There's always something going on at St. Henny's High School. With so many naughty troublemakers around, things are bound to get out of hand!

That's exactly why a group of horny girls get into a spot of bother, but receive a most challenging homework assignment as 'punishment' - they must explore their darkest sexual urges!

Come and see how the girls achieve these feats now!

In the third update, watch Mia use her charms and homework pretext to seduce a regular at a gym and explore things she hasn't experienced before. And Effy can't possibly stop on seducing just 1 teacher, can she? The little troublemaker has a special knack for getting into problems. Who knows where that will lead her?


The purchase includes all future updates! The next update will be out in February.

Currently features:

  • ~1000 renders
  • ~ 100 animations
  • 43 bonus images

Tags: Female Protagonist (mainly), Male Protagonist,  Teen, Vaginal Sex, Lesbian, Humiliation, Group Sex, Exhibitionism, Masturbation, Voyeurism, Teasing, Blackmail, Small Tits.

Hello DK! Just bought this game to add to my DK collection n was not dissappointed whatsoever. Luved the fact that you created this game with all of our favorite young ladies from past games including some new cuties to enjoy. Thank you for including 1080p animations for my slower laptop. 

Gf n I truly luv ur work immensely. 

Big Hugs and Much Love from the both of Us. 💕


Always great to hear from you guys, thank you for the great support! We'll do out best to continue delivering :)

got a question. I am a big fan and I have bought most of the games you have. I know it was stupid but back then I didn't know I will want them. Does it makes sense for me to buy a bundle when having most of the games in it bought already?  Thanks

I guess it depends, you do the math if it makes sense to you :)
You can check our subscriptions, all games can be had with a higher one, but the cheaper one will also give you a number of games you may not have yet.

We will also probably have a sale down the line. Anyways, appreciate the support!
