Tuesday
As much as I hated it, I really had to return to college. Early in the morning, while the whole world was still asleep, I had topped off Audrey’s pussy one last time. She then went back to her own room, but not before she made me promise I’d be back on Friday.
A few hours later, I said goodbye to my family and got in my car. As I drove away, I suddenly felt like crying. I missed Audrey already, and every mile I traveled was one more mile between us. I couldn’t believe how hard it was to be away from her, even for just three and a half days.
When I arrived on campus, I went straight to my lectures. But even there, I could not get Audrey out of my mind. While the professor was talking, I took out my phone and wrote my sister a little message. I got an answer immediately. She was missing me too. We exchanged about a hundred more messages and I even received a couple of naughty pictures. It did lighten my mood a bit, but what I missed most was just being with her, feeling her, and smelling her. No amount of technology could fix that.
At night, she called me on the phone, and we talked for hours about everything and, of course, she kept me updated on the sexual adventures Nan shared with her new husband. Not surprisingly, these stories got me so hot, I had to jack my cock while I listened. My sister then joined me and our conversation shifted to full-blown phone sex.
It wasn’t long before Audrey told me about Nan being pregnant again. This time it was 1971, and the baby was a girl, our mother. It was already late when she called, but I was glad to hear her voice again. Thankfully, she spared me the details of labor and all the diaper changes, but she did tell me an interesting detail.
“Did you ever realize that Mom is named after Donald?”
No, I hadn’t.
“Apparently, it was Grandpa’s idea. He thought they should call her Donna, after her missing half-brother and his father. Nan liked the idea, so they did.”
“Gee, I never ... thought,” I yawned, feeling very sleepy. It was past midnight already, and I would have to get up in less than 7 hours. I carefully excused myself and promised to call her tomorrow. We blew some kisses into the microphone, and then I hung up.
Friday
I couldn’t wait for today to come. When it finally arrived, I decided to skip the afternoon’s lectures and head home instead, and surprise my lover with an early arrival.
As luck had it, she was home alone and working on her computer as I walked into her room.
“Hey, you’re back,” she said, smiling as she held out her arms for an embrace and a long, hot kiss. God, how I had longed to inhale that scent again.
“I’ve missed you so much,” I whispered between kisses.
“I’ve missed you too,” she said, grinding her pussy against my crotch.
“Hey, I’ve got great news,” she said, grabbing my hand and leading me to my old room. “See?”
My whole room was filled with boxes and random stuff from Nan’s. I couldn’t even see my bed for all the junk. There was no way I was able to stay here.
“How’s this good news?” I asked.
“Because, as your loving sister, I selflessly offered to share my room and bed with you, and Mom accepted. Now we can sleep together all night, all the time!”
I immediately understood the implications of this situation. A smile formed on my face.
“That’s brilliant! Remember me to properly thank you tonight.”
“I know just the way you can thank me ... all night long.”
“Speaking of Mom and Dad ... where are they?”
“I don’t know. Gone,” she said with a naughty twinkle in her eye.
“Do you think there’s time for a quickie?” I asked.
“No ... but I’ll let you eat me,” she chuckled as she led me back to her room. She lay down on her back and spread her legs a little, flashing her white panties as she hiked up her short skirt. I pulled them off, and I was greeted by her pink pussy. I swear it was smiling.
I got on my knees between Audrey’s legs and closed in to give her moist lips a kiss, then licked and fingered her until I had gotten her so hot, she was begging me to fuck her. We made love like the long-lost lovers we were, frantic and rushed at first, then more slow and tender as our most urgent needs were filled.
An hour later, we were still in bed, sweaty and exhausted, but completely satisfied and more in love than ever.
“Are you still reading those diaries?” I asked as I spotted one of the books under her pillow.
“No, I haven’t had much time to read. Too much damned homework.”
“Anything good happen?” I yawned.
“Not really. I’ve told you about Mom, right? She writes mostly about her growing up. It’s actually not that interesting. I have pretty much skipped through most of this part. Maybe I’ll read it later when I’ve got more time.”
“So, nothing new?”
“Well ... Shelley was born, but you knew that of course ... Grandpa got a new job, but we knew that as well...” She picked up the book and leafed through its pages. “Wait, here is something you might like to know.”
“I wrote a letter to Aunt Barbara today. It is something I have been wanting to do for some time now, but I never dared to. I told her of my new life in the city and of my husband and our two daughters, but most of all I wanted to thank her for everything she has done for me, for taking care of me and also for saving my life. I also told her I don’t blame her for anything and apologized for running away without leaving a note. Finally, I included my address and asked her to write back, if she wanted. I must say, it feels really good to have finally done this, although I so feel a bit of anxiety as I await her answer.”
“And, did she write back?” I asked.
“Err ... yes, she did. Within days, actually. With a little extra too.”
“A little extra?”
“Uh-huh”
“I got a letter back from Barbara. Inside the envelope were also a couple of letters from Donald, all addressed to me. He writes that he met with Barbara and she told him everything she knew, up to the point where I left. He said no words can describe how sorry he is for everything that happened to me and writes he hopes I’m doing well. He also hopes the best for our son.
“He also explained what happened to him after our father took him away that day. He was in the Navy for four years, saw a lot of the world, and made a few promotions before he met his wife and settled down. He owns a little shop now, but he doesn’t say what kind. He married a woman named Brenda and they have two sons, Jim and Ronald, who are six and seven years old now. There were a few grainy photos of his wife and kids attached to the letter. They look nice. She does too.
“Every letter ended with his address and phone number, and that he’d love to hear from me. I think I will do that.”
“And, did she?”
“She did.”
“What happened?”
