"You okay there?" He murmurs, letting his eyes slide closed again as he just relaxes into the hold and pets him absently. "I can take care of you in a minute if you haven't come yet." Tony's not going to make assumptions. Steve probably could have brought in a marching band at the end there and Tony wouldn't have noticed.

"Thank you for that, by the way." He drops a soft kiss against the top of Steve's head. It just seems polite to show his appreciation for a blowjob that good.
