Kieren's surprisingly strong hands curl around Sirius's hips, holding him in place, and Sirius stills with another shudder, head tipping back as Kieren's mouth continues on him, taking him impossibly deep.

He feels nearly mindless with how good it feels, can only imagine how it must be for Kieren right now, to both be providing as well as feelings this pleasure. He wonders if Kieren can feel the weight of Sirius's dick in his mouth or the stretch of his throat, or if instead he's only feeling wet warmth surrounding his cock, the hard press of fingers around his hips.

It's that idea that makes him remove his hand from Kieren's hair and instead bring it to his own, curling in the thick, wavy strands and tugging lightly in the way he'd like to tug Kieren's. His hips buck forward instinctively and he settles his other hand low on his belly where he can feel his own shaky breathing as well as the light trail of hair below his navel.
