Our mom told us that she wanted to visit with her mother who was in an assisted care living facility. Since neither Kelly nor I wanted to go sit around the whole weekend at an old folks’ home we asked if we could stay home. Mom was a little reluctant at first, but dad convinced her, that everything would be okay and that I was more than capable of looking after my sister for two days.
Kelly and I had been sitting around naked in the house one evening after dinner it had been an extremely hot June day and the only way to get comfort was to go naked. Thankfully it had started raining so it had cooled off to the mid 70’s after the sun went. The two of us were sitting watching TV.
“Come with me,” Kelly said standing.
She took my hand and led me outside to the patio. It was lightly raining, I pulled one of the big double loungers out from under the upstairs deck and set it up next and to the pool. All the outside lights were off, the only light was coming through all the windows from the lights we left on in the house.
“Lay back,” Kelly said to me as I could see her long black hair getting wet, along with her sexy body.
I laid back on the lounger as the cool night rain drenched the two of us. Kelly’s long hair was becoming wet and sticking to her naked body as the rain ran over her. She sat on the end of the lounger and started stroking my cock. Once she was getting me hard, she leaned over and sucked my cock into her mouth. After a few minutes and more thunder and lightning I was hard, and we were both soaking wet. The night was still warm even though it was raining.
“You know Kelly, you are a little crazy when you want to do this,” I said.
“I always enjoy this,” Kelly said as she slipped up and straddled my cock. Kelly slowly worked my cock into her pussy as she slowly eased down on my long cock. Our skin was getting cool to the touch, but her insides felt blazing hot as usual. She got all the way down about the time there was a flash of lightning and another clap of thunder. Kelly started to wiggle her hips sensuously.
I watched in the dim light from the house as my sister closed her eyes and dropped her head and just worked her pussy on my cock. Our wet thighs now sliding against each other as she moved. I have always thought that watching sweat or water drip off a woman was one of the sexiest images there was. Now with the rain beginning to fall harder we heard thunder rumbling off in the distance again as the sky lit up occasionally. I watched the trails of water trickle down Kelly’s neck and run over her breasts and drip from her nipples as she worked her hips slowly. I sat mesmerized by this sight as she kept going. Drop after drop of water dripping from each nipple. By the dim light coming from the windows, she looked so incredibly sexy as all the rain ran down her body and dripped off it in strategic places. I felt coolness on my groin despite her heat. I looked down and there was a pool of water forming between her legs and on my groin. I watched the rain trickle down between her breasts and run down and over her stomach in little rivers on its way to where we met, then to fill the growing pool.
“Oh god, this feels sooo… good. Outside at night, in the rain, just working your cock in me as I listen to the rain falling.” She said.
Kelly moaned as she worked my cock deep inside her she wiggled like a very sensuous snake. I held my Kelly’s thighs as she worked her own magic to get her to where she wanted to be. The longer we went the more aroused the two of us became. As our skin cooled, the only heat between us was surrounding my cock. More and more Kelly worked her pussy on my cock as I watched her wiggle in the dim light. She was moaning loudly, and I was enjoying watching her.
“Oh, fuck yes!” Kelly screamed and sped up a little. Thunder and lightning always excited her when we did this in the past. Sometimes I worried that she was being just a bit too dangerous. “Oh, fuck yes, this is so exciting!” Kelly screamed as she worked harder and harder.
I held on to Kelly as she worked toward her orgasm. More lightning flashed in the distance, then the thunder.
“Oh god Keith, I’m coming!” She screamed as she worked her hips faster, then I felt her tense up. A loud moan and few seconds later I felt the warmth of her love juices squirting onto me. “Oh god yes!!”
“Kelly, don’t you think it is time to go back inside?” I asked.
“Oh…not now, I’m just getting started!” Kelly yelled over the thunder. “You know you are a little crazy.” I told her, she just smiled. I held Kelly and stood up then turned and laid her on the lounger. She lifted her legs up and spread them and laid them over the arms of the chair waiting for my cock.
“Keith, please! Do me hard!”
I got between her legs and slowly eased my cock back into her warm pussy. With her lying back now I could see the rain splashing on her face. Her wet hair was stuck to her face as she laid back. I took my hand and pushed the hair away from her face. I held myself up for a few minutes and ran my hands over her wet breasts as the water beaded on them. I ran my hand over her wet lips finally, then leaned down and kissed her for a minute.
“Oh yes Keith! Fuck me!” She screamed. It always seemed her arousal grew as the storms would grow closer.
I held myself up while we looked at each other and then began thrusting my cock into Kelly harder and harder. I knew this was what she desired.
