today we will see the mistress raging in a milking of her slave.
a foot pump will be used: the slave's cock is stuck under a cockbox and will be drained to the last drop.
the infernal boot will crush the pump until multiple ejaculations are obtained.
of course the clothing is the right one for the occasion: to protect itself, it will wear a latex suit and rubber boots. she would never want to get dirty with cum, so much cum.
