visit the first page you will find a passive guide there.
But as I understand it, you have a chance to get the urge to masturbate in battle, but never a skill for it. Some times it happens and the game will offer the option to do it in batle and sometimes not.
Get her nippels pinched a lot
Get her clit petted a lot
Watch inmates and guards jerk off (info on screen that they do jerk shoud suffice, you do not need to wait till they climax) a lot
Get toys attached to her clit
that should give you 4 different passives to increase your chance for masturbation urge mid combat.
