Instead of shaving my head they get me in chastity

Laughing, they start shaving my pussy.
I let them do it, fearing that if I try to move they'll cut me badly.
Once it's done they grab a big dildo. She inserts in my pussy, activating the vibrator mode.
I can't avoid moaning, excited at the vibrations it's sending to me, this is horrible, but i'm getting wet.
The dildo is connected to a strange belt they get around my crotch, covering whole my pussy and asshole.
Soon i'm feeling the orgasm building into me and when i'm sure i'll reach it it stops.
I look at them surprised, trying to understand what's going on, but soon it starts again making me lose concentration and moan again, ending again when I'm in the edge.
I look at her angry in frustration and she laughs at me.
"That's your new chastity belt. It'll make sure you're not used by anyone but me, (by what you should be thankful) and you won't reach an orgasm until I allow you to."
Then she frees you.
"Go to bed and rest. Tomorrow night we'll continue."
