Fortunately for the plans of certain alien women, the Normandy has a day-night cycle despite being in the vacuum of space. This was a common enough thing, as ignoring the day-night cycle completely was a known cause of space madness and each and every space-faring species quickly learned to avoid that sort of thing.
 
As such, the Normandy’s medical bay is dark and empty when a certain Quarian all suited up sneaks her way into it. Heading over to a certain room of the medical bay, the Quarian in question crouches down to eye level with the door panel, popping it open and working at it for a few seconds before the door itself hisses up into the ceiling.
 
“Bwah…?”
 
“Shhhh…”

Tali Zorah has her hands lifted up to show she’s not armed as she creeps into the room, the door hissing shut mere moments later behind her. Climbing out of bed is the red skinned creature that they’d brought back with them from Omega and he blinks at her even as he tilts his head to the side curiously.
 
“I’m not here to hurt you. I just… need you to help me out. Your seed is special… beyond special, even. So please just relax. Let me… let me do what I came here to do.”
 
In the end, Tali slowly sinks down to her hands and knees and crawls forward with her ass raised high in the air. This seems to relax the creature, as well as arouse him just as she hoped. By the time she finally reaches him, his cock is already poking out from under his loincloth. Thick and massive and musky… it’ll never fit in the feed port of her suit’s helmet.
 
With a shaky, timid sigh, Tali squeezes her eyes shut… and then reaches up to carefully begin removing her hood and helmet. It’s incredibly risky to do so, though not AS risky as it could have been. They were technically in a clean room right now, as every sealed room in the medical bay also doubled as a sterilized environment.
 
However, that was ignoring the creature in front of her very much NOT being sterile. Still, all signs pointed to him being able to cure her species’ immune deficiencies. If that was true, she needed to find out herself. She needed to confirm it immediately.
 
Taking in another shaky breath now that she’s exposed her face, Tali reaches out and wraps her fingers around the creature’s cock. He doesn’t try to stop her, simply watching as she starts to stroke him up and down with her hand.
 
“Gweh…”
 
Biting her lower lip, Tali glances between his dick and his face, her nostrils flaring as she breathes in his scent.
 
“N-not enough, is it? This much… it just isn’t enough. You need more. You need… my mouth.”
 
It was why she’d removed her helmet in the first place to be fair. Letting out another sigh, Tali leans forward and opens wide. She hasn’t ever fellated anyone before. Not a Quarian and certainly not an alien species. But here she is all the same, opening her jaw as wide as possible and trying to wrap her lips around the red alien’s huge fat dick.
 
She chokes rather quickly of course. He’s way too big and she’s way too inexperienced. But from the sounds he makes, she’s sure that he’s enjoying himself so she keeps going and going. Tali loses herself in the experience, having no idea how much time passes as she bobs up and down on as much of his cock as she can fit past her aching jaw.
 
Until finally… he cums. With a gurgle, Tali gags on his seed at first before realizing what’s happening. This was exactly what she came here for! Right away, she begins to swallow, drinking down the red alien’s cum without hesitation and hoping that its healing properties would do the best.
 
Gulping away, Tali’s eyes very nearly roll back in her head from the taste. She didn’t expect his jizz to taste so good on top of everything, and she guzzles it down like there’s no tomorrow, swallowing every last drop that doesn’t spill down her chin and onto her suit-clad breasts.
 
Finally, Tali pulls back, panting a little bit as she wipes her mouth with the back of her hand.
 
“Gweh?”
 
Ignoring the alien for a moment, she quickly brings up her Omnitool, getting some scans of herself. Much to her satisfaction and shock, its working almost immediately. Her nonexistent immune system is being built in real time right before her eyes. The Omnitool scans can’t keep up.
 
It’s around that time that the door to the room slides open again. Tali whips her head around but relaxes when she sees that its just Samara. The ancient Asari Justicar steps into the room and lets the door close behind her, stalking forward as she stares at the red alien’s twitching cock.
 
“I see you decided to start without me.”
 
Blushing a little bit, Tali just crosses her arms over her chest.
 
“Like you wouldn’t have done the same in my place.”
 
The Justicar just smirks at that, even as she grabs the creature and lifts him off of the floor and onto the nearby raised bed.
 
“I wouldn’t have. Not only because I lack the skills to break into a secured room like this, but also because… it’s not me that I need this creature’s seed for. I’m only here because there are Ardat Yakshi who have never once killed and deserve a chance at normal lives. You on the other hand… you aren’t here for entirely altruistic purposes are you?”
 
Tali blushes profusely at that. She wishes she could deny it, but in the end… Samara is right isn’t she? The trickle of cum still leaking out of the side of her mouth is proof of that much.
 
“F-Fine… maybe you’re right. Whatever. Did you bring them?”
 
