I never saw Bible Black nor Discipline due to the dark content. After reading Cleavage's premise and actually watching it, I realized that this was the lightest h-anime that this studio ever made.
I love the English voice acting and the sex scenes were done well. Ileana Castro has a sexier moan than Mitzi Shanks even though I also like hers as well. My favorite sex scenes were the computer lab lunchtime one, Yuuto and Erika's first time at the music room, Yuuto and Sayaka's first time at the art room, & the big three way at the end. I'm happy to see Erika and Sayaka kiss during the three way. I like the implication that Yuuto is in a three way relationship with Erika and Sayaka with the girls having their own scheduled days with Yuuto. It was nice that Yuuto managed to convince Morikawa that Erika's not into her when she attempted to rape her and she decided to protect Erika's happiness. She even went so far to protect her from Kuno sneaking some pictures during PE.
The design is similar to Bible Black and Discipline. I like the design of Erika, Sayaka, and Morikawa's panties. I'm surprised almost every female student doesn't wear a bra. Erika's casual attire is too revealing but I'm not complaining. I love how Yuuto managed to solve the problem by saying "If you're going to do this, then we should all fuck" which was the most sensible yet hilarious suggestion ever even Erika and Sayaka's replied in unison "We should all fuck?".
