Tony's panic attacks

Tony's experiment

"Bruce?" Tony ask.

"yeah?" Bruce ask.

"I need some DNA." Tony said.

"why?" Bruce ask, looking up at him.

"well, I'm doing some tests on myself and I figured I could do it on you too, it's nothing dangerous and doesn't have anything to do the Hulk. just a few little things." Tony said.

"blood or cheek swab?" Bruce ask.

"well see... thats not the DNA I need." Tony replied. Bruce's cheeks lit up.

"why the hell do you need that?! " Bruce ask.

"I told you. science." Tony replied. Bruce stared him down.

"fine." Bruce muttered getting up.

*a few weeks later*

Tony was nervously avoiding everyone, including Bruce. until Bruce cornered him.

"okay Tony, whats wrong with you?" Bruce ask. Tony gave a nervous laugh.

"well, I'm told I don't play well with others...." Tony replied.

"no, whats wrong with you lately?" Bruce ask, crossing his arms over his chest.

"well... you remember that experiment I did?" Tony ask. Bruce narrowed his eye's.

"what the hell did you fucking do?" Bruce glared. "did you fuck something up?" Bruce ask. Tony hesitated and shook his head.

"no never mind. nothing happened. I just got the worst results in the world. the test didn't work. I just didn't like that it didn't work." Tony muttered turning around. he didn't like lying to Bruce, but Bruce wasn't going to like the answers Tony had gotten. Bruce frowned.

"Tony you're being defensive. whats wrong?" Bruce ask.

"nothing it's fine. just go be angry somewhere else. I have things I need to do." Tony glared, motioning to Natasha who was waiting in the lab for him. Bruce sighed and nodded leaving. Tony walked back over to Natasha.

"so what was it you wanted to talk to me about?" Natasha ask.

"I did some tests and things, you know about how we talked about me helping you get pregnant." Tony said. she perked up.

"yeah? and? can you do it? me and Clint really want a kid. wait how'd you test it?" Natasha ask.

"well I had to find someone else who couldn't get pregnant, but I couldn't find a volunteer." Tony said. Natasha sighed and her shoulders drooped.

"I see." Natasha muttered moving to get up. "so thats a no." Natasha added.

"no, I said I couldn't find a volunteer." Tony replied. Natasha looked at him confused.

"so what? you ran a test through Jarvis and it worked?" Natasha ask.

"no." Tony sighed. she looked confused at him and he bit his lip. "I, uh, used myself." Tony said. Natasha's jaw dropped.

"you what?" Natasha ask.

"I used myself as a lab right. I figured if I could get someone who it was physically impossible for it to happen to, then I could make it work with you. well, it was physically impossible for me, so I used myself and I haven't told Bruce." Tony said, waiving it off like it was nothing.

"you... really tested on yourself for me?" Natasha ask. Tony nodded. "and you got yourself pregnant without telling your fiancé?" Natasha ask. Tony nodded again and she hugged him tightly. "Tony you're an idiot! thank you!" Natasha exclaimed. Tony pushed back.
