I can say you've overcome the first hurdle any author faces - you've kept me (your reader) interested.  This is a good start, and I'm looking forward to what comes next.

Seeing as your note at the end is asking for ideas and suggestions, I'm going to offer some criticism on the content above.  Please take it with a grain of salt - every author writes in their own way, and different approaches appeal to different audiences, or set different tones for their story, or suggest different levels of investment.

This first chapter leaves a lot of questions in the air.  This is a good thing; you want your audience asking questions.  It keeps them engaged, and anticipating what comes next.  There are two important qualifiers for this, however: 1) You want to prompt the audience to ask the right questions, and 2) you should have at least a basic grasp on answers to the important questions.  Questions like, "How did Jane and her friends end up in that horrible situation" are exactly the kind of question you want to leave your audience with to keep them interested, and something like, "They were pets who were stolen but managed to escape and were just trying to get home," is an answer you should have already answered for yourself when writing this chapter.  I write this so I can frame the big questions I have at the end of this first chapter.

1.  Why is Emily not surprised that Jane is tiny?  This is a very simple question, but the answer, and when you reveal it, have complex connotations, and could very well be a significant element of the story.  If tiny people are the norm, then the lack of surprise makes sense, and the answer to WHY they're the norm becomes important.  Are they a different species?  Are they victims of a virus/government testing/technology used illegally?  Or more intriguing, are they not common knowledge, but Emily is unsurprised because she is one of the few people who has met a tiny before?  For example (since I'm in the dark as to the true nature of tinies), Jane could be a borrower, in the theme of the classic folk tales.  Most people don't believe they're real, but Emily met one when she was a child.  Maybe something happened to this friend that inspired her to do good works, like working in a homeless shelter.  Maybe Emily did something to hurt this friend, and is now trying to make the best use of the rest of her life to atone.  The more clandestine answers are all things that could and should be revealed later, but if tinies are commonplace, that is something you should reveal to your readers early, so they are not surprised or disappointed later.

I know there's a ton of fabrication, conjecture, and smoke & mirrors here, but the point I am trying to make is that, when a character acts in a distinguishing manner (when they do something out of the norm), it needs to be informed by their past.  One of the most important things you can do is to be true to your characters - and whatever half-thought-up or 20 page detailed backstory you have for them - and to understand that if that character acts in a way that would be unique to them, or would break from common expectations, the reader will assume that the character is acting differently because there's something different about them.  To be clear, I'm not trying to make you second guess every action a character takes.  If Emily got a coffee with extra cream and two sugars, all that would tell us is that she doesn't like bitter tastes, she isn't averse to caffeine, and that she probably has a sweet tooth, but it's not story relevant.  The reason this reaction is important, is that the answer informs your setting, it potentially informs Emily's history, and it is an obvious departure from the norm because any of your readers would be surprised to find a tiny girl in the real world.  NOT being surprised highlights a difference from the readers, 'normal.'

2. Is Jane wearing any clothes?  No, this is not the horny talking - ok, not entirely - but the answer to this question actually informs many of the worldbuilding details that would similarly be informed by the answer to my first question.  If Jane is naked, that implies that tinies are feral / lower class / pets, or that something truly awful happened to her between leaving safety and being rescued, and I don't just mean the cat attack, unless it clawed her clothes off without hitting skin.  If Jane is wearing clothes, the kind of clothes inform further details of the world.  If the clothing is cobbled together, then Jane is either poor, or forced to make due in an unusual situation, or is better cared for than the average tiny.  If she is wearing scaled down clothing with factory or loom quality, then this implies further things about her lot in life, the status of tinies, suggests she was shrunk by technology, etc.  I suppose the point I'm trying to make here is that details matter.  You don't have to provide a ton of detail, but consider adding a few more considered details that can combine to more naturally convey information about your world to your audience.  

I'll list a couple more questions here without the long-fingered explanations, just to help you get thinking in case you haven't already answered these questions for yourself.

