Heero exhales a heady sigh when Duo's lips meet his neck, a little surprised at how the feeling immediately sends a subtle shiver down his spine. He'd known on an intellectual level that some areas would be more sensitive than most, but perhaps hadn't expected it to feel even better than trading kisses on the lips. His eyes flutter closed, his head tilting aside to give Duo the room to explore while he presses light kisses beside Duo's ear in return, wherever he can reach.

Duo's fingers twisting into the wet fabric of his tank only sends another wave of want through him. Heero is glad, in a way, that the sensation is already familiar to him - it feels less imperative to immediately take care of that rapidly budding arousal than it did the first time. Heero feels a little more freedom to experiment, to slip his hands beneath Duo's clinging t-shirt and push it out of the way so he can appreciate the lean muscle beneath his palms.
