I got to say, I never expected Mahiro to have this kind of manga in his collection. Granted, we don't know a lot about how he was before he turned into a girl.
Well, seriously, (s)he should expect to have some misgivings about someone being forced into behaving in some demeaning way someone else wants them just because they're physically a girl to start with...
You mean, the exact situation he's been in since the start of this series?
What am I thinking...I was dangerously close to becoming my little sister's little sister there...But... I felt really safe yesterday, huh...Surprisingly enough, Mihari isn't that far behind Kaede-chan......Hah!I can't let this happen! Read this erotic manga and remember your old self...!An enslavement and training oneHIIEE!!A strange trauma was left behind.ContinuedSlave Girlbam!
