I barely heard anything about this series, much less good, but really? If that's not porn I don't know what is.
It is effectively a "what if" scenario series about all the perverted things you might wish to see but know wouldn't happen.
Constant lesbian make out sessions, bsdm, implied orgies, tits of all shapes and sizes, gratuitous erotica, phallic symbolism galore, giantesses, people skydiving into said giantess's breast, etc.
There are so many fetishes in this series that it would take way too long to list them all. You honestly need to see for yourself to understand.
Wait-wait, is this really happening? In the anime itself? If yes, what episodes please?
Most recent episode (Episode 11). Uncensored version of course. Momoka straight up admits that she's looking to steal Mamori from Mirei, just to get back at Mirei for being the reason why Momoka "lost everything".
