The day that changed the existence of a certain slime started like any other, to it at least. It had moved along the bushes of a forest full of weak monsters driven by its basic need to absorb moisture but then it detected something new. The slime might not have proper colour sight but it did see humanoid creatures pressed against each other and connected. Something in this made the slime only stare at it between the leaves.
A large man mostly wearing leather armour was embracing a smaller female elf sideways. His cock was striking hard into her pussy but the elf was taking it in full. Though she was not looking happy about it and was clenching her teeth. Her black hair was a mess and there were tears in her silver eyes.
Both of their skins glimmered with sweat and the elf's long ears twitched at every thrust. Her black mage robe was rolled up to her neck and the male's arms wrapped around both sides of her hand-sized breasts. Most of the bags surrounding them were from the elf's utility belts laying on the ground.
"You failed me the last time. I don't want to keep you just because you let me have your holes," the man mutters into the elf's ear.
"Then let me go, damn human."
"Naah, I will cum deep to leave something for you to remember me by. I heard you give it to anyone who asks it anyway. Your big hips were made for birthing after all. Maybe your breasts finally grow after having some bastards."
The elf bites her lip as thick cum is thrust into her womb. The man tightens his grip as he keeps pumping into the stretched hole but the elf is not even trying to resist and her eyes glaze over. Her nethers swell and radiate red on the almost pale skin.
When the man is done he rolls the elf off to the ground and she stays there. Her pussy twitches like it still was getting pounded and her legs tremble.
"Goodbye, Vira."
The man stands up and grabs his bag. Vira watches him leave trying not to show any emotion even after he is no longer visible. Her flexible elven pussy is barely gaping even after that violent ramming.
"Human scum, it was you who evaded to right without notice," Vira mutters. She stands up with shaking legs and collects her small bags one by one.
"Lowly elf should be honoured to have the honour of being with a noble human," Vira keeps talking to herself in an exaggeratedly annoyed tone.
"I will let even an elf take contracts with me if you keep no underwear."
"There is no way another licenced hunter will take some filthy elf even other elfs kicked out."
"I sold your fine elven underwear, not like someone like you needs them."
After picking up her stuff and putting them on the belts Vira lifts up her robes and looks at her shapely hips and the pussy under them. Seeing how it had already completely recovered and gained normal colours almost disgusted Vira on top of the fact she could still feel the hot seed inside.
"Damn, almost nothing is coming out."
With annoyed steps, Vira walks to a river nearby and the slime follows her unseen. After attaching her hitched robe corner up to a belt hook keeping it above her hips she dips her fingers into the water before pushing them into her pussy. The slime watches as the elf's big exposed butt moves up and down. The hand is sinking deep into the flesh-hole stretching it and the slime moves closer lured by the moisture dripping down.
"Who is that?"
Vira turns around and sees the slime slowly creeping closer to her. Fire bursts in her hand but it fades in seconds.
"Just something I need."
Vira has a devious smile but is soon fades back into nothingness. With fast hands, the mage grabs a bottle from her shoulder bag and empties it on the blue slime. It gains a reddish hue as the creature absorbs the moisture of the potion.
Dropping to her behind Vira spreads her legs to the slime. Her fingers spread her tight pussy that is now wetter than with the human.
"Come on slime, use your instincts and attack my pussy. Feel free to break through and suck the filth from my womb. The healing potion should be enough."
The slime changes shape and looks like a large reddish transparent dick. A smile flashes momentarily on Vira's face again.
"Ooh, aren't I lucky. Just the right slime for this job."
Bending its body the slime squirms into the presented hole. It gyrates as it's primary way of moving and shakes Vera's insides digging deeper.
"So solid," Vira exclaims with dilated eyes. Her hips gently rock the slime and a smile that is more permanent creeps onto the elf's lips. Vira's insides are gently rubbed slowly stretching them further, something she had not experienced after her exile from the elven kingdoms. Humans only wanted to see how much her fabled elven pussy could take and only cared about themselves. Then again she had wanted something out of them every time.
"Come on, pressure your way deeper, aah, not that I mind but I need you into my womb right now."
With two hands Vira grabs the slime-rod outside and pushes it deeper. Her insides bend into her large limits and more pressure focuses on her womb's entrance. The elf's juices mix into the slime and her clit is swelling from rubbing into the solid but soft creature.
"Come on break me."
The desperate elf thrusts up with her hips while pressing down but her hands are just not strong enough to push the slippery slime entirely into her pussy. Vira heaves herself up and lands to a nearby stone to a sitting position.
"Aarhg."
Vira rolls off the stone panting as her womb is pierced into. The slime slides deeper while still gyrating. The elf stares at the cloudy sky with a twisted smile, the healing potion is making her tingle on top of the slimes movements. Vira's belly bulges and her legs tremble but her juice glistening pussy tightly clamps shut trying to keep the occupant inside.
"Hehe," Vira keeps giggling to herself without end and her body visibly vibrates centred on her shaking belly. She loses all sense of time but after her body gets more used to the odd filling sensation her mind gains some of her focus back.
"Okay, you can come out now. I did not plan this through."
Trying to stand up Vira collapses as the slime's gyration increases.
"Hahahaha... I don't want to die like this. Even if it's not that bad."
With both of her hands on her swollen belly, Vira tries to think any solutions. Her mind is deeply numbed but one solution from her past drifts to it.
"Contract spell... Let me think... It needs skin contact... willingness. Can slime even consent on that level?"
Seeing no other option Vira closes her eyes and imagines what the slime looked like. She can't help herself from imagining it surrounded by her flesh. How the slime is making her feel something she had thought not be possible anymore.
"I Vira Naralmoon of clan Niftdragon declare my intent on forming a contract with the... creature in contact with my skin."
Vira's belly shines blue and she can feel the pure willingness for anything in the slime's mind. The contract's mental connection forms between them.