3. How did Suki end up as Shana's minion?  Usually socio-economic factors have a heavy weight in social interactions, so this development is definitely tied to something in Suki's character.  Did Shana's physical strength initially intimidate Suki, and learning more about Shana later eventually brought Suki around?  Is Suki a sub?  Does she have a foot or B.O. fetish?

4. How old are these college-age characters?  Dorms usually suggest underclassmen in an undergrad program.  Are Suki and Shana Sophmores (second year students)?  Is Maya a Freshman who plays with dolls?  Is Shana's whole family visiting?

I think that's plenty to be getting on with for now.  I want to again say to take the above with the understanding that I am not a professional author.  I'm just trying to help you think about your setting and characters when you write, and how to incorporate those elements into the story.  What you have here is a great start, but if your goal is improvement, then I would be honored to offer what context I can to help you improve.

Please retain the courage and confidence you had when you posted this first chapter to continue writing, and most especially, thank you for sharing your story with us!  I look forward to reading what comes next!

I missed that you uploaded multiple chapters, so I deleted my initial review and am reframing it.

You started us off with a cliffhanger chapter.  How delightfully cruel of you.

Congrats on another strong start.  You've got me hooked, and I'll be continuing this when I can eke out some more "free" time.

The premise is interesting.  I'm definitely getting "The Good Place" vibes, which I count as a good thing.  I'm curious to see how Renton's new size impacts the story.  I tend to find that below 4-6 inches, a tiny's direct influence on the outcome of a story quickly dwindles as their lack of size translates to a lack of agency.  I'm definitely looking forward to seeing how our deserving returnee gets along with his titanic saint of a wife.

I'm loving what you've done with this story, and I ca't wait to see where it goes next, though I'm getting the inkling it will be somewhere both sweet and sexy, and I'm all for it.

I'm pleased with how you've developed Renton throughout these chapters.  It reinforces him as a good, but still human(ish) man.  The small size has been both the expected challenge, and a constant driver for the plot progression, as it should be, but I'm pleased to see it hasn't entirely robbed him of agency.  Even if most of the events are acting upon him, his indestructibility allows his persostence to shine through in key ways, and the occasional presence of a dedicated, if selectively reserved full-size angel butler helps him act through her.

I'm loving that even in acting as an agent for Renton, Petra is also playing her own game, and she does so with a deftness that speaks to a significant amout of prior experience. If her short term goals are what they seem, I sincerely hope she is successful.

I can't end this without giving kudos to Molly's character.  The woman is dedicated, loyal, driven, and most importantly, loving beyond the pale, and I avsolutely love her character for that.  I'm also loving her more devious and assertive side.

So far everyone and everything is engaging, enticing, and a balm for the heart. Thanks again for writing this.  I can't wait to see how it ends!

This is a great start to the sequel!  Jackie and Lynn are great character achetypes.  Between Lynn's adventurous and outgoing personality wrapped uo in her tiny, two-inch body, and Jackie's tiny, caring soul in her lumbering big body, they make an excellent counterpart for each other.

Your supporting characters are great too.  Lynn finding a super-tall, half-japanese big to share a desk with in her first class is fun, but more than that, I love that Heather embodies Lynn's adventurous side, while Alena shares Lynn's creative and artistic side.  I see romantic potention between Lynn and either, and while I think Alena and Lynn would make a cute couple, I think Heather's height and active nature would make for a dangerous and wonderful pairing.

Melanie seems like a nice-enough touchstone for Jackie if she needs to get away from bigs to reconnect with people her size (spiritually), and Pierce has both drive and boyfriend potential.  Michelle is a character with a lot of potential, either to go the way of antagonist or villain, or else to figure out what the tinies need, and grow as a person.

I need to see more of Javi to get a good sense of him, but I'm leaning towards semi-aware player.

Your details are on point. Lynn's tiny pouch in Jackie's shoulder strap is absolutely adorable.  Four-limbed Spiders is a rockin' name for a mini-metal band.  I'm a little concerned that Alpha-Beta-Phi-Gamma's parties are literally killer for some of the tiny students, but that's likely me projecting all the sorority size stories I've read.  I hope.  Lynn diving to save her breasts cracked me up.  Great scene.

