Embarrassing and/or Painful Ways to Make Your slave Masturbate II

Courtesy taken@subhuman.org

1. The slave masturbates kneeling before one of Mistress's used menstrual pads, and climaxes upon it. The slave then wears the pad in his own underwear/panties for a period of time specified by Mistress.
2. The slave is only allowed to masturbate with a thumb and one finger (this can be incredibly frustrating for some men...).
3. The slave masturbates while Mistress plays Her favorite song from a CD or cassette, and must climax (optional: and eat his cum) before the end of the track. This is especially fun as the finale for a strip/dance performance by the slave! (Variation: Mistress selects a CD with children's songs... much more difficult--and humiliating--to masturbate to climax while listening to Barney! This variation can be used as a punishment for not being able to cum before the end of a "real" song.)
4. A variation on cumming on a plate of food before eating it: Mistress has slave carry a pill bottle/film container/small squeeze bottle with him when they dine out. Mistress makes slave go into the public restroom (slave hopes the restroom has a stall with a door!) and cum into the pill bottle. The slave must return when he's done and present the bottle to Mistress so that She may evidence his obedience. At Her discretion, She may open the bottle (which looks innocent enough to outsiders) and spoon the contents onto Her slave's food before he consumes it.
5. Mistress requires the slave to masturbate (while being as vocal as possible) while making an audio recording (if the slave is shy, Mistress might suggest phrases, especially near his climax, such as "O Mistress, I'm cumming for you..."). Mistress may then play back the recording whenever She wishes to humiliate Her slave.
