Work Text:

If you would’ve told Leo a few years ago that he would be the father of not just one but two clutches he wouldn’t have believed you. At the time Donnie was genetically male. After an unexpected result of one of his experiments going wrong, his genetic makeup changed to a female’s. A vital fact that was forgotten about when Donnie entered his first heat.

His first pregnancy was not only scary but exciting. Leo was sure to provide his mate with whatever he needed or desired. This was true even after Donnie laid said clutch. The only thing Leo would change was allowing Donnie to tinker away on projects for their eggs late within his pregnancy. Even though they discussed him going on bed rest all the softshell had to do was pout and say, “But our babies need this, Lee.” That was enough for the slider to back down. This second time, however, was going to be different. Leo was hellbent on making sure Donnie commits to his bed rest. They have everything their children could possibly need. Now, he just has to make sure Donnie has everything he needs.

“Donnie, baby, I’m back! Do you need anything?” Leo entered their shared train car to find an empty bed. After inspection it wasn’t even warm. “I swear if you’re in the lab…”

Leo swiftly made his way down to the lab passing by the living room and kitchen in the process. No sign of Donnie, great he’s definitely in the lab. Once through the lab door, Leo caught sight of his heavily pregnant mate underneath something he definitely shouldn’t be. As Leo approached, Donnie was reaching around for a specific tool unaware of the slider’s presence. “Shelldon! Can you grab me a ratchet? 3/8 please!”

Out of the corner of his eye, Leo saw Shelldon fetch the tool and make his way over. As soon as he saw Leo he froze, “Uhh Dee maybe we should take a pause of this? I wouldn’t want Leo to come in here and catch you breaking the bed rest rule.”

“Nonsense Shelldon I have time. Leo’s busy bathing the twins and getting them ready for bed. I just need to do this one thing then I’ll head back,” the cart supporting Donnie squeaked as it rolled out from under the contraption, “besides it’s only been 10 minutes he won’t even realize that I- Oh. Hello love.” His nervous smile grew little by little the longer Leo stared at him from above, arms crossed and everything. He means business.

 ---

“You really thought I wouldn’t know huh?” Leo set his mate down on the bed gently before fluffing the pillows behind him. The walk back was silent, Donnie didn’t know what to say. He felt like a scolded child, it didn’t help that Leo insisted on carrying him back to their room. “No… I was gone for less than 15 minutes. I didn’t think you could get the girls’ nightly routine done before I got back.” He refused to look in Leo’s direction when he was instructed to lean back, “I know I promised to follow your instructions on bed rest, but I got bored.”

The weight on the bed suddenly shifted, on instinct Donnie looked over to see Leo sitting on the edge of the bed beside him. Leo twisted his body for better access of Donnie’s hand, taking it into his, “Baby, I wasn’t gone that long. I came right back; we could’ve done anything you wanted- ah ah within reason. Don’t think I don’t see that look Don.” Leo chuckled seeing his mate puff out his cheeks. “Now’s the time for you to be super tired, demanding cuddles, and all the snacks your heart desires. We can’t have you falling asleep trying to build something for the kids, you and the eggs could get hurt. I need you all to be happy, healthy, and safe.” He placed a delicate kiss on the inside of his wrist, showing his love he wasn’t angered, just expressing concern.

A small churr escaped Donnie’s lips at the act. He loved when Leo did the little things. Whether it was acts of affection, providing for him or their children, or just being there. It meant a lot to him, proving he made an excellent choice in a mate and the father of his children when that opportunity presented itself. The thought alone stirred something deep inside him and he needed his mate to provide.

“Leo, love, I’m sorry. I haven’t been sleeping well lately so my cognitive functioning is not at where it should be. I should’ve been a good boy and stayed in bed but instead I disobeyed without thinking. Please forgive me.” Purred Donnie, running his fingers down the slider’s face before bringing them back up in a slow tapping rhythm. By now he could feel his tail leaking, hoping it would be filled momentarily. Seeing the sudden realization on Leo’s face made his tail wag, softly thumping the bed.

Donnie’s words made Leo want to reassure his mate, that was before the tapping and the smell of fresh slick came around. He knew his face was flushed; he could feel it. The sight of Donnie’s tail only made Leo lick his lips before taking it into his palm. Running his fingers over it earning him a small whimper. “Oh, don’t worry baby I forgive you. But what’s this about not being able to sleep, huh? Do I need to help you?”

“Mm… Nardo please” Donnie panted, wiggling his hips in hope that Leo would go further. “Please what? I need a proper answer.” He continued to lightly stroke his mate’s tail ignoring his frustrated huffs and moans. Finally, Donnie responded with words, “Please help me,” Leo started removing their shorts, unaware of where they landed within their room. Before he could even think about settling between those plush jade thighs his attention was pulled away, “Leo,” Donnie whispered reaching out for the slider to get closer, “Yes baby?” Their beaks now inches away from each other, “Fuck me till I’m gone.” He growled, pulling Leo into a bruising kiss.

