Monday morning came and I dressed and went in to work. When I came home that afternoon, I changed and settled down with a cold beer. Then the door bell rang. When I answered it, it was Alison with another girl who looked a lot like her. I motioned for them to enter. When I closed the door, Alison unbuttoned her blouse, unzipped her skirt and dropped both on the floor. She slide her feet out of her clogs and stepped to one side to get away from her skirt. She assumed the position, over the arm of my love seat with her butt in the air and her legs spread. She put her hands on her butt cheeks and spread those cheeks showing her asshole. Then she said, "Fuck my ass, please."
"Hold it a moment!" I said, "Who is with you and why?"
"She's my sister, Amanda. She wants to watch me get fucked. I want it now!"
I was wearing a pair of shorts and a tee-shirt, I pushed the shorts down and moved in behind her. I pushed my cock into her asshole until my balls were resting on her cunt.
"Ooh! Give me that cock! Pump my ass! Bang me! Oh! Uh!" She continued to talk dirty while I pumped hard and deep into her ass. I didn't hold back and quickly pumped white cum deep in her ass. When I stopped, she pulled herself forward off my cock, turned around, knelt down and swallowed me down her throat sucking all the cum and ass juice until I was clean. Her sister just watched in amazement as all this happened without saying a word but breathing fast and hard.
I looked at her and said, "Well, Amanda, do you like watching your sister get butt fucked?"
She nodded her head slowly and replied, "Oh, yes. It's so hot. I just didn't believe Alison was into hot sex like that even though she said she was."
Alison said, "She has always been more active than me, but now I can show her a few things now."
I said to Amanda, "Strip off. Let's see what you look like."
Amanda looked doubtful for a moment and Alison said, "You said you would if I proved I could get it up my ass. Now, Sis. Do what you agreed." With that, Amanda started by pulling her blouse over her head, kicked off her shoes, and unsnapped and unzipped her jeans and peeled them down her legs. She stood there in bra and bikini panties until Alison said, "Take it all off. You said you would." Amanda reddened a little but reached back and unhooked her bra. She slipped it down her arms and off. Then she put her thumbs in her panties and slid them down her legs and stepped out of them. Now, she also was totally naked. Like her sister, she was a bit taller than average probably around five foot, nine or so. She had more tits than Alison by just a little. Her waist was small with a flat stomach and nice hips. From the front, it looked like she would also have a nice, tight ass. I motioned for her to turn around and she slowly rotated letting both her sister and me have a good, thorough look at her body.
I liked what I saw and my cock started to harden again. She saw my reaction and smiled.
"Is it my turn now?" she asked.
I nodded, "Where do you want it?"
"Fuck my ass, too. I like it hard and deep."
She turned and bent over the sofa arm and I chuckled, "Sisters are alike."
