Nico Joku [English], an hentai doujinshi parodying the Love Live! series, by Kyockcho
Best leave morality questions alone here. It’s about the petite Love Live idol Yazawa, blackmailed into having sex (to protect her school etcetera), loving it against her will, and so on.
Simply, the drawings are excellent (strongly reminding us of the hentai god Hisasi), and if you either have a “force her to bend and come against her consent” fetish or care for highly polished quality hentai art, it’s something you should like. It’s up to you =)
This has been released by BThreeTwenty, thank you!
By the same artist, to this day, I also share Nishizumi Shimai Ryoujoku 1, Nishizumi Shimai Ryoujoku 2, GirlPan Omakebon Matome, Namaiki Karin, and Maiden Breed.
