So here's a bit of gift art from a longtime friend who I contaminated back when I used to get a lot more art of my characters switching bodies (something I should do again sometime).

FROM HIS DESCRIPTION:
Yep, finally a picture of Jam swapping bodies with Lauren Rivers! This is something I commissioned a while back that finally got done. In this pic, Lauren Rivers is pregnant and has decided to use that good old body-swap bracelet to borrow his body for the night. Meanwhile, Jam has to deal with weird cravings and the occasional kick in his belly. Doesn't sound like the most fair trade now, does it? The art was done by CMPony, who's a master of equines and body-swaps. Thus, he was perfect to bring this idea to life!

And I also have to thank for not only letting me use Lauren for this, but also being a good friend and inspiration. No joke, if I hadn't gotten inspired by Lauren's stories and the body-swap pics she commissioned, I probably wouldn't be a writer today. This was my way of thanking her, by featuring her in this little crossover. :) Also, I wonder how many people are going to see this post and immediately think I'm an alt account for Lauren Rivers? Maybe I should my avatar to her just to add to the confusion. XD Also, all characters in this story (with the exception of Jam) are the property of Lauren Rivers.

Anywho, I also wrote a story for this! If you like my work and want to see more stories like the one I'm posting below, then please support me on Ko-Fi!

Story:
"No, absolutely not." Stated Jam while angrily tapping his hand-foot against the ground. The anthropomorphic simian scientist had been invited over to a friend's house, one which happened to belong to the zebra known as Lauren Rivers. The striped beauty was clad in a semi-see-through purple dress, along with a pair of purple socks that hung off of her digitigrade feet. Her shiny black hooves remained uncovered, allowing the whole world to admire them in all their glory.

The zebra's long black mane was styled like hair and had blue streaks going down the sides of it. One may think this zebra was dressed up for a night on the town, but this couldn't be further from the truth! In fact, she was wearing her "nighttime" attire. The zebra couldn't go out to party even if she wanted to, all due to her rather large belly.

You see, the anthropomorphic zebra was seven months pregnant! Her rather wide stomach and maternal instincts made it impossible for her to go out and have fun. After all, she didn't want to endanger her or the baby's health! That's why she turned to Jam to act as a "babysitter" of sorts.

"Come on, Jam! I really need your body tonight!" Exclaimed the zebra while looking down at the three-foot tall monkey. "Lauren, I'm not switching bodies with a pregnant zebra! What if your husband finds out?" Lauren gently patted the monkey on his furry head. "He won't find out! He won't even realize that things have changed! Come on, Jam."

Jam rolled his eyes, he didn't really like what Lauren was peddling. "In any other circumstance, it would be a definite "yes"! The thing is that I'm not ready for such a commitment right now!" Shouted Jam, who glared up at the zebra. "Sounds like you're AFRAID of being a pregnant zebra! Here I thought scientists were brave and liked to experiment..." Lauren said while cheekily sticking her long zebra tongue out at the monkey.

"I'm not afraid of anything and I'll prove it! Give me the bracelet!" Shouted Jam, who proceeded to hold his grubby monkey paws in front of his body. Lauren smiled and walked over to a nearby table and picked up the ornate golden trinket. Taking the bracelet, she wandered over to the tiny monkey. Like a parent dropping a Mini-Snickers bar into a child's Halloween pumpkin basket, Lauren gently plopped the bracelet into the monkey's outstretched hands.

Jam took the bracelet and slid it onto his left wrist as Lauren smiled. "I knew you'd see it my way, Jam! Can't wait to see you with a baby bump!" Exclaimed Lauren as she proceeded to reach into her cleavage and pull out a small piece of paper. Jam raised an eyebrow in confusion as the zebra pulled the paper out of her bosom. It was an odd place to store a magic spell, but who was he to complain? This piece of paper happened to contain the "soul swapping" spell that works in tandem with the bracelet.

Lauren Rivers read the incantation aloud in a language that neither of the animals could understand. As soon as Lauren had read the incantation, the pair's vision went blurry. When Jam's vision came back, he found that part of it was now obscured by a rather large zebra snout! Jam let out a whinny of absolute joy, due to the rush of energy that came with being in Lauren's body once more. Jam always enjoyed being in Lauren's body, even in spite of it currently being pregnant.

