This Love Is Forbidden

The story is about Amy and Kevin. They love each other a lot and are siblings, but of course not biologically. So what will happen in their love story? Let's read it.
***
The story is about Amy, who falls in love with her adopted brother Kevin, but it's not clear to her if he's really adopted or not. It's only her who thinks that he can be, but she isn't sure.
Everything was fine in her life until one day she entered her brother Kevin's room and heard him jerking off in the bathroom. As she was going to leave the room, Kevin called her, and she turned around only to see him all wet with water. He was looking hot with water dripping from his body, and seeing him like that was making Amy feel hot too.
Kevin also didn't want to let her go. He always dreamed about her being under him and as today he finally got the chance, he wasn't going to let it go.
Will Amy let him do whatever he wants to do, or will she reject him?
And will Kevin be able to tell her who is the adopted child and what the truth is the whole family is hiding from her?
