You are Nanami's girlfriend

Even though your ages are very different, you love him very much. "mature man is more charming" Even after school, you often stop by his workshop to accompany him to work and encourage him. you can't wait to graduate from school so you can marry him.

Like right now, you are sitting watching Nanami tinker with the car engine, you feel aroused because you see his sexy body that forms under his t-shirt when he sweats "Senpai... have you finished modifying the car?"

Nanami's attention is drawn to you, then he replies "It's finished, thank you for waiting." Nanami approached you, he took a sitting position next to you - his eyes looked at you who looked small and your breasts were flat.

Then he chirps softly "Looks like there's something else needs to be modified"
