(M rating, yadda yadda yadda. Small bit at the end isn't.)
Tyrath then pulled Luna into a deep kiss, pulling her close to him as he embraced her.
"I think I owe you something." He breathed close to her and she shuddered in response, his warm breath hitting her.
"Oh indeed you do." She nodded. Suddenly, she teleported them into her bedroom. She wouldn't wait any longer. She wanted to make everything up to Tyrath, "It is my turn now sister." Smirked Luna, glancing at her sister who was watching closely.
"Very well." She smiled and sauntered away, but Ty's attention was focused on Luna, although, he also relished in seeing Celestia in his peripheral view. Both these mares were beautiful, incredible, sexy and just amazing. And all his. He pulled her even closer and kissed her again, both their tongues wrestling for dominance. He pushed her against the wall and she gasped, wrapping her hind legs around his waist, clinging to him as they kissed tenderly. She loved being handled rough like this, like a mare. Tyrath placed a hand on her cheek and regarded her for a second. His Dragon Instincts begged him to have her, to take her. To make her his forever. To mate her. He took heavy breaths to calm himself, to give this perfect mare the night of her life. He began to lose himself to her, his instincts beginning to show themselves.
"Luna... You're so beautiful." he looked into her eyes as he spoke. She averted his gaze with a blush, but he raised her head so she looked him in the eye. "You are. Inside and out." he spoke from the heart. Luna could tell, her heart couldn't take it, it was beating so incredibly fast, filling her with even more love for him.
Luna threw herself at him, using her wings. He was forced backwards, gasping in surprise for a second as Luna lay kisses all over him as he fell backwards onto the bed. She looked at him with tears in her eyes.
"Thank you, Tyrath. That is the kindest thing anypony other than my sister has ever said to me." she choked on a sob, wrapping herself around him tightly, refusing to let go as she gripped him tight. Tyrath chuckled quietly at how strong she was. She and her sister were both strong mares, and he found that attractive. He growled lightly, wanting her even more.
She heard his growl and knew he was enjoying her already, and she grinned. She looked up at him and kissed him deeply, and he returned the kiss with just as much vigour. The feeling of their bodies pressing together made them both shiver in delight.
"Yes, Luna..." he breathed. She flared her wings and his breath hitched. She smiled, knowing the effect she had on him.
"You're going to rut me like a mare tonight, Tyrath." she told him and quickly undressed Tyrath, taking his cuirass off and then his greaves, his gauntlets and boots coming off along the way. Luna looked at Tyrath hungrily and he began to take her regalia off, lifting off her chest piece and then the crown as she stepped out of her shoes.
He looked at her, finding her so sexy without anything on. He breathed heavily, barely containing himself. Luna herself was blushing heavily as they regarded each other. They then launched themselves at each other, making out furiously, wanting each other so desperately.
"Oh yes, make out with my little sister..." moaned Celestia as she got herself off watching them both. Tyrath used magic and pulled Celestia toward the bed. She squeaked in surprise as he kissed her, leading her to moan louder and she pushed her hips into her hoof. Then, Luna pushed Tyrath on the bed and blushed as she watched him below, watching her with unending lust and love.
"Can I... Be on top?" she asked nervously. She was nervous? Now?! She smiled at him, gripping his waist tightly with her hind legs, leading him to groan in pleasure and he ran his hands along the waist of this beautiful mare. His beautiful mare. He smiled lovingly at her. He wanted so bad to just lift her up and drop her onto him, spearing that lovely body with his length. But he held back. It was all about her, and her pleasure.
"Of course, my love." he said to her, sitting up and kissing her where her chest would be if she were human. But she wasn't. She was a Pony. His Pony. He wanted her as she was. She was perfect how she was. Human females be damned. Nothing compared to these two mares. He pushed her backwards as he kissed, he wanted more than just being inside her, though. Despite what everything within him was screaming for.
"But first, I want to taste you again." he breathed and her breath hitched along with it as she squirmed, needing release. He smiled as he kissed downwards and sucked her teats. So good. He licked all around them and lightly bit her nipples, causing her to gasp and writhe in his grasp.
"Oh yes... Yes Tyrath..." Luna moaned loudly, causing her sister to gasp and moan loud as well, wishing that was her. But tonight was for her sister. And she enjoyed seeing Luna writhe in their lovers grasp. She remembered the teasing, and how it was oh so worth it.
"So good. Your teats are so lovely." he smiled as he kissed them a few more times, working his way down until he was before her marehood. He inhaled her scent, as he had with Celestia. It was amazing and it drove him crazy. It was her own scent, unique and amazing, like her. Like It made him want to just take her, to push inside her. But he resisted that urge. This mare's first time was going to be perfect. He licked her once and he watched her wings shoot out uncontrollably, and it spurred him on. He licked faster, and pushed his tongue in her, causing her hips to push up, wanting more. And he was happy to give more to her. He sucked on her clit as it came out and Luna gasped and strained out another, cumming into Tyrath's mouth as he latched his mouth over her. He wanted all of her. To drink her.
"Yes, drink Luna's cum... All of it... Yesssss..." Celestia moaned loudly as she came hard as well. Tyrath slipped a hand down beside the bed between Celestia's hindlegs and caught as much of her juices as he could. He brought his hand up and licked it clean and both sisters moaned, wanting more instantly. Tyrath flipped over with Luna so she was straddling him.
"I'm all yours, my sexy Princess." he told her, looking at her with loving eyes. They held a desire, a craving, for just these two sisters. Luna saw it and it made her even hotter, knowing he was all theirs. Forever. She raised herself up and positioned herself over him, her juices dripping onto him. He felt her heat and he desperately wanted to thrust up into her, but he wanted her to set the pace. He was all hers tonight.
