After the past 2 encounters with our roommate, I was very nervous, scared, and excited to see where things were going to lead.
Spring turned into summer and things were fairly normal around the house. Diana gave me no indication that she wanted to continue our sexy late night fun. My wife was also acting as if nothing was amiss so I thought I would do the same. We all settled into a comfortable routine around the house. Occasionally, I would catch a glimpse of Diana in her panties or bra. One time she caught me looking up the loose leg of her shorts when she sat across the room from me. When I looked up at her face, she was looking me in the eye with a twinkle in hers. She winked and then got up and walked out of the room.
Lovemaking with my wife was good, if still infrequent and I found myself masturbating 2 or 3 times a week. The images that got me off the hardest were of Diana. I knew that things were going to have to change sooner or later, especially since Diana had set a target date to move out in 3 months.
In July, my wife made plans to spend a long weekend at the beach with her mother. They would leave on Friday and return on Monday. Since my job required me to work weekends, I wasn't going to be able to go. This had me kind of bummed out as I love the beach. It didn't occur to me that I would be alone with Diana for 3 whole nights. But apparently, it DID occur to Diana.
The Friday of her trip came and I left for work as usual. My wife and I said our goodbyes as she would be gone before I got home. I went through my workday with no unusual thoughts, and it wasn't until I was pulling into my driveway that I thought about Diana. She occasionally spent weekend nights with one friend or another so it was anyone's guess whether she would be home.
I walked into the house to find Diana cooking dinner. She was dressed normally and greeted me with a cheery "Hi', and a wave. I greeted her back and retired to the bathroom to shower and change.
Dinner was normal, with both of us engrossed in the food and watching TV. There was little to no conversation during dinner, and afterwards, I called my wife to see how her beach trip was going. While I was on the phone with her, she asked to say Hi to Diana as well. They chatted for a few minutes and then the phone was turned back over to me and Diana said good night and went to her room.
I talked with my wife for a few more minutes and after we hung up, I headed for my bedroom. As I passed the guest bathroom (the one Diana used) I heard her call out to me as ask me for some help. She opened the door wrapped in a towel and said the toilet was running. I went in and took off the lid. The flapper had gotten stuck and it only took me a couple seconds to fix it. Diana thanked me and I left the bathroom and went into the bedroom. I heard her shower start up and an image of Diana naked under the water popped into my head.
I felt my cock start to harden as I undressed and slipped into my bed. I lay there trying to relax as I heard the water shut off. There were several unidentifiable sounds and then I heard the bathroom door open and then her bedroom door open and close. With that, I attempted to relax enough to go to sleep.
I must have dozed off because the next thing I knew, Diana was standing next to the bed calling my name. I opened my eyes to see her standing there in a pair of boy short panties and nothing else. Her breasts stood proudly before my eyes and I remembered my wife saying that she had paid a lot of money for them.
