On the one hand, I really do like this art-style quite a bit, and the ahegao expressions and heart-eyes are quite nice... The variety in the girls isn't bad either.
However...
Man, they blow through each one REALLY fast, can't savor any of them at all.
That said, this sort of thing isn't bad once in a while either. i guess you could say it's the reverse of the situations where one girl gets fucked once/twice by an entire parade of monsters/goons/whatever. XD
