I turn around and slide my tongue in between her full lips. I feel her hands start grabbing on my buttocks, pulling me even closer to her. Catherine doesn't know that I was already about to cum when she entered the showers. Her hands are squeezing my ass, tugging on it so hard it almost hurts me. My buns are so wide apart I can feel my anus and pussy open. I bet they are squelching with juice - but we can't hear it, thanks to the sound of running water. My hands are rubbing our breasts. It is such a pleasure to hold two sets of tits squeezed tight together instead of massaging just two boobs! I keep trying to bring our nipples together and when they brush against each other, we just come melting from pleasure. Catherine finally gives in and lets out a loud moan.
