“I’m not kidding, Timbo. This is a side of me that’s not fun to fuck.”

“Lucky for you, I think every single part of you is fun to fuck~”

Jason rolled his eyes - he honestly didn’t know what Tim saw in him. Jason’s rebirth in the Lazarus Pit was at the cost of part of his humanity. When he came back, he was able to turn part or all of his body into a shadowy, tentacled monster with red eyes. Jason wasn’t kind when he was in this form - he drained the life from his enemies by constricting them with his tentacles, to the point where some couldn’t breathe. It made the Red Hood a terrifying figure in the Gotham Underground, as many stories about Jason’s inhuman form were true. 

Most of the Batfamily and his allies had become very cautious about confronting Jason - they knew his short temper and inhuman abilities could lead to nasty injuries if they upset him.

Tim was the only exception. From the very beginning, he had been entranced by Jason’s ability to change shape. Once, when Jason had fully transformed, while everyone else ran away or backed up cautiously, Tim approached Jason and stroked his cheek. When Jason wrapped his tentacles around Tim as a warning, Tim simply stroked them with fondness. They moved quickly after that, dating and becoming extremely close. Jason used the tentacles during their intimacy sometimes, and Tim never complained - in fact, Tim enjoyed when Jason’s tentacles came out and stroked and felt him during sex. 

This was different though. Jason had only gone through a few breeding cycles in his eldritch form before - they were feral and intense, as his body wanted to grab and breed whatever he could. His eldritch form would also create and release eggs, as it desperately tried to continue its bloodline. Jason always disposed of the eggs, never seeing them as something sexual.

Tim, however, loved the idea of being pumped full of the eggs. Now lying in front of Jason, completely naked as Jason was about to go feral. The scent of sex enticed Jason’s body, and it desperately wanted to let go and fill Tim’s cunt with as many eggs as it could.

Tim teased, “Well~ do you want to fill my cunt? Or do you want to fill my ass?”

Jason growled, almost ready to let go, “Your cunt. Let me breed you. Let me fill you. Then let me watch you give birth to my eggs.”

Tim almost moaned at the order, saying, “Yes…let go, Jay. Let your body have me.” 

Jason didn’t hesitate - he flipped Tim onto his stomach and pulled his hips upward, framing his wet pussy and asshole. Tim had already prepared himself, expecting a normal night of fun before Jason had told him about the situation with his breeding. Jason thumbed Tim’s perky clit a few times before lining up with his dripping cunt and draping his body over Tim’s back.

Jason spoke breathlessly, “Tell me you want this. Tell me you need this.”

Tim groaned from under Jason, saying, “Please, Jason. Fuck me. Fuck me deep. Breed me.”

Jason almost howled as his body shifted forms. His skin was covered in a shadowy black substance, his eyes glowed a bright red, his hands became taloned, and from his body emerged dozens of independently controllable tentacles. Jason didn’t hesitate to plunge his enveloped cock into Tim’s dripping cunt. 

Tim groaned, “Yes…! Jason, more!”

Jason growled and began fucking Tim hard and deep, trying to ensure he got deep into the smaller man’s warm, wet cunt. He scratched down Tim’s arms and back gently, holding back from digging to deep. The tentacles all moved to grip around Tim’s body, holding him in pace so that he wouldn’t try to move or get away. They let out a gooey, lube-like substance onto Tim’s skin, which he had grown used to over time.

The sound of wet sex filled their bedroom. Jason groaned animalistically as he tried to get deeper in Tim’s needy hole - he wanted the eggs he was going to release to be secure. It wasn't long before Jason’s cock swelled and hardened. 

Tim begged, “Please! Jason! Fill me!” Jason growled deeply and began releasing the first egg into Tim’s body. It was slow at first, with Jason’s cock getting thicker and harder before slowly depositing the first egg. After the first one, Jason roared and held Tim in place as he began filling him with more eggs. Each egg made Tim’s stomach feel so full, feeling like he was going to burst.

After about 7 eggs, Tim began to whine - the pleasure was still there, but he swore his stomach was going to pop. Jason continued to leave marks and goo on his skin as he lay a few more eggs inside of Tim before quickly pulling out of Tim’s overstuffed cunt.

Tim yelped as Jason manhandled him onto his back. Jason began to slowly change back into his human form. Once he was back, he started stroking Tim’s clit, causing the smaller man to howl in pleasure.

Jason ordered Tim, “Let them out, Timbo. If you don’t, they’ll latch on to your insides and start growing into more eldritch beasts. I want to have kids with you someday, but not like this.”

Over the next half hour, Jason slowly helped Tim push out the eggs one by one. It was weirdly erotic to watch Tim birth the eggs one by one. After Tim was done pushing them out, there were 10 eggs on the bed. 

Jason sighed, saying, “This is why I didn’t want you to be with me during my breeding cycle, Timbo…”

Tim spoke up, “I felt like my insides were going to tear…but it felt fucking amazing, Jay. I could feel every single one of the eggs settling inside of me, and it felt heavenly. Please…please let me be with you during your future heat cycles too.”

Jason smiled, hugging Tim and telling him, “You’re ridiculous. I love you.”

Tim smiled and said, “I love you too. Every last part and version of you.”
