Ch.02: The Medical Examination

"Remind me why I'm here?" Joker asked a little impatiently. "I have a ship to fly. Every moment I'm not in the cockpit this stupid AI may try something."

"This 'stupid AI' can still hear you, Jeff. If anything, she can hear you even better here, just outside of the AI core," Dr. Chakwas said. "And technically, she can try something whether you're there or not."

"I know!" Joker wailed. "Anyway, I'm all for reunions, always crying at them. But if it's a one, what is he doing here? No offense."

"None taken," the salarian replied. "Although indeed, I'm also wondering why I am at this little gathering: all old friends and me. I'm not familiar with this custom."

The three friends - Joker, Dr. Chakwas, and Commander Jane Shepard - were sitting in the Normandy SR2's med bay where the latter gathered them. Accompanying them was Mordin Solus, a professor recently recruited on Omega. A space station being the galaxy's resident wretched hive of scum and villainy, coincidentally located in the same system as the mass relay leading to collectors' homeworld.

"I need your help, all of you," Shepard explained. She was standing in the middle of the room with arms crossed over her big boobs. Being 7 feet tall, she towered over the three other people. "I..." Her voice trembled. "I have this heavy weight on my chest and I really need to share it with someone."

"We're here for you," Chakwas said, gently touching Jane's elbow. "You can always count on us."

The elder doctor's maternal expression and kind smile immediately soothed the commander.

"Thank you." She smiled back. "I invited Mordin because my problem is of a medical nature. His scientific background may come in handy in addition to your physician experience."

"What's an emergency then?" Mordin asked. "Are you dying? No, had just been rebuilt. Caught a blight on Omega? No, it wasn't affecting humans and had already been cured. Scale-itch? No, too sexually attractive to resort to such a thing."

"Ugh, gross!" Joker commented after the last two sentences. Jane only smiled - she'd already gotten used to Mordin getting lost in his line of thoughts. She liked to listen to his fast-spoken rants.

"No, nothing like that," Shepard finally said, getting serious. "It's... well, maybe I'll just show you."

She then straightened up and reached for her belt; she unfastened it and unzipped her pants. Next, she took a deep breath and with one swift motion slid down both her cargo pants and boxers. The clothes bundled around her ankles, but no one in the room was looking there.

Because without her pants, Shepard's new cock came into view. It hung low between her legs, proudly presenting its length and girth, both dimensions impressive even when it was flaccid. Two huge balls rested underneath like a pair of lurking beasts.

All Shepard's companions had been looking at her cock with different expressions: Mordin with curiosity, Jeff with shock, and Karin with something that was hard to decipher.

"Holy shit, Commander!" Jeff exclaimed when he regained his breath. "You never said you have a dick! Even more, that you're packing! How are we common folks supposed to compete with THAT?!"

Shepard breathed out stealthily. She feared that her friends may react with disgust or repulsion. Joker's reaction - although humorous - was rather positive.

"It's not like that, Jeff," Dr. Chakwas said. Her voice sounded a little off, and her eyes were glued to the huge appendage. "I examined the commander multiple times, patched her up... She didn't have a penis."

"Correct. Originally I didn't," Jane confirmed. "But Cerberus gave me this thing when they rebuilt me."

"The question arises: why?" Mordin cut in. "To tease you? Makes no sense, they want your help. Stimulate production of testosterone? No need, you're already strong and assertive enough."

"The Illusive Man..." Jane gulped loudly. "Want me to 'produce a new line of humanity champions', as he put it."

"Forget what I said earlier. That is gross," Joker commented. "Why the fuck did you agree to work with him after that? We should cut it off right now!"

"We can't do that. Those colonies are still being abducted, countless lives are on the line." Chakwas said, this time trying to look everywhere but on Shepard's cock. Her grey eyes finally fell onto Shepard's green. "Thank you, Jane, for entrusting us with this. But I have a feeling it's not everything."

"No. And this is where Mordin fits in, " the commander replied. "I need you two to check me. Check... it." She pointed at the appendage. "A Cerberus' doctor said it's a fully functional penis. But I need to know if nothing extra was added."

"Like what?" Jeff asked.

"I don't know, something fucked up. Like, my sperm being toxic to aliens to prevent me from ever spilling it anywhere but into a human vagina or something like that."

"Yeah, he could do that, sick bastard," Joker said. "But, it's way above my pay grade, or my knowledge level. If you want porn with a futa, I can provide it. If you want to check one, well, I'd be a liability. Gonna get back to the cockpit."

