I can't really believe this happened the way it did, but there is no complaints from me. It started with a vacation weekend in a city we were looking to explore. My wife (Jamie) and I had decided to take a vacation in a city away from our own to explore it, and it just so happened that the events would get a lot more complicated than that.
Let me start be telling you I am 37 years old, and a good looking guy if I don't say so myself. I am 6'1" tall and weigh around 205 lbs. I have dirty blonde hair, with hazel eyes. My wife is around 5'7" tall, blonde hair, blue eyes, and very curvy, with a 36 DD, and a 30 inch waist. My wife is by no means fat, but she is not skinny either. To me and most other guys she is very beautiful.
For several weeks now my wife has been dealing with her sister's divorce. Her older sister was going through a very nasty divorce where her husband was basically trying to take her to the bank. My wife decided it would be a good time for her sister to get away and took her on the vacation with us. Instead of getting two separate hotel rooms we got one with two queen size beds. The story begins here.
My wife's sister, Kristy, is my age being one year older than her sister. Kristy is about 5'7" tall, with red hair, blue eyes, and a very slim figure. Kristy has many times entered my thoughts in our ten year marriage. I would never try anything with her sister, but have had many sexual thoughts along those lines. I had even caught myself getting a hard on when I would see her in her bikini during the summer. Her husband never had sex with her and I got to hear all about it from my wife.
Our first night in Pittsburgh, the city we had traveled to for our exploration vacation, was uneventful after having a long day traveling. We went to the restaurant beside our hotel ate some dinner, and had a few drinks watching the baseball game on the lounge TV. We talked briefly avoiding the divorce conversation and then headed to the hotel. Kristy went directly to the bathroom and took a shower.
While Kristy was out of the picture my wife attacked me ripping at my clothes trying to obviously get a quickie before her sister got out of the shower. She pulled my zipper down and fished around in my pants pulling my thickening cock through the fly of my boxers and out into the air.
"MMMM!" She purred as she sank to her knees in front of me.
In no time at all my wife had my proud eight inches standing straight up and thickening with every lick of her tongue. She was pushing my cock against my abdomen and licking it from the base to the underside of the head. Over and over her tongue licked up the length of my cock like it was an ice-cream cone. Occasionally she would take the head into her mouth and lightly nibble on it. I reached down and captured my wife's head in my hands and slowly fed my cock about half way into her mouth.
"MMMMM!"
"You like that? You like it when I fuck your cute little mouth?" I asked her as I began to slide my cock in and out of her mouth. Suddenly the shower turned off. My wife jumped up and started going through her bag. She reached out and stroked my cock twice and said. "You better put that thing away."
"ARGHHH YOU have to be kidding me?" I scolded.
"Now, Now my sister will be out in a minute." My wife whispered as she continued to stroke my cock.
I ripped my cock from her hand and shoved it into my pants. I could forget putting it in my boxers right now, so I shoved it down the leg of my pants and sat down on the bed leaning over so my bulge could not be seen when Kristy emerged.
As Kristy emerged from the bathroom in a robe, my wife ran in right behind her. I watched as Kristy lightly dried her beautiful red hair with her back turned to me. I could see the globes of her ass dancing under her sheer robe as she dried her hair. My cock was not losing any blood any time soon. I tried to take my attention to the TV and finish watching the game, but Kristy came and sat right beside me.
"Who's winning?" Kristy asked.
"I truly have no idea, just watching." I replied laughing.
"How do you watch a game and not know who is winning?" She asked.
"Well!" I thought about telling her the truth but decided against it. "I just watch the action and have paid no attention to the actual score yet." I said laughing.
Kristy lay back on the bed beside me, and her robe rode up her thighs to just below the V of heaven. I thought if I leaned slightly forward I would be able to see everything as clearly as if she was laying there naked. Kristy yawned and slightly moved her legs apart. My cock was regaining some of the blood it had lost.
About this time the shower started back up and I knew my wife was getting ready to get in.
"You should go join her." Kristy said.
"What?" I asked.
"You should go join her she might be able to do something with that huge bulge you're trying to hide form me." Kristy said with her eyes closed.
I felt my face flush with the knowing she had seen me sitting here with my hardon.
"Excuse me?" I asked flabbergasted.
"Well it is not like you can hide that whole thing, it is very obvious what you are doing bent over like that." Kristy said with a smile.
I swung my leg over her very quickly, and was now straddling her with my hard cock resting in the cleavage of her ample breasts.
"Now what smart ass?" I asked laughing at her.
This is when Kristy did something I never would have suspected and it changed our relationship forever.
Kristy reached forward with her neck and nibbled the head of my cock through my pants. I didn't stop her, as a matter of fact I pushed forward trying to get more of my cock into her mouth.
"Now! Now! Big Boy, you better get up before Jamie gets done in the shower. How would you explain this?" She smiled licking the head of my cock through my pants.
She was correct and I knew it so I swung my leg over her and stood up beside the bed. Kristy reached out and grabbed my cock through my pants.
"Good God, Jamie wasn't lying when she said you were big." Kristy said.
"Stop!" I whispered pulling away from her. "Such a tease," I said walking towards the bathroom.
"Who's teasing?" Kristy asked as I reached for the bathroom door handle.
I quickly stripped and opened the shower curtain to see my wife's wet naked body. I needed to fuck, and I needed it now.
I quickly got into the shower and slid my hard cock up between the crack of her ass, as I reached around and fondled her breasts.
"MMMM, I was hoping you would join me." Jamie quietly said.
Jamie quickly reached back and positioned the head of my cock at the entrance to her tight pussy. As I slowly pushed about three inches in, Jamie moaned out. "Oh God, you are so big and hard right now."
"Shhhhh!" I said as I sank another three inches into her damp tightness.
"OH FUCK!" She said pretty loudly.
"Your sister!!" I whispered into her ear.
"OH god Fuck me! I don't care if she hears, you feel so fucking good. FUCK ME!"
I began to slide my cock in and out with long full strokes, slowly at first and gaining speed as she got wetter.
"FUCK YEAH! Fuck me deep with that big hard cock!" Jamie cried out.
I increased my pace and began to slide the whole thing in and out of Jamie's tight pussy. I reached my hand around and began to rotate my fingers around her clit.
"YES, YES, YES That's it baby fuck me!"
I began a quick deep pace until Jamie was crying out and there was no doubt Kristy could hear us through the bathroom door.
I continued this pace up for several minutes, but Kristy kept popping into my mind. I was wondering if she was masturbating listening to her sister cry out. Would she be thinking about my cock sliding in and out of her?
That did it with those thoughts and my wife's tight pussy milking my cock I could hold off no longer. I stopped dead in my tracks to try and delay the reaction I was having.
