THE INTIMACY EQUATION

A brother and sister confront the Sibling Paradox

Ron Ehrs

I got up early on Thursday morning. My last exam had been Wednesday afternoon, and I finished packing my stuff that night. I headed over to the student center for breakfast. I wondered if Cassie might happen to be there, but there was no sign of her. A lot of the students were already gone, although I knew she wouldn't be leaving until Friday.

I went and got my car from the lot and parked as near my dorm as I could to carry out my stuff. It was going to be a long drive, and I wanted to hit the road.

I was headed for Lakewood, a small touristy town on the banks of Lake Quinn. My father had rented a house there for the summer. I think he was beginning to realize this might be his last opportunity to have us hang out together as a family for a summer vacation.

None of us had ever been to Lake Quinn before, but it was a well-known vacation area, and my father liked the idea that he could get in some sailing, his favorite hobby.

It sounded like a nice break for all of us. I had spent last summer as an intern at Dad's law firm but given that I was going to start law school in the fall, and I heard how much studying law students had to do, I was more than ready to take the summer off.

It was a long drive, about four and a half hours not including a break for gas and lunch. Fortunately, most of it was on the interstate and traffic wasn't too bad. Once I started getting closer, I had to head off to state and then local roads. I was glad that my GPS worked out here.

The last stretch was on a road that went along Lake Quinn, I got to see the lake as I drove. It was a beautiful day, and lots of people were out in sailboats. It was definitely a great place for a summer vacation.

* * *

It was going to be a while before I got to Lakewood. As I drove along, admiring the scenery, I began thinking about the summer ahead.

In particular, I began thinking and wondering about Cassie.

I had just graduated from State, majoring in economics and finance. I would start law school there in the fall.

Cassie was a year younger and finishing her junior year at State. She was majoring in history and politics -- I had no idea what she expected to do with that.

Even though we had been on the same campus together for three years, we hardly ever saw each other. I mean, it's a big school -- maybe 50,000 students, including the law school and the business school and grad students -- but it's not huge. Yet we would only end up running into each other a couple of times a year. And even though I was in a frat and she was in a sorority, we never ended up at any parties together.

Still, we did run into each other every couple of months. Maybe it was the amount of time between these meetings that made things a little weird. It seemed like every time I ran into her on campus I was running into a different person, someone I knew that I knew, and yet almost an apparition from another dimension. Her freshman year, she was a just a freshman, all excited about college courses. Now, that had all changed, and I would find myself standing in front of one of the hottest girls on campus.

When I ran into her two months ago, she was wearing a miniskirt and one of those shirts that left her stomach bare. While she was talking to me, I would feel my jaw dropping and my mind losing any hope of concentration.

And when she left, I would find myself watching her ass moving in that miniskirt. I don't mean that way. I mean she was my sister. It was more like just... observing. Right?

Thinking back, it seemed like that was about the time the girl I had been dating and I broke up. And for some reason, I hadn't bothered looking for anyone else to go out with since then. Maybe it was too close to exams.

My Dad was a lawyer, kind of a big deal, a name partner at the biggest law firm in the city. He did a lot of complicated stuff connected with major business deals, mergers and acquisitions, all that kind of thing. My Mom worked at a local PR firm, not as big a deal, but she enjoyed her work.

Anyhow, Dad's firm was holding a kind of vacation/retreat in the Napa Valley this next week, and obviously my mom wanted to go with him, so it would just be me and Cassie on our own for the first week.

I mean, Cassie and I would see each other at home on Thanksgiving and Christmas break, and maybe some other vacations, but then we were always just the kids in the family. It was never just the two of us. In a way, this was going to be the first time the two of us were together as "adults."

I had no idea what that would be like.

* * *

Eventually I arrived at Lakewood. The road I was on went straight through town, so I had a chance to get a look at it. It wasn't all that big, but it wasn't all that small either. Loads of shops, restaurants, souvenir stores, and a big section of docks where sailboats, fishing boats, tourist ferries and the like would come in. Pretty much what you would expect for a summer town. I was glad there seemed to be enough there to keep us from going completely stir-crazy.

