Clean-up and questions

Feeling completely spent, you pulled out of Rosa and fell beside her on the bed. She stayed as she was, face on the pillow and ass in the air, panting heavily as cum started to drip out of her pussy.

"Lucia, why don't you be a good host and clean up your sister?" You said, pointing to the white goo.

"Of course, love!" She said before quickly repositioning herself and diving into her sister's muff. Rosa moaned in response to the stimulation, still sensitive from her orgasm.

Turning on your side to face Rosa, you gently pulled now messy her hair back from her face and asked "did you mean what you said about joining us permanently?"

"I mean, it was kind of a heat of the moment thing," she said, pausing to think about it, "but I'm not opposed to it. What would that entail?"

"Well, I guess it would mean that you follow the same rules as Lucia about following my commands, not wearing clothes in the house, no limits and all that."

"Mmm..Well I'm not sure I could commit to forever like she has but I'm, ah!, open to committing for a year or two and re-evaluate after that. But only, ahhh, if Luce is okay with it, too!"

You were impressed how thoughtful she was able to be with her own sister eating her out. "What do you say, babe? Want to make it a trio?"

Lucia finished cleaning her sister's pussy and responded "If it will make you happy, then I'm completely okay with it!"

"I guess that settles it then! For at least the next few years, you'll have both a slut and a whore at your service!" Rosa said giving Lucia a wink.
