Introduction:

Jamie's little sister Jenny is always teasing Jamie's boyfriend. When she tries that in the shower one day, it may lead to more than she expected

Jamie’s Little Sister, Jenny

Siblings

Jamie and I had been dating for about six months. During the school year, the time we got to spend together was limited. Jamie went to a different school than I did, plus, we were both very active on our sports teams. So, we usually only had maybe one or two nights a week when we could get together.

Now, however, it was summer. We had the better part of almost every day to hang out and do all the things we wanted to do during the school year. We went to the beach. We went hiking. We went to the mall. Trips to amusement parks with all our friends. Concerts. Summer was awesome.

Day to day we fell into a comfortable routine. We would meet up early in the morning and go for a run. Then we would come home, take a shower together and, you can figure the rest out. For the rest of the day, if we hadn’t planned anything, we would lounge by the pool so I could sit there staring at her in her bikini, and maybe get the chance to rub oil on her every few hours. I could never get tired of that.

The only problem with pool days was siblings. My older brother was home from college this summer and when he wasn’t working, he and his idiot friends would be out on the deck acting as obnoxious as they possibly could. None of them had girlfriends, and even if they did, none of them could measure up to Jamie. So, if we hung out at my house, they would be leering at her and making rude comments all day. Needless to say, we spent a lot of time at Jamie’s house instead.

At Jamie’s house, we had to deal with her little sister, Jenny. Jenny was cute. A high school freshman now and all full of herself. She looked a lot like Jamie. Blond hair, blue eyes, a little shorter than Jamie, a little rounder in the cheeks, but anyone could pick them out as sisters in a room full of people.

Like my brother, Jenny would always have all of her friends hanging around too, although I didn’t really mind her friends. Jenny’s friends were all a lot better looking than any of my brother’s friends, and I didn’t mind talking with them, even when they got all flirty and giggly.

Jamie used to get mad at me for teasing them, but I was having fun and it wasn’t hurting anybody so I just kept on doing it anyway. I flirted with them but I never would have actually done anything with any of them. I had Jamie for that. Everything I said to any of them was intended as, “hey, guess what I’m going to do to Jamie as soon as you all leave?” And they all knew it. That didn’t stop them from dreaming it could actually happen to them. I could see it in their eyes.

Jenny was the worst. She was always staring at me, making comments, asking provocative questions, or even just outright grabbing my ass. I couldn’t even count the number of times Jenny “accidentally” bumped into me, her hand or her ass would brush right up against my crotch. Jamie’s reaction was usually…

“Please, she wouldn’t know what to do if you gave her directions”

That always pissed Jenny off.

Our morning ritual

One morning, after our run, when we got back to Jamie’s house, she was especially horny. For some reason, she couldn’t even wait to get in the shower. She wanted to fuck. Right now. So, who was I to argue with that?

We knew her parents were both at work, which is why we always came to her house in the first place. She gave a quick shout to make sure her sister wasn’t around. Once she was satisfied that we were alone, she pulled me into her room and threw me on her bed.

She climbed on top of me and attacked in her usual fashion, hands and lips everywhere. I couldn’t pull her top off fast enough. This continued until we decided that the rest of our clothes were just in the way. She climbed off me and we both stripped.

Once naked, she put me back in my place and resumed her position on top of me, that was her favorite. She straddled my belly and pushed her tits down in my face. She loved it when I licked and nibbled and sucked on her nipples. It always made her squeal in delight. Of course, that might also have been from my hands that had slipped down between her legs and started going to work on her clit.

As horny as she was, it didn’t take long to drive her libido off the charts. She pulled my hands out of the way, threw her head back and gritted her teeth as she drove herself hard onto my cock. I grabbed her hips and pulled her down even harder with every thrust. Her hips were gyrating and grinding, getting as much pressure as she could against her clit.

Finally, she let out a scream and her entire body tensed and tightened. Her knees and everything else squeezed my hips, and every muscle in her body seemed to seize my cock. Her juices started to flow, soaking both of us.

When she finally relaxed, she collapsed on top of me and let out a long sigh. That was fine for her, but I wasn’t finished yet. I rolled her over and started to pump at my pace, fast and hard! She grunted with every thrust. I pulled her legs up to my shoulders and drove into her until I was ready to blow. I leaned down, buried my head in her neck and pushed myself all the way into her. Then I blasted her with everything I had. Thank god she’d gotten on birth control.

