well the entire human gene pool is doomed

Oh man, you really captured the essence of Grunkle Stan there. And I'm hyped for next chapter too.

*massive spoilers for Chapter 3*

Poor Dipper. Anyone else would be pretty happy with being friends with benefits with Wendy Corduroy for two summers, but Dipper is not just hot for her, he is truly and well in love, and unfortunately, she is not, in any universe. I like how his memories of that reality really didn't help him realize that was the catch, mostly because alter-Dipper also didn't realize, and was willfully deceiving himself. The foreshadowing with the soda gesture was brilliant. I sort of intuited it might be heading that way when she didn't remember the detail that had so much significance to Dipper, although one could also interpret it as Dipper being in general more given to notice details than Wendy. Actually, I kinda expected a worse outcome. Something like Wendy being the type of girl to never call after they have done it and Dipper feeling used. Your version still paints Wendy a lot more sympathetically. At worst, she let Dipper deceive himself. At best, she honestly thought he knew what the deal was. Which makes sense, if she is roughly the same character as in cannon, modulo the werid world-wide fetish.

The sex scene was both pretty darn hot and super fun in how it plays around with the usual expectations. For example, Wendy being turned on by Dipper exaggerating his age... downwards, and this gem of a line: "Yes, baby, keep sucking, suck them for me, it feels so good..." Somehow Wendy sounds like a male pornstar there, and since it is Wendy Corduroy we are talking about, I am not 100% sure that's due to the shotaverse.

Also, remember how you always get your protagonists ridiculously in character even as you are making children cartoon characters star in a porno? Well...

> Jeez, he thought. I’m second guessing my second guessing. I’m third guessing myself.

That, right there, is Dipper in a nutshell! Kudos. And, of course, similarly:

> “State law says I have to give you thirty minutes,” the old man replied. “So I’ll give ya fifteen. I call that a reasonable compromise.”

Is the most Grunkle-stanish thing I can imagine.

By the way, I thought we both agreed Grunkle Stan's sex life in the shotaverse was something no one should have to think about. The idea of Stan getting it on with catheterized nonagenarians is definitely not a mental picture I needed. And I am already bracing myself for dreaded Chapter 4... "Oh boy" indeed. But if it is this early in the line-up, then it cannot be the fic's conclusion (my money is on Dipcifica only because you brought her up on Chapter 1, then again, I know that's what you want us to think... Mmmm... plots within plots).

Also, I kind of imagine your Aphrodite singing this when she answers the phone, but in a bored nasal tone: https://www.youtube.com/embed/XmdJcOI5YLQ?start=35&end=44

Hey, pretty cool chapter. Thanks for making a fanfic that includes Dipper (as we know him) with Wendy. Very in character everything (Dipper behavior, Wendy's, etc). Also, meanwhile tragic the ending for any fan of DipperxWendy, it is believable that even with that little change (girls liking younger boys) Wendy would reject Dipper. I mean, this is not because of age (three years is not that much of a difference nowadays).Wendy likes Dipper, but I think that unless some changes (for any author), it would be difficult to find a reason for her loving him like that..... 

I know that this is too much to ask, but could you make a long omake (I know they are short, but I am already asking, so why not asking for longer) of a threesome between Dipper with Tambry and Wendy..... XD

Very nice, what I wouldn't give for a world like that.

Gotta hand it to old Aphrodite, she doesn't do things halfway. Giving the girl you like the right fetish so that she will go out with you is one thing, but giving that same fetish to the entire universe? Whoa! (and yes, I know she is just sending him to a pre-existing reality where that is the case already, infinite chickens crossing infinite roads and all that, but she could still have sent Dipper to a closer reality. You know, one in which his sister is not also creeping on little kids... ).

Speaking of which, creeper Mabel is just perfect! She is in-character-modulo-universe, since canon Mabel is the queen of creepy crushes. Is just that it becomes so much more disturbing in the "Straight 'Shooting'" reality (loved the pun when she mentioned it, and did a double take when I saw the Chapter title the second time and now got the joke). And, since we are talking about people who are in character, this is the first line in the chapter that made me laugh aloud: "and Thompson was…still Thompson, apparently." Poor Thompson. Not only is he still single in this reality, but his social situation is likely particularly awkward since it means he mostly hangs around boys much younger than him and their dates, rather than with guys his own age. I also like that Dipper, despite his apparent good luck, is already suspicious of the Gravity Fall weirdness in question, even when it is benefiting him this time.

Third line that made me laugh aloud: "Spackler’s Underground Pest Poison: For Moles, Voles, or Whatever Lives in Holes.", specially when billed as gnome repellant. No big profound reason, it was just hilarious. The second line was Mabel's title drop, btw.

Regarding the, right now very incipient, smut, I like how Dipper is super nervous, and apparently was super nervous too in the past of this reality. I also enjoy how Wendy would be a pretty, well, gentlemanly?/romantic?/sweet?, in the more conventional case where the genders were reversed and the ages of both were bumped a bit higher, since she is taking care to make Dipper's first time special. In general, this chapter had me thinking about which social conventions would change and which would remain the same in a world were it was the norm for the girl to be the older one (ok, and fine, I am imaginning this stuff being more 15 to 17 than 12 to 15 because... eeh... despite the fact that I have both read and written worse :p). Does the change also make the girl the one who initiates/escalates by default? Does that make guys more wary about potentially pushy girls? (not just in the 'Mabel going after way-too-young kids' case, but also like, even Robbie and co. if their dates turn out to be less considerate than Wendy seems to be so far with Dipper...).

Also, Grunkle Stan's encounter with the Hand-Witch in this reality is something I am not sure if I am either curious about, or, more likely, really really don't want to know about ;)

Oh. My. God. If you write a Wendip story, I will praise you unto high heavens, man. 

I'm pretty sure you already have an inkling of where I hope this is going ...

Regardless of where it leads, I'm certain I'll enjoy it. Looking forward to what is to come!

Your fics are always so good, I can't wait for chapter 2! 

> “Aww, you’re scared. I’m not gonna hurt you, hon.” The voice grew nearer to Dipper. A feminine form appeared in faint silhouette. “I’m here to teach you about girls.”

"Ooooh my..." - George Takei

The concept for this fic sounds really intriguing, and I love the rendition of Aphrodite as this sort of cougar / madame person. Even though no much happens on the first chapter, it sets up the series quite excellently. I already know this is going to be one of those works of yours that I look forward to, installment after installment. I only wonder how long it can truly be, is that one reality per girl and one chapter per reality? Or multiple ways it can go each? I can think of three girls it would make sense to pair Dipper with, maybe four... unless... oh no.

There is a pincest option, isn't there...? The worst thing is, if is you writing it, I would probably read it >.>

hope it's Pacifica he choose in the end

already off to a good start, i hope theres pinecest!
