I remember there was a lower res version of that demon girl with a rapier with the d20 motif, shame that was before the J7w pixiv purge ugh...anyway.

https://inkbunny.net/s/2182964 page 009 - 014 Looks like another missions of our unlucky ninja duo failed thanks to a bad roll of Onyx. This time they didn´t only got captured, but also got turned into belly dancer doing "special services" too. Tamina actually turned out to like her new life better then beeing a sneaky ninja. And the idea of beeing a mother makes her quite happy. Onyx on the other hand hates all of it. With her belly this huge fighting is pretty much impossible. She´s probably carrying at least twins or triplets in there. Guess her next escaping attempt has to wait until the babys are born. ;3
https://inkbunny.net/s/2396387 page 015 - 019 Tamina´s mistress Onyx took her to the monthly slave market and got a new pet for herself in the form of a poor dog woman. The young frog girl is tasked with holding the leash on the way home. She does her best to be nice to the obvious ashamed girl, but somehow Tam can´t shake off the idea that beeing a slave suddenly doesn´t feel so bad anymore. At least she doesn´t has to walk around naked and on all fours all the time. Especialy in her current condition.
A D20 refers to a twenty-sided die. They are most commonly used in tabletop role-playing games like Dungeons and Dragons, or Pathfinder. When a player wants to do almost anything in these games, they roll a D20. Rolling a 20 on the D20 is a critical success, usually guaranteeing a favorable outcome. Conversely, rolling a 1 on a D20 is a critical failure, usually guaranteeing a very bad outcome.
