I have a good friend where I work and she happens to be female (I'm male). We are both married and the four (us and our spouses) have gone out to eat or have had dinner at each other's house several times before. Her and her husband are really good friends to my wife and I.

I've had the pleasant opportunity to catch a glimpse of the back of her underwear when her jeans gap open at work several times and I even mark on my calendar the days I see her underwear.

Well, 2 things happened recently that I now feel kinda badly about. She had a duffle bag at her desk with a change of clothes for when we go running after work. It rained that afternoon so we didn't run but she left her duffle bag at work for the next day. I was at work a little later than usual and ended up being the last one there. I started to leave and saw her duffle bag sitting on the floor of her cubicle. My curiosity got the best of me. I know she always wears high cut underwear (I can see the outline of her underwear through her jeans) but was curious about the size and brand of underwear she wear. I unzipped her duffle bag and her size 6, white, ribbed cotton, Jockey Elance high cut underwear was on top. I took her underwear out and held them up in front of me to examine them. I recognized the waistband from several other times I had looked down the back of her jeans and apparently, she wears Jockey Elance Hi Cut underwear almost all of the time. Next, I pulled out her size 36D, Platex Cross Your Heart Bra and examined it as well. My life is now complete. I know what size and type of bra and underwear she wears.

The other event occurred at her house. She and my wife were out shopping. Her 2 kids were taking their nap and her husband and I were sitting in their family room watching TV. The phone rang. Someone called from where he works and he had to leave. I offered to stay with their boys until his wife and mine came back so, he got ready to go and left. Curiosity again took over. I went to her bedroom and opened her dresser drawers until I found what I was looking for. My suspicions were correct. She had 6 pairs of underwear in her dresser. 4 of them were size 6, White, cotton, Jockey Elance Hi Cut underwear. The other 2 were also cotton Hi Cut underwear but I can't remember the brand (other than it wasn't Jockey and wasn't a name I recognized). They matched and were probably part of a 3 pack. The neat thing is one pair was white and the other had a light print pattern on them with dots and short lines (kinda like paint splatter) and small, light blue roses. I held her underwear up in front of me and examined them thoroughly. I looked through her laundry hamper and found another pair of her Jockey Elenace underwear and another pair of underwear that matched the other 2. So, that means she has 9 pair of underwear and was wearing her Jockey Elance Hi Cut Underwear that day. Being worried about how long I had been rooting through her underwear and expecting them to return soon, I put all of her stuff away and went back to the family room. 10 minutes later, her and my wife returned.

Now, whenever I look at her, I find myself trying to find out what underwear she has on. I don't know if it's obvious to her or not but sometime I feel a little ashamed for taking advantage of her like that. But, no matter how badly I feel at times, I still enjoy taking a peek at her underwear whenever the opportunity arises when her jeans gap open. Maybe some of you women could tell me how it would make you feel if someone took advantage of you like that.
