It was a couple years ago that Penny started attending night school to get her tech degree. I figured it was a great idea since I’d done it a few years previously and it helped me in the job market.
After a couple of semesters, I noticed that Penny was spending longer hours in the lab and getting home a little later than usual. It wasn’t a lot later, just an hour or so and I figured she was having some trouble in one of her programming classes. By the time she got home, I was usually fast asleep.
On one such night, I had just turned off the light from reading and was preparing to fall asleep when she arrived home. She must have figured I was sleeping because she came into our bedroom quietly and went into the bathroom without turning on the lights and was very quiet. Our bathroom off the master bedroom has a night light in it so I watched as she began to undress.
After removing her sweatshirt, I was instantly wide awake. She was missing something under that sweatshirt, namely, a bra. Penny never goes braless so I squinted to try to see better in the dim light. When her jeans came off, I noticed she wasn’t wearing panties either.
I didn’t want to confront her about it so I stayed quiet while she slipped quietly into bed and soon afterwards fell asleep. When her breathing became deep and I was sure she was sound asleep, I got up and went into the bathroom, closing the door quietly behind me and turned on the light.
Her jeans were in the clothes hamper so I took them out and did a quick examination after turning the top part inside out. There were just a few minute wet spots in the crotch. It wasn’t anything I’d see if I hadn’t been looking for them. I brought them to my face and inhaled deeply to see what they smelled like. It was a strange smell and one I know didn’t belong to Penny, or me.
I couldn’t understand why, but my cock was hard as a rock as I was doing this. Next, I went outside to the car and searched to see if I could find the missing panties and bra. The bra I found under her backpack on the front seat but I didn’t find any panties. On the floorboard of the passenger side was a hand towel. This I picked up and noticed how damp it was in certain places. Again, I inhaled and found the same scent I found in her jeans a little while earlier.
My first thought was to go back inside the house and confront her about everything. My second thought was focused on how hard my cock was and that I really needed some relief. I opted for the relief and after returning everything to where it was, made my way back inside and into my home office.
I turned on the computer and after going to one of my favorite porn sites, began to stroke my cock as I started to read some of the stories. Tonight I concentrated on stories about wives who were fucking around. While reading, I started visualizing Penny with another guy. The guy remained faceless in my fantasy however the cock he was fucking her with was very vivid. Soon, I started to buck my hips and had a new mess to clean up.
I decided not to confront Penny on this and instead, see what all I could find out. The intensity of my orgasm that night made me decide this was something to be explored.
Our sex life was still good so I had no complaints there. I just started making mental notes over the next couple weeks. Penny had class three nights a week but was only late on Thursday nights. It was also on Thursday nights that she was too tired to have sex when I asked. I also noticed she was doing a load of laundry on Friday mornings before she left for work. Other than that one night, I still had no proof to confirm my suspicions. When I’d look for her panties in the middle of the night, I could find none with any evidence of any activities. Finally, one Friday morning when she was about to start the wash, I told her to wait because I still had a shower to take before going to work and was running a bit behind. I volunteered to start the machine before I left. There was a hint of of reluctance in her voice but she finally said ok and left for work.
