They all get to cum eventually.

Lori was suffering from the shocks.
Lori was being pleasured by the women.

She cried out in orgasm!

Donna was not a cruel Mistress.

...okay, but not in this one regard, at least.
She put a vibrator in place for Dana to cum.

She soon did, even with her mouth full.

Jenni was next.

She's a screamer.
Donna likes that.
She listens to her orgasmic cries as the vibrator does its thing.

Jade didn't impress Donna- at least not yet.

As such, Lori was given another orgasm first.

Finally, Jade got her turn, making a lovely cry of joy for Donna...

Donna turned off the electricity.

Her bitches thanked her...eventually.

"Don't worry- I'm not done with you all yet," she says.

She takes the 4 ladies away one at a time, building up suspense.
