No, she can do it herself

You thought a little about how to get Abby more into you, or the girls, or whatever, but were quickly distracted by Emma and Lily. You sat beside Emma, pulled her onto your lap, and took over from Lily rubbing her clit. Lily found a nearby vibrator and brought it to her own pussy, buzzing away as she watched you play with Emma.

As you joined the girls, you noticed Abby slowly stop what she was doing. She was intently watching you play with Emma's pussy.

You lost yourself playing with the girls for a few minutes. When you looked back at Abby, she was still standing in the same place, holding the same plate, still staring at you. The only difference you could see was that she was breathing a lot deeper than before.

Maybe it wouldn't hurt to ask, "Abby, would you like to join us?"

She continued to stare at your hands playing with Emma. "I can't."

Okay, new strategy. "No, not like that. I think you would feel better if you played with yourself. I think giving yourself pleasure would be a... virtuous thing to do."

"You mean... here? You'd be able to see."

You considered pointing out that you literally had a finger inside Emma as you were talking, but decided on, "you have been watching us have fun for the last two days. I think it's reasonable for you do to the same."

"I guess you're right." Your head throbbed, but it was progress.

She walked out of the kitchen and slowly and nervously sat across from you. She undid her pants and slid a hand inside. She apparently had no intention of taking her pants off, and you had pushed her far enough that you would rather get back to Lily and Emma.

You resumed rubbing Emma while Abby watched. You made sure Emma's legs were spread wide in Abby's direction so she could see exactly what you were doing.

Abby was definitely enjoying herself. Her hand was making slow, deliberate circles inside her pants, and her chest was heaving.

You reached for Emma's breast. She moaned in appreciation. You hoped Abby would take the hint. She did. Her free hand found its way to her breast, squeezing it firmly.

You were hitting Emma's buttons, "holy fuck don't stop," and then, "fuck yes! Fuck!"

Once Emma's breathing slowed, she slid off your lap. She decided you were being ignored, and dropped to the floor in front of you. She wrapped her hand around your shaft and guided it into her mouth.

You reached over and took the vibrator from Lily, holding it against her clit. You lost track of Abby again as you concentrated on Emma and Lily.

When you looked back to Abby when you heard a quiet gasp from her direction. Her eyes were darting back and forth between Lily's pussy and Emma's head bobbing up and down on your cock. The hand on her breast was gripping it tightly and she was obviously very close.

The sight was too much for you, and you started to cum in Emma's mouth. "Oh my god Emma, you're so good... holy shit...".

This was apparently the last inspiration that Abby needed. She gasped and said as quietly as she could, "oh yes... yes... yes... yes!"

As her breathing slowly came back to normal, she remembered there were other people in the room. All of you were watching her, and she seemed suddenly embarrassed.

You intervened, "Abby, I think you should know how hot that was. We're all very happy you're feeling more comfortable with us," you looked at the others, "aren't we?"

There was a chorus of agreement from the room. "I think you should feel comfortable doing that whenever you want around here. We all love seeing you satisfied."

"During the day," Madison muttered.

For the rest of the day, you let Abby be. She seemed happy to be watching all of you, and lost her shyness playing with her pussy around you.

Also, she had apparently decided that taking care of chores was something that made all of you happy, and the house had never been cleaner.

Later in the evening, you were all experimenting with your toy box. You and Lily were using the ramp/wedge, no longer questioning Madison's purchase.

Emma was getting more comfortable with the strapon, and Madison was happily on the receiving end of her practice.

Everybody was having fun, even Abby who had her hand in her shorts, watching everybody play around her. You looked up from Lily, and couldn't take it anymore.

"Abby, isn't that uncomfortable? You know you can take the rest of your clothes off with us."

"Yes, but I don't think that's something that would be right for me to do."

Sigh. "Okay... but you go to the beach, right? You could just leave on your panties. I think that would basically be the same as a bikini bottom."

"Oh... I guess, yeah."

She stood up and pulled down her shorts. You finally got just a little better look at her body.

You decided to call it good enough for the day, and focused your attention back on Lily, with the occasional look at Emma fucking Madison, and Abby much more easily getting herself off.
