk off in a plastic cup was a bridge too far.

A thought came to mind.

It may not be politically correct, or even appropriate, but it was a solid plan nonetheless. There was one male in this building who was young, hormonal, beaming with testosterone… and most importantly… could keep a secret from everyone else.

With the clock ticking, she made up her mind. Before leaving her office, she grabbed an empty vial and cap, tucked it into her lab coat pocket, then headed to the floor below.


Maria saw him organizing lab materials in the supply cabinet, then she approached him. There were others in the lab and they had just finished their work. She was certain no one would mind if she temporarily stole him away.

“Can I talk to you for a second?” she asked, touching George’s shoulder to get his attention.

He turned to her. “Sure, let me take care of this real quick.”

George finished his duty and they went down to the hallway. A few months ago, she pulled some strings and gotten him this internship.

“I need a favor,” she said.

“What is it, mom?”

This was going to be a lot harder than she thought. But she decided the best approach was to be blunt. Especially since this was for science.

“There was an error with our sperm samples,” Maria explained. “They’ve become unusable and I’ll have to get another sample. My promotion depends on getting this done.”

“They’ll understand, I’m sure. I mean, why did this happen? It wasn’t your fault, was it?”

She shook her head. “I don’t make mistakes. What’s important is, I’ll need another sample to proceed.”

“Why are you telling me? I’m kind of busy here.”

Maria took a deep breath. “I’ve already told your supervisors that I’m borrowing you for the next half hour. Think of this as an extra break time.”

“Now I’m getting confused.”

“I want a sperm sample from you,” she said in a low voice, to make sure no one else heard them.


George’s voice turned louder than expected, just as two doctors walked down the hall. Everyone in the research department knew that they were mother and son. As far as Maria was concerned, this was classified. Her reputation would be ruined if people found out that she asked George to do something like this.

She took her son by the arm and led him to an office. The office belonged to another manager in research. She closed the door to get a moment of privacy. Then she closed the blinds for additional discretion.

“Look, this has to be done,” Maria said firmly. “And you’re the only candidate I have at this time.”

He gulped. “Me? Why me?”

“You do it all the time at home,” she said harshly. “And I know you won’t gossip about this. No one can ever know.”

Maria reached in her pocket and held out an empty vial.

“Jeez,” he sighed.

“You have 15 minutes. I’ll give you $500. If I get promoted at the end of the month, I’ll double it. Consider this part of your job. Now get started. No excuses.”

She handed him the vial and was prepared to leave.

“Wait,” he said.

“No excuses, George. I need this.”

“I can’t.”

Maria sharpened her eyes intensely. “Why not?”

“Because I… you know… I took care of things before we came here today.”

“You what!?”

She was shocked that her son already masturbated that morning, but the news should have been expected. Her son took extra long in the shower earlier and she even had to knock on the door a few times to hurry him up. Now, such a harmless thing was threatening to derail her medical research.

“What do you expect?” he shrugged, embarrassed. “It’s the only way I can concentrate at work.”

She thought for a moment. “You must have a high libido, right? I’m sure you can get it up again. Can’t you?”

“Maybe, but I took care of that 2 or 3 hours ago. It’ll be tough.”

Maria looked around the room. It pained her to do this to her friend, but she reached towards the desk and grabbed a picture frame of a fellow doctor with her husband at the beach. She was in a nice bikini. Maria showed the picture of the happily married couple to her son.

“Use this,” she said. “I know she’s your boss, but she’s also a very hot MILF. I’m sure this picture can give you an erection.”

George studied the picture for a second. “She’s pretty, but she’s not really my type.”

“What is your type?”

“You don’t want to know. Besides, that isn’t going to do much for me. Is there anything better?”

Maria knew he was referring to the collection of hardcore porn that was often provided to sperm donors. The problem was, it was far away, and they didn’t have much time.

There was, however, something far more feasible. It could be shown right away, and it would be guaranteed to give George an instant erection. Was she really that desperate? As she stood there thinking to herself, the answer was yes. She was really that desperate for a sperm sample.

Maria held open her lab coat to show her buttoned up shirt and knee-length skirt.

