My best wank was about 30 years ago. I had a thing for my Mother in Law. She was so horny and flirted with me all the time. Her and my father in law went away on holiday and asked me to look after the house by dropping in every now and then.
I went to check on the house and went into their bedroom. I decided to look through the drawers and found some stunning Knickers and bras. A lacy red bra took my fancy and I put it over my cock, which was absolutely rock hard, and I stroked until I shot the biggest load I'd shot for ages.
I still wank to that now.
