Bucky practically purred when Billy's fingers tugged at his hair, rewarding his partner with more enthusiastic sucking. If they kept on all night as Bucky suggested, Billy would likely discover how much he liked having his hair played with. He had great hair for it too, long enough for Billy to get his hands into and tug as much as he wanted.

Bucky let his hand fall away and his throat relax with that slow roll, using the motion to take Billy all the way to the root. He held his partner's gaze, sucking and working his tongue against Billy's cock for as long as he could, eyes crinkling at the corners with the praise. Even when he needed to back off he didn't go far, working the head between his lips as his left hand reached down to palm himself.
