Kaminari opened the door to see his boyfriend on the other side. "Toshi!" He lunged forward at him and held him in a hug.

"Hey Denks." He replied softly, holding him close. Kaminari pulled away and let him in his room. He walked in and shut the door. He was feeling a bit tired from his run in with a quirk earlier. The user had apologized but Shinso was already off before they could explain what it was.

Shinso went over to his boyfriend's bed and laid down. Kaminari crawled on top of him and laid down. He traced shapes on his chest and smiled softly. Shinso chuckled and ran a hand along his back as he closed his eyes. He fell asleep not long after. Kaminari snuggled closer and soon followed.

After a few hours Shinso woke up, feeling strange. He rubbed his eyes and yawned before looking down at Kaminari with a soft smile.

The blond was clinging to him in his sleep, while he snored softly. He chuckled and ran a hand through his hair gently. Kaminari shifted a little but stayed asleep.

Shinso carefully got out of Kaminari's vice like grip and got up to stretch. He yawned again and felt something poke his lip. He brought a finger to his mouth and touched it lightly.

He frowned slightly and went to the bathroom. To look in the mirror. His mouth dropped open when he saw his reflection. He had two black ears and a tail.

He opened his mouth to look at his tiny fangs. He freaked out and his tail puffed up slightly. "Toshi." Denki said softly as he looked up from the bed. "Where did you go?"

His ears twitched, hearing him.
"I'm in the bathroom, kitten." He replied as he touched his ears, curiously. Denki got up and went to the bathroom. He gasped softly when he saw Shinso.

"Omg so adorable!" He cooed as he  went over to him to pet his ears. Shinso blushed and his ears twitched.

"Baby!" He whined. His tail swayed through the air liking the attention.

"Oh hush you like it." Kaminari cooed as he held his face in his hands.

He pecked his lips lightly and giggled. Shinso had closed his eyes and was purring softly from the attention.

"I wonder how this happened." Kaminari said softly as he stopped and looked down at shinso's tail.

"I have a feeling it might have been the person I ran into earlier." He mumbled as he let denki grab his swaying tail. The feeling warmed him and he couldn't help but purr louder. Kaminari smiled and stroked it gently.

"So fluffy." He mumbled softly.

Shinso laughed softly and pulled him close. "We should probably go see Recovery Girl and get an estimate on how long this should last." He said softly.

Kaminari nodded and let go of him. Shinso smiled and fixed his hair before walking out into the bedroom. Kaminari followed and grabbed his phone.

They left for recovery girls office.

~timeskip hour~

The both of them were walking out of her office. Kaminari was holding Shinso's hand and Shinsos tail was wrapped around the boys thigh.

Kaminari blushed lightly and looked up at him. "You wanna go get something to eat?" He asked softly.

"I was just about to ask the same thing." Shinso laughed softly and pulled him closer. Kaminari pecked his lips and dragged him to the kitchen.

"I can't believe this will last a month." Shinso said softly as they made something for dinner. "Yeah well we should make the most of it." Kaminari said with a grin.

Shinso blushed when he thought about what Recovery Girl said about his sexual drive. Since he'd have the instincts of an animal he'd want to breed.

His tail swayed and he shook his head. 'I can't do that to Kaminari.' He thought. They hadn't gone past kissing or cuddling and he knew Kaminari wasn't ready. He glanced at the blond who was doing his best to follow his boyfriends instructions as he cooked. Kaminari looked up and have him a small smile.

"What's on your mind?" He asked softly

"Uh.. . Drugs?" He said unsure.

Kaminari laughed and hit his shoulder lightly. . "Liar."

Shinso gave him a smile and leaned down to peck his cheek. "I'm just thinking about this whole cat thing." He replied softly.

Kaminari nodded and went back to cooking. He held a spoon up to his lips and shisno took it in his mouth. "Tastes awesome." He murmured. Kaminari smiled and started plating the food.

"Hey Denks.' Shinso mumbled after a moment.

"Yeah Toshi?" He replied as he handed him a plate.

"Would you maybe want to. . ." He trailed off and a fang dug into his lip as he began regretting bringing it up without thinking about it more.

Denki looked at him curiously.."what is it toshi?" He asked softly as he set a plate down for him and himself.

"Nothing. . Nevermind." He said with a smile. "You did a great job. " He added trying to change the subject. Kaminari had a feeling he was keeping something from him but nodded as he sat down and began eating. Shinso did the same and occasionally glanced at him. His tail, with a mind of its own slithered into the blonds lap and rubbed against his thigh.

Kaminari's face turned a bright pink and he looked down at the plate of food intently not wanting shinso to notice how much it affected him. Shinso could smell the arousal easily and he perked up.

Kaminari stiffened. (His body. Ya nasty) it was quiet for a few more moments until their friends entered the room. Mina's eyes lit up when she saw kitty shinso and she was immediately by his side patting his head gently. "Aawwwww soon cute!" She cooed. Shinsos ears twitched as she scratched them.

"R-right there." He murmured as his eyes rolled back. Kaminari blushed brightly and got jealous. He pulled shinso away from Mina.

"Let's go back to our room." He said softly to him feeling sexually frustrated. Shinso could smell it on him and nodded, still in a daze from his ear scratches.
