Stories of Tie Up Games

I've been looking for manga that contain bondage/TUG scenes recently, and I was wondering if anyone here has any suggestions?

Fairy tail has a lot of tie up scenes in it, even if very little of them involves gags.
There's also a manga called ''ratman'' in which the main character gets dragged off bound and gagged in the first two chapters.

For this, I can highly recommend Nana no Kaoru, which heavily features bondage, BDSM and related topics, but also an emotionally mature story with entertaining characters and developments.

Looks interesting. I’ll have to read it!
