HUNTA-455 — What!? Seriously? My Slutty Sex Friend Of My Slutty Senior Was My Sister! My Senior At My Part-Time Job Showed Me A Photo Of His Recent Sex Friend, And The Person In The Photo Was My Sister!? My Sister Grew Up In A School With Strict School Rules From Elementary School To High School, So She's Super Strict And Damn Serious. She Always Nags Me About How Sloppy I Am, And To Be Honest, It's Annoying...

The person in the picture of my sex friend that my senior at my part-time job showed me was my sister! My sister is always nagging me about how sloppy I am, but she was so happy to be fawned over by the opposite sex for the first time since entering university that she became a slut who would do it right away! I was shocked, but my senior asked me if we wanted to have a threesome! I had wanted to mess with my sister, so I decided to join in. On the day, my sister was surprised and tried to run away, but I caught her and we had a threesome together