We both collapsed on her bed, sweaty and exhausted, but totally satisfied. I lay there just staring at her sweaty, sexy body. In no time at all, I was getting hard again already.



Shower time - Jamie

Just as Jamie decide now was the time for that shower, we heard Jenny come in the front door like a hurricane. There was no doubt she was home. That nixed the idea of showering together. Jenny could be a little snitch and Jamie didn’t want her ratting us out to her parents. Jamie seemed to think that Jenny had no idea what we did when she wasn’t around. I didn’t know if that was true, but whatever Jamie wanted, I usually went along with.

While Jamie jumped in the shower, I pulled on a pair of shorts, plopped on the couch in the den and turned on the TV. Seconds later Jenny came crashing into the room. Both Jamie’s and Jenny’s bedrooms, as well as the Bathroom, were all off of the den.

As soon as she caught sight of me sitting there, Jenny came to a screeching halt.

“Oooooh, hey Zane” she said.

She then gave a quick glance around and asked.

“Where’s Jamie?”

Considering you could hear the shower running through most of the house, it was pretty obvious where Jamie was. I looked at Jenny, nodded my head towards the bathroom and said.

“Guess”

“By herself?” Jenny asked. “Why ain't you in there with her? Our parents aren’t home?”

I answered sarcastically “No, but her little sister is”

Jenny shot me a sad look and responded.

“Awwwww did I interrupt your nookie time”

Keeping my same expression, I answered “Yeah, you did. Don’t you have someplace else you need to be?”

She just laughed at me and said “Nope. Nothing else to do all day. I’m gonna hang by the pool”

To which I responded very blandly. “Oh great”

Neither Jamie nor I had any plans to hang by the pool that day anyway, we both had plans for the afternoon. So, I really didn’t care about her plan to hang by the pool all day. I just had to respond that way to let her know that her presence was still a major inconvenience.

Again, Jenny just laughed at me. I couldn’t get rid of her though. She flopped down in the chair opposite me and continued to flirt and make small talk while Jamie was in the shower. Every other sentence was something highly suggestive or sexual. If I’d read her the way I would Jamie, I’d say the girl was horny as hell. The fact that she was staring at my crotch for the entire conversation was also a dead giveaway.

Since she couldn’t tear her eyes away from my shorts, I figured what the hell, let’s have some fun. So, I started shifting around, opening and closing my legs. Watching her eyes bulge out when she thought she might get a glimpse of something, and to be honest I really didn’t care if she did. It was a lot like watching my friends trying to get a peek down some girl’s shirt at school. Obvious, and hilarious.

The only problem was, now it was starting to turn me on teasing her like that, and it was starting to have an effect. So, Jenny might just get that show after all.

Then, almost exactly on cue, I was saved by the bell. Jamie came out of the shower all wrapped in towels and dripping wet. She took one look at Jenny sitting there across from me and said the same thing I’d said earlier.

“Don’t you have somewhere to be?”

If looks could kill they would have turned each other to ash.

Jamie looked at me and said.

“Shower’s free if you want to use it. I’m gonna go get dressed…”

Then she turned to Jenny and said.

“You can just go”

Jenny made the obligatory face at her sister and then stomped off to her room. Jamie and I retreated to her room. After a few hugs and kisses, and me trying to get the fires ignited again, Jamie yelled at me.

“Stop! Go take a shower already!”

Then she handed me one of her big bath towels and pushed me out the door.



Shower time - Zane

I turned the water on, adjusted the temperature, and jumped into the shower. Naturally, all wet and soapy, I started thinking about Jamie and wishing she were there with me to lather me up good. But occasionally, an image or two of Jenny would sneak into my little fantasy. I had to admit, she did have some pretty nice curves.

A moment later, as I was taking those thoughts of Jamie in hand, I happened to catch the bathroom door opening. I hid as best I could and slid the shower door open a crack to see who it was and found Jamie standing in the doorway. She smiled, and then told me that she had to run over to her friend Melissa’s house to pick up some of her sports gear. I was welcome to finish up and let myself out when I was done. If I wanted to stay and wait for her to return, I could, but she wasn’t sure how long she would be gone.

She blew me a kiss and slipped back out, closing the door behind her. I returned to the business in hand.

