Yes, but she's not forgiven

You looked at Lily, still catching her breath. When you caught her eye, she looked back and nodded.

"Isabella," you started, "you seem to have made real progress with us. It seems like you have actually found it in yourself to show both of us kindness."

This was a tone Isabella was unfamiliar with. She looked at you with hope in her eyes.

Lily continued, "but it doesn't make up for the hell you put me through."

Isabella looked like she was going to throw up.

"None of us are going to make you cum. You can't use any of the toys here," she said firmly. Isabella whimpered.

Lily continued, "but you have been better at least. You are allowed to make yourself cum. Once."

Isabella didn't say thank you. She didn't ask when. She started.

Your life had been going well and recently, several women had masturbated while you watched. Every time, there had been something performative about it: you were watching, they knew you were watching, it was a bit of a show, and that was part of the fun.

This was something different.

Isabella was frantic. She slammed two fingers straight into her pussy, and twisted her body to get leverage to push and twist them inside herself. Her other hand started rubbing her clit like she was trying to light it on fire. She was panting and grunting like some kind of wild animal.

It took only seconds before her hand started making a wet slapping sound as her fingers pumped in and out of her cunt.

Soon, her grunting turned to moans, then gasps.

You and Lily watched Isabella for what seemed like a long time. There was more frenzied action than you had expected, or would have believed possible.

Lily quietly grumbled, "I only said she could cum once."

You responded, "I'm pretty sure this is still just one."

Isabella took the fingers out of her pussy and moved that hand to her breast. She grabbed it hard while her other hand continued to work her clit for all it was worth. Her gasps had turned to yells, interspersed with struggling for breath.

When her yells started to get hoarse, she finally calmed slightly. The floor below her was wet. One of her tits was red from the iron grip she had on it. Her pussy was swollen from the **** it had taken.

You and Lily looked on, amazed at what you had just watched.

Isabella finally caught her breath and remembered you were in the room. She looked a little embarrassed, but her sense of relief overshadowed it. She started to stand up, but had to lean against the wall for support.

She looked down at the puddle she left on the floor, "I'll clean that up," and headed to find a towel.

When she was gone, you looked at Lily. You both still had stunned looks on your faces.

You broke the silence, "that was..." you searched for a word that never came.

She agreed, "yeah, it sure was."

You looked toward the master bedroom, "do you want to...?"

"Yeah," she stood up and pulled you toward relief of her own.

Over the next few days, you were careful to "reward" Isabella by letting her masturbate just often enough to keep her coming back for more. Once a day, maybe twice if she was very creative in her efforts. Never predictably.

She quickly got over any hesitations about licking pussy. Emma and Madison were happy to have her get them off.

You learned that she really didn't like taking a facial, but she learned it had a high chance of success in getting her permission to masturbate. You could have made her like it, but after the stories you had heard, the sight of your cum splashing across her scowling face felt right.

Her tits felt great wrapped around your cock, but you always waited until Abby was out of the house before fucking her tits. You had made sure there was no jealousy among the girls but still, you didn't want to take away from Abby's "unique gift".
