See part 1 and 2 for details
MaryAnn's sister Debbie was going to be married in August and her lease ran out in April. Debbie had moved in with MaryAnn and she was even hotter than her sister. I think she was 24 or 26 at the time with a rocking body and large c cup breasts.
By now I was babysitting regularly and putting MaryAnn's daughter to bed really early. The sooner she got to sleep the sooner I would have some privacy to explore MaryAnn's things. When Debbie moved in she moved all of her stuff into the unfinished part of the basement. It was not long before my curiosity got the best of me. Debbie's stuff looked like a product of a hasty move and temporary living arrangements with her sister. It took a few searches, but I stumbled across a bag stuffed with lingerie. Jackpot, maybe a better word is jack off. I remember so many of the items all these years later. My two favorites were a satin rust colored panty and a white and baby blue silk camisole.
Once I made my discovery, my lust for MaryAnn and Debbie doubled. Once the kid was to bed I would grab some of MaryAnn's porn and head for the basement. At first I was careful, but as time passed I became less so. Often I would strip completely naked and grab one of the silky garments and proceed to work my rock hard cock and nipples. I often exploded on the old coal room floor. I became insatiable as time passed. Now I was using multiple panties to jerk with. Then it happened, I accidentally came in Debbie's little silk panties. I quickly hid them, back in the bag. Once I survived the incident with no repercussions I began to spray come at will into Debbie's lingerie collection. By the time her wedding rolled around I had literally come in every sexy thing she owned.
I had a front row seat at Debbie's wedding, as an altar boy. I was thinking the entire wedding how I had come in her satin lingerie and her maid of honor's panties. I still wonder what happened when she unpacked at her new home; but no one ever said a word. These young women sent me to a lifetime of panty jacking for which I will be eternally, but secretly thankful.
