Well my mind was wandering at work today as usual when I started thinking about some thing I read from Sparrow about alternative stimulation. Then I had a (what might be good ) idea. I happen to see some large river rocks in a garden and thought that would really hurt (but not damage to much) if you put them in boiling water for a while long enough to get really hot then carefully laid them on your favorite sub's body in some not too delicate places. I'm thinking the weight plus heat would create some interesting sensations. so what do you think? If this is old news and already been done I'm sorry but I ve never heard of it before.
