Wednesday

All day I was feeling like a kid on Christmas. My sister, my lover, the girl of my dreams, was coming to visit. I was counting down the hours to her arrival. She told me she’d be at the station at four, and that’s where I was now, waiting to pick her up. The train arrived exactly on time, and when the flood of people began to disperse, there she was. I waved for her, and as soon as she saw me, she came running. She leaped into my arms and covered my face with kisses while she whispered how much she had missed me.

I picked up her traveling bag and carried it for her while we walked hand in hand to my car. Like a real chauffeur, I opened the door for her and closed it when she sat. Then I tossed her luggage in the back and sat down behind the wheel.

“Where do you want to go, milady?” I asked, taking off an imaginary driver’s cap.

“You may drive me home, Charles.”

“Shall I take the scenic route?”

“No, you shall take the shortest,” she said sternly, but with a twinkle in her eye, before she burst out in laughter.

“As you wish, milady.”

I turned the key in the ignition and drove crosstown from the station to the university campus. I parked the car and led her to my home. As soon as we were alone, she was back in my arms and locked her legs tightly around my waist. I carried her into the home and kicked the door shut. While I was navigating the house, she was kissing me fiercely and unbuttoning my shirt. By the time we made it to my bedroom, my shirt was somewhere on the floor and she was fumbling with my belt. I threw her onto my bed and soon she was just as naked as me.

Half an hour later, she lay in my arms, her head on my chest. We were both sweaty and fatigued, but content.

“I want to take you out on a date,” I said.

“Like, a proper date?” she asked lazily.

“Yes. Boyfriend and girlfriend. A date.”

“They’ll see us.”

“I don’t care.”

“I have nothing to wear.”

“You’re beautiful, no matter what you wear.”

“A real date?”

“Yes. You and me, tonight.”

“I’d love to.”

I took Audrey out to a nice little restaurant not far from the campus. We sat at a small table in a dark corner. Audrey ordered the pan-fried halibut with seasonal vegetables, and I had venison tenderloin with a red wine sauce and a leek and potato puree. For dessert, we had crème brûlée and a shot of espresso. The food was delicious, and the company was even better. Audrey was looking absolutely beautiful. She was smiling and chatting as we ate the delicious meal, feeding each other bits of our own plate.

After dinner, we went to see a late movie. Her hand was on my leg the entire show, and we spent more time smooching than watching the picture. As the end credits rolled off the screen and the lights softly lit the room, we got up and followed the other patrons outside. It was dark, and the temperature was dropping fast. Part of me wanted to take Audrey home and cuddle some more before we went to bed, but more than that, I wanted to make this moment last. Tonight had been the best night I had ever had, and who knew when we would have an opportunity to repeat this? I’m sure she felt the same, and we strolled through the streets, hand in hand, taking the long way home.

Thursday

I woke up from an erotic dream. A suntanned Audrey and I were marooned on a deserted island, and we were making love on the beach. The coral sand was soft and warm, and the surf was washing around my feet. My lover had her legs wrapped around my waist, and I was about to erupt inside her when the alarm clock started beeping. I was confused when I opened my eyes, and the dream continued. The sunny beach changed into a sunlit bedroom, but the heavenly sensation remained. When I finally was awake enough to be able to discern between dream and reality, I realized where I was and what was happening.

As I flipped back the duvet, I was greeted by my sister, who had her lips around my morning erection.

“Hi, baby,” I said as she looked up in reaction to the sudden flash of daylight.

She stopped sucking and came crawling up. “Good morning, sleepy,” she replied, smiling, as she straddled my waist and took my swollen member all the way up her hairless pussy. Even though I probably should be exhausted from the intense and lengthy lovemaking that followed our romantic evening last night, I was fully reinvigorated, and so was she. By the time we finally got out of bed, I barely had enough time to shower before I had to go to college. Breakfast had to wait.

Twenty-six minutes later, I walked to the lecture hall. A playful punch to my shoulder woke me from my reverie.

“I didn’t know you had a girlfriend?” I heard someone say.

I looked behind me and saw one of my mates.

“I saw you yesterday, but you were too busy to notice me,” he said.

“I’m sorry, I-”

“It’s okay. If I had a date with a girl like that, I wouldn’t have noticed you either.”

“Thanks.”

