The one we use is a tube of glass with a soft rubber end that fits over her cunt Then there’s a squeeze valve on the other end that I can use to make a vacuum. It’s nice because I can watch her pussy lips get sucked into the tub we usually keep it on her for about 10 to 20 minutes to really pump it up extra large Then it’s just a matter of sticking my tongue in her when she’s done she gets totally off on it. Which model did you guys get? Does your wife like to get stuffed with big toys too? They go hand-in-hand pump that cunt up and shove a big dildo up inside of her. She’ll love it. Believe me you’ll love it too then slide your cock inside of her. It’s an amazing feeling.
