During the walk to Chocolate Cherry's home, she and Nightmare Moon became affectionate towards each other. The pair would press against each other at the shoulder or flank. Cherry would nuzzle at Nightmare's neck or cheek, and Nightmare would nip at Cherry's jaw or ear. Occasionally, Nightmare Moon would trace the very tip of her wing feather along Chocolate Cherry's spine.

Nightmare Moon found the act rather pleasant. It surprised her how much she enjoyed touching a pony, and having a pony touch her. Even if it was not sexual, it was intimate. Although she would never admit it aloud, she did enjoy it and wished for more.

Would she enjoy it as much with a stallion? It was something for her to consider and possibly explore at a later time.

After some more walking, the pair managed to reach a house, where Chocolate Cherry turned and headed for the door.

"Okay," she whispered as she grabbed the knob, "we need to be quiet. I have a roommate and he's probably asleep right now. We don't want to wake him up."

Grinning, Nightmare Moon leaned in close until her mouth almost touched Chocolate Cherry's ear.

"And why not? Perhaps if we do, we could get him to... join... us." She then gave the ear a nip, letting out a low growl.

"Sorry to disappoint you," Cherry said with a giggle, "but he's not interested in mares. Maybe some other time, you can get some tips... or maybe convince him to let you use an 'artificial penis' on him." This last part was followed by full laughter as she opened the door and stepped inside.

Nightmare Moon let out a snort (her warm breath tickling the sensitive hairs of the other pony's ear) and rolled her eyes, but said nothing. How was she to know that they were called "dildos?" Luna had not even been familiar with the toys when they were in control, and Nightmare really had no interest in them to begin with. Nightmare had learned of them while working to inhabit Rarity, who had a rather large one in her possession. Even then, Nightmare really did not care about it, although the fantasies that Rarity had while using it were interesting.

The two made their way in, with Nightmare Moon shutting the door behind them. She followed after Chocolate Cherry, keeping close. Nightmare did not pay much attention to the dark house, most of her attention on the feminine butt in front of her, watching the movement of the tail and trying to get a glimpse of Cherry's vaginal opening.

At the door to the bedroom, Cherry stepped aside and motioned with a hoof.

"After you," she said.

Nightmare stepped into the room, looking around as she headed for the bed. There were a few painting hanging on the wall, one of which was of her just after her return. The bed was, sinking under their weight as they climbed onto it. It was also permeated with Chocolate Cherry's scent. On the nightstand were two books, an alarm clock, a large glass bottle with a candle in it, and a bit-sized disk with "1 YEAR" written on it.

"What is that?" Nightmare asked, looking at the disk.

"Sobriety chip," Cherry answered as she reached for the nightstand and pulled open a drawer. "Long story, but it reached the point where I was waking up from being black out drunk with somepony else in my bed that I don't even remember... or ponies... and once a griffon.." She paused, turning to face. "You aren't, are you? Can you even get drunk? Maybe I should have as--" Once again, she was stopped by a hoof against her mouth.

"I have never imbibed alcohol before tonight," Nightmare stated, "and I do believe it has effected me. I assure you, however, I am sufficiently in controls of my faculties despite the inebriation that this is certainly something I want." Leaning forward, she kissed Chocolate Cherry again, until the kiss was reluctantly broken.

"I guess if you can say all that so coherently, you're still pretty sober," Cherry decided aloud. She turned back to the drawer. "I just need to grab some things. Starting with this."

Nightmare looked at what Chocolate Cherry now held out to her. It was a length of leather that was meant to be made into a circle. The outside was a smooth and shiny black while the inside looked to be soft. There was a buckle and holes to adjust the size, and a ring that stuck out.

"A collar?" Nightmare asked as she looked at it. "Do you expect me to put this on?"

"On me," Cherry replied. "Sex slave, servant, toy, hoof-maiden, whatever you want to call it. Put it on me, and tell me to do whatever you want me to."

"Why?" Nightmare asked. She had not expected to be offered such a thing.

"Because I like being submissive. Because I know you like being in charge and control. Because I like the idea of worshiping and pleasing you."

Well, Nightmare did like the idea of being worshiped, pleased, and obeyed. Having a pony that was would do so was nice, and the fact it was willingly amused her.

It was willing. That was the part that was sticking in her mind a little. This mare barely knew her, just a few hours together and a brief appearance from when first arrived and tried to take over Equestria. Yet here Cherry was, trusting Nightmare enough to be her slave and do whatever she desired. Well... probably not whatever. There was nothing she could do if disobeyed, except maybe bite or spank. Although, Chocolate Cherry very well might be into that. Then again, she might as well.

