The Lion Man and the Geek Girl -My First Time Was with an Animal-
Koi Wasure Onna no Ko ni Hatsujouki ga Kuru Sekai de
Interesting concept, but doesn't follow through with its original idea. Genetic engineering that makes the females unabashed by seeking out reproductive activities from any males, yet not one classmate is pregnant. Rape/sexual assault charges have no merit. Can have sex with any male/women in the world and pop out children without consequences. The theme is just unrequited love with childhood friend, include sex, nothing special.
Ai x Yajuu
Your typical smutty shojo manga with transforming werewolves and feebly female priestess lead. VERY cute animals. Smut in all areas of the house/neighborhood. Ending/after story with the daughter and her "birth guardian" complicates my feelings for the story.
Koakuma na Osanajimi ni, Itadakaremashita Beddo no Ue de
Childhood male friend takes advantage of female's generosity by utilizing her as a "homemaker mom" all the way to adulthood. Decides to force himself on her when she pulls away from him after having enough of his disrespect. She continue her homemaker status with him after sex.
Love in the Fujinami Household -A New Romance Begins in the Family!?-
Aku no Joou no Kiseki
Mary-Sue type girl transported into magic world and became the tyrant queen in the battlefield. Every male that hated her previous queen-version now loves her docile form, will do anything to/for her, and she lets them treat her as a (invalid) pushover toy. Male characters are pretty, but not enough to keep reading about her.
