Possessive
The computer chair squeaked ominously as Duo shifted his position on Heero's lap, his mouth on his as Duo's hands roamed up Heero's shirt and thigh. Heero tugged on Duo's braid while undoing the buttons of Duo's shirt. Duo pressed Heero further back against the chair and sighed contentedly against him before deepening the kiss. Duo had to be careful-last time they did this, he knocked the chair back. Not like that necessarily stopped anything.
Duo undid Heero's jeans and tugged at them while Heero tried to yank Duo's shirt off, their kissing matching the intensity of their actions. Duo got to his feet and effortlessly pulled Heero with him. Duo's back met with the edge of the desk and he pulled Heero closer, his fingers in his hair.
"Mine," Duo whispered against Heero's lips. He slid his hand underneath Heero's boxers and stroked him. "Every last part of you is mine." He nipped Heero's lip, his jaw, his neck. Heero tugged Duo to the floor so there was no danger to his computer from flailing limbs.
"Yours," Heero whispered in Duo's ear.
