The BioLab

To Johns surprise, behind that door, he met nothing but a longish hallway. Well, the hallway itself was not much of a surprise but he somehow expected there to be, well, guards? Or at least someone. Maybe he was actually just imagining all of this after all... Sure the girl at the reception may have been confused, but this could have a lot of reasons, right?

The doors all had a little sign next to them. Most of them simply displayed a room number. Some of them also had one or two names on them. And a few actually told him a little bit about what to expect inside. Supply closet? Well no thanks. IT and App development. Here he would have to go if he actually did have a problem with the app he assumed.

This looked more promising. Upper management, John read on a sign pointing to a staircase that lead up another story. Just as he was about to head in that direction, however, he heard the click of a door opening and closing behind him. Slowly he turned around. There was not really any point in doing it slowly, it's not that this would make him harder to see as the only person in this otherwise empty hallway.

Out of a door on the other side that was labeled 'BioLab' stepped a nerdy-looking black girl in a lab coat and a large pair of glasses. Under the coat, John could not overlook her rather impressive cleavage.

She was staring at him in disbelief. He was staring back at her, feeling caught. They both blinked. Nothing happened for a full 5 seconds except an awkward and yet tense silence.

After a rather long time had passed John got the impression that something dawned on her face. "Ohhhh.... are you here because of the new samples we need?" John had not the faintest idea what she was talking about, but he did not come this far to be thrown out now. "Erm.. yes. Samples, sure."

She smiled at him in disbelief. "Huh. Who would have thought that it would be delivered... well, the old-fashioned way. Not that I am complaining." She grinned and was about to push the door she had just left back open. She hesitated for a moment, turned, and asked him "Oh erm... you have signed all the usual paperwork I assume?"

"Erm.. yes I did that on my way in." John made up. "Good. Not that I get into trouble here." As she lead him in, John could see a small name tag on her coat. Tanya, she was called. While Tanya led him through a sterile-looking hallway she got a bit more chatty "We are so happy to have you here. Well, I am. Actually, none of my colleagues is here today. I did not even know you were coming, must have been some strange mixup... Anyway, you can imagine how happy we are to get a new sample, considering how rare of a commodity it is."

John got a first suspicion of what she may be talking about. A rare commodity, huh? The old-fashioned way? Tanya went on "Normally, as I said, these days we just get the stuff in a small glass tube on ice or something similar. But we do still have our old extraction room. You know when I started this job I always dreamed of a scenario like this, haha. I mean sure it was rather unlikely I knew that of course, but hey who has been proven wrong now, huh?"

Tanya pushed open the door to a very strange-looking room. On the one half, it looked like a state-of-the-art lab, or at least John suspected it was state of the art, he had no idea about what any of these machines were supposed to do in detail. The other half though was taken up by a large bed. A strange combination surely. But further confirming his suspicion.

"So" Tanya turned to him now "The choice of course is up to you, but in my professional opinion, we get the best results by using a..." with a surprisingly quick motion she manages to somehow pull off her dress and stand in front of him in only her open white lab coat, not even trying to cover up her full black boobs. "... more natural method of extraction."

Well... being trapped in a strange research facility could have gone a lot worse, John supposed. "Let us get you a sample then" John said and walked up to Tanya, starting to squeeze her heavy tits. Her eyes looked up in his as she said, with surprising confidence "I will make sure to unleash your full potential."

With that, her hands shot forward to his balls. John had no idea where she learned what she did then, or what she even did. Not only did it feel pretty good, but he could actually feel a load building up in m him already. Not that he was already about to cum but it just felt like somehow, it would be more than usual this time. After a bit, she let go of him again. "Now all you have to do is get your hormone levels to rise." The last part, she added in a seductive whisper "In any way you see fit."

John gave her a sudden push and Tanya fell over backwards onto the bed. He was on top of her immediately. With a mad grunt, John groped for her big boobs and buried his cock right in there. But fucking her tits was not enough. He moved up to shove it deep in her face. But even though he made her glasses fall off with his mighty thrusts, it was not enough. He knew what he had to do. He knew from the moment he saw her.

John roughly turned Tanya over and with a gleeful squeal, she was now on all fours, sticking up her big black ass. John quickly slid the lab coat over it and exposed it in all its beauty. A beauty he was about to tear in half with his rock-hard cock now. John grunted Tanya screamed. Somehow, she managed to tell him to warn her before he was done. She had a piece of equipment in one hand, a long tube-like thing with a contained at the end.

John however was not quite done. He did not pass up the opportunity to go back and forth between her two tight holes several times. After several more minutes, a quivering Tanya was kneeling in front of him as she milked every last drop of cum out of him, one hand guiding the tube contraption, the other massaging his balls again. John had never seen himself cum quite this much.
