[Previously: “Tell them I’m willing to give them anything!” I snarl. He actually looks scared and I press against the incubator harder, “I haven’t been trying hard enough as of late, I, I once refused a guard and he crushed-”] 


I hold my head, “It’s my fault all I had to do was-”

I startle as the doctor wraps his arms around me. Especially since he doesn’t look like he enjoys it. I do though and soothed press into him. 

“Please.” I beg him softly.

“I…I’ll make sure they all get hosts.”

I press into him harder in relief and refuse to go back to the bed until he brings me the few that responded to the message.


They stand looking down at me. 

Maybe something about me pitifully curled up against the incubator with my eggs but two of the few step forward saying they’ll do it. 

I look up at the doctor. I have no idea if he has the right equipment. I nod and thank the two that stepped forward together profusely. 

The doctor starts getting them prepared.

I point at one of the three standing back, “I’m sorry your species isn’t compatible with mine.” They look irritated but at the doctor’s request leave.

I observe the other two hosts. One looks like he’s disappointed and the other looks like they want to eat me alive. 
I remind myself I will not refuse again.  The disappointed one looks up at the bigger alien and mutters that they thought I’d be putting the eggs directly into them. I tilt my head, “I can make it accurate if you'd like?”

He raises an eyebrow. “I came here to get pumped full of eggs, directly from your breeding tentacle.”

“Tentacle?” I laugh once and turn to the doctor.

“Breeding apparatus.” He corrects.

“Same thing.” The small alien rolls his eyes and smiles.

I’m still trying to figure out what he means when the two others look nervous. 

“We were hoping it’d be a medical process, not-”

“I will be taking care of that, don't worry.” The doctor proceeds to explain that the eggs could be safely inserted without me needing to be part of the process. 

‘Interesting,’ I think head tilted. I can feel my mouth start drooling at the repeated talk of breeding and inserting. I cover it hoping not to turn off the two nervous ones. 

The doctor asks them if they’d want any of my chemical mixture and they seem grossed out and uncomfortable when I show that it’s from my tongue. I recoil a bit looking down and the doctor softly explains he could sterilize it before giving it to them but would recommend.

I’m starting to feel more and more ashamed, reminding myself that this is how other aliens see us. I have to just endure and not think about myself. The doctor takes a second to grab a bottle and I go with him.

“Please extend your tongue.”

I obey, waiting as long as I can before, curious, I look up. Eyes widening a bit at his fascination with my tongue. I’m flustered a bit as he milks it privately behind a curtain to fill the container.

“Wait here.” He says softly.

I stay because he asks me too. The two nervous ones joke and gag about drinking the liquid but I can hear and smell the difference when it starts working. I want to get up but I dig my claws in, only watching as the doctor carefully retrieves some eggs. 

Tensing I subconsciously lean forwards a bit. He glances my way looking calm and confident. Soon his voice comes from behind the privacy curtain explaining the process and what he’s going to do. His voice is even soothing to me as he starts inserting them into the first host. 

I look over startled as someone slips through the curtain. I was too focused to notice them approaching. He presses a finger to his lips and I freeze up a bit.
'I promised myself.' I clench the bed as he looks down at me. 

“You’ll carry my eggs?” I ask softly as he obviously intends to breed with me. 

“Of course.” He says it way too toothily, and in a way that I don’t like. 

I watch not resisting as he encourages my "breeding appendage" as the doc put it out. I lean my head back twitching from the stimulation as the larger humanoid treats me very similarly to a host. I wince a few times but remind myself that if it’s a bigger male, he can carry quite a few eggs. 'It’s worth it.' 

I startle when he begins kissing me and that encourages my tongue into his mouth but then he grabs it. 

“I’m not going to have you drugging me and taking control of the situation. Oh no.” He chuckles and is starting to hurt me as he isn’t being careful nor does his spit have anything to relax or warm my muscles. He seems to get more excited from my pain and whimpers. I gasp as he presses in all the way suddenly. Something warm and unpleasant smelling fills me, something I’m familiar with at this point, but it also means it’s over usually. I catch my breath wincing.

The small alien suddenly notices he’s standing waiting alone and clears his throat, “Um doc, sorry to interrupt.” 

The curtain swishes back and the doc snarls, “Get out!”

“But.” I start to protest. “He said he’d carry eggs.”