The house Dad had rented for us was a couple of miles north of town, on a road running right along the lake.

When I found the place, it was one of many A-frames along the road and in the area generally. It was smaller than a lot of the others -- not really small, but some of the others had been built with five or six bedrooms to be rented by groups of people or extended families. This house had been built by the owners for their own family, the parents and two kids. It wasn't small, but it only had three bedrooms: a master bedroom downstairs and two bedrooms and a bathroom upstairs. There was also a separate two-car garage off to the side.

The kitchen faced the driveway, but it wasn't closed in, so it had a view of the lake through the floor-to-ceiling windows in the living room.

On the kitchen counter, there was an envelope that Dad had mailed to me and Cassie and had been brought in. I opened it and there was a substantial bundle of cash with a note from Dad telling us to use it for whatever we wanted.

There was a master bedroom on the left-hand side, and down from it, with a view of the lake, was an area with a desk. I figured that would give Mom and Dad a place to hook up their laptops and connect with their offices while they were here.

I went upstairs and put my suitcase on the dresser in one of the bedrooms. It was a decent size bedroom with a floor-to-ceiling window looking out over the lake and had a double bed. I guess the owners wanted to make it usable for larger groups than just two parents and two kids.

I changed into shorts and a T-shirt and put on some flops and went downstairs. Mom had texted me that they had hired someone to stock the kitchen in the fridge, and Dad had made sure to order wine and beer and other drinks to be ready for our arrival.

I checked the fridge and made a sandwich. Then I grabbed a beer and took it in the sandwich out to the back deck to relax. It was gorgeous out there. The sun was just setting and everything looked like a perfect picture postcard.

As I looked around, I noticed something on the right-hand side with a cover on it. I went over and lifted the cover, and sure enough, it was a hot tub. I put my hand in the water; it was lukewarm at best. I looked over and found the switch and turned it on to start the heater.

I sat back down and finished the sandwich and the beer and went back in and got myself a second beer. I sat back down on deck, and when I was almost finished with that beer, I decided to check the water temperature in the hot tub. It had heated up nicely.

There was a cupboard with some towels there. I took off my clothes and got into the hot tub. It felt great, especially after that long drive, and sitting there at the looking out at the lake was a perfect start to the vacation.

* * *

The next morning, I slept late. It was nice not having anything to do and having all my classes and exams over with.

After breakfast, I decided to go out for a jog along the road to the house. There wasn't much traffic so it seemed pretty safe.

I returned after about an hour. I went upstairs and showered and came back down. But now I had pretty much exhausted my to-do list. I had brought along a few paperbacks, but I wasn't in the mood for reading. There was a TV, but I wasn't in the mood for that either. All I could do was wait for Cassie's arrival.

* * *

It was late afternoon when I heard a car pulling into the driveway. I went to the kitchen and looked out and I saw Cassie's convertible. Dad had gotten me an SUV when I got my driver's license. It was very practical and had lots of space. Cassie persuaded Dad to get her a flip-top convertible. A lot less practical, but more fun.

I saw Cassie walking up to the door and opened it to greet her. She gave me a big hug. "Chip, you're looking great! How is this place?"

"It's really neat," I said. "Pretty much perfect for us."

I went back out to her car with her to get her suitcase while she carried a few extra things. We went upstairs, and I showed her the other bedroom. "This is awesome, I can't believe the view."

I went back downstairs to give her a chance to do some unpacking and get changed.

When she came back downstairs, I said, "There's a pizza place down the road called Benny's. I haven't been there, but it looks like it might be okay. I thought it would be someplace convenient to go for dinner."

I thought she might want to drive us there so I could enjoy the convertible, but she was tired of driving, so we hopped in the SUV.

* * *

Benny's turned out to be very popular. We were lucky to get one of the remaining tables, but fortunately, it was one of the outside tables with a nice view of the lake and the sailboats going by.

We ordered beer and pizza and relaxed watching the boats on the lake until our order arrived.

When the pizza arrived, we both dug in. "This is really good pizza," I said. "I suspect we may become regulars here. I'm pretty sure Mom and Dad will like it too."

