Ignis smiled at Tony's possessive pronouncement because it was good to hear those words being said with all of the rest of everything going on in their world at the moment. The other troubles weren't on the older man's mind and the advisor was relieved. Sliding easily on his mate's lap, (the pants helped) he kissed back as eagerly as he was receiving. He still held back some though, trying to give the other every opportunity to quit and walk away.

The hands on his ass were perfect as that was the very thing Tony had mentioned liking quite a bit even before they were ever involved. And as he'd said, he let Tony have free reign of him and whatever he wanted to do. But as his head went back, Ignis kept enough of a mental leash on himself even as his hands dug into the broad shoulders for purchase.

When he could breathe and think he pulled back from what was going on and looked his boyfriend in the face. "Are you..sure about this?" Yes he was worried about Tony's condition and more than willing to back off even if his body would protest every moment.
