He rifled through the drawer for a moment and scooped out the folded piles, and laid them down on the bed. Most of them were cute patterned numbers, basic panty briefs that came in three or five-count packs all the same cut. She had four thongs, each a different color: blue, red, gray, and pink. All were basic cotton like the black one he'd taken and placed on top of his fridge. There wasn't anything particularly sexy or lingerie-ish. They were going to have to go shopping. That might make for a fun outing later.
There was one pair under the others that had some promise. A pair cut in a Brazilian style with nothing but string between the front and back of the panty. Another pair of briefs was almost entirely lace. That was something. He took those and turned back toward Selene.
She was still standing in the display position, looking straight ahead and breathing heavily. Her eyes flicked to the door for a moment and then back to the wall.
Testing her resolve, Arthur reached out and cupped her breast. She didn't falter.
He brought his fingers together and grasped her nipple. Her breathing shifted, but she didn't break.
He squeezed it and pulled it slightly upward. Selene gave an audible gasp and lifted onto her toes. He spanked her, reflexively, and the loud clap of his hand on her round, pale, quivering cheek seemed to fill the room. They both glanced toward the door, but when Kat didn't come bursting through it after a few moments, they both let out a breath of relief. Hopefully, the sound of the movie covered it.
Selene was so aroused that Arthur could smell it in the air, and the slacks he was wearing did nothing to hide his bulge. It was almost painful. Still, there was something else he wanted to do. He walked back over to her dresser and opened the next drawer.
Her bras were much the same. There wasn't much to be said for variety, and they were pretty basic. Most of them were a solid color, one polka dot, but none particularly stood out as alluring or sexy. A critique he never thought he'd use for women's underwear. He scooped them out and laid them on the bed beside the panties. T-shirts were next, and then pants. Dresses and skirts were in the closet. He didn't pull them all out, but he did open the closet doors and sift through them for a moment, scanning her selection.
He picked up his phone, typed something on it, and held it up for her to read.
Master: These are all of your clothes?
Selene nodded and then paused. She shook her head, and looked significantly at the bed, then back to Arthur, and then back to the bed. He paused for a moment and then understood. He reached under the bed and pulled out a storage container. He looked up at her, and she nodded. He lifted the lid off the container and was confused for a moment, then smiled.
Ren Faire costuming of various types. There was a corset, some skirts, a few folds of silk, bells on a chain, a sheer wrap with dangly 'gold' coins on it, and perhaps the most promising costume pieces of all: a chainmail bikini. He smirked as he set them on the bed and looked back at her.
"That's all?" He asked softly.
She nodded silently.
He picked up the phone again, typed, and then held it up to her to read it. It was inconvenient that her sister was in the other room, but the thrill of trying to do this when it was a secret they were trying to keep from the person on the other side of the door added an element of fun to it. He could feel the thrill of it, like electricity, the same type of electricity that jumped between them when he ran his hand across her hip and gently rubbed the spot he'd spanked earlier.
Master: We need to take you shopping for more lingerie. If you're my slut, you will wear slutty underwear as often as possible.
"Yes, sir." She whispered so softly Arthur wasn't even confident he'd heard it.
Master: Maybe we'll buy you some slutty clothes too. Something for me to enjoy when we're with other people.
"Yes, sir." Selene's whisper was louder that time, more assertive.
Master: At ease.
Selene looked confused for a moment and then dropped her arms to her side. She hadn't realized how long she'd been holding them behind her head until she felt the relief of moving them again. She rolled her shoulders and shifted her feet a little closer together, relaxing.
Arthur rifled through her panties and pulled out the red thong. He handed it to her, and she held it. He nodded at her, and she nodded back but didn't move. He smirked and pulled up his phone again.
Master: Model them for me.
Selene's mouth formed an o as she expressed understanding and nodded. She stepped through them as quickly as possible, one leg and then the other, and pulled them up and on. She lifted the straps a little higher than usual, running them over her hips, but he let her. He sat back down on the bed and spun his finger around as he pointed it to the floor.
Selene spun in place, doing her best to show off her body for him as she did so. He offered her the bra next, red, though a slightly different shade. She hesitated but put it on, fastening it behind her back after giving him a questioning look. He only smiled and then went to the closet. He pulled out a white sundress, the material wasn't sheer, but it was thin. Thin enough that the red would show through as pink in any decent light.
Her eyes went a little wide, and she swallowed thickly. Arthur stared her down, and it didn't take long for her to look down and nod. The silent 'yes, sir' was all he needed. He gestured for her to raise her arms, and she did so. He slipped the dress over her, straightened it, closed it, and stepped back to admire it.
It was shorter than he expected, coming up to two inches above her knee. It was tighter too and a little nicer than what she usually wore, which was why he probably hadn't seen it on her before. He walked around her, taking it all in. It clung to her torso rather tightly until it flared at her waist. It was thin material, and the red was barely visible through the top. The straps were thin enough that the bra straps would certainly show as she moved throughout the day.
He looked at it for a moment and then nodded. Then he put the rest of it away, group by group, back in the dresser. Finally, whether because he planned to all along or because he saw Selene's nervousness and took pity on her, he pulled her blue open-front half-sleeve sweater out of the closet, set her arms through it, and draped it over her shoulders over the white dress.
"That's your outfit for tomorrow."
"Yes, sir." Selene whispered with a thankful tone in her voice.
"Now." Arthur whispered with his lips less than an inch from Selene's ear, one hand on her waist, the other on her arm. His grip was tight, and his words were quiet but hard and steady. "I'm going to sit on that bed. You're going to use that mouth of yours to pleasure me, and then you're going to straddle me and ride me for all you're worth. If you make enough noise to bring your sister in here, you're going to explain to her that you're my slut, and that you just couldn't help yourself. If you stop riding for any reason before I cum, or if you cum without permission, I'll add it to your ever-growing list of punishments. You've got three coming your way already"
He looked to her to make sure that she understood, and she looked apprehensive but nodded. She glanced at the door more than once as Arthur settled on the bed with his back against the wall. There were no particularly erotic moments of Lord of the Rings: Return of the King as it played on her laptop at full volume, so he wasn't sure how well this was going to work. Yet he was still aroused, so he looked at her instead.
Selene started to take off the sweater, but Arthur caught her attention and shook his head. She looked confused for a moment but decided to play along. She watched as he settled into the bed and unbuckled his pants. He beckoned her forward with a finger, and she came forward nervously, leaning over the edge of the bed so that she could reach as her hands found his thighs, reached inside his pants and pulled him free. He was already erect, and she did her best to use her mouth instead of her hands.
She started slow, using her tongue on the tip and underside. After a few minutes, she felt Arthur begin to wilt and looked up, confused.
Arthur sighed and looked over at the door, then at the laptop, then back at her. He pulled up his phone and typed for a moment.
