Prova nel diario di an otaku delle ragazze abbronzate che lui ha allenato sessualmente vol.2 - parte 3

A geeky, neat, no-good guy gets a gal who's on God's waiting list for an all you can eat buffet. She's looking for a place to sleep. He was looked down on, called creepy and weird, but he is able to bring her to her sexual peak. Even we respect him for it. She feels even weirdo's cock, and as she gradually becomes more and more obedient, we see the pathetic nature of women!
