It's a heartwarming moment, learning under him, being taught how to please Shiro and figuring out what makes him shiver and moan. He's grinning smiling, leaning to kiss along his chest, biting softly at the patch of skin underneath his collarbones before he pushes one finger in.

He loves being bracketed like this, the way Shiro's cock twitches against his belly, pre-come pearling at the tip. The heat of him is startling, new, and he simply goes slow, gently urging him to relax so that he can press in deeper, down to the second knuckle. ]

Like this...? Relax for me. It's just me, and I wanna make you feel good.
