bdsm / S & M, josei / toys #1

A boss matching with her subordinate on an anonymous "S & M" app.
Bondage, anal, double penetration, toys and so on.

I wouldn't classify it as "harem", since the main character is female.

Hardcore yandere mode on.

Bdsm (obviously), taming/training, sexslave, gangbang, sextoy, double penetration, humiliation.
It lives up to its title.
It can be both seinen and josei Imo, as the mc is female.

Average storyline, great sexscenes.

Grooming, forceful (but consensual), humiliation and so on

A lot of taming, bondage

HUGE trigger warning (childhood abuse from sibling). 'Psychological' tag should be added. Contains both a lot of consensual- and a lot of nonconsensual sex.
Imo some characters look waaaay younger than their supposed age - keep that in mind.

At first glance it looks like typical "master abuses servant" hooowever everything between them is consensual (a bit coercive like always with a naive fl).