After the second slice, our eating pace slowed down. Cassie paused as if she had something on her mind.

"You know, Chip, I was thinking about something on the drive up here. It's a pretty long drive so lots of time for thinking. Anyhow, I was sort of wondering... I mean we've been on the same campus for three years now, and we hardly ever see each other. Like, you send me a text or an email once in a while, but we've never gotten together for lunch or for dinner. We run into each other once every couple of months maybe, and it's great seeing you, and it's really nice getting a chance to talk, and we always say we should get together soon. But it never happens. The only time I really see you is when we're home for holidays or vacations or something.

"I know it's a really big school, but it's not that big. If it was a town, would be kind of a smallish town. Maybe one step up from a small town. And if we lived in a town that size, we would probably see each other more often than we do.

"I party a lot, I'm sure you do too, but I don't think we've ever been at the same party at the same time. So, I was just wondering. Is there some reason for that? Have you been avoiding me? Have I done something wrong? I mean I've really been looking forward to hanging out with you this summer, so I'd like to know what's up."

I hadn't been expecting this. Even though I knew exactly what she was talking about.

"I haven't been avoiding you, Cassie. I suspect a lot of it is that we have such different majors and such different courses. Our classes are usually taught in buildings in very different parts of the campus. And your sorority is on the other side of the campus from my fraternity. I mean maybe in a way it's surprising we run into each other as often as we do. I always love seeing you and talking to you, and I'm really sorry that we haven't ever just gotten together just the two of us. I don't know why, except that we're both really busy with courses and other stuff.

"As for parties, I don't know. I mean I guess I mainly go to parties at my own frat. And I'm not quite sure how I would feel about seeing you at one of my frat parties, you know, seeing some of my frat brothers checking you out and trying to hit on you. I mean I know they're my frat brothers and all, but I don't think they're all necessarily fine upstanding gentleman like me. I'm not sure I would trust them at all."

"Or maybe you wouldn't trust me?" Cassie said.

"Of course I trust you," I said. "But I definitely don't trust them. I know them too well."

Cassie laughed.

* * *

When we got back to the house, we went upstairs and changed into gym shorts and T-shirts.

While I was waiting for Cassie to get back down, I surveyed the liquor stock. I saw a couple of half-size bottles of premixed margaritas from some brand I had never heard of before. A lot of times, that kind of margarita is pretty watered-down, but I checked the proof and it was pretty much like the proof on a decent margarita at a bar.

I found a couple of margarita glasses and got out some ice cubes and poured us a pair of margaritas. When Cassie joined me again, I suggested that we sit on the deck and enjoy the evening air.

We headed out and sat down in some chairs facing the lake. We clicked our glasses and toasted: "Here's to the summer ahead."

The margaritas were pretty strong, and I started feeling mellow pretty quickly. Cassie was looking out at the lake, and then I saw her look over to the right where the hot tub was. I had put the cover back on, but it wasn't exactly hidden.

"Is that a hot tub," she asked. "Does it work?"

"Yeah," I said, "I turned it on last night and hopped in to relax from the drive. The thermostat is still on."

"That sounds perfect," Cassie said. "My muscles are sore as hell from all that driving."

Without saying anything more, she got up and went over and pulled the cover off the hot tub. "Wow, I can already feel the steam. I can't believe we have this here. This is awesome."

I was watching her, not really thinking too much about the situation.

Suddenly I saw her pull her T-shirt over her head, and then quickly pull off her shorts. She wasn't wearing any underwear.

Oh my God. I couldn't believe what I was seeing. I couldn't believe this was happening.

And the thing is, her naked body was even more amazing than I could've imagined. She was absolutely gorgeous. What the hell was I supposed to do? Pretend I hadn't noticed? We both sure as hell knew that wasn't true.

By now she was sitting in the hot tub. "Chip, this feels fantastic! Get over here and join me."

What? Did she want me to get naked with her? Where did all of this come from? In what universe was this supposed to be a good idea?

"Come on, Chip! Move it! Or are you some kind of fuddy-duddy?"

