I tutored my cousin, who had poor grades at school but was incredibly skilled at sex and could achieve great orgasms, and was repeatedly drained of my semen 12 times. (Amagi Hanami, STARS-564)

My cousin, whom I've played with since childhood, came to visit. I don't know when she turned into a terrible student; she's terribly bad at studying. I had to endure her pranks, fueled by her strong libido, to tutor her. My well-developed and experienced cousin looked so happy after I ejaculated… A video of 12 consecutive ejaculations, completely dominated by her!
