The events of this story took place when I was twenty years old, 6'-0", 185lbs, fit, with light brown hair and blue eyes.
Brenda had gotten my name from the instructor at the trade school I had taken my pre-apprentice carpentry course. She lived in a townhouse that backed onto a large overgrown green space and wanted a sunroom built to enclose her small concrete patio. Brenda was forty-eight, divorced and lived alone. Her body was nice enough that she looked pretty good in the bikini she always wore.
I began work in early summer and liked dressing in my light nylon shorts with the elastic waistband folded down (making my shorts shorter), no underwear, work boots, no shirt and a tool pouch. Brenda was often in the back on her lawn chair and being quite personable would be chatting while I worked, before going inside to make us lunch.
Brenda would usually give me a few minute warning so I would have time to wash up and sit down at the kitchen table out of the sun. I would take off my boots and socks so I would be sitting there with her in just my shorts. The outline of my circumsized cock would be clearly visible. I knew she was noticing and trying to remain aloof about the effect this was having on her so I did everything I could to expose myself to her like rolling the waistband further down on my shorts, hiking my shorts further up the crack of my ass. My cock would almost be hanging out of the bottom of my shorts and while walking it would swing beneath the thin nylon material.
On one day, in particular, I was doing some higher work where I needed to stand on scaffold planks I had laid on saw horses. Brenda was sitting on a short stool with her back up against the sunroom. I made sure my leg furthest from Brenda (my right leg) stepped up onto my scaffold first so my shaved smooth cock and balls could hang out of my shorts almost right in her face against my left leg still planted on the ground. I held that position while I pretended to look up to my handi-work and only stepped my left leg up when I could feel myself lengthening and thickening just prior to becoming hard. Once I stood upon the scaffold, my tool pouch covered me back up and I continued to work until my cock settled down. I would look for every opportunity to pull off this move throughout the morning before lunch coming down from the scaffold for nails or another piece of wood. I would feel myself get semi-hard knowing she was getting eyeful after eyeful of my cock. Brenda soon excused herself to go inside to begin making lunch and I came down to go around the side of the house to adjust my cock in private out of sight of the kitchen window.
A short time later Brenda came out and told me lunch was almost ready so I should come in a get cleaned up. She commented on how sweaty and covered in sawdust I was and suggested I had time for a quick rinse off in the upstairs shower if I wanted. I took off my tool pouch, boots, and socks and went inside. Brenda stopped what she was doing and followed behind me as I walked up the stairs. She was getting a good look at my butt cheeks hanging out of the hiked up shorts and my cock being just barely covered.
Brenda suggested she would rinse my shorts and they could dry over lunch. "Just wrap the towel around yourself and come down when you're ready", she said.
While standing behind the bathroom door naked I saw her reflection in the mirror looking right at me as I handed her my shorts.
