This is new. Having him like this. Terribly exciting, actually. Byleth nips at the cuff of his ear as he takes the rope from him and at last ushers them to the bed room, walking him back and giving him a light shove down to the bed. The rope runs through his hands, and he pulls a portion of it taught. Good. This is where he excels. A good, pliable sub beneath him, ready to do as he asks. Ready to be spoiled and praised and utterly ruined.

"Robes off. Now, please." He says, as he moves to fetch a few things from the closet. A small box and a long metal bar. He sets them on the bed as he joins Emet at last, carefully arranging them.

"We're going to play a few games." He guides the mans hands up above his head, pinning his wrists to give him a demanding kiss that trails down toward his ear, so he can continue in a low, near-whisper. "You are going to do exactly as I say. You don't come until I say you do. If you fail... I'll make you regret it. Understand?"

With that, he lifts away and goes about actually binding his wrists. First together, and then to the bar across the headboard of the bed. Once he's tugged on them a bit, making sure they're secure, he moves down. Hands stroking Emet's thighs, coaxing them to part.

"The other game we're going to play, I have adjusted to suit your penchant for organization. For discovery and proper documentation." He chuckles, binding one of his knees to that metal bar. "I am going to test you in different spots, and you tell me how sensitive it is, on a scale of one to ten. One being not at all, and ten being neigh unbearable."

Once his knees are bound propped apart by that bar, unable to close, Byleth surveys his handiwork with a small sense of satisfaction. Now he can truly begin. Eyes drift down to the now quite full erection.

"Well. Someone's excited. You look good like this. Do you want me to touch you now?"
