#1 of Greentext

This was all originally written all in greentext format. It made the later sections have a weird flow with dialogue so I've rewritten all the sections after the first. The shrinking idea is shamelessly borrowed from shrinking girl green I read on /d. Saving this with all my other greens from the pastebin purge.

Chocolate takes you out to meet her macro friends. One of them is a 120 foot tall svelte otter girl who is too nervous to hold you in her hand. The other is a 35 foot tall red squirrel girl who gives you crazy eyes. Red squats down next to you and says "I used to have a stuffed bunny toy the same size as you."

They start pouring drinks and talking. Chocolate bunny tries to give you a sip of her drink and "accidentally" tips you into the glass. She excuses herself to bathroom to clean you up. She tosses you into her mouth and sucks the sugary drink out of your fur. "Its dangerous for you to taste so good" she says with a mischievous grin. She removes your clothes and leaves them to dry. She walks back to her friends with you naked and tucked into her cleavage.

The otter girl is embarrassed for you and chastises Chocolate. Red climbs up to the counter and pulls you out of Chocolates boobs without asking her. Red brings you in close and whispers so that only you can hear "I had my first orgasm grinding on Mr. Bun and always wanted to try the real thing."

Red takes you into the Otters bedroom and shoves you onto the giant pillow. She starts to lick your naked body and give you head. After a bit you cum while staring into her intense green eyes, she swallows and says that its her turn. She stands over you and pulls up her sundress revealing that she wasn't wearing anything underneath. Red squats directly on your face, and you try your best to stimulate her. She uses her hand to forcefully shove your head into her already damp sex. Your hands grip her buttocks as she starts to establish a rhythm. You're scared you cant breath under her, but soon her legs spasm and you can feel her whole body quake. She rolls off and curls around you with her tail. You gasp for air and she tells you that you were better than Mr. Bun. She idly scratches your chest as you catch your breath. Red carries you back into the main room snuggled up against her petite bosom.

Chocolate winks at both of you as you enter the room. Otter girl appears to be tipsy. Shes complaining that being a macro and a student AND an athlete doesn't allow her to "socialize". Red climbs up on the counter next to her, unnoticed. Otter confesses to chocolate that shes never even had an orgasm. Red kicks otters forearms and holds you up to her. Otter looks down at you and embarrassingly tries to sputter out some kind of excuse. Chocolate takes you from Red and shoves you into Otters free hand and assures her that it'll be fine. Realizing you don't have a say in any of this you look up at otter approvingly. She looks at you for a moment, then slams the rest of her drink and folds her other hand over you.

Otter undresses in the low light of her bedroom. She brings you up to her face, still gently cradled by her hands, and tentatively sniffs you. You take the opportunity to lean in and give her a kiss on the nose. She gets flustered and starts to call it off. You tell her she can do whatever she wants, she has complete control. You also suggest that she lie down and relax. She does and her hands naturally fall to her breasts. You start kneading the soft flesh beneath you. You find a nipple as big as your head and start to massage it. It gets warmer and engorges, you look over and see her playing with her other nipple on her own. You jump down to the valley between her breasts and start to walk south. Her stomach is not like the fluffy bunny bellies you've gotten used too. She has defined abs and slick fur that you rub your feet into as you continue on. You've arrived at your destination and start to climb down.

A giant finger lightly presses on you. You look up at her face, she seems hesitant at first, then her finger lifts. She spreads her lips apart and you enter her. Shes already so wet just from this light play that you start to massage her folds. You feel her move around you as she starts to explore herself with her fingers. You've worked your way to the clit and grab it with both hands. She forcefully clenches up around you and rolls to her side. Disoriented, you aren't sure if you should continue. One of her fingers encouragingly presses into your back. You push yourself deeper into her so that you can give her clit more attention. A finger is rhythmically rocking you as you place your mouth on the fleshy pearl. Everything around you tenses up and her fingers are pushing you harder and deeper. You scramble to get back to your position gripping whatever you can along the way. Another spasm clenches you from the chest down, shes using both hands now. Her middle finger is rubbing on her clit above you, her other hand is pushing you in deeper still. You take a deep breath as you are forced into her. You feel her pulse, you smell and taste her, you grip her fingers for dear life. She shifts again and you are pressed on all sides. You can feel a moan echo through her body. Everything relaxes and you can breathe again, you pull yourself out of her. Shes lying on her front, you fall out between her thighs with her tail covering you. Otter goes to her side, she grabs you and brings you up to her face. She gives you a weak smile and fully rolls over, she pulls you down to her breasts to rest.

