When I woke up, it was pitch black. Not even like last night; I couldn't see my hand in front of my face.

The fact that the room smelled like sex and I was definitely not in my bed gave away that last night had not been a dream. I definitely didn't want it to be, anyway.

I felt around the bed in search for Katie, and finally found her. I put my hands on her shoulders and slowly dragged them down her arms. She let out a quiet, but long sigh of pleasure just from my touch, and interlaced her fingers with mine once I'd reached the end of her arms. She snuggled back into my arms, which I wrapped around her so that hers were crossed, and she rolled her neck so her head rubbed against my shoulder.

I craned my neck and pulled on Katie's waist so that her neck lined up with my mouth, and kissed it lightly several times. I slowly worked my way down, as far as I could from behind her, and with each kiss her breath became shorter but louder.

"Mmm, Jack..."

I touched my nose to her neck lightly, and dragged the tip of it up to her ear. Then I moved my hands up to her breasts, squeezing them tightly. Katie had either already taken off her bra this morning, or hadn't put it on since last night, so her breasts were completely bare. Katie moaned, then gasped, then let out a little laugh. She pulled my hands away.

"Oh come on, Jack. You'll have plenty of time for that later."

That damn voice!

Katie suddenly swung herself on top of me, and kissed me hard on the mouth, keeping her lips together this time. She began to grind against me, pressing her breasts against my bare chest as well. I could barely stand this - I was either going to pretty much cum in my pants or tear off what little clothing she was wearing.

Suddenly, she got up and slipped out of bed. She threw a shirt on and walked out the door, then took a left for the shower.

I half groaned and half laughed, burying my face in her pillow. 'Grr, that bitch is such a tease!'

I inhaled sharply, and got a nose-full of the sweet smell of her hair. I hadn't really noticed how good Katie smelled, and this new discovery turned me on even more. I rolled onto my back and groaned, trying to allow my eyes to adjust to the endless darkness, but with no success.

A dim light broke my concentration and eliminated the need, allowing me to at least see the source. The light was quickly accompanied by some buzzing, then a text tone. The commotion was my phone, letting me know I had a message. Since I didn't want to leave the bed, I reached down and hooked my pants pocket with my finger, bringing my pants to me so I could get my phone. I fished around in the wrong pocket for a second, then found it in the other, and opened it.

"Aren't you going to join me?"

It was from Katie, obviously, and she wanted me to join her in the shower. A little grin crept onto my face, and I stood up and left the room, naked.

When I got to the bathroom, the lights were, of course, off. This came as no surprise, except that I hadn't known her to shower with them off. The water was running, but the fan was off, so I stepped into the shower.

As soon as I had, Katie's hands were on my already hard dick. She began stroking it lightly, very lightly, which was driving me crazy. I reached out for those amazing breasts, but her hands came off my dick and redirected my hands to her ass. I gave it a hard squeeze, which made her squeal, but she jumped up and wrapped her legs around my waist, kissing me again.

Afraid she was going to slip off of me, I turned her around and balanced her against the wall, which made her moan and gasp again, as she wrapped her arms around my neck and kissed me over and over.

I kept squeezing her ass, which we were both really enjoying, as one hand stroked my chest and belly, down to my cock, which she slowly guided into her.

I began pumping back and forth, gaining speed, but she whispered into my ear.

"No, don't fuck me. Love me. Make love to me, Jack..."

That voice could have made me jump into the ravine. I slowed down immediately, and began to kiss her neck again, as passionately as I could. I kept squeezing her ass, slower now than before, and she pushed her tits tight together and squished them against me.

I relied on my dick and the wall to hold her up, as I pulled my hands away and grabbed her breasts firmly. I rubbed gently, trying to stay passionate and not want to ravage her entire body.

As the hot water fell down my back, I remembered the light.

"Why no lights or fan? It's going to get twice as steamy in here."

"Power's out."

That was all she said, since she was cut off from anything else by her own scream as I pushed back into her.

"Oh my God, screw making love! Fuck me, Jack!"

This was the first time in over 24 hours she'd said something to me without using that voice, but I wasn't going to ignore thatcommand. I moved my hands back to her ass, working it like dough, and buried my face in those breasts. While kissing and licking her breasts, and kneading her ass, I pumped in and out of her furiously, causing her to moan and scream and curse, as she violently threw her head back and tightened her grip with her legs. Through her screams, I could barely make out the words she was saying.

"Oh my- ooh- God! Jack, I'm- aahh, fuck! I'm going to cum!"

She orgasmed intensely. Just from how tight and hot her pussy got, I could tell it was a big one. Katie's entire body shook, but I was far from done.

As she screamed with pleasure, I kept thrusting into her, faster and faster, and gave her ass a huge, strong, tight squeeze. She suddenly started swearing under her breath, through her teeth, and I could almost see her eyes, they were so filled and gleaming with lust.

Her hands came loose from my neck as she experienced a second orgasm, followed quickly by a third. But for whatever reason, I just wasn't feeling it. I felt like I could fuck her forever, and she didn't seem to mind. She was so hypnotized by ecstasy that she couldn't even tell me to slow down.

I didn't want to slow down, anyway. I wasn't even getting tired, only felt like I was getting stronger and could go faster. As my bloodstream filled with adrenaline, I even felt like my dick was increasing in size, and so did she. Her screams got so loud they hurt my ears, and I was afraid she'd tear her larynx, if the neighbors didn't break down the door first.

Her arms were now against the wall, and I slapped her ass once before pinning them there. The water going down my back seemed to be getting hotter, and the sex with Katie definitely was.

