My Slutty Step-Sister

It had been just over three weeks since my step-sister Jenna arrived home for summer vacation, and we hadn't stopped fucking since. The only time we managed to keep our hands off of each other was when we were eating or sleeping. Not only did we fuck all the time, but we fucked everywhere in the house; my room, her room, the kitchen, the living room, even our parent's room. In fact, the only place we hadn't fucked was in the pool. I think the only reason we hadn't done it there was because we were both concerned about our neighbours hearing or seeing something that would reveal our taboo relationship.

Aside from eating, sleeping, and fucking, we had both gotten summer jobs. I was working part time as a personal trainer at the local gym, and giving one-on-one training sessions to help supplement my income. It was only a ten minute walk from the house, so I didn't need to spend money on gas; plus it was good for the environment. Jenna got a job working at one of the lingerie shops in town. It was also part time, but that was only because she scheduled her work hours with mine - for obvious reasons.

Initially, Jenna and I were only supposed to spend two weeks alone before my parents returned from my step-father's business dealings. However, he had done such a good job, his boss asked him to help out with two other deals that his company wanted. They had to spend an extra week away from home, but Jenna and I didn't complain. We made the most of that week. I probably came more in those last seven days than in my entire life. That all ended two days ago when my parents returned home.

My mom and step-father arrived home early Monday morning. Thankfully they had called Sunday evening to let Jenna and I know that they would be getting home around three or four in the morning. Jenna and I had planned to spend the night fucking in their room. Having our parents catch us in that position, in their bed, would have spelt trouble. Instead, we had mind-blowing sex on the pool table in the recreation room. It's a staple in most porn movies, and we had both been dying to try it out. Fortunately, we managed not to stain the green felt.

Anyway, since that night two days ago, there had been no sex. Jenna would often give me 'that' look, but only to tease me. Before our parents came back, she told me that I wasn't allowed to masturbate; only she was allowed to make me cum. I told her that the same applied to her. Since then, she had been taunting me, looking at me seductively, or bending over in front of me. I knew it turned her on even more than it did me, and since it drove me crazy, I could just imagine how horny it made her. I seriously began contemplating ways to fuck her, but with our parents home, there was no way we'd be able to pull it off, especially since our parents wanted to spend every waking moment with Jenna. I didn't mind to be honest. It allowed me to get some much needed rest, plus I had booked extra hours at the gym. I figured I would get out of the house as much as possible for now. It's easier to resist temptation that way.

Our half-sister Hannah was scheduled to return home on Friday. She had finished her summer course and had to write the exam Thursday morning. The earliest flight home she could get was early Friday morning. My step-father was going to pick her up at the airport. I had hoped that my mom would join him, that way Jenna and I would have a few hours alone, but my mom wanted to take her shopping. They would be back before Hannah arrived so that ruled out any possible rendezvous.

I had been asking Jenna how she planned to get Hannah to join our escapades, but she refused to tell me anything. She kept telling me not to worry about it; she had it all planned out and when the time was ready, she would tell me her plan. Jenna assured me that I was a very important part of our planned seduction, but I wondered just how important; was I even necessary? I had stopped asking after she told me not to worry about it for the third time. Now that Hannah was coming home Friday, I was a little concerned.

I woke up Friday morning to the sound of my step-father yelling that he was going to pick Hannah up from the airport. I could hear my mom and Jenna respond, but I couldn't make out what they had said. My alarm clock told me it was just after 8:30am. Hoping to catch another hour or so of sleep, I rolled onto my stomach and buried my face in the pillow. I was just drifting off to sleep when I felt someone lay down on my back. I knew it was Jenna even before she spoke.

"Are you awake sleepy-head?" she whispered playfully into my ear.

"Now I am, no thanks to you."

Jenna giggled and I felt her rubbing her body against my back. "You are so comfortable," she sighed. "I tried to get Mom to go with Dad but she is dead set on taking me shopping. It's too bad," she continued, "cause I'm so fucking horny! I can't wait to feel your cock inside me."

"Keep that up and you won't have to wait long," I responded.

"Hmmmmm... I don't think Mom or Dad would be impressed with that kind of behaviour between their step-children," Jenna purred as she rubbed her hips against my ass.

I could feel my cock getting hard and I knew that if she didn't get to the point soon we'd both lose control. "What do you want Jenna? Or did you just come to tease me?" I asked.