A couple more months go by. Blondie and Chocolate start to give you more space. The novelty of you being around must have wore off. You spend most of your weekends with the girls. Otter still gets flustered when she inevitably takes you to her room for the rest of the night. A short fall break is upcoming and otter has her last track events.

You found out how she competes with other athletes given her "advantages". The girls explain that there's a re-sizing ray at the events that allows macros, normals, and micros to compete. It only lasts for a short period of time so its not really useful outside of events like this.

Otter has taken to carrying you around in the cup of her bra when you all got out. You're taking a nap there on the way to the track meet. You wake up to some bright lights, in a changing room. You ask Otter if you're there yet. She immediately freaks out, and is so flustered she can't even say why. She walks into another room with two other giants and tells them she forgot you were on her. They scratch their heads saying the rays are only calibrated to work on macros. You suddenly realize what happened, the giants are not macros, Otter has already been normalized, and you're only 3.5 inches tall.

The techs assure both of you that the effects will only last 5 hours or so, though they don't look too confident. Otter finishes getting changed and carries you outside. Red and Chocolate are there, only now they appear more like 700 ft and 1600 ft tall respectively. Chocolate is struggling not to laugh, meanwhile red is fidgeting with her dress and looking at you. Otter has to go to her events and dumps you in Chocolates hand. Her paw pad is nearly a hundred feet across. Her head hangs in the sky like a planet. "Are you alright, honey?" she thunders.

Your response was rude enough that its probably best that she couldn't hear you at all. She passes you back to Red, who can at least still handle you with her fingertips. You get tucked in under her spaghetti strap on her collar to watch the events. Otter wins plenty of her competitions and you cheer her on even though Red is the only one who can hear you. The meet goes by quickly and soon Otter has changed back into her day clothes to meet up with the group.

She takes you back from Red and holds you delicately. Shes so apologetic about your situation that she barely registers the congrats shes getting from people for winning. You're lounging on her muzzle when the resize ray expires. The only problem is that it seems to have expired just for her and not for you. As she grows back to her old size you appear to dwindle away. Her old height is a gargantuan 2400 feet compared to you. You're perched at the base of her nose, so small that you are grabbing individual hairs an inch think to hold on.

Otter tells the others she can't even see you, she very slowly and carefully squats down so Red can look for you. The familiar but huge face of the squirrel appears above you, after a few seconds her eyes zero in on you, and she offers her hand for you to crawl onto. Otter is distressed that you haven't returned to normal. Chocolate suggests that maybe they should all just wait a few minutes more to calm Otter down. A few minutes later a very angry 120 foot tall otter is verbally assaulting the two technicians. They get their supervisor on the phone.

You can't really make out whats being discussed in detail, something about how skin contact with a macro can sometimes channel the rays into someone else. They said a mega-dose like that can causes a prolonged effect, between 24-48 hours. Otter is frustrated, but promises to not let you out of her sight until you're back to your old size. Chocolate gently suggests that otter shouldn't take you, since she can't hear you and can barely see you. Otter points out that chocolate is basically in the same boat. They both look down to red. "I can keep the micro bun for a day or two" she says with a worrying amount of enthusiasm.

Otter and Chocolate agree and say their goodbyes. Red plucks you up from her hand with her thumb and forefinger.

She says "I can't wait to find out for myself if what the bigger girls say about you is true."

"I'm not sure what you mean" you say cautiously.

