The number of clit smacks she endures without a sound will be the number of seconds she will get with the vibrator, and a permission to cum.
The last time she could only manage 30 clit smacks before she could not contain a whimper. 30 seconds got her close, but wasn’t enough to let her cum.
Maybe this time she will endure enough smacks to finally get her orgasm.
It will be another week before she has a chance to try again.
