Sister in Law Vacation

Things in life can quickly spiral out of control. It all started with my wife's family taking their annual pilgrimage to Canadas Wonderland. It is like Canada's version of Disneyland. Every year the whole family gets together for a week of roller coasters, water park, and over priced food.

We packed up the SUV and headed out in the wee hours of the morning on the three hour drive to get there. Stacey navigated while I drove because driving in Toronto makes her nervous. We arrived at the hotel without incident, minus one missed exit just as we got there. Being the first ones to arrive, we checked in and went up to our room to settle in. The room was far bigger than either of us expected. Apparently we got an upgraded to a suite. There was a lounge area with a pull out couch and a seperate bedroom with a king size bed.

It wasn't too long before Stacey's brother, Jackson and wife showed up with their three kids in tow. They checked in and we all headed down to the pool while we waited for Mom to arrive. The kids were splashing about while the adults sat on the side having a couple of cocktails planning on how to attack the park tomorrow.

"There's Nanny!" Charlotte yelled out.

We all turned to say hello to the matriarch of the family when she walked into the enclosure.

"Hey kiddies." Margaret called out to them. "I've got a little surprise for all of you up in the room. Who wants to go check it out when you're done?"

All the kids were pretty much finished then. They wanted their surprise. The kids quickly climbed out of the pool and dried off.

"Hugs first!" Nanny demanded.

They all piled into the elevator and headed up to the seventh floor. Marg led them to her room and opened the door. The kids led the way into the room.

"Auntie Shauna!" they all yelled in unison running over to her.

Stacey's sister moved away to go to school and hasn't looked back. She got a job at a large airline that has kept her flying around the world constantly. My wife and I haven't seen her in years. Although they were sisters, Stacey and Shauna were completely opposite. Stacey had long dark hair, impressive 42DD breasts and was shy, Shauna had short blonde hair, maybe a C cup if she was lucky, and was quite outgoing.

"I couldn't miss seeing my favourite little ones." she said bending over to hug her neices. "Or you too. Its been too long." now looking at the adults.

Over dinner we all got caught up on the travels to exotic locations Shauna had visited over the years. I was quite intrigued the the adventures that she has been through. All too soon it was time to seperate and head off to our own rooms for the night. Shauna was bunking with Marg since they had two double beds.

The next morning we all met up at our room to grab breakfast and head out to the theme park. Shauna was the last to arrive and looked like crap.

"I didn't get any sleep with the chainsaw over there snoring all night." she explained. "I think that I'll just stay here today and sleep."

The rest of us left and spent the day going on rides acting like kids again. When we got back to the hotel, Shauna was refreshed so we went out for supper at the restaurant in the lobby. As we waited for dessert, the conversation turned to the lack of sleep Shauna got and how to change that.

"Why don't you stay in our room sis? If you don't care Steve. We have the room." Stacey offered. "It'll be like a sleepover like when we were kids."

"We have the extra bed. Its settled." I said.

"I don't want to impose but I don't think if I don't do something I'm afraid the whole week will be wasted. Sure, why not." Shauna smiled.

Jax and his family herded of to their room to get the tired kids into bed so they would be ready for tomorrow's adventure. Marg and Shauna went back to grab her luggage to bring it to our room. Half hour later our new room mate was getting comfortable wih her new surroundings.

The three of us sat around having a couple of drinks reminiscing about their childhood. Stacey started to feel the effects of the alcohol and the sun so she headed off to our room. I had just opened another beer and Shauna had slept all day so I stayed out in the lounge talking with my SIL. She told me about how she loved her job and travelling but how it got lonely. I innocently told her that anybody would die to be with someone as beautiful as her.

"Thanks Steve. I needed to hear that. Now maybe we should get some sleep so we aren't dragging our asses tomorrow." she said as she gave me a kiss on the cheek and walked into the bathroom to change.

I'd never thought of her in a sexual way, but she looked incredible as she disappeared behind the door. She was always that pudgy little sister type but now she had really grown into herself. I finished the last of the beer and closed our bedroom door behind me just as Shauna came back out.