She had curves in all the right places and she knew that George would sometimes take sneaky peeks at her. She knew what George’s ‘type’ was. She saw her son’s internet browsing history before. He likes curvy girls, big tits, and he has a thing for ‘MILFs’ too.

“Pick one thing,” Maria sighed. “Top or bottom. I’ll open myself for you, then you can handle your business.”

His eyes widened in disbelief. “This must be a joke.”

“I never joke at work. This is important. Choose carefully, because this is the only time in your life where you’ll get this offer from me.”

“God,” he sighed. “This is really awkward.”

“I know you’re interested. Let’s get to the point. Top, bottom, or my luscious backside, which I know you often like to take peeks at.”

She watched her son blushing. She watched her son pause to think, looking over her body to analyze the options.

“I… ummm,” he stammered, “Let’s be honest, mom, you’re going to be mad with whatever I chose. You decide.”

Maria shrugged. “Fair enough. You’re right.”

She thought quickly. The obvious display was her ass. As far as asses go, she fit the stereotypical Latina billing. She also knew that her son was fond of asses. Plus it seemed like the least intrusive option.

Her breasts were also a good choice. Her boobs were nice, she thought. Large, with big nipples. The only problem was, George had seen them a few times, here and there, over the years. They might not get the job done properly, and it would be a major hassle to fix her bra and top.

That left her pussy. Thank God she shaved a few days ago. Ordinarily, she’d be furious if George had ever peeked at her pussy. Now, she almost felt compelled to do it. If she were honest with herself, the thought of torturing him with the sight of her pussy seemed amusing and arousing.

“Hold the vial,” she said, handing it to him. “Stand where you are.”

George held it and stood there.

Maria went to the desk and pushed a stack of papers to the side. Then she pulled her panties down and put it inside the pocket of her lab coat.

It was the moment of truth. She lifted her skirt and sat bare-assed on the desk. Finally, she spread her thighs and lifted the front of her skirt to expose her pussy.

Instantly, George’s eyes lit up. Oh, there was no mistake about it, the young man had wanted to see this for years. The sudden attention made Maria’s pink pussy wetter, despite the sense of shame she was also experiencing.

“I’ll rub myself,” she said. “You do the same. Keep your eyes on my pussy and masturbate into the vial. Please be quick.”

“Yes, mom… I mean… It’s so weird calling you ‘mom’ right now.”

“Then call me Dr. Ramirez,” she smiled, feeling excited by her flustered son. “We’re working, after all.”

“Right, Dr. Ramirez.”

He smiled back, and then he hesitantly unzipped himself. His cock was already semi-erect and it made Maria lick her lips.

True to her word, she placed her right hand on her labia and gently rubbed. Unlike her normal masturbation sessions, this wasn’t for her pleasure. This was for George’s arousal. It worked. He was loving this.

The more lustful George became, the more aroused Maria became as well. This was most unusual. She hadn’t been this aroused in years. She rubbed in slow, clockwise circles. She paid special attention to her swollen clit, too. Lips then clit. Back and forth. Her favorite technique.

She kept her eyes focused on her son. Oh goodness, his cock. She stared at it. So hard, so stiff. In truth, she now desired it. She wanted to laugh thinking she’d most likely fantasize about this cock later at night.

Suddenly, her phone beeped from inside her coat pocket. She reached inside to get it and signaled for her son to be quiet.

Maria answered her phone. “Yes… I know…Yes… I’m well aware of the issue… No, don’t cancel the research… I’ll have a new sample in a few minutes… Don’t ask me how… Yes, I’ll be right there.”

The call ended and Maria slipped her phone back inside her lab coat.

“You’ll need to hurry,” she said. “The sperm is needed soon and there’s a bunch of lab technicians freaking out that their old samples are unusable.”

George stroked faster. “I’m trying. I’m trying.”

“My pussy isn’t enough to make you cum?” she asked with an eyebrow raised.

“This is too much information, but I shot a big load this morning. I think I’m drained.”

It was a fair point. This is a rare instance when being a doctor and a mother don’t mix. Most women would quit. Most women wouldn’t have even come this far with their son. Dr. Ramirez, on the other hand, was in a league of her own.