"I did come to tell you something," Jenna said, emphasizing the word 'come,' "but now that I'm here, I just want to tease you. I know you like it when your step-sister teases you." Jenna started sucking on my earlobe. Her touch was driving me crazy. I quickly rolled onto my back. Jenna was now face to face with me, her hair hanging down around both our faces. My cock was now pressing against her and the corner of her mouth curled upward into a half-smile. Her hips began sliding up and down against my hard cock.

I slid my hands down her sides and squeezed her ass. "What is it you came to tell me?" I whispered, our lips almost touching.

Jenna moaned in her throat, her hips still rubbing against my hard cock. "I want you so fuckin bad Bro," she whispered. "My pussy has been so wet since Mom and Dad came home, and it's driving me crazy." Jenna's eyes shined with lust. Her hips began to move faster against my cock. I could feel the heat from the friction. "Fuck me right now," she whispered, "and don't stop until I cum."

Our mother's voice suddenly called up the stairs. "Jenna! Are you ready yet? Hurry up!" The sound of our mother's voice shocked us back into reality. My heart was pounding in my chest. Jenna looked at me, her eyes were clear, yet I could see a glimmer of fear in them. At least it wasn't just me.

"When Hannah comes home, make sure you touch her a lot, like hugs and stuff. And leave a porn movie in my room. Just hide it under my pillow. I'll explain the rest later!" The words came out of Jenna's mouth in a torrent, and I didn't actually understand what she had said until she had finished, but by then she was already out of my bed and in the doorway. "Remember, lots of hugs and touches! Watch how I touch her and do the same." With those last words, Jenna disappeared from my doorway. I could hear her going down the stairs and telling our mom that she was looking for her sunglasses. She thought they were in her room. I heard my mom say that they were in the car and that Jenna had left them there purposely so she wouldn't forget them. As they left, I could hear our mom ask Jenna why her skin was so flushed. The door closed and I missed her response. I would have liked to have heard it myself. I laid in bed for another twenty minutes, trying to get rid of the massive hard-on that Jenna had given me. I considered jerking off, but I had a feeling that Jenna would know if I did. It was probably best to wait, despite how uncomfortable it was. I climbed out of bed and had a cold shower. It had the desired effect. In fact, the water was so cold my skin went numb. After my shower, I picked out one of my porn movies and hid the DVD under Jenna's pillow. I had no idea why she wanted it, but I had a feeling I would find out soon enough.

I went downstairs and ate a quick breakfast. I decided to go to the gym and work out some of this morning's sexual energy. I needed to tire myself out somehow; otherwise the rest of the day would be torturous. I left for the gym just after 10am and worked out until noon. By that point I was exhausted and could barely move. I took my time walking home, breathing in the warm air and enjoying the heat of the sun on my skin. As I approached the house, I saw my mother's car in the driveway. Her and Jenna must be back from shopping I thought. I went inside and could hear the television in the living room. I walked into the living room and my mom and step-sister were busy watching TV.

"Where have you been?" my mother asked.

"Yeah, where were you?" Jenna echoed.

"Just at the gym," I responded. "I thought I would go lift some weights."

"Oh! You should have left a note," my mom said, her voice with a hint of surprise in it. I go to the gym every day and would have expected her to think it was a normal part of my day by now. "We thought maybe you had been abducted or something... well, that's what Jenna thought anyway," my mother continued, throwing a glance at Jenna.

"I thought it was a definite possibility," said Jenna, "but I should have known you were at the gym. You have to keep all your muscles big and hard," she teased, "otherwise the girls will stop talking to you."

I instantly picked up her innuendo about my muscles and couldn't help but smile. The look in her eyes told me that she knew what I was thinking. I knew better than to continue this line of discussion with my mom in the room. I didn't want her to pickup on the possible flirtation between Jenna and I. "I'm going to make myself lunch," I said as I turned to go to the kitchen.

"I'll do that for you," our mom said, starting to stand up.

"I'm quite capable of making myself lunch Mom," I sighed. "I don't need it done for me." Being independent was my favourite thing about living away from home. I hated when my parents babied me. Plus, I didn't want to be alone with Jenna until my parents left. I quickly warmed up some chicken breasts that I prepared the other day. As I sat down at the table to eat, my mom entered the room. She started telling me about the shopping trip. I wasn't too interested so I nodded and made one word responses at the proper places.

