Celestia pat a large cushion softly with a hoof. "Lay down here and roll over for me. It is time to be examined."

Twilight shivered softly. Celestia was speaking in that commanding tone that thrilled her, for good and ill. She felt like a young thing again and scrambled to please her mentor. Being on her back was a little harder with her new wings, but spreading them out gave her a wider base the rest on and made her stable. She looked up at Celestia curiously, tail twitching in little jerks. "I am ready to--"

Celestia set a hoof on Twilight's snout, silencing her. "It is your turn." She could hold being worshipped a moment. She wanted to lavish Twilight. Leaning in, she started at the snout. Her breath washed over Twilight, making the fur dance as she came closer and closer. A soft nip at her once-pupil's throat had Twilight tense, but that faded as she ran her soft tongue over the same place. A gentle nuzzle marked her slow descent towards the main event.

She did not need her snout there to reach there, however. As she groomed and preened at Twilight, her horn glimmered faintly. Her will reached down and tickled over Twilight's unused teats, brushing against the sensitive flesh to stimulate them in slow circular rubbings that had them growing firm and flush with rushing blood. Her precious Twilight had never experienced foaling, so they would not be very large, but they were still an intimate place, where only those very trusted were permitted. Being allowed to rub and fondle them, and to hear the excited breathing it caused, was a heady elixir for Celestia.

Her snout ran across Twilight's ribs, feeling each bone in turn and kissing them. She was not in a hurry. It was a fine time to simply worship the miracle that was her beloved once-student. "Twilight, you are not told often enough, but you are a good pony. Even at your lowest points, you are trying to do well." She kissed just above Twilight's heart. "I have always admired that. Unflinching, you try to face the sun at all times."

Twilight reached out with her hooves, cupping Celestia's face. "Who would not want to face you, Celestia?" She was smiling coyle, squirming under the exploring intimacy of her larger peer. "You have always been my role model, who I try so hard to be like."

Celestia nuzzled gently into the frog of each of Twilight's hooves, burying her face into their palm and kissing each. "You will never be me, nor should you be. You are Twilight Sparkle, and that is a wondrous thing to be." She ran her face down Twilight's left foreleg, kissing her way along. "Loyal and treasured friend, who would help me at a moment's notice." She perked her ears at Twilight. "Why I hear she's even willing to help the princess foal, how generous of a mare to do."

With a soft chuckle, she lowered past Twilight's hooves, only to suddenly freeze. Twilight had not stayed still as asked. Her long horn, indicative of her intense magic, had been caught in the lips of the new princess. Twilight softly suckled at the tip as her hooves held it in place. The horn was not the most sensitive place to gentle attention, but it was such an important place to any unicorn, the idea of someone kissing, or in this case sucking on, it could bring powerful emotions that made it feel sensitive. It was a precious thing, and required trust to enjoy having someone touching it.

Twilight sank herself down on the mighty lance, braving its sharp point deep within her snout as her tongue bathed over it. She pulled gently like a timid child, watching as it made the large form of her mentor squirm. Celestia's horn had a faint taste to it, the barest hint of something sweet that Twilight enjoyed, though she doubted there was any part of Celestia that would displease her.

Celestia drew back, bringing her horn clear of Twilight's suckles. "Mmm, naughty mare. I said it was your turn."

Twilight pointed up at her. "You also said you wanted a peer, not a student, and your horn was too tempting. Nopony else has one quite so... perfect."

A gentle blush warmed Celestia's cheeks. "It is large, but that is not a singular mark of perfection."

"You're too modest." Twilight sat up onto her haunches. "Your horn is a reflection of your inner power, your mastery. It shines with your majesty and grows with that same amazingness." Her own cheeks darkened to match Celestia's. "I was... surprised when mine enjoyed a growth spurt after becoming a princess, but that was... logical, reaching a new level of understanding, even if I barely comprehended it at the time." She stood up, tail wagging like an eager dog. "I love your horn. Not that I don't love the rest of you, because I do!"

Celestia could feel Twilight starting to stammer and silenced her with a sudden kiss. Their lips pressed together and eyes closed. There was no awkwardness in that precious moment, just two mares exchanging empathy and love.

Troubleshoes rose to his hooves. "Pardon, ma'ams? I'm feeling better now." His heavily fortified jewels had replenished themselves, and watching them be ever so lovingly intimate was doing wonders for his libido. He wanted to join them.

Celestia glanced towards him with a new thought forming. "Very well." She spread her hind legs a little in obvious invitation, her voluminous tail sweeping aside. "Come. I will be doing something with Twilight as you work, my precious stud."

Twilight's ears went up and rigid. "You don't have to! Enjoy yourself, really."

"I insist." Celestia kissed her nose, then raised a forehoof, twirling it. "Around."

