Tony sank his teeth into the meat of Peter's shoulder. Hard. Brutal. Like he could bite deep enough to defy Peter's healing. Like he could leave something permanent, something Peter would see every time he looked in a mirror. A reminder of exactly who he belonged to. Who owned him.
His jaw ached with the pressure of it.
The word floated up from somewhere deep and Tony didn't even flinch from it. Didn't try to soften what he was doing. He bit harder, felt the skin strain between his teeth, felt Peter's heartbeat thrumming against his tongue.
If that's what this makes me… So be it.
Peter was shaking in his arms, fingers clawing at Tony's forearm, but he wasn't pulling away. He was arching into it. Pressing his throat harder against Tony's mouth like he wanted it.
Tony growled against Peter's skin, the vibration traveling through them both. The taste of clean water, soap, and copper. Just a hint. Just enough to make Tony's dick jerk against the small of Peter's back.
He sucked at the wound, tongue pressing into the indents his teeth had left. Peter whimpered, his knees buckling, and Tony held him up with the arm around his waist. Held him in place while he marked him.
When he finally pulled back, Peter's shoulder was a mess. Angry red indents from Tony's bite, the skin already darkening at the edges, and in the center where he'd bit deepest, tiny beads of blood welling up. The shower spray caught them, sent thin pink rivulets swirling down Peter's chest.
He brought a hand up and thumbed at the edge of the wound, tracing the crescent marks, feeling the heat radiating off the abused skin. Peter hissed, flinching into the touch instead of away from it, and Tony's hips jerked forward. A helpless little thrust against Peter's ass that made him grit his teeth.
Too bad it wouldn't stay like this. His bite. His brand on Peter's pretty little body. For everyone to see.