Now that my session has timed out twice, the review is done and I'm moving straight on to chapter 2 - everyone trying to side-track me be damned.

Ah, darn, there was one more point on which I meant to comment.

If I'm reading this right, the tiny desks are sitting on the floor at the front of the classroom.  This has me a little confused and concerned, as this places them in a prime spot to be stepped on, trupped over, or fallen upon by purpose or accident.  I imagine it might also hinder note-taking with the awkward viewing angle for the board.  I'm a little surprised there's not a modified big desk with tiny desks arranged upon it, both for visibility of the tinies for the bigs, and for the tinies to see the board.

Sorry for the seeming nitpick, but the practicalities of mixed-size society are one of those things that I dwell on when my mind otherwise goes idle.  I'm always curious to see what others come up with, and the reasonings for their approach.  I probably shouldn't expound on the various wall-mounted tubs / multi-angle showers / mini water parks I've thought about adding for a tiny resident in a big's shower, but somehow I come back to the subject most mornings when I'm getting ready for work.  At least my ideas are better than my singing...

Damn, my heart ached for Callie at the start of this chapter. Bringing Duncan in to help her cheat was silly, it was dangerous, it was daring, and worst of all, it had worked! And then it had all gone to shit... Duncan was missing, presumed dead (by Callie, sorta. Guilt sucks), and Callie had no idea what else she could do. I'm so glad Monica was there for her, to comfort her, and to comisserate, while keeping Callie from falling into despair.

The next scene with Callie was quite interesting as well. Holy crap is she handy! I mean, the bed was impressive on its own, but it sounds like Duncan has quite the setup here! And the pictures! Not just the effort in creating the framed photos, but the contents themselves are wonderful, or at least delightfully campy (Imminent vore shot? Check!). Duncan and Callie have such a wonderful relationship.

Swapping to Duncan's scenes, holy cow did you solidify Ada's nerd cred! From her Sci-Fi collection (I would have LOVED a Firefly bedpread when I was younger) to her Dune tee-shirt, it's obvious she's got the merch, but you really sold it with her socially awkward introduction and utter lack of conversational skills. That was totally me with strangers at that age. Well, strangers I wasn't meeting for a purpose. I actually think Ada did really well here! Kudos for letting Duncan carry the conversation!

And then the ice was broken, and that nerdy need to know surged forth. I absolutely love how well you characterize through action and word choice, and Ada's intro is a shining example of that. Oh, and the Cool Ranch Doritos and Dew? Classic!

But then she gets all possessive?! And here I was hoping the nerdy Browncoat would be a new, positive influence on his life, but nope, she straight up declares Duncan as her slave!  You betrayed my faith in you, nerdy Ada! But no! She doesn't really want to enslave him; she just wants a friend, and mirroring his reactions is about the extent of her social repertoire outside of talking about her Sci-Fi. Gah, my heart goes out to this poor, unassuming girl who just wants human interaction, not realizing the other party is a victim of abuse, with no real context about his captor beyond what she's shown him, and what he's seen from other giant, abusive women. She doesn't understand that Duncan's ability to stop their 'playacting' is something only she can perceive, and that even thinking of bringing it up is anathema to the abused tiny. She can't see or understand that his projected expectations mixed with her social anxiety and need for companionship have combined into a horribly toxic concotion of a social heirarchy, with neither feeling in control.

And then it gets so much worse (better)! Misinterpreting his stated fears as his desires, she doubles down and puts him in a degrading situation she thinks he'll enjoy, not understanding that... that, uh... that he actually will enjoy it, but will be very confused by his reaction. Damn, this was a great way to expose Duncan to some aspects of size play that would have been far less likely under Callie's care.  Gah, this was a perfect storm, and I absolutely loved it!

I'm also glad that when the truth came to light, Ada proved she was a proud Browncoat, and brought Duncan back to his found family (in progress). It was kind of Duncan to try covering for Ada, but perhaps a bit of explanation would have been the safer way to go, as shown by Monica picking up on Ada's pleased surprise.

