Master Pete, has been on the BDSM scene for some time now. In fact his first experience in the Master/Slave world was as a slave to a Master who's focus was on slave sucking and licking his cock and balls. This Master had very high expectations and just when slave thought it got it right Master would think of some other thing that slave was not doing right or some other thing that Master wished slave to do. For instance slave would gently take Master's cock into slaves mouth and with it's lips round the head Master will feel slaves tongue lick round the rim. This is something that slave's first Master trained slave to do. It may sound easy but is very hard to do well with out Master feeling slaves teeth!
Now as a Master I expect my slaves to learn how to do this and to do it well and if I feel teeth as a slave you can expect to be punished hard!!!.
