SSIS-998: When I asked my sassy stepsister to be my sex practice partner on the promise she'd absolutely never let me insert… 日向陽葵

About this work

My stepsister 'Hinata', from my father's remarriage. My first impression was that she was cocky and terrible, and I thought we'd never get along, but something happened that brought us closer. When she found out I had a girlfriend she said, “You, a shy introvert, got a girlfriend? You probably have no experience. If you can promise you won't insert, I'll be your sex practice partner,” an unexpected offer. From there it escalated: just rubbing genitals, 1 cm insertion, tip-only insertion, gradually moving into real sex, and finally she used her incredible body as practice for full sex, and I drowned in the pleasure!
