I have had this done to me several times and it is surprisingly erotic. The best was in Frankfurt when the dominatrix did a soft fantasy job on me by scrubbing me down with a hard massage brush in each hand before tormenting me with an Hitachi magic wand. Then she wanked me off and kept wanking after I had shot my load in gentle torture. Unfortunately, she did not drink my spunk or let me spunk over her tits. At the time it cost me Euros 500 but it was money well spent.