I crawled in beside my wife and slid into cuddle with her. Stacey was facing the other way so I started to spoon with her trying not to wake her. Apparently I failed. Feeling my presence, she pushed her ass back against my crotch. I took that as an invitation and slid my hands up under her loose night shirt feeling those wonderful breasts. She let out a sigh when I pinched and twisted her nipples. Stacey reached behind and felt my now rock hard cock. She turned over and pulled down my boxers releasing it from its confines. Sliding one leg over me, Stacey straddled my legs rubbing my erection against her pussy. I continued to message her tits and tweeking her pointed nipples. She had all the foreplay she could handle and guided my penis into her vagina. I thrusted upward showing my entire cock into her in one motion. Stacey shrieked from the intense sensation.

Putting one hand on her mouth, she slapped me with the other. "Stop it! We don't want to wake Shauna." she whispered.

As we continued, the moans of pleasure got louder and louder until we reminded each other to control the noise. I noticed that the door was slightly ajar now.

"I swear I closed that tight." I informed Stacey.

"Whatever. Guess you didn't. You're not stopping now. I'm almost there. Oh fuck. Keep going. Fuck fuck fuck. Yes!" she whispered loudly falling down on me.

The next thing I remember was the alarm going off on my phone. I could smell the coffee from the other room and gravitated to it. Shauna was sitting on the folded up couch enjoying a cup.

"Smells amazing." I hinted.

"I made plenty. This is one I brought back from Nicaragua. Dark full body blend. Stacey ran out for donuts. We are supposed to meet everyone in the lobby in just about half an hour"

"I'm going to have a quick shower then. Thanks for the coffee."

All cleaned up, the two of us went down the elevator to the lobby where the rest of the family awaited. Our nephews and niece were boncing off the walls wanting to get to the park. We took turns riding the coasters with them until we got to Leviathan. They were a little too scared to try that one. We were about to move on when Shauna grabbed my arm.

"Come on. We'll do this one Steve and meet the rest of you at The Beast." she yelled as she was half way in line already.

We made idle small talk as we waited in line. Topics like my job, the latest entertainment news, and politics came up but I was caught off guard by the next one.

"Great seeing Jax's kids again. You and my sister thinking about having kids?" Shauna asked.

"We talked about trying, when the time is right." I replied moving forward with the line.

"Sounded like you were trying pretty hard last night. I almost came in to save Stacey. Oh, we're next!"

I didn't know how to respond to that. The ride was exciting but not as good as the rush I got knowing Shauna was listening to me making love to my wife. The rest of the day I couldn't help thinking about it and staring at her when she wasn't looking.

That night all I could think about was giving my sister in law another demonstration of my libido. After everyone said their goodnights and went to bed, Stacey and I went into or room and closed the door but I didn't latch it. I started to get frisky with Stacey and she eagerly responded. She grabbed my hands and led them to her ample boosom. I tweeked her nipples and that let the fire in her out. She threw her shirt off and climbed on top of me. Pulling my boxers off she engulfed my penis with her mouth bobbing her head up and down. I couldn't help but moan with pleasure loud enough that I knew it could be heard from the living room. Reaching downwards, I pulled Stacey's panties to the side to give me access to her pussy. She hummed as I played with her vagina sticking my thick fingers inside. Stacey was close to cumming and wanted my cock in her. She climbed up and removed her panties sitting back down on my penis. The previous ventures let my cock slide in easily. Both of us moaned as she bounced up and down. That is when I saw it.

It could only be seen from my vantage point. The closed door slowly opened. The light from the television in the living room revealed a silouhette of a figure standing just outside looking in. Shauna was standing there watching and listening to us fuck. As erotic as that was, what happened next took the cake. I could faintly make out the outline of one of her arm reaching down between her thighs and the other disappearing under her shirt. As my wife ground her insatiable pussy down on my cock, my sister in law was masturbating watching us. I layed there watching as she worked herself over as she looked right into my eyes. The resulting orgasm was the most intense pleasure I think I've ever felt. Stacey and I collapsed with exhaustion and Shauna quietly tip toed back to her bed. Within seconds Stacey was asleep.

I got half dressed and went out to get a "drink" from the refrigerator. Creeping through the door, I could see Shauna in her bed continuing to rub her body. Her one hand was moving at a ferociously pace under the blanket. The other was cupping and massaging her exposed breasts. She arched her back as her breathing quickened. My tired penis was rejuvenated with the erotic show.

'Guessing you enjoyed the show.' I said startling her.

Shauna quickly pulled the covers over her body and face.

'Shit, I'm so sorry. The sound of you two got me so worked up. Please don't tell Stacey'

I figured this might be my only chance.

