Yeah, she has more to learn

When the bedroom door closed, Lily threw her arms around you, "oh my god, that was awesome! Her shirt! You ruined her stupid fucking shirt!"

"I feel a little bad, but goddamn that was fun. Well, should we send Isabella on her way?"

"What no! I'm not done with her yet!"

You laughed, "I thought you didn't want her here."

"She put me through years of hell! Watching us fuck isn't punishment. Emma watches us all the time! We're not punishing Emma!"

You had no counter-argument to that, but did take a split second to reminisce about all the times you fucked Lily while Emma watched.

You and Lily returned to the living room. Emma, Madison, and Abby were still playing. Abby had moved to the floor and was licking Madison's pussy while Emma played with her tits. Madison was being her usual vocal self, and the room was full of her moaning.

Isabella was staring at them, unable to fully process what she had seen, and was still seeing. She had obviously tried to straighten out her shirt in the hopes of putting it on, but given up and put it back on her lap. It had absorbed too many bodily fluids.

"We need to talk," you announced to her, "I understand you have been", you searched for the word, "unkind to Lily in the past. That was wrong, and I think you need to be made to understand that."

She looked angry said only, "I...". She wasn't about to admit fault, but couldn't disagree with you.

"I hear you have spent a lot of time making people unhappy. In this house, we have learned, well... Abby? What do we do here?"

Abby pulled back from Madison's pussy, turned to Isabella, revealing a soaked face, and answered, "we make each other happy!" She immediately dove back into Madison. Isabella stared at her.

"Isabella, listen carefully." You braced yourself for what you knew was about to come, "I think you are going to stay and watch what we do here. I think you are going to try to understand how much better it is than the shitty way you have been living your life."

She looked at you with anger in her eyes. A sharp pain was shooting across your head. You looked at Lily, took a deep breath, and back to Isabella. "I think you are going to be turned on watching us, but you aren't going to be able to do anything about it. None of us is going to make you cum," she scoffed at the thought, "and I think you won't be able to do anything to make yourself cum either, not unless we allow it."

She looked at you with a mixture of anger and confusion. She turned to the girls, "I have to watch them?"

"I think you are going to show your new housemates some respect! And yes, you are going to watch everything that we do around here, and I think you're going to like it."

Your head throbbed with pain, but weren't about to show it. You ignored her, took Lily by the hand, and joined the other girls. You and Lily climbed between Emma's legs and took turns tasting her.

Getting Emma off made you feel better. You felt even better when you switched positions and Emma sucked your cock while you rubbed Lily's pussy. When you came in Emma's mouth, she pulled Lily toward her, looked at Isabella to make sure she was paying attention, and shared your load in a sloppy wet kiss.

Isabella was obviously uncomfortable, but her short angry breaths had been replaced by deeper, slower breathing. You watched her chest rise and fall. She had been watching all of you very closely.

You saw a problem. "Isabella, you look uncomfortable. I think you need to fit in better around here. Take your bra off."

A range of emotions flashed across her face: confusion, annoyance, embarrassment. She settled on resignation, and slowly reached back and let her bra fall in front of her.

Holy shit. You couldn't react. You couldn't let Lily or the others see you thinking anything positive about Isabella. But holy shit.

You decided to lean into it, "your personality might be a problem, but damn," you took a shameless look at her tits, "at least you have that going for you."

She practically snarled at you.

"I think you're going to enjoy the show here," you asserted, "in fact, I think you already are, aren't you?"

She didn't want to admit it, but she couldn't lie to you either. She managed to grumble, "Emma's hot."

That was good enough for you.

You looked at Lily. The look on her face made it clear she hadn't changed her opinion about Isabella. You took her by the hand and started to lead her out to the patio.

You looked back at Isabella, "I'm going to go get some sun and lick Lily's pussy. If that's something that would turn you on, I think you should come out to watch."

This was a plan Lily was happy to take part in. Your face was barely wet when you heard movement behind you. You glanced back to see Isabella trying to be invisible as she sat on a patio chair with a clear view of the two of you.

By the time you were done with Lily, you looked back to see Isabella breathing deeply, trying to hide the way she felt seeing Lily get off.

You headed into the house to find something to wipe Lily's wetness off your face. As you walked by Isabella, you whispered, "I think you remember that you're not allowed to get off without permission, don't you?"

She growled as you walked away.

As the day ended, you snuggled in happily with Lily and Emma. You heard Madison from the next room, "ew, not here."

A few seconds later, you saw Isabella at your bedroom door. You answered the question before it was asked, "find somewhere else, Isabella."

She wandered off to find another bedroom. Or not. Whatever.
