Outer Nethertech International-Marikos revenge experiment (The fall of the Family)) (Patreon)

Here, we are at the final part of Mariko's revenge experiments. We saw how the mother degenerated into a Futanari beast. Now, we see the mind-altering transformation of the daughter and the big finale.

Mariko gets 2 new powerful servants, and you get 2 futanari giantess to watch.

What a win-win situation!
