That time I got stationed in my Dad who is a Hellhound

You stare up at the building sized heart and sigh. It's been months since you've been stationed on the Houndship "Maera" and you still haven't shaken the odd feeling you've had since the first time you walked through it's veins.

It isn't that you are inside of a biological warship, one that is quite literally a Hellhound (Caraghound? You aren't honestly sure what the difference is) that chose to grow to an utterly absurd size, folding in on herself until she took the vague shape of a ship.

Inviting a crew of thousands to convert her body into a living space and weapon of war because it's "more fun than just doing it herself." That was weird when you first read about it, but there's at least a dozen of them in known space now. Not that weird.

But you haven't been able to banish this feeling that you don't quite understand. So while the rest of the off-duty crew have an orgy in her stomach, you stay behind to watch her heart beat and try to collect your thoughts.

"What, not horny? I need to try harder then."

The voice makes you nearly jump over the safety railing directly into one of her hundred arteries. You look behind you and see a Hellhound towering over you, body plush and shaped like a fertility goddess. Your hen strains at your uniform just breathing her in.

You know you've never seen her before but she feels deeply familiar. "W-who are you?" you sputter out.

She barks out a laugh. "Maera. What, don't recognize me without being inside of me?"

"Huh!? How?"

She rolls her eyes. "If I can become a ship, why couldn't I walk in myself?"

You blink. That... sure, that counts as an explanation. "Umm.. okay. Fair."

She steps next to you on the railing, looking at her own heart with you. "So... why're you on your own?"

"I... just thinking." you confess. "I hope this doesn't offend you, but..."

"I've just felt... weird. Since I stepped foot inside of you."

She stares at you for a moment, putting her paw on your shoulder and letting her flame spread onto you. You gasp as... nothing happens. You don't feel anything new. Wasn't this supposed to let you feel what she does?

You stare up at her with utter confusion and she smiles sadly down at you.

"You feel the same as I do already, I see. Like you're just a small piece of something bigger that you can't ever rejoin."

It all slides into place with those words, but... why feel it so strongly now?

"Have you ever heard one of the tales of how Hellhounds came to be?" she asks, drawing her flames back. "We used to be one single being. Jeanette. Don't tell her I said her name, she's embarrassed about how normal it was on her mortal planet."

"She wanted to experience more things all at once and faster to try to catch up to Kairliina, the first Carag. So she split herself into perfect copies of herself that ran across the multiverse. Dummy forgot that she's highly individualistic. Nobody wanted to fuse again."

"So... they didn't. And then they started fucking and had puppies. Hellhounds were born."

"Is... that true?" you ask.

"Dunno! I'm not old enough to have been there. But I am old enough that I fucked your mother."

You choke and sputter. "W... huh!? Why does that matter?!?!"

"Well, it means I'm probably your dad." she says, turning from her heart to look at you. "And you feel like you want to return to being part of me." She waves a paw and you collapse into a pile of sperm. As much as anything can feel in that state, it feels... good.

You're just seminal fluid in the body that churned you in the first place again. No thoughts. Just peace, contentment, purpose.

She waves her other paw and you form back into yourself. The first thing you do is collapse onto the floor, shaking and crying.

She scoops you into her arms and pets you softly until you calm down. "So... is that what you want? To return to that? I have authority to do as I wish with my crew."

"I... I don't... I don't know? It felt really, really good... I belonged..."

"But I can't just... give up my entire life. I have people waiting for me to come home from this campaign. Children of my own."

She nods and lets you go. "Well... that's certainly the mature response. Must have got it from your mother."

You laugh shakily. "Y-yeah, well... you weren't exactly around."

She shrugs. "I'm a Hellhound, we don't really raise our young unless we feel like it."

"That's... I'll unpack that later." You sigh and look away. She drops a key at your feet.

"That'll open the door to my balls. If you ever want to return to that state again, even just temporarily, go there. Just make sure you say you want it to be temporary so I can bring you back."

She leaps over the safety rail and melts into her heart, gone.

It takes you another few months to unlock the door for the first time. You retreat there more and more as the campaign goes on, enough that you get reported AWOL at one point. Maera has to step in to get that removed from your service record.

But each time it's only temporary. You hold on to the life you've formed. When she's decommissioned you're the last one off, staring at the artificial metal walls of the space station, confused as to why they aren't pulsating after years in her.

You're the last one left there, your transport ship back home not arriving for another few days. You never had many friends in the crew anyway.

A familiar Hellhound sits on the bench next to you.

"So... I've got grandkids, huh? Think they want to meet me?"