The humanoid smirks, “It’s fine I’m already done,” and leaves even as the doc looks like he wants to hurt him. I sit up and flinch as it makes a bit of a mess. As I'm trying to cover myself the doctor looks at me in horror saying, “He actually.”

I’m starting to get angry, “You promised! You said you’d get me hosts, why did you chase him off?!”

“You don’t want him as a host!”

“Yes I do!” I freak out wings fluttering the stub reminding me painfully of the injury and I glance at the incubator and deflate. The two nervous ones could barely take half, “I needed him.”

“He wasn’t going to let you put a single egg in him, he was only preying on your desperation.”

I blink slowly. “He said he would.”

“I’m a human I know when another humanoid is lying.” The doc soothes, “I promised I will get all your eggs hosts, it’s alright.”

I glance at the eggs, “They’re already weaker.” I feel my mouth move in a more aggressive way, “If any of them die 
doctor I-”

“Ahem.” The smaller male alien flushes, “Are you okay?”

I move my head looking down at him, “Why wouldn’t I be?”

“That guy seemed really shitty.” He tries not to look.

The doctor observes us and leaves to return with things I can clean up with. I note that humans find it embarrassing to watch. Once cleaned the alien makes a little worried noise over me. Hiding it behind his hand like that would somehow hide it from me.

“He would have held quite a few eggs.” I say deadpan and still upset.


The smaller male carefully reading the room smiles wide, “You wanna see how many I can hold?”

My antenna twitch at the first excitement I’d felt from anyone else about being a host before. “Are you sure?” I surprise myself asking.

He nods, “I’ve actually put stuff like that in me before, never real of course but…”

My body moves on its own. Something irresistible about this eager alien. “How accurate do you want it?” I ask a little embarrassed.

He shivers looking briefly nervous, “Wow you’re big, uh just be gentle but I want you to enjoy it too.”

I shiver and then inform him, “I’m going to put my tongue down your throat.”

“Oh gawd yes,” his lips tremble and lets me pull him into myself. Eyelids fluttering closed.

I listen very carefully for noises of pain or discomfort but embarrassingly loud noises of pleasure are leaving the male. Obviously overdramatic because he becomes quieter once the chemical actually does take effect. He moans softly, flushed and touching me in ways that are so different so…gentle I try to return the favor.

I press my ovipositor forwards and jump as he guides it between his legs. The chemical did its job. He arches, taking it in easily until he gasps making a mhm noise and writhing a bit. I relax watching closely as pleasure is oozing from him, and then I give him as accurate of a breeding session as I could, even sending him “blanks”. 

I double over in relief, finally convincing my body that I was empty. The doctor brings the eggs and hands them carefully one at a time to me to put inside the almost delirious alien at this point. 

“More.” The whisper shocks both of us and he smiles, “I’ve done more with toys at home, I can take about a dozen more easily.” My antennae straighten a bit and then I eagerly kiss him adding more relaxing chemicals as the doctor monitors him closely. 

“More.” He gasps panting and looking a little strained once receiving said dozen. 

“I can’t recommend it.”

“Doctor, this is actually my expertise.” I tell him very seriously and turn back to my host. Sniffing them carefully with my antennae I even more carefully massage their stomach. 

He bites his lip and moans. “Just…” he pants, “Two or three more please.”

I tilt my head, “You could uncomfortably handle five more.”

He looks beggingly at the doctor, “I’ll do four then.”

I glance back at the incubator. “That would leave six.”

The host's face falls a bit, “Oh no, what happens to them?” He looks up at me anxiously.

I look away. 

The doctor stares at me for a long time. “They’ll be okay.”

The little alien startles me by lifting a hand to my cheek, “It’ll hurt like hell but I think I can take em.”

“No.” I shock the doctor saying it at the same time as him. 

“He says they’ll be okay.” I look at the doctor firmly for a second and then encourage the last four into the alien. 

He orgasms tensing and gasping in pleasure, gripping my arms in a pleasant way. 


When he comes down he’s quiet but happy, sitting up on the edge of the bed. I’m pleased as he looks at his stomach holding it gently. I rub against him and when he likes it rub against his stomach too.

“Stop.” He blushes, “Don’t make me fall for you.”

“You're my favorite host.” I say honestly looking up at him. 

“You’re my favorite...” He thinks about it but doesn’t finish, instead moving on to the next thought, “I can’t wait until your next clutch.” I fluster and feel my wings shivering excitedly.

‘Things are hopeful here.’ I think to myself.

