[MIAB-358] Erotic Manga Research Club: I, the homeroom teacher, was studied so lewdly by a plain, glasses-wearing, big-breasted member of the club as a model for drawing materials that my cum flowed back out. Shion Yumi (Censored)

[Serious = Super Erotic] A plain, glasses-wearing, busty J-cup student's eroticism awakens. In order to draw erotic manga, she studies men in a "practical" session with her teacher! She transforms into a lewd, slutty student who licks balls, nipples, and even armpits! She wraps his dick whole and gives him a titjob, making him cum! Her huge breasts shake as she pounds him inside! She shows off her voluptuous body in a spider cowgirl position! She shoots thick semen in a kiss-hold missionary position! She continues her erotic research by ejaculating to make the work even more erotic! As a teacher, I have to stop her, but she can't resist the pleasure of her soft, fleshy body, both inside and out! She's already cumming... Ah! I'm cumming again! Her sexual desire runs wild due to her inquisitive spirit and youth!
