I like Maplestar as much as the next guy if not more but, the guys above are correct. Beside the lack of penetration, I don't know why Maplestar can create tons of diverse frames for non-sex parts, very interesting and cool, but man look at that boobjob scene when Itadori's sitting on Nobara. It's LITERALLY made of just two animation loops switching between each others. What in the hell man...
One can only wish he re-allocates his time and effort on all those non-sex scenes to fully commit into making longer sex scenes with more diverse frames.
The artstyle is obviously goated as always no doubt about that.