Not a minute later I had my eyes closed and my hand happily resuming its previous action with a sweet memory of Jamie in the shower with me. In between my own little moans, I suddenly heard another quiet little noise in that I didn’t expect. Through the fogged glass of the shower door, I spied a little blonde shape in the bathroom doorway again and figured Jamie had changed her mind and come back for some fun after all.

Again, I slid the shower door open and started to say.

“Decided you just couldn’t resist eh? …”

Then I realized, it wasn’t Jamie.

“Jenny!? What the fuck!? Get out of here!”

Clearly, I was caught by surprise and wasn’t thinking.

Jenny hesitated, then spoke up.

“Jamie wanted me to tell you that she had to go over to Melissa’s house…”

I already knew that.

“And you figured the best thing was to come tell me while I’m in the shower?”

Jenny cocked her head, shrugged her shoulders and gave a little smirk that implied, yeah, I thought it was a great idea!

I continued. “Oh, well why stop there, why don’t you just hop on in and join me?”

Her eyes widened and her smile grew.

“Really?” she asked.

“NO! Get the fuck out of here!” I answered.

Again, I was clearly not thinking.

Jenny scrunched up her face at me, then grabbed the big bath towel I had waiting and bounced out of the bathroom.

I stood in the shower for a moment seething about Jenny having the nerve to bust in on me in the shower, eyeballing me naked (and hard), stealing my towel, I should have just … Then it hit me. Wait, when I told her to just hop in the shower with me, she was all for it. I stood there shocked for a moment as images of Jenny in tiny little bikinis started to fill my head, and my cock began to really rise. Little sister wants to play!

Damn, I was stupid. I could be banging Jenny in the shower right now If I stopped for three seconds to think. How could my penis fail me like that? You were supposed to take over the thinking for me at times like that! How could I get her back in here? She did take my towel. I shut the water off. Looked around the bathroom and found a smaller towel which I used to dry myself off a little. Then I wrapped it around my waist and stepped out of the bathroom.

Jamie’s room was to the right coming out of the shower. Knowing that she wasn’t home, I held that little towel over my crotch and marched right across to the other side of the den to Jenny’s door. I banged on it once hard, then grabbed the handle and burst right in, dripping wet and barely covered. Jenny stood by her desk, eyes wide, staring at me and about to start protesting me barging into her room.

“Gimme back my towel” I barked at her.

She just stood there staring and pointed to the towel lying on her bed. I moved closer into the room, closing the door behind me, and grabbed the towel. Now I was only a few feet away from her. I looked at her as if I was angry but was happy to see where her eyes were locked. I dropped the little towel I was holding and let my hard cock fly out in front of me as I grabbed unfolded the bigger one then wrapped it around myself. A quick glimpse only, but her eyes almost popped out of her head.

Now that I was covered up again, I stood in front of her, crossed my arms over my chest, looked at her and said.

“Okay, strip.”

Jenny looked at me totally baffled.

“What?” she asked.

“Strip.” I said. “Take your clothes off. You got to see me, it’s only fair that I get a good look at you now. So, strip”

“But I didn’t…” she started.

“How long were you standing in the bathroom watching me in the shower?” I interrupted.

“You can’t see anything through those shower doors, you know that.” she said.

“What about just now?” I asked.

“I didn’t see anything I swear!” she protested.

I looked at her for a moment with an evil grin, the plan in my head already working. I reached down and undid the towel around my waist, letting it drop to the floor. My cock was hard as stone and popped right out to greet her.

Jenny let out a little gasp as she finally got a good look at what she’d been grabbing at all summer. I didn’t give her any time to think and said.

“Alright, now you’ve seen it. So, strip”

“I… I… I… I…” she stammered.

Then I took control.

“Five minutes ago, you were ready to jump in the shower with me. Were you going to do that with your clothes on?”

“No, I…” she began.

“Strip.” I said as I advanced on her again.

I moved up close to her and grabbed her shirt by the bottom and began to pull it up. Between my hands pulling at her clothes and my cock all but pressed up against her, her brain, her hormones, and her emotions were having a hard time keeping up with each other. As I was pulling her shirt over her head, leaving her in just her little white bra, she said.

“I wasn’t gonna…”

I moved closer to her still. My cock now pressing against her tummy. She looked down at it.

