マゾカノ ～寝取られ志願～

Your childhood friend feels good when violated by men other than her crush,
and so do you when she's violated. A CG collection with Voice and Story.

While being on a train to the school, your girlfriend gets molested in front of you.
You come to get, instead of stopping the molester, a sexual inclination of that kind.

And, it's not only you to get that immoral kink at that moment......