"I'll also return to my lab," Mordin spoke. "Doctor Chakwas may give you a physical examination, and that requires privacy. When you have a sperm sample, bring it to me, I'm gonna check then."

Not wanting for the answer, the two men left the med bay.

"It seems we women are on our own now," Chakwas said reassuringly, putting her hand on Shepard's lower back. "Come on, let's get started."

For the next half an hour Dr. Chakwas thoroughly examined Shepard's cock. She looked at it from all angles and touched everywhere, looking for any oddities and irregularities. She also took its measurements, and then when the first awkward moment came.

"Your flaccid penis is 9 inches in length and 6 inches in girth, Commander," Karin said, confirming what EDI said earlier. "Now, let's see how big it is on erection. You can have erections, right?"

Jane blushed, hearing this question. During the entire examination, she felt a little aroused, but such a blatant, kind of sexual inquiry was on another level. The commander's cheeks were almost the same color as her hair now.

"Y-y-yes," she finally answered. "I... I wake up with a boner every day. It also gets hard when I see an attractive woman. And sometimes even without that, on completely random moments."

Karin giggled.

"It's what penises do." She allowed herself for a wink. "I need you to 'get boner' now. For a measurement," she reminded, showing off the measuring tape.

Jane knew what she had to do and, still blushing, reached for her cock. It's just a medical examination. Just an examination, she tried to remind herself when she grabbed her cock and stroked it a few times. She considered fantasizing a little to quicken her erection, but the erotism of the situation - jerking off in front of her friend and physician - proved to be enough. Her cock quickly grew to the maximum size and Jane let it go.

"Wow..." Karin couldn't stop herself. "I mean, hold. Hold it like that." She put the measuring tape into its intended use. "12 inches in length and... 9 inches in girth. That's an impressive size."

"Thanks, I guess," Shepard muttered. She still didn't feel ok with her dick, but with it being in the open for so long she began getting used to it. Also, her own reaction to its size was quite similar - she had no right to blame Chakwas for it.

"Anyway, now I need to take a penile swab," the doctor said. Seeing Jane's puzzled expression, she added: "I'm going to take this cotton bud and sample from your glans. For it, I need to pull back the foreskin, ok?" Either it was Shepard's imagination, or Chakwas' voice really stuttered?

"Whatever you need, doc," Jane confirmed and a second later felt Karin's gloved hand on her shaft. Taking a solid grip, the doctor pulled on the commander's foreskin until her dark pink-colored cockhead appeared in sight in all its glory. Shepard didn't know if her dick should be hard for it or not, but it chose the former on its own and she was in no power to change it.

The examination itself was rather quick and funny, as the cotton bud tickled the commander's exposed flesh. But the next words Chakwas spoke made Jane shiver in both nervousness and arousal.

"Now, for the next step, we need to get a sample of your sperm, Commander. "You want to do the deed yourself or prefer my help? Either way works for me," she asked with a hint that there, in fact, was the preferred way for her. But Shepard's conflicted emotions disallowed her to catch on it.

"Be my guest," she murmured as if fearing that Karin could read too much out of it. After all, the commander didn't really want the doctor to touch her cock again. Didn't want it at all.

Chakwas didn't take long before starting her ministrations. She squirted a considerable amount of lube onto her gloved palm and then grabbed Shepard's cock with it. Her fingers had no chance to close around the erect shaft and it made her hand tremble. This was the biggest, the girthiest, and the hardest dick she had ever seen, and now she was about to touch it in such an erotic matter - even if just for medical sampling.

So without further delay, she began jerking Jane off. Her hand moved from the base almost to the cockhead and then back. She did it deliberately slow, as if she wanted to get familiar with the organ. She felt every prominent vein under her palm, and a medical lube allowed her for a smooth grinding.

"How does it feel, Jane?" The doctor asked. "I need to know it for an examination, to check if your penis' nerves work as expected," she added quickly.

"It feels... good." Jane chose the safest, the tamest option from what she could come up with. Before now, she never even thought of masturbating. But from that point onward, she wasn't so sure she would keep it that way.

All of that because Chakwas' ministrations didn't feel good - they felt great! The medical gloves she was wearing were smooth and cold, which created a wonderful contrast against the veined, hot surface of her appendage. She wanted to close her eyes and allow her head to fall back, but she managed to keep her eyes on the doctor while holding onto the chair she was sitting on's arms.

Chakwas' expression was focused and determined, but inside she felt more aroused than ever before. The cock she was jerking was not just lovely in its own right but was also attached to the sexiest woman the doctor ever saw - despite being straight, she could appreciate the beauty. And this dick she was tending to was for sure beautiful!