That was getting off topic, and something that could be explored later.

"Very well," Nightmare decided. "I shall allow you to be my..." she considered the terms that had been used "...'bound hoof-maiden' for the night." With that -- and some guidance -- she placed the collar around Chocolate Cherry's neck.

"What do you wish of me, my mistress?" Cherry asked, bowing her head. She shifted, a smile tugging at her lips as she tried to look serious.

With a grin of her own, Nightmare Moon leaned back on the bed and spread her hind legs.

"You said you like the idea of worshiping and pleasing me." She ran a hoof down her stomach to her crotch. "So you should start by doing so properly."

Leaning down, Chocolate Cherry brought her head between Nightmare's thighs. Cherry kissed the inside of the leg gently, causing a strange tingle of pleasure. It was followed by another, and another, moving further up the inside of the thigh.

A sudden nip caused Nightmare to tense, her leg kicking as she let out a gasp of pleasure. Eyes wide and ears pulled back, she watched as Cherry moved closer to her vagina. Reaching out, Nightmare placed a hoof on top of Cherry's head and rubbed at the base of the ears.

This seemed to be taken as some sort of sign of encouragement. Cherry continued to nip and kiss, working her way up the thigh. Reaching the inside of the joint, she stuck the tip of her tongue out and traced along it. She then moved to Nightmare's vaginal lips, tracing along them as well.

The feel of a pony's tongue along her sex was interesting to Nightmare, and felt nice. It was when the tongue hit the sensitive nub of her clitoris that a bolt of pleasure shot through her. A second lick caused her to gasp out as the bolt seemed to grow more intense. It was so pleasurable it was almost painful.

As Cherry's tongue moved from licking the sensitive nub directly to tracing around it, the excessive pleasure passed. It was replaced by a weaker one, but one that built up with each stroke. A slow building pleasure that grew stronger and stronger. The entire thing was almost teasing, but felt wonderful.

Finally, something in Nightmare Moon reached her limit. A cry of pleasure escaped her as she did, throwing her head back. Her body tensed as the feeling pulsed through her, sending bolts into every part of her. As it came to an end, Nightmare went limp, falling backwards onto the bed and panting.

"Are you okay?" Cherry asked, looking up from between Nightmare's hind legs.

"That was... extremely pleasurable," Nightmare replied, staring up at the ceiling. It was amazing. She had just experienced an orgasm. Her first ever in fact. And by a pony no less. She definitely wanted to experience something like that again. Although not right this minute.

However...

"Turn around," she ordered.

Slowly, Chocolate Cherry got up and turned around. As soon as she did, Nightmare grabbed her and pulled Cherry closer, getting a small squeak of surprise. It was a cute noise.

It was also a cute butt. Round and thick, reminding Nightmare of Cherry's namesake fruit with the patch of dark brown around the vagina looking similar to her first name. If it actually had been a cherry, Nightmare would have described it as "juicy." Nightmare wanted to just take a bite of it.

So she did.

Not hard enough to break the skin, she was certain of that. It was, however hard enough to get another squeak from Cherry, followed by a long moan of pleasure. Leaning a little further, Nightmare slipped her tongue out of her mouth and pressed it against the cutie mark, giving it a long slow lick. It tasted neither like chocolate nor cherries, but Nightmare found herself enjoying it all the same.

"Please, Mistress," Chocolate Cherry whimpered, "please bite me again." She wiggled her hips, causing her backside to sway in front of Nightmare's face rubbing against it.

That was an interesting and unexpected reaction. It was also one that she was proud of. It meant that Nightmare had done it right: the bite was firm enough to be felt and get a reaction, but not hard enough to be painful.

For a moment, Nightmare considered not doing what Cherry begged her to. After all, she was supposed to be the one in control. Still, she had enjoyed what Cherry had done earlier, and it was fun to bite that butt. Especially with the noise the mare made. So Nightmare Moon bit Chocolate Cherry again. And again. And again. Each time moving a little closer to the other mare's crotch, and each time getting a little squeak and a moan in response.

Reaching Cherry's privates, Nightmare slipped her tongue out once more. Pressing it to the outer edge of the brown patch, she traced slowly down with just the tip touching. She gave one last nip before pulling away, but just barely. Moving, she let her mouth stop just above Cherry's clitoris, letting her hot, moist breath blow against the sensitive spot each time she exhaled. Just a slight push forward by Nightmare or back by Cherry, and the two would touch.

