I started to wear my Aunties ( My Mum's sister ) open bottom girdles, knickers and nylons in the summer of 1965, it was unbelievable and I couldn't help but wank and cum over everything, felt guilty but very happy.
My first experience of wanking and cumming in gorgeous satin knickers was in the mid 60s, when I wore my Aunties knickers when she was at work, it was wonderful seeing my cum ooze through the material and thinking about her wearing them.
I have done this a few times with another guy wearing garters, stockings and nylon panties. At first it was just feeling then licking panty cock, kissing and in a nylon 69. Its fantastic