Jam marvelled at the clean and well-groomed fur Lauren had, which was far more luxurious than the shaggy pelt his former body had! Jam's new fur-coat was comprised of black-and-white stripes, which befit the zebra he now was. Jam also now had a pair of shiny hooves for feet. It had been a while since Jam had worn Lauren's body, so walking around in hooves was a rather annoying experience.

Jam's favorite aspect of Lauren's body was that it was female! She had rather sizable breasts and wide hips, which were two of Jam's favorite things. Her least favorite thing happened to be large bellies, which is something she was now stuck with! Her engorged belly stuck out from underneath her satiny see-through dress, a reminder of her newfound pregnancy.

Jam immediately felt a kick from inside her massive stomach, much to her dismay. "Ungh, I immediately regret letting you coax me into this!" Exclaimed Jam, who proceeded to look down at Lauren. Lauren stood there in Jam's tiny monkey body while gently swishing her new prenhensile tail around. He wiggled his tiny pink nose and shot Jam a goofy monkey smile. "Come on, it's not that bad! It's just one evening, plus being pregnant is a good learning experience! You could should consider yourself lucky!"

"Yeah, lucky me! I get to have a bowling ball for a stomach and walk around like a constipated hen! Still, I'm confused as to why you'd want to swap bodies with me specifically. After all, my body has gone from 6 feet tall to a meager 3 feet!" Exclaimed the zebra while crossing her arms.

The monkey winked at the frowning zebra, "Simple: Your tiny body reminded me a bit of Grumpy Bear, primarily due to its new size. So, I thought I'd take it for a night on the town and give it a few body modifications to make it look like my favorite Care Bear! I'll have your tail docked, your fur painted blue, and the Care Bear symbol tattooed to your chest."

Jam glared at Lauren in disbelief, "You're joking, right? Please tell me you're joking..." Lauren snickered to himself while wiggling his fingers around like a supervillain. "Maybe I am, maybe I'm not! Guess you'll find out in the morning! Just don't be too GRUMPY about it if I do go through with it!"

Jam cracked a smile and chuckled slightly at Lauren's response. "You definitely have the crappy sense of humor associated with a simian, that's for sure! If you do get those body mods, don't spend too much on them!" The monkey scoffed at the zebra's statement, "Yeah, right! As if I could ever over-spend on anything! Don't worry, Jam, I won't make your bank account cry! Also, I put a list of food on the fridge that you MUST eat. A healthy diet leads to a healthy baby, after all. Also, be sure to act like me and be super nice to Chris!"

Jam then took a hoof-tipped finger and used it to scratch at her mane out of curiosity. "That's all well and good, but what if he asks me to make out with him?" Lauren smiled and pressed his filthy index finger against Jam's bulbous belly. "Don't worry about it, preggers! You can handle making out with a male ram just for one evening! That's even if he asks though, he may not. If you have any problems, just call Kate! I told her all about our swap in advance and she should be able to help. Anywho, I better get going!" Stated Lauren, who quickly ran over to the doorknob.

He leapt up and grabbed the doorknob, which was now much higher than he was. He gripped the doorknob and turned it, right before quickly opening the door. "See ya, Beachball Belly!" Exclaimed Lauren, to which Jam let out a groan in response. "Have fun and be careful with my body!"

"Don't worry, Jam, it'll be fine! Just don't get mad if it looks like an 80s cartoon character by the end of the night!" Shouted Lauren as she left the building and slammed the door behind her. Jam took her hoof-tipped hands and use them to rub her big belly. "Guess it's just me and the kiddo! Isn't that right, tyke?" Jam asked with a motherly smile as she looked at her big belly.

"Wait, am I talking to an unborn baby?! These darn maternal instincts are a kick in the head!" As soon as Jam said that, she felt the baby move around inside her. This immediately caused her pain and discomfort, resulting in her gripping her belly. "Oof! I'd rather have a kick in the head right now, it beats a kick in the belly!" Exclaimed Jam, who proceeded to walk towards the bedroom.

Walking was hard enough with hooves, but it was made even more difficult due to Jam's inflated belly. She stumbled about on her new hooves as her belly made it hard to properly distribute weight. It felt like Jam was wearing a fat-suit and high-heeled boots, which didn't make for a good combo at all!

Jam swished her now much shorter tail as she entered the bedroom. Jam sat her large rump down on the bed while patting her belly as she did so. The simple act of getting from the living room to a bedroom was a task on its own, so she thought she would just relax for the time being! It was a bit too early to go to bed, so Jam thought she'd just sit around on the bed and chill.