I did enjoy that scene with Duncan and Monica. I'm proud to see her opening up with Duncan. I'm glad to have it confirmed she's not there for him romantically, but because she cares about him as a person. No chance of his growing relationship with Callie souring their relationship with Monica, at least not through direct jealousy. I hope they continue to stick together moving forward, even if there are some understandable reservations towards Ada.

Gah, I want to read another chapter, but it's bedtime. Great story, I'm loving everythong thus far, and I can't wait to see what comes next!

Hey, It Was Me?  I'm getting a little concerned here.  I'm down to one chapter left in a story that's Complete: Yes, and I don't actually see the end in sight.  You're too talented of an author to rush the ending, so, uh... I really hope that Duncan, Callie, and Co. are Okay at the end of this.  Nothing completes a story more completely than a permanent, biblical ending.

Alright, now that's off my chest, let's dig in.  I have to say, I shamefully did not consider Monica and Kristie might bond over their shared trauma, or rather, the trauma they imparted unto people undeserving of it.  I can see Kristie was actively trying to get Monica to do what she had threatened, but that does not absolve Monica of her responsibility, and I'm glad to see she knows this.  Still, I hate to see her suffer.  She did something unforgiveable, as has Kristie, but that doesn't erase the rest of their existence, and I am still rooting for Monica, and I've finally come around to rooting for Kristie too.  I totally want to see Monica & Kristie officially together at the end of this, with both of them working to smooth out their worst acquired interpersonal behaviors.  Especially Kristie's.  I'm expecting another comparative scene, where instead of Duncan, and then Callie trying to get everyone to trust Ada (which is suddenly seeming like a BAD MOVE), we instead see Monica trying to get the others to accept Kristie as part of the group.

And speaking of Ada... that uncomfortable-comfortable voyeur and really willing - super horny exhibitionist scene was hot as fuck!  Great use of a simple, but effective prop, both to turn Duncan into a finger fuck-puppet, and to finish Ada off by hanging him out to soak in Callie's saliva.  Start to finish, you really drew me in like a second voyeur in the room.  I love how well you teased Ada by including her in the action with Callie's attentiveness, without ever actually, physically including her in the sex.  Wonderful job.  10/10.

But then there was Ada's sexually-frustrated post FTB scene, and that stinger at the end.  Ada isn't telling our leading lady, nor her beloved finger fuckit, that there's more to the nanomachines than was presented at the start.  I don't think it's been framed by Catamaunt as a bad thing, else I expect Ada would have put a stop to it, but I do not like Ada keeping secrets.  Her judgement has been shown to be... rather naive at times.  I just hope whatever's going on doesn't hurt or separate our happy couple.  If that, "If another tiny man shows up on somebody’s doorstep, I’m calling dibs," isn't foreshadowing, then I'm actually the height I want to be.  I don't think it's Alyssia, but I have a sinking feeling for Callie.

And then there's that stinger.  Things are going well, and we already have one ominous secret threatening our happy, mixed-size couple.  Now Natasha's back in the picture.  May she find what she deserves.

Alright, I was able to read another chapter tonight!  

I like the tone set by the opening scene with Ada.  Duncan has been pretty accepting of his reality, and this is the first real look we're getting of him getting frustrated with his lack of physical agency.  I have a feeling that as he gets more intimate with Callie, this will be a more common occurrence - not necessarily Duncan losing his cool, but him coming up against barriers that he can't overcome with effort.

Great introduction to date-mode Callie.  I'm glad she's letting Duncan treat her.  For same size relationships this could result in a power imbalance, or cause friction over financials, but given the physical power imbalance, this is a good way for them to even things out on a different scale.  I'm glad Callie is conscious of the expense, but still willing to let Duncan treat her.  Also, poor Alyssia is the but of so many jokes that I'm glad she got some of her revenge last chapter, and got a great start to a passionate night of self-guided relaxation.  Also, the chauffeur's uniform is an excellent gag.  Absolutely love it, especially when she points to dinky Duncan and claims he "forced" her to wear it.

