10 CG (134 Variations)

Initially, I was thinking of making this post in the BE section. Mostly because of the strong focus on Isuta's bust going from flat to an 118cm L-cup bust when she transformed. However, she also looks like she physically developed elsewhere, most notably her horns. I can't really tell if her limbs grow as well, but the protagonist made a comment about her changing back into a lolikko toward the end, so I'm not in the mood for anyone to comment on whether this is BE or AP.

Anyway, this is the sequel to another story involving the protagonist being visited by his older sister, Asute, who happens to be the princess of Makai. This time, the protagonist is visited by his little sister, Isuta, who pretty much raped him until he force fed her his sperm which caused her to transform into a less dominating personality.

Content-wise, these works are quite skimpy on CG (Well, there are a lot of variation CG). Basically these companies are hiring scenario writers and illustrators to do very short games depicting a wide variety of scenarios and fetishes using the same system and a small cache of music pieces they share (Meaning it's pretty easy to get bored of the music if you buy more than one of these). There's some other works by them with BE, futanarika, multiplication among other things as well, but I didn't buy them so I don't know anything really since I only bothered with the titles by illustrators like Morishita Futaba and Miss Black...
