This is based on my real story, and I will tell it with as much detail as I can.
I’m a middle-aged man in my 40s, married, always been a bit chubby, but in my mid-30s I started taking better care of myself. I’m the father of two girls and have been married for 21 years now.
My mother-in-law is in her mid-60s, blonde, with honey-colored eyes, a bit chubby, but with great tits. I always saw her as a good mother-in-law; she has always supported me like a son, and we’ve never had any problems. She’s divorced and has had on-and-off relationships over the years.
I never saw her as anything other than my mother-in-law. She always has meals stored, she’s the classic grandma type, and I have rarely seen any part of her naked body.
I’m not medically trained, but I learned how to give injections, and because of that, I became the person who gives her injections. So you could say that seeing part of her butt from time to time was the only exposure I had to her body back then.
Like most men, I’m a handy guy. I repair things at home, so I do the same for her. Normally she would ask my wife, and we would go together so I could repair or maintain anything—furniture, A/C, whatever was needed.
I remember the first time things started changing was last summer. She asked me to install a bidet in the toilet, so I went alone that Sunday to do the quick install.
I had started taking Cialis not long before to help my sex life with my wife. It really helped and brought out sides of her I never thought she had—but that’s another story.
I went to install the bidet wearing a pair of gray basketball shorts. The night before, I had taken Cialis for my wife, and it was still having strong effects on me. Every slight thought or rub would bring my dick into a middle stage between hard and flaccid.
I arrived like normal, said hello with a kiss on the cheek, and we made some small talk. She still works as a teacher at a private school, so she always has good conversation. It’s a small house, with only one bathroom and an open living room/dining/kitchen layout. The bathroom opens directly to that space.
I started working on the toilet while she graded tests she had from the week. In the middle of the work, I started to harden up—definitely still under the effects of Cialis. I began thinking about flashing a bulge to her and how I could do it.
I finished installing the bidet very quickly, in under 10 minutes, but since she doesn’t know how complicated these things are, I started thinking about my options. I would occasionally bang the toilet to make her think I was still working on it. Since I was lying on the floor, I thought the best option was to ask her for something from the table and make sure I was semi-hard and visible so she wouldn’t miss it.
It worked like a charm. I didn’t have to do much to get hard; just thinking about her seeing it was enough. She passed me a screwdriver without mentioning anything—just said, “Here you go.” I couldn’t see her seeing it, but she definitely did. It was awesome and motivated me to be braver when I realized she didn’t mention it.
For about five more minutes, I was rock solid and a little ashamed of being that bold. I waited a bit and then started gathering my things.
I left it semi-hard and pulled my boxers aside so it could be seen very clearly. After gathering my tools and trash, I went to the living room, still semi-hard, showing my masculinity under a thin layer of cloth, and kept small talk going at the same time.
When I positioned myself in front of her, my dick was at her eye level so she wouldn’t miss it. I saw her make a quick jump and say a soft “oh, oh, oh,” pointing with her eyes at my dick. That made it instantly harder. A split-second later, she continued like nothing had happened—and so did I.
I continued showing it for about 5–10 minutes while we talked, and no one said a word after that.
I said goodbye, making sure she got one last look, and I left for my house extremely aroused and about to explode. As soon as I had a chance, I masturbated, thinking about what had happened.
I had a couple more visits after that, and the final one—so far—was when I flashed and masturbated in front of her.
