Yes, Headmistress by bbbs Rated: R

[Reviews - 19]

Summary:

The headmistress at Byron's new school is massive, vuluptuous woman who towers feet above even her tallest students and staff. As if this wasn't enough to make Byron nervous, when she looks at him, he notices something in her expression that makes the hair stand up on the back of his neck. It's too bad he's required to spend so much one on one time with her this year...

Sorry to hear about everything going wrong all at once. I've been there and it can be very frustrating. Anyway, I hope everything is well, or at least better now.

I'm incredibly glad to see this back, it's seriously a great story.

You're good at writing likeable characters, and I find Byron a lot of fun. His interactions with other characters always feel somewhat real and relatable.

Hope to see more!

Smells like Marriage by Divediveburners Rated: R

[Reviews - 26]

Summary:

Andrew is a simple office man, seeking a hassle-free, organized life. A marriage to a brash, hygienically-challenged giantess proves to be an imposing situation. Yet, in a way, opposites attract, and Andrew finds that his devotion to his marriage, and his wife, outlives his own personal sense of cleanliness.

This is an episodic tale of fluffy one-shots, of differing scenarios Andrew finds himself in.

Previously called "Welcoming Home".

I used to reread the first chapter of this story all the time when you first uploaded it and I'm so glad you continued it.

Caitlin and Andrew's relationship is really fun and she is a great giantess, outwardly and inwardly.

Loved that moment where she slapped her palm against the wall to scare him haha.

Hope to see more of this!

Author's Response:
I aim to keep the relationship fun. Hopefully more developed and nuanced in the future, but still fun. It's funny, I originally wrote the "Welcoming Home" oneshot because I was starved for some sweaty armpits. I remember there was a story where a giantess had an entire city in her pit, and "Sweat and Tears" had a top tier armpit scene in the last chapter. There's more on on this site, I believe, far more, but people tend to be more foot-focused.
As Tolkien said, however, "the tale grew with the telling."
More will come, though I'm not sure when. Glad you enjoyed it, and thanks for the review!

Author's Response:

Thanks for the feedback man, it's very much appreciated! I've definitely got plans for Rachel to be more playfully cruel/dominant with her "clients" and for Jessie to be her gentle/hesitant counterpart.

I remember reading this when it first came out and I loved it. Recently went through it again and fuck man it is so good.

Super well written and the dynamic between Koji and Rachel is top tier as far as gentle femdom goes and both characters are just really fun in terms of their personality. It's inspired me out of a bit of a rut so I appreciate it.

I know this came out a couple of years ago now, but it's so good I just had to drop a review upon my reread. Thanks for writing it!

I dunno about a full on spin-off, but I could easily see a one off or something at some point.

@TomSpeedy

Accidentally deleted your review, here was my response though.

Thank you!

I really tried to make Casey a more realistic (hopefully lol) cruel giantess instead of having no reason behind it, so I'm glad it's coming off that way.

Looks wise Casey is vaguely based off my girlfriend, but personality wise, let me just say, I'm glad to not know anyone like Casey hahahah.

Susan will come along eventually, maybe in a couple of chapters, who knows. Casey seems to be a bit in the know, but maybe not fully.

Yeah, so that's what she was saying in this chapter, that Drew is the first tiny that she's actually gotten.

Glad you noticed that, I tried to make it seem like Drew was smaller than an actual human and Casey would be a giant compared to a normal sized person, so those kind of tendencies change.

I know how you feel when it comes to mental health and writing erotic stories. I tend to find myself wondering why I'm wasting my time on this stuff when I could be doing something way more productive, something that actually serves to better my life. Especially when feedback can be so scarce at times, it's not like it's necessary to validate your own work but it's nice to have y'know.

I used to be all about smut when it came to stories on this site, but I've come to really appreciate these more human takes on a shrinking situation. Stories that delve into a complicated relationship between characters and how they're affected by some convenient size magic lol.

As for the actual story. It's fantastic. Jeremy's childhood was horrible to read about and Elyse's reaction was intriguing. I really loved how heart-warming their interaction became. I'm a bit of a sucker for little cute moments in stories, so I particularly liked their brief back and forth over not being able to swim and the fact Jeremy didn't know what a sweet potato was.

The build up of our characters and their budding relationship is described realistically and was honestly pretty moving at times. You're a really talented writer who can paint a vivid picture and this stories proves that.

It sounds like you've come to terms with this all though and I completely agree. Writing these stories is a fun outlet and I justify it to myself by saying I'm 'practicing' for my non-erotic writing.

I'm rambling now though in an attempt to procrastinate uni assignments so I'll end with this. Thanks for reuploading this, I missed it the first time and I'm so glad I got to experience it now.

Author's Response:
You've got no idea how much that praise means to me. I'm totally humbled. As far as seeing this writing as practice, I completely agree. It's also the ease of getting a piece out to a specific demographic through this site while having access to immediate feedback, as there seems to be greater demand for well-written stuff in smaller communities.
I'm really glad you appreciated the small bits of character details. I'd definitely love to experiment more with heavily character oriented stories. Who's to say that one of the stories you write here won't evolve into the next bestseller? You know 50 shades of gray was a Twilight fanfic before the names were changed and it was published on its' own? You never know what could happen.
