Your NTR girlfriend is cuckolding you with your stepsister...
I'm enjoying it but the characters keep getting mixed up. One says their my girlfriend then the other is. Then all of a sudden they are both sisters. But other then fixing those issues as I go, It's pretty good.
I kinda snapped a bit,I felt betrayed like a MF walking in on that.that type of shit while kinky,makes you have trust issues with chicks
