Slime Pony Smuggler [Clopfic]

"Are you sure this will work?" Night Runner asked nervously, her cheeks flushed with the idea of what they were about to do.

"Don't worry! You've smuggled plenty of stuff before, right?" The gelatinous pony chirped, her smaller form still looking intimidatingly large in Night Runner's eyes. "AND I'll be much easier to hide! They'll just think you're pregnant!"

"And it's safe...? I don't want to burst or anything, y'know..." Runner asked, feeling both terrified and incredibly aroused by what she was about to do.

"Have some faith... I've done this plenty of times before! You'll suffer no ill effects from this..." A slime hoof stroked Runner's cheek gently as the slime pony smiled seductively. "Other than a desire to do it again..."

"Alright... I'm ready..." Runner turned around and nervously lifted her tail, revealing her nether regions to the slime pony.

"I'll say... you're positively soaked. I certainly don't have to worry about drying out while we're on our way." The slime pony leaned in a took a deep scent of Runner's marehood. The smuggling mare shuddered as she felt a tongue slide across her nether lips before plunging itself into her. She couldn't help but moan as the 'tongue' plunged itself in and out of her pussy.

Just as Night Runner was getting used to the preparatory cunnilingus, she let out a small scream as the 'tongue' shot even deeper into to her and spread out into what felt like a a very well endowed stallion rutting deep into her warm pussy.

"T-take it easy, will you?" Runner moaned as the slimy 'cock' slide itself in and out of her folds.

"No." The voice spoke from both inside and behind her, the vibrations traveling through the slime ponies body with ease. Night Runner could only give another moan as the unexpected sensation passed through her body. She could feel every thrust drive a little further than it's backstroke and her belly began to bloat the further it went in.

She could feel her womb fill with it's unexpected passenger and yet, strangely, she could feel no pain from it. She traced a hoof down to her belly and couldn't hide her surprise at how large it had already expanded.

"If you think this is impressive..." The vibrations destroyed any line of thought Night Runner may have had in the interim. "Then wait until we're finished!"

Night Runner's face lowered to the ground as the strength in her front hooves gave out and her hind quarters were supported by the slimy facsimile of a pony behind her. She groaned as she felt her traveling 'companion' began to pick up the pace of her thrusts and her own hindquarters were trying to meet with them. The darkened room was fill with only Night Runner's echoing moans and the wet slapping of slime against pussy. Faster and faster the sound of their mutual thrusts became until Runner felt the familiar vibration of the slime speaking again.

"...time for a big finish!" The vibrations tore through Night Runner's mind like it was wet tissue paper, preventing her from questioning what 'big finish' meant. As her thrusts became more frantic with her on-coming orgasm, she felt the 'shaft' pull back one last time before she felt a massive surge of slime slam through her wanting tunnel. Her orgasmic scream rang out through the room as her hips bucked mindlessly against a lover that was no longer there.

As the last of her energy left her, Night Runner collapsed first to the ground before finding herself unwillingly rolling to the side. Slowly the haze of her orgasm cleared, leaving a warm and contented feeling running through her body. She gasped as she looked down at her distended belly and she had to run a hoof over it just to make sure it was real... she looked positively gravid.

All the more reason why she needed to get into Canterlot, so she could give birth in the much higher end hospitals there... or so her cover story went.

She couldn't wait to do this again...