Was I a fuddy-duddy? It kind of felt like it, but Cassie was pretty much ordering me to join her.

I wasn't even sure whether to pull off my clothes where I was or walk over and strip right in front of her. What were the rules for this kind of thing anyway?

* * *

I stood up and pulled off my T-shirt and shorts. I wasn't wearing underwear either. I walked over to the hot tub, feeling definitely embarrassed about being completely naked in front of my sister. I mean she seemed fine with getting naked in front of me, but I was just feeling confused.

Cassie was watching me the whole time. I couldn't tell whether she was checking me out now that I was naked, or simply waiting for me to get there. She was definitely smiling.

I climbed into the hot tub and sat down on the bench where she was sitting. It had felt really comfortable last night, but this was completely different.

Almost immediately, Cassie moved over next to me. I could feel her naked body rubbing up against me. I was surprised, but I didn't want to say anything. I mean, suppose she realized what she was doing and moved away? She'd only end up feeling embarrassed, and I would feel bad about having embarrassed her. Not a good start to the vacation. Besides, was there anything really wrong with that anyway?

We were looking out at the lake, and the light of the moon was reflecting off the surface of the water. It was a picture-perfect scene.

Then I felt something. It was Cassie's hand, and it was wrapped around my dick. She wasn't looking at me or saying anything, it seemed like she was just waiting to see if I was going to say anything or try to remove her hand. I hadn't been expecting this, but did I really want to put a stop to it?

Just sitting there naked beside her and feeling her body against mine I had already had a hard-on, and now with Cassie's hand, I felt myself getting even harder.

By now I was enjoying this, but then Cassie said, "I shouldn't be doing this, should I? You know, brother and sister? Do you want me to stop? On the other hand, we are on vacation."

"It feels great," I said, not quite sure if that was an okay answer, "don't stop on my account."

She began moving my cock in her hand back-and-forth and sideways like it was a stick shift in a racing car. "Vroom," she giggled. "This is fun. Do you like it?"

"I love it, "I said, "as long as I can feel your tits at the same time."

She giggled again. "That sounds naughty," she said, "but it also sounds hot. Go ahead."

I reached over and began feeling her breasts. She had awesome breasts, big and full and firm. They were perfect hemispheres, no drooping, no sagging, I began feeling one and then the other, and then the first one again. As I kept feeling her breasts, I felt her nipples begin to get hard and stick out as if calling for attention.

I began to play with her nipples, and she kept on shifting my cock back-and-forth, going "Vroom, vroom."

Gradually, I felt her hand began to move up and down on my cock as well as shifting it around.

It had been some time since I had gotten laid, so I was pretty horny. I had already known that Cassie was hot, but now that she was completely naked, she was even hotter.

Gradually, she stopped shifting my cock around and was just running her hand up and down it. Both of us were breathing much more slowly, and I was wondering what to do next.

* * *

There was a double recliner to one side of the pool. I think we both spotted it at the same time, and had the same idea.

We both stood up without saying anything. We got out of the hot tub, and headed wordlessly over to the recliner. Cassie lay down on the recliner and opened her legs. I positioned myself above her, between her legs.

I took my cock in my hand and rubbed it up and down between the lips of her pussy. She was already wide open for me, and I began pushing my cock into her.

"Oh my God, I can't believe my sexy hot brother is sticking his dick inside me!" she was saying. "This is so weird! Do you like fucking your sister?"

I didn't bother answering, I was too busy leaning forward to suck on her tits and her nipples.

"Oh Chip, that's so hot! I love you sucking on my nipples. And I love having your cock all the way inside me. I can't believe my own brother is actually fucking me! Fuck me as hard as you can! I want to feel my brother's dick shooting inside me and filling me up! I want it all! Fuck me, fuck your horny sister, fuck me!"

Her hips were thrusting up against me, and she was grinding against me as hard as she could. "I'm coming! I'm coming for you! I'm coming for my sexy brother with the big dick!"

By now, I couldn't hold out any longer, and I began pounding into her as fast and hard as I could. Her pussy was wrapped tight around me trying to hold on to me as my cock moved in and out. I couldn't believe how hot this was.
