Transit Coffin Episode 3
 
PD upgrades Rain DeGrey to a bed, while keeping her hooded and bound. After observing Rain for some time, he gets the urge to test her cock sucking abilities. Her skills leave something to be desired, so Rain is locked to a post, by the neck, with a metal dildo stuck down her throat. Once she proves herself as a true cock sucker, she is taken to her final resting place: a metal coffin. There, she will be transformed, from bottom to top.
