If losing weight were easy, there wouldn't be an obesity epidemic. A man with a partially shaven face brought in a package of mix drinks and a workout video, the package addressed to him, Charlie.

Charlie's doctor repeatedly told him he should try to lose weight. He wasn't 'that' fat. He weighed average as far as an American went, but that was the problem when the average American was obese.
Charlie opened the box and found a large container of shake mix, and the workout DVD. "Just watch once and you'll see instant results." He said to himself, the same promotion that they said on television. He doubted that it would ever work the way it did on television, but the promotion said that if it didn't produce any results after the first day, there was a 100% money back guarantee. Not that Charlie expected to get his $20 back.

Charlie mixed a portion of the powder into a glass of milk and drank it. He figured he could just start the exercise tapes later. "Ugh." The drink turned the milk chocolate, but it wasn't a good tasting chocolate. He swallowed down the whole glass and let out a soft belch. "Blech. Well, I guess none of these protein drinks ever tasted good."

Charlie set the drink down and glanced at the workout video. He decided to pop it in his DVD, if only to see what it was about. He felt a small shiver down his spine from the drink, but he thought nothing of it.

The video oddly didn't even start with any sort of introduction or title screen to hit play to start the workout. The workout simply started with a bull anthro on the screen, a red furry bull anthro whom was very much naked, and very much well endowed.

Charlie blushed at the sight of the bull. He forgot for a moment that he was even watching a video. "Is that...is that CGI?" He had to admit, the DVD designed the effects on the bull very well. It really did look like a furry bull anthro with a cock that swung to his knees.

"We're going to start with an extremely basic exercise! Get up, and then get down on the ground!" The bull commanded as if he were an army drill sergeant.

Charlie jumped at the order. He found himself quickly obeying the bull. He went from the couch to the carpeted floor in front of him and placed his hands on the ground. He took the same position the bull did, and then paused as he realized what he just did. "Wait...I was just going to look at the video. I wasn't actually going to work out." He told himself.

"Now push yourself up! Then back down! Up! Down! Up! Down!" The bull shouted.

Charlie found himself obeying the bull. He didn't know why he was obeying the bull; it just felt as if it were natural to do so. He pushed his body up, and then down, and then back up again. He swore he felt his clothing shift underneath him, but he barely had time to look as he followed the bulls' instructions.

"Now, we're going to stop, and you're going to take your shirt off and look at your new and improved body! It's hardly a start, but it should be enough motivation to get a maggot like you doing a few more exercises!"

Charlie sat up and panted heavily. He swore he must have done a good twenty pushups. It wasn't an amazing amount, but it was large enough to tire his arms out, especially since he rarely did that exercise to begin with. "A longer break than five minutes, I hope." He sat down with a thud, and then pulled his shirt up as the video requested.

Charlie's eyes grew wide at the results. He wouldn't describe himself as fat, at least not normally, but now he had a visible amount of muscle showing. The muscles weren't amazing, but his body had a toned look, whereas before he was chubby. "Talk about instant results." He gave his stomach a poke, as if to confirm the muscles were real.

"Those muscles are one hundred percent real! If you took a drink of that protein mix, you'll see instant results! The more you drink, the more you'll change, so drink up, exercise part of your muscles, and watch the results!" The person on screen said as they took a swig of a drink themselves. Based on the color of the drink, one could easily assume it was the protein mix.

"Talk about advertisements." Charlie figured that he'd drink it all, and then they'd encourage him to buy more for an absurd price. Still, this was the first drink he ever had that showed immediate results, and he meant immediate. Unable to help himself, he had another swig of the protein mix. There was a 'lot' of it to use after all.

"Now, let's do some squats! You don't need any exercise tools for this besides a wall! Just follow my lead!" The bull leaned against the wall and proceeded to move in a sitting position, and then back up. "Do some Kegels while you're at it! Act as if you're holding back pee for five seconds, and then relax."

Charlie sighed. "Going right back at it like a coach usually does, huh?" Charlie worked out just as the bull instructed him to. He even did the strange Kegel exercise. He felt his cock tense up as he pulled his muscles back, and then he relaxed. He pulled in the muscles again, and then stopped. He felt his cock slowly grow hard as he did these exercises, and his muscles swelled even more. Depending on the exercises, he grew muscles in that area, much faster than a normal person would develop muscles as well. He couldn't complain about growing muscles so quickly though, but his arousal was becoming an issue.

"Now, with all these new muscles, I bet you're getting aroused!" The bull reached down and pulled off his clothes to show off a massive cock. "We're going to do another exercise! You may not be familiar with this one. Rather, you might not be familiar with it as an exercise. Put your hand on your cock and stroke, just like this!" The bull wrapped his fingers around his shaft and stroked his cock.

