Kana-chan, a junior at the same company, is a plain girl with glasses, and when you talk to her, she's surprisingly cheerful and frank. I unexpectedly went on a date with Kana-chan, and I was Kokoro by her unexpected enthusiasm and cute smile. A few days after the date, Kana-chan came to my house and we got together, but when I took off her clothes, I was surprised! She had unexpectedly big breasts, and her sex was erotic, and she had a perverted temperament that accepted all my desires, making vulgar voices! "I'm cumming, senpai!" she screamed loudly as she shook her big breasts on top of me and came over and over again!
