It was a typical Thanksgiving dinner, with an oven-stuffer turkey and all the trimmings. Mom outdid herself, as usual, with her famous corn chowder to start with, the traditional potatoes, sweet potatoes, and numerous platters of veggies and homemade bread. When, at last, no one could eat another bite, we all helped clean off the table and looked forward to dessert a couple of hours later.
Uncle Joe, dad and grandpa poured themselves some Cognac, retired to the den and turned on one of the football games. Mom, Aunt Joan and grandma sipped Creme De Cocoa or Sambucca while sitting in the enclosed porch, chatting and watching the birds in the backyard feeder. Chrissy and I followed some of the game with the men until, one by one, we all nodded off for a little nap. So far, it had been a typical Thanksgiving dinner at our house.
I awoke to the sound of a marching band during the halftime show and, as my eyes began to focus clearly again, saw Chrissy sitting across from me and watching the TV. Everyone else was still sleeping; Chrissy must have woken up first and sat with her feet up on the sofa cushion, legs bent at the knees. She was wearing a long dress, typically what the ladies wore for holidays at our house. Slouching down a bit, with her knees up in the air, the dress stretched across her legs and formed a wide opening through which I could see her bottom and fancy white lace panties. The pose reminded me of something an innocent young child would do.
Chrissy soon noticed me looking under her dress; when our eyes met again, she wet her lips with her tongue, puckered up and blew me a kiss. She then reached around her raised legs and pulled her panties aside with her left hand while rubbing her pussy with the other. Clearly, Chrissy was not a little girl anymore.
I quickly frowned at her and pointed at dad, grandpa and Uncle Joe, reminding her that they could wake up at any second. For that matter, one of the other women could also walk into the room. Chrissy didn't care and continued to play with herself, holding her pussy lips wide open as she dipped two fingers into her honey pot. I was getting a hard-on watching her and began to rub myself through my pants. This was crazy and I was nervous that she was going to get caught.
Suddenly, dad stirred in his chair before waking, then looked over at me as I quickly moved my hand away from my crotch. He rubbed the sleep away from his eyes and asked, "Hey, Danny, what's the score?"
"I don't know, dad," I replied, "I was napping too and it's half time now." As I spoke, Chrissy put her legs back down on the floor and smoothed her dress over them, looking perfectly innocent again.
After several more minutes, everyone else had woken up but we still had some time before anyone would be ready for dessert. Chrissy got up and walked over to me, asking, "Hey Danny, want to play a video game?"
Our basement was a finished room with sofas and chairs and another TV; we had lots of interactive games and I thought Chrissy had a great idea. "Sure, let's go," I said.
The second half kickoff got underway as we left the others; I opened the door to the basement before we bounded down the same stairs we'd been using to get to the playroom since we were little kids. Chrissy turned the TV on and I began looking through the game titles for something we would both enjoy. By the time I turned to face Chrissy and ask what her preference was, I came face to face with my sister leaning against the top edge of the back of the basement sofa, dress hiked up again, and her fingers rubbing her pussy once more.
"You better be careful someone doesn't come down to join us and catch you playing with yourself," I warned her.
"Don't worry so much, bro," she replied, "if I hear that door at the top of the stairs opening, I've got plenty of time to get my act together."
I just looked at her and shook my head in disbelief. I was coming to suspect that, in the past few years at college, my older sister had acquired a whole new attitude toward sex! "I can't believe how horny you've been lately; what's gotten into you anyway?"
Chrissy stopped fingering herself, hopped off the sofa back, and let the hem of her dress fall again. She walked over to where I was standing, looked me straight in the eyes and replied, "YOU, Danny... you've gotten into me, and I like the way it's made me feel. None of the guys at school have excited me the way that you do."
I studied my sister's beautiful face as we gazed at each other and realized, for the first time, that we had indeed found a special relationship with each other. I was still worried that she lied to me about being on the pill and that I was going to get her pregnant. But, everytime I brought the subject up, she assured me everything was okay. I guess I was just going to have to trust her.
She placed her arms around my neck and pulled me close, planting a long, wet kiss on my lips. I reached around her slim body to hold her tightly and opened my mouth to feel her tongue reaching out for my own. Her large breasts were sandwiched between our embracing bodies and I let my right hand slip down to her ass, squeezing the firm cheeks and feeling the deep, shapely curves of her butt. Moving my hand lower, I dipped under the hem of the dress, raised it up enough to get my hand down the back of her panties and massaged the soft, smooth skin. My hard-on quickly began growing and I started to grind my pelvis into my sister's.
Chrissy released her hold on me and slowly pushed herself away; I removed my hand from her ass and wondered if something was wrong. She simply smiled at me, lifted her dress up again with one hand and held the crotch of her panties aside with the other, asking "Would you like a taste, Danny?"
And to think, I actually believed we were going downstairs to play a video game.
I soaked in the view of my wanton sister and noticed the moist, full labia now as she continued to spread her cunt wide open and strum her clit. Of course, I couldn't pass up such an offer so I knelt between her legs and pulled the panties down her legs until she lifted each foot long enough to let them fall to the floor. She stepped back a bit until her ass was touching the top of the sofa again; her open pussy hung off the edge and her feet were dangling just above the floor. I dove into her snatch and began licking and sucking the juices that were already starting to trickle out her deep pink groove. I inserted my tongue up her vagina as far as it could reach; Chrissy threw her head back and was savoring the action of my mouth.
