A playground for perverts, where there's no place for NTR or any related BS. An abode of couples or maybe even love triangles who forget restraint and do the nasty deeds and then live happily ever after.
Don't you want to join these degenerates? Don't you want to forget the world and look at their reactions as they flirt and f*ck with each other?
Don't deny, embrace the fantasy and who knows, you'll paint your room white by the time you "finish". >:)
