Best Friend's Panties

My wife's best friend needed some work done at her home, so I stopped by to help out. While I was there, I went into her bedroom and tried on her panties. I got an erection, so I began to masturbate in her panties. Then she walked in. She became aroused, and we had sex for two hours. She gave me the panties to keep. Now, I swing by regularly to take care of her. She always makes me wear her panties while we have sex.
