Klaus shrugged, "I like to be as efficient as possible." He said, like he was being entirely reasonable as he pushed himself out of his own shirt and then his pants, kicking them away without much show to it beyond simply the pure pleasure that came from being able to see him out of his clothes.
"Now I think that means it's time I played with my gifts." He was teasing, a playful smirk on his face as he planted a knee into the mattress and leaned down over Regulus, kissing him once more and with his free hand found his hand tangling their fingers together once more like he was merely holding his hand and then raised it slowly while he pressed his hips to Regulus' in slow rolling thrusts driving himself against Regulus' hip and then pressed Regulus' hand to the mattress just over his head.
He pulled his mouth away and let his lips trail down over Regulus' jaw, and then down his throat to his chest, mouthing over clavicles and then his chest as he worked lower, tracing out the shape of muscles with his tongue. He released Regulus' hand so he could continue his downward path and wrapped a hand around the base of his cock gripping him firmly, and running his tongue up from the base to the tip in one long stroke.
