Anyway, one of the older men on the yard introduced me to the joys of chaining. Basically you push as much chain as you can up your pussy and keep it there, while you go about your day. I works wonders for your muscle control and even more for your orgasms. He worked on it for days trying to get more and more links up me. When I was full, he would then slowly put his hard cock up me and fuck me till he came. He would then leave and invite the next worker up to my cabin.