Between tongues fighting and Donnie tapping away at his mate’s face, Leo was able to feel his way down to the soaking slit he was after. Inserting a finger ever so slowly, earning him a heavenly noise of a gasp mixed with a moan. Needing to hear more Leo kissed every square inch of Donnie’s neck adding a few licks and nips here and there. The steady rhythm of his single finger had Donnie panting, but two made him beg.

“L-leo, ah-AH, Leo please! I need more, g-give me more!” Donnie cried, gripping onto which ever part of the slider his hands found first. The feeling was enough to make him cry. It felt amazing, but it wasn’t enough, and Leo knew that. He wasn’t able to hit all the right spots needed for the ‘flood gates to open’ as his mate says. That’s exactly what he needs right now, just any second now.

He was wrong.

Seconds turned into agonizing minutes. He couldn’t take much more of his pleas being ignored, as a result he let out a single high-pitched whine. “Leonardo! Please! I need you, now! Right now, please!” The feeling of warm air sent a shiver down his spine, Leo chuckled, “Don’t worry Donnie, baby, you’re going to have me in just a second. I promise.”

Leo kept his promise, before Donnie knew it, he felt empty. It was terrible, his slit clenched around nothing. He needed to be filled again or he was going to go crazy. As he went to state yet another plea, he felt tingling heat slide up his wet folds. He looked down to see Leo’s whole length gliding up and down. Leo’s tip got caught a few times, causing it to graze his now swollen clit. At first it made Donnie squeak, eventually turning into panting. That feeling was building back up, he needed Leo inside him right this instant.

“Hang on Dee, I’m going to slip behind you.” The words did not process quick enough before he was being lifted and placed on Leo’s lap. “Wait, Nardo what? Why?”

The chuckles returned, “You’re going to love this, I swear. This position makes the most sense, you can’t be on your back for too long. So instead, you’re leaning back on me while I’ve got all these pillows for cushion. I could have been on top, but I don’t want to push too hard on your plastron. So, babe, if you don’t mind,” Donnie’s legs were lifted up and brought out, “Hold your thighs for me then I got the rest.”

Donnie didn’t need to be told twice. He watched as Leo brought his legs up closer, almost lifting himself up in the process. Before he knew it Leo was circling his clit slowly, unaware of the fact he was about to be speared open. When he finally felt Leo’s cock slip passed his folds, dragging against his insides, he let out the filthiest moan.

Leo was slow at first, testing the waters to see if the position would work like he stated. His trusts eventually grew faster, hitting Donnie’s buttons almost just right. Yes, his walls were pulsing, but he needed more yet again, “More Leon! Faster! Harder! Ah! Just b-breed me! Fill me again and again! I need all your eggs Leonardo!”

Everything abruptly stopped, a moment or two passed before Donnie thought he messed up somewhere. That was before he heard a low growl from behind. Was Leo angry at what he said? Should he apologize? He completely missed the hands being relocated to his ass, but he definitely felt teeth grazing his neck.

Without warning Leo bit down on Donnie’s neck, feeling as if he pierced through the jade scales. Letting out a pleasured cry, Donnie tried throwing his head back. It appeared as if Leo didn’t like the gesture, growling once more in response. Within seconds the trusts were back, this time in full force. Donnie’s pleas were answered taking every hard thrust gifted to him at a brutal pace. It was perfect! The feeling that was building before was there again, he was just waiting for…  His vision went white as blazing heat filled him up.

Leo removed himself from Donnie’s neck to cry out from his climax. The pressure he felt around his cock while Donnie was coming was just enough to tip him over the edge. He leaned back as much as he could to catch his breath. He looked down when he felt Donnie’s body start to twitch. He immediately felt terrible at the sight of the bite mark on his mate’s neck.

“Oh Donnie, babe, I’m sorry! I got carried away, my brain was saying ‘claim’, ‘ours’, and all that good stuff. I should’ve- Uh Donnie?” Upon further examination, Donnie was out like a light and was not going to be back anytime soon. Feeling a sudden dose of pride, Leo lifted the softshell up they were both going to need a bath. Then some new bedsheets…

---

After a nice bath, lotion, and a full body massage Donnie was finally tucked away under new sheets snoring away. Leo was a little surprised that the softshell didn’t stir once within the past hour and a half. He really needed this sleep. Feeling tired himself, Leo cuddled up to Donnie churring softly. As if on cue, small chirps erupted from the baby monitor Donnie made during his previous pregnancy. The sounds of their upset babies was the one thing to make Donnie start to grumble, his motherly instincts trying to take over and tell him to wake up. Leo quickly tried to muffle the device, lowering the volume. Looking back to Donnie, he could see that his mate looked peaceful purring into the body pillow he had supporting his baby bump. Leo smiled as he made his way to the nursery, he couldn’t wait to come back and cuddle him to sleep.
