Wife Masturbating

I absolutely love it whenever my wife masturbates. But one of my favorites is when I am asleep and l wake up to the sound of her moaning and the buzzing of her wand. Usually this happens after a particularly good long sex session. When she knows I am awake again, she tells me “ I think I have a few more left in me” she has been known to have waves of orgasms that sometimes lasted 30 or more minutes. Sometimes she will take care of everything and I just hold her. But most of the time as she starts to get close she asks for me to suck on her nipples and finger her butt. Either way is good for me but having a finger in her ass as she climax’s is my favorite. I just can’t get enough of her orgasms.
