Pleasure and pain until Naughty Masochist squirts - chained to a table

in this scene, Master Mephisto subdues his submissive very harshly. Puts so many clothespins on her tits and torso, taking her to the limit. While she is suffering, place a Hitachi on her pussy and control her pleasure without letting her reach the orgasm. He slaps her pussy with a ruler, and she struggles between pleasure and pain. Finally, Master Mephisto makes him pain slut to squirt, soaking all the entire table where she is chained.