So she continued her handjob with a fervor, going faster and faster with every minute. She was an elder woman, but still had enough energy to do her job, even if what she was doing now was the most unorthodox thing in her career. It's just a research. I'm just helping my friend, she repeatedly said to herself, but somewhere deep down she knew there was more to it than that.

And it was showing, although Shepard was too much focused on her own pleasure and conflicted emotions to even notice that. Chakwas was supposed to just jerk off her patient to the ejaculation but began exploring various ways and techniques instead. She was twisting her hand, attacking Jane's 12-inches cock from various angles and with ever-changing speed, bombarding her brain with all forms of stimulation.

"Still good?" Karin asked. She wanted to say something not only to ease the tense atmosphere but also to drown out the wet sound coming from her lubed hand moving on Jane's impressive dick.

"Oh yes! Keep going!" Shepard said, a little too enthusiastic. "I mean, if you keep doing that, I'll cum in no time. And we'll be able to give Mordin that sample."

Chakwas only smiled at that. It seemed that she still got it, even after all those years! But truth to be told, her hand became a little weary. After all, Shepard's hard shaft was 10 inches long and every movement took a considerable amount of effort (and time) from the elder woman.

So she shifted her position. Up to this point, she was standing next to the commander, but now she kneeled in front of her. Somehow, that position felt natural to what they were doing, even if this was just a medical service. That feeling only grew after Chakwas looked up at her patient and fully realized how much she was towering over her and how toned her muscles were. Spurred by the moment, she took her glove off and began jerking Jane's impressive length with her bare hand.

"Shit!" Shepard immediately felt the change and her hand squeezed the arms of the chair she was sitting on with so much force that their shape had got distorted! Chakwas' palm was surprisingly soft for a woman of her age, but still a little withered, which created a wonderful sensation on Jane's 12-inches cock. And the fact that there was now no latex between their bodies, felt extra erotic to the redhead commander.

Shepard's cock reacted to the naked touch as well. It became even harder than before, and her wide slit began leaking copious amounts of precum. Before the opaque liquid fell on the floor, the doctor managed to gather most of it with her free hand. As she had nothing to do with it, she just grabbed Shepard's dick with her second hand as well! This one is slick not with an artificial lube, but with a natural one!

"Aaahh!" This time Jane couldn't stop herself. She released a loud moan, and for a moment her head fell backward. Dr. Chakwas had two hands on Shepard's dick now and thanks to it could actually close her fingers around it, creating a more consistent feeling. The pleasure was twice as big as before! At least!

Shepard's reaction didn't bother Karin at all - it was anything, it made her only more aroused and her hands began moving on Jane's cock with greater ferocity. From the very base of the appendage to the edge of its crown, the doctor jerked her patient again and again. Her patient who was not only her patient, but one of her best friends too! And an amazingly sexy, tall, and muscular woman to that! All of it together made Karin feel dizzy and under that sensation, she ceased jerking the commander off.

In reaction, Jane looked at her with poorly masked need, her eyes silently begging the doctor to continue. The elder woman only smiled and to Shepard's utter shock and horniness, took the top of her medical uniform off, throwing it somewhere into the med bay.

"I don't want it to get dirty when you ejaculate," she explained, rationalizing it for the last two brain cells that even cared anymore. It felt completely reasonable for both now-lusty women, even if this was the exact point of having medical clothing in the first place. So much so that Shepard herself reached out and ripped Karin's simple white bra off, the cloth following in the top's footsteps, joining it somewhere in the room. Where, Jane didn't care at all.

Because with her bra off, dr. Chakwas was now kneeling in front of her fully topless. Her skin was wrinkled, and her tits sagged from age, but right now, half-naked in Normandy SR-2's med bay, to the commander she looked like the prettiest woman in the world.

Under Jane's appreciative look, the last barrier in Karin's mind snapped. It wasn't a medical examination anymore. It was sex. And if it was sex, there was only one thing she could do next. And she did exactly that.

She got close, opened her mouth, and took Shepard's cockhead it.

"OH FUCK!" The commander yelled. Karin's mouth felt so good on the exposed flesh of her cockhead! So hot and wet! It was just the first contact, but Jane immediately understood why some men loved getting blowjobs so much.

