Keep it simple. No need to add more emotional bonds.

You decide it's not necessary for your new parents to believe these two lovely girls are their real daughters, they only need to be willing to accept them as family basically. Not only that, it would save trouble if they wanted to leave. As for yourself, you still aren't sure what the impacts are if you decide to leave. For now, you have no plans but you hoped it would be as easy as telling them to forget everything and focus on raising Hannah.

As such, you decide to speak for Erica and Gemma as you reintroduce them. You already have a story to go along with each of them to ease them into the family.

"So as you already know, this is Erica, who I refer to as cousin sometimes, but she's probably more like a big sister to me. She was the one who basically helped support me along with her mother while I was searching for you and dad," you explain, feeling a little guilty to be expanding the big lie you injected into Melanie and Greg's mind, but right now, you wanted this family to grow bigger the easiest way.

You pause, letting Melanie process the information. She nods graciously at Erica with misty eyes, but she forbid herself from spilling more tears. With a sniffle, she smiles warmly.

"I...can't thank you enough. You've allowed us to see our baby boy again. Thank you!"

"Uh..." Erica feels rightly uncomfortable and looks to you confused, but with your nod and reassuring smile, she smiles back at Melanie, training her mind to act accordingly. "It's...no problem. I'm here to please my little bro, after all."

You clear your throat, continuing on. "...I would like her to live with us and I hope you can consider her like a real daughter as she is like a real sister to me."

Melanie looks incredibly at ease as if your request is the easiest possible accommodation ever. "Of course! How could I ever say no to my own son's benefactor! You must invite your mother over, Erica. I have to give her my thanks as well!"

Erica smiles more naturally, easing herself into the warm welcome of her new foster mother. "Of course. She's little ways, but I'll be sure to invite her sometime soon, mom."

"Oh dear, that sounds so nice! Greg will be delighted to find that he has a new daughter," Melanie squeals a little, hearing Erica call her mom, "...of course, John calls me mommy, so you're free to call me that as well."

Erica stares at you, letting you decide, but if you truly wanted Erica to refer to your "mother" with such a sweet term, you would have suggested it. Instead, you shrug because honestly, it sounded better hearing her call Melanie "mom".

"That's fine, I'll stick with mom," Erica finally answered with a smile.

Speaking of mother, you hadn't given thought about Erica's mother, or more appropriately, Aunt Vivian. Perhaps it's because you haven't seen her recently in person, although you do talk to her on occasion. She's a nice woman in her late thirties with a well-maintained body, and an extremely cheerful personality, but you can start to remember why you don't talk to her that much even though you get along with Erica. She's kind of annoying. If there's one thing to say about her, it's that it feels like she laughs at everything.

Putting her to the side, you aren't sure if you'd let Erica invite her mother over or not. For now, the family is already big with two new daughters. It may not be good if it got any bigger.

Now with Erica formally in the family, it's time for Melanie to learn more about Gemma. The short police girl beside you was fidgeting, still a little nervous about the whole ordeal, yet she tries to remain composed.

Melanie furrows her eyebrows, "Actually, didn't we meet before? My son said you would be living with us from now on. Would you like to be a third daughter?"

Melanie appears to pick up quick. It may be that you would not have to do anything.

"Um...yes, I..uh..."

It seems she was having trouble expressing herself and it was very cute to see her fumble. Even Melanie couldn't help grow a little warmed by the short girl. You decide that you'll have to help her find the right words.

"Actually, I've helped her out with some issues and we decided to go out together. This may be a little strange, but I also would like her to be a little sister of sorts in the house and hope you can take her in as your daughter," you explain, continuing to be more open about the whole relationship. The fact that you and she would be dating and that you were asking Melanie to accept her as her daughter would raise some strange flags, but Melanie had fully grown accustomed to your word and accepted it naturally, just like with Erica. There doesn't appear to be any more reason to ease yourself in.

"Oh, of course! Sweetie, don't be so nervous okay? As your mother, you can be more relaxed around me, okay?" Melanie consoles, her eyes softening. It may have been your imagination, but you are almost certain that she has already gotten her maternal strings strung by the small girl in front of her.

Gemma forces herself to smile and grew a little red. "Thank you...mommy"

Hurgh!

You feel your chest tighten, the sweet sounds affecting you far more than it should have. You knew you made the right decision in supporting her role as the little sister. Actually, no...even if she became the eldest sister, the way she's expressing herself would always scream little sister!

Melanie appears to be quite shaken by Gemma as well, her eyes widen and her lips unable to help but slowly curl up. "Oh sweetie, you are too cute! My son is truly lucky to have found you. By the way, I hope you can forgive my son for that parking violation."

Gemma smiles more easily, just as Erica as she hears Melanie's compliments. To the parking violation, she shakes her head. "It's alright. Him helping me out is worth far more than any violation I've given out."

You are warmed to hear that from your girlfriend and now your little sister within the house. With that out of the way, your mind drifts off as Erica, Melanie, and Gemma are speaking out more comfortably about themselves. Yet, you are thinking about your many choices you had.

There's your thirst for Melanie and her delicious milk, Erica's thirst for your cock and you are certain about that since you see her glance at you with a twinkle in her eyes, and...Gemma, someone you wanted to gently ravish.