Twilight turned away from Celestia, blushing fiercely. Troubleshoes came up behind Celestia and leaned in, nuzzling at her weeping lips instead of just mounting her. His tongue was just the right combination of rough and soft that made her tremble with pleasure. She wanted to be mounted, but she would not decline a little attention from the male beforehand. Her rump raised as her forebody lowered a little, presenting herself fully to his questing mouth.

"Dear Twilight, since you like my horn so dearly..." Her alicorn shone with her magic, reconfiguring in shape just faintly. She would not dare do what she intended with the mighty spear she normally had and tapered it to a smooth end. "You will have it, all that you can stand." She kissed the back end of the purple princess and was rewarded with a sudden wink of arousal from those lips. Twilight was ready, she was sure of it.

Troubeshoes tried to peek at what was going on, but seeing past Celestia's heavenly rump while his face was busy tending to her proved an impossible task. He could only listen as they played. He was a little jealous of their clearly intense bond. He dared to hope that, as Celestia's stud, he would earn some small echo of that connection. He captured Celestia's clit as it winked, holding it in his powerful lips and suckling on it ever-so-gently.

Celestia shivered with mounting pleasure. Her new stud was doing well at pleasing her. She lowered her head and drew Twilight back with her magic, pressing the smoothed end of her horn against Twilight's entrance. She teased in a slow circle, rubbing her horn in a tracing of those sensitive lips. "Are you ready?"

Twilight was biting her bottom lip. She hadn't imagined that what Celestia was about to do would ever really happen to her. "Y-yes!" Her cheeks was burning bright at the thought of it. What if Celestia worked some strange forbidden magic and meant to breed her with her horn? What if she got too excited and they hurt her perfect horn? What if somepony walked in?! She was breathing hard as possible calamities played through her overeager anxiety.

Celestia sank several inches in, wetly parting Twilight's slick passage. She could feel the griping length of Twilight's tunnel rippling along her horn and began to seek out the more sensitive portions of those trembling walls. Every squeak and flex of the smaller princess was a victory. With her magic running through the horn powerfully, its sensitivity was higher than normal. She reshaped herself as she plunged, matching her invasive weapon to match the sheath that Twilight provided, to complete her so perfectly that Twilight began to feel like a part of her horn, especially when Celestia slammed fully in and Twilight rest fully on her forehead.

Troubleshoes could stand it no longer. The wet sounds of Twilight being rutted were driving him wild with his own lust. He had to have Celestia. He reared up and hugged her from behind as he stepped in, plunging his aching tool into the hot tightness it was meant to be in. He had a foal to make and he meant to do that. With a powerful thrust, he drove his flat-ended shaft deep into the shapely contours of his princess. She was hot all around him, even warmer than the first time, and he loved it. He loved her. He wanted nothing more than to be her stud, topping her whenever she got that special itch and driving it from her the way only a stallion could.

Celestia was trapped between lovers. When she drove forward, she drew a soft yelp from Twilight, her body trembling in pleasure. When she leaned back, she was speared by Troubleshoe's mighty tool. Each stroke was one of building bliss for her, and she rocked back and forth, trying to maximize both. She felt something coming, a tension that built all through her form. Was it an orgasm? It didn't feel quite right, but it did feel good, and she moved faster, racing for whatever it was that was coming.

She could feel her passage growing tighter even as Twilight's mirrored it. She nudged her horn just a little larger, giving herself a flare at the end just as she felt Troubleshoes swelling within her tight confines, ready to unleash a fresh wave of life into her. She suddenly raised her head and Twilight screamed with alien pleasure as she was lifted clear from the ground, impaled on her and caught. Every little squirm she made drove Celestia's horn-shaft against her sensitive walls.

Troubleshoes gave a deep whicker as he reached his peak. He could feel the tremendous amount of seed bursting forward, forced up through his shaft in powerful twitches of the tool, aided by overwhelming milking ripples of the mare he was in. He began painting her insides with his seed as he trembled and held to her as tightly as he could. In that moment, they were one, and he knew only happiness.

Celestia felt that spreading heat and everything went white as she spilled over the edge only to find that it was not a single one. Her horn glowed brightly enough to be visible through Twilight's belly as she climaxed through it in a uniquely unicorn way. Immense waves of magic rushed free and unfettered through her spire, emanating in all directions into Twilight's flesh while most of it fired up into her womb. Twilight lowered her hooves to her lower belly, her moan becoming more of a strangled gasp as sensations she had never felt before rocked her very core. She was being flooded with Celestia's magic in a way she never had before and it topped any other climax she had ever experienced.

Twilight let out her breath in a ragged sigh as the magic began to ebb. "What... was that?" She asked as she looked over her shoulder to see Celestia with her eyes tight shut. "Celestia?"

Celestia suddenly sank, her legs giving out. Twilight and Troubleshoes crashed into one another as the powerless mare between them collapsed, leaving them in an abrupt pile on the floor.
