“Hmm,” said Mrs Prentice. She put her finger to the hole and pressed gently. Involuntarily Jennifer tightened her ass again. Mrs Prentice pressed a little harder. “Push down,” she said. Jennifer did the best she could. Mrs Prentice pressed against her anus again. This time the finger went in, nearly up to the knuckle. It felt different from having Miss Flora f**k her with a strap-on. The finger was alive, it moved. It was more intrusive, even if it only went in part-way. Mrs Prentice took her finger away. She fetched some lube and applied it both to her finger and to Jennifer’s ass. Then the fingering resumed, but this time much harder. Mrs Prentice rammed first one finger, then two into Jennifer’s ass over and over again. At last the fingers were withdrawn. Now it was time for the plug.
