We were staying with my wife’s sister Jenna so she could attend some training for here work. Jenna was taking some time off and her husband worked for a fire department 3 hours away. So, most of time we were there, it was Jenna and me. This was the first time I really got to know Jenna since my wife, and I got married. One morning where we were going to go shopping, Jenna met me downstairs to head out. She walked past me and here denim dress was mostly unbuttoned in the back. I was frankly shocked. It appeared she was wearing a purple slip trimmed in black lace. I asked her if she forgot something and turned away. She said “oh, would you mind buttoning me up”. I was floored and said sure. I went to grab the first button and Jenna moved forward a little. I could see all the way down her back side. The slip had a lacey black slip up the back. I started getting a hard on and proceeded to button up the dress. She backed into me quite a bit and I am sure she had to notice my erection. She turned around, smiled, and simply said “thank you”. I wanted to say, well thank you but figured that was not appropriate.

We went to the big mall and split up. I went to the big sport goods store and she went her way. About few hours later we met in the food court. We went to get some Chinese food and I notice three bottom buttons of her dress around her rear were undone. I whispered in her ear that she needed to check her dress while we were standing in line. She ran her hand down her dress finding the gap where the buttons had come undone. She said, oh it is OK, I am wearing a slip. I was floored again. The entire time we were eating, I was thinking about her slip trying to talk. As people walked by her, there was allot of smiles and some laughter and I even saw a couple girls take pictures.

We headed back to the car and I noticed another button had come undone. The gap in the dress was quite large and I was starting to get another hard on. We got to the car as she noticed I was a bit uncomfortable. Jenna asked if I was OK. I did not know what to say. I stumbled my words and finally just said it, “I am a bit aroused at the sight of your slip. She said, “yeah I noticed after you buttoned me up at home”. We laughed it off and arrived back at the house. We decided to go swimming in her pool. As I was leaving the room to change, Jenna stopped me and asked “aren’t you forgetting something. I cannot do this myself””. She turned around and pointed to the back of her dress. Without hesitation, I obliged. Jenna dropped the dress to the floor and turned around and smiled. She was beautiful. She then said she needed help with her slip also and I immediately grabbed her pushing her up against the wall. I pulled her slip off while we were getting deeply passionate. She was wearing very lacey black bra and bikini panties. Jenna reached down my shorts and grabbed my stiff cock. We stripped each other of our clothes and jumped in the pool where I did her hard. She loved every minute of it. Never expected that ….
