Doctor Young jerks off in his lab

Doctor Young quickly ate the protein bars in the lift and then made his way to his lab. He had an urge to view more of the samples, maybe there was something there.

He managed to examine a couple of the samples, looking for an unknown something but he kept getting distracted. He was horny and needed release. He felt his cock grow hard, and fished it out. Pumping it like a teenager, needing a quick release to take the edge off so he could focus on his work. He ejaculated over his hand in less than a minute but his cock remained hard and erect. He noticed that the jizz... it had black flecks in it. His instinct was to panic, he must have contracted something, possibly something deadly. Some unknown disease unique to Mars yet something inside him quickly overrode that instinct, calmed him, something told him that everything was normal.

He resumed jerking off and was midstroke when the door opened. Doctor Chen, his supervisor, entered. She was another young, brilliant and beautiful woman on an offworld base of young, brilliant and beautiful people. Each individual had been chosen for their ability to contribute to the colonisation of a barren rock with the potential to sustain life. That ability included youth and virility.

Doctor Chen approached him as he sat hunched over his erection like a teenager caught by his mom, "How are you? Kabir contacted me to ask whether you were ok. You were asking for meat of all things. Look, it's ok if you're hungover, seriously, take the day off. The samples will still be here tomorrow."

Doctor Young remained hunched over but turned his head to glare at her, "the samples would still be here tomorrow" she'd said, as if his work didn't matter, as if he didn't matter, as if nothing he had ever done had ever mattered. They would all soon be dust after all. Humanity would wither and become extinct like all other species before them. He, like all of his species, were barely a molecule in the writing of the footnote of the saga that was the universe.

He clutched at his head as he glimpsed something in his mind, something greater would sweep them all away in a tidal wave of blood and horror.

Doctor Chen stepped back and covered her mouth as she looked at Doctor Young with concern, "Let's get you to a medic. You're obviously not well, you should have reported yourself at the first sign, you know we can't allow a disease in an enclosed environment like ours."

Ed shook his head. "I promise I'm fine, I just need something to eat and drink."

Doctor Chen noticed the jizz on his hand. "What the...." she stammered, shocked that in a modern work environment a male colleague would have the audacity to do such a disgusting activity after all the HR seminars and hypnotherapy they had undergone to suppress the male urge to do... that shameful thing.

Doctor Young stood up, his erect cock hanging out and covered in semen.

Doctor Chen turned her back to him, determined she would have him expelled outside for exposing himself to her without express notarised consent. She stepped towards the exit filled with righteous indignation but Doctor Young grabbed her from behind placing his hand over her mouth to stop her screaming.

His jizz covered hand.

Doctor Chen could taste his cum on her lips, she tried to spit it out. She tried to resist, to fight him but after some moments something changed within her.