“Yes, you were” I answered. “What did you think would happen if you jumped in the shower with me?”

“ummmm… I….”

I leaned forward and put my mouth on hers. She immediately surrendered, closed her eyes and started kissing back.

“Oh my god.” she exclaimed.

I reached my hands up to her shoulders and pulled the bra straps down. Then I reached around to undo the back let her gorgeous breasts fall free. She offered no resistance at all. She was much bigger than I thought. Almost as big as Jamie. My hands began to tweak, and feel, and massage, and adore her perfect tits.

After a few minutes, I stopped and said to her.

“You know, considering how many time’s you’ve tried to grab my cock this summer, you seem to be completely ignoring it now that it’s practically stabbing you in the stomach.”

With that, I took one of her hands and wrapped it around my cock.

I could feel her shaking, and almost hear her heart beating, as she wrapped her hand around my cock, completely naked and fully engorged this time. She had gotten little grabs in before in the pool and such, but never anything like this. I could feel her shaking, she was so excited. I let her feel and explore for a few moments before I stepped away from her and said.

“Okay, now the rest”

She looked at me and asked “What?”

I pointed to her little red shorts.

“Those.” I said.

“You want me to…?” she asked.

“Of course” I answered. “We can’t do this if you have all your clothes on. Besides, you owe me. Now take ‘em off”

“Do what?” she started.

Again, I reached out, grabbed on to her shorts and started to pull them down. They slid down her legs easily and she stepped out of them, again offering no resistance at all. I reached up and grabbed her panties and started to pull those down too. She hesitated for the tiniest of moments, but then let them fall and stepped out of those as well.

What a beautiful sight she was. Bright blue eyes, her tits firm, her nipples hard, and her pussy covered with the slightest whisps of golden hair. I pulled her close and kissed her again. This time with my hard cock pressed against her belly. Her hands found it all on her own this time.

I sat her on the bed and stood in front of her. I took her hands, wrapped them around my cock, and helped her learn how to really pay attention to it. She was a natural. She just sat there saying “Oh my god” and “I can’t believe this” while I told her how to worship my hard-on. When I suggested she lean forward and put her mouth on it she gave me that look that said, really? I said.

“You have sucked a cock before, haven’t you? I see all those boys around you all the time, are you telling me you’ve never…”

“Of course I have” she spat back at me. Then she leaned forward and wrapped her mouth around my tool. Oh, she was amazing. Although it was clear that she had never done this before. Once again, I gave her some helpful tips and in no time, she was sucking me off like she’d been doing it for years. I couldn’t believe it.

All of this was nice, but I had no idea when or if Jamie was coming back. What I did know was that before she did, I was going to fuck her little sister. I hesitantly pulled Jenny’s mouth off my cock and laid her down on top of that big old towel on her bed. I lay next to her and wrapped an arm around her waist as I leaned over and started to kiss her again. Just like before, I could feel her heart pounding a mile a minute. My hand reached up and fondled her tits again for a short time, then I moved them down between her legs.

Jenny let out a short gasp the first time my fingers touched her lips. I rubbed her pussy, slowly letting my fingers slip inside her. Every new inch brought another gasp. She was breathing in a series of long, slow, deep breaths now. Every time she let out a breath, she would whimper a long soft moan. Then I sank a finger all the way up inside her. She cried out, tried to pull back a little, and held her breath again. I didn’t relent. I held my hand tight to her pussy and pushed that finger deep inside her. At the same time rubbing my thumb across her clit.

Jenny let out a little scream when I found her clit. She started moaning louder and louder and bucking her hands against my finger. I kept going, driving her almost to the edge. Then I backed off just a bit as I stood up off the bed. I spread her legs wide and pulled her to the very edge of the bed. I stepped up close between her legs, right in place to enter her.

Just as she was asking me what I was doing, I replaced the finger that had been massaging her lips, with the head of my cock. Sliding it up and down along her lips. Pulling her open just a bit with those fingers that had been inside her.

Jenny looked up at me and said.

“Wait, what are you …”

I kept pushing my cock against those lips and leaned down close. I whispered to her.

“Jenny, you knew this was going to happen if you jumped in the shower with me. This is what you wanted, isn’t it?”

“I didn’t think…” she tried to get out.

“Besides, what could you possibly do to piss Jamie off more than fucking her boyfriend?”

