Abby has some tips

For the rest of the day, you tried to be a good person. You tried to not take pleasure in tormenting Isabella. You failed.

At the end of the day, you happily crawled into bed with Emma and Lily.

When you woke up, Abby was laying beside you and you started your day by fucking her tits. It wasn't until she was wiping your load off her chest that you even remembered Isabella existed.

When you exited the bedroom and first saw Isabella, she was looking rough. The fire in her eyes had been replaced with sadness. Her shoulders were hunched with tension.

You walked by her and made eye contact. She asked sadly, already knowing the answer, "please... will you let me...?"

You actually felt bad for her. Even in this state, she was hot. You sighed, hoped Lily would forgive you, and decided to extend an offer. "How about this... I'll let you give me a handjob. If you're any good at it, we'll let you cum."

She practically lunged at your cock.

You had heard the phrase "beat it like a rented mule" before, but now it made sense. Isabella definitely did not intend on letting this opportunity pass.

She worked your cock for everything she was worth, pounding away, making sure you were going to cum fast and hard. You looked down to see a look of determination on her face, and her tits giggling in time with her feverish strokes.

It wasn't physically possible to resist for long. When you started to cum, she didn't even slow down. She sprayed your cum on her arm, some on her tits, but mostly over her shoulder.

When she finally stopped abusing your dick, it took you a minute to get your thoughts together.

Just as you looked down to see Isabella panting with a smug look on her face, you heard laughter and an unexpected voice behind you, "What!? On the floor!?" Abby apparently took issue with Isabella's technique, "you didn't aim it at your tits or anything! Was that the first time you gave a handjob or something?"

Isabella was glaring at her, both angry and confused over the reaction, but she laughed and continued, "I mean... on the floor? Have you even been watching us?" She laughed again and wandered out of the room.

Isabella looked like she was about to strangle Abby, but you intervened, "I think she's right. It was obvious that you were just jerking me off so I'd let you cum. There was no joy in it. We expect better in this house."

Isabella stared at you, shocked at your evaluation of her performance. You continued, "I think you can find a towel in the cupboard to clean that up," you waved at the cum she had sprayed on the floor, "and you can think more about how to show kindness to others, and I think you'll give some more thought to how you might be rewarded if you do."

She looked at you and gulped like a fish a few times. She clearly had a lot to say, but either couldn't or wouldn't let the words come out. She eventually gave up and slunk out of the room, returning with a towel and cleaning your jizz off the floor.

You went to find Abby. She anticipated your question, "Lily's not the only one she was mean to, you know."

You didn't even want to ask, but could see the sadness in Abby's eyes. You thought about this for a moment, and replied, "Abby, what can I do right now that would make you happiest?"

Abby laid down on the bed, and you laid beside her. You spent the next hour holding Abby close to you, feeling her tits, and whispering the dirtiest things you could think of in her ear while she played with her pussy. You told her everything you wanted to do with her, every position you wanted to fuck her in, every detail of how you wanted to make her cum. She got herself off over and over again.

When she was finally completely satisfied, she demonstrated what she felt was proper handjob technique. When she was done, she smiled to herself as she wiped your cum off her face.
