Wife here - you know, those egg vibrators are probably some of the best to use. I'll put one each in both my holes and then use the other like her. When the cock goes in (one hole or the other) then it enjoys the effects of vibration too.
I like how at the start she rubbed her legs belly and boobs in that pattern. For years I've done exactly the same and then every part of me becomes wired to the expectation of ultimate sexual pleasure - the brain sends out messages to "get ready." I've had times when I'm so sexed that touching my boob or belly can make me cum.
What an amazing sexual organ the entire body is!!!