The car scene was delightfully spicy.  I know it's not the fist time you've used it in this story, but referring to her breasts as "girlflesh" still feels like a new descriptor to me.  It's self-descriptive, yet exotic, and I find it strangely evocative.  Absolutely love it, and I cannot promise I won't steal it at some point.  Still, that wasn't the only spicy bit, and Callie's unquestioning determination to "fuck Duncan's brains out" is a promise I fully intended to see fulfilled.  I was thinking to myself, "there better not be a bait and switch, dammit!"

The setting for the dinner is absolutely perfect, and I'm glad you managed to incorporate the entire cast into the date.  I'm also really glad that Ada is officially part of the group; she's not just physically present, but she's been accepted by everyone.  I also want to mention that I love Monica's use of manila folders for sensitive information almost as much as I hate what you do with them.  The teasing, the foreshadowing, the mystery all up in my face!  It is not okay!  Well, I mean, it makes the story and the reveal just that much better, so I won't count it against you, but know that those folders you use grant you great power.  Continue to handle such scenes with the great responsibility they deserve.

The discussion over the entre gave us a nice look at Duncan's past, but there's something going on with the Brenadines and Duncan that just isn't jiving for me.  You have dropped a bunch of hints and left clear indicators for this, so I feel like I'm just following along thus far with the slow unveil as intended.  If I had to make a leap of story logic forward, I would assume that the boy whose injury was blamed on Kristie was really injured by Duncan while he was with the Brenadines.  What's not clear to me is if Duncan is actually a blood relation of the Brenadines as well, but I see it as a possibility with the mysterious past before Duncan turned 4.  I'm also wondering if the injured boy (who I believe to be a Brenadine) or one of his family members targeted Duncan and Kristie as revenge for the incident.  That I do feel is rather likely, though I could see them being targeted as a matter of convenience, rather than the shrinking tech being developed specifically for Duncan and Kristie, and whomever else might end up affected.

Sorry, right, this is a review.  I'll take off my tinfoil hat now, and stop wondering if one or more of the girls will end up shrunk, with the new dynamic shaking up Callie and Duncan's relationship before the end.

So, right, where were we?  Oh, dessert!  Oh my god, the chocolate fountain was an inspiration!  I love Callie's seductively devious mind.  The two of them are an awesome couple, and this scene bares that fact to the world (or Monica at least) in all its sexy glory.  I love how well you direct Callie's use of her entire mouth, and how Callie makes use of her understanding that Duncan has a taste for rougher play.  Callie's power, the sensuous descriptions, and Duncan's perseverance made this scene hot as hell, but I think my favorite part was the confluence of a flustered Callie, a cool cat Duncan, and a wide-eyed Monica when she caught them in the act.  "Theck pleath" shall forever be associated with this scene.  Goodness, i was so happy with this chapter, that was a great way to end it, ready to pick up where they left off in the next chapt- er...

HOLY HANNAH, IT'S NOT OVER YET!

I may have yelled that aloud, much to the displeasure of my neighbor in the apartment next door, but holy shit did Callie and Duncan hit the bedroom running!  Everything from the action to the pillow talk to the full on couple's banter was on point, and I laughed my ass off at the reference to the couch incident (which I suspect was not a 1 time thing...)  Once again, I have to praise your graphic descriptions of movement and details, and I love how much agency Duncan had with pleasuring Callie, rather than being used as a masturbatory aid.  Great scene, 14 out of 10.  And then to end it with both of them satisfied, content, and best of all, at peace?  *Chef's kiss*  Simply magnificent!

Whelp, i just spent two hours writing an in-depth and thorough review for this chapter, only to accidentally reload the page and lose it... so I'm going to paraphrase here.

Great chapter, even if the last scene feels off.  Kristie feels both pitiful, and pitiable, and I don't feel like this style of punishment will do anything to curtail her behavior.  That's in part due to her constant outbursts despite clear and present danger, and from the mysterious file.  That Kristie would rather be raped than have that file's contents revealed points to a person who has done terrible things and not learned, or who is too absorbed in their self image for trauma to change her.

