not as popular as milfs but there is audience for grannies too.
If the first sex scene in your "visual novel/erotic game" "spiritual sequel of a porn game famous for the corruption of Hermione" is with a granny ,not as popular as milfs and not with one of the four main girl to corrupt, like....is a bit weird as an opener.
"Hello there here is a visual novel in hogwarts where the first girl that you have something with is McGonagall, yup, and we are gonna do a lot of changes to that scene. Hermione? handjob and lesbian kissing with you, not with Ginny or other girl? fucking Hermione? nope! not at all!
To be honest, is a bit weird, nice of you to use more thing of the wizarding word for the plot, but the plot.....
and fucking McGonagall as the first sex scene.....why?
such art, such posibilities....
