Crowley winced, a slight thing, at the feeling of the nails down his flesh. He knew the Mark was likely going to be a touchy subject, but he'd leave it to Alexi to bring up, not stupid enough to will that onto himself.
Once the other was naked over him, he gave a dutiful nod, craning his neck down to kiss along Alexi's chest and stomach, on his way down to his brother's cock. He had the ability to contort his body into almost unnatural positions, and no shame to do so around Alexi, considering it was for his pleasure. Pressing his lips to the head of his new Lord's cock, he let his mouth slide down, taking the head into his mouth to suck at with obvious practiced skill.
