Shannon broke off from me and went to her. "Hi Sam, great to see you!"
They hugged and Sam kissed her on the lips. Shannon responded to her with more enthusiasm than I expected, and held Sam's embrace long enough to arouse me as one of Sam's hands wrapped around Shannon's shoulders while the other rubbed Shannon's ass. I got lightheaded as I thought about the possibilities of tonight. I was staring at my sister when she said "what?"
"You and she..." I said.
"Yes," she said. "I knew Shannon way before you."
They both smiled at me. "It's true," Shannon said. "We were fooling around in high school."
My sister's hand was still on Shannon's ass.
Sam had been preparing a nice dinner and after Shannon came into the house and rested up, we all enjoyed a nice meal and sat out on the back porch with a few bottles of wine catching up. Shannon yawned and asked if it was all right to cut the evening early. We all agreed and went back into the house.
I followed her into the bedroom where she started to slide out of her dress before I could close the door. Sam was watching from the hallway. She hung up her dress and unfastened her black bra, dropping it on the bedroom chair. Her lacy, frilly yellow panties showed off her behind as she shimmied out of them to be nude. Sam was in the doorway now and we were both mesmerized. Her compact body was a work of art. After the tantalizing view of her ass, she turned around and smiled at us. Her round, full breasts, jutting out and the demure triangle between her legs were intoxicating.
Sam had had enough of the show, and backed out of the room closing the door and said "you kids have fun." Shannon smiled at me and gave me a come hither gesture with her finger. I was out of my clothes fast. She pulled back the bed sheets and I came up behind her, pressing my erection against her gorgeous ass. I reached around, cupping her breasts as I kissed her neck and nibbled an ear lobe. She sat down on the bed as I stood in front of her and took me in her mouth. I almost lost it. She pulled my cock forward to delay me cumming as her mouth and tongue worked on me as she locked eyes with me. She stopped before I finished and scooted back on the bed, her head resting on a pillow as her legs opened up to me.
I climbed up on the bed after her, positioning myself between her legs, kissing her and fondling her ass. I moved down to her breasts, squeezing one and taking the nipple in my mouth, swirling my tongue around it, while my other hand grabbed her other breast and pinched her nipple, like I knew she liked. I took my time, switching my mouth to her other breast so it wouldn't be ignored. The contented sounds she made fueled my energy. My hand roamed to the moistness between her legs. I began to trace a path from her chest down to the heaven between her legs with kisses. I reached that wonderful place and took my time caressing the inside of her thighs with my lips. I placed my hand to where I could pull back the hood of her clit and gently took her in my mouth, wanting to get her ready.
She started to squirm and moan, but I grabbed her hips so she could not get away, and started sucking on her clit. Her frenzy escalated until she screamed at me "I need you in me now!" I waited and kept doing what I was doing. I wanted her to get to the point to where just before she would beg. That always made her mad, but I didn't care. When I couldn't take it any more, I moved up between her legs and entered her. Her very tight pussy receive my fat cock easily, but she still gasped I shock. I began thrusting and banging into her and her cries got louder. I didn't care what Sam would be hearing. I kept pumping as hard as I could until she said "Now!, do it now! fill me with your hot cum!" It was too much. As I emptied into her, she wrapped her legs around me to where I could penetrate her deeper. I kissed her long as we finished. It boggled my mind as I wondered what the rest of the week would be like.
