My wife uses our new Shark vacuum cleaner to suck on her Clit and Labia as she gets off from the vibration of her flapping back and forth inside the tube. Be careful because a lube is needed as it sucks so hard and tight. Coconut oil is what she uses. It is so addicting because she cums over and over and over again time after time and when I pop in she squirts like a faucet. Since then she made a fitting for the vacuum to suck me too and now I know why she was crying and cumming so loud.