She giggles. "The others have told me that you do your best work from the inside" she said as she pulled back the waist of her skirt. "Get comfortable" she said with a wink as you were dropped into her panties. Red spent the next day running you through a gauntlet of debauchery while you were in her "care". It started with her masturbating with you much like the other girls did, except she had the stamina for multiple sessions and would add toys to the mix.

She moved on to pressing you into her clit while she penetrated herself with a giant dildo. When she was done she stuck you between her toes and would walk around her apartment. She would let you go, only to press you with the pads of her feet and then curl her toes over you to pick you up. She shoved you under her tongue and refused to let you out until you had jerked off. She stuck you between her buttocks and went for a run. When she got back she used a band-aid to strap you to her nipple while she took a shower. As soon as she was done she forced you into another session of pleasing her. When she finally decided to go to sleep she simply left you stuck to her soaked panties and pussy.

The next day was more of the same and you grew concerned as the 24 hours mark came and went. She was getting pestered with text messages from Chocolate and Otter so she pulled back on her playing. You grew back to normal size the next night, while stuck in the same place as before. Though normal was still only roughly 1/7th her size. She took some additional liberties with you til morning came. She dropped you off, bruised and battered but alive, at Otters.

You had planned to spend the break with Otter and had only lost two nights to the accident. She still felt responsible for what had happened and wanted to make it up to you. She orders out from your favorite place for lunch. She snuggles up to you as you eat on her pillow. You have spent a lot of time talking to each other like this over the past few weeks, but you also enjoy just being next to each other in silence. Going out activities are limited for macros her size, she mostly goes for walks with you on her shoulder.

After getting back from your walk, she takes you back to her bedroom. Shes gotten better at taking the lead and starts by licking you gently. She whispers to you how much she missed you and how frustrated she was to put off her plans after the meet. Otter is on her knees on her bed, she wastes no time shoving you into her. You've become very acquainted with her anatomy and assume your preferred position. She leans back so that you aren't fighting gravity. You feel her tighten up around you as you intensify your attention on her most sensitive parts. She starts to cum and you are pressed on all sides even tighter.

Somethings a little odd, you're usually deeper in when she gets to this point. She must have been really anticipating this if shes coming this early. You pull yourself out and stand up. Looking around you realize somethings not right. She's smaller? No, the room and her are the same, you're larger. She props herself up on her elbows, the look on her face changes from bliss to surprise when she sees you. A few panicked phone calls later and you have a researcher from the size-ray company on the line. Its possible you are among a very rare group of people that experience prolonged paradoxical effects of the ray. He schedules a time to meet with you tomorrow, after confirming that you aren't infectious or a danger to anyone else. Being cupped in the hands of otter you both guess you are about twice your normal size. She playfully nuzzles you and says you're the cutest macro shes ever seen. She carries you back to bed so she can really test out your new size.

Otter takes you to your meeting the next day. It's a macro friendly facility, but its still weird that everyone is waist high to you now. The researchers spend an hour taking blood and giving you scans. The ray shouldn't have worked on you in the first place, and case studies like this are rare. The head researcher explains the situation, but the details go over your head. Essentially your body is "confused" about its normal size now. You are going to grow in discrete steps over the next few months. They advised you to avoid closed spaces and keep them up to date on any changes.

Otter takes you for another walk. Shes hopes they might be able to reverse whats happening to you. You say it might not be so bad if you two were closer in size. She gets embarrassed but says that's not what she means. "Being a macro is difficult and lonely" she said with a sigh. "I would love to have a more normal relationship but I know it's selfish to impose this kind of life on you." You two spend another night together.

The next day you go back to Goldies and explain the situation. She'll help you with transferring to the university macro program. But this means your classes are now remote and you have to stay at the house more. Chocolate is at the house too now that she doesn't escort you to school. Your larger size has caused some domestic troubles. Goldie says your new size is better for cuddling and petting, you spend a lot of your day in her lap or at her feet. Chocolate is fine with that so long as you spend your nights with her. She says that your new size is a better "fit" for her.

