neighbour eyeing wife

[Givemeextra]

After the suggestion of my neighbour, my wife is insisting to wear one piece....... Don't know whether to allow her or not........

You have allowed quite already. Wife is also seen enjoying in front of you. 

If you had blocked earlier, things would not have come to this stage. But you let things go loose. Moreover something wrong/missing in you OR some fantasy  you want to explore.  That's  why you allow someone to step up to your wife.

If you disallow now, wife go beyond your back. So why give chance to cheat. 

Just buy that one piece already.
