I have obtained a selection of women's lingerie over the years, and occasionally I wear it in the house. I tend to purchase lingerie, not because I want to wear it, more like, I like the feeling of the fabric and how it makes women look.
Today was different. I put it on and I actually filled the cup ! I couldn't believe it so I spent most of the day wearing it, and after carefully checking to see if it was visible under my clothes, I even ventured out, wearing the bra, which enhanced the look of my breasts, making me look just that slightly more feminine, although I think you would have to know, to be able to tell.
