She posted on her free page that its a "podcast" with Rune coming out where they talk about "our recent sexual escapades". So a thing people wanted from Peach and she probably felt uncomfortable doing it alone so asked Rune to join her.
Knowing her it will basically be a podcast talking about strap-ons and maybe wearing one like a futa slutboy, then blah blah blah, but not talking while using one on another girl or herself.
