Missing Satin Panties

I planned a Sunday afternoon picnic at the beach on Father's Day. We went to church as usual in the morning. Hubby preached a great sermon. We all brought a change of clothes. I always wear a dress or skirt with heels and pantyhose to church. That won't work at the beach. I also put an extra pair of clothes in my bag just in case we got wet at the beach and went out to dinner. That included an extra pair of teal satin panties that are hubby's favorite. I have caught his jacking off with them a few times. When we came into church, I placed my bag under the coat rack. It was zippered shut. After the service, I went to change my clothes for the beach and those panties were gone. I know they were in there. I looked all over my bedroom. There are just gone. So someone has my favorite panties. lol
