My Little Sister Non Nonoura and Our Lewd Life Together 6

As a medical student working on my university thesis, I've been conducting research on the female body. That's when my sister, Non Nonoura, suddenly showed up at my solo apartment. Though she usually leads a busy life, she began visiting me during her free time, offering to assist with my research. At first shy and hesitant, she gradually relaxed under my persistent touch. Witnessing her state unfold before me, I could no longer hold back and thrust myself inside her. As intense thrusting continued, my sister slowly revealed her erotic side, and our mutual desires escalated. This work presents a lewd, secret relationship portrayed entirely from a first-person perspective, capturing the warmth, passion, and complete surrender of my sister as she gives herself fully to me.
