I love women's undergarments. Sometimes I wear panties and find them exciting to do so. One pair of panties I bought years ago is a favorite. It is a sort of panty girdle and is very sexy. The top part is pretty high and goes almost to my navel. It is stretchy and satiny and feels great on my skin. The bottom part is stretchy and lacy and is cut like boy shorts. It has a shape in the back with elastic that pulls it into the crack between my butt cheeks.
I sometimes cut a hole in the front crotch area of the panties I wear so my cock and balls can hang out. That way they rub the inside of my pants and legs and get stimulated. Sometimes I do that and then wear another panty on top of that so they are rubbing something satiny. Today I went to put on this pair of panties and the thought of it got me hard. So I pulled my cock up and let the stretchy top part squeeze it against my groin area. Then I let my balls fall down through that hole. So they are isolated from my cock and rubbing on my rough jeans and the sexy lace part of the panties. It feels great and I'm sure I'll be getting off soon!
