This is another true story.
My grandmother was the only living relative on my fathers side and he was an only son. She was in her 90's and was beginning to struggle with the ability to take care of herself. It got to the point that my father was staying with her during the week and my sister and I would rotate weekends. Being married this became a bit of getaway for me and my next opportunity to explore my exhibitionist side.
During the day my grandmother would take her naps and in between preparing meals and doing yard work I would find some time to myself. One hot summer day I was out trimming some bushes along the side of the house closest to her neighbor. The neighbors house was only footsteps away from the side of her house so it was pretty easy to see what was going on in both yards.
With the sweat dripping down my face and onto my tanned bare chest I happened to glance over to see the neighbor lady smiling with a wave. I politely waved back not thinking too much of it and carried on with my chores. She continued her yard work and I continued mine but she caught my attention as she was bending over clearing the weeds from her raised bed garden. Now to be clear, she wasn't the most beautiful woman but she did have a well taken care of 40ish petite body. We continued on with our work with not much more excitement other than the occasional smile.
The next day I thought I would try to take this a little further. Her master bedroom window overlooked the front porch of my grandmother's house which gave me an idea. With my grandmother taking her late morning nap I thought I would try to get a little sun on the front porch but within shouting distance if she needed me. As I sat down on the first step I noticed the neighbors' blinds and window open and she was folding clothes. I slowly peeled off my shirt then unbuttoned my shorts slipping them down to my feet exposing my tight boxer brief style underwear which accentuated my cock. I wanted so badly to expose myself but wasn't sure what her reaction would be so I refrained and lay down on the porch in a way so she could see me from my cock up. As I lay in the sun I would try to inadvertently take peeks to see if she was watching and she was. I was getting so horny at this point that my cock was leaking precum which seeped through my underwear and glistened in the sun just for her.
