With his hands now free, and no longer being pinned down by Fluttershy’s weight, Spike finally had the opportunity to look around the room. Looking down, he realized that the wooden thing he was chained to was a wooden pony mannequin, similar to those Rarity used to display dresses in her boutique. The tip of one of its wooden hooves had broken off, and was lying on the floor underneath, now completely soggy from the messy pool of urine that had spread around the mannequin.

His eyes had also gotten used to the darkness, and he could now see a lot more around him.
Against the wall to his left, he spotted a large cupboard with a transparent glass door. Inside it was a large collection of what he recognized as dildos and strap-ons. He’d never seen one in real-life before, but occasionally when Twilight was out, he would secretly peruse her copy of the “Egghead’s Guide To Sexual Intercourse” and various other questionable texts he’d found stuffed away in various hard to reach places around the library - some of which had pictures in them. The cupboard also contained various other, rather inventive looking implements - also sex toys, he presumed, though their precise purpose was a mystery to him.

Leaning against the wall at the far end of the room in front of him were several large sacks. He could barely make out the words “FLOUR” printed on them. By the looks of it, the room also doubled as a store-room.

Suddenly, a loud noise erupted as he felt the mannequin tremble under him, snapping him out of his thoughts. He turned to see a dark blue hoof connecting with the wooden mannequin a few inches away from his arm. The hoof was equipped with some sort of metal-reinforced leather boot, and several blunt iron nails protruding from its sole had dented the wooden surface.
His gaze followed the leg upwards, until he found himself looking directly into the face of Mistress Moon staring down at him, a look of anger in her eyes. A mixed sensation of fear and arousal shot through his body as he beheld in awe the regal alicorn towering over him.

The look in her eyes told him that he was as dirt, unworthy of her attention. “SLAVE! THOU SHALT LICK OUR ROYAL BOOT!”, her Traditional Royal Canterlot Voice reverberated through the room, causing the wooden mannequin to shake under him. Without hesitating, he leaned over her boot, and sticking his tongue out a bit, licked her boot. It tasted salty, with a just hint of blood. He lifted his gaze once more to look into her eyes for confirmation.

She said nothing, but her eyes told him to continue. He licked the boot again, slowly savouring the taste. It didn’t exactly taste good, but he’d tasted worse - once he was helping Rarity at her boutique, Sweetie Belle had been allowed to prepare dinner, as Rarity had a deadline to make. He wasn’t sure what it was supposed to be, but he still remembered vividly the pungent taste of charcoal and rotten fish - or at least what he imagined rotten fish would taste like if eaten - as he ate his first and last forkful of it. Even the water in his glass had been charred - he wasn’t even sure how that was possible - and he’d had to run to the bathroom to puke and rinse out his mouth.

His mind returned to the present. Thinking back at Sweetie Belle’s cooking, the filth on Mistress Moon’s boot seemed rather appetizing in comparison. He continued to lick until the taste had almost faded away completely, before once again looking up at his Mistress.

“ENOUGH!” her voice boomed. Lifting her boot from its resting position, she jumped onto the wooden pony with surprising agility, and positioning herself upright, shoved her crotch into his face.

He now got to experience another feature on her leather suit - several blunt metal nails similar to those under the boots were located around the hole in the crotch, and were now pressing against his face. They were too short and blunt to puncture his skin, but sufficiently pointy to cause minor pain and discomfort.

“PLEASURE US!” her voice commanded.

He placed his hands on her flanks, and focusing his gaze on the dark blue furry slit in front of him, stuck his tongue out once more to give it a lick. As his tongue slid between her lips, he felt her body twitch with a shiver of pleasure. Remembering a particularly interesting picture he’d seen in a book about female pony anatomy he had once read, he searched the royal mound with his tongue until it located a small bump. As his tongue hit the bump, her body twitched again, a slight gasp escaped her mouth, and her flanks clenched down on him harder.
His tongue continued to dance over her clitoris, as she started riding his face, pressing down harder and harder as pleasure was building up in her body. The nails digging into his face were hurting a bit now, but he continued to lick, knowing that the sooner he made her climax, the sooner she would release her grip.

Finally, a loud moan escaped her mouth as she came, clamping her flanks down on him, and grinding her crotch into his face hard. The force of her squeezing down on him caused one of the nails in her crotch to puncture his skin, and a small drop of blood trickled down his face.

He continued to lick her slit while she came, feeling the convulsions with his tongue as he lapped up her sweet marely juices.

Quickly recovering from the orgasm, she lifted herself off his face, preparing to reposition herself.

As he let go of her flanks, and lifted his arm to wipe away the blood from his face, he realized that his arms, as well as most of his lower body were still smeared with Fluttershy’s blood.

“THOU SHALT NOW PENETRATE US WITH THINE MANLY STAFF!” she shouted, positioning herself over his penis.

He raised an eyebrow at the cheesy line. “Manly staff?” he thought. “Surely she could come up with something better than that...”. This line of thought was quickly interrupted, however, when he felt her warm wet cunt sliding onto his joystick. Shivers of pleasure shot through his body as the royal vagina caressed his rod.

She wrapped her long legs around the wooden pony and started thrusting, grinding her groin against his. With each thrust he felt her wet furry cuntlips rubbing against his balls, and the blunt nails pricking his hips. He knew he wouldn’t last long like this, and bit his lips to hold off from coming too soon. Her thrusting became faster and harder as she became more aroused, and her moans louder.

Suddenly, she opened her eyes and stared down at him, grinning. “WE URGENTLY REQUIRE RELIEVING OF THE ROYAL BLADDER!” she screamed in the Traditional Royal Canterlot Voice, “THOU SHALT BE OUR TOILET, SLAVE!”.

He knew what was coming, but the force with which it came took him by surprise. A flood of dark yellow liquid erupted from the royal peehole with the force of a waterfall, pushing its way out around his cock and spraying all over the place. The warm wet sensation against his dick, and the wet squishy sounds of her continued thrusting as the royal wee flowed down his body pushed him over the edge, and he came with the force of a thousand elephants.

“YES!” she screamed, her eyes shining blue, as he pumped his thick goo into her, and she too came with great force. Still urinating profusely, her royal cunt convulsed around his throbbing member, milking it for all it was worth. Their orgasms seemed to go on for minutes, constantly renewed by the flow of pee, before the flow diminished into a trickle, and then stopped completely.

After their orgasms subsided, she was leaning over him, gasping, her body covered in sweat.

“That was... intense.” she said, a tone of exhaustion in her voice, and apparently having forgotten all about the Traditional Royal Canterlot Voice and The Royal We. She slid off his now flaccid cock and back onto the floor, making a splashing noise as her hooves landed in the puddle of urine, thick white dragon jizz oozing from her plot as she walked away.
