This is the new cover art for Pregnant Party Pony Present Predicament by Kassaz, based on an early scene:

She should probably stand up again, but this was easier to think than say, and easier to say than do. She tried leaning forwards, but crushing her midsection was uncomfortable, for both ponies involved, and the little let the larger know it, so she put a hoof to her chin while she thought about how to valiantly rise above her present predicament, her current crisis, the crisis of a pink, pregnant pony baking cupcakes who was having issues standing up, on Hearth’s Warming Day. She could call for help, and it would be fine if Mrs. Cake came, but if it were Mr. Cake or her hubby, they may later joke at her expense and, while it would probably be funny, she’d been so good about making most of the jokes about her pregnancy herself, and didn’t want to allow them an easy victory.

Her eyes lit up when she found her solution. Curling her body up just a little, as she had done before, she lay flat on her back. She could see just the tips of her hindhooves over the pink mound jutting out of her. Then, no differently than if she needed to sweep the kitchen and couldn’t find a broom, she wiggled her body back and forth across the floor, but this time her goal was moving the more modest distance towards the island counter nearby. Her center of balance had shifted a few hoofs up and out from beforehoof, back when her barrel was flat, but she’d had plenty of practice by this late stage.

Her hips and shoulders twisted, and she giggled yet more in watching her belly sway back and forth, being careful to avoid falling over. Once she’d made herself perpendicular with the counter, she managed to gyrate her hindquarters upwards with it. In less than a minute, her body was upside-down and vertical, with her forelegs curled up with her head, and her large, pink womb filled her vision; it felt so weird for it to be hanging off her in this way. She was accustomed to feeling her foal curled up in her really any way but this, until now; it pressed deeper at her lungs than it normally did, and the act stretched parts of her she hadn’t stretched in months. Anypony who were to look just over the counter would be seeing a plump, pink posterior bizarrely exposed by the tail bunched between it and the counter. She lately wasn’t so flexible, so she gave her belly a kiss before bouncing her rump from the counter, landing her hindhooves on the wood floor, and finally recovering her standing position. The little one protested, but all of the twisting and turning, along with gravity, led the kicks outwards, which she didn’t much mind in comparison. Carrying Earth pony foals usually led to bruises, from their hard kicking, but she didn’t want to add a broken rib to that. “I love doing things the easy way.”
