Hey Yoyo looks like we are posting at the same time.
some old but nice lingerie, clothes, facial masks etc etc. She'll ask "how come your wife is here? I thought you are separated?
Why not take it one step further and leave something that def lets her know that you are still having s@x eg. chocolate body paint in the fridge, that pair of handcuffs that must have fallen out of your bag into H's car. Now this is getting fun. I am sure you can think of something or some of that really tacky lingerie they flog on ebay.
Hehehe ~ must be fun playing the OW to the ow (notice she is not given caps as she is not worthy of them).