Unfortunately for Jam, fate had something different in store for her. She heard the front door swing open and someone stomp inside. "Honey, I'm home!" Shouted the voice, which unmistakably belonged to Lauren's husband, Chris. Jam began to sweat profusely as she heard the stomp of hooves moving towards the bedroom.

The ram shuffled into the room with his shirt already off, showing off his muscles in the process. Jam stood up and turned to face the ram, who was giving her some serious bedroom eyes. Jam uncontrollably eyed up the ram and admired his muscular body. He had beige horns, a long snout, and a pair of thick black hooves for feet. He was clad in a pair of grey pants and nothing else.

"H-Hi, honey!" Exclaimed Jam nervously as the ram approached her. "How is my favorite pregnant zebra doing?" Asked the ram as he skulked towards the zebra. "I'm doing fine, beloved husband!" Exclaimed Jam as Chris walked up to her. "That's good!" Exclaimed Chris, who proceeded to trot behind Lauren.

He moved in real close to the zebra's back and pressed up against her, causing Jam to blush nervously in the process. Chris than took his fuzzy hands and gripped Lauren's stomach with them. "Momma's got a baby in the oven! Ooh, I wonder what we should name him if he's a boy?" Asked Chris while gripping his wife's belly tightly.

"I-I don't know! Maybe E-Edward or S-S-S-Samuel!" Jam stammered nervously as the ram continued to grope her belly. "Those are all fine and good, but how about something simpler! I'm thinking one syllable, three letters." Stated Chris, which made the former simian even more nervous. Was Chris catching on? "H-H-How about Dan?" Asked Jam, hoping that answer would please the ram.

"I like that! Simple and effective." Jam breathed a sigh of relief at Chris' response, he was afraid that Jam was onto her. Chris then began to gently smooch Jam's neck, sending waves of pleasure all throughout her pregnant body. "Of course... Maybe a name that sort of rhymes with Dan would fit too. Such as "Jam"? Don't you agree?" Exclaimed Chris, causing Jam to let out a surprised whinny.

"You knew?!" Jam shouted, flustered by the events currently transpiring. "I didn't, but I do now." Panic wracked Jam's pregnant body, she couldn't believe she had spilled the beans! She was afraid to see how Chris would respond. Jam had only met the ram on a couple of occasions, but he had a feeling he wouldn't take kindly to a mad-scientist wearing his wife's body!

To Jam's surprise, Chris continued to gently smooch Jam's striped neck. "Of course, it also helps that Lauren told me earlier that she'd be swapping bodies with you." Stated the ram, who began to poke and prod the zebra's thick stomach with his hoof-tipped fingers. "Impossible! There's no way you'd know about it, Chris! The only ones who knew about it were me, Lauren and..." Jam stopped mid-sentence as a sudden realization hit her.

"...Kate!" Jam shouted as the ram nuzzled his face against hers. Kate happened to be one of Lauren's friends, as well as being an anthropomorphic snake. Kate was a rather promiscuous woman, one who liked to swap bodies and then knock up a few people in the process. "Bingo! Chris and I actually swapped earlier today, though I had yet to tell Lauren about it. I thought I'd come home and have some fun with a certain pregnant scientist!"

"Being a pregnant zebra is far from fun! There's stomach aches and the constant kicking, not to mention the craving of weird foods!" Exclaimed the zebra, who proceeded to pout. "It can be fun, at least if you know how to take your mind off of it! I know, how about you make out with your favorite snake-turned-ram for a few hours?"

"I only have one answer to that question..." Jam turned and then hugged her arms tightly around the ram. Her satin-covered stomach pressed tightly against the ram's bare chest, causing him to blush slightly. She then moved her zebra muzzle closer and pressed it against Kate's lips, kissing the ram softly in the process. The two soon locked more than lips as they worked their tongues into each other's muzzles.

They began to French-kiss each other; their tongues wrapping around each other like a pair of wet noodles. The two spent the next few hours making out with each other, enjoying their new bodies while doing so. Kate and Jam enjoyed being a married couple for the evening, despite Jam's heavily pregnant body.

Jam, Lauren, Kate and Chris all swapped back the next day. Afterwards, the four went out for some coffee and donuts. They reminisced about their body-swapping shenanigans and decided they'd have to do this again sometime, but it would have to be AFTER Lauren gave birth. While being a pregnant zebra was a good learning experience, it was something that Jam didn't want to repeat any time soon! After all, some monkeys just aren't meant to be moms!
