It's that promise, almost more than anything, that settles something deep inside him. That roiling pressure, the learned impetus behind mistrust and shying away from personal connections. When Steve promises things like this, that he's got Tony, that he'll take care of him- Tony believes it. Both because he so desperately wants to and because Steve makes it easy. This, more than anything else, has him sinking into this so much easier, giving in or up or both. Just giving all of himself to Steve come what may.

They've barely even started so he tries not to present as the shivering wreck he already is, but that's just what Steve does to him. He watches with stilted breaths and dark half-lidded eyes, almost hypnotized by the sight of Steve between his legs. The way he directs him, seems keen to take what he wants. Even if that just Tony's personal pleasure. He swallows hard, reaching, sinking his fingers back through Steve's hair in a few long, slow, passes. Tries not to tighten his grip at the back of Steve's head when he sinks into it. Takes him into the wet heat of his mouth in a way that renders Tony into a useless puddle on the bed.

A groan spills out from him, pushed up from his lungs and for a few moments his eyes roll back and closed focused on the intense feel of Steve's mouth around him. He immediately tries to separate his focus on that while also trying not to ride Steve's mouth, to not buck his hips up or grab him. He devolves the way he always does, into curses and warm murmurs of praise that he doesn't even really hear. "Fuck," almost sighed out on a pleased exhale, eyes flickering open again to catch the sight of Steve looking at him and that alone gets a harder throb from his cock while Steve's sinking down again. "Fuck your mouth is so fucking- ...perfect," words lost to him for a second as he trembles beneath him. And perfect doesn't even begin to come close.

Steve might not be as learned as Tony is, but it's the eagerness, the fact that he seems to always want Tony as badly as Tony wants him, that's all that matters. He feels dazed and incredibly needy all at once, remnants of those drinks hitting him all at once while he's there underneath Steve's devoted attention. Everything else, all the very intense troubles they're facing, seem to have completely vanished as he lets himself go, lets himself exist in this space they've crafted so carefully for each other. "God I want you so bad," he groans out like Steve's mouth isn't currently on his cock. "Every way I can have you, every way you'll take me- all of it- fuck-" Maybe none of it makes sense, he barely even hears himself. But it makes sense to him.
