I'm looking for a story I read a while back.
It was an incest story, the protagonists being twins. It was a long story, I remember it being over 30 chapters. The twins mother and aunt was somewhat involved sexually with them, however, when their father found out (by finding a picture of them kissing left out in the open in their room) he freaks out, get mad, and the brother goes to live with his friends for a while (the friends being an other brother/sister couple). There was a girl from their school who was a real bitch, I think she tried to blackmail them at some point, but she became their friend when the protagonist was shot (stabbed?) at an ice cream café, saving the bitch's life.
Also for a while the two protagonists dated an other brother/sister (the ones that the guy protagonists went to live with when their father was pissed off) as a cover to their own relationship. And the aunt was living for a while with the protagonist's family because work was being done on her own house, I think.
That's about all I remember!
