I was married to the oldest sister, Mary, one of three.

The next sister was Carrie and the youngest was Paula. Mary and I had a alright sex life but Mary was kind of shy.

Her other sisters weren't and let me know all the time. When we were first married, for a year we lived with her folks in a rather large house. This was to save a little money.

One day after work on a hot summer day, I came home to an empty house. At least I thought it was. Out in the back yard Paula was sun bathing.

Paula was a very tall girl, with long legs, a nice soft place, cone shaped breasts, and a average face and she always wore these out of date glasses. The way she dressed and acted, she was a plain Jane that hardly anybody ever looked at. Today she was laying on a lounger in a tiny white bikini. She kept misting herself with water to tan quicker. From my view in the house, 2nd floor, I could get a profile look. The misting made her suit almost see thru. It clung to her breasts and you could see the nipples. Before long I was hard and had to stroke myself while watching. After about 10 minutes I heard a noise and looked behind me and there was Carrie at the end of the hallway massaging her breasts as she watched me. She told me that I should be ashamed of myself but since I caught her she wouldn't say anything. And with that she turned around and left. When I turned back to Paula she was now on her stomach. I decided to walk outside and say Hi. I stuffed my length in and tried to get my underwear to keep it down. I walked to the end of her chair and sat on the grass and said Hi.

She said Hi back and just kept laying their while talking. I could see up between her legs and the crack of her soft place where her suit was snug. I couldn't help myself, I took my length out and started jerking off, while trying to talk to her as if nothing else was going on.

Suddenly Paula said you know its interesting but I can see the whole yard in the reflection of the house deck door.

I froze and then she said don't stop.

She said why don't you take my bottoms off for a better look.

Just touching her soft place made me grow another inch.

I couldn't take it anymore, I stood above her soft place and jerked off and shot cum all over her back. She said, That was fun. Then we heard a car door slam and she shot off the chair and ran into the house. It was great to see her naked soft place move. I ran behind her and went to the bathroom. It was hard to play innocent the rest of the day.
