It wasn’t the best holster for the up coming job, but I still had a few days to pick up a new one.When I arrived at the range, I waited for Mary Bet... to arrive before I called the range office to release the gate lock. Once we were inside I relocked the gate, then showed Mary Beth to the first firing station. It was the spot where she should begin her lessons.The station was sitting on the ten meter line. That was about 33 feet on a real tape measure. It was also about as long as the longest. "Were you going to leave without saying goodnight," she asked coyly."N-no," I sputtered, "I thought you had left. You're table was empty and I..." I sent the girls home without me," she said. "They insisted that we all drive home together, but I told them that I felt like living dangerously." What do you mean? Do I look dangerous," I asked."I don't know," she said, "are you?"I didn't tell her at the time, but I had a hard-on that extended easily beyond my knees and toward my ankles! She exuded. I wanted focus on the kids and only have a few distractions that afternoon. Just by the smirk she gave me I could tell that she knew the distractions I was talking about were Candice and Jenny. With a coy look she sexily said I will make sure that all of you are distracted by me today too. We went upstairs and got into our swim clothes and she went into the bathroom again and just said for me to go get the kids and meet me at the pool. The kids came down stairs and we headed out to the pool.. Still a little groogy from the night before but excited and hard all I could do was nod.Next thing I knew my Mother-In-Law was astride me and had my now hard cock right inside her pussy! She started grinding me back and forth, making me ever so harder inside her.I said to her "this is wrong, but you feel so good and tight!"Caroline said "Donna and Bill are away to work now, so you're mine now. I know am bigger and an SSBBW but am top what you going to do?".I said "well roll you off me".To which.
