[Reducing Mosaic]SSIS-998 I made a promise to my bratty sister that I would never penetrate her, and then asked her to be my sex practice partner... Hinawa Yotsuki

My step-sister 'Yo Aoi' was born to my father's remarriage. Her first impression was that she was cheeky, and she thought that she was the worst and that they would never get along, but after something happened, their relationship became closer. When my girlfriend's younger sister found out that I had a girlfriend, she said, ``You're a secret guy, yet you managed to get a girlfriend?I don't have any experience anyway, so if you promise not to penetrate me, I'll let you practice sex with me.'' ” and an unexpected invitation. From there, she just rubs her genitals together, inserts just 1cm, then just the tip, and it gets really real, and finally she uses her amazing body as a practice platform for real sex, drowning in the pleasure of sex!
