It was his favorite place in the whole wide world.
He didn't really care where he was as long as he was next to Tim, preferably at touching distance. A little touch always convinced him that Tim was still real and that it wasn't all the best dream he had ever had.
His touches marked Tim. Every touch screamed 'mine!' He wanted everyone to know that Tim was his and he hated it when Tim flirted with other people, or other people with Tim. He always felt the need to push other people away, and touch Tim, holding hands if it was possible. Tim had told him to get over it, but he didn't want to.
He could handle Abby, and he was glad for that, because Abby liked touching people almost as much as he did. More specific, she liked touching Tim as much as he did.
Tim rarely touched him back. He wasn't really a toucher, he liked things clean and he wasn't always sure if something was clean, so he preferred not touching it if he had the change. But sometimes he touched Tony at work, to feel his warm skin, or to reassure him. It made Tony's day. His skin would feel like it was burning and he took really good care that nothing else touched that particular spot.
One day Tony had told him about it and Tim had snorted. Waving it away with his hand, but the next day, he had made it a point to touch Tony as much as he could. Be the end of the day Tony was burning up and horny as hell. He had dragged Tim of to a conference room. Demanding that he was going to the whole touching thing but Tim had only smiled his most charming grin and ignored Tony, smirking as he walked out of the conference room.
Tony growled and banged his head against the door, his love for Tim was going to kill him one day.