I'm glad Duncan reigned in Callie's semi-conscious attempts to harm Kristie, for which I can't blame the girl.  She has felt neutered against her own abuser, save for the last, near-disastrous act of defiance, and now her love's abuser is literally within her grasp.  I'm impressed some squeezing is the worst that happened until Monica got her hands on little Kristie.

The last scene, if decoupled from the story, was a very hot cruel-lite scene.  I really likes the casual power, the effortless dominance, the strain of Monica trying to carry on the conversation, Callie holding herself back from masturbating along to the amorous gasps and moans, and awakening to new desires for her interactions with Duncan.

However, in the context of the story, this scene feels off.  I can see Monica using Blackmail against the other employees in her company to keep them in line.  I can't see her using it to assuage her guilt over using her physicality to rape someone, even if that someone is an abuser.  Thematically, this story has been about decrying the evils of abuse in all its forms, including and even highlighting sexual abuse, and suddenly it's being used to justify Monica getting her rocks off.  I definitely felt off with this, like the part of a Season 6 Supernatural episode where we watch a major character do something totally uncharacteristic, and we haven't yet learned that they no longer have a soul.

Anyway, it was a solid chapter, with an objectively hot scene at the end that happened to feel subjectively off-kilter.  I'm really hoping I can read another chapter tomorrow night.

Screw it! The dishes will still be there tomorrow, and I can pull fresh clothes out of the dryer. *Smashes Coffee Mug* Another!

I'm always impressed with how well you maintain the sense of scale with each mixed-size interaction. You are detailed and descriptive, without undue verbosity. Our introduction to Dr. Catamaunt is a great example of this, be it through your description of Duncan's office, Callie's interactions with Duncan, or the Doc's reaction to seeing Callie from something akin to Dunkan's PoV. (BTW, I immediately Googled to see if the name has any historical / literary connotations... 0.0 Spicy!) 

So, we need yet another person to know about Duncan's existence? I immediately find myself expecting a cute med student, who... hmm, probably not a sweet girl - Callie is delightfully nuanced, but is closest to Deredere and Dorodere, likely ruling those out. Monica is close enough to a Tsundere to rule that out. Maybe a Kuudere? Makes sense for a med student, I suppose.

Oh my goodness, I love the mini house! Using rubber erasers for elevation would also serve for decent vibration isolation. Such a good idea! And I love the color scheme.

I'm also glad to see Callie moving past her mental hang-ups. The culture she grew up in forged those invisible chains of misplaced guilt and self-doubt; it's refreshing to see Duncan helping her to break free of them.

That being said, I'm concerned about how and when she's decoding to change things up. Her style isn't her typical comfortable clothes, but a reactionary risqué that may come back to bite her. Regardless of who is to blame for the gazes, wearing less fabric than Daisy Duke will draw additional attention, ans with Duncan with her, and less fabric in which to hide him, I expected this midterm to be very stressful for our dear Callie.

And... I was wrong? No, I was very wrong. I doubt her normal shirts had pockets, so I guess leaving her chest exposed gave Duncan more room to escape, but the impact her fashion combined with her physicality had on Slimewell was beyond my expectations. Well played.

As that confrontation was playing out, I loved that Duncan's mere presence was enough to bolster Callie's confidence. Couples that support each other, both actively and by extension with their passive presence, is what draws me to these stories. I absolutely adore this interaction.

Callie taking control at the end of the test was a little rude, but at the same time I'm glad to see her asserting herself in an environment in which she felt severely uncomfortable and timid.

That said, Brooklyn asserting herself over Callie's need for the restroom was just plain rude. If you need to talk, follow the poor girl!

But no, instead we get a panicked Callie, a missing Duncan, and a monstrously evil cliffhanger! *tucks the manuscript for Small Investments under a blank folder*

Damn, I've been reading off and on since about 3, and it's now almost 10:30, so I'm not getting a fourth chapter in today, but I'm so glad I took the time to read these chapters, and I'm chomping at the bit to read more. Do you think my boss would accept Evil Cliffhanger in a Fetish Story as a viable excuse for a last minute PTO request? I'm damn tempted to try it.

Anyways, this is a great story, loving the characters, and I can't wait to read more!