It was so steamy I was dripping from my hair, even though it'd never run under the water.

Katie tried to do her sexy voice, but was consistently interrupted by herself.

"oh oh! yeah, Jack, just aahh!!! Fuck me! Harder, Jack, faster!"

Her back arched as she had her seventh or maybe eighth orgasm. I wasn't even counting anymore; I was just waiting to cum, even though I really didn't want to.

Finally Katie found the strength to move my hands to her breasts, and had me rub them in circles. That was what finally sent me over the edge. I came, at last, but this was no spot in my pants. I came hard, and long. The orgasm lasted for almost thirty seconds, and I felt the cum drip back out of her pussy and down my shaft as I began to slow my thrusts down.

Katie simply slipped off of my cock and kissed me hard. With that, the lights somehow came back on. I still wasn't the least bit tired after that fuck, but she was obviously exhausted.

"Oh my God, Jack, that was amazing! I've never felt so many orgasms, not even while fingering myself. How did you go so fucking long?"

"I have no idea. I'm not feeling anything here; that was great but I'm still full of energy."

"Oh? Well too bad you made my pussy hurt, or we could solve that."

I smiled, and she turned around and pressed her back to my chest, placing my hands on her breasts again.

"Are you on the pill?"

"Of course! I'm not stupid enough to let my own brother get me pregnant. Why are you only wondering that now, after fucking me three times?"

I laughed.

"I guess I don't know. It was just too good to wait any second longer for. But you're such a tease; I have to wait forever anyway!"

"Oh come on, I can't stand to wait for you for too long. If I'm horny enough, I can hardly tease you at all."

I rolled her nipples in my fingers, and she gasped a little.

"So, I know I was a virgin before we... before this... happened. Were you, too?"

"Yeah. You know I've never had a boyfriend, don't you?"

"Well, you're a beautiful girl, there are the odds of... you know, one night stands, or-"

"Are you calling me a slut?"

She didn't exclaim this last part, but instead slipped into her seductive voice, which made me weak in the knees.

We washed up, silently, and toweled off, then went about the day as normal. Katie kept giving me signs that there was more to come, but nothing happened before Mom came home. Thinking she was back early, I checked the date. Katie and I had first fucked on Saturday night, so last night was Sunday. The note said Monday, which threw me off. It should have said "tomorrow". She must have written it late on Saturday. Maybe while she was still drunk.

It didn't matter. The fun was over, for now, but Jake and Grace were getting out of the car. I went out the front door to say hi, and immediately was hit by Jake. He wrapped his arms around my waist, and gave me a tight hug, which reminded me of Katie around my waist in the shower. I hugged back, lifting him clean off his feet, which made him giggle hysterically. 'Score,' I thought, 'he's still young enough to find that fun.' I took his bags to the downstairs bedroom, the first guest bedroom, and showed him where everything was. When I came back out, I saw Grace, next to Katie.

'Holy...'

Grace's breasts were, like I remembered, not as big as Katie's, but she was GORGEOUS! Her hair was light brown, but really long. It fell down to her ass, which was perfectly formed, and looked exactly right to squeeze. Her face was freckled, and she wasn't the small-eyed child I'd remembered. She was a total babe!

In comparison to Katie, she wasn't quite as hot, but she was prettier in her own way. Grace had always been taller than Katie, which put her at a perfect height to be fucked.

For whatever stupid reasons, I didn't find it weird that I was thinking about her like this. It struck me that it wasn't going to happen, but it would be nice to have her around, especially since she and Katie were close. Maybe Katie could talk her into something...

I didn't say anything to Katie immediately, but I knew I needed to ask. Grace came over and hugged me, and kissed me on the mouth. Not the cheek, the mouth. Just a peck, but it was enough to daze me for a second before I could stammer a "Welcome."

Once I had, I felt incredibly stupid and probably looked retarded, but shook it off. My mom left to buy some groceries, so it was just Jake, Grace, Katie and myself. We all sat down to watch t.v., but got bored and decided to play truth or dare instead. The closest grocer was on the other side of the ravine, up top of the canyon, so mom would be an hour out, an hour there, and another back. After some basic questions and dares, Jake went to bed. His bedtime was 9:00, which he simply enforced by himself.

About an hour had passed, but it was just the three of us now. We quit truth or dare, because Katie "didn't want to make [us] do anything stupid."

Instead, Katie ran to the kitchen, saying she had something fun. She came back with a bottle, to which I groaned, but Grace looked excited. Was she hiding something?

"Katie, this game is silly. We're all related."

"That's why it's more fun! It's funny for everyone else."

Finally, I agreed, both reluctant and excited to land on either of the girls. I reached for the bottle, but Katie handed it to Grace. Grace swept her hair away, which turned me on for some reason. She was just so hot, no matter what she did!

Grace spun the bottle first. Just my luck - it landed on Katie. Or was this just my luck? Now I was excited.

Grace leaned over towards Katie, and gave her a passionate kiss on the lips.

"Whoa, we're playing like that?" The "whoa" was part surprise and part lust as my dick sprang up. Good thing I was wearing jeans to cover up.

"Of course. Come on, Jack, it'll be fun!"

Katie took the bottle next, and spun it. The mouth pointed at me. I didn't have any problem with this, but in front of Grace?

Before I could stop anyone, Katie's tongue was quite obviously inside my mouth.

'Alright, if we're playing like that...'

I put my arms around Katie and swept her into a kiss of my own. She even moaned a little as I pulled away from her mouth.

Grace laughed, and then pushed the bottle to me.

"Your turn, Jack."

I reached down and put three fingers on the bottle, then flicked my wrist and sent it spinning...
