The content page of Vol. 3 has art of Rion groping Erika’s breasts.
The extra chapter (Pg. 221 That’s our secret.), is about Erika back in school masturbating to other girls and then discovering another girl masturbating as well.
The book jacket is an altered version of the Vol. 3 Cover with Rion and Erika looking more erotic.
I had to take these pictures with my phone because Vol. 3 only has a physical release, there’s no digital release to buy. And I don’t own a scanner either, so I’m sorry about the quality.
Emily tells the MC: “I won’t let you have sex with Chika until you say you love her.”
When Emily realizes that it’s not enough motivation for him, she starts to have lesbian sex with Chika while pretending to NTR the MC as a way to provoke him.
Chika immediately realizes what Emily is trying to do, so she plays along with the NTR teasing, which eventually results in the MC stepping in.
Manatsu catches Ikuta cheating on her with Kanon, but instead of getting mad, she quickly hides and masturbates to them. After they finish, Kanon finds Manatsu and they both go home with the MC.
Kanon decides to tease/seduce Manatsu about getting turned on from watching her boyfriend having sex with someone else and wants to “teach her” how to please him. She uses a sex toy on Manatsu while Ikuta watches and has sex with her in ways that will please Ikuta if used on him.
