Daughter’s slumber party, Part one

With Labor Day coming up, my 16 year old daughter, Rita, asked me if she could have her friends Courtney and Judi over for a long weekend “Goodbye to Summer” slumber party. Since I knew her friends, and was sympathetic to what the end of summer holidays meant from a teens point of view, I was happy to agree. Since my daughter has a queen sized bed, she assured me that at least 2 of them could sleep in the bed, if not all 3, then she would set up a sleeping bag, and if need be, they could take turns being the one to use the sleeping bag.
My daughter and her friends are teammates on the high school cheerleader squad. With the routines they do, they are all in excellent shape, athletic and toned, but not over muscled bodybuilder types. They may be well toned, but they are still very much 16 year old teen females. Rita and Courtney have been friends since they were 6, and with their blonde hair, blue eyes, and fair features, they have been mistaken for sisters.
Judi has been friends with them since they were 10, and she is a cute redhead with a light spray of freckles across her face, neck and shoulders. Courtney and Rita are both 5’7″ tall, Courtney weighs 115, and Rita is 120 pounds. Judi is an inch shorter, at 5’6″ and weighs 110 pounds.
Late Friday afternoon, the girls arrived, and they were very excited to be having a 3 night slumber party. Feeling a bit festive myself, I ordered pizzas and we had pizza for dinner and ice cream for dessert.
At 10 PM, I felt myself drifting, it had been a long, tiring day at work, and I said goodnight to the girls, and headed off to bed. I was asleep withing 5 minutes of my head touching my pillow.
I came awake, it was 1 AM. I was very thirsty, and went off to the bathroom for a glass of water. My bedroom was down at the far end of the upstairs hall, and the bathroom was right next to my daughter’s bedroom.
I noticed the door to my daughter’s bedroom was slightly ajar, and I heard low murmuring voices in her room.
I suddenly heard my daughter’s voice, in a low sexy growl, say, “Have you been a bad girl?”
I heard a giggle, then Courtney’s voice whisper, “Yes, I’ve been very bad!”
My daughter whispered back, “In that case, you know what needs to be done, assume the position!”
I heard the creaking of bed springs, a pause, then I heard a whap, followed by a moan, whether of pain or pleasure, it was hard to tell.
