While I was growing up, quite a bit of people lived in my house. It was my family, grandmother, uncle, and aunt. My aunt was a beautiful woman about 5'8 and was in her 20's. I was very young at the time yet I would still get erections mainly because of her at this age. She worked in an office so she usually had to dress professionally.
One thing she would wear alot was pantyhose, usually with a short skirt. I'm not into pantyhose but this was a turn on since she had great legs. Several times, I caught her taking off her pantyhose. This was very sexy since she would hike up her skirt, and pull them off. Other times, she would walk around the house in a short dress shirt and pantyhose underneath and iron her skirt. This usually caused me to go to my room or bathroom and masturbate because i was so turned on. She would do other sexy things but the funny thing was she would act like nothing was happening, like she didnt care even though she was a classy woman. One time she just came back from bike riding with friends. She was wearing tight black bike shorts. I saw her talking to my grandmother about something and then I saw her pull the waistband of her shorts from the front with her hand and stick her other hand in and scratch herself since she had an itch. She didnt scratch her private parts. Just a couple of inches above it. Once again acting like nothing at all. Another time, my grandmother and I were in her room watching the news. I was washing my hands after using the restroom and she came in to pee. There was a huge story on the news so she left the door open to hear it. Then she stood up after a critical part in the news to see it. She was wearing a grey sweater, with her sweatpants around her knees and tan pantyhose underneath. I got such a hard on with her just standing there pulling her sweater over her crotch to cover her private parts and acting as if nothing was happening. I couldnt help it so I went into my room, got under the covers, and exploded a huge load. I always bring a kleenex to clean up the mess when I do this. She moved out of the house after she got married so I dont see her much. However, I always look fondly at those memories in my masturbatory sessions.
