I really wanna know what kind of crazy sex life she had with her former husband if he went "my huge tittied wife with an unbelievably sexy body wants to have so much sex with me that i have to leave her"
Title contains word: "Yahoo". My initial response (to quote Homer Simpson): "WOO-HOO!!!!!"
Disregard age difference or what others might think ... Naoki-kun Knows What Is Best In Life!
(Paraphrasing Yachiyo's dialogue): "He couldn't keep up with my sexual urges." ..... Ex-Husbando CLEARLY DID NOT have what it takes to be a Hentai Protagonist (sometimes, it's like that).
Yahoo indeed, training in Hentai is always a good thing. Helps you build stamina, for one.
Also, clearly her ex-husband wasn't a hentai protagonist. Kind of pathetic that he'd leave her because she wants too much sex, I can imagine many people would be happy to take his place...Like our protagonist here.
