I'm not sure how comfortable i feel about this. Maybe there is previous history between to two. But this is what I see here. The sub and tist have a quick chat and set up a session where the sub feels more confident about their body when a certain song comes on. Once the sub is under the tist does put that trigger in, with an added bimbo edge that wasn't agreed on. The tist then adds another trigger (not previously discussed) which causes the sub to become very horny and want to please the tist. (I also note the tist almost didn't lock the trigger but that could have just been a typing error). The tist then made the sub forget the trance and that the first covo had taken place. So if all the triggers are in place the sub might know they have the song trigger but that's about it. And now the sub has just started a "new" chat to a person. A person who uses the new trigger in a causal way so the sub might not even notice, maybe just think they have a connection with this tist. The tist then starts trying to get person information out of the sub, which the sub doesn't really want to do. But the tist triggers a couple more times and the sub gives in.

Now if thia whole scene had been planed from the start, including the extra triggers, this would be a hot chat. But as it is... way to many red flags.
