I just opened the door and exclaimed loudly, "BECKY!" As I saw her sitting on the floor, her back leaning up against the bathtub, and her legs were sp...ead wide as she fingered herself rapidly.Shocked to see me, she stopped shoving her finger into her pussy and said, "Well, you sure can't get me off!"Furious, I looked at her and said, "Like hell I can't," and immediately dropped to the floor and crawled between her wide legs until my mouth covered her dripping smooth slit."Oh!"

I quickly showed them how to approach the horses and make contact with them to assure the horses.
