Author's Note:
This story has a bit of an implausible premise, and was started as a bit of a goof just to get the words flowing. I think it blossomed into something more than its premise would have suggested, but we'll see. Stay tuned after the main story for a fun bonus scene that's not really true canon, but does get some more kinks checked off. I mean, it'll be literally right after the story ends, and you're all just gonna keep reading even if I don't say anything. But still, though.

I felt a little uncomfortable right off the bat when Mom told me she and Lily needed to talk to me. It got even worse when they sat me down, each with a nervous and guilty look on their faces. Still, despite my racing mind, I couldn't possibly have guessed where the conversation would go.
"Honey," Mom said slowly, "as you know, Lily and I have been figuring things out with a few different doctors recently..."
I nodded tightly. Lily, my little sister, had been having some health problems that had developed in her mid-teens. If anything, they'd been getting worse as she got older, and turning eighteen hadn't helped anything.
"It's not, like, bad news, is it?" I asked.
Mom shook her head. Lily refused to look at me. "It's good news, actually," Mom assured me.
"Neither of you look like it's good news."
"Well... it's good, but strange."
"Messed up," Lily mumbled.
"What kind of messed up?" I demanded. "Just tell me, would you?"
Mom sighed. "Jess, honey, it's not that easy. You're not going to like this either. It's taken Lily and I a while to come to terms with it."
I swiped my fingers back through my hair and took a deep breath. "Well, listen, either you tell me and we deal with it, or I'm outta here. I can't just sit here all day while you make me nervous and don't tell me anything."
Lily shifted uncomfortably. "Mom, maybe we shouldn't yet."
Mom set her jaw firmly. "No, Lily, we have to. We talked about this."
"I know, but... it's so weird."
I rolled my eyes. "Anyone gonna let me in on the secret or what?"
Mom raised her hands and dropped them. "Fine. Lily has certain rare deficiencies. Proteins and nutrients and stuff."
"Fine," I said. "What's the big deal? Get her some supplements."
"That's what we're working on. It's just that we need something very specific."
"Ok. So?"
"Something from you," Mom continued, tone indicating that she hoped she'd hinted closely enough.
She very much hadn't.
"What could I possibly have?" I demanded. "I'm not a scientist or doctor or anything."
"No, honey, but you're a boy," Mom said, twisting her fingers anxiously as she spoke. "And you're Lily's closest male relative."
"You're not wrong. But so what?" I paused. "Oh, shit. Does she need a blood transfusion or something? Why didn't you just say that?"
"No, not blood," Mom said.
"So what, then? Something else?"
"Yes."
I sighed and tried to stay cool. I was not having fun with this game of twenty questions. "Please just tell me what she needs."
"Well... it's like..."
Lily had herself all scrunched up into the smallest ball she could make. I'd assumed she was out of the conversation, but apparently Mom's lack of answers was bugging her almost as much as me.
"Cum," Lily blurted. "I need your fucking cum, alright?"
"What?"
Mom winced. "I wouldn't have put it that way-"
"No, you wouldn't put it any kind of way," Lily muttered, having gone bright red. "You made me do it."
I held up my hands placatingly. I couldn't deal with a verbal jousting match between them right now. "Say that again?"
"You heard right," Mom said wearily. "Apparently the very best thing for your sister is your... stuff. Semen."
"Cum," Lily repeated. "It doesn't get any better if you're all evasive about it."
I nodded slowly. "And this was a real doctor you spoke to?"
"I knew you weren't gonna like it," Lily said. "I sure as hell don't."
"Yes, honey, a real doctor," Mom assured me. "If you like, we can all go in and see her together. I know this is going to be hard to process and everything, but it really does seem like it might help. You know we've been trying everything to get some answers."
"Yeah, but... this?"
"This," Mom confirmed. "We kinda thought maybe we'd try it for a week or something, see how it-"
"Wait wait, hang on. Just to be clear, when you say 'try it,' you mean..."
"Gotta eat it," Lily mumbled in a barely audible voice.
"Oh god."
Mom shook her head rapidly. "No, listen. You just do it into a little jar or something. It doesn't have to be super uncomfortable for either of you."
Lily and I exchanged a glance. "Somehow you're not grasping the sheer levels of discomfort here," I said.
"No, I know." Mom sighed. "I'm just trying to make it sound less painfully awkward."
"Not doing a great job so far, gotta say."
Lily had curled up into herself so much by that point that I could barely see her face. She looked about like I felt. It was going to be a long-ass day at this rate.

Further conversation and arguing didn't get us much of anywhere. We took a break to cool down and think things out on our own. I tried that at first, then decided I'd rather not think about it at all. Instead, I loaded up a heavy playlist and lay on my back in bed, losing myself in the music instead of my thoughts.
