You get swallowed up by Pinkie's urethra a...
(co-written by Daeklordzx5)

You were almost trapped as the massive member collides with you (gently that's it) and the bulbous gateway behind you, the big cumslit being closing toward, brushing you almost as if it wanted to kiss you but you had other ideas. Unfortunately, like if it has a mind on its own, it too. Suddenly it pushed all the way with you being completely pinned between it and the cushioning cervix. Fortunately, you weren't squished as you somehow had your feet and legs trapped and inserted into the cumslit, feeling the tight tunnel in it clamping on your lower half. You heard the two women moan loudly, vibrating the entire place, particularly the owner of this monstrous cock.

Did she even notice you?
The answer to come was swift and merciless as the penis ground into the squishy, yet firm surface of the cervix, forcing you completely inside.
The squeezing, tightening cum -slickened tunnel gave you no purchase as you slid backward, traveling along the urethra at a downward angle.
There was no room to move, no space to even scream. The only thing you could hear was the wet squelch of moving flesh and your own frantic breathing.
You were struggling on the tight tunnel, it was far more active as it reacted against your movement, it didn't take long before the penis began to move again, you fight against the strong muscles but it all seems to try pushing you more to swallow you further into her like a hungry beast.

Outside

Pinkie sharply gasped as she felt something small struggling within her phallic mass, swallowed the moment she hilt all the way into her boss' snatch.
Her cock twitched as a fresh wave of pleasure raced up her spine, this time from a different source than she was used to
Punk is could not believe what she was feeling. The wiggling sensation raced along her urethra, sending little shockwaves throughout with every movement. In short, somehow she was being both stimulated both inside and out.
Pinkie's outburst did not go unnoticed by her lover, who smiled and willed herself to send rippling waves down her canal to massage and stimulate Pinkie further.
She twisted around and bent over the counter allowing Pinkie to hilt as far as she possibly could and let Pinkie fuck her pony style.
Pinkie started to more with more renewed fervor, unaware that her cock was having a little treat with you, the undulations and muscles pulled you further strongly inside bathing you with more sticky fluid which made your trek even more slippery and easier for your devoured body, going further inside into the party pony, more fluid came to you but it was of the familiar white kind and you were getting deeper and deeper, You held your breath as you fully sunk.
Beneath the turbulent surface of the pearl white cream, you could hear the string sound of a heartbeat or a pulse echoing through the pink fleshy chamber. The viscous substance slowed your descent, holding you in in a soft bubble.
You lingered there for just a moment before you tore your way to the surface gasping for air.
There wasn't a single inch of you not covered in Pinkie's spunk, it covered your eyes, mouth ears, and your hair. The strangest thing was despite all of this you could still breathe, somehow.
You looked around to notice that you had fully descended into a spherical pulsing fleshy chamber as it was getting filled with more of the pony's spunk as minutes passes, you could clearly hear her heartbeats as well her grunts and moans vibrating the entire chamber.

Were you inside of her balls? Seems to be, since the place was getting fuller and fuller by the minute and the sphincter that deposited you inside twitched a lot.

"Ugh! Mrs. Cake!" Suddenly, the entire place started swaying and trembling far more as Pinkie began to pick up the pace, her nutsack swayed and impacted against the Blue mare's clit repeatedly.

The fluids stored inside her testicles churned and sloshed as she moved, throwing the human trapped inside, namely you, in complete disarray.
Some of the semen managed to find its way into your mouth and you were forced to swallow it down.
Surprisingly it tasted more sweet than salty or bitter and it went down fairly smoothly.
If it weren't for the fact that you were literally guzzling someone else cum it night be easy to get addicted to the stuff.
You often not think that you likely drank semen from a herm giantess, as suddenly the entire swaying and trembling orbs you were residing were getting flooded and fuller. Pinkie was nearly her climax if this any indication. Pinkie was going faster, her face contorted into one of pleasure, her tongue lolling out of her mouth as she continues mating with Cup Cake, almost remorselessly and with the intention of breeding her. Feeling all these new sensations was making her get to her limit, she could feel that her momentary lover was too nearing her limit as well if her moans and mewls completed with her love tunnel clamping around her phallus was any indication.

Pinkie's flare swelled, locking her into place within the incredibly wet and tight fucktunnel, and the formerly closed mouth of Mrs. Cake's cervix yawned wider and wider. There was no backing out of it now, Mrs. Cake was about to become a mother twice over.
You, along with the size of the orbs' content were pushed out of it through the sphincter and back to the tubes that swallowed you in incredible sliding speed which helped in the herm mare pleasure and suddenly you were hurled out of the flare along with the reproductive goo of the party giantess, passing the open cervix and landing on something soft, expansive and wet organ. You heard the giantesses moans in delight and felt the place and organ vibrates.

Mrs. Cake and Pinkie moaned and cried out in ecstasy as they came, she fully hilted in letting her party seed fill up the oven of Mrs. Cake, said mare came hard as she felt Pinkie warm seed invades her uterus, chances of her becoming a mother again were very likely now, her very foal canal clamped again and clenched around Pinkie's rod with the intention of milking her more.

However, despite her mind being mush by the orgasm, she was glad to feel you again within her
