The Management of Ripe Ass Ejaculation in a Fair Woman's Watch

No matter how rough the prisoners are, there is a reputation for female guards who turn into model prisoners. Yumi, who was a female guard with a large and ripe buttocks, used secret prisoner management techniques to cut out the violence and put it into work of imprisonment and turned it into a model prisoner. The method is to feed the jealous buttocks on the crotch of the prisoners and give pardon for ejaculation only to those who become obedient. Prisoners take their sentence seriously, dream of the supreme ejaculation that is a reward, and just continue to die seriously.
