Oh Sister...
Canterlot: Celestia's Chambers: One Week After Luna's Return.
I gave a long sigh, staring down at the pile of papers on my desk. I continued to fill out what work I had been given by the emissaries. A rather droll task considering all that has happened as of late. But I am a princess, life is not all meant to be excitement, I knew this very well.
There was a knock at the door to my chambers. "Come in." I said. The door opened and Luna walked in, bringing a smile to my face.
"Hello sister." Luna said, the same smile forming on her face.
"Hello Luna. What brings you to my chambers?" I asked.
She walked over and sat on the edge of my bed. "I just wanted to talk." She said.
"Of course. A chat would be a nice distraction." I said, happily putting the paperwork aside. I took a seat next to her, crossing my legs on the bed. "What did you wish to talk about?"
She sighed, staring down at the floor. "Things..." She mumbled.
"Oh good... For a second I assumed you wanted to talk about stuff. But things? Thank goodness..." I said jokingly.
Her smile grew slightly and she giggled. "Yes... Things are much simpler than stuff." She said.
I noticed her smile fading, her eyes glistening with sadness. I placed a hand on her arm to reassure her, but she cringed immediately. "Sister... What's wrong?" I asked, sounding a tad concerned.
"I just... Returning to you... This place..." She said quietly, tears streaming down her face.
"Luna..." I said.
"Coming back the way I did... I tried to destroy everything again... I tried to hurt you... Again." She sobbed.
"Luna you have nothing to be sorry for." I said calmly.
"How can you say that? How can... How can you forgive me... Why does everyone accept me.... So easily..." She asked quietly.
"Things have changed Luna. The people of this land are more forgiving than you know. And most of them have forgotten what has happened in those times..." I said, trying to be as soothing as possible.
"I just can't forgive myself..." She said.
"That's enough." I said firmly. She glanced up at me surprised. "Luna you are my sister, and I will always love you... What the public chooses to do is their choice. And if they choose to forgive you, then that is that."
She wrapped her arms around me and the two of us shared a long and warm embrace. "Thank you sister..." Luna said with that returning smile.
"Is there anything else you wanted to talk about? I have the time." I said, glancing at the unappetizing papers still lying inanimate on my desk. I looked back to her and saw her face growing red.
"There... Is one thing." She mumbled.
My smile grew slightly. "What is it?" I asked.
"It's... Not something I take pleasure in speaking of. It's a very... Personal problem." She said hesitantly.
"Come Luna... You can tell me." I said, placing a hand on her leg. Her blush immediately brightened.
"I... You remember... Back before I was banished. The good times... We spent together?" She asked.
"Yes? What about it?" I asked, becoming a little curious.
"When we... Fooled around?" She said, her voice cracking slightly.
My smile faded and turned to surprise as I felt my own face begin to flush. "Yes?" I said in a quieter tone.
"I... I really..." She stammered.
"It's not that I haven't thought about it either dear sister." I said, my heart slightly increasing in pace.
"It's been a long time... Since I felt your skin on mine." She said, still not making eye contact.
"Too long..." I said. My hand slid up her leg and closer to her hip. She let out a small gasp, my smile returning immediately.
"T... There's something else..." She said nervously.
"What is it?" I asked.
"When Nightmare took over... She gave me more than just power." She said meekly.
"What do you mean?" I questioned, my curiosity growing further.
"I... Um..." She stuttered. I gently pulled her into another hug.
"Luna... If you don't want to talk about it then I won't force you to. Just know I am always here for you, and I always will be." I said softly.
"Oh sister I... Stop..." She stammered nervously.
"No. I love you Luna, and I will alwa-" I was stopped as I felt something prodding my stomach. I looked to see a new appendage attached to her... Standing proudly as it throbbed against my abdomen. "Oh..." I mumbled quietly.
"I... I'm sorry." She said quickly.
"Nightmare gave you this?" I asked, taken a bit off guard by the sudden accessory prodding me.
"Yes... It... It hurts very badly." She said.
"Why?" I asked.
"I haven't so much as touched it since before my banishment..." She said.
"And you came to me because you wanted to..." I started.
"Yes..." She nodded.
"I see..." I said. I stared at her pulsating member, a precipitous interest rising quickly inside me. I put a finger on it's head, sliding it slowly to the base. She gripped the bed sheets tightly, closing her eyes tightly.
"S...Sister..." She moaned.
"It's very sensitive isn't it?" I questioned. My own lust had been sparked from the cute moans and pants I could hear escape her mouth as she desperately tried to contain it.
"I... Yes..." She said.
"I think you've been waiting long enough." I said. I stood up and started to strip my clothes off slowly. She watched intently, her breathing quickening.
"I... I forgot how... captivating... your performances were..." She stammered. Her already titanic member seeming to grow even more as it twitched harder. After I finished I stared at her.
