You know, about a million people a year will read this blog at the current readership rates… you never know, she might be thinking the same thing…
You could, could just ask… ‘Umm, so would you mind if I masturbated sometimes. Don’t worry, I won’t be cumming?’
Then again, you could just go for it. People are wonderfully reserved. You could probably fuck yourself senseless and she’d just pretend it wasn’t happening.