Her eyes went wide again. “You really want to fuck me?”

“OH yes. That is what you wanted isn’t it?” I asked.

She hesitated. “Well... yeah, but… I’ve never…”

“Never?” I asked.

“No.” she said, a little red-faced and embarrassed.

“Don’t worry.” I said, “You’ll be fine, I promise”

I leaned in and kissed her more, and started pressing my cock into her more and more until the head was inside her. I stopped kissing and stood up to get a better position. I gave a little back and forth to prepare her, then with a long slow moan of my own, I started to push into her.

Immediately I hit what had to be her hymen, or at least what was left of it. Jenny played a lot of sports so had likely burst it long ago. But there was still some resistance, so perhaps she hadn’t broken it all the way. With one hard push, I busted through what was left and drove a couple of inches into her. Jenny let out a little yell.

I left it inside her for a moment without moving as she caught her breath. Then I started to move back and forth, in and out of her. Her moans began to match the rhythm. With each stroke, I tried to get a little deeper. Most of the time she was only making little noises, but every now and then those would turn into “oh my god”, and then I would pick up the pace a little more.

I began to pump into her now, really pumping into her. A little grunt would escape from her every time I thrust. Jenny had two fists full of bed sheet as she did what she could to thrust right back. I pulled her legs up, lifting her hips just that much off the bed, and really drove into her. I was able to drive fully into her now, she was taking it all. I was ready to burst.

Without even thinking. I drove as deep as I could into Jenny’s incredible, tight little hole, and just let go. Everything I had, I pumped into her. I had been dating Jamie for six months, and fucking her on a regular basis for five of those months. Jamie was on birth control. I never even considered pulling out anymore. We just never thought about it, and so, I didn’t think about it now either. When the moment came with Jenny, I just let loose and filled her up. It felt just as amazing as it did with Jamie.

I stopped while still inside her. I was spent. She too was spent. She just lay there saying “Oh my god” to herself over and over. I pulled out and lay next to her for a moment. I had no idea how long we lay there. It wasn’t until my I heard my phone ringing over in Jamie’s room that I realized how much time had passed. I bolted upright and ran to Jamie’s room to grab the phone.

It was Jamie, but luckily just a text. She said she was going out with Melissa for the night and would see me the next day. That was a relief. I walked back across the hall to Jenny’s room, ready to stiffen up and do her again. There she was still laying on her bed in the same place I left her, but now with her hand between her legs rubbing her pussy and playing with the cum oozing out of her. That was when I froze.

“Jenny,” I said. “I don’t suppose you’re on birth control, are you?”

“What?” she asked. “No, why?”

Oh shit.

“I came inside you.” I said.

She didn’t catch on right away. She was still registering that she had just been fucked and wasn’t a virgin anymore. Once she did realize what I’d said, she ran for the shower thinking she could wash it all out of her. I let her do her best while I got dressed then told her to get out of there and get dressed as well. We made the quickest trip ever to a pharmacy the next town over and picked up the morning-after pill. That is, I bought it. She waited in the car. At that point, all we could do was have her take that pill, and pray for the next month, or however long it took.

Both of us were all nerves whenever I would be at their house, and conversations between us were very awkward. Not the fun flirtatious little exchanges that we’d always had before. Even Jamie noticed and remarked about it once. I assured her I had no idea what Jenny’s problem was.

Finally, the day came. When Jamie and I got home after our morning run, the huge smile and happy greeting from Jenny told me all I needed to know. Her period had arrived and we were safe. That had been entirely too nerve-wracking.

The rest of the day was fun. Jenny was back to her old flirty self. Throwing the innuendo around like a drunken sorority girl. She even actually stuck her hand down my shorts whenever she thought she could get away with it. Her friends were all gathered around her all day giggling and squealing and laughing just like before. After a few hours of this, Jamie remarked.

“If I didn’t know better, I’d say she got laid”

Oh baby, if you only knew.

Jenny and I had a little talk at some point during the day and I told her I’d love a repeat performance sometime, but she had to get on the pill. She could also never tell Jamie. She could sit back and laugh every time Jamie started giving her shit, but she couldn’t say anything.

After that day, anytime Jamie went off on her sister, I could see the grin on Jenny’s face as she sat there listening and thinking.

“I fucked your boyfriend, I fucked your boyfriend…”
