Two things are missing

It took a few days for you to fully recover from the girls' generous reward. A few evenings later, Lily had followed Madison to her room. Happy wet sounds were making their way out of the bedroom. Emma curled up beside you on the couch.

"I miss you Emma."

She looked at you confused, "what do you mean?"

"I'm glad you're having fun with Madison, but I miss falling asleep with you and Lily. It's always the best part of my day."

She thought a moment and responded, "wait, let me get this straight, do you remember..."

Shit. You knew where this was going. The conversation was suddenly out of your control.

Emma continued with a gleam in her eye, "...that first time I licked your cum out of Lily's pussy?"

"Yes," you said, defeated.

"The best part of your day was bedtime?"

"Kind of, yeah."

"And when I deepthroated you until you came down my throat and we all made you cum until you were delirious? Your favorite part was sleepy time?"

"Ah, no," you were back in control. You said smugly, "you slept with Madison that night."

Emma looked at you like you had some kind of brain injury. Then smiled. Then wrapped her arms around you, "I love you."

"I love you too." You held her for a while, and considered how great your life was.

But that wasn't where you were taking the conversation, "it would be rude to leave Madison alone, but I wish I could have the both of you with me."

She looked at you, thinking about the problem. You knew her well enough to know she saw the same solution as you. "So..." you prompted.

"So... we need another girl."

"We need another girl," you confirmed.

It wasn't long before Emma was sitting on your lap with her phone, scrolling through her socials, suggesting candidates. Emma was popular enough in this small town that she knew pretty much everybody. There were a lot of interesting options.

"Oh wait... oh... Abby?" She showed you a picture.

Abby was blond, a little softer than the three petite girls you had in the house so far. She was dressed fairly plainly in all of her pictures, but it was clear that she had something your house was missing: tits.

"I don't know though. She's pretty conservative. She probably wouldn't be into it."

You gave this some thought, and concluded: tits.

Lily had reappeared, wiping Madison's wetness from her face. Emma asked, "you know Abby, right? I don't think she'd be into... joining us, would she?"

She laughed, "no way. Her family goes to the same church as my parents. They're all... super into it. Her father probably welded a chastity belt on her."

Tits.

You convinced Lily to invite Abby over.

When she arrived, all of you had again found some clothes. Madison realized, "oh my god, you all had clothes on when I came too," and laughed at how far she had come.

When the doorbell rang, you greeted Abby, "hello Abby, I'm John. Welcome," you motioned for her to come in, "I think you should come in. I have heard a lot about you and I'm looking forward to getting to know you better," you lied. Tits.

After some introductions, you sat on the couch beside Abby, "I hope you understand that Lily, Madison, Emma, and I are all very... sexually open with each other. I think you will be able to accept that."

You had deliberately left Abby out of the list of sexually open people, but that suggestion still hurt. She had been repressed for long enough that accepting any kind of sexuality was not going to be easy for her. She was going to be a challenge, but on the other hand, tits.

You continued, "you're welcome to stay with us here as long as you want. While you're here with us, we'll do our best to make you comfortable, but if you see any of us doing anything together I think you should be comfortable with that."

Again the pain. It had been a while since you felt it: Emma and Lily were happy members of your household by now, and in retrospect Madison had been fairly easy to bring on board. Abby was going to take longer.

Getting her to move in probably wasn't going to happen right away. You settled for, "I think it would be nice if you can hang out with us for the evening." That was okay, at least.

After chatting some more, you decided it was time to get things moving. Also, it had been several hours since you had cum and you were now unaccustomed to that. You took Emma by the hand, led her to the bedroom, and left the door open.

"Don't be afraid to be a little loud," you whispered.

She laughed, "maybe you should have brought Madison."

You smirked at her, "oh yeah, okay. You go back. Send Madison in." She laughed again, and pulled you onto the bed.

Emma kept up her end of the bargain. There was no question that Abby knew what was going on.

You were laying with Emma catching your breath when Lily peeked her head into the room.

You quietly asked, "how is Abby doing?"

"I thought her head was going to explode," she chuckled, "she was all red and stared toward the bedroom the whole time."

You and Emma found your clothes and returned to the living room. Abby was looking at you and Emma wide-eyed.

"Abby, are you okay? I hope you didn't mind Emma and I... stepping out for a few minutes. I think it's important for us to make each other feel good."

"Yeah, it's okay. It definitely sounded like you both... felt... good."

"We did," you smiled.

You sat down beside Madison as the girls talked.

After a few minutes, you got bored with the conversation. You reached over and rested your hand on Madison's crotch, lightly caressing her. She opened her legs to give you easy access. You whispered in her ear, "shhh."

Abby hadn't noticed yet, but that was fine. There was actually something enticing about having clothes in the way for once. You felt the warmth of her pussy through her shorts, and enjoyed Madison trying to keep quiet while you played with her.

Abby glanced over when Madison quietly gasped. She looked down at your hand and stared for a moment while she processed what she was seeing, then averted her eyes.

You slid your hand inside Madison's shorts, finding her pussy wet from the attention. She involuntarily gasped again. Abby steadfastly looked anywhere else.

As Madison found it harder and harder to keep quiet, you caught Abby sneaking looks, confirming what was going on and trying to simultaneously look and not look.

When Madison was getting close, you whispered, "you have to be quiet." You brought her slowly over the edge and tried to not totally overwhelm her. She did her best, only breathing heavily and with a few quiet gasps.

As you slowed, you glanced at Abby. She had given up looking away, and was staring at your hand disappearing into Madison's shorts. You slid your hand out and leaned over to kiss Madison.

When you pulled away, you looked back to Abby, "oh sorry, did we interrupt?"

"No... no problem." Her eyes were still on Madison's crotch, "it's getting late. Maybe I should go."

"Okay. I'm glad you could come over, Abby. I think you should come back tomorrow. We can get to know each other more and I think you can learn more about how we make each other feel good."

"Yeah... okay," she said dreamily as she walked out. It was probably best that you send her home for a break.

You and Lily walked Abby to the door. By the time you turned around, Emma and Madison were already pulling each others' clothes off. You led Lily to the bedroom.

She knew Abby the best. You asked, "do you think Abby is going to work out here?"

"I don't know. Her whole life, she has been told everything fun is evil."

You looked at her, "so have you. You turned out okay."

She smiled back at you, "yeah, but I was never really into it. She is."

You wrapped your arms around her, "how about we find something you are into?"

You left Emma and Madison to their own activities, and led Lily to the bedroom.
