My constant attention to her lips and clitoris was having the desired effect – I could feel her hips rise and fall and the pressure of her hands on ...y head gave me all the directions I needed. Once she was convinced that I knew what she liked her hands disappeared from my head. I glanced up and she was looking very flushed and her hands were kneading her breasts like a master baker – she was pinching her nipples quite hard and they reminded me of cherries. Her eyes were closed and she looked. Can't be Dad and the house was all locked up. Just then sis turns the corner, sees me naked just starting to dry myself off. She found Dad asleep and came looking for me. She apologizes and starts to leave. I say "Nothing you haven't seen before". Then to my surprise, sis turned around and we started chatting. Sis came to see Dad as it had been a few months since the last visit and she was feeling guilty that only I was caring for Dad .She came right from work and was dressed wonderfully.. “My…my name is Susan.” “Christine, Hi, oh and relax I won’t hurt you.” She extended her right hand and took hold of Susan’s left hand. Her grip was gentle, reassuring and her skin was so soft and smooth. Her fingernails were freshly manicured and painted a dark red. The music playing was a collection of Top 40 and some club remixes. The volume varied and Christine moved in closer so as to be able to talk with Susan. Her left hand was positioned on her stomach and her fingers pointed down to. ..and Ken and I took off our shirts ....So we all did and you feel the sudden increase in sexual tension as each of us showed off. Ken seemed to have a rise in his pants and we all noticed it. He had told me he had a 8 inch cock and had had lots of women...mine was more like 6 in....but I knew Ellen would like to see a larger cock.We chattered about how great the girls looked in their new suits...and next went into the spa.....we eased down into the water with only our heads out....and then.
