Maid in Heaven SuperS

Although different in many aspects, both series share a common theme in consensual BDSM, not something I have seen much of, especially compared to the nonconsensual kind. Other than that, however, they are rather different; while Maid in Heaven shows us a considerably wide variety of BDSM practices from the girl's point of view, Gekka Bijin foregoes most of these, sometimes grazing the surface, and instead presents us with a large treat of bondage (in all kinds of poses) sprinkled with a bit of plot, several girls and a yuri scene as the dessert. As an added bonus, they are both good ol' uncensored hentai. 

Both seris feature maids who serves a master who abuses them in public places and with toys etc.
