My young step-sibling comes to me asking for help to kiss her and I then insert myself into her inundating her

My young step-sibling touched me today and asked me to teach her the right way of kissing. I took it up further, earnestly forcing myself into her, till I had exhausted her, in a good way. I suppose this sensual meeting of my mother-in-law’s daughter in law was satisfying to both of us.
