1,000 Years Ago

Celestia’s room had been closer. By that point neither of them cared what room they were in so long as they were together and had their privacy. So as soon as her bedroom doors came into view they hurried inside as quickly as they could. As soon as the door was shut behind them, Celestia pushed her sister against the other side of the closed door and kissed her as passionately as she could muster. She was afraid that she was being too aggressive, but Luna gave no signs of that so she continued. After a few moments, Luna broke the kiss and looked into her sister’s eyes.

“Let’s take a bath.” She said quickly.

“Good idea.” Celestia said, backing away and slipping into her bathroom quickly.

Luna’s heart beat rapidly in her chest and she was breathing heavily, trying to recover from the passionate advances of her sister. She heard the water start to run as her sister began to draw a bath. She looked around the corner curiously and watched in awe as Celestia removed her regalia and set them on the counter. She was absolutely beautiful. She didn’t understand how she hadn’t seen it before. Her flowing mane, her gorgeous white coat, her perfectly proportioned face – it was all perfect. She was perfect.

Feeling her sister’s gaze, Celestia turned back to look at her sister as she stood in the bathroom doorway.

“You coming Luna?” She asked, stepping into the tub.

Luna rushed to remove her own regalia before stepping inside the tub with her sister. Celestia had laid down on her back and was taking up most of the room in the tub. She patted her chest and gestured for Luna to lay on top of her. She was more than happy to oblige and embraced her sister tightly as she laid on top of her, rubbing her face against the soft fur of her sister’s chest.

“You feel nice sister.” She said simply.

Celestia said nothing as she began kissing her chest, causing the white alicorn to jerk in pleasure at the sensation. Luna began kissing upwards along her chest and neck before reaching up and licking her cheek affectionately. Celestia moved and brought her muzzle against her little sister’s, pressing against her enthusiastically. Luna opened her mouth to allow her sister access.

Celestia had been waiting for her to do that of her own accord. She knew that her sister was very inexperienced and didn’t know what to do. She knew that she had to take it slow so she wouldn’t overwhelm her. But now that she had given her access, she took full advantage of the opportunity to show her what a real French kiss was like. She brought her tongue along Luna’s, easily dominating it. The sensation was totally new to Luna. It was a little weird at first, but she eased into it, allowing her sister to take the lead.

As Celestia broke the kiss, Luna licked her lips sensually, eager for more. Overwhelmed with emotion, Celestia buried her face in her sister’s neck and nibbled gently, causing her to moan at the sensation.

By that time the tub was already too full. Celestia reluctantly used her magic to turn off the knob and pull out the plug to lower the water level. Luna had been too distracted and was still coming off her emotional high so she hadn’t noticed how high the water level had gotten. She shifted in the tub, causing a bit of water to spill over the side. The sound of water splashing on the floor brought her back to reality and she realized just how out of hoof things had gotten.

“I-I guess we should get ourselves cleaned up.” She said. “We didn’t get in the bath to get even dirtier, did we?”

Celestia laughed.

“Agreed, little sister.” She said. “Now let’s wash that back of yours.”

Celestia turned her sister over so that she was facing away from her, grabbed a soapy sponge and began washing her sister’s back. Luna blushed as chills went up her spine from her sister’s ministrations. By now the water level was below half and Celestia casually put the plug back in with her magic as she went up and down her sister’s back with the sponge.

Luna could tell that she was almost done, but she didn’t want the sensations to stop. She liked the feeling of being washed.

“S-sister…?” She asked. “Could you wash my…front too?”

She nearly “eeped” in surprise as she felt her sister’s body press up against her back as she brought her hoof around her body. She rubbed the sponge up and down her sister’s front, eliciting a few moans of pleasure from her. She got lower and lower with each pass until she was passing the sponge over her sister’s clit casually with each downward and upward stroke. She felt her sister stiffen each time she brought the sponge along her clit and watched as Luna bit her lip each time, trying not to cry out.