Samara hums and nods before revealing the set of cannisters she’d procured for the evenings activities. The Asari Justicar was only half-right in the end. While Tali did have selfish reasons for coming here tonight, she also had selfless ones as well. Namely, she knew that if they could reverse engineer whatever was so special about this creature’s semen, then they could make a drug for the entirety of the Flotilla Fleet that would solve the Quarians’ immune system issues for all eternity.
 
Of course, Samara wants his seed for not entirely altruistic reasons as well. She has several more Ardat Yakshi daughters, after all.
 
“Let’s get to work.”
 
Samara kneels down in front of the red skinned alien, his feet dangling off of the side of the raised bed on either side of her head. Holding up a cannister, the Asari Justicar proves that she has no issue with getting her hands dirty both figuratively and literally. One hand jacks off the creature’s cock with mechanical precision while at the same time Samara leans down to suck and slurp and polish his massive meaty balls as they dangle off the side of the bed.
 
Tali watches this with a blush, shivering in excitement and finding her hands moving over her body as she begins to strip out of her suit altogether. It’s not like she needs it anymore after all, not at this point.
 
Eventually, Samara’s handjob-balljob combo pays off and the red alien groans as he ejaculates again, this time into the cannister. However… neither woman fails to notice that he doesn’t cum nearly as much this time. Not even enough to fill more than half of the cannister in fact.
 
“… I don’t think a hand is going to cut it, Justicar. I think the creature needs more stimulation than that to produce larger loads.”
 
Looking at her half-filled cannister in disappointment, and then noticing Tali’s state of nakedness, Samara slowly nods.
 
“Hmph. You might be right.”

Straightening up, the Asari Justicar pulls down the zipper of her armor and begins stripping naked as well. Meanwhile, Tali moves in on the red alien before deciding to go for broke. Turning, she presents him with her big wobbly purple ass, biting her lower lip as she shakes her jiggling booty in his direction.
 
“D-Do you like what you see? It’s all yours if you want it… if you want me~”
 
Panting needily, Tali feels up her tits as she shakes her ass. However, a moment later and Samara is there as well, scoffing as she also turns and presents her far more toned blue butt in his direction. She, unlike Tali, has a much more toned body in general and begins to twerk in a way that Tali isn’t really capable of.
 
“Is this what you want, creature? To see strong, independent women debase themselves for you? Well then, have a good long look. Enjoy the view. Because I promise… I am willing to do anything and everything it takes to fill every single one of these cannisters to the brim with your seed.”
 
Tali blushes at Samara’s confidence… before slowly nodding.
 
“S-So am I!”
 
Both look back over their shoulders at the creature expectantly, even as it stares at them unblinkingly.
 
“Bwah!”
 
Hopping off the bed, he leaps forward onto both of them, his big hands clapping their ass cheeks together as the two alien women gasp in surprised delight.
 
And then… the fun begins.
 
-x-X-x-
 
PLAP! PLAP! PLAAAAAAAAP!
 
“OOOOHHH!!!”
 
As Boko fills Samara with his seed, the Asari Justicar squeals like a stuck pig and cums her brains out all over his cock. Her blue body shakes and spasms, shuddering under him.
 
An hour later and things aren’t going great for our intrepid heroines. Or they’re doing fantastic, depending on who you ask. But they definitely haven’t gone according to Tali and Samara’s plans. The cannisters lie off to the side, only one half-full of semen just like back at the start even after all this time.
 
That isn’t to say that Boko hasn’t cum since though. The Red Bokoblin has cum buckets, in fact… its just that none of his seed wound up where Tali and Samara initially wanted it to go. Of course, it’s entirely possible they don’t care too much about how they initially wanted things to go anymore. It’s entirely possible they have… different priorities now.
 
As Boko cums inside of Samara yet again, the Asari Justicar is making quite the stupid expression. Her eyes are crossed, her lips are forming a puckered ‘o’, and she’s shuddering in ecstasy as she cums and cums all over the Bokoblin’s cock.
 
It’s not the first time either in the past hour. His big fat cock has wrecked her… and Tali as well. The cured Quarian is laid out to the side, covered and filled with cum leaking from multiple orifices at this point.
 
As Samara droops downwards and falls off of Boko’s cock, winding up face down on the ground and ass up in the air, Tali lets out a groan and slowly lifts her head up, pushing herself onto her elbows as she stares in dismay at the defeated Justicar on the floor at Boko’s feet.
 
“He… he’s just too much. W-What are we supposed to do? He’s completely overwhelmed us…”
 
Samara just moans in response, not even capable of words at this point. The Asari Justicar is trembling and spasming with the aftershocks of her latest experience on Boko’s cock and its making her look like a particularly sexy flopping fish as a result.
 
Boko the Bokoblin, meanwhile, simply tilts his head to the side, watching them both as his cock twitches. He’s ready to go another round… but are they?
 
In the end, they don’t get a chance to find out because right after Tali says that he’s too much, the door to the room slides open again, admitting yet another woman silhouetted in the frame.
 
“… Too much for you, maybe. But he’s certainly not too much for me.”
