9.
Saturday morning, he woke with the light filtering into the bedroom, to see the two women still asleep under a down comforter. He rolled over, and was pulled back by the light chain from his waist still secured to the silk cord around the ottoman. His hands were free, and he realized he could unhook the chain and get up. At the same time, he saw the symbolic point of the restraint, and knew that Acacia would be displeased if he stepped out of his new role, and he knew deep in his mind he did not want her to be annoyed with him. He shifted to find more comfort, resolving to wait, and feeling the beginning of morning arousal, and the need to relieve himself, too.
He lay on his side, not wanting to touch himself, listening to the house creaking as the heat came up and the sun came through the sheer white curtains. The room, her bedroom, was more like a suite, with small sofa and chair and the ottoman he was tethered to, along with the plantation style bed and dressers. He turned when they began to stir, and Acacia slipped on her robe and came to his side.
"Good morning Five. I am glad you knew to stay, like a good pet. We have a full day for you, because there is a lot for you to learn in order to be useful to me. Start by presenting yourself properly here; Kneel." She slid the small quilt off him, and he shivered a little since he was still naked except for the body harness and collar. She stepped back to watch as he got to his knees, and arranged himself, with knees wide apart, back straight, head up, and arms on his thighs with palms upturned. He held the position.
Acacia reached out to correct his position with a few touches, having him put his knees wider and his body raised, correcting the angle of his chin. Diana came around the bed, in a short nightgown without a robe, so that he noticed the globes of her breasts cupped in the thin fabric, and her tan legs. He flushed as he felt his cock harden at the thought, and his need for the bathroom increase.
Acacia picked up his chain leash from the mahogany side table, next to a blue and white Chinese vase with fresh yellow flowers and handed it to Diana. "Just take him to the kitchen hall bath, Diana, then you can feed him. Five, let's be clear: when you are here, your body is mine to control, just like your mind. You are not allowed to touch that cock, specifically, so when you need the bathroom Diana or another sub will take care of that, and you will have to ask to be relieved."
Diana sighed lightly and took him on the leash, down the wide staircase to the kitchen entry hall and the small bathroom where he had showered. When he paused, she used the end of the chain leash to slap his ass sharply. "Ask first, slut."