With the clock ticking, her pussy drenched, and her son raging hard, there was only one logical solution.

“Lean against the wall,” she said as she got off the table and stood upright. “I’ll need to get hands-on.”

“Really? How?”

“A medical technique involving physical, mental, and fluids stimulation.”

“What does that mean?”

“I’ll give you a blowjob,” she answered curtly.

She was now inches away from her son’s stiff cock. It was gorgeous, she thought. She pushed the taboo from her mind and held the dick in her hand. The same hand that had rubbed her pussy only a minute ago. She stroked him, coating his cock with her pussy juice, and she felt him pulsing.

‘No tengo verguenza,’ she muttered to herself in Spanish.

Maria leaned forward and took the head of her son’s penis into her mouth. It felt so soft and warm. She took in more, moving her tongue along his erect manhood and sucking firmly. Then she went deeper, taking in most of his cock. She sucked hard, making slurping sounds, and brought it to the edge of her throat, the way men loved, and slowly worked the head.

“Fuck, mom,” he moaned.

She spit the cock out and slapped his thigh. “That’s Dr. Ramirez. We’re working, remember? Even if it’s technically a blowjob.”

“Yes, Doctor. God, don’t stop. You’re doing such a great job.”

She went back to sucking. She continued her expert blowjob. It was a surreal thrill. One that she’d be fantasizing about for years to come, if not the rest of her life. She used every trick in her blowjob repertoire; sucking, stroking, fondling, tongue action, and she even sucked his balls in between servicing his shaft.

The average man would have been defeated already. George was right. He had already cum, and it would be a challenge for him to shoot another big load.

So as Maria sucked his dick, she undid her entire top and removed it, exposing her huge tits and getting naked.

She went back to sucking and heard George moan. She felt his cock twitch in her mouth. It was working! She played with her nipple, twisting it with her fingertips to give her son a hardcore show. She knew George’s taste was explicit (thanks to the internet) so she held herself to a high standard to get him off.

Maria released her nipple and brought her hand down to her pussy to rub. As she masturbated and sucked, she looked upwards. Her son was mesmerized.

She knew he’d never look at her the same way again. Maybe she was fine with that. Maybe not. Whatever the case, she had never been so aroused in her life. She was a woman who had experienced great sex in the past. This topped everything.

It sent her to a climax, which was the natural course of things. As she remained on her knees, her legs trembled and her lower back felt weak. She kept on plunging her fingers in and out of her pussy while she sucked.

George’s eyes turned wide at the sight of his orgasmic, cock sucking mother. She knew he was even closer now. She felt him throb in her mouth.

“There you go,” she said, spitting out the cock. “You’re ready to ejaculate.”

She stroked him furiously with one hand, and with her other hand, she held the vial to the opening of his penis. Right on time. As she stroked, she watched cum shoot from the tip of his cock into the clear vial. It was a sight to behold. She was mesmerized by what she was seeing.

When the spurts slowed down, Maria just couldn’t help herself.

“This needs a taste test,” she fibbed. “It’s part of the process.”

Maria pulled the vial away and wrapped her lips around the head of the shaft. She gave a tight suction. Then she squeezed the softening cock from the base and extracted the cum remnants onto her tongue.

She stuck her tongue out, which was cum filled, so George could see. Then she swallowed with a deep gulp after closing her lips. Her son’s cum tasted sweeter than expected and she remembered that she served him a fruit smoothie that morning– something she’d probably have to do more often now.

She stuck her tongue out again to show that her tongue was clean. Then she blew him a kiss.

“That was for research purposes,” she blushed. “You passed the… umm… taste test. It’s a very important step, actually. Now get cleaned up. We have to go.”

“Yes, Dr. Ramirez.”

Maria put a cap on the vial to preserve the cum sample. Then she got dressed, making herself presentable once again. She needed to look flawless, as if this never happened.

“Have a great day,” she winked. “And thanks again for the sample.”

With great pride, she left the office and rushed towards the lab with a vial of her son’s cum. It was the most bizarre feeling, but she had immense pride that she was able to overcome any obstacle.

She handed her team the cum sample — and with fire in her beautiful eyes — it was time to work.