'You know, you don't have to do that alone. Maybe I could help?'

Shauna peeked out of the blanket looking up at me.

'I saw the way you were looking at me all day. It made me feel sexy and desired. Something I haven't felt in a really long time. But what if Stacey wakes up? She would kill us.' she whispered.

I had an idea, 'The bathroom. The extra door and distance will muffle any sounds.'

'I don't know. I don't want to hurt her.' Shauna said hesitating.

'I don't want to either, but I think we both need this.' I pleaded. 'I won't tell if you don't.'

With that I walked into the bathroom and sat against the vanity for what seemed like an eternity. What have I done? What if she told Stacey? Thirty seconds later I got my answer. I could barely hear the faint sound of footsteps coming towards me. Shauna stood in the doorway with just a loose fitting t-shirt and a pair of pink silk panties. Her nipples were pointing at me through the fabric.

'Promise not to say anything?' she asked.

I quickly replied, 'I'm sure as hell not. Now come here.'

Shauna closed the door behind her quietly turning to locking it. I couldn't wait for her to get to me so I moved in behind her kissing the back of her neck as my hands moved under her shirt grabbing her firm tits as I hug her into me. Her head tilted to the side exposing more of her neck. I switched back and forth from kissing, licking and biting her long neck while massaging her nipples and breasts. I pushed our bodies against the door squeezing them together. Shauna had put one of her hands inside her silk panties and the other was pressed against the door.

'You were right. I did need this. It has been so long. Make me feel like you do to my sister.' she pleaded.

I took a step back and pulled her panties down over her ass. Getting down on my knees, I pulled her hips back until my face was buried deep inside her cheeks. It was a good thing she was holding on to the door or she would have fallen over.

'Holy shit!' she cried out. 'Warn me next time, I don't want to wake her up.' in a quieter tone.

All I could think about is what she meant by "next time" as she moaned from the ass licking i was giving her. Just as I thought she was going to explode from that, I stood up and pulled her to the counter. She scurried up on it and I again took my position on my knees between her legs. I finally had a close up look at my sister-in-law's pussy. Shauna had a small strip of hair neatly trimmed leading down to her vagina. Her pussy lips were swollen eager to be touched. I slowly leaned in and kissed her labia. Shauna leaned her head back and closed her eyes while biting her lip. I used my fingers to pull her lips apart to stick my tongue as far as I could into her canal. The taste of her was more creamy than Stacey, but I could not complain about either of them. Both tastes are delicious.

A few times Shauna would hit her head against the mirror. 'Please just fuck me now. I don't know how much longer I can take this.'

Happy to oblige, I stood up and pulled down my shorts. My penis already had precum dripping off the end. Taking it in my hand, I rubbed the end of it up and down her slit. Her pussy seemed like it was alive trying to catch it as it slid past the opening.

Shauna grabbed my ass pulling me inside her. 'Fucking just do it before we get caught!'

I started pounding in and out of the haven of her cove. Her pussy was so tight it made my cock feel like a monster. I leaned in to kiss her giving her the taste of the mixture of her pussy juice and ass flavour. A few times it slipped out and I grabbed my cock it shoved it back in as quick as possible. Shauna wrapped her legs around my neck locking me in to her and allowing my thrusts to go deeper and deeper into her.

'Fuck, fuck, fuck me, fuck Steve. I'm cumming. Holy fuck, keep going. Fuck. FUCK! I can't take anymore. Fuck. Let me suck you off until you cum.'

Shauna pushed me back with her legs and got off the counter, kissed me again, and got down on her knees. She took my cock in her hands and began to stroke it. Leaning down Shauna licked the bottom of my balls and continued right up the shaft to the tip of the head. Again she got the taste of her own juices off my penis. I grabbed the back of her head pushing it all the way down. She looked up at me as she bobbed. The sight of that was enough to make me lose it. Three more strokes and my cock erupted down the back of her throat.

I pulled up my shorts and gave her another long deep kiss. I could taste the mild flavour of my semen on her tongue.

'Our secret right?' I asked

'I swear.' Shauna replied.

I crept back bed and crawled in with Stacey who was still asleep. The next morning we all woke up and had breakfast together. I could hardly look at Shauna.

Stacey pipped up first, 'You look so great today sis. Refreshed and happy. Whatever you did last night, you should keep doing it.'

Shauna and I just kind of ducked our heads and giggled. I can't wait until she is back in town
