Yes, she finally can

You woke up with a much better plan. After some breakfast, and a 69 with Madison, you took Abby into her bedroom so you could talk in private.

"Abby, I think you are starting to understand how important it is for us all to give each other pleasure."

"Yes, I have learned a lot from you, thank you."

"I'm glad, but I hope you and I can do more with each other."

"I'm sorry, but I can't. I know I shouldn't do the things the other girls do with you."

You sighed involuntarily. "I think it would be important for your... personal growth to be more a part of the house."

"What do you mean? I can't..."

You cut her off, "I know you don't want to have sex, and I respect that," you lied, "maybe we can find something that isn't sex that you and I could do."

She looked confused, "like what?"

"You have been watching us all play, and I think you're comfortable seeing us cum together," no pain, she was okay so far. "There's something you do for me that the other girls can't. I would really love it if you could."

"What do you mean? The others do so much with you."

You looked down from her eyes, "your tits are so beautiful Abby. I think it would be unbelievable if you'd let me feel them. It would be amazing to feel my cock between them. I think that's not sex so you wouldn't be doing anything wrong." That was a bit of a stretch for Abby to believe, but the "not sex" angle seemed to have landed.

She looked down at her chest, "you'd like that? Even though you could do... other things with the other girls?"

Finally, a small crack in her defences? You decided praise was the way to go. "Yes Abby. I think it would be so wonderful for you to use the unique gift you have been given."

The was still looking down at her tits, seeing them in a completely new way. She looked up at you, "that's not sex, right?"

"Of course not. You have been using your fingers to get the girls off, and I think this isn't as big a deal because you're not even using your hands." You didn't believe it yourself, but Abby seemed to.

"I guess you're right. Okay."

Your cock was rock hard at the thought of finally feeling those tits. You stepped forward and cupped them, feeling their softness and weight in your hands, "my god, these are amazing Abby."

She was watching you massage her tits, "thank you John. You like feeling them like that?"

"Of course, they're so nice," after a few more appreciative moments, you suggested, "lay down on the bed." You climbed above her and reached down to feel her glorious breasts again.

"They feel so great. I'm so happy you're letting me do this. I think it's very special that you're able to do this for me. Can I feel them around my cock?"

"O...okay."

You moved your cock between her tits and cupped them, wrapping them around your shaft. You involuntarily sighed in appreciation. "Holy shit Abby, this feels amazing. I think you have been given such a special gift," you enthused. Maybe you were over-acting but you wanted to encourage her as much as possible.

"It looks so... indecent," she said with a mix of amazement and worry.

Your dick had been stimulated in many ways over the last few weeks, but this was a new sensation. The feeling of Abby's tits wrapped around your cock, while knowing how far you had to push to get her here, was amazing.

Abby was breathing heavily, obviously turned on my what she was doing. "If you want to play with your pussy, I think it would be so hot."

"I shouldn't... with you."

"You do it when you're playing with the girls. I think it's no different if you do it now. We're not having sex, after all."

You felt her arm reach around you. You glanced back to see her slide a hand into her panties. You felt her twitch below you when she made contact with her clit.

"You're making both of us feel good now Abby. You are so good at this."

Abby was watching your cock thrust between her tits. You could feel her arm racing behind you as it worked her clit. She was panting in excitement at everything she was experiencing.

So were you. You were holding Abby's tits against your cock, feeling them grip your shaft. You had worked so hard to get to this point, you were almost lightheaded at finally being here.

Abby was also amazed by the experience. She came quickly from the mental overload.

As her orgasm finished, you weren't going to last much longer. "this feels so good, Abby. Your tits are going to make me cum."

Her eyes widened looking at your cock pointing up at her. She looked up at you with sudden concern, "where will you...?"

"Can I cum on your tits? I think it would be so generous if you let me see my cum on them."

"Okay."

You let her sit up, "hold your tits up and give me a nice target."

She sat up and wrapped and arm under her tits, presenting them like a gift. "Like this?"

"Holy fuck, yes."

She squealed when she felt cum for the first time, but her attention darted between the cock that was covering her with cum and her tits that were being covered. She looked amazed that she had caused all of this.

God, her tits looked awesome covered in cum. When the eruption finally stopped, she looked down at her tits for a moment and said "it's so much! And it's so warm!"

You couldn't resist leaning down a little and wiping the last drop of cum from your cock onto a bare spot on her right breast.

"That felt so good Abby. I think you should be proud of how much pleasure you gave me."

"Really? You're proud of me?"

"Yes, of course. I think you should be thankful for the gift you have been given, and how well you have been able to use it."

She beamed.
