My stepsister, who is the same age as me and came from my parents' remarriage, was born a month earlier than me and often rides on top of me. She makes me ejaculate every day. (Miya Nanazawa, MIDE-823)

After my father remarried, he had a new stepmother and her daughter. She was like a petite and adorable little sister, about my age? After asking her zodiac sign, I found out she was actually born before me! She turned out to be a super S-type older sister who often rode me in a cowgirl position!
