I gave Erika 30 minutes to clean herself up and come back downstairs. She had 5 minutes left. I sat on the couch and flipped through the channels. Not really paying attention to anything on TV, I was more interested in what had just happened.

My incredibly gorgeous eighteen-year-old tenant couldn’t pay her rent so she thought she could barter sex in exchange. I countered her offer with mine: be my sex slave for a month. She accepted.

I looked around and saw her clothes and underwear scattered on the floor and smiled. I had just finger fucked, throat fucked and ass fucked her. I wanted so badly to fuck her pussy but I had to wait for her birth control pill refills tomorrow.

I had so many ideas and couldn’t wait to try them all: slutty clothes, toys, sex in public. I wanted to tie her up and fuck her, I wanted to slap and spank her. Oh, did I have ideas. My dick started to get hard again. Two minutes left.

Just as her time is running out, Erika come upstairs. Her hair is wet again but no makeup, and wrapped in a towel. That made me upset. I had given her some rules to abide by and she had broken one already: unless told otherwise, you will wear nothing but a bra and panties inside this house.

Erika walks up to me, smiling. Calmly I get up, still naked but with a semi-hard on, and asked her if she remembered anything I had told her. She gives me a puzzled look and I remind her about rule two. Her eyes widened and immediately removes her towel and throws it on the couch.

“I’m sorry Master,” Erika says standing naked. I eyed her perfect 34C tits and her smooth shaved pussy. My semi-hard on became a full hard on.

“Sorry is not good enough. You will need to be punished,” I said. The first punishment needed to be good. I sit back down on the couch with Erika standing before me.

“Go downstairs put on some underwear and wait for me,” I said dismissing her. She apologized again then quickly left.

I let Erika sweat a little over what her punishment might be. After a few minutes, I got up went to my room and got dressed then walked into the basement.

Erika was standing in the basement living room in a red bra and matching red panties. I walk past her and go into her bedroom. I look in her closet and pull out a blue mini dress. I threw the dress at her and told her to dress and meet me upstairs. We were going out.

The car display watch read 8:45 as we pulled into the mall parking lot. There were a few cars still parked in the lot. We walk into the mall and head right for Victoria’s Secret. The store was empty, except for the cashier who was on her phone when we walked in. We walked around the store looking for something nice for Erika to wear. I picked up a red negligee then we went towards the dressing room in the back. I sat outside and told her to try it on. A few minutes later Erika pokes her head through the dressing room door and asked me to come in. I looked back at her and told her to come outside.

She swallowed hard and looked around to see if anyone else was there. There wasn’t. Erika opened the door and stepped out. The red negligee did justice for her curves. The material hugged her body all in the right places. I told her to swirl around so I can see it from all sides, she complied.

“Damn, she is fine!” someone exclaims.

I look to my left and see a middle aged, tall white man standing at the entrance to the fitting room doorway. Erika freezes. She immediately turns bright red, the same shade as her underwear and negligee. Right away Erika tries to cover herself with her hands.

“oh god,” she expresses.

This is perfect, I thought. I got up, told Erika not to move and walked over to the guy and stood next to him. Both of us looking at Erika.

“You think that negligee is right for her?”

“Fuck yeah,” the guy exclaims. Not taking his eyes off Erika.

“I was looking for something sexy and slutty, not sure if this is it,” I said.

“Dude, TRUST ME that is sexy. But you know what? I saw something else a few minutes ago that I think would look great on her,” the guy said.

“Why don’t you get that,” I said smiling.

Erika fidgeted more and couldn’t take the humiliation. She lowered her head and tried so hard to keep herself covered using her hands.

“Be right back. Don’t leave,” the guy says. Clearly he was talking to Erika and not me.

I walked back to Erika who says,”Oh god. This is so embarrassing. Can we please leave?”

“The guy went to get you something to try on. If we leave, it’ll be rude.”

“Oh god please. I know I should be punished, can’t you punish me at home. You can slap me again. You can slap me as much as you want,” Erika says.

Before I can answer the guy comes back with what looked like a white skin tight shirt.

“Sorry it took a while but can’t find any leg warmers or tights to wear underneath. By the way I’m Tom,” Tom says and extends his hands.

I shook his hands and took the shirt from him and gave it to Erika. She took the shirt hesitantly. She tried to turn around and go back into the dressing room when I tell her she should just change in front of us. After all the red negligee was so thin and transparent that nothing was left to the imagination.

She stared at me and cringed. She knew I was right. If it wasn’t for her bra and panties it’d be like she was standing in the store, in front of Tom, totally naked.

Erika slowly slides the thin strap off her shoulder. Her hands shaking and face turning redder and redder by the minute. She slides the other strap and off and wiggles out of the negligee. Tom exhales seeing Erika minus the negligee and mutters,”oh my god.”

Erika quickly takes the white shirt, courtesy of Tom, and pulls it over her head. The shirt/dress hugs every inch of her body and comes down to maybe three inches past her thighs. The material was slightly thicker than the negligee, but not by much. Clearly she needed leg warmers or something if she wore it in public. But I don’t think this was intended to be worn in public. Tom was right, this looked absolutely perfect on Erika. I told Erika to spin around so we can see from all angle. Her backside looked awesome. The material hugged her ass like it was molded for her.

After having Erika model for us –which included spinning around a few times, walking up and down and bending over– I decided it was time to wrap up. I tell Erika to get changed, and thanked Tom for his suggestion. In a blink of an eye Erika disappears behind closed doors and Tom’s smile vanishes.

“She is some work of art,” Tom finally says. He hands me his business card and says I can call him anytime to help pick out things for Erika.

A few minutes later Erika steps back out in her blue min-dress with the red negligee and white shirt in hand. I calmly walk up to her and slap her.

“In case I didn’t make myself clear, you don’t get to tell me how and when I can punish you.