A few minutes later, Jenna came bouncing into the kitchen. "Hey, thanks for the CD Bro! It's exactly what I wanted!" Jenna hugged me from behind and gave me a big kiss on the cheek. I almost choked on my chicken.

"What CD?" my mother inquired.

"Oh, just some relaxation music that I can listen to at night to help me fall asleep. I've been pretty restless the last few days," Jenna responded happily. "You are the best Bro ever!" Jenna teased. It sounded like she was talking to a puppy or some other cute little animal. Having her this close was making me hard, so I tried to focus on eating.

"Why do you always call him 'Bro', Jenna?" my mother asked. "He does have a name."

"Because he likes it; right Bro?" Jenna was smiling at me, her arms still wrapped around me.

"It depends on the situation," I said tactfully. "It doesn't bother me as much as it used to." I gave a sideways glance to Jenna, and we both smiled knowingly.

"I'll never understand the two of you," our mom sighed, exasperated, "but at least the two of you are getting along. Remember when you both started high school. All you did was yell and scream at each other."

"We still yell and scream at each other," Jenna said, "but only because we love each other; right Bro?" Her voice was heavy with sarcasm, but I could detect the truth under it. Jenna's comments were dangerously close to giving us away. I could see a slight look of confusion on my mom's face, like she was trying to decipher Jenna's tone, as well as the words. I was just about to say something when the front door opened and the voices of Hannah and my step-dad filled the house. Our mother's look of confusion quickly dissolved into one of happiness, and she quickly turned and went to see them.

"Don't forget what I told you about Hannah! Make sure you touch her a lot! Pay attention to what I do, and do it too!" Jenna quickly whispered to me. Then she ran out of the room to welcome our half-sister home. I shoved the remains of my lunch into my mouth and swallowed quickly as I got up to join them.

As I entered the foyer, my mom was hugging Hannah tightly and crying a bit as she told her how happy she was to see her. Hannah was patting my mother's back and trying to console her, but also trying to extricate herself from my mother's grip.

"Hey sis! It's good to see you!" Jenna exclaimed as she hugged Hannah.

"It's good to see you too Jenna!" Hannah exclaimed. "It's been a while!" Hannah looked genuinely happy, but whether it was to see Jenna or just to be free of my mother's soul crushing hug, I'm not sure.

"Wow! Look at the tummy on you!" Jenna said, poking Hannah in the stomach with her finger. "All those sit-ups are working!"

Hannah laughed. "Coach makes us do 250 every day. She says that cheerleaders have to be in excellent shape. I hate doing it, but I like the results," Hannah smiled.

Seeing Hannah beside Jenna, I was struck by their differences. While Jenna had long black hair, dark tanned skin, and perky breasts, Hannah had shoulder length bleached blonde hair, pale milky skin, and large heavy breasts. I figured they were a large c-cup, or possibly a small d-cup. She looked very similar to our mother. Hannah and our mom could pass for sisters. The only real difference was our mom had larger breasts - 34DD. I had checked the size on one of her bras once. I was curious and a teenager at the time. Hannah was also a few inches shorter than Jenna. However, they had the same sharp facial features. Their cheekbones, noses, and mouths were almost exactly alike. Only their eyes differed. Jenna had dark green eyes like myself, while Hannah had bright blue eyes. My mother also had green eyes, but hers were a brighter shade of green.

I walked up beside Jenna. "Long time no see!" I joked. Hannah laughed, and I hugged her. She seemed very surprised, probably because the only time I hug her is on Christmas or our birthdays. Her reaction only lasted a second, and then she hugged me back. As I hugged her, I made sure it was a tight hug, pulling her body against mine. I also made sure I rubbed my hand up and down her back. I ended the hug and pivoted to Hannah's side, keeping my arm around her waist. "I hope your luggage is light," I said to her. "I just got back from the gym and I don't know if I can carry anything heavy."

"You'll have trouble with her things then," my step-dad said. "I think she packed her whole dorm room into her bags!"

"Whatever Dad!" Hannah laughed. "You're just getting old!"

"You're right about that! I've exhausted myself enough with your luggage for today. Your brother can take your things up to your room," he said, clapping me on the back. "Have fun with that!" All three women laughed, but only Jenna winked at me.

