Ok, these are forcedorgasm.thumblogger.com exclusive. They are suitable for a slave in D/S relationship.
1. Have a slave sit on the floor, spread her legs as wide as she can and order her to mastubate until she cums, never stopping for a second, and never losing the eye contact with you for a second. That's right, she got to stare right in your eyes, and that can make the humiliation very intense and make her cum sooner than you would think...
2. Make her squat. Have her drink some alcohol from a bottle. Before making each gulp, she must dip the neck of the bottle into her vagina. She must maintain eye contact with you all the time. Make her tell you about something trivial - what does she think of some of her colleagues, for example. Make it slow. Then she has made several dips, order her to stop drinking and to just move the bottle in and out of her hole, and to rub her clit with her other hand. Then she's ready to cum, make her beg for it (bring her on the verge several times for more fun). Then order her to cum.
3.Tie her up on the bed or on the floor. Gag her. Attach a vibrator between her thighs so she can't get rid of it. Turn it on. Then start to verbally humiliate her. Tell her she's a slut and needs to be punished, that she wants that that is happening, etc... She will be forced to listen to all this with a powerful vibrator inside her cunt! And to get pleasure at the same time as you degrade her verbally. And because of the gag, she can't talk back. Extension: read her diary to her aloud (the naughtier parts) or even her email - she will be forced to listen to personal letters from her friends read aloud to her while she is there naked, humiliated and with waves of pleasure shaking her body against her will!