"It's going to be difficult with you're clothes on." I said with a coy smile on my face.
She jumped up and started tearing her clothes off. I instantly noticed the extremely swollen sack hanging between her legs. Her balls were the size of basketballs, swinging heavily with each throb of her thick length.
"Oh my... You're really pent up..." I said in utter shock.
"I... I can't wait anymore... Please..." She begged, her whole body shaking with impatience. I could tell she was using every ounce of strength not to pounce on me then and there. I walked up to her, kissing her passionately. Her dick slid in between my thighs, tightly being squeezed as I ground it between my legs. She moaned into my mouth, wrapping her arms around me as my breasts pressed into hers.
I knelt down, licking the tip teasingly and mopping up some of the torrents of pre-cum drooling onto the floor. She started panting. I could see her dick twitch more. I put my hands around it and pulled the first bit of it into my mouth. My tongue made circles around it and my hands started to gently squeeze around the base. Her moans grew louder and I started to bob my head up and down, feeling her slide further into my mouth with each dip. My hands slid down to her balls, rubbing the massive orbs and shivering as I imagined all she had stored in them. As soon as I gripped them I could feel them churning, the pent up need pushing to the surface. I felt her shaft increase in size, her cum building up at the base as I sensed her nearing climax.
"I'm... Cumming!" She bellowed. I felt the first shot enter my mouth, bloating my cheeks out violently. I pulled back and started to cough. Her countless loads splattered against my face, dribbling down my body. I stood up and faced her, smiling widely as I felt her loads start to hit my pussy, the warmth surrounding my clit as it dripped down to the floor. Her orgasm finally died down as she panted heavily. I moved forward and kissed her again, holding the back of her head gently.
I pulled away first, our eyes making contact. A flame ignited in me that I knew only she could feed. I let out a gasp, my eyes widening as I looked down and saw the tip of her penis pressing against the entrance to my pussy.
"I'm... Sorry sister..." She moaned.
"Luna... Wai-" I said as my eyes rolled back, feeling her push into me. I tried to push her back, but she fell forward, the two of us falling onto the bed. She was on top, staring down at me hungrily as her hips started to move. I moaned loudly as I felt each vein rub against the walls of my pussy. I stared down at her thick shaft pounding into me. My pussy was already spasming as I orgasmed, rippling around her as my body did it's best to milk her of all the lust that has been building in her for the countless years she has been alone.
"Oh sister..." She grunted. She grabbed my legs and pushed them up, my knees resting on either side of my head. Her ferocity was increasing and I could feel her growing inside me. She was breathing heavily.
"L...Luna... Stop..." I moaned.
My pleads laid on deaf ears as her pace quickened, her thrusts becoming erratic as her tongue lolled out of her mouth. Worry filled me as I saw her balls start to gurgle and grow even larger.
"Luna please!" I said frantically trying to push her away, but losing more strength with each violent thrust.
"Oh sister... Here it comes... A thousand years of unspent seed!" Luna moaned loudly.
"Sister... Not... Inside!" I said as I felt her dick expand to accommodate the oncoming ocean. My eyes bulged out as I felt the warm liquid flow into me. It felt like I was going to melt, her boiling cum pushing forcefully into my womb, stretching it out with the sheer amount shoving itself into me. She let out a loud moan as she hilted herself into me, more and more of her love shooting in. I let out a cry as my orgasm hit, tightening around her, locking all her pent up need inside me. I felt myself stretching as my stomach started to balloon outward.
"You... Feel so good sister..." Luna said under her voice. When I thought it was finally over, she started thrusting again.
"N... No more..." I moaned.
"Oh god... Here comes another." She screamed as her dick started to twitch violently. I let out a cry of pleasure as she exploded into me, feeling more warmth course through me and bloating out my stomach to ridiculous proportions.
My eyes rolled back and I lost the will to speak, the pleasure shooting through me was too high for my will to overpower.
"Oh dear sister... Our children will be magnificent." She whispered gently, running her hand across my bloating stomach, giggling as it jiggled. "I have so much more to give you..."

The Next Day:
"Sister... Are... You mad at me?" Luna asked.
"Of course not Luna. I know the feeling of not being touched for awhile... What it can do to you. And I can only imagine what a thousand years could have done." I smiled.
"Oh..." Luna said, breathing a sight of relief.
"I'm just glad to see you happy." I laughed.
"Being with you is all I'll ever need dear sister..." Luna said, returning the same warm smile. "But..."
"But?" I questioned.
"Do you think we should get some help?" She asked, poking my oversized abdomen.
"It's strange... Once it goes in, it doesn't want to come out..." I said curiously.
"Well... What do we do now?" Luna asked.
"The day isn't nearly over... And you're still swollen pretty bad." I said, pointing to her large testicles. I laid back against the pillows and spread my legs. "Well? Don't make your sister wait."
Her face lit up, her smile growing, along with certain other parts...
