My wife and I live in a upper middle class suburban neighborhood. The house next door was recently sold and the new occupants are a very good looking couple, Dan and Carol, about the same age as us. My wife has a position with a large company that requires her to travel periodically to train other divisions of her company on new software. Her trips usually last 3-5 days. Dan is a travelling salesman who is away from home at least 60%-70% of the time during the week.
About 3 months ago my wife was away on one of her training trips when I received a phone call from Carol. She said Dan was away on business and asked if I could lend her a hand putting up a wallpaper border as she didn't feel safe up on her ladder. I walked next door knocked on the door when Carol told me to come in. She said she was in the kitchen. I went to the kitchen to find her working with her wallpaper tools. She did not have a very sturdy stepladder and I could see why she wanted some support while up on it. She brushed some paste on a section of the border and started up the ladder. She then asked me to support her legs so she wouldn't fall off the ladder.
Carol was wearing cut-off jeans shorts. When I grabbed onto her legs to give her support I then noticed that she wasn't wearing any underwear. My cock grew hard instantly. I am fairly well endowed and couldn't help but bulge in my own shorts. Carol moved around on the ladder changing her position and at the same time changing my view of her shaven pussy. My swollen cock was feeling strangled in my shorts and It was beginning to feel painful. I knew I had to release my cock from its confines very soon.
After Carol finished hanging the latest section of the border and stepped down off the ladder I asked if I could use her bathroom. She looked down at my bulge and said of course. I went into the bathroom and took off my shorts and undershorts. I put my shorts on and folded my undershorts and put them in my back pocket. I felt much less constrained and felt that I could now continue helping Carol.
I went back to the kitchen and Carol was ready with the next section of border. This time when she went up on the ladder she had to bend to reach the area she was papering giving me a startling view of her ass. My cock was hard again but felt much less constrained without my undershorts. Carol was giving me a show that was driving me crazy and I could tell she knew it by her movements while she was on the ladder with me holding on to her ever spreading legs. I could also see from the glistening condition of her cunt that she was also getting turned on by this scene.
The next time she came down from the ladder she asked me if I would like some ice tea. I said I would love some and we sat down at the dining room table to drink some. Carol was walking back to the table when she looked down at my lap, gasped, and almost dropped the glasses she was carrying. I looked down to see what caused the sudden problem and noticed that the engorged head of my cock was protruding from the bottom of my shorts and in plain view.
I apologized while trying to adjust my shorts to cover my cock. We both started laughing and had a good time discussing the situation. I told her that she had a magnificent looking "bottom" which, since she chose to display it to me, was causing my hard-on. I told her about the real reason for my trip to the bathroom that caused my embarrassing situation at the table moments ago. Carol said that based upon the small amount that she was able to see she thought that I had a remarkable penis. She then said to me that she felt that she had done enough wallpapering for tonight and felt tired and sleepy. I told her that I would be most happy to help her finish the kitchen whenever she was ready. Carol thanked me and showed me to the door.
Before letting me out she planted a kiss on my lips that made me feel weak in the knees. Carol was quite a seductress and she was being extremely successful in seducing me. I walked home got undressed and got into bed. I realized I still had a raging hard-on and couldn't keep my mind off Carol. I played with myself and came in large spurts. I expected my cock to soften but it remained hard as a rock.
After about a half-hour of "twisting & turning" restlessly in bed the phone rang. I answered the phone and it was Carol. She told me that she couldn't sleep and was thinking about my cock and me. She told me that she had already come twice just from the thoughts and wanted to see how I was doing. I told her that my cock would not soften even after shooting my wad. I told her that I couldn't get her out of my mind. She told me she felt the same about me. She asked me to begin playing with my cock and fantasize that it was her playing with it. She told me she was fingering her cunt and clit and fantasizing it was my hand playing with her. I told her that I was about to cum again which made her climax screaming into the phone that made me lose my load.
Fortunately I had brought a towel to bed realizing my state. I then told her that I wanted to make love to her and she said that I should keep that thought in my head. I told her that if I did that I would walk around with a perpetual erection. She laughed and said "so what since she was planning to walk around with a perpetually wet cunt." With that statement my cock began hardening again and I told Carol about my condition and said that I have to get some sleep now as I had an early meeting tomorrow morning.
