interesting idea for a story but not executed very well. The dialogue feels weird, and I didn't find enjoyment reading it. One character points out her mother will sleep with the MC and teases like she wants to sleep with you as well. Another talks to a friend and acts like she wants to sleep with the MC and then Immediately acts like the first sister is nuts. Then we are introduced to an aunt who also claims that the first sister is nuts after basically breaking into the house and threating you, while knowing that a son lived there. Then we come back to the second sister's friend showing up and you go back to her place. The MC's dialogue changes to not wanting to have sex with her.
This is a neat idea, but you need somebody to work on the writing cause none of it is consistent. At this Point I find it hard to actually want any of the characters cause they all seem nuts.
