Let me start off by saying I love the stories, they get me so turned on.
Anyway, let me tell you the story of using my aunt's bra to jack off. I always shower after my aunt so I can get to use her bra which she leaves in the hamper. It's a lacey C cup underwired bra. I like to put it on and imagine I have her big round tits. Then I use the shower and turn it to a spray, so it makes mist. Then I start to stroke myself slowly thinking about my aunt. After a while I take off the bra and put my legs through the holes meant for your arms to go through. Then I use the shoulder straps and slide it up my crack. Now I have the thing tight and the cups are hanging near my dick. I stroke till I cum in her cups.
Sometimes I just use her panties to jack off with. You guys should try the bra technique if you understand it. Post me some comments if you like my story or want more.
