I’m really hoping that the guy who’s fucking her in the first page is Alex. I don’t want her to become a slut for whatever farmhand is available.

Bill

It would suck if she became a slut tbh, I love her and Alex and a cow dna shouldn’t change that especially because cows mate for life.

I was thinking the same things as OP, seems like it turns out well(Perspective) for her and her boyfriend gets the short end of it. Doesn’t seem like Mum’s track record but anything is possible when transformations is involved.

Aust

i’d be nice if the boyfriend does something to himself so he can constantly be with her and screw her. If he can make her a cow he can make himself a stud (literally or figuratively). What do you mean by Mum’s track record? Is she known to do stuff like breaking up loving couples? I’m not familiar with any comics besides the ones posted here.

Having the girl taken away from the love interest doesn’t fall TOO in line with other comics here on the site so it doesn’t fall with Mum’s track record of being for the love but you never really know.

I hope it is Not Alex. Rough strong guys get hot girls. Shy and nice guys get no girls. I hope it is Brad.

Guest

There’s nothing to say Alex couldn’t get strong. Brad is a horrible person and treated her horribly when she wasn’t hot. If anything Brad should be turned into a cow too.

Alice

well to be honest, he looks ALOT bigger than Alex, like both taller and wider, so probably not. Unless it randomly shows them older in age later in the comic. Also in page 34 he looks like he reacts to her transformation badly, so rather sure this isnt going in Alex’s favor, he seems like a cuck anyway tbh.

It’s sad how this started really well but the author tried too many things at once and made it into a big mess. The people who liked the characters got it ruined because this is going more and more on the way to becoming a depressing NTR thing just for the shock value. The people who came for the fetish stuff got it ruined because every time it looks like something is going to happen there are 10 pages of flashbacks. The people who liked the plot got it ruined because as soon as the fetish stuff begins all character… Read more »

Alice
Guest

yup, she realized he needed the cuck treatment, finally realized he was one. plus thats a tactic most women use to see if their guy will give up easily, which he failed by just walking out, especially after she was showing to be very scared and in such a traumatic situation to just leave like that is a cuck move so she made the right call honestly.

Looks like this is starting to derail from the kinda sweet route it started with. Cool for people who are into that I guess but there’s so much of that around I was kind of hoping it would stay the course.

Artimus

I’m honestly confused by now. For the first 20-ish pages, I thought the point of the comic, story-wise, was to make people root for the couple to say together despite all the shitstorm (weird plotholes aside). Now, 40 pages in, they’re trying very hard to make us dislike Cassie too? Like… what’s the point of this story, just making everyone equally depressed? I’m not sure if even that is working because if you throw so much stuff at people they’ll just stop taking the plot seriously, eventually.

I really hope that Brad fag will end up becoming a cow too. He deserves it.

James

No. Brad doesn’t even deserve the privilege of becoming a cow with a huge cock. No he deserve to turn into a shrew (they have the smallest penis in the animal kingdom excluding bugs).

Bubbles
Guest
Bubbles

You know, i didn’t mean him becoming a cow and still having a cock. I was hoping he will become the same kind of cow Cassie is: with a nice cow pussy and big udder. It would suit him, don’t you think?

James
Guest
James

Yup, but he gets Tiny tits.

Bubbles
Guest

It would leave him too much time for himself. Bigger tits = more milk = longer milking. Cassie has some time for herself, Brenda shouldn’t. I’d keep her constantly milked and bred.

Never saw a comic trying to destroy itself so hard, it’s incredible. First she’s in love with him, then she want to stay cow getting mad that she wan’t to deal it by her own (because of course why not, you’re clearly the genius here), reject him, and then POUF p.38 they talk to each other again but “anyway i’ve got to go instead of talking with you even if i asked you if you want to dance with me” that makes no sense …

The reason that’s happening is because of the flashbacks, but that makes it even worse to be honest since all this time jumping around in just a few pages makes it so hard to follow anything, I’m not much into the cuck fetish but I don’t mind it, yet still I’m struggling to carry on reading this due to how hard it is just to follow the plot above anything else. I’ll get marmalade mum’s patreon once they’ve finished up this series because they’ve completely lost my trust with both this comic’s own story telling and mum’s lack of wanting… Read more »

Ahh nuts, I was hoping for a sequence of Cassie’s initial growth transformation, instead of just jumping to the results. Still loving it though!

