HMN-709 I was only teaching him how to use a condom! But when my plain older sister made her college debut… her overflowing desire exploded!! She becomes an affectionate older sister, riding him in a grinding position and begging for climax. Tojo Natsu

My shy, introverted older sister had a total college makeover… and even got her first boyfriend, so she’s been really excited. But since she had no romantic experience at all until now, she seems worried about her first intimate experience… and she asked me, her younger brother, to teach her how to use a condom. She said I was the only one she could ask, so please… Even so, what was I supposed to do? I ended up showing her how to use one, and things took an unexpected turn. My sister, who had awakened to her desires, then started asking out of curiosity to learn what it feels like without protection…
