I went out early one Saturday morning and when I came home around noon my sister-in-law and her husband had come over. They were out back with my wife. I see my sister-in-law in just bikini bottoms, her husband in swim trunks and my wife wearing nothing. Seeing my sister-in-law topless was a nice site since I had never seen her nude in any way before but having my wife fully exposed to her husband did not sit well with me. If she was only topless it wouldn't have been so bad but having her pussy on display like it was gave my brother-in-law too much of a view which I did not like. I called her inside and asked why she was fully naked in front of him. She basically said she knows he has seen naked women before and she was just one more he has seen now. We got into an argument with her telling me she can be as naked as she wants. I asked how she would feel if I was fully naked in front of her sister. She told me it was my body and her sister has seen naked men before. If I wanted to be naked in front of her it was my choice and she didn't care if I was.

I didn't know if she really meant what she said so I decided to challenge her on it. She went back outside to join them and I said I would be out shortly. I got fully undressed and walked outside to join them. I was now fully naked in her sisters presence and my wife truly didn't seem to mind. A few minutes later my brother-in-law went in to use the bathroom and when he came back out he was no longer wearing his swim trunks. He was just as naked as my wife and me. I was now hoping my sister-in-law would lose her bottoms but it never happened.

I do have to admit I was nervous as hell going naked in front of my sister-in-law and only did it to prove a point to my wife however it didn't really prove any point. She truly didn't seem to mind and all it really seemed to do was give my brother-in-law an excuse to get out of his swim trunks.

After they left my wife was quick to point out how my little stint backfired and all it really did was have her sister see my goods and get her brother-in-law showing his.
