I was about twelve or thirteen and I spent a lot of time at my grandparent's apartment. My mother and I had lived with them when I was a baby while my father was in the Army so I kind of became their favorite grandchild.
I had become very curious about girdles (this was the early 60's) and had always seen my grandmothers on the chair in her bathroom. One night I finally got up the nerve to examine it and discovered the thrill of a lifetime. It had some stains in it and was very moist to my touch. I brought it up to my nose and up popped the first real hardon I can remember.
I became obsessed with smelling it each night after my grandmother took it off and got into her nightgown. I began jerking off to it at every chance I got. One night I told my grandmother that I was going to take a bath. I started the water running in the tub, sat on the toilet and began sniffing and stroking.
My grandmother must have assumed I was in the tub and came in to pee. Much to her surprise, there I was sitting on the toilet, sniffing her panty girdle and stroking away. Being an old fashioned woman, she screamed, pulled me off the toilet and turned me over her knees.
She began spanking my bare bottom and probably gave me the greatest orgasm of my life! I came all over her legs from the excitement. She became so upset, she put me in the tub and washed my little penis until I thought it was going to fall off.
She never said a word about it to me again. About three weeks after that incident, she came into the family room one Sunday morning as she was getting dressed for church. She had on a regular girdle with no bottom. She said she was having a hard time getting the stockings to clip to the back garter. She asked me to clip them on. Not only did I see her bare bottom, but when she turned round I saw my first bush!
Needless to say, you know where I headed after she left for mass!
