I like this game very much, but it's too expensive. I'm hesitant to buy it. The main reason is that there is not much content for SM and bundled training. I hope there will be more content of this type, so I should make up my mind to buy it.

Sure~! We'll do anything. 
In the current update, we just added a player request feature: Invite Residents to your Room for sex. 

In the next patch, new resident: Da Thach and his horse 🥵 will be added, along with other residents such as Bardo with his hyper penis~ 
In future patch, many of our beloved side stories and events will be soon available, with iconic SM/roleplay/edging/rimming/foot/milking/caged... scenes.
