"There, girls. No need too fight. There’s plenty for both of you."
Suppose you have a slave and you enjoy cumming on her face. Suppose further that she finds this distasteful and has been careless enough to let you see her disgust. Perhaps she’s even turned her face away, or closed her mouth, or displeased you with similar displays.
For a time, you might inform her that her slave duties now include catching as much of your ejaculate as possible in her mouth. This is difficult even with the best will in the world, and she’s been demonstrably reluctant. So, at first she’s not very good at it.
Thus is born a training exercise! For motivation, control her food for awhile. Tell her that she gets one meal a day, and that it won’t be large. Let her go 24 hours without feeding, then place her in the situation illustrated by the .gif. It’s OK to make the liquid calorie rich and tasty (sweetened cream would do nicely) because she won’t catch nearly enough of it to satisfy her hunger. That’s OK, you tell her; she’ll do better tomorrow. For now, back in the kennel!
Within a week, she won’t be missing a drop.
