My younger sister is 5' 4", about 105 lbs, naturally blonde with c cup breasts and light blue eyes. I am the older sibling by about 5 minutes and the only way to tell us apart is by our personalities. Being the older one, I'm more reserved and conservative where she is more out going, bubbly, and more of a risk taker.
People would wonder which one of the sisters each of us were and we enjoyed making it more difficult for them to guess during our entire lives! When they guessed correctly, it was always because Jackie seemed more happy and lively than me which taught us how to better imitate each other.
When we wore the same exact clothes, and did our hair the same, our mannerisms were already similar, so she would just calmed down a little and I would act more bubbly to fool them and cause them to usually pick the wrong one.
This came in handy since I was better at Math and Jackie in English, so we even seemed to always get the same grades in school! We could cover for each other's boyfriends too and learned to kiss the same and learned to act like the other with what we liked to do.
We grew up as close as two sisters could be & I married first settling down with Tom after college while Jackie was still enjoying her sexual freedom. We talked and usually visited every day discussing what we liked and didn't like about our lives.
I missed the sexual freedom that she was enjoying so after I'd been married for about a year, we decided that she could take my place with Tom for an evening once in awhile so that I could experience the free life that she had. She always liked Tom and was also anxious to live the domestic life once in awhile and just relax with Tom for an evening.
Some of the parties that she had agreed to go to were so wild that I could have never imagined if I hadn't lived it. Then, the next night I would be back home fixing Tom's dinner and snuggling with him before we went to bed and he'd fuck my sore pussy that had been overly used during the wild party the previous night! He never suspected and my sister and I would go over all of the details.
Even though Jackie had finished college and had a good job, she still liked to dance for men at a strip club in the city. She liked the excitement but I was always nervous to take her place. It was exciting to shake my booty for all of those horny men while she kept Tom happy at home. She said that she liked the slower passionate sex with Tom who loved to kiss almost the whole time while he was fucking.
I liked the animal sex that she had usually arranged while working or when she was getting off at 2 am. I'd let strangers feel me up and during the private lap dances, even letting them finger me. I told guys that I'd meet them in the alley behind the club during my break, and give them a quick blow job as I knelt in the dark by the dirty garbage container during my smoke break!
At closing time, there were always a group of guys waiting outside in the parking lot who wanted to take me home with them. This was my time, and I liked to pick a group of 3 or 4 to go to their place and fuck for the rest of the night.
On one such occasion, it gave me the chance to try double penetration as I rode one guy while another moved behind me and took my ass. I could only imagine how wild Jackie was during those occasions, because even I couldn't help but scream out from the pleasure of being fucked by two stiff ones at the same time!
Tom and I had never tried anal and it was just a few month before that I had tried it for the first time with one of Jackie's dates. He broke in my ass and now I was learning how to use it just like Jackie had described.
Eventually, Jackie married a cop named Phil and they led an open swinging kind of lifestyle. Phil had a really big dick and loved to fuck really hard and rough getting me off so many times in a row that I once cried out Tom's name before I realized it.
Jackie and I continued to met up almost every day and the four of us would frequently go out to dinner and dancing. Phil and Jackie would sometime start to make out in front of Tom and me and Tom's boner told me how much he liked watching Jackie. I'm sure that he always wanted to fuck my sister! He didn't realize it, but he had!
Tom and I would remain more calm and usually just kiss and feel each other up through our clothes as we watched them. Jackie would look at Tom while they were doing things and Tom was all but drooling and I wanted to do that to him.
Jackie and I wore the same perfume and so one night after dinner when we went out to dance, we decided to swap so that I could fuck Phil in front of my husband without him knowing that it was me.
Everyone had drank quite a bit before Jackie and I went to the restroom and swapped out clothes. I sat down next to Phil when we returned and rested my hand on the big boner in his pants as Jackie and my husband talked and kissed lightly.
It didn't take long for Phil to have his hand up my skirt and my panties off. I watched Tom and Jackie giggling as they talked while Phil was fingering my wet pussy. I came on his fingers while Tom looked over at me with that familiar smile on his face telling me that he knew what Phil was doing.
Phil moved me over onto his lap and I groaned as his big dick stretched my vagina while I was leaning forward with my elbows on the table watching my sister and husband act as Tom and I usually do when they're going out of control.
My breasts were bouncing against my thin top as Tom looked at them while Phil fucked me and he looked up into the lust in my eyes as I continued to watch his. Jackie's arm was moving a little beneath the table as she was rubbing my husband while trying to contain herself to act more like me.
Jackie smiled at me knowing how much I was enjoying myself and with my eyes closed tightly, after being fixed with Tom's, as I came on Phil's big hard dick. I was shuddering and panting trying not to scream out in the public place as my vagina grabbed tightly around my sister's husband's fat hard cock. When I opened my eyes, I could see Tom smiling to the erotic performance I had just given him.
I felt his eyes all the way down to my slick vagina stretched tightly around the big hard thrusting cock and it quickly sent me into another orgasm. I had to sit up and grunt as quietly as I could while my hips humped Phil's beautiful hard cock and I had to look up away from my husbands horny eyes.