“Oh yes, that’s it!” She screamed.
I worked my cock in and out in long, deep, hard strokes, Kelly was thrusting up to meet each of my thrust. We were both getting more and more aroused as we kept going.
“Ahhhh!! More, more, more!!” Kelly screamed as I felt her arousal growing inside her.
I kept thrusting into Kelly’s pussy. “Fuck me!!” She screamed as I kept driving into her. I would feel her heat, then coolness, then her heat, then coolness. I kept this up for a long time. Kelly was starting to get off again. I could tell she was growing toward another huge orgasm. She wrapped her legs around my waist and pulled me in tight. Kelly started coming, coming hard. She kept screaming as she jerked beneath me. A huge flash of lightning and an immediate burst of thunder.
“Ahhhhhhh!!! I’m coming!!!” She screamed as I felt her orgasm start around my cock and then run through her entire body. “Oh, fuck!!!” She screamed over and over for a minute or more as she trembled beneath me. When her orgasm was about finished, she reached up and grabbed me and pulled me down to lie on top of her. She kissed me for several minutes. She pulled me down and kissed me again to the rumble of thunder. I looked at her face as she stared up into my eyes. A sudden smile grew on her lips.
I got up and Kelly turned over and got up on all fours. About that time there was another flash of lightning and more thunder. The wind had also picked up and was blowing steadily. I grabbed my Kelly’s hips and eased my cock back into her warm pussy. I kept this up as the rain pounded us now and the wind blew harder. Kelly grabbed the arms of the chair to help hold herself up. I slid slowly out and rammed back into her for a few more minutes. She moaned and cried out each time I shoved back inside her. I kept going and started thrusting into her harder and faster. She cried out each time. I held her tight and fucked her hard and fast.
“Oh…my…god Kelly said. She was growing more excited and aroused as she was nearing another huge orgasm. “Ahhhhhh!!!” She screamed as I felt her hot pussy tighten around my swollen cock. I felt Kelly’s pussy begin to squeeze my cock over and over. I knew she was about to explode and come hard. A minute later she screamed.
“Fuck…I’m coming!! Now!!!”
I felt her crush my cock with her strong pussy muscles. The two of us jerked and humped into each other and came together hard for a minute. “Oh my god!! That was great!!” Kelly screamed. We laid on top of each other until a brilliant flash of lightning hit nearby. I held Kelly tight in the breeze. We were cool from being wet and the wind. She wrapped a leg around me and pulled the two of us close together. I held her tighter as she hugged me. We laid for a while then finally went back inside. Kelly led me down to the sunroom and we slipped into the hot tub. She slipped down in the hot water until it was up to her chin.
“Emmmmm,” escaped from her.
I watched Kelly as she tilted her head back against the side of the hot tub and closed her eyes and soaked. After about 30 minutes we both got out and dried off and went upstairs to the bedroom. We both slipped under the sheets on the bed and I turned out the light. I spooned up behind her and held her in the dark. I held her tight and pulled her body close to mine. The warmth of her ass pressing against my cock felt great after being cold. Kelly grabbed my hand and placed it between her breasts. I placed my hand over one of her breasts and felt it. I played with Kelly’s breast for several minutes. I felt her nipple get hard and stand out. Kelly reached back and found my cock and began playing with it. Her hand was warm, and it felt good. The longer we played with each other the more my cock grew. After a few minutes my cock was hard and poking into Kelly’s ass. I slipped my hand down and ran my fingers over her pussy lips.
“You’re already wet,” I said.
“I’m still horny.” she said. Kelly raised her leg and placed it over mine and pulled me to her. “Fuck me again, in your safe warm bed,” she said with a giggle. She held my cock as we worked around until I could slide it into her from behind. She pulled me tighter with her leg as I eased all the way into her pussy from behind. She took her hand and reached around and placed it over my cock and her pussy and felt me slowly begin to slip in and out of her. I held her tight and pushed my cock all the way in and held it there. Kelly was quiet as I kept doing it for a long time. I felt her pull me in tighter with the leg that was wrapped over mine. I knew from experience she would build to a nice strong, but gentle, orgasm. The warmth of her insides and the on and off squeezing of my cock by her strong muscles kept adding to my own arousal. I kept going as Kelly moaned gently. She always felt incredible when we took it nice and slow. I felt her pussy muscles squeeze me as she started to shiver gently. I could feel the gentle waves running through her body as I kept pumping cum into her.
“You feel good,” I whispered in her ear.
“You do too.”
As we finished, I kept holding her and kissing her gently on her shoulder and neck until we both want to sleep.
