How we got to this point is a long story. She and my wife have always shared clothes and she borrowed mine often not knowing in the beginning. On occasion she noticed that I had on something that she had worn. She knows we wear the same bra size as I once loaned her a strapless bra when she forgot hers.
Anyway we were visiting her and I had brought a nice linen shirt to wear for shopping and dinner. I got ready to go and went out to check myself in her big mirror. As I turned to look I realized that my white lace bra shined through my shirt like a light house on a dark night. I said s#487. She said, what's wrong? Told her I couldn't wear what I had on. She looked and said she really liked my shirt. I explained that the bra was too visible. Didn't you bring a beige one? Nope!
That's when she volunteered one of hers. We went to her bedroom and she pulled out two of her bras to ask which one I wanted to wear. Both had foam cups, but were different styles. She told me how she really liked one better than the other. I took both of them to try and selected the one she had suggested.
While shopping we looked at bras and she asked if I had any with foam cups. I told her I did, but thought they made me stick out too much. That evening she asked if I liked the bra and wasn't it comfortable. She said she liked the foam cups because it gives her a smoother look under stretchy fabric and I should wear them under t-shirts. My wife said she thinks they make you feel hot.
I gave it back the next day. She asked, You don't need it anymore? No.
