Yes, enough for now.

"Enough Sabrina," you say as you move over and pull Sabrina's hand away, taking the hitachi off Emma's far too over-stimulated pussy. Emma groans in relief as you do so, all she can manage to do at the moment, her mind still jumbled from the pain and pleasure.

Sabrina looks at you, a mix of surprise and anger in her eyes at being forced to stop. She's clearly ready to continue her sister's suffering but you want the tension to continue building up, and you don't want Sabrina to ruin Emma's pussy and desensitize it.

"Sabrina, you've won and Emma has already now earned another punishment," you say, a bit wary of the look in Sabrina's eyes, "I think we all need to recharge a bit and then you, me and Katherine will discuss what punishment must be doled out to Emma for finishing in last."

Sabrina's look softens and she nods in obedience. You glance down and notice streaks of juice coming out of her pussy and down her thighs. She's turned on - very turned on, and her free hand is twirling slowly on her thigh. She doesn't seem to know it but she's horny as fuck from forcing her sister to take two brutal orgasms.
