Ella was in a state of panic after she entered the lab that morning. She distinctly remembered putting the sperm sample in the cooler the day before. Instead it had been sitting on the counter all night, at room temperature, ruined. At this point, she could either take the blame for the testing delay, or she could find another cum sample as quickly as possible.
After freaking out for a moment, she managed to compose herself.
Ella's mother, a lead researcher, had pulled some strings to get her this position. Her older brother worked there also. Failure would bring shame to the family! She needed fresh semen, and fast. But how? She quickly considered all possibilities and nothing seemed viable in such a short amount of time.
There was another option, however. A plan so shocking, she was amazed the idea had even crossed her mind. Though crazy, it was plausible and would solve her problem. No one in the lab would ever know of her screw-up.
Could she really pull it off? After thinking for a few more seconds, she found her resolve. It was necessary, and in the name of science, she would make it happen.
Ella put on her lab coat and placed a small beaker in her pocket. Walking casually through the facility felt surreal as she contemplated her immediate future. Would the next half hour haunt her for the rest of her life?
Her brother Jeff was trustworthy. Over the years, they had watched each other's back countless times. He was the perfect older brother: smart, patient and protective.
Most importantly, Jeff was a HUGE cummer. She discovered this having accidentally barged in on him a few times. Her brother could cum in spades. Not only was it high in volume, his cum was also high in quality. She could tell if he had recently masturbated by simply walking by his bedroom door and taking a whiff; the aroma was unmistakable. He was both potent and virile.
At this moment, Ella desperately needed his special skill and wondered if he would come through for her.
Ella also thought of her Mother's advice; 'If you ever need anything, just ask your brother. I've instructed him to help you whenever possible.'
This may not have been what Mom had in mind, but it would surely be enough for the much needed sample.
She arrived at his lab on the other side of the building. After making eye contact with Jeff, she silently summoned him by nodding her head towards the office in the corner of the large, sterile looking room. It wasn't completely private, but it was secluded enough for her top secret plan.
Once the office door was closed, she went straight to business.
"Jeffrey, I need to talk to you," she said, using his full name to convey the seriousness of the situation.
"What's going on?" he asked.
"Oh my god, I'm freaking out right now! I accidentally ruined the sperm sample we need for today's test!"
"Yikes. Well, it's not the end of the world. These things happen. People don't get fired for little slip-ups, if that's worrying you."
"I'm not worried about being fired," she said nervously. "I'm worried about our reputations since Mom got me this job."
Jeff thought for a moment. "Ok, relax. We need solutions. Any ideas?"
"Actually, yeah. I want to replace the sperm sample. But we need a healthy size sample to cover all the testing scheduled for today."
"How are you going to do that on short notice? Did you reach any of the regular donors?"
"Too much hassle," she said nervously. "If I contact them, then everyone will know of the mistake."
"Then who will produce the sample?"
Ella cleared her throat. "I was hoping-
you.
"
"Me?" he asked, taken completely aback.
"Jeffrey, I've seen your loads before. They're huge! If you give me a big enough sample, all of my problems will disappear. It'll be our secret and I'll owe you big time."
"How much do you need?" he asked, while pushing away the embarrassment in order to help his little sister.
Ella removed the small beaker from her pocket.
"This much," she said, pointing to the exact measurement scale.
He shook his head. "Guys can't just shoot massive loads at the drop of a hat. It's a bit more complicated than that."
"I know. I know. You need the right stimulation, both physically and mentally."
"Then you can see why it's a problem for me to fill that up on demand."
Ella took a deep breath. "Which is why I'm prepared to help you."
"How?" he questioned.
"I'll do
whatever
you need," she said suggestively. "You know what I'm talking about, so please don't make me say it. This is humiliating enough."
"Jesus," he sighed.
"You know I'm only asking because it's an extreme emergency."
"Honestly, it would better to just admit..."
She put a finger on her brother's lips. "Hush. Do you want me to suck your dick, or not?"
Her coarse words seemed to do the trick because Jeff's eyes lit up with excitement. Ella could see that her brother was now very interested (and possibly already erect). She moved her finger away so that he could speak.
"Are you sure?" he confirmed. "Right here? Right now?"
She nodded. "I'll suck your dick, but Mom can never know."
"This might be the best way."
"I'm glad we're on the same page. You're a lifesaver."
"Yes, but I can only do it on one condition," Jeff spoke haltingly.
"What? Getting a blowjob isn't enough?"
"No! I mean... yes! I'm very grateful. But... if you want a large quantity, there's something else I need."
She crossed her arms. "Just spit it out already- no pun intended."
He took a deep breath. "Do you mind if I talk dirty while it happens?"
"Talk dirty... as in..."
"Dirty sex talk," he confirmed. "While you perform fellatio on me."
She sighed, "Does it get you off in a big way?"
