Too funny, we used to joke that it would be a good way for me to learn, that size really does matter. For a long time the friends she had picked were never into it. But that changed, i didn't think i could do it, but she encouraged me. What really helped, was me being submissive to him, calling him Sir etc., and presenting a strap to him to use on my bare bottom. Next thing i knew i was getting my size does matter lesson. Geesh, that first time i was sore for about 10 days. Next time he visited i had the strap out for him.
