HE GETS JEALOUS

LEO
After meeting the brothers you started to spend more time in the sewers. But along with that, you were also spending more time with the other brothers. Especially Donnie, being a nurse you and Donnie talked a lot about medicine and the human body.  

Today you walked into the lair waving at Raph and Mikey who were playing a video game of some sort. You spotted Leo in the dojo training so you let him be. Leo hates to be interrupted during training you say to yourself as you walk over to the lab.

"Donnie" you called out to the purple mask turtle. You found him with a blowtorch fixing or making something. He stopped "Oh hey Y/N, Leo busy" he asked "he is, he is training" you explain to Donnie. "Well, now that I have you for a few extra minutes can you do me a favor?" He asked.

Turns out the favor was just a simple check-up. Donnie says he wanted to understand the human body better.

By this time Leo wrapped up his training seeing what time it was. He started to wonder if you forgot about coming over. He walked into the living room with Raph and Mikey.

"Have you seen Y/N?" he asked looking at the both of them. Raph laughed at Leo as he said "Yeah she's in Donnie's lab" Mikey also spoke up "Keep up with her better next time man" as Leo walked away

Leo walked into the lab to see Y/N sitting on the table. Donnie holding a stethoscope to your chest. This sight made Leo uncomfortable and upset. Donatello's hands were huge so his hands were slightly touching your breast. Leo silently watched as Donnie began to speak to you. "I'm going to use it on your back now," he told you beginning to move and making Leo more comfortable with this.
Until Leo saw Donnie had to put his hand up the back of your shirt.

He couldn't do it any longer. "Donatello, what are you doing?" Leo meant to just ask but it came out harsh. Donnie must have picked up on it because he removed his hand and stepped away. You spoke up before Donnie did "Donnie was learning more about the human body." You explained as you got off the table to walk over to him. His eyes were still narrowed at his brother "Yes Y/N has been very knowledgeable in human anatomy" Donnie spoke looking at his notes.

Leo couldn't take much more so he told Donatello that you two were leaving and told him goodbye. As you tried to say goodbye Leo pulled you out the lab doors. By now you were getting upset with Leo. Leo was holding your hand walking- well more like pulling you into his room. You finally get there and Leo slams the door.

"Leonardo, what is wrong with you? Why are you being so harsh?" You questioned him as he stammered and turned a bright shade of red. It took him a few minutes to get the answer out. "I just didn't like his hands all over you like that" Leo confessed.

You had to admit you were surprised by Leo's reaction. You couldn't help but laugh a little bit. "Leonardo, Donatello, and I are just friends. He was just curious about humans is all" you explain to him as he looks guilty now. "Plus I love you very much so there is no need to be jealous" You cupped his face and kissed it.

As you pulled away Leo looked down at you "I love you, and I'm sorry" he sheepishly admitted. You gave him a hard look "Yes, but I am not the one you need to apologize to" you told him as Leo rolled his eyes "Fine, Fine" Leo threw his hands up as he walked off to the lab

DONNIE
You came to visit your boyfriend but he was too busy in the lab so you sat on the couch. You had to admit you were getting a little bored with yourself. Behind the couch, you heard Raph using the punching bag. You turned around and watched him strike the bag over and over.

After a few moments Raph noticed you watching so he stopped. He looked over at you "Wanna try?" He offered to you. You wanted to be close with all the brothers and you thought this was your only chance to do so. You got up and stood in front of the bag. "Yeah just hit in now" Raph encouraged you and you tried. It was just a little one and Raph let out a loud laugh. You felt a tad nervous and embarrassed.