I lay against the incubator staring into it at the last six. The doctor has not found another host. I am refusing to “even lay in the bed” until he does. The nurse brings me food and water only to see the last meal is still there untouched. I don't acknowledge them or the doctor when he comes to check on me.

“They’re dying.” I croak.

“I-”

“Still looking, I know.” I close my eyes and press hard against the glass separating me from the faint little heartbeats.

“I found one.” He sounds so strange that I look back in more concern than excitement. He makes a very uncomfortable face, “Since I couldn’t find anyone else…”

“But you said?”

“I’ll take the last six.” He looks away and then back carefully, “If that’s okay? I figure I can best research the whole process if I actually experience it, but I need it to be a secret.”

I nod, “Because you are ashamed.”

He goes red and I recognize that he’s angry, “No,” he grits out, “I’m the only doctor on day duty and if I suddenly willingly become indisposed they’ll chew me out, give me a written warning and whatever. I don’t want it on my perfect record.”

‘I don’t know why he said he’d be ashamed in such a long winded way rather than just agreeing with me.’ I twitch an antenna a bit in acknowledgment.

“It’s a bit reckless, especially since humans aren’t the most optimal hosts for your eggs and now you have to-.”

“Humans are perfectly fine hosts, if you don’t get the aggressive ones.” I look at him unblinking.
He looks at me confusedly.

“You kept interrupting me before, the men that did this to me,” I gesture to one of my arm stumps, “worked with the first host I was ever given.” I rub my stomach and shrug. “We were always told humans were like that smaller male alien that came in, eager hosts.”

“Ah.” He says and then frowns like whenever he remembers the fake host that only wanted to breed me apparently. I’ve let it go but the doc can’t seem to. ‘Urging me to make a report so they can punish him.’ I don’t want to in case he wasn’t lying about wanting to carry eggs. I wouldn’t want to lose a potential host later, ‘This line of thought also pissed off the doctor.’

I stand and lean down over the doctor who tilts back looking up.

“You’ll want the relaxant.” I say and he looks up at me expressionlessly until I turn to the counter to drool some into a container. I shove it at him and turn back to look at my eggs. “If you were just gonna do it anyway you shouldn’t have waited so long and let them get so weak.”

“It was a difficult decision!” He sighs watching as I take them out of the incubator. Chugging the 
liquid with a wince he backs towards the curtain area. “I’m sorry?”

I blink looking up. 

He undresses and seems a bit uncomfortable.

“You have less hair than others.” I gesture.

“I groom.” He says and lets out a startled noise as I touch him.

“I need to prepare you.” I look up, he flushes a little as the chemicals take effect, “But not much.”

He grumbles something until he’s soft enough to not damage the eggs then I insert them. He starts to get up and I exclaim, “Wait they’re not in enough.”
He looks confused then horrified. I tilt my head, “I won’t force you doctor.” 

He’s unsure, “What do you mean?”

“Normally when one of my species lays inside another it's through our-” I gesture.

“Oh god.”

“I’m not going to put it in you.” I say insulted, “I can move them deeper in a few different ways.”

“Just do it before the aphrodisiac wears off.” He groans covering his face.

“Take a deep breath,” I soothe.

He glowers at me and I smile a bit unsure why he did this at all but appreciative. I try not to make him uncomfortable as I push them deep enough to be safe from his body trying to reject them, once deep enough they’ll latch on, on their own.

I remove my fingers and then murmur, “Now your body should try pulling them in deeper, let it do so.” Almost immediately he closes his eyes and shudders. I watch him struggle against pleasure for a while. 

“Please… go… don’t wanna,” he says finally and I leave quickly at his request. Only hearing when he orgasms. At least that means it worked. 

When I return to check on him, he doesn’t tell me to stop so I sit on the floor leaning against the bed, listening to him regain control of his mind and senses. He reaches down and I lift my hand to him which he holds silently.

Worried he’ll regret it. I look up and dip my head. “Thank you.”

“Why are you groveling again?” He sounds breathless going to touch his stomach but catching himself. He looks at me for a long time. “I thought it’d be more painful.”

“If you took as many as the other guy you would have felt very full.” I smile and stay submissive watching his every move. He has my precious eggs inside him and I would not let myself piss him off. “Thank you.” I say again. 

He nods and starts to get up. I assist and to my surprise he doesn’t push me away. He goes to his desk slowly and then starts writing some notes.

I stand up straighter. The revelation that all of my eggs are in hosts is amazing.
