Bathing a Giant

Sam isn't an active duty guardian, but he is in the reserves. Some of the things reserve guardians do are performing tasks like recruiting, attending meetings at the guardian base outside of Clearwater, and making trips to the Unex Labs in the industrial park to test some new gear and magical implements. Sam is so big here because he's testing a mana stimulant at the labs. It's a device built for generation three guardians, ones that learn lipomancy as a standard casting style. The stim would instantly make the user fill with mana and therefore fattening them up as well. To offset the growth that would inevitably occur, the stim also makes the user's body feel lighter and stronger. Problem is, the stim he tested was waaaay overtuned, making Sam swell up so much that he can barely move.

So, Sam spends the day at the labs after getting huge and befriends one of the 'hybrid beasts' named Rina who also happened to be ridiculously huge on the same day. The hybrid beasts are literal giant arcerans who were bred to be very tall and very strong, the equivalent of living tanks that would be deployed against large enemy forces on the battlefield. Rina is one of the three of these beasts that live at the labs. Here Rina is doing some spirit mending limit testing, an attempt by the lab's scientists to try and find the theoretical maximum limit for a mortal spirit mender. She was a willing candidate since she is arguably the strongest of the beasts and also enjoys the feeling of a large pregnancy that spirit mending brings with it.

Sam offered the beasts' caretaker Isabella a break for the day since he was getting along well with Rina, deciding to go to the lab's massive bathhouse to give Rina a shower.

Rina belongs to darknido!

Sam huffed as he started to pull open the massive door to the bath chamber. Every step was a labored one since he could barely move, his massive gut, bouncing moobs, and titanic ass cheeks jiggling with every step he took. This was the least of the dog's problems though, seeing as he was also dragging his huge balls across the floor. When he waddled around in this expanded state, his gargantuan blue shaft throbbed from all of the stimulation his nuts were getting. It took all of his willpower to not paint the lab's sterile grey walls white with his seed right now, although it wouldn't be the first time today. "Ngh..." he groaned, having to stop when the door was halfway open, rubbing the sweat from his brow and trying to get his bearings. "Almost got it..." He looked up to his escort, the literal giant girl who was almost twice his size.

The giant let out a hearty laugh, her voice deep and loud. "You are too polite, Mr. Yaeger," she said. "You should have let a lab assistant open that for the both of us!"

Sam rubbed the back of his head with his free hand, blushing as he took in her appearance. Just like him, she was naked and also comically huge. Both of her breasts were nearly as big as he was, and her belly was easily large enough to eclipse his normal size fourfold. Her navel, popped out and just a few inches from his face, easily conveyed that she was massively, unnaturally pregnant. Although it wasn't clear due to the giant's grown-out, extra fluffy neck fur, Sam as well as the lab's scientists knew that she was wearing a goddess seal collar. He had never seen anyone spirit mend this many spirits at once, although he should have expected that one of the so-called hybrid beasts could manage to carry a burden like this.

"I know," Sam eventually said in reply. "It's just... It's polite for a guy to open the door for a lady. Or at least that's what my mom taught me..."

The giant cooed, clasping her hands together over her breasts. "Aww! You're too cute!" She took a step forward when she reacted, pushing her massive belly against his shaft.

"R-Rina!" he shouted, his face flushing as he wobbled backwards, pulling open the huge door in the process. Losing his balance and squishing even more into Rina's tout belly, he toppled to the floor. Luckily due to the plushness of his butt, the fall wasn't painful in the slightest. His balls churned with need and his mind swam with lust as he laid on the floor. His feet shifted to try and get up, only managing to rub against his twitching nuts even more. "Guh..." he managed to let out, sticking out his tongue and panting for breath.

"That mana stimulant really did a number on you," Rina chuckled. She slowly turned to the side and leaned down, reaching out to give him a hand. Rina's strength was incredible. Despite the current size and apparent weight of her gravid tummy, she was moving almost like normal. "Can you walk?"

Sam reached up, managing to shake the lustful haze that his mind was swimming in. "Hah... yeah." He reached up and took Rina's hand, slowly managing to get to his feet even. His heart was thumping in his ears and his cock throbbed for release, but tried to calm himself down for the moment. "I think... I think that the stim device they gave me might have been tuned for someone the size of you or one of the other hybrid beasts..."

"I can't say for certain if that's the case, but..." Rina smirked down at the small dog. "Despite our height difference, you definitely look like you're my size. If you know what I mean."

Sam sighed, covering his eyes in embarrassment. "Rina..."

The giant giggled, reached down and patted Sam's head. "Hey, I'm just messing with you! Let's go have a bath, hm? You said that you would wash the front of my belly since there's no way I can reach."

Sam opened his eyes and nodded. "Y-Yeah... let's do it."
