Undercover: Lover

Celestia looked around slightly. Ponies were sneaking glances at her. It was embarrassing to walk around outside wearing a bridle. Of course, she was in the form of Silver Glow, but even so it was…

It would be lying though to claim it didn’t make her wet.

“Where are we going?” She asked the griffon next to her.

Zaria smiled at her, “Don’t you worry about that, you just come along and be pretty for me.”

Blushing, Celestia nodded and trotted along as she led her through Canterlot. Thankfully, she led through sections that weren’t too busy.

“In here, pet,” Zaria said and pushed the door to a club open and led her inside. Celestia glanced up at the sign proclaiming to be the ‘Kitten Den’.

An ‘adult’ club.

Swallowing nervously, she trotted in with her. It was mid morning so this place wasn’t exactly packed yet, but there was a dozen ponies there already, drinking and watching the mare dancing on stage wearing a… rather scandalous outfit.

Zaria gave her cheek a nuzzle and purred, “Stay,” and moved over to talk to the mare behind the bar.

Swallowing nervously, Celestia stayed still, glancing around. Most ponies were paying attention to the filly on stage, but a couple of the stallions were watching her now.

Zaria returned and hooked a claw into her bridle, “We’re all set for today, come on, slut.”

Letting her lead her along with the bridle, Celestia followed her mistress around the back before opening a wooden door and leading her into a small room. A kind of room Celestia recognized very well by the well placed hole in one of the walls.

“A gloryhole, mistress?” Celestia asked, eyeing the straps hanging from the ceiling and wall by the hole.

“Not quite,” Zaria said and closed, locking the door, “Now, you can cast illusion spells. I want you to do two, one to cover the hole so nopony can see inside, and one to block sound from this room.”

Celestia nodded, “Yes Mistress,” and quickly cast the two spells.

Zaria smiled and reached up to stroke her ears, “Good filly. Now, turn back for me.”

Celestia hesitated, “I-I…” she hesitated, “I guess nopony can tell…” she admitted and then canceled her spell, returning to her real shape and size, shifting her wings.

Zaria gave her a small kiss, “Now, time for your reward. Back up against the hole, put your cunt against it nice and tight,” before she moved around and pushed away the low bench a normal pony would need to stand on for it to reach.

Blushing darkly, Celestia did as she was told and Zaria started to strap her in place, thick straps going around her thighs to hold her firmly to the wall and stop her from moving, further straps going beneath her waist and barrel from the floor as slings, “Ponies will mount me, mistress?”

Zaria smiled and gave her a small kiss, “No.Ponies and other creatures will fuck they slutty princess. No different from, feeling your real soaking wet cunt around their cocks and pumping you full with their hot cum.”

Celestia blushed darkly, feeling herself winking against the hole, “F-for how long?”

“Until closing time, which is somewhere after midnight” Zaria said and stroked her cheek, “So I hope you can focus enough to lower the sun while being fucked.”

“I-I…” Celestia started, “But… what will you be doing…”

“I will be watching,” Zaria said and gave her another small kiss, “And I brought a couple of books. So just enjoy your reward, my slutty princess.”

With that, Zaria reached to pull a small lever by the wall and there was a thunk from the hole behind Celestia.

It was only a couple of seconds before a cock pressed in through the hole and straight into Celestias dripping wet pussy, causing her to gasp and tremble, tightening. He didn’t pause, starting to thrust from the start.

She moaned softly, trembling against the bonds holding her to the wall.

“Good slut,” Zaria purred and looked into her eyes, stroking her mane, “You love rewarding your ponies for being so good to you, don't you? Wonder who he is… a member of your guard? An administrator? Maybe a shopkeep? Maybe it’s his first time.”

Celestia blushed darkly and pressed back against the wall, moaning and tightening around his thrusts.

Zaria smiled and kissed her gently, “I’m going to slip out for a couple of hours, I have some things I need to arrange.”

“M-mistress!”

“Don’t worry,” Zaria said and nuzzled, “I’m locking the door and I have the only key. Nopony will discover what a slut their princess is.”

Celestia moaned and finally nodded, “Y-yes mistress!”

Zaria pulled back and opened the door a crack, peeking outside before she snuck outside and closed it, locks clicking shut.

Moaning, Celestia half spread her wings as he thrust into her to the hilt, his cocktip flaring and his warm cum flooding into her deepest places.

She gasped at the feeling, trembling against her bonds as he pulled out, leaving her feel suddenly empty.

But she didn’t need to wait long, only some twenty seconds later, another cock thrust into her, a bit narrower this time but longer.

Celestia whinnied softly and tightened around him. He thrust harder but slower, making her moan as his wide median ring slid across her clit at each thrust before her first climax rocked through her body.
