Time for a new addition

Emma was sitting on your lap, and you were idly stroking her pussy while she browsed her social media for others you might want to join your harem. She scrolled a little too quickly past a stunning brunette.

"Oh hey, who's that?"

"That's Isabella, but no. Lily wouldn't want her here."

"Huh? What do you mean?"

"All through high school, she was... really mean to Lily. She bullied her, I guess."

Lily had heard her name and wandered over, "her!? No fuck her, if she steps in this house I'm leaving!"

You tried to calm the situation, "it's okay Lily, I wouldn't invite anybody here if you didn't want her. You're as much a part of this house as me. You too, Emma." The girls smiled.

Wanting to get to the bottom of this, you asked Lily for more details about Isabella.

"Every time I turned around it was something else. I don't know why me, but she just wouldn't leave me alone. Like, every time she passed me in the hall for years, she pulled her eyes back like this." Lily put a finger on either temple and pulled back. It didn't actually make her beautiful almond eyes look much different, which was adorable, but this wasn't the time to find her adorable.

All you could add was, "wow."

Emma agreed, "it was pretty bad. Even her friends thought she want too far. I guess I was kind of her friend... not really, but it was better to be on her good side, you know?" she said apologetically to Lily.

"Yeah, I know. Oh, and last year, I was talking to a boy I liked at school. She stood beside me and shouted 'Okay everybody, we're going to have a smallest tits contest, oh never mind, Lily wins'."

"Wow," you added again. You made up your mind, "Lily, can you trust me? I want to invite Isabella over."

"No, please no!"

You continued, "but what I'd like to do is...".

Emma and Lily listened to your plan. Emma was enthusiastic, but Lily wasn't convinced.

"How about this? You can kick her out any time you want. No questions asked. You're in control."

She agreed angrily, "fine." Emma messaged Isabella and asked her to come by in the morning, with the promise of some gossip that had to be told in person.

When Isabella arrived, Lily refused to be seen, which was for the best. When you answered the door, again wearing clothes for an introduction. She greeted you, "who the fuck are you?"

You decided not to take the bait, "I'm John, welcome to my home. I think you should come in."

"Whatever."

You sighed, "I think you understand that we're very open with each other in this house, and all have sex with each other freely."

She somehow managed to convey impatience with a simple, "yeah."

You took a slow, deep breath. "I think you will be fine watching all of us do whatever as long as you're in this house, right?"

"Yeah, I guess," with an eye roll.

You had known this girl for 15 seconds and she was already getting under your skin. You said firmly, "okay then, I think you should sit your ass down on that couch and shut the hell up."

She huffed over to the couch and sat down with her arms crossed. Only once she had finished her performative irritation did she notice the TV. It was currently displaying, in full HD, a woman on all fours getting railed by a monstrous cock. She was grunting in some poorly-acted combination of ecstasy and pain. Isabella's eyes widened.

It took her another second to notice Emma and Madison naked on the other couch, rubbing each other's pussies while they watched. Abby was sitting nearby, playing with herself watching both the screen and the other girls. Isabella stared at their show. She obviously wanted to ask Emma what was happening, been told to shut up quite forcefully.

"I think all of this is probably a bit of a shock but," you added firmly, "I think watching other people have sex turns you on, right?"

"Uh..." it took her a moment to regain her tone and say condescendingly, "of course." She hadn't stopped staring at the girls across from her rubbing each other.

You went to the master bedroom to find Lily looking anxious. You kissed the top of her head as you sat beside her, "so far, so good. Are you sure you want to do this?"

"I can kick that bitch out any time, right?"

"Yes... and you're right, what a bitch."

You led Lily out to the living room, both completely naked. You looked first at Emma and Madison. They were clearly enjoying their role in all this. Madison had moved to the floor and had her face buried in Emma's pussy. Abby had taken Madison's place, and was playing with Emma's tits.

Isabella was staring wide-eyed at her friend receiving this treatment.

You got her attention, "Isabella, you know Lily, right?"

The girls glared at each other. Isabella clearly had something to say, but was still shutting up, as commanded.

You sat next to Isabella, and Lily sat on the other side of you.

Ignoring Isabella, you started to kiss Lily, reaching out to feel her body. Lily slowly relaxed, also started to ignore Isabella, and was enjoying the moment.

But that wasn't the plan. You caught Lily's eye and looked at her questioningly. She nodded.

"Isabella, I think you should stay right where you are. You can watch, but nothing else. I think you're going to be very jealous of Lily."

Lily knelt on the couch beside Isabella and leaned forward, leaving her on all fours across Isabella's lap. Isabella stared wide-eyed.

Lily moaned as you slid your cock into her. Her panting and moaning as you fucked her was perhaps overly theatrical, but you weren't complaining.

You chanced a glance at Isabella. "Stacked" was the word that came to mind, and her tits were jiggling in-time with your thrusts into Lily. She was staring at your cock as it slid in and out of her.

You leaned forward, loudly whispering to Lily, "your pussy is so good, Lily. Does this feel good?"

Again, with a little more enthusiasm than was necessary, "oh, fuck yes! It's so good!"

"But Isabella won't get to feel anything like it, will she?"

"No, she fucking won't!"

The plan had been for you to cum inside Lily, but having had the shortest introduction to Isabella, you decided she deserved more. Just as you were about to cum, you pulled out of Lily's wonderful pussy, and covered her back and ass with your load.

Isabella stared down at Lily's cum-covered body. Lily subtly wiggled her bum back and forth, making sure Isabella's attention didn't wander.

You looked at the mess you made on Lily's back, and back to Isabella. You muttered to yourself "smallest tits contest" and made another decision. You said as firmly as you could, "Isabella, I think you should take off your shirt and give it to me. Now!" The shooting pain in your head was overshadowed by the thought of anyone being cruel to your sweet Lily.

Isabella was obviously still unsure, but obediently removed her top, leaving her beautiful round breasts on display in a lacy bra. You used her probably-very-expensive shirt to delicately wipe your jizz off Lily's back.

Lily realized what you were doing and made a noise that made you think she might cum just from the feeling of a shirt on her body.

Your cock was still wet from Lily's pussy and your cum. You pointed it at Isabella's mouth, "want to lick it clean?" She looked at you with horror.

You concluded, "no? Okay then", and casually wiped yourself off with her shirt, "I think you should wait for us here, and don't talk. It's better when you don't talk." You threw the shirt on Isabella's lap, and took Lily to the bedroom.
