It’s one of those fights.
They come back a little haunted and a little hot with it and a little, well...
“Steve,” Tony says as he steps out of his armor, touching his forefinger and thumb to Steve’s wrist from behind.
Steve turns into it, stepping closer into Tony’s space. It’s always so hard to get a read on him after missions like this. But now is fine. At least, he seems fine. In any case, Steve asks, “Are you okay?”
“Yeah, yeah, I’m fine. Uh... do you think you and I can disappear for a bit? Try out that hot tub thing we were talking about the other day?”
The hot tub thing they were talking about the other day is hot tub sex. Apparently, Wanda and Thor had given Tony the idea after a romp of their own.
“Let me just get out of all of this, and I’ll meet you in there.”
He’s such an eager beaver about this that he ends up tripping out of his tights, eliciting a laugh from Clint – because Clint, somehow, always knows when anyone in the mansion is hooking up. After the fumble, Steve shoves a towel around his waist and finds Tony in the little area off the pool where the hot tub and sauna are separated into individual rooms. He opens the glass door to a very pleasant sight of Tony luxuriating in the steam, hair damp and head thrown back. Beautiful.
“Took you long enough,” Tony teases as he looks up to Steve, his gaze turning hungry as Steve drops his towel to a nearby white plastic chair with holes in it.
“Mhm. Did take me long enough,” he replies, slipping into Tony’s lap.
Tony’s eyes light up in surprise and delight. Steve never does this. It’s always Tony on top – which makes sense and which he has no problem with – but something about the steam and the thick air and the odd romance of it is giving Steve a brave streak.
“I don’t have a strap,” Tony says into a kiss on Steve’s left nipple, shooting a jot of pleasure through him – he's so sensitive there, and Tony loves to play with his tits.
Steve tips Tony’s mouth up for a kiss, nipping his bottom lip quick. “Just kiss me for a second here.”
“Can do!” Tony laughs.
Their snicks echo against the tiled wall. Tony was right. The water being so warm, the atmosphere in here, it sets the tone for them to ease into sex nicely. Tony’s hands roam up and over his sides, his abs, his chest, eventually digging his fingers into Steve’s back and pulling him forward to roll his stomach against Steve’s dick.
He whimpers into Tony’s mouth, flipping them quick. It sends a wave over the sides of the hot tub.
“Will you be okay like this?” he asks as Tony digs his hands into Steve’s hair as he likes to do despite there not being much there for him to tug.
Steve snakes his hand over the swath of Tony’s abs, brushing up against Tony’s bush and settling at the top of Tony’s dick. A groan leaves his mouth into Tony’s the second he does. God, he loves Tony’s cock; sucking on it, jerking him off, pressing a vibrator there until Tony’s cumming on his fingers. He loves when Tony’s soft when they start and Steve gets him hard, he loves when Tony’s already rearing to go like right now. Tony breaks away to moan as Steve wraps his thumb and forefinger in a circle around Tony’s cock, jerking slightly and teasing at moving his thumb lower to Tony’s hole.
“Yeah, yeah, I’m fine. Fuck, I’m so wet.”
“We are in a hot tub,” Steve jokes back.
Tony’s response is to grab Steve’s dick and sink down on it.
He wasn’t wrong.
Settling his hands on Tony’s sides, Steve sets the rhythm up. Maybe it’s the temperature of the water, but Tony feels so much warmer than he usually does.
“Fuck, yeah, c’mon, harder,” Tony moans, tugging on Steve’s hair. Little zings of the pleasure-pain ignite him. But he keeps it slow and steady. Easy. Like the tides. Tony pulls harder. “Don’t tease me, Steve, seriously. I wanna make you come.”
It never fails to be hot, that, Tony being so focused on his pleasure when Steve’s inside. There’s this feedback loop that starts up the second Tony says it – Steve likes making Tony come, too, likes that it’s him making Tony feel that way, and that only feeds into Tony’s pleasure.
Tony raises off, nearly thrusts himself into Steve’s mouth with his tongue, pushes himself down on Steve’s dick again. With the water around them, the gravity of their skin meeting doesn’t hit as hard. If that keeps up, Tony will get frustrated, needing that friction to get off.
Heat spikes through Steve as he grabs Tony at the ass and lifts him up out of the water, turning them around to place Tony on the side of the tub’s smooth concrete rim. Tony ends up with his lower back hooked on the edge, their joined hips still submerged. He checks with Tony wordlessly that this is okay as Tony sets himself up on his elbows, getting a vigorous nod in response.
Steve keeps his hands on Tony’s perfect hips. His foot goes to the slanted seat they’d just vacated, his other foot on the textured bottom with his toes flexing to get the right leverage as Steve gives a few test thrusts. That’s good enough.
And then better. Steve fucks into Tony harder, getting Tony to make those combinations of moans and groans that signal Tony’s close to the edge and trying to get there faster. Tony clenches his hole rhythmically, swatting at Steve’s hand. “Jerk me off, I’m almost there.”
It’s just that, Steve doing exactly as Tony’s ordered, the sight of it filtered through the bubbling water still blasting through the jets, that sets him off.
“Can I? Inside?” Steve pants as the impending rise of his orgasm meets him harder than expected.
“Yeah, fuck, oh fuck I’m coming,” Tony starts in a moan and escalates into a sob.
Tony goes off in a burstfire. His orgasm around Steve’s cock sends him into a similar tailspin, his hips petering off to tiny thrusts before he snaps himself into Tony with one final spill.
Panting, Steve lets himself collapse onto Tony halfway, slipping out.
“Mmm,” Tony hums as he combs his fingers through Steve’s hair. “Feel good?”
His scalp is sensitive now, and he always loves this gentleness after having his hair pulled. With Tony, it feels more special.
“Very good,” Steve affirms as he presses a kiss to the apex of Tony’s scars where the mastectomy scar meets the open heart scar. “Very, very good.”
He pauses.
“Can we do this again?”
Tony laughs, the reverberations soothing Steve somewhat. “Definitely. Though, I don’t want to be paying for the cleaners to come more often, so we’ll have to time it out.”
“Deal.”