Hannah's luggage wasn't as heavy as I thought it would be, but I could only carry one piece at a time. I dropped the third and last piece on her bed and collapsed onto it. "Thanks for all your help," I said sarcastically to the girls while I stared at the ceiling. They both ignored me. They had both gone up to Hannah's room while I brought her luggage in. I noticed Jenna was touching Hannah quite a bit. It was all innocent however, touching her arm and shoulder, or poking her in the side. Hannah reciprocated, apparently thinking nothing of it. I watched them for a few minutes while I continued to lay on Hannah's bed. Finally, I stood up and started walking out of Hannah's room.

"Aren't you going to say bye?" Jenna teased. I could tell that while her tone was teasing, the look on her face was serious. She wanted me to touch Hannah again.

"Well, I can't even get a thank-you hug for bringing all these things in, so why should I?" I said.

"Awwww... I'm sorry!" Hannah said, her arms outstretched as she came up to me. "Jenna and I were just so caught up in our conversation, I wasn't thinking." Hannah threw her arms around me and I hugged her back.

"It's okay. I was going to take your luggage back out to the car if you didn't thank me," I teased. Jenna was making a kissy face at me. At first I didn't know what she was trying to say, then I realized she wanted me to kiss Hannah. "Where?" I mouthed back.

"Anywhere," Jenna mouthed silently. "Kiss her forehead or something!" Jenna rolled her eyes and shrugged her shoulders at my complete inadequacy.

I kissed Hannah on the forehead and said, "It's good to see you again Hannah. And watch out for Jenna. She's trouble!"

"Oh whatever!" Jenna said, her voice raising slightly. Hannah laughed with me. I kissed her again on the forehead and left the room. I could see a slight smile of satisfaction on Jenna's face. I guess I had done well.

That night at dinner our parents told us that they would be leaving again for business. They would leave Monday morning and would be gone for a month. Jenna stole a quick glance at me and smiled. I couldn't wait for our parents to leave. Over the next few days I made sure to increase the amount I touched Hannah. Sometimes I'd innocently touch her arm or hug her, other times I'd tickle her or touch her leg. Jenna had actually grabbed Hannah's breasts and ass a few times saying how jealous she was that she didn't have boobs as big or as tight an ass. Hannah would laugh and grab Jenna's boobs back, usually saying that her's were very perky and she'd rather have perky breasts. It happened twice while I was in the room, and from what Jenna said, once when our mom was in the room. Since Hannah played along, Jenna said it was a good sign.

Our parents left just after 10am on Monday, and my sisters and I saw them off. After the door had closed behind them, Jenna winked at me and mouthed the word 'tonight.' I still wasn't completely sure what Jenna's plan was, but I had deduced that our constant touching of Hannah was what the girls would do at St. Mary's when they planned on seducing a new girl.

Jenna and I both had to work at noon and wouldn't be home until 5pm. Hannah had the house to herself, but she decided to go see a movie since she didn't want to be home alone. According to her, the other people in the theatre made her feel like she was doing something. Work for me was rather difficult. It usually kept my mind occupied and away from thoughts involving Jenna, but the anticipation regarding tonight was too much for me to ignore. I just hoped that the seduction of our sister would succeed; not just because I wanted to fuck her, but because if it failed Jenna and I would have a huge mess on our hands, and I don't think we'd be able to handle the damage control. The only thing that kept these dark thoughts at bay was that Hannah had responded positively to all the touching Jenna and I did. Of course, that didn't necessarily mean she would respond to our sexual advances, but it was better than nothing.

After work, Jenna and I arrived home almost simultaneously. Minutes after I entered the door, Jenna came in behind me. It would usually take her longer to get home, so I figured she must be as excited as I was. Hannah had prepared a surprise dinner for us, fish with some kind of fruit sauce. It was actually pretty good. Even Jenna was honestly surprised by how tasty it was. After dinner, the girls told me to pick a movie to watch from Hannah's DVD collection while they did the dishes and made popcorn. Unfortunately, there wasn't much to choose from. I swear Hannah had every chick flick and romantic comedy ever made. I picked the one that had the best looking women in it and brought it down. Apparently I had taken longer than I thought because the girls were done with the dishes and were sitting on the couch eating popcorn. They were busy laughing at some TV show and didn't mention how long I took. I put the movie on and Jenna patted the seat between her and Hannah. There wasn't much room and I found myself packed in tightly between the two girls. Jenna draped her legs across mine and Hannah did the same, making a joke about me being a good foot stool. Jenna laughed and told her that I was good for a few other things too. I grinned at her and she winked and smiled back mischievously.