Mum still has the option to have Frame 1 as a “midway” sequence. There is no reason why the changes could not continue, amplify, go full Kurabayashi Chris, etc. Also, there is already an aspect of the mental/thought progression present in other Mum sequences, such as Jordan. I see limitless potential for this artist.

I just hope Alex actually gains something or has any meaningful development by the end of this. It will be really sad, both emotionally and for the wasted storytelling, if the only purpose of the character is being a scapegoat for all the bad shit that happens for the entire story.

Spindler

Oof, this is only getting more confusing with each page. And not only the plot, but what the story even is. With this many flashbacks, weird retcons, and charactets completely changing their behavior every other page, it’s starting to look like this is being written by two people with different, almost opposing views on what the comic should be, and they are constantly fighting to take over. The premise was super cool, and I don’t personally mind the cheating stuff if it makes the story interesting, but if the writing’s gonna be like that, I’d rather have two separate comics.

Ahhh so she was a cowslut before the serum… I honestly think if we saw these scenes in order the story wouldve worked a lot better. Cause then her transformation would be a lot more satisfying (and be more streamlined) the audience could feel bad for Alex without feeling like Cassie is literally insane but clearly she was using him from the beginning. Hopefully after this flashback the story can continue without pause. Im still rooting for some dude to get a horse serum, if its Alex better, but if not well itd still be a nice addition. Glad to… Read more »

why does this comic wastes so much time with pointless drama? the whole point is simple porn, there are 45 pages in total and only like 15 of them is actual TF porn, everything else is unnecessary exposition no one really cares about, what is worse is that when the comic actually gets into the TF parts the artist suddenly switches to a flashback for no reason, just who the fuck can stay engaged on patreon for this stuff?

Wrectify

In all honesty, from what we’ve already witnessed, I don’t think MM wants to tell another hentai story, where the majority of pages are porn related. I’m guessing Mum is trying to expand their skills whilst giving us more than what we are used to. If you think about it, it’s quite admirable and on the same level of awesome as Melkor Mancin and all the big ones.

Spidery7
Guest
Spidery7

I like your optimism, but in reality I think the comic was just a bait and switch. The guy in the first picture was intentionally left without any defining features so that we’re left to assume it’ll be Alex. The comic was drawn out to siphon as much Patreon buxx as possible, and now that MM is satisfied with her catch, she’s being extremely cheeky in the comments. I think that the only thing saving this comic would be just getting to the porn. There’s hardly anything MM can salvage story-wise (besides Alex+Cassie’s romance), and if MM were to stick… Read more »

How clever, the antagonist of the story is the rational, shy and empathetic introvert, who gets cucked right after his bipolar girlfriend abuses him to solve her low self-esteem and with a newfound pair of titties and a bunch of confidence gained via manipulating him, she goes back to her ex-boyfriend, whose paper-thin personality describes him as “like soo hot and super forgiving”. I can’t get over how clever this is, well done MM

Well then WHERE’S THE FETISH?! The comic hasn’t actually gone anywhere, because MM, instead of just getting to the transformation, tries to convince her audience with a metric fuck-ton of flashbacks that Alex is worse than Hitler because he’s CONCERNED for Cassie’s sudden cow-ification!

And as for all the drama in the comments, while there is validity in taking criticism and its good for an artist to take in the comments and what fans want; its also important to realise that this is the artists vision and as MM said themself, the story is pretty much already decided.

The western porn comic industry did not exist before Patreon, and it could not exist without it. What, do you just expect an artist to work for 6 months completing a comic without getting paid that whole time, just to release it for 20 bucks where maybe a dozen people buy it before it gets dumped on some porn comic site? At the end of the day, you’re getting the comic for free while Patrons foot the bill. The end of Patreon would mean the end of the high quality western porn industry.

I love this story so much! I can’t wait to see what you have in store for her! She is a victim, and the story has such a bitter sweet tone. Whether she is taken advantage of by terry, or voluntarily seeks a new life as a cow girl. Alex may not be able to handle her new persona, and desires. Possibly rejecting Cassie at some point? The mantra, “Nice guys don’t get laid” (regardless if its true or not) is heart breaking but gives the story such depth, and feeling. Though I may be the only one who feels… Read more »
