Chikan Shita Joshikousei to Sonogo, Musabori Au you na Doero Junai
Our protagonist is a run-of-the-mill businessman in his late 20s with no girlfriend. There is a cute HS girl he sees on the train every day. She's well developed, with nice hips, and a healthy figure. If only he could marry a woman like her...
One day our protagonist molested her on the train. When she didn't struggle, he brought her to a hotel for sex. This would be the first time she has had normal sex. That's when she learned how good sex can be, and he learned about her tight ass and voluptuous tits, her family-oriented and nice personality, and how she's a dirty girl.
PD: the 3D animation is good enough imo.
