Manga title help

[DontMakeMeDoItMason]

I'm looking for an ecchi manga. It's about two childhood friends who can see the other whenever they masturbate. Both parties don't know they're being spied on whenever they do it. If I remember correctly, they made a promise to a witch, which may be the cause for this weird premise.

I just randomly remembered this series in the middle of the day. I think it was finished last year.

Thank you