Karin didn't lose a bit and right away began blowing Shepard's cockhead earnestly. For now, she restricted herself to the crown alone, but she wasn't tame at all. She sucked the 2-inch-long tip like a lollipop while her tongue teased the slit - for the commander, it felt as if the doctor made out with her cock! At the same time, her hands didn't cease jerking the shaft, and Jane felt her entire dick being caressed by the elder woman's capable hands, mouth, and tongue.

It felt amazing! Much greater than the previous handjob!

But Karin didn't plan to stay on Jane's cockhead for eternity. That's why after a few minutes of blowing the crown alone she pushed forward, and more of Jane's impressive shaft began disappearing in her greedy, wide open (to accommodate a girth of 9 inches was a challenge for sure!) mouth. After swallowing every extra inch, she was withdrawing a little for a moment, but then went in again, pushing more and more of Shepard's new appendage between her lips.

"Don't stop, Karin, don't stop," Jane encouraged her doctor - probably for the first time ever calling her by her first name - and lightly stroked her grey hair as her lips moved back and forth on the redhead's impressive girth.

"Do you like it, Jane? Do you like when I blow your cock?" The elder woman asked, raising her head, but still jerking off Jane's shaft. The musky smell of the commander's appendage combined with the salty taste of her precum was driving her into a sexually charged haze.

"Yes, I love it, so please, get back to it," Shepard answered, assuming a little more dominant tone and gently pushing Chakwas' head toward her cock. The doctor allowed herself a smile before getting back to the interrupted activity.

Immediately she swallowed as much of Shepard's cock as before, taking around 4 inches of diamond-hard cock right into her mouth. She moved her tongue all around it, drenching it in her saliva, while her lips sealed around the wide shaft. She felt so full already, and that was just one-third of the entire length!

But she still wanted more, and that's why she pushed harder, mustering all of her strength to push more of Jane's cock into her mouth - she wanted to smell it, to taste it, to feel it as deep as possible. She breathed it, enjoying the musky scent, slashed her tongue around, relishing in the saltiness of the precum, and closed her lips around the girth, feeling every vein covering it against her flesh.

And her effort paid off and soon another inch slipped into her gullet. One more, and she already swallowed half of the impressive length in! It would be an achievement even for someone much younger, so she was really proud that despite her advanced age she still got it, she still could handle a cock and give its owner great pleasure.

Shepard's moans were evidence of that. She felt so great with her dick in her doctor's mouth! She never imagined herself having any kind of sex with Karin, but right then she just wished they would do that sooner. After a moment though, she pushed those thoughts away, focusing on the moment and enjoying Chakwas' current ministrations.

And they were about to get even better! Because with 6 inches of diamond-hard cock in her mouth, Chakwas felt that there was no more room in her mouth, that Jane's cock reached the back of her oral cavity, and its tip was already pushing against her gullet. But she decided that it couldn't be the end, that she still had some strength to give Shepard more.

So she pushed harder and harder, relaxing her gullet, and millimeter after millimeter, her muscles accepted the meaty yet incredibly hard invader and allowed its entry into a canal they were guarding. Chakwas' throat was much tighter than her mouth, and Shepard's moans became even louder when she experienced one of the greatest pleasures in her life - for the first time with her cock and not her pussy!

Inch after fat inch, Jane's dick sank deeper and deeper into Chakwas' mouth and gullet, massaged by the doctor's lips, tongue, and throat. 7 inches... She moved with determination, every millimeter stretching her muscles and sapping her strength... 8 inches... If not for her medical knowledge, she wouldn't be able to do it... 9 inches...

And she felt that she reached her limit - she couldn't push more cock into her throat. As proud she was for taking so much in, there was no possibility she could swallow more. She looked at Shepard with apologetic sight, but in return, she received only an expression of pleasure and admiration. That steeled her determination and she decided to accommodate the depth with intensity.

And she did exactly that - she began blowing Shepard's cock with even more fervor than before. After the last few minutes when she was tending to the commander's dick painfully slow, she was now pushing it in and out of her throat and mouth at lighting speed, again and again letting 3 inches of it slide against her gullet, massaging it with her muscles and slashing her tongue against 6 inches that moved inside her mouth.

The commander was no longer looking at Karin - instead, she was staring at the ceiling while both of her hands kept the doctor's head on her dick as if she feared that she would stop blowing her. And that was something she really didn't want, her earlier doubts pushed somewhere deep inside her mind. Suddenly, she realized that she was flexing her buttcheek to not cum too soon and prolong the bliss for as long as possible.

"Cum, Jane, cum for me!" Dr. Chakwas said, suddenly taking her mouth off of Shepard's cock. She was blowing it for half an hour or so, and the effort of it started getting to her. "I need your sperm, so give it to me!" She ordered before slamming 9 inches of the commander's dick past her greedy lips again.

