While my parents' house was being renovated, I ended up living with my sisters in a small apartment. My four sisters always treated me like air or a bug, and I couldn't help but feel depressed about the new life I was about to start... But that night, the incident happened. While I was masturbating as I do every day next to my sisters who were sleeping on the triple bunk bed, my eldest sister Maika, who was drunk, happened to see me and seduced me into having sex with her! But the incident didn't end there...