“No, really, she’s hot! She doesn’t by chance have a sister?”

“I thought you were still seeing Ashley?”

“Yes, but I’m always ready to trade up.”

“Well, I’m sorry, mate. She’s only got a brother, and I think he’s already taken.”

“Too bad,” he laughed. “So, where did you meet?”

“I don’t know, I’ve known her practically all my life. It just ... you know, happened.”

“Well, congrats again.”

“Thanks.”

Thankfully, there wasn’t time for more interrogation, as we were late already. There wasn’t even time to get a sandwich, so I had to sit through three hours of lectures on an empty stomach. I made a mental note to program my alarm clock at least half an hour earlier if I wanted to have breakfast this week.

During lunch hour, more of my friends gathered around me, all demanding to know who the hot girl was that was visiting me. Apparently, Audrey had made quite an impression.

It wasn’t hard to hide the truth from my friends. I didn’t even have to lie or make up stories; Audrey really was my girlfriend, and none of them had any reason to suspect there was anything extraordinary about our relationship.

The conversation I had with my mates made me think. Nobody in town knew Audrey, or that she was in fact my sister. To them, she was nothing but my girlfriend. In two months, Audrey would have finished high school and go to college, like me. It just happened that my university was one of the institutions she was considering attending. How great would it be if we could really be living together, here, in a city where nobody knew our secret?

We could be lovers and no one would frown upon us. Better yet, for the price of two rooms, we could also rent a small condo. We’d be together day and night, and maybe, in a few more years, we could pretend to be husband and wife, and even raise some kids of our own.

My thoughts drifted off to a beautiful future, when I was alerted by sudden activity around me. The other students all started packing their books and notes. The lecture had ended and I hadn’t heard a single word the professor said. I wasn’t sorry; this was the last course of the day, and the end couldn’t have come soon enough. I quickly tossed my stuff in my bag and got up, paying no attention to my friends as I rushed off.

I practically ran all the way to my room. My sweetheart was lying on my bed and rolled over as she heard me come in. I leaned over her and greeted her with a kiss. She pulled me onto the bed and straddled me, kissing me passionately while she was dry-humping me. Clearly, I wasn’t the only one who had missed being together.

“Wow,” I could say after we finally broke up our kiss, gasping for air.

“I’ve been so lonely,” she said. “Six hours is just too long without you.”

“I know,” I replied and kissed her again, popping the buttons of her shirt at the same time. Twenty minutes later, I was lying in her arms in post-coital bliss.

“So, what have you been doing all day, besides being lonely?” I asked lazily.

“Shopping. I’ve got the perfect dress for our next date,” she said. “And I’ve been reading. Do you want to hear about when Mom introduced Dad?”

I was surprised she’d even brought the diary, but I should have known better. Audrey seemed eager to tell her story.

“Is that what made you this excited?”

She nodded. Nan had not remarried after Grandpa’s death, so I assumed there wouldn’t be too many steamy sex stories anymore. Apparently, I was wrong.

“Sure,” I said.

Audrey pushed me off of her and walked to the door, still naked and with creamy cum trickling down her leg. After a quick rummage, she pulled the book out of her traveling bag and got back in bed. She straddled my lap again and began to read.

“Donna introduced her new boyfriend today. His name is Michael, and they met two months ago. She’s really gotten to like him, and she says he could be the one. Of course, Donna has said that before, but this time it is different. I hope it’s true; he’s such a nice young man. Tall, strong, well-mannered, and the only child of a well-to-do businessman. If she can hold on to this guy and keeps him happy, she’ll be set for life. I already catch myself dreaming of the beautiful grandchildren they’ll give me.”

“And that, they did,” she smiled. “But then again, they first had you.” Audrey added as she stuck out her tongue and wiggled her butt.

“So, that’s Dad then?” I asked, ignoring both her gibe and the effect of that wiggle on my worn-out cock.

“I guess so, unless she was dating another Michael at the same time.”

She skipped a few pages and resumed her story.

“Donna and Michael dropped by unannounced. She said she had great news. Michael has proposed to her, and she said yes! I’m so happy for Donna; I’m sure it’s true love. I can see it in his eyes, and eyes don’t lie. Whenever he looks at her, his brown eyes have the same look as Donald used to have when we were together.”
