An unwitting man buys another item from the MILF Co line, the Teen Tea Infuser

Steve McKenzie wasn't aware of what he'd picked up. In his mid-30s and a desk jockey in a boring bureaucrat job, he was socially awkward and kind of nerdy, so he didn't have a lot of friends. So he spent a lot of time, sometimes browsing the web, sometimes aimlessly browsing local stores and flea markets.

He'd taken home what he thought was a machine for making tea, but was actually the lesser known cousin to the MILF Brewer, the Teen Tea Infuser, or TTI for short. It had similar effects to the MILF Brewer, making a drink that when permanently imbibed turns the drinker into a woman. But unlike the MILF Brewer, the TTI transforms the user into an attractive (and usually curvy) woman between the ages of 18 and 25. As usual, they'll possess a heightened sex drive and almost supernatural allure, with the extent of the change depending on the strength dial, going from 0-5, with different additions to the drink having different effects.

Steve took it home and unpacked it, whistling away to himself as he set it up and tried to figure out how it worked. He didn't have an instruction manual, of course, and couldn't even Google it as the brand name had peeled off of the plastic siding. MILF Co always did go for cheap stickers. The basket opened up, and clearly steeped for a level of time denoted by strength... and the remnants of a surviving label pointed to the basket with bold letters proclaiming 'ADD INGR////ENTS FOR //LDER FFECTS'

Maybe he should just try it. Steve unwittingly set the strength dial to 3, Complete Reality Alteration. He rummaged in the cupboards, looking for tea leaves, before finding some old herbal tea in the back of his cupboard. There were a few unlabelled sachets, and he pulled them open, sniffing them, setting aside the ones that seemed too stale, and poured them into the machine. The manual for the TTI was fairly extensive, but made of cheap easily torn paper, and faded quickly. But if he had had a legible one, Steve would have been able to figure out his fate in advance. Watermelon tea or full fat milk alone would have given his new body fairly sizable breasts, but having added both, his breasts truly would be watermelon sized. One sachet contained acorn and lavender; acorn had the side effect of ensuring the new reality would be his 18th birthday, truly making the years fall away, whereas lavender would give the urge to be a girly girl. The final sachet Steve 'experimented' with was thistle tea, which obviously turns the drinker Scottish. Hell, he'd have known not to put a little sugar in, for sugar made the drinker fairly sweet... sweet interpreted as bubbly, wide-eyed and gullible.

The machine whirred and hissed, steam rising from it until after about 5 minutes, it let out a bing noise and with a sluicing sound decanted a strange pinkish coloured liquid into the cup. "Huh, this looks odd." Steve raised it to his mouth and sniffed it. It smelled good enough, sweet and intoxicating. But it certainly didn't look like tea...

Steve swallowed a mouthful of it and cocked his head. It tasted very good too, incongruously sweet given he'd only added a little sugar and these were bitter herbal teas, but it went down a treat, and in no time, the cup was drained. It felt soothing, relaxing, so relaxing that he let himself slump onto the sofa, and just take a little nap...

There was a hammering on the door, urgent, loud. A woman's voice yelled from behind it. "Caitlin McAllister, are you up yet? For god's sake, you've got to get up for school, even if it is your birthday!" Steve started awake, starting out of bed. He stumbled for a moment, pulling on his glasses, looking for his dressing gown, pulling it on to cover his huge breasts, when he realised... hold up, since when did he have huge breasts?

He looked at himself in the mirror, and the 18 year old face of Caitlin McAllister looked back.

His brain felt odd. With every second he felt Caitlin's life seeping in. It wasn't that he didn't know he'd been changed, he did, but it was like... all of reality had changed, history had changed. Parts of who she now was were seeping in. Which is how she knew she had 30J breasts, and was just eighteen this morning, and that had been her mum calling her down for breakfast. Her dark-red hair was tied up messily on her head, and apart from her humungous knockers and wide hips, she had a fairly slender frame, a total knockout.

Caitlin's hand crept between her legs, a little tingle of pleasure surging outward from her sensitive pussy. Ooh, this'll be nice to play with! Steve thought.

"Caitlin!" her mum called again.

Ok, so, something had clearly left Steve as Caitlin. He didn't know what, not having linked it to the suspicious drink yet. After all, magic wasn't real, and certainly not in a domestic product. But this did still leave him as a bodacious eighteen year old babe. Should he try to find a way back? Should he see what her life is like?
