Suicide Attempt

The first time happened while they were just friends.

He was working late, as he did frequently. Tony had built that lab especially for him, displacing an entire department to open space. Of course, Bruce did everything to not accept the gift, even said that he would soon leave. But as Tony built it in secret and took only two days to get everything ready, there wasn't much he could do. Secretly, he was glad to have a place where he could fit in so well.

Everything was perfect, but he should have suspected that nothing good in his life lasts long.

He was about to retire to his room when he saw Tony lying on the ground. He ran to help, struggling to hold the Other Guy, looking for any source of danger. But it was clear that there was no enemy, he could smell the whiskey for several meters. Tony had just drank until he passed out.

"Tony, are you okay?" he asked without expecting an answer.

"Brucy!" Tony yelled looking at him, though it is obvious that his eyes were out of focus.

"Come, I'll take you to bed." he said lifting the other man's body, which wasn't so easy with Tony throwing himself on the floor.

"Not that I have anything against it, but I usually demand a dinner before." he said, extremely coherent for someone in his state.

Bruce blushed lightly, and was about to answer when Tony pulled him into an awkward kiss tasting like vomit. He pulled away instantly, taking care not to drop Tony.

"You are going to your bed to sleep. Alone."

Unable to lift his head to kiss him again, because the world was spinning too much, Tony began to move his hands between Bruce's legs and then grabbed his crotch over his jeans. The shock was so great that Bruce dropped him on the floor.

"Wouldn't you rather go to my room? I have a bed there. Not that I have anything against the floor..."

Bruce rolled his eyes.

"If you don't behave, I'll let you sleep on the floor."

After that, he lifted him again, and managed to carry him to his room almost unmolested. He tossed him on the bed without much care, but turned his head to ensure that he wouldn't drown in his own vomit.
