Tony can feel the moment Bruce lets go. He smiles, letting Bruce arch and cry out, losing himself momentarily in the moment. And he looks beautiful when he does that. Really, there's no other word for it. Bruce's eyes clouded with lust and his body eagerly lifting up into his hand makes him moans softly in response. It's just too good to ignore.

He adds a second finger, taking him slowly as promised. Tony lets his lips slide over the head of Bruce's cock, and he lets his mouth take him in as he thrusts his fingers deep and rubs him with those strokes. He knows what he's looking for, and each thrust is precise as he seeks out that sensitive spot within him.

Tony bobs his head with a few careful motions. He doesn't want to get Bruce to come too soon, but he wants to soothe the discomfort by distracting him. His mouth teases the length of Bruce's cock while he stretches him, adding a third finger as he starts to move his hand with more purpose. It will make it harder for him to relax at first, but it'll be worth it.
