I still look back at that time almost in disbelief. We had neighbors in a town we lived in 15 years ago that we have stayed very close to even though we moved away three years ago because of a transfer in my company. Even though I work from my house about 80% of the time, they still wanted me to move to a more central location. Our old neighbor's had two children that we had know from the day of their birth. Alisa was the older daughter and was extremely nice but a very shy girl. She pursued athletics and was very good, but even us having known her for a long time she still was a girl of few words and preferred to stay out of the lime light. Her sister was equally nice but far more out going and of course teased her about being shy.
We found out that Alisa was going to go to college in our city and would be staying in the dorms on campus. The school campus was only 10 miles from us. She was young for her age group and turned 18 in September after starting school. We had her over for dinner a couple of times and she was genuinely excited about school but never told us too much that was going on. We were going on a trip and she offered to take care of our dog. The dog had a dog door and could go in and out on her own but would need food put out once a day. We gave her a key to the house and she helped us a few times. Over the first four months of school Alisa became like a live in daughter to us. She would come and go from the house regularly and used our house as a quiet place to get away from the craziness of school. Her dorm mate tended to party far more than she did.
My wife works from 7:30 to 5:00 and I tend to get up, do two hours of business paper work, and then run on the tread mill and lift weights. Then I would shower, go to work with email, business transactions etc. One day Alisa came over mid morning and I did not hear her come in. I showered and then walked out of my bedroom and into the family area stark naked only to find Alisa right there staring at me in all my glory. She had her Spanish book and asked what a word was before she glanced up. Her eyes went straight to my crotch and I froze. I fumbled that I needed to see it in the sentence and she got up and walked to me pointing at the sentence but her eyes kept glancing down at my cock. I quickly answered the question and said I better get dressed and she giggle and quietly said please don't on her account. She asked me another question but one I think she already knew. I answered it and then she asked a couple more. I started to get hard and decided I better go before I really got embarrassed.
I got dressed and when I came back out I apologized and she just giggled again and said no big deal that it was kind of fun. I swear I did not know how to react to her at that point. I noticed that after that she was coming over every Tuesday and Thursday morning as her classes did not start until noon. The next few days she usually found me working out and would talk to me. I would take a shower and she frequently talked to me from the family room about anything. She was more talkative than she really had ever been and about nothing really in particular. Then one Tuesday she asked me about a Spanish word again but came into the bedroom when I was naked and just acted normal asking me a couple of questions and trying to act like she was not staring at my cock even though it was easy to tell she was.
I got dressed and nothing was said about her seeing me. Thursday of that week she began coming into the bedroom and laying on the bed during my shower and looking at me as I got dressed. I knew I should not be doing this but for a 38 year old man it was stoking my libido. I convinced myself that this was harmless fun and this went on for a couple months. My wife knew Alisa would come over and the discussion came up about our work out equipment and my wife offered her access to use it any time she wanted.
A few days later Alisa showed up with a sports bag and worked out in the gym with me. She mostly did tread mill but also a few weights. She went to get a shower in the hall bathroom and a short time later I got in my shower in the bedroom. I came out not expecting her as I figured her shower would take much longer than mine, but she was standing with a big bath towel wrapped around her body and was drying her hair with a second. She just said that the work out was great and that she appreciated my wife and I letting her use the equipment. I grabbed my clothes and tossed them on the bed. As I began to dress she dropped the towel she was using on her head on the bed and then also took off the one covering her body and tossed it on the bed. I could not believe I was staring at Alisa's beautiful body. She has absolutely perfect small petite breasts with very pale pink areoles and the cutest stiff nipples. She has an absolutely muscle toned body with a flat stomach that slid right down into the blond curls of her pubic hair. She seemed to try to prolong her nakedness and I instantly got rock hard. It was a little embarrassing to try to get my pants on with a raging hard on. She then dressed and said she had to take off. She hung the towels in the hall bathroom to dry and took off. I hate to admit it but I masturbated two times to the memory of her body that day.
I knew this had crossed a line I did not expect. Sure enough though she continued to come over every Tuesday and Thursday and work out and then repeated being naked with me as we dressed and talked. She also would sit and brush her hair on the corner of the bed several times and spread her legs comfortably apart just exposing the soft inner labia of her vagina. I got comfortable having an erection in front of her and was not as embarrassed any more. One day she confessed that I was the first penis she had ever seen in real life. I asked her about her boyfriends and she said she never got that far. I asked if she was dating a guy and she said yes but not seriously. She was dressed before me and then blushed as she shyly asked if she could touch my penis as she was very curious about how it felt. Without waiting for an answer, she reached out and began to massage my cock with one hand and with her other hand on my testicles. She rolled my testicles in one hand and slowly stroked my penis up and down the entire length. She commented that is was hard but felt so soft. She also said it felt very warm. I could not help it but an orgasm was rapidly coming. I spread the towel out on the bed and turned so my cock was pointed at the towel. I told her to watch out and her hands went still, holding the shaft of my penis in her left hand and my testicles in her right hand.