Charlie couldn't believe what he was seeing. He swore the video wasn't mature rated. Still, since he had a body that was a step beyond toned, but not quite muscular as of yet, he figured he could comply. "If it gets my cock bigger, who am I to complain?" He stroked his shaft, and shivered as he stroked. His cock felt much more sensitive than he remembered it being. "Ahn...f-fuck. This feels good."

"Keep stroking! You might find yourself orgasming sooner than before, but don't let that stop you. Don't let the pleasure stop you. Keep stroking, even during orgasm." The bull encouraged.

Charlie had a brief thought that the bull should be orgasming if he was right. Before he could think too much of that though, he felt a surge of pleasure rush through his body. He let out a quivering moan. His legs locked up as he felt himself orgasm. His cock came bit by bit, and he kept stroking it. He could feel his pulsing, throbbing cock shrink in his grasp, but he kept going. Once he finished his orgasm, he panted heavily. He noticed the bull didn't orgasm once at all. "Ahn...at least...it should...it should be bigger...even when flaccid, right?"

Charlie's body shivered again. He looked down and saw his cock hadn't gotten bigger. In fact, it was even smaller than it was before he stroked it. "H-huh?" 

"Now, I'm sure you noticed your cock is much smaller. Don't worry! This is all part of your bodily transformation! You just keep stroking that much smaller cock and keep squeezing. We have to milk all that cum out of you until your cock changes into a cunt!" The bull instructed. "I can't show you that, but I'm sure you know how to work it!"

Charlie found his hand stroking his now flaccid cock and squeezing it. He let out a moan as cum squirted out from his shaft, as if he were milking from the nipple of a cow. His testicles tensed up and then retracted with each pull, and they became a bit smaller with every squeeze. "Why...why can't I stop?" It felt 'very' good, but he was milking his cock into nothing. He had to find a way to halt himself.

"Let's make sure you cum out more than just your cock too. You must get rid of that humanity of yours! Squat down like so!" The bull squatted. He spread his legs wide and placed his hands on his knees. "And have a strong orgasm! Lose some of that masculinity for the cow deep within you! Let her out!"

Charlie expected to become as muscular as that bull, not transform into some weird cow! His body went along with the bull, as if the bull were the alpha and he was the beta. "How am I supposed...how am I supposed to orgasm if I can't even touch it?" He felt his cock continue to drip cum, and the pleasure it brought him. His legs felt tired, and his body hot. Sweat dripped down his body as the muscles stayed, but they were nowhere near close to the bull's own. Horns popped out from the top of Charlie's head, and his skin turned pale.

"Just let it happen. You made yourself orgasm well there! You'll slowly lose your humanity. Just keep working on those Kegels. Milk those two nipples just above your crotch too!"

Charlie wondered what the bull meant. He reached down and felt two small nubs that felt as sensitive as nipples, but he was too afraid to look down to see if they were. He found himself giving the nipple a pull, and he let out a deep moan that, while it sounded deep, also had the hint of a bovine, feminine moo to it. Unaware to him, two more nipples appeared on his crotch and slowly pushed outwards. A pink sphere developed behind it as the beginnings of an udder.

"Yes, you are a strong cow and produce excellent milk, but you submit to your bull master, do you not? You exercise and work those muscles. You get big and strong with plenty of healthy milk!" The bull encouraged.

Charlie swore he only had a little bit of that massive protein mix. To change him this much through modest exercise was unbelievable! Then again, to transform him 'at all' was unbelievable. While most of his skin continued to turn pale, black patches appeared on his body. His breast grew out, as did his nose and mouth. "Got to...got to stop. It feels so good though. So hot. So sexy. Such a beautiful bull." Charlie let out another moo. His cock retracted into him, along with his testicles and formed a vagina between his legs, changing his gender from a he into a she.

"That's it. You must be a woman by now. Just a little bit more and you'll become a cow. Experience your first female orgasm and finish your transformation into a strong bovine!" The bull encouraged.

With Charlie's gender changed, her skin converted to hide, her feet hardened and turned black, and a tail pushed out to form a bovine tail. Her tits now measured at least a D cup, and her new udder that she couldn't stop milking was just a bit bigger than that. With another deep bovine moo, one that sounded very feminine, she orgasmed with a moan. Her legs trembled, and she fell on her toned ass. Her transformation was finished. She was now a cow anthropomorphic creature, and a strong one at that.

"If you want to transform back, just buy the remaining ten tapes. If you want to just become a male bull, just buy five. All for a low cost of $99.99 per tape. Or a subscription to Myu's Patreon."

Charlie groaned as the tape concluded. She collapsed onto the ground as her newly grown tits and udder leaked milk. Even her cunt leaked a clear feminine fluid from how turned on she was. She was in control of her body once more, and she let out a heavy sigh. Of course, she had to buy more tapes. However, she 'could' change back, at an extremely expensive cost anyways.
"Fuck capitalism." She said with a quiet moo.