I'd managed to zone out a bit before Lily came looking for me. I was a bit surprised that she wasn't off hiding in her room like I was, but I also wasn't about to turn her away. I knew she wasn't having any better a time of it than me, and if she wanted to talk I should probably listen.
"I'm sorry about this," she said, perching on the foot of my bed while I sat up and got comfortable.
"It's not your fault. It is what it is, I guess."
Lily brushed her hair back nervously. "It's kinda my fault. Sorta."
"How? 'Cause of your health? That's not on you."
"No. More, like, it doesn't have to be you. I mean, it's better if it is, but in theory any guy's cum would help. There's this whole explanation that this new doctor has, and I don't really understand it."
"So, wait, I'm not sure I follow."
Lily shrugged. "It's better if it's you," she repeated. "And... I wanted it to be."
"What?"
"Not like that. Don't be weird. Just... I know it's horrible and all. But, like, it'd be even worse if it was someone else. Like, what, I'm gonna start blowing random dudes?"
"I don't think that's the only alternative."
"No, it isn't. I'm just saying." Lily shrugged miserably. "I could get some anonymously. I thought about it. But I'd still feel horrible and gross about it. As fucked as it is, it'd be easier if it's you. And it is legitimately better for me, too."
"Lily..."
"Please?" She looked at me with big, pleading eyes. "Just think about it at least? For me?"
"Dammit..."
"I'm so tired, Jess. So tired of having to go to the hospital, having tests, staying home sick half the time, not being able to concentrate for no reason. Just... tired of being tired."
"Yeah, I get that. I want to help. I just wish it was something less... this."
"I know. It's weird. But hey, it's an excuse to lock yourself in your room and jerk off, right?"
"Pff, like I need an excuse."
We exchanged a cautious smile, but awkwardness still lurked behind the facades we momentarily presented.
"You know," Lily said quietly, "at first Mom really wanted me to ask some other boy. Wanted me to think of someone I wouldn't mind fooling around with a bit. I think she thought it'd be easier on me. But, like, you were the only one I could think of who I wasn't just super terrified of asking."
"Aw, come on. I'm the weirdest possible choice."
"Weirdest, maybe, but the least scary too. I knew you at least wouldn't laugh, and you'd want to help." Lily shrugged. "You know I've always been the weird sick kid at school, right? Plus I got no tits or ass or anything. Fuckin' can't grow into this stupid body."
"Tits and ass aren't everything."
"No, but they're something, and I don't have 'em." Lily sighed. "At least with you, it doesn't have anything to do with being attracted to me, 'cause that was never gonna be the important thing."
"I guess not."
We sat in awkward silence a moment.
"Would it make it any better if I, like, helped?" Lily asked.
"Helped?"
"You know. Like, you'd probably wanna close your eyes or whatever, but maybe it'd still feel better if I, like..." She trailed off made a jerking off motion with her hand.
My eyes widened. "Lily!"
"Sorry, sorry. Stupid idea. I knew it was. Fuck. Sorry." She stood up. "I should go now."
"You don't have to, but-"
"No no, that just made it worse. I knew it would. I dunno. I just thought maybe like... 'cause you could pretend it wasn't me and all..."
"You'd still have to do it to me," I pointed out.
"Yeah, but I think I'd be ok with it."
"You would?"
"Don't look at me like that. I mean, just with my hand. Nothing too messed up." She shrugged. "I've never actually felt one, you know. So I don't have all those associations already ingrained. Maybe it wouldn't feel that gross to me. Or maybe it would. Stupid idea either way."
I sighed. "Lily, we probably need to talk some more about this. But, like, you know I love you, right?"
She smiled faintly. "Yeah, I know."
Lily exited, and I was left confused and disturbed in slightly different ways from the end of the previous conversation.
Still, oddly enough, I felt determined now to help her out. Knowing that it was her decision to ask me, agonized as it was, made it better than having the choice forced upon us by some doctor, or even Mom. It was something that ultimately was between Lily and me, and should be up to us. If it was what Lily wanted, what she needed, than I was going to help her, dammit. Weirdness be damned.
I got a small jar from Mom, which was just about as awkward as anything else had been that day, then barricaded myself in my room. I felt super embarrassed and had a hard time getting started, since I felt like both Mom and Lily knew what I was doing, and I kept imagining them creeping outside my door, or waiting to tease me later. I knew they wouldn't be doing either thing, but that didn't help much.
After an overly long porn and jerk off session, I managed to shoot most of my load in the clinical little container. It wasn't as much as I thought it would be, but maybe it was enough. I assumed it had to be.
Not knowing what else to do, I set the jar in front of Lily's door, knocked, the ran away. It was way, way too much to deal with the aftermath just yet. Hopefully if I waited a while, we wouldn't have to talk about it any further.
****
I ended up seeing Lily again before bed, though purely by accident. She was waiting to use the bathroom as I was coming out. I couldn't very well avoid her at that point.
"Thanks for earlier," she said with a tentative smile.
