Matching Jewellery For Wife And Mistress

I was shopping yesterday for a piece of j*wellery for my mistress. I'm travelling for business to her part of the country tomorrow I've told her to book a half day off work, so, if all goes well , and I can get my meetings done tomorrow morning, I should be should be fucking her all tomorrow afternoon. It's been a long time since I last got my way with her. Ivr written about her on here before, she's a not younger than I am with a gorgeous body a shy nature but a very horny slutty need for sex. She's single but seems very happy with her status as my bit on the side. Whenever I do manage to get to see her she's always super ready to indulge my needs.
Anyway, the j*wellery..

I found her some very attractive unusually shaped ear rings which I think will suit her really well. I asked the girl in the shop to hold them in front of her ears so I could get her a better idea of how they would hang. They were really nice.
But I couldn't decide whether to get the gold or the silver ones. I had her hold each one against her ear several times , she was a pretty young girl and I think enjoyed doing this for me.
So in the end I bought both pairs, I thought it would be quite kinky to have both wife and mistress wearing the same design. Now I just have to decide who gets the gold ones and who gets the silver....
