Kanashii Doubutsu
I really didn't like this one. Filled with rape and altogether unlikable plot. Also not fan of this stocky art style.
Otoshiana ni Hamerarete
Though not a fan of rape trope , man were these two bishi's compatible. I actually like the seme, unfortunate what happened to him in the past which affected his actions though. Hot stuff though.
Only You (MOEGI Yuu)
Didn't care for it much, but the sexy scenes are good, if you ignore the story.
Hitorijime Boyfriend
Forced feelings don't equal love but a crime.
Sono Futari, Enjouchuu Ni Tsuki
Completely ignore the plot and there some decent smut. But the stories are just romanticized rape, except the third one which is a concensual threesome. Also the the seme is being the one forced in the first one which I have never seen before.
