Master ordered slave to train its nipples and cunt with clamps and electricity and record progress. Slave at first have to get used to painful clamps. And then add electricity. Very painful. - vitgun123
My nipples love it when you get a little rough...but since I'm alone I have to do it myself. I can cum from just this, but it feels even better if I have someone filling up my holes from the back - MizzMi
