Prey species always got nervous over being the center of attention.
It was in their blood, of course. Those tricky little instincts that carried over from a less civilized time. The survival drive to go unnoticed, quietly making their way through the world either looking over their shoulders or blending in with the mass of a group. It may have been millennia since anyone actually had to live like that, but even still-- the instincts lingered, and Peter was no different.
And it wasn't like he had a general nervous constitution. He was all smiles and bursting energy most of the time, bold where he needed to be and not afraid of a scrap, but when it came to attention? He would blush and stutter and squirm under praise, casual stream of chatter dropping to a mumble while he shifted from foot to foot, and Tony--
Well. Tony was a predator, and nothing kept his attention better than nervous prey, ready to bolt.
Of all the wonderful things about an unorthodox predator-prey relationship, this was Tony's favorite. The cycle, the game of it. A compliment given with slow, deliberate intent that made Peter's ears go up in alarm even as he flushed with delight. Peter sprawled on their bed, chest heaving and cock straining against his boxers as he waited in frozen anticipation for Tony to stalk over to him, their eyes locked. The fever it drove both of them to, knowing that the more Peter's instincts told him to run, the more Tony's instincts would tell him to chase.
Tony really hadn't had nefarious intentions when he'd circled around behind Peter in the lab. He'd needed something from across the room, and it wasn't his fault that Peter was in a good mood that day, working on a favorite project with his tail twitching in eager delight.
But of course Peter heard the pause in his footsteps when Tony stopped moving, and his ears went straight up.
Tony grinned, toothy, and didn't change a thing. He just let himself drink Peter in, the strong muscles of his shoulders and the softness of his ears and tail and the plush curve of his ass. Gorgeous, delicious, and most importantly, Tony's.
Peter's ears started to twitch, angling to try and capture the sounds of Tony behind him, and the line of his back grew more and more taut the longer Tony lingered. His sweet prey scent deepened into something decadent and heady, thick with arousal and adrenaline alike at the instinctive knowledge of Tony's heavy gaze on his back.
It was almost irresistible, but the same instinct in Tony that wanted to pounce and bite and claim knew that catching his prey would be that much sweeter if he waited, watching with fixed, proprietary attention for the moment that Peter's nerves would fail.
Peter shuddered, and Tony was on him in an instant.
"Tony," Peter groaned when Tony crowded him against the lab table from behind, hands roaming all over that beautiful body and teeth sinking into the soft skin above his shirt collar. "I-- ah!-- I was really in the zone--"
"I know, your little cottontail was just twitching away," Tony murmured, giving Peter's ass a squeeze before he reached to start undoing Peter's buttons. He left a trail of bites up the side of Peter's neck, savoring the taste of willing prey on his skin, savoring the way he could almost hear the thrum of blood rushing through Peter's veins while his rabbitheart raced and raced.
He got Peter up on the table once his shirt was open, pushing the fabric off his shoulders to bare more of his skin to Tony's teeth, a beautiful canvas that Tony couldn't wait to ruin. Tony purred as he sucked at the delicate skin of Peter's collarbone, nipped at the line of his jaw, fixed his fangs into the meat of Peter's shoulder, and all the while Peter's scent only grew more and more delicious while he shivered and gasped and rutted against Tony's weight.
"Haven't you had enough?!" Peter panted finally while Tony nipped him again and again, like his issue was with the bites and not the way Tony was angling himself away from Peter's urging hips every time he sounded like he might come.
He was gorgeous with Tony's marks all over him, darkening circles and rings of uneven pink indentations littering his body. Each bite was more decadent than the last, and Tony intended to eat his fill.
"Nope," Tony said, teeth set in firm points against Peter's skin as he grinned. "You smell too good."
