Just a little stand-alone implied Steve/Tony bathroom drabble, Tony POV!
Tony nicks himself with his razor and swears loudly. A bead of blood wells quickly in the cut and he dabs at it with tissue, grumbling under his breath as bright red stains blossom on the white material.
The shower on the other side of the wall in front of him hisses and stops as Steve turns the faucet off.
Tony hears him whistling as he steps out of the shower cubicle, some old song by Dean Martin, and then he starts to sing, words drifting in the air, and Tony vaguely admits that the captain has a pretty good singing voice.
He carelessly discards his razor and pats cologne on his skin, wincing at the sting of it on his cut. Footsteps pad across the tiles behind the wall and there is a rustling of fabric as Tony assumes the captain takes a soft, white towel from the rack to dry his hair.
And suddenly, he's curious.
He sneaks a peek, eyes appearing round the left of the wall.
The captain is stood in front of his own mirror, still humming, wearing nothing but a towel, and a small one at that, Tony notes with a raised eyebrow. He wonders distantly if someone hid all the bath towels on purpose. Then he shakes his head to clear the thought as it wanders off down an entirely inappropriate path of its own accord.
Still…
He looks again, fingers curling round the corner tiles.
Tendrils of wet hair clinging to the back of his neck, water droplets glitter on the captain's damp skin, and several run down his back, trickling into the dimples at the base, collecting in the hollows of the muscle, and Tony realises that he is unashamedly staring now.
He turns back to his mirror, and slaps himself quietly in the face with one hand, muttering, "Nope, no, don't think so. Tony, you do not fancy Captain America."
He looks at himself reflected in the mirror and raises one eyebrow.
"Yeah, right," he breathes, in an exasperated sigh.
Slowly, he leans back again.
Steve is towel-drying his hair, whistling. The rough motion makes the towel round his waist begin to slip, and just before he bares everything, the captain catches it with one hand, but not before he reveals his naked ass.
Tony exhales, eyes wide, "Oh… my…" but the captain quickly pulls the towel up round his waist again, firmly tucking the edge in place.
Tony can see the captain's blush in the mirror.
He whips back, hands on the edge of the sink, repeating the word "no" over and over under his breath.
He shakes his head roughly, attempting to banish the thoughts and urges whispering in his ear.
"God damnit get a hold of yourself, Stark. You are not allowed to want to have sex with Steve Rogers!"
He exhales slowly, unsteadily, and his breath is a mist on the mirror as he leans forward to press his forehead against the cold glass.
Then he mutters, absently, "He does have a fantastic ass, though."
