"seidorei keikaku" is an SM channel run by Maria and her partner.

Her male partner is Maria’s slave😅
These are training-type videos, and the main ones are videos in which men are tortured with full-body restraints and suffocation.

Maria has an attractive body with powerful buttocks and thighs, and she also has a cool aura that makes you feel the dignity of her master.

Maria's specialty training menu is ``face compression with a big butt''.
I am forced to serve pussy and anus in facesitting position.
A man who is suffering and Maria who seems to be having fun.
The contrast creates an indescribable eroticism.

In addition, there is some rather hard play such as trampling with heels, gold bullshit, and drinking urine, but generally Maria is a kind master.
There are also plenty of videos that you can enjoy normally, such as hand jobs while verbal abuse and breastfeeding play.
Of course, there are many scenes where Maria is erotically disturbed.