Phil's hands both went up inside my top grabbing my breasts and squeezing them causing my nipples to protrude even more against my thin top as Tom watched. I looked back down at his smiling eyes as my vagina was still cumming on my sister's husband's hard dick while her hand was moving more beneath the table on my own husband.
Phil quickly pushed me off of his lap onto the seat between him and Tom and pulled my head down into his lap. Hidden by the table I took the fat head of his big dick between my lips and began sucking him off as he moved my mouth faster on him with his tight hold of my hair.
My pussy was still grabbing for a hard dick, but there was nothing there as my hips continued to hump into the cool air. I felt my skirt up around my waist and the cool air against my bare bottom made me imagine Tom's eyes fixed on it and my thighs as my sister continued to jack him off.
Phil's warm cum hit the back of my throat and I quickly swallowed it ready for the next stream as I spread my knees apart hoping that Tom could now see my quivering pussy grabbing for something! I started cumming again and reached down to rub my clit fast as I swallowed more and more of Phil's warm sperm.
My hips were still humping my hand as Phil held my head still with his spent cock filling my mouth. I moved my hand from between my legs hoping that Tom could see my horniness still humping while I licked Phil's hard shaft held deep in my mouth and pushed my face down further taking him into my freshly coated throat.
Phil made an exhalation noise as he released his hold of my hair and I backed my mouth up off of him a little as I coughed around his still hard dick before swallowing more of his load. I could once again begin hearing the crowd and music in the club as I pulled my mouth up off of Phil feeling some of his sperm dribble onto my bottom lip.
I resisted the urge to lick his cum off of my lip and sat up to look at my husband's eyes watching me. His eyes went from mine down to see the dribble of sperm on my bottom lip and back to my eyes as he began groaning and moving around while my sister leaned her head down into his lap.
I could see in his eyes that he was cumming in my sister's mouth and while looking at him, I opened my mouth a little showing him my cum coated tongue as I licked my bottom lip and then swallowed. I could just see the top of Jackie's head bobbing up and back down quickly as she was taking my husband's load.
Phil's hand moved my face towards his as his lips moved up against mine and I remembered my sister saying that he liked to kiss after cumming in her mouth. I opened my mouth wider for his tongue to explore my sperm coated mouth as I could hear my husband's groans as he was continuing to ejaculate inside of my sister!
Phil groaned as he cleaned the inside of my mouth swallowing what he gotten and when our lips parted, I looked back at Tom to see him looking down embarrassed as he was putting away his spent dick. I glanced at my sister smiling as she was still swallowing his load and licking her lips clean.
The guys went to the bathroom and I slid over to tell Jackie that it was so amazing being her. She giggled and said that she had fun too and how did we want to play it tonight. I told her that it was up to her of who she wanted to go home with.
Jackie said that they were going to a swinging party at a friend's house later and that she really wanted to get fucked a few times. I tried to act happy for her as we went to the restroom to change back into our own clothes, but I really would have liked to have been her for the rest of the night and have my pussy slammed over and over again!
We got back to the table and I slid in next to my husband kissing him and wondering if her could taste Phil's residual sperm still in my mouth. It made my pussy tingle and I squeezed my legs tightly together!
We got home and got ready for bed, but I only pretended to brush my teeth wanting to keep Phil's sperm coating in my mouth. Tom was still horny from watching who he thought was my sister and Phil and commented on how many times it appeared like she had cum.
I kissed his lips softly and said that he seemed to have cum a lot too and that got him going as his tongue forced inside my mouth. Tom was rolling over on top of me and I reached down to push his shorts down as I spread my legs wide for him.
My pussy was so wet that he slid easily inside of my horny used vagina and I groaned into his mouth as his tongue licked up Phil's sperm that I had saved for him. He began fucking me harder and faster than usual obviously thinking about my sister as my orgasm began just as quick.
I came on my husband's hard dick as it penetrated my vagina over and over again that had just been stretched tightly around my sister's husband's fat hard dick! Tom came quickly too, filling me up as I humped his hard cock while tasting his hungry mouth.
I met Jackie for lunch the next day and she told me all about the party that they had gone too. It sounded like so much fun that I had missed out on, but it was, after all, her life! She said that they had met a group who had all agreed to be tested and then to only fuck each other so that they could safely have a cum party.
I really liked the sound of a cum party and my mind began wondering when I'd have a chance to be her at one of those. The part that she described that I wasn't sure about, was that after Phil had noticed her pussy dripping with other men's sperm, he liked to tie her face down and spank her as another woman blew him.
I told her my concerns and she said that it wasn't that bad! Even though he used a belt, he only spanked her five times and then let one of the other guy's fuck her. Then he'd spanked her five more as the other man's sperm ran out of her. Once he came in another woman's mouth, the spankings stopped and the other guys set her free.
She said that the dark room was amazing with naked people everywhere fucking and sucking and swapping sperm until you had enough and crawled towards the light shining from under the door. I was so wet by the time Jackie had finished describing it to me, that I went into the bedroom and rubbed a big one out.
