That string is a bit brutal. I had a multi gym in my cellar. I used to have sex with an old girl neighbour who I discovered liked to be restrained. Not having the money to buy bondage harnesses and cuffs and there being almost no Internet in 1992 to order it from I made my own. Visited a car scrap yard and stripped the seat belts out of a car and got the sewing machine out. My neighbour was thrilled with my work and enjoyed many happy hours being punished and pleasured. I could wear down 4 AAA batteries in a night tormenting her cunt with a rabbit type toy and vibrating egg.