Luna’s blush covered her entire face as she experienced the guilty pleasure of getting off to her sister washing her. Feeling emboldened, Celestia focused mostly on her lower region, passing over her clit more frequently as she circled around her lower abdomen. Eventually all attempts at subtlety were abandoned as Celestia ground the sponge against her sister’s marehood in a rhythmic motion with the sole intent of getting her off. It didn’t take long before Luna let out a loud moan. On instinct Luna tried to stand up as she experienced her orgasm, trying to get away from the overwhelming sensation of the sponge against her marehood. But Celestia held her down forcefully and continued rubbing the sponge against her, bringing her to new heights as she her spasming body tried to buck her sister off.

“Oh sister…Ahhh!” She exclaimed, shaking in ecstasy as jolts of pleasure shot through her entire body.

Celestia grinned as she held her sister down, intent on giving her an amazing orgasm. After a few moments, Luna settled down and looked back at her.

“You’re so cute when you cum.” Celestia observed.

Luna blushed profusely. She’d never heard her sister use vulgarity like that before.

“There’s nothing sweeter to me than your moans of pleasure, or your spasming body as I bring you over the edge.” Celestia said. “Nothing.”

“B-but what about you?” Luna asked.

“I told you before Luna, my pleasure is secondary to yours.” She said. “All I want to focus on is you until you get more comfortable with this.”

That didn’t sound fair to Luna, but the look of sincerity in her sister’s eyes made her feel a little better.

“Now,” Celestia said, changing the subject. “You’re certainly clean, but I’m not. Mind washing my back for me?”

Both princesses were drying themselves off with their towels after getting out of the bathtub. Luna started drying off her mane, draping the towel over her head and blocking out the rest of the world as she dried herself as best she could. She jumped in surprise as she felt her sister on her back. Celestia grabbed her towel with her teeth before pulling it off of her slowly and letting it fall to the floor. She started gently nibbling on Luna’s ear, the sounds of her husky breathing signifying her arousal. Luna looked at their reflection in the mirror and blushed at the clearly erotic scene in front of her. Her sister had a look of sly arousal on her face as she nibbled on her ear sensually.

“Sister…” Luna said, turning her head upward and moaning softly. “Sister…I need to get dry…”

“I fail to see why.” Celestia said, smirking. “You’re certainly not going to stay dry.”

Luna lowered her front half as she tried to shrink away from her sister’s ministrations. Celestia followed her to the floor, not wanting her prey to escape. Luna felt hot – so hot and aroused. But she also felt dominated and powerless by her sister’s aggressive advances.

“Sister…please…stop…” She pleaded quietly, feeling very vulnerable.

Realizing that she might have gotten lost in the heat of the moment, Celestia backed off her sister immediately.

“I’m sorry Luna.” She said. “I let my emotions get the better of me.”

“It’s okay.” She said, feeling better now that her sister was no longer towering over her. “I just…you’re being very aggressive sister. I’m not used to it.”

“I would never hurt you Luna.” She said, a look of tenderness in her eyes.

“I-I know.” She said. “It’s just…really overwhelming to be the focal point of all your desires like that.”

“I will try to suppress my desires for you Luna.” She said. “But it’s getting harder and harder each time we’re alone together.”

“No, don’t suppress them!” Luna said frantically. “You just have to go slower.”

“I’ll try.” Celestia said confidently.

“I’m sorry I’m so skittish sister.” She said. “I know you want more from me, but I just…”

“No Luna, I’m the one in the wrong.” She said sadly. “I need to go at your pace. I don’t expect you to catch up to mine.”

“You’re ready for more.” She observed.

“But you’re not.” Celestia said quickly. “I don’t care if we ever make it past this point. I’m just glad that you know how I feel about you and I can love you freely without having to distance myself from you anymore.”

Luna looked away from her, blushing.

“Y-you touched me…” She said matter-of-factly.

“I’m sorry if I crossed the line Luna.” She said. “But you didn’t give any indications that you wanted me to stop.”

“No, I didn’t want you to stop!” Luna exclaimed, not wanting her to misinterpret her statement as an accusation. “I really enjoyed it. It was just…unexpected. I was caught up in the heat of the moment and now that I’m looking back, I realize that you just…masturbated me sister…”

Celestia stood there silently, not knowing what to say.

