He kisses Watson once, something gentle and loving, before the need to move makes him break away. He starts slow because that lets him move deep within Watson; he draws out only to sink himself in again, and he clutches at Watson's hip, holding him for leverage. His breath comes harsh against Watson's lips, and then the side of his neck, and his throat, as he trails his mouth elsewhere. As his mouth trails lower, into safer territory, his kisses turn to bites, and he nips at Watson, tasting him.

The slow pace can only satisfy him for so long, and after a few deep thrusts -- the purpose of which is more to lay claim, to possess than anything -- he speeds up, rocking his hips against Watson's steadily.
