I revealed my penis to my stepmother while she was doing laundry and here's what ensued

I had a naughty idea when I saw my stepmother doing laundry in the backyard. I decided to show her my cock through the window, just for a laugh. To my surprise, she caught a glimpse of it and her reaction was priceless. She was so shocked and excited at the same time. It was the perfect opportunity for some solo fun. I hurried to the backyard, where she was hanging up clothes. She teased me, asking if I wanted to play a game. I couldn't resist. We went inside and she started stroking my hard dick. The old MIL was a pro at giving handjobs. It was an unforgettable experience. The house was filled with lustful moans as she brought me to the edge. It was a wild ride, and I could hardly hold back my cum. It was a perfect end to a naughty prank.
