This upcoming fanart was suggested by Lesbian Supremacist, one of the patrons. It's basically Luna with her hand tied in Nightmare Moon's neck while being stuck between her big breasts.
Last time I've drawn Nightmare Moon the final result wasn't perfect, but I'm gonna change a little bit the methodology for her based on the color scheme I used for rule 63 Sombra: A layer of grey, typical occlusion, but with a blue tone instead of red. Hopefully the final result will be much more appealing.
By the way, new sketches.

Here is Posey Shy working at Pinkie's with her apron, but she falls down and, without knowing, she does the Jack-O pose and she shows all her private places to Rainbow Dash and Sunset Shimmer. Drawing her with her glasses on is usually difficult, so, so make her trip even more sense, I've drawn her glasses on the floor.
Another one:

This is Pinkie Pie telling Mrs. Shy how to use the breast pump, but she doesn't know what a milf is. This is gonna be a 3-panels fanart, but the third panel is empty because I'll copy the second panel and change Posey's expression just to gain time.
I've written some ideas for this follow up. Here are some of them:
-Pinkie Pie admiring Posey Shy’s breasts in the back room, kissing them and kissing her nipples while her milk is leaking.
-Pinkie Pie milking Mrs. Shy’s tits from behind to get more milk.
-While Posey Shy is milking her tits, Pinkie Pie starts to eat all her private parts.
-Celestia and Mrs. Shy are working together, making more milk in many glass jars. Celestia seduces her and proceeds to kiss her, to milk Mrs. Shy’s tits (and express more milk) and to suck her nipples.
I have more, but these ideas are focused on Posey Shy working at Pinkie's.
I also have made another one:

One of the comments I've read about one of the last Posey Shy fanarts was that Celestia should help her. So I did, although it wasn't the first time I've drawn it. The first time had a different camera angle, right in front of Mrs. Shy. The problem was that, while the poses are fine, I thought Celestia's hands and Posey's breasts were a little weird. I'll show you the previous sketch later.
I also made a sketch of Sunset Shimmer with her casual clothes. I haven't scanned it yet, but I'll scan it and work on it later. It's pretty much like the last time I've drawn her a couple of days ago. She wears a jacket, a tank top with no shoulders, short shorts and some sandals. I'll also add the wedding ring to indicate she's married but I'm not gonna mention in DeviantArt she's married with Celestia despite dating Pinkie (funny story, one of my commission clients actually followed the whole story in my Newgrounds gallery and he told me about it a couple of days ago).
I'll start working on the Nightmare Moon fanart now. I don't think it will be finished for tomorrow, but I'll show you some WIP images.
I hope you like the sketches and thank you very much for your support!
Love,
