"Dr Chakwas! Dr Chakwas, help!" The voice from the intercom broke the peace and silence of the Normandy SR2's med-bay. Karin Chakwas, a doctor in question, despite her advanced age, immediately jumped on her feet. She could barely put her coat on when the door opened, and two figures entered the room. The incredibly tall, redheaded human was leaning onto the much smaller quarian and visibly limping.
"What happened?" Karin asked, unfastening commander Shepard's gloves and shoulder pads which fell onto the floor with a loud thud - years of peeling the armor off of wounded soldiers made her fingers move without hesitation.
"We were exploring a lab, and there was this weird flower. When Jane approached it, it released some kind of cloud onto her. She then grunted and bent in pain," Tali explained.
"I told you multiple times, commander: wear a helmet!" Dr. Chakwas scolded her patient, ignoring her tries to defend herself ("But I don't look half as a badass with that thing on!") "What about the flower?" She asked, taking off Shepard's breastplate.
"Mordin froze it and now is examining it at the research station," Tali answered, not without difficulties. Without most of her armor, Jane stood there with only her grey tank top on. The cloth revealed the commandor's muscular arms and tightly clung to her big breasts and impressive abs. The view was always making the quarian blush and stutter.
"That's probably nothing, it's ok now." Shepard waved her hand, but a grimace appeared on her pretty face. "Although I feel tight in my pants."
"Let's see it, then," Chakwas said and kneeled before the Spectre to take her graves off as well. The moment she did that, the three women could see a big bulge over one of the commander's legs. "So, that's the nothing, huh?" She allowed herself for a joke, after which she took Shepard's trousers off... and gasped.
Tali gasped as well, and it wasn't a reaction to the view of the commander's long, muscular legs. It wasn't even a reaction to the lack of panties, which revealed her bush and cunt. It was a reaction to what was sticking from between Jane's pussylips.
"You... you have a penis?" Tali asked as soon as she regained her breath. But truth be told, penis wasn't the proper word. It was a cock. A foot-long, thick, veined cock, with two heavy balls hanging underneath. "Are you a... a futa?"
"No, she's not," Karin answered, examining the new appendage, which twitched to her touch. "She was always normal down there. It must be the flower's spores."
"But I don't want it! I don't want a cock!" Shepard finally yelled. "Take it away, Doctor! Cut it off!"
"I don't have such an equipment here. But, there may be another option. You can try to fuck it away." Chakwas said matter-of-factly. "And before you ask, masturbation won't work. Only another person's touch. That's as much psychological as physical."
"I will do that," Tali said after a moment of silence. She had a crush on the commander for a long time and even fantasized about getting physical with her. She had to try, now that the opportunity occurred. Whether Jane had a pussy or a cock, didn't matter to the quarian. "Of course, penetration is off-limit at such short notice, but maybe a handjob would be enough?"
"Worth a try. Thank you, Tali," Jane replied, blushing almost as much as her friend. Dr Chakwas stepped aside while Shepard turned away from her for some privacy. Next, the quarian approached the commander and kneeled between her and the wall.
Here we go,
Tali thought to herself before raising her hands and grabbing Shepard's new cock. This was supposed to be her first handjob ever and she feared that she was going to be bad at it. Especially as the appendage was so big she could barely enclose it with both of her hands. But as soon as she got a good grip and started jerking, she instantly felt more confident.
"How does it feel like?" She asked when her hand flew up and down along the whole length of her friend's cock. Not waiting for the answer, she strengthened the hold and pulled the foreskin down, revealing the spongy head. It was dark pink, with the slit wide enough to sink a finger into it.
"That feels so good, Tal," Jane answered in a hoarse voice, her eyes partially closed. Despite the handjob just started, she already felt a strong sensation. She couldn't know it now, but as her cock grew from her clit, it was more vulnerable than a normal penis.
Hearing that, Tali only strengthened her grip and fastened her movement, jerking off Shepard earnestly. With the commander's cockhead now exposed and no foreskin in a way, the slit started leaking precum, which the quarian gathered and smeared along the shaft. With her gloved hands now slick with the opaque liquid, she could move more freely and she did just that.
"I can't believe it, Shepard," she said. "I'm jerking you cock!"
"Don't stop, Tali, please don't stop." The commander panted in response. "Jerk it away!"
That was the quarian's exact plan. Taking a solid grip, she continued masturbating her friend, getting more skillful with each passing second. Soon she got a good rhythm and her hands flew along the commander's cock with ease. Glistening with precum, the appendage looked powerful and beautiful at the same time, perfectly reflecting its owner, which only spurred Tali's horniness. Up and down, she moved her hands, the wet sounds filling the med bay.
"Oh, oh, Tali!" Shepard suddenly moaned louder than before and fell forward, exceeding her arms to not fall onto her friend. As a result, she slightly bent forward, supporting herself with her hands on the wall.
Startled by the commotion, Tali looked up, seeing her commander's face and upper body above herself. Being previously focused on her cock only, she didn't fully realize how much Shepard towered over her, and now it hit her hard. Then, all sensations she always felt seeing this 7 ft. tall, beautiful, and incredibly muscular woman became even enhanced by the tight space the engineer was in and a fat cock in her hands.
The commander must've felt something like that too, but the opposite, because her next words weren't a request - it was an order.