"Tell me," Nightmare Moon purred out. "Tell me how much you want it."

"Please, Mistress," Cherry cried out. "Please touch my privates. Allow me to cum. I want to so badly. Please. I'll do anything if you let me cum."

"Then perhaps you should start licking again," Nightmare stated.

Taking her cue, Chocolate Cherry did just that. Lowering her head, she pressed her mouth against Nightmare's sex once more as she began to lick again. Her flicked over the sensitive nub of the clit before sliding around to tease the edges of it, sending new sparks of pleasure through Nightmare's body. After letting out a moan, she pulled Cherry closer to begin licking as well.

Closing her eyes, Nightmare tried to mimic Cherry's movement. Her ears twitched as she listened, trying to pick up on what Cherry reacted, and what seemed to work as encouragement, giving Nightmare Moon more pleasure. She gave quick, tentative flicks over the sensitive nub, causing quick whimpers and the rump in her grip to tense slightly. She was careful not to do it too much, remembering how intense it was for her. In between, she would trace slow, gentle circles around the edges.

As she looked at Cherry's vagina, Nightmare became curious. Moving her head up, she traced the tip of her tongue along Cherry's vaginal lips, feeling a shift in the mare in response. Taking this as a sign of encouragement, gave it another lick. Her tongue pushed forward more, parting the lips and beginning to sink in.

As she continued to push deeper and deeper into Cherry, Nightmare realized that something similar was being done to her. She could feel the tongue slipping inside her, teasing at her folds... and something else. It felt different from the earlier experiences. No where near as intense as when her clitoris was directly licked, nor as pleasurable as the teasing around it. It did still pleasant, however, and Nightmare could still feel herself building up to another orgasm.

The two continued to lick and nuzzle each other, facial lips pressing against vaginal. Nightmare's tongue pushing deeper and deeper to lick along the walls and probe the depths. Cherry's teasing along the nether lips and slipping just inside before pulling back again. Both even shifted the way they laid, their chins rubbing against the tips of the others' clit to send additional thrills through their bodies.

From what Nightmare could tell, Cherry reached her climax first. Her hooves pressed down on Nightmare's flanks more as Cherry let out a massive cry of pleasure. The walls of Cherry's depths tensed and flexed, squeezing against Nightmare's tongue and coating it with the taste of feminine fluids.

As the climax subsided, Chocolate Cherry resumed her licking with a renewed excitement. So much so that Nightmare ended up experiencing the second one in her life, seemingly as soon as Cherry's had stopped. When it came to an end, Nightmare collapsed, staring up at the ceiling and panting.

"I think I have had enough," she said as she tried to catch her breath.

"Did I do well, mistress?" Chocolate Cherry asked, turning around to face Nightmare Moon.

"Very," Nightmare Moon responded before yawning. "So much so that I believe my body is telling me that I require sleep. Now come." She opened her forelegs. "You mistress demands cuddles as she sleeps."

Where had that come from? Nightmare Moon knew that she had said it, but did not recall thinking about it. She was not a "cuddly" pony. Bad enough she was a pony, but she did not want to be some soft, friendly, affectionate type.

Alternatively, Chocolate Cherry had done a good job and did deserve some sort of reward for her performance. Plus, it was Cherry's bed, and Nightmare had no real authority (as much as she hated to admit it). So if she wanted, Cherry could just as easily kick Nightmare Moon out of bed if she so wished (actually, since she was an earth pony, Cherry could probably kick Nightmare out of bed quite literally). That considered, it was probably better to offer an opportunity to cuddle seemingly as a reward and keep in control.

Nightmare mentally applauded her own brilliance, even with the limitation of her inebriation and post sex euphoric exhaustion.

The look on Chocolate Cherry's face as she moved to lie down beside Nightmare Moon showed that the ploy had been an effective one. Smiling broadly, Cherry pressed herself into Nightmare's side, setting her head and one foreleg onto the large pegasus mare's barrel. The red mare let out a small noise of contentment as she rubbed her cheek into soft fur. Soon as she did, Cherry closed her eyes, seeming to go completely limp and falling asleep instantly.

Nightmare Moon laid there for a moment, looking down at Cherry and wrapping a wing around her. A large part of Nightmare like this: the feel of another pony cuddled up against her; the warmth of the body heat; the softness of the coat; the gentle weight on her chest; the sound of gentle breathing reaching her ears. It was nice. Not that she would admit it to anypony... any other pony... Twilight and her friends.

A small smile spread across Nightmare's face as she watched Cherry sleep before dozing off herself.