It always starts the same way, she'll already be in her tank top and panties then she goes looking for you. Sometimes you're able to convince her that you are busy with school work. But twenty minutes later shes fetching you anyways. She insists on taking your clothes off and it's basically the only foreplay you get. She lays down on her bed and takes off her panties. She then forcefully inserts you into her, feet first if you are lucky. You're pretty sure that it doesn't matter what you do so long as you thrash around and resist her. Once shes finished she'll lick you off and tuck you between her breasts to go to sleep. Sometimes you'll get woken up in the middle of the night as she uses you for a second time. One morning you wake up on her stomach with your feet sticking out from her tank top. You grew overnight. Chocolate rolls over and pins you under her breasts, she gives you a kiss on the forehead.

"All good things must come to an end" she says sleepily.

You're now around thirty feet tall. Red went and picked up some basic clothes for you. She said she would show you around town as a "real macro" and give you tips. You're still only chest high to her. She walks with her arm over your shoulder as she explains the rules to you. "Macro's are technically responsible for damages they cause, just like anyone else" she says in a matter of fact way.

"But no one wants to get stepped on" she says with a smile "They get out of your way if they know you're coming."

Some college students get off the sidewalk ahead of you as if to demonstrate her point. "Just keep an eye out for kids and old people and you'll be fine" she says with a playful side hug. It's still surreal to you, being taller than some buildings. You recognize some of the people around town, classmates and other people from school. You won't be blending into crowds anymore that's for sure.

She walks you down a park path. "I need to thank you for something" she said in an uncharacteristically serious tone "because of you I found out what I really want to do with my life."

You look up at her unsure of where this is going.

"I really like dominating guys, so I'm doing it professionally now" she says grinning again. Your expression is completely blank. "Check this out!" she says taking her arm off your shoulder.

She reaches under her opposite armpit and pulls something out from under there. A tiny wolf man is catching his breath between her fingers. "Can you believe this micro guy is paying me to do to him what I did to you?" she asks excitedly.

You and the wolf look at each other briefly. "Hey, I got an idea" she says rolling the wolf between her fingers "What if I pop this little guy in my mouth and we find a place in this park where I can blow you."

"Whoa, I didn't agree to any threesomes!" the wolf protested, but he was cut off as she balled him up in her hand.

"Quiet worm" she said tersely to her closed fist.

"What do you say big guy?" she asks of you playfully. You politely decline. Its been a while since you've seen Otter and you promised to spend the weekend with her. Red shrugs and pulls open her waistband, shoving the wolf into her panties.

"I'll walk you to Otter's place" she says "but you won't be this size forever. You might be too big to fool around after your next growth spurt."

"I'm always up for a challenge though" she says with a wink.

Otter appreciated that you are knee high now. She used to get so nervous just handling you and now she doesn't need to carry you around her apartment. Its very odd being "tiny" in her home and "huge" wherever you go around town. School is well into the winter break and you're spending most of it with her. Come the new year you get your next growth spurt. You're now 70 feet and change.

Goldie and Chocolate are disappointed. They both agree that you're no longer "cute" cute, just normal cute. You don't really get it but they are still supportive and helpful. You're more worried about moving out. You're sleeping on the living room couch and another growth session might not be good for Goldies house. You talk about growing again with Otter over the weekend. She seems to be getting frustrated as the conversation goes on. Finally she just asks you to move in with her.

"I don't want to impose on you" you say.

"You spend so much time here anyway" she says. She kneels down to hug you and says "I want you to stay here, with me."

A few weeks with Otter goes by. Your old school contacts you since they don't have accommodations for macros your size. Goldie helps you transfer to your current school, and get residency. Coincidentally the same day the paperwork is finalized you have your final growth spurt. You finished out at 115 feet.

The researchers confirm that you're done growing. You and Otter spend spring break getting familiar with your new size. You're still a couple "inches" shorter than Otter. She teases you about it all the time, which you usually respond with by carrying her to the bedroom.

You are planning a walking tour with her over the summer. It's going to be tons of paperwork to see the sights at your size, but shes worth it. The week before you set off you buy a ring. It's going to be hard to wait till the end of your trip to propose.