"Did you know, Tyrath, that my sister and I are incredibly fertile?" she said and saw his eyes turn yellow and begin to narrow as his breath stopped for a second. "But only to other Alicorns, such as yourself, human or no. Eventually, we will enter heat. You know what that means, my love?" she asked, leaning down next to his ear. "You can sire me a foal." she breathed heavily. Tyrath was sweating. Fuck... this mare... She knew just what to say. How to drive him crazy, make him lose control...
"Yes Tyrath... Our marehoods will be so sensitive, so hot and they'll hurt. We'll need you to make it better. Only you." Celestia said, getting on the bed and spreading her legs for him, exposing herself. Fuck, they got even hotter? Just the thought made him even more aroused.
"To make it better, we need you to let yourself go inside our fertile bodies. Will you do that? Will you breed us when we're able to have your foals? Still cum inside us?" she asked. She then lowered herself slowly onto him, gasping as he filled her up perfectly. She stopped as he came across her innocence, brushing against it. "Do it, my love. Take me." she begged. Tyrath thrust up and pulled her down, entering her fully. She cried out in pleasured pain.
Tyrath stopped for a second, letting her adjust. Ignoring the burning desire to push her up and drop her back down onto him. Her heat was incredible, and he needed to stay in control to not cum right there. Luna then lifted herself and began bouncing slowly on top of him. Tyrath met her with light thrusts, unable to control himself. She got faster as he felt another warm feeling, but this was... Different. Yet the same. It was unique to Luna, he felt them connect, their emotions as one, their minds and bodies. They were meant for each other... Always. He felt her pussy grip him just right. He was keeping himself in check, but it was so hard...
Their inner magic began to open up to one another. As it did, and they felt each other for the first time, seeing the other in a new light, Tyrath saw Luna smile brightly as they connected, the both of them so happy that they'd found the ones they needed to be with forever.
"Yes, fuck, Luna... You feel amazing... I'd still do it. I'd cum. I'd get you both pregnant. Gods, I would." he cried out as they slammed against each other, with Luna moaning out as well. He needed this mare, both these sisters... All the heartache from before was forgotten as they knew in that moment they were meant for each other...
"Oh, yes!! We'd want you to! When you're inside, always cum there! Please, I want to feel your warm cum fill me. I want to know how it'll feel as you impregnate me." she smiled, Tyrath went crazy and slammed into her as hard as he could. He felt the bed crack and splinter beneath them as he thrust inside this mare while she bounced atop him... "Make me a mother, Tyrath. To our foal. Please." she begged him. He groaned and moaned beneath her. She took his hand in her magic and placed his hand on her stomach. It drove him even more crazy... "Feel it Tyrath, feel where your foal will grow." she whispered to him and he kissed her passionately.
"Yes Luna, yes... Have our babies... Have them... Gods yes... you'll be such a good mother..." he panted and she smiled and blushed. "Luna, have my foals..." he pleaded to her, beginning to wish he really could do it right now...
"Yes! I want your foal growing inside me tonight!" she called out, wishing the same thing as they made love. Their eyes looking into the others with nothing but love and lust in them. Both in their purest forms.
"Oh YES, give my little sister your foal! Knock her up! Do it!" screamed Celestia as she kept on pleasuring herself, wishing that it was her on top again... Wishing it was her he was saying these things to. In way, it was. It was both of them. And that thought made her even hotter.
"LUNA, OH FUCK YES LUNA, I'M CUMMING FOR YOU!!! YESSSSSS!!!" He yelled as he couldn't hold back anymore. He thrust inside her quickly a few times and held her down on top of him as he emptied inside her, feeling their connection deepen immeasurably as their inner magic collided.
"YES... OH YES... SIRE US A FOAL!!! GIVE US YOUR BABY!!!" she screamed out as she came with him and they both had a violent magic outburst, with the magic of both of them shaking the castle to the roots. Luna's eyes went white and Tyrath's went yellow and Draconic as he roared in pleasure like a Dragon, letting all know that this mare was his now. He emptied into his Princess and her juices dripped down his cock. Luna collapsed atop him, laying her head on his chest and he smiled as she looked up at him.
(Safety zone, sort of. Some mature themes, none of the explicitly sexual variant.)
"Fuck, that was amazing." breathed Tyrath, holding Luna close.
"We... I may have gotten carried away." Luna said sheepishly, hiding behind her hooves with a heavy blush, as if ashamed.
"Don't worry, Luna. It was so hot." he said to her, gently pulling her hooves away so he could see his Princess. "And I meant what I said." he smiled at her, placing a hand on her cheek and she wrapped herself around him tightly.
"You... You did?" she asked in surprise and Tyrath nodded to her "I'm so glad. The thought of me carrying your foal..." she placed a hand on her stomach and looked at him. "It felt so good... So right." she admitted, looking him in the eyes. Tyrath never thought he'd even dream of having children with anyone, let alone with two Pony Princess sisters. But these two captured his heart completely and he found himself wanting so much with these sisters. Hell, if not children, he definitely never would've even conceived of the notion that he would have foals. But lately he had been seeing these two as mother figures to their little Ponies, and found himself thinking of them as mothers... It was instinct he couldn't help.
"It did." admitted Tyrath, looking at his Princess in the eyes, showing he meant it.
"You called me mother material, remember?" she sighed as she remembered the dreamscape of Scootaloo. It was true, he thought right then she'd be a great mother, and he had told her as much.
"I meant it." he also sighed in happiness. Celestia snuggled close to his side as she climbed on the bed as well and he kissed her. "So would you, Cel. I've seen how you are with Twilight and your subjects. You'd be a great mother as well." he smiled and she snuggled closer to him, 'hmmm' ing in appreciation, too tired to speak. They all drifted off together...
