Susan and I were looking for a way to spice up our sex life when we decided to made it a game. The game was really just a challenge or dare the other one to see which of us could came up with something that the other one wouldn't do. To make sure that neither of us would just say that we would do it we had to do what the other one came up with. There was no prize for doing anything other than not being called a chicken by the other.
We decide that every Saturday would be the day that we would make the challenge. We flipped a coin to see who would go first. Susan won so the first thing she came up with was for me to shave the hair around my cock and balls, and stay nude all weekend. After I shave she said she really liked the look and that maybe I should keep them shaved. After all she kept her pussy shaved all the time. We have a hot tub in our backyard, and that night our neighbor, Pam, came over to use it with us. She'd been in it with us lots of times before. The 3 of us were good friends so it was natural for us to be nude. This time I felt a little strange with all the hair around my cock and balls gone.
I was all ready in the water when Pam arrived so she didn't see that. But after a little while Susan told Pam about our new little game. She had me stand up to show Pam. My cock started getting hard standing there as they both look at me. Susan thought it was cute me there with a hard-on. She ask Pam if maybe she like to watch me masturbate. I'd never even done this in front of Susan, so I turned red and sat back down. They egged me on some more and I finally gave in. I got out of the tub and started pumping my cock. It didn't take to long before I was shooting my load onto the grass. I got back in and we just soaked in the water just like we always had before. The sex we had that week-end was just like when we first got married 10 years ago.
For the whole week all I could think about was what I was going to challenge Susan to do. When Saturday came around I told her that she had to give me a blow job every time I wanted one for the rest of the weekend. I got 2 during the day. Then that night we went to a drive in movie. I parked the car about in the middle of the screen and 4 rows in front of the concession stand. In the middle of the first movie I pulled my cock out and told her to go for it. At first she hesitated, but then put her head down in my lap. When I saw 2 guys walking our way I almost told her to stop, but then decided not to. The guys walked past on the driver side so I knew that they seen Susan head in my lap. Knowing they seen her there was enough to make me cum. We left after that. On Sunday I got couple more blow jobs. One of them out in our back yard.
The following week I kept trying to think of what she would get me to do. On Saturday morning she told me that since she drank down so much of my cum last weekend. This weekend I would get to jack off when she told me. Then I would get to drink it. I'd never tasted cum so this was going to be something new for me. I told her that at least on one would see it like the 2 guys who walked past the car last weekend. She just smiled and told me to get started and to cum in a shot glass. After shooting in the glass, she stuck a finger in it and put it on my lips. Sticking my tongue out I got my first taste of cum. Susan then gave me the glass telling me to drink it down slowly. Once I had the glass empty she told me that since she got to swallow 5 loads it was only fair that I get 5. True to her word she made me jack off 4 more times that weekend. The last time she had me sit out in the back yard by our spa early Sunday evening. Right after I drank my cum I heard someone laughing on the other side of the fence. Susan say that since I had let someone see her giving me a blow-job. It was only fair that she let someone watch me shallow my cum. She told Pam to be out back and to peek though a crack in the fence.
By Monday I already knew what I was going to dare Susan to do. The weekend seemed like it would never get there. Finally when Saturday did arrive, I told my wife we were going to the new mall on the other side of town. I told that she should wear a dress and nothing under it 'cause we were going to show her charms off. At 35 she still has the body of a 20 year old so she went along with me and put on a white silk one that almost transparent. The front was so low cut that it was only at most an inch above her nipples. Her skirt was also very short.
So short if she bent just a bit, her bare ass would show.. When we got to the mall I could see all the men looking at her. I think she felt them looking to just by the way she was acting. The first shop I had her go into was a shoe store. She picked out 3 different shoes to try on. The salesman who was helping her got a good look at her pussy, 'cause she kept her legs opened wider then she really had to. We then went to the food court for a quick lunch. Right in the middle of the court was an elevated section. I pick a table on the elevated part by the stairs coming up. Susan was facing the stairs so and I sat to the side of her. That way I wouldn't block the view of anyone coming up the stairs.
After lunch I ask her if she was ready for the big challenge. She looked over and said she thought she had already done it. I told her that "that was just the warm up, and if she didn't want to go farther she could call it quits. She told me just what I was hoping to hear, "that there was no way I would get her to quit." We then headed to the next shop as I explained just what I wanted her to do. She gave me a shocked look, but said if that's what I wanted then that was what she would do. Once we got to the lingerie shop I went in with her and helped her pick out a couple of very revealing numbers. She walked to the dressing room while I browsed around.
A few minutes later I heard her call me. She had stepped out of the dressing room to show me the first one we had pick out. I went to her and talked to her for maybe a minute. She had given me and a couple of other guys, who were in the store a good look at her. She then went back in to put on the second one she took in. It was even more revealing then the one she had just came out wearing. While she was in the dressing room I pick up a pair of shinny black crotchless panties and a matching bra with holes were her nipples would be. The number she came out wearing the second time was so sheer it did nothing to conceal her tits or her shaved pussy.
