SSIS-998: Got My Cheeky Stepsister to Be My Sex Practice Partner on the Promise She'd Never Let Me Penetrate… 日向陽葵

About this work

My stepsister '陽葵' came from my father's remarriage. At first she seemed cheeky and I thought we'd never get along, but an incident brought us closer. When she found out I had a girlfriend she unexpectedly said, "You — an introvert — actually have a girlfriend? You probably have no experience. If you promise not to let me penetrate, I'll be your sex practice partner." From there it escalated from just rubbing our genitals together, to 1 cm insertion, to only the tip, and eventually she used her incredible body as practice for real sex, and we drowned in the pleasure of it.
