CB6000

Mistress ordered me to purchase a chastity device, a CB6000.  i found a place that sold it for a good price and ordered it.  it arrived about 10 days later.   i have tried to fit the tube over my puny worthless dick and it is way too tight, i don't fit into it.  i have done some reading and will try again when i have some privacy using lube and twisting it in.
