Tickle Slave Training (Patreon)

It's important for all tickle slaves to pair unbearable tickling with sexual arousal. So each subject endures hours of tickling on their most private and sensitive areas. The simple stroke of the feather along their lips and clit sends jolts of ticklish sensation coursing through their bodies but it's not enough to allow them to cum.  

Its also a (somewhat slow) but effective interrogation method.
