I really need help and strategies to handle this matter. My wife sister came three weeks ago to live with us. She is 22 yrs. My problems now is her dressing mode which my wife is not careful about.

This lady always wear see-through singlets and night gowns. She has big breasts and always displaying them. I don't know how I will tell my wife to talk her sister to cover herself. She may feel bad that I'm attracted to her sister.

During the sallah holiday, I was with her alone because my wife don't holiday in her place of work, I have to leave the house and stay in the accommodation given to me in my place of work.

This morning, I carried my undies to wash, she crossed me and told me to give it to her to wash, the towel she tied because she was going to bathroom before was removing and showing her full breasts and she never worry about that.

Our marriage is just one year and I never cheated on my wife and she trusted me but her sister is really giving me emotional trauma. Can you imagine, yester night, my wife went to a programme, I was with her. So I called her around 8 pm that we should pray and go to bed. This lady came with a see-through night gown with a push up bra that put all breasts outside. Even her pant color was visible. I tried to control myself....

Even this morning, she came for prayer with the same gown and my wife did not caution her.....
How can I handle this matter?

I think your wife and her sister may be trying to test your fidelity since she isnt saying anything about it and often leaves u alone at home with her sister, but that is only an assumption. Despite how difficult it may seem, you should try to bring up the issue and trash it out with your wife to avoid falling into the badly pressing temptation, after all your partner is meant to be the closest person to you. Effective and sincere communication is the only way to solve this.
