This gal wants to repay me, an erotic manga artist, with her body! [18+]

"How about touching my body... and using it as material for your experience?"
Akira, an erotic manga artist, gets a rejection on his manga before the deadline, loses his wallet... and is a virgin! Akira, an erotic manga artist, has been having a lot of bad luck.
Then, Akira's room is visited by... a gal he rescued at the train station a few hours ago!
The loyal gal, Kanon, wants to do something to repay him, but when Akira sees the manuscripts scattered around the room, he is immediately exposed as an erotic manga artist and a virgin, and she makes him a proposal...?
"I'll do my best for you, teacher..." When a cute gal says that to him in front of my soft, warm breasts that he's touching for the first time in my life... he can't stop himself!
