GDHH-068 Normally, my forceful stepsister and I are super close, creating a weird atmosphere! Suddenly, the stepsister who appeared out of nowhere has a cute face but a bit of a problematic personality? She's just so forceful and naggy, it seems like she

Suddenly, I got a stepsister who is cute but has an extremely assertive personality and hates me for being so weak! One night when my parents were away, a storm caused a power outage, leaving the entire house pitch black! Then, my stepsister came into my room with an unusually cute atmosphere and said, 'Can I stay with you until the power comes back on?' Being alone in the room with my frightened stepsister naturally led to a full erection! And it was immediately noticed! But, as my stepsister fidgeted while touching my erect penis, we ended up having sex right there!
