No sooner is the collar around your neck than she forces you to your knees. The master doesn't need to tell you what to do. Instinctively, you begin to kiss her pelvis, brushing your lips around her pubic hair. You can't remember if you've always loved the roughness of coarse red hair along your lips or if it's just the spell. But there's no time to dwell on such things.
Your mouth makes its way to your master's genitals. The soft flesh of her pussy gets you excited, but it's the taste that makes you wet. It's an odd sensation, completely different from being hard. The first instinct you have is to reach into your bikini and start playing with your newly formed clit. You long to have the master insert her fingers into you, or even, dream of dreams, lick you until you scream in ecstasy. These thoughts make you even hornier, and you continue to eat out the master's pussy with even more gusto.
You begin to hear the soft whimper of your sister as she continues to folder herself. The master's hands grip your blonde hair as she presses your head tighter against her pelvis. How badly you want someone, anyone to touch you, but your sister is occupied, and your master only cares for her own pleasure. You creep your hands over to your pink bikini bottom, and slide them inside, barely glazing over your clit. It drives you wild, and you're sure that your master feels it through your tongue as she comes.
"Well done slave," she says, holding your chin. The soft push of long red fingernails cues you to rise. "I think I'll call you Annabelle. It fits you better than whatever your name was before, I'm sure."
She gives you a deep kiss, pushing her tongue into your mouth. It lasts only a moment before she breaks away to give you another command.
"Your wonderful work has left me peckish. Make us something to eat, won't you Annabelle?"
