My name is Karan and I am a 34-year-old married man with a happy family life. I am average guy around 6 feet tall, thin and about 6" dick (to be very frank, I never measured it...never felt the need). I am sexually active man but haven't had any affair post marriage, as I never wanted to disturb our happy life. This incident happened in a gradual manner not the wham-bam-thankyou-Mam way, as it happens in most of the stories.
We currently live in Mumbai and this happened when my wife's sister, Nita, came to stay with us. She is around 26, unmarried, wheatish complexion, nice figure, good solid boobs and a perfect ass. (It sill amazes me how some authors get the size of boobs just by looking! I never bought a bra myself so have no idea what 36 A B C D are). She has taken up a job in Mumbai and was staying with us and also looking for a small apartment.
Since the day she arrived, I used to feel extremely attracted towards her and really wanted to get close to her, feel her and ultimately fuck her. But I was very careful so that my wife must not get any idea about my intentions. I used to talk to Nita casually and never gave her any impression of what I have in mind. When no one is around and she is looking elsewhere, I used to ogle her boobs and ass and used to wish how I can hug her and press her boobs and kiss her full lips. I also started masturbating thinking about her lovely body hugging me, and her rosy lips around my dick, giving me a blowjob. I have this extremely erotic fantasy of naked women hugging me from behind, their hands roaming all over my chest, pinching my nipples and playing with my dick.
After some time, Nita shifted to her one bedroom apartment but still used to visit us often. I was cursing my luck that I couldn't do anything. But luck was in my favor and my patience paid off. After joining her job, for commuting she decided to buy a scooter and with that came an opportunity to teach her riding scooter. My wife, thinking I am a gentleman, asked me to teach her riding with our scooter and I was sure that this would definitely lead to some fun.
It was decided that I would teach her driving for few days early in the morning to avoid traffic. On the first day, I reached her house at 5.30 AM early morning. Just the thought of me sitting behind her and holding her hand while teaching her was giving me a hard on. Nita was waiting for me in a loose casual T-Shirt/skirt at the gate and I offered her my scooter to drive. She was very nervous and I was also taking things slowly. I wanted to gauge first if she is also interested in me or not. I told her to sit in front and I sat behind with my hands holding the handle from outside her arms. My front was totally glued to her back, with my face on her shoulders. I was really feeling very horny. Holding her hands over accelerator and clutch was really pleasant. She was a bit nervous on my touch but cooperating, as it was the only way to teach. First day I didn't proceed further and we took few rounds on empty roads. After the lessons, I went to her apartment for tea before leaving.
Next day I decided to be a bit bolder. I told her that it is difficult to hold her hand from outside and I have to hold handle from her underside. She lifted her arms and I glided my hands towards handle touching sides of her breasts. That was my first touch of her breasts and they were soft from sides and I was feeling very nice (No bra, I wonder why!). I was purposely rubbing my arms with her side breasts and she seems to be enjoying. In between I pulled my hands and asked her to drive with only her hands on handle. She was picking up driving nicely and I casually put my hands on her waist for support. When she didn't say anything I extended my palm to rest on her stomach and pressed it slightly. During the lesson, I kept both my hands on her stomach and pressed it several time. Intermittently I used to put my hands on handle along with her and take pleasure of her boobs. Once I brushed her thighs as well. From over the thin fabric of her skirt, her thighs were soft and smooth.
Third day, I was a bit more adventurous and from very start, I held her waist and slowly messaged her it with vertical movement from her side breasts to thighs. I had a hunch that she will let me play with her body some day. I held her hand several time, pressed her thighs, rubbed her belly and once accidentally pushed my hands high enough to touch underside of her breasts from front. It was extremely exciting and my dick was fully erect and I was sure that Nita might be feeling it at her back. We were literally glued together and once I purposely brushed my lips over her bare shoulder. I was feeling the heat coming out from her and during our talks; she once said, "Karan, you are very naughty!" But she never mentioned anything to my wife and it was an encouraging sign.
