My girlfriend has this friend who is so hot. We flirt with each other. We visited her a while ago and, while we were there, I had a chance to go through her panties’ drawer. I took a pair. She had a whole drawer full of silky, shiny, panties and thongs. On the way home, I showed my girlfriend what I had stolen. Much to my surprise, she wasn’t that pissed off. A few days later, we had sex while she wore those panties.