And it was good that she'd done that - because hearing lust and need in Karin's voice triggered Jane's orgasm, clenched buttcheeks or not. She suddenly felt the heat originating in her balls and quickly climbing the impressive, 12-inches length of her cock. Her entire 9 inches girth shuddered when the sperm produced in her huge balls swam all the way to her slit and were shot from it by the spasm of her pulsing crown.

"AAAHH!" Jane yelled when her first dick-orgasm ever hit her, short-circuiting her brain. At the same time, Karin's eyes widened when she felt the first batch of semen hitting her throat with the strength of the firehose and the next coming right into her stomach. But she wanted to taste it. She needed to taste in.

So she withdrew until once again only Jane's cockhead remained in her mouth; which wasn't easy, as the organ was still twitching and pulsing, sending more and more semen in. Now, it began splashing on her tongue and she was able to fully taste its salty flavor. She gulped hard, trying to swallow everything Shepard was giving her, but it was impossible and soon the thick, white liquid was tickling from the corners of her mouth.

Only by pure chance, Karin's mind chose this exact moment to remind her why she and Shepard had oral sex in the first place - to get the commander's sperm sample for Mordin, who was supposed to check it for any 'traps' the Illusive Man could set up in Jane's new balls.

Not taking Shepard's cockhead out of her mouth - but having more and more trouble with swallowing her sperm in time - the doctor reached onto her desk and going blindly, found a test tube. Only then she took Jane's cock out of her mouth and aimed it at the item's opening, in the process being able to observe an impressive display of Shepard's ejaculations.

Even after filling the test tube completely, the commander was still cumming, this time splashing her semen everywhere on Karin's torso until it was completely covered in a thick white goo.

It took Shepard a few minutes to be able to control her body again. It wasn't the biggest orgasm in her life (certainly one of them though), but the first with a cock and not a pussy, so she wasn't ready for the unique sensation her new appendage would bring her.

When the commander looked around, she immediately noticed two things. One, her 12-inches cock was still hard, even after cumming in buckets. Two, dr. Chakwas was kneeling before her, massaging Jane's sperm into her sagging tits and a little protruding belly.

"It's good for the skin, you know," she said, smiling with a smile only a woman who just made a cock ejaculate could conjure. "And you'd provided me with so much."

Shepard smiled as well, but the moment later the realization hit her: she just had sex with her friend and doctor! Oral sex only, but sex nevertheless! With her cock! With her cock she was supposed to keep in her pants! She enjoyed it, she couldn't and wouldn't deny it. But now, with a post-nut clarity and without a cock in someone's wet and hot mouth, she felt ashamed of herself.

"It was a mistake. It, not you," Jane said, a panic in her voice. "You were amazing, and I'll never forget how you made me feel. But, that wasn't supposed to happen."

Karin's happy expression turned into a serious one, but there was no hate in her eyes. She touched Jane's cheek with a hand that was still sticky from the goo and smelled of sex.

"I don't think so. I understand you, but I don't share those feelings," she said. "But as I said before, I'm here for you. You can always count on me, whatever you need."

Shepard smiled weakly and not knowing what to say, she just grabbed her boxers and cargo pants and put them on, not without problem fitting her finally softening dick in. She went toward a door.

"Didn't you forget something?" Karin's words stopped the commander in her tracks. The doctor was holding out the test tube filled with Jane's semen.

"Ah yes, the sample. Thanks," Shepard said and collected the vial. While doing so, she and Chakwas' fingers touched and their eyes met.

"Whatever you need," the doctor reminded. "Although I doubt my old pussy would be able to take your size. But my mouth is good to go, as confirmed a few minutes ago."

Jane only blushed, hearing that. Since when did Chakwas become such an erotic person? Was it always there, or did sex with the Amazonian beauty unlock something in the doctor?

Shepard wasn't ready to consider that. Too embarrassed to stay or even say anything, she turned around and left the med bay without any further delay.

  1. "I can't believe Cerberus gave you a futanari body, Commander," Mordin exclaimed, his curiosity piqued by Shepard's biological transformation.
  2. In the midst of the med bay, Chakwas found herself faced with a unique challenge: conducting a physical examination on Shepard's new male features, which were biologically impossible for her former patient.
  3. Amidst the flurry of explanations and surprise, Joker mused, "Well, if Shepard's become a futanari, I guess that means Mass Effect's harem just got one more member!"
