Chapter 4 - White Blood Cell, Killer T Cell, Common Cells

Her kind can be easy targets for viruses, because of their complete lack of defense, but because they serve one very particular function in the body, and are not good for much else, they’re usually disposed of very quickly. She has to be careful, and even with her caution, there is no way to protect herself, should a virus decide to target her.

That is why she is incredibly grateful to the Neutrophil that rescues her one day, just in time to make sure that she is not seriously injured. She is so grateful that she wants to show him that, and there is only one thing she can confidently do.

“If you have anything you want me to do for you before you go,” she says, “then I’ll do it. I know that it’s my job either way, but…”

“No, I understand,” he replies, and hesitates for a moment. “But, really, I was just doing my job, so you don’t have to.”

“I’d really like to be able to do my job,” she admits, trying her best not to be pushy about it. This Neutrophil was incredibly brutal while taking down the virus that had her in its clutches, but now he is polite with her, almost needlessly so. It’s hard to imagine someone telling her that she should not have to use her body to thank him, when they’re supposed to want to use her body regardless of what they may have done for her before.

In fact, because she needs to fuck to survive, using her is the best thing someone can do for her. Unless he just isn’t interested at all, then he is being way too polite, in a situation that doesn’t call for it at all. If he turns her down again, she will not push, and will surely happen upon someone else soon enough.

“When you put it that way…” he says, trailing off. “Come on, let’s go over here, then.” He gestures to a nearby bench, and she nods, excited. He’s a very attractive cell, she thinks, even beyond her basic attraction to anyone who wants her.
Neutrophil has her sit down, but surprises her by kneeling down in front of her, spreading her legs as he does. With his face between her thighs, he looks up at her and asks, “Is this alright?”

“You don’t have to ask, but...are you sure you want to do that ? You don’t get anything out of it,” she replies.

“That’s not necessarily true,” is all he says, and, with as much confirmation from her as he’s going to get, he leans forward and teases her with his tongue, running it along her slit and causing her to whimper for him. This is a type of pleasure that she has not yet experienced- though it will feel good for her, it is just as useless as masturbation would be, and yet she can’t help her excitement as Neutrophil pushes his tongue inside of her, intent on pleasing her.

And he does exactly what he sets out to do, surprisingly gentle and caring, once again a sharp contrast to the brutality he’d shown in battle. She is left entirely helpless as he works his tongue inside of her, overwhelmed and infatuated, and even more desperate to fuck him, and show him just how good that she feels.

It feels so strange to be brought to orgasm without making him come first, but it leaves her more in the mood than ever before. As she tries to catch her breath, he stands up, and she gestures for him to sit beside her. There is a part of her that worries that he won’t get it, and might think that that’s all there is to it, but fortunately, he is not that dense, and once he sits down, he undoes his pants so that she can climb onto his lap and ride him.

Even now, he remains gentle, a much calmer lover than she would have expected, and she catches her mind wandering to Killer T for a moment, a lover who is about as rough as he looks. Neutrophil seemed rough only to turn out the opposite, but she likes that, and she loves him, telling him as much as he lazily pushes up into her. Bouncing on his lap, she pushes the other man out of her mind entirely, her focus remaining entirely on Neutrophil.

Another busy day for everyone means another day with no work for her, leaving her once again stumbling around, weakened and desperate, hoping to find someone to fuck her. It must have been a particularly rough day for there to be this little action to be had, and as her needs begin to overwhelm her, she wonders what to do.

Exhaustion begins to set in, a clear sign of her starvation, and she worries she won’t be able to take another step without collapsing. Leaning back against a building, she puts a hand between her legs, absentmindedly fingering herself to try and ease the ache, though all it does is fluster her more. She feels hot all over, and dizzy, like she could collapse at any moment. In fact, she is so out of it at this point that she doesn’t notice him until he puts a hand on her shoulder and says, “You just putting on a show, or what?”

Gasping, she looks up at Killer, blinking as if he might vanish like a mirage. But he’s real and she shakes her head, mumbling, “No, I just....so tired, I haven’t...nobody…”

“Oh, you’re that bad off?” he asks. “Fine, fine, if you insist, I know what you need...wouldn’t want you dying on me over something that stupid, is all. Don’t think it means anything, slut cell.”

FUC doesn’t care what his motivations or excuses are, as long as he does it. Of course, she knows that she would be grateful to anyone, but there is something special to her about it being the same Killer T Cell that she hasn’t been able to get off her mind. She knows that she isn’t supposed to have a favorite, or spend nearly this much time thinking about him, but she can’t help herself. Something about all the time they have spent together stands out against anyone else.

He has her bent over soon enough, his hands on her wrists, gripping her so tight that it almost hurts, but she barely notices anything beyond her need for him. Killer is rough as he shoves his cock into her, perhaps even more rough than usual, and as her senses begin to return to her, it occurs to her that he might be feeling a little pent up as well. It has been a while since the last time she saw him, though it may be wishful thinking on her part, wanting him to miss her when she’s not around. That definitely isn’t a part of her job.

He pulls on her wrists as he fucks her, pushing her forward with each thrust and yanking her back hard, so hard that it hurts and she loves every second of it, so glad that he was the one to find her like this, and so glad that she gets to let him use her over and over again. As long as she never tells anyone that she has a favorite, then maybe it’s not so bad for her to secretly favor him.

~X~

Killer wastes a lot of time with the slut cell after that, frustrated with himself for needing her this much. He seeks her out far too often, and always her in particular, and when he can’t see her, he gets even more frustrated. The fact that he found her near starvation when he himself felt like he was going to lose his mind if he didn’t fuck her soon felt almost like fate, in the moment.

But after hours spent fucking her senseless, he is reminded that for her, it was a matter of life or death, and for him, it was just ordinary loneliness. He should have been better than this, but instead, he finds himself dependent on her, perhaps even addicted.

~X~

A lot of her ordinary days involve her riding Helper’s lap to help him destress while he’s working, ending up on a live broadcast more often than not. Some days, she stops in to visit Dendritic and take his worries away, and some days she lets B Cell boast about his achievements and, if he isn’t using her mouth, she will praise him as well. Some days, she eagerly listens to Basophil without understanding a word, finding his voice soothing and his cock fantastic. Countless Red Blood Cells will stop her after they’ve finished deliveries, and she meets quite a few Neutrophils, while holding a particular fondness for the oddly polite one.

And more often than any of those, she will find herself with a crowd of Common Cells, three holes and both hands seeing plenty of use, and plenty more cells lined up to have a turn. She is so used to looking out into the crowd and seeing several similar faces, but when she notices someone towering above the others, his height more than enough to make him stand out, without factoring in his broad shoulders and his uniform, she is absolutely elated.

She never thought that she would see the day when her favorite Killer T Cell would line up to wait for his turn with her.

~X~

Despite never being mentioned in the science books, Free Use Cells have a very important job. Every day is full of work, but fortunately, they love doing their job just as much as any other cell, and maybe even as much as any cell enjoys having them.
