The Princess of the Moon, Princess Luna, had been locked within the moon for 1000 Years. Upon her return, she resumed her plans as Nightmare Moon to take over all of Equestria, shrouding it in eternal night. However, 6 ponies, together with the Magic of Friendship used the Elements of Harmony to defeat Nightmare Moon, eradicating all the evil within her heart, leaving only Princess Luna.
Upon returning to the Canterlot Castle, Princess Celestia set up a room for her little sister. As soon as Celestia lowered the sun, she guides her sister to her new room, opening the door to reveal it. Luna walks in carefully as she looks around. The walls and decor are moon and night themed. "I hope the room is to your liking." Celestia says, walking up behind Luna.
Luna looks around, unsure.
"We should both get some rest. After today's affairs." Celestia says as she turns around, still keeping an eye on Luna.
Luna is hesitant to continue forward in the room, looking around nervously.
Celestia immediately takes notice as she turns back in the direction of her little sister, "Is something the matter, sister?"
Luna looks down shamefully, "I've spent 1000 years alone. Night after night sleeping all by myself, with nopony around. I don't want to be alone again."
Celestia's eyes widen. She realizes the loneliness her sister must have been in for all those years. And then she remembers the loneliness that she herself has had for all those years.
Celestia smiles, leaning down to her sister, "Would you feel better if I slept with you, tonight?"
Luna looks up at her big sister before darting her eyes away and nodding in embarrassment.
Celestia stands tall as she walks out of the way of the door. Using her magic, she gently closes the door, locking it behind her. She walks to the dresser and proceeds to start taking off her regalia.
Luna looks down at her own regalia and uses her magic to begin taking it off.
Once Celestia finishes, she proceeds to get onto the bed and lay on the sheets. The Princess watches as her sister takes off her Royal regalia, finishihg with her crown, which she sets on the dresser. Luna looks to her sister, who's smiling expectantly. Luna looks at the ground as she approaches the bed and climbs into it, laying next to her sister. Celestia smiles passionately at Luna, giving Luna a nervous, yet endeared feeling. Luna looks down, intimidated by the eye contact of her older, more authoritative sister. Celestia brings her hoof to her sister's chin and gently raises it, forcing eye contact between the two. "I've missed you so much, little sister." Princess Celestia says.
Luna curls a small smile, "I've missed you too."
"Do you remember what we used to do when we would sleep together?" Celestia asks as she takes her hoof off Luna's chin.
Luna looks away to think for a moment. Luna goes wide-eyed and turns back to Celestia, "You don't mean-?"
Celestia closes her eyes and nods with a smile.
Luna turns her head away, "Are you sure you want to do that with me? After what happened?"
Celestia leans her head close to Luna's, "Oh, Luna, it's been 1000 years. I haven't done it in so long. Of course I want to."
Luna is taken aback by her sister's words, "You…never did it with another pony?"
"Nopony could ever replace the love I feel for my sister." Celestia says, leaning into Luna and kissing her on the lips. The kiss is only surface level, simply the pressing of the two sisters' lips together. Luna's wings flap open in response to this. Celestia ends the quick peck of a kiss, leaving her little sister with red cheeks.
The initial shock subsides as Luna begins to realize that she wants more. She stares longingly into Celestia's eyes until she can no longer bear it and quickly pushes herself forward to kiss her sister deeply. This time, their mouths caress each other openly. The two sisters close their eyes as they embrace the kiss. Celestia nearly ends the kiss before it's restarted by Luna forcing her lips back onto her older sister's. 1000 years of loneliness and solitude has festered in Luna longing to kiss her sister for hours on end. But alas, the kiss must end; and Celestia firmly, yet gently, pulls out of the kiss.
Luna stares longingly at her sister, eagerly wishing to return to that passionate feeling. Celestia chuckles at her little sister's eagerness, "Easy, little sister. I'm just as excited as you. But give me a chance to catch my breath."
"It's just been so long." Luna says as she leans her neck into her sister's, closing her eyes and embracing the feeling of Celestia's heavenly soft coat.
Celestia leans her head down, caressing her neck against her sister's with passionate expression, "You're so cute, Luna."
Luna smiles as she snuggles in closer to her sister.
Celestia leans her head close to Luna's ear and speaks in a gentle voice, "I have an idea."
Luna opens her eyes and takes her neck off her sister. She looks up at her with curious eyes.
Celestia leans closely to Luna's ear and whispers, "Lay on your back."
Luna pauses for a second as she looks at Celestia, who's giving her a passionate smile.
