Paula smiled and agreed to take charge of Marlene. Standing up straight: "Marlene, come over here and suck on my pussy, if you please."

Marlene gave a start at the suddenness of the demand, but dutifully kneeled down in front of Paula and buried her mouth in Paula's pussy.

Paula remarked, "Wow, Sis! That was fast. I thought we were going to have to spank you or something." Paula spread her legs wider to allow Marlene greater access.

"Of course," I answered.

Marlene held her cheek and looked at Paula fearfully
