Brunch and Orgasms - erotic short story

Rina works in the porno industry, so she ought to be the perfect person to ask when you want to know something about orgasms. And yet, she doesn't have a clear answer when her friend asks her what he ought to do to give his sexual partners multiple orgasms. But then Rina has an idea. She invites three women to brunch, whom she only met online, to discuss it with them. They have been writing about sex for a long time and have a very relaxed approach to the subject.
It turns out to be a naughty and hedonistic day, where the brunch buffet contains not only fruit and croissants but also a tray filled with dildos and other sex toys.