“Nopony has ever touched me before…” Luna continued. “I never imagined that you would touch me like that sister. Our relationship has changed.”

“Is that…bad?” Celestia asked, fearing the answer.

“No, it’s just different.” Luna said, looking up at her. “You may have felt this way about me for a thousand years, but I’m just now coming to terms with how I feel about you sister. You have to be patient.”

“I would wait for you forever Luna.” She said. “I love you more than anything in this world.”

Luna put a hoof to her chest, breathing deeply.

“You know, it’s funny.” She said. “On one hoof, I really liked you touching me and I want you to do it again, but on the other…”

There was a long silence between them as she collected her thoughts.

“What is it Luna?” Celestia asked, looking at her in concern.

“I…I’m afraid…” She admitted, blushing in embarrassment.

“Afraid?” Celestia asked in surprise.

“Y-yes…” She said. “I’m afraid of having sex. I’ve never done it before. I don’t know what I’m doing and I don’t like not being in control of my body… And on top of all that I’m having sex with a mare when I don’t even like mares! And I’m afraid of disappointing you sister. I’ve looked up to you all my life and I don’t want to let you down… I just…”

“Shhhhhh…” Celestia said, embracing her sister in a tight hug. She looked down at her with a look of sympathy and guilt.

“It’s okay Luna.” She said. “I’m sorry for pushing you so fast. I had no idea you were struggling with these fears. I just…my love for you is so strong that it’s blinding me to the plight of the one I love most. But no more. Luna…let’s agree to never have sex…”

“What?!” She exclaimed frantically.

Suddenly she felt intense worry, which confused her greatly. Here she was saying how afraid she was of having sex, but the mere thought of never being able to have sex with her sister filled her with an even greater sense of worry and fear.

“I don’t need sex in order to be happy in my relationship with you Luna.” She explained. “You’re my sister, and my love for you is much more powerful than my body’s urges. And I guess we’re not technically committing incest if we abstain from sex, regardless of how much we kiss…”

“N-no!” Luna exclaimed. “Sister…I want to have sex with you! I do! It’s just…your aggressiveness is scaring me even more than I already was…”

“Oh Luna, I don’t mean to scare you.” She said sadly. “I just want to give you as much pleasure as I possibly can. From now on Luna, that is my main purpose in life. I want you to feel my love flowing into you.”

Luna didn’t know how to respond to that. Her sister was being completely and totally selfless. She didn’t feel guilty, but wanted to give her something as well.

“S-sister…let’s have sex...” She said, blushing and turning her head slightly, avoiding her sister’s gaze. “You’ve wanted it for so long and I want to give it to you. I just…need you to go slow. I’ve never done this before…”

Celestia looked down at her sister in surprise.

“Luna, I - ”

“Please sister, let me give this to you…” She said, looking up at her sister with pleading eyes.

“No, Luna.” She said firmly. “I don’t want you to have sex just for me. As much as I want you, if we’re going to have sex then I want it to be on your terms, not mine.”

“It’s not just for you!” Luna said, stamping her hoof on the tile floor. “I want to! I just need you to go slow for me and not be so aggressive. I-It scares me…”

“Why does it scare you Luna?”

“Nopony has ever…wanted me like that.” She explained. “Your desires for me are so strong and I know how much you want me, and I don’t want to say no to you because you’re my sister and I love you. But I feel like I don’t have any control. I know you would stop if I asked you to, but I don’t want to lead you up to it just to make you stop right in the middle of it. I-I feel like such a tease…”

“You’re not a tease Luna.” Celestia said reassuringly. “You’re just scared. But you’re not just afraid of having sex. You’re also afraid of rejecting me. But Luna, wanting to stop isn’t rejecting me. You’re my sister and I love you. I wouldn’t want to go through with it if you were uncomfortable. No matter how aroused I was, your comfort is much more important to me.”

“T-thank you sister.” She said, sighing.

“Now, how about we have some lunch?” Celestia suggested. “Room service?”

“That would be lovely.” Luna said, smiling.
