Skip ahead to picking up Erica

You dig your fingers into Erica's soft yielding ass, then push one hand up her back, pushing her torso down further even as you drive your cock up into her pussy. She moans with the fast pumps you give her, keeping your shaft almost fully seated, just banging away at her depths. It feels incredible, the sensation of her warm wet velvet walls, but in particular is feels great to fuck a pussy after hours of self-imposed 'celibacy' around Melanie.

You grab her well rounded hips as you slowly withdraw; thinking of teasing Erica you pull out completely. However, the strong throaty half-groan you get from her changes your mind and you follow up with a short pump of just the head and a couple inches. You pull back and fuck the entrance of her pussy repeatedly and Erica groans, “Oh! That's good. Yesssh...Uh..uh.” You feel a powerful sensation of masculinity at this indication of your apparent sexual prowess and you honestly can't wait to have your 'mother' in the same position, hopefully with Greg right there beside you.

Switching it up, instead of driving your hips forward, you grab her fleshy butt and pull her lower body back and forth upon your cock. You continue to fuck Erica doggy-style for another five minutes before you finally grunt out, “Uh! Oh god, I'm going to cum!”

Erica's reaction is instant, fucking her hip back against you as she calls out, “Do it, baby! Cum! Wherever-in-out-I don't care- Just do it!”

And you do it with your cock-head knocking at the entrance to her womb, you pulse out several long loads of hot cum as you groan, your face contorted in surely an absurd expression. You continue to blast out load after load into her completely uncaring as to the consequences, and it feels fucking amazing.

Ten minutes later, you are still lazing on her bed as Erica finishes putting on the outfit you picked out for her, consisting of a baseball cap, a tiny pair of jean shorts that barely cover her ass, and some stripper heels. She adjusts herself as she looks into her full-length mirror, not bothered at all about the prospect of being completely topless to go outside. One of her hands presses to her crotch as she smirks at you in the mirror, “Damn, I think I need a tampon! Your guys are still leaking out of me! Like, I can see your big nuts there, but this is ridiculous. Seriously, how can you have a hard-on just from looking at me after all that you let out?”

You shrug as you reach around the offending erection to feel at your sack, “These are bigger than normal?” And you can tell they are; apparently extra length and girth wasn't all the mysterious voice had done.

Erica made her voice jokingly disbelieving, “Oh like you don't know! Next you're gonna be like- Huh-what? I have big dick-what?” Her tone changed to admiring remembrance, “Seriously, fucking amazing feeling those low-hangers banging against my clit in that position!”

You get off the bed and put on your own clothes, suddenly anxious to get to your family with Erica. You've already taken care of the apartment issue with your landlord. After having her middle-aged pussy introduced to your apparently always ready cock, Ms. Thomas will be paying you the 1150 a month from now on. She's got Melanie's address and has even agreed to deliver the rent in cash in exchange for more deep-dickings. Thanks to you, she has the strong belief that after sex with you she won't be satisfied with anyone else and it is money well spent.

You don't really need the money, but you figure you can should add to the family income if you are going to be living there.

With a hand on Erica's lusciously big ass, you two exit the apartment and head to the car.

“So tell me again. Who is it we're going to live with and how is this working exactly? I'm kind of confused. Down for whatever of course, being your personal cum-slut and all- just I'd like to know what to expect?” she asked with honest curiosity.

You tell her not to worry about it for now, but that was a good question and one you hadn't quite decided on. Were you going to add Erica to the family? Or just present her as your little slut and go from there? That would certainly work but you were kind of hankering for some more weird taboo stuff. Adding her to the family as your sister would work. And you liked the idea of her teasing her 'daddy' Greg a whole lot while only you would get to actually fuck her. Another idea that you were really in to but were also not sure about was introducing Erica as Hannah. As their currently 6 month old daughter but somehow sent back in time. It was completely off the wall, especially the idea that you could actually make Melanie and Greg believe something so absurd. But given your power, certainly not out of the question. It just made everything even more taboo and exciting and you really wanted to do it.

But then there was what Erica should believe? Should she believe herself to be Hannah from the future as well? And would that destroy who she was as your cousin Erica?

Huh. It was something to think about. And think about it you did... as Erica gave you some truly precious road-head on the way over to the house.
