There's a bit of that promised howl even at first, a moan he'd not known was even there escaping his throat as two fingers stretch and enter, his body riding just slightly to meet the blessed intrusion. He stretches and shakes and there's a slight burn of pain to it that's exactly what he wants in that moment. That and Chris' words, soft promises of being paid back for what he'd freely enjoyed giving, what he'd never expected anything for but quakes in anticipation of now.

"Fuck. Yes. I want that." His voice sounds thin and reedy to his own ears even as it rumbles in his chest between panting breaths. He lets out an almost whimpered 'oh' as Chris kisses his cock and it jolts in response almost on its own, quivering and starting to drip. He's never been so brazen, he's never one to beg or even ask, just arrange things as he likes and give what his partner needs or wants. But bound and displayed with Chris so patiently stretching him and the pressure against his neck and the soreness already working its way into his abs for the tilt of the suspension attached to his collar all has freed his focused from what he would normally have shame over and instead he simply speaks his mind. No filters, no shame.

"I want you to fuck me hard and dripping, Chris." He wets his lips, mouth dry from the admission but forging ahead regardless, taking a deep enough breath that his chest rises noticeably. "I want to forget I even have a use other than this. I want to feel it for days."
