Aunt Ruby was talking about her time in Paris, heavily 'edited' for her folks' hearing, and I got bored and went up to my room and got on the computer. An hour or so later I heard Ruby talking to Anita then it got quiet.
Then Ruby came to my door and motioned me to come to her. In a shot, I was there and she put her fingers to her lips and then kissed me soundly, her talented tongue fencing with mine, her hips sliding against mine.
She pulled back and whispered in my ear. "When it becomes ten o'clock take this glass and wet the open end and put it against the wall of my room. Your ear to the bottom. I think you will enjoy our talk." She gave me a long stimulating kiss and fondled my cock through my pants. As she turned to leave, she whispered "Sorry for the dinner interruption. I was going to give the twins a real eyeful and you!!!" Then she was gone.
I knew the 'glass listening trick' but had a better solution for listening through walls, a medical stethoscope, one of the newer digital ones, that gives much better listening. I bought it used from a med school dropout. The walls between rooms, in this house, have no insulation between them, and sound travels easily between rooms.
I closed my door a little before ten and put a towel against the bottom so no light would show. I was 'asleep' for all practical purposes. I taped the steth to the wall and put the earplugs in my ears when I heard voices in Ruby's room. It was Mom and Ruby talking normally, for the room was isolated, or so Mom thought.
"Was Paris and France as decadent as always?" Mom asked. "Tell me all the nasty nice things you did while you were there. How many lady loves did you have, any that I met while I visited you?
"I went to the Sorbonne for three years and got my Masters in Art History and there were many like-minded girls and ladies who I got to know very intimately. Oh, Jeanne DeVonne said to tell you that she still remembers the three of us making love almost all night. She said give you a very intimate kiss on your pussy for her. I told her I would do just that. Now let's get nasty nude and make passionate love as we have done for years. We have all night.
"You are still beautiful after all these years. I had a boob job when I started to sag a little. They did a splendid job, with no visible scars and I still get raves from lovers. Like them? Suck them while I put my hand on your dripping pussy and finger you. Wait till I try a new trick on you I learned from a lady from India. Her mother taught it to her when she was young. No taboos there on that.
"I wonder if the twins are making love across the hall? They are both gorgeous and so damn sexy. I got them to take off their bikini tops at the pool while we swam. and they have beautiful breasts. I'd love to watch them making love. You ever watch them, come on, truth, Sis?
"Yes, but it was an accident both times. I had gone out and had told them I'd be out for two or three hours. But came back early, they were in their bedroom making love and I went upstairs and heard them moaning and knew they were making love. The hallway was dark, it was evening, and I stood in the dark and watched them in a 69. I got so horny watching them eat each other I brought myself off twice as they were eating each other for a long time. They must have had four or five orgasms, each. They and I were really horny. Lots of fun to watch too, my daughters eating each other.
"The next time was different, I accidentally walked in on them in the den while they were watching a porn video and the sound was up and they didn't hear me come home. Amy was on her knees and Anita was behind her with my strap-on dildo that I use sometimes on lady friends. It's a least six inches and nice and thick. Anita had it deep inside Amy and was moving her butt from side to side.
You'd have been proud of her technique, I was! Amy really got royally fucked, deep and hard too. Her lovely breasts bobbed and jumped as Anita fucked her. Amy screamed when she climaxed and I backed out and disappeared. They never knew Mom was watching. Ohh, yes Love, just like that! A little deeper! We have all night. Now let me eat your delicious pussy. I need to eat you, Lover! Your pussy always smells so damn sexy and so delicious too."
I listened and jerked off wishing I had one of the new digital two-inch cameras you can hide almost anywhere and are motion sensitive. They have the infrared capability for low light use. Amazon, here I come in the morning. The two were still going strong when I went to sleep at three AM!
I slept in and missed breakfast but I wasn't hungry. I looked out one of the windows that overlooked the pool and there in all her naked glory lay Ruby sunbathing. I brushed my teeth, combed my hair, put on my skimpy bathing suit, and went down. I pulled up a lounge near her, and turned so I could take in all her beauty. She looked a little tired and I wondered how long she and Mom had made love last night.
