His grip tightened around her possessively, and perhaps just a little too tightly. It was something he would hardly notice unless it was pointed out to him, but at this moment he was more involved in other matters. Namely, the smooth column of her neck that looked completely delectable in this lighting.

Without thinking, his tongue peeked out to wet his lips and he pressed them against her throat. Small pecks and nips trailed up to her ear where he planted a firm kiss. His many earrings jostled and jingled as he moved his head back down along her neck and the hand that had been clutching the metal bar on the seat found its way along her side.

He was somewhat aware of what was deemed 'appropriate display of affection' in a public setting, though it really all came down to whether he cared or not.
