It's been seven years since I've been making my sister give me a blow job. We are now in a relationship that we can no longer separate.

What are we... it's been seven years since we've had this relationship with our older brother. It's a secret that only two people can never tell anyone, but... I can't believe the ending would end like this... In the midst of adolescence, the unsuppressed impulse towards sexuality becomes my younger sister Emma... a story about the sexuality of a brother and sister who have crossed a boundary that should not be opened up. Every day, I made my sister take a cock in her mouth...I couldn't resist just making her suck, and she crossed the line. My sister accepts it. My brother's sexual desire accelerates. Seven years of fleeting but sad brother and sister.
