Michelle and I were in the outside shower when my sister Lori banged on the door telling us to hurry up. Michelle and I looked at each other in frustration.
Michelle called out saying she would be out in a minute and silently mouthed to me sorry. I stood there with a raging hard on. I was just dying to finish. I reached down and began to stroke myself because I knew, as she reached for the shampoo, she was not going to upset my sister and that if I wanted a release then I was going to have to finish up myself.
She looked at me with angry eyes as I began to stroke myself, watching the shampoo and water run over her tanned body, down her breasts, over her stomach, down her legs and puddle at her feet. "Don't you dare! You save that for later and I promise it will be worth it."
I growled in frustration and released my painfully hard cock. Michelle was quick about washing up and when she was done she quickly left the shower.
It didn't take me that long to get clean but by the time I got out of the shower the girls were gone. They had left a note saying that they were going into town for dinner and shopping.
With nothing to do and left on my own, I went out on the deck with my book and did some reading. It was after 9:30 when the girls came back. They had bags in their hands and were giggling. It was good to see both of them having a good time, especially my sister.
I asked how their time was and what they did. Lori giggled more. As did Michelle. They told me that after dinner they did some shopping around town and picked up a few articles of clothing and asked if I would like to see them.
I'm a guy, clothes don't thrill me. But I did not want to ruin their good time that they have been having this evening so I agreed that they could show me. They turned happily on their heels and headed to the bedroom. I was anticipating them just taking stuff out of bags and showing me but I guess I am getting a fashion show.
Out first was my sister Lori wearing a modest flowered sundress. She did a little spin on her toes showing off all sides. It was flattering to her. I told her it looked lovely. It did.
Then out came Michelle also showing off the sundress she had purchased. This one was more of a solid color. She did a model strut out into the living room and then turned and model strut back to the bedroom. It was also a lovely dress.
Lori told me to wait because there was more and followed Michelle back to their bedroom. Michelle was next out showing off a short skirt and tight fitting top that exposed her midriff. I could tell that under her top there was no bra. And when Michelle turned and spun for me I could not see any panties. Needless to say, I found that very arousing.
Michelle stood off to the side and out came my sister. She was wearing shorts and a top. Again I told both ladies that they did a great job with their choice in clothing. They returned to their room to change and once again came out to show off for me. First Lori showing off her new bathing suit. This one was more daring than she normally wears and I am pretty sure that her best friend persuaded her strongly to purchase the bathing suit. It showed off more skin that she usually went around exposing and my mom or dad would not approve of this bathing suit at all. And I think that Lori knew that too as she said to me 'don't tell mom or dad." I assured her that I wouldn't. Now, it was now time for Michelle to come out.
She came strutting out in a bathing suit that was jaw dropping. Barely there. Lori giggled when she saw my reaction and told me that Michelle picked that out with me in mind. I guess Lori is accepting of the idea of Michelle and I now.
The bottom of the bathing suit rode up high over the hips with the material barely covering her pubic area. The top was just a string with hardly any material covering her nipples. It was amazing. Arousing.
Michelle came out to the middle of the room and did her turn and with her back towards me leaned down and pretended to wipe something off the top of her feet but the bottom of her suit tightly rode up between her magnificent ass cheeks. Nothing was left to the imagination.
Michelle strutted back to the bedroom. Lori remained and told me that Michelle has one last outfit to show me. That she got it with me in mind.
My sister, before returning to her room, informed me,"She likes you a lot, you know. Like a lot a lot!"
Michelle then comes out wearing sheer, see through bra and panties. I could see her nipples through the fabric, her beautiful bare pussy, everything was on display in this outfit. She walked up to me, leaning forward, placing her hands on my knees, and in a low sexy voice asked, "Do you like?"
I was speechless. All I could do was nod my head. She looked down at the tent in my shorts and smiled.
She stood upright and turned towards the bedroom and swished and swayed her ass as she walked back to the bedroom she shared with my sister. She looked over her shoulder seductively with a smile before closing the door behind her.
