Not really, just 'scene a', 'scene b' and 'scene c' where we don't have to make it clear how much time is passing except that it could cover a couple of weeks and indicate that these are standard sessions he enjoys at their hands most days. Then by the time he gets a weekend invite to their home he's at a reasonably accomplished level of obedience and knows their style and such.<br/><br/>Though if you wanted to stretch out the initiation period and the breaking-in sessions that is fine by me.<br/><br/>I like the idea of a chastity device for him to wear home each day so he can't masturbate (and obviously can't have a GF). CBT stuff needs to be reasonably realistic to satisfy me. My husband dominates me 24/7 but even he likes to wear rings and weights and dividers sometimes and you can do a fair bit of damage if you cut off the blood circulation to any great degree for more than about 15 minutes at a time.<br/><br/>So stuff like cock-rings, cock-and-ball rings and ball-weights while fun and possible to wear 24/7 don't really force an erection. I'd like to hear from you though if you know of a safe way to enforce an erection because I'm not aware of one.<br/><br/>One thing we could do is have him wear a discreet ear-bud connected to a small encrypted wireless receiver that fits behind or inside his ear and the two teachers have mics and headsets by which they can verbally tease and abuse him all day long so as to keep him excited and hard, his manhood straining against whatever bondage he does have on. If it had sufficient range they could torture him at home this way too, or just send him instructions via texts or emails. The idea of a slave being forced to obey even when distant from the mistress is quite an exciting one.