Luna, as Celestia requested, carefully lays down on her back, exposing her belly submissively. Celestia carefully crawls over her sister and stares deeply into her eyes, building up suspense in Luna's fragile mind. Celestia slowly leans forward and kisses her little sister, reigniting the feeling of security and love that Luna so desperately desires. Luna pushes strongly against her sister, like a hungry animal desperate to get food, Luna kisses her sister, desperate for her love.
After a moment, Celestia finally ends the kiss, leaving Luna silently frustrated. Celestia notices her little sister's frustration and smiles. She leans in and kisses Luna on the cheek. She quickly takes her mouth off and kisses again in a different spot. Luna tilts her head, giving Celestia a better angle. Celestia takes this opportunity to plant more heartfelt kisses on her little sister. Celestia carefully moves down to her sister's neck, planting even more kisses. Luna closes her eyes and leans her head back, exposing her neck more. Seemingly as soon as Luna does this, Celestia starts descending down Luna's body.
Celestia makes it past Luna's chest, down to her belly, and finally stopping at her teats. Celestia stops her bombardment of kisses and rubs her cheek against the soft tissue of her sister's mammary glands. She darts her eyes up to see that Luna is waiting expectantly for her to do something. Celestia looks down at Luna's teats before she plunges her mouth onto the left one. Luna's mouth goes agape as she watches her older sister gently suck on her teat. Luna, unlike her sister, has quite small teats; small enough to completely fit in Celestia's mouth.
Celestia sucks ever so gently on her little sister's teat, circling her tongue around the nipple gently. Luna closes one of her eyes in pleasure as Celestia pleasures her. Celestia gives a gentle bite on Luna's nipple, prompting a small moan to escape the pony's mouth. Celestia slowly begins grinding her little sister's nipple in between her teeth, causing Luna to quiver. Celestia finally takes her mouth off Luna's teats and looks up at her. Luna stares passionately at her big sister, her eyes gleaming with happiness and love.
Celestia looks down at her sister's teats before turning her attention even lower, to her sister's vulva. Celestia leans closely and sticks her tongue out, ready to begin pleasuring her sister. Luna waits eagerly as her sister's tongue slowly touches down on her vulva. Celestia slowly slides her tongue up and down Luna's vulva. Luna bites her lips as the pleasure begins building up inside her. It's been 1000 years since her sister has done this, and it was worth the wait. Celestia gets rougher with her tongue, pushing at a greater and greater force until…it pierces through, entering her sister's vagina. Luna's face goes blank as the pleasure overwhelms her. After so long, even this is a feeling so phenomenally amazing.
Celestia looks up at her sister as she digs in and out of her sister's vagina. A wave of pride and content washes over Celestia. She finally gets to see her sister's pleased face after so long. Luna can barely keep her eyes open as her sister keeps going, "C-Celestia…Celestia!" Luna moans.
Celestia shifts her tongue to Luna's clitoris, focusing her licks on that. Luna openly moans as her sister gently digs her tongue into her clitoris. Luna begins bucking her hips with the rhythm of Celestia's tongue. Luna quickly approaches climax as her wings flap open. Celestia continues to massage Luna's clitoris until finally, Luna moans loudly as she orgasms.
Luna lays there, catching her breath as Celestia crawls up to meet her gaze. Luna continues to struggle to keep her eyes open as she stares into Celestia's eyes. Celestia smiles passionately, having done her elder sisterly duty of pleasing her little sister. She lifts her head up to Luna's cheek and gently caresses it, "You never have to sleep alone again, sister. I'll always be here for you. Forever and always." She dives her face into her sister's, kissing her passionately like she was doing before.
Luna, just as she had before, pushes against her big sister in a rough manner. Celestia does not object, instead, pushing harder herself, giving into her own desperation for her sister's love. Celestia finally pulls away, ending the kiss with a stream of saliva connecting from the two sister's mouths. Celestia quickly lifts her hoof to cover her mouth, splitting the saliva trail, which falls onto her sister's cheek. "Oh! Sorry!" Celestia says with a smile as she leans forward and licks the stray stream of saliva off her sister. Celestia lifts her head back up and stares into her little sister's eyes.
Luna smiles and closes her eyes as her breathing finally begins to settle, "I love you, sister."
Celestia goes wide-eyed. Words she has not heard in years. Tears well up in her eyes. She leans in and gives Luna one final kiss. Once the kiss ends, she smiles with all the love in her heart, "I love you too, sister."
Luna slowly begins dozing off as Celestia steps to the side of Luna, giving her space. She lays her head on her sister's chest, tired herself, "Goodnight, Luna."
