Monday
After just an hour of sleep, I was woken again by Audrey crawling into my bed. In the dim moonlight, I could see her eyes were swollen and red. Without saying anything, she grabbed my arm and draped it over her chest, crawling snugly against me. Again, my nostrils filled with that wonderful scent.
She was sniveling softly.
“What’s wrong, baby?” I whispered.
“It’s Nan. It’s bad.”
“What is it?” I asked.
“Well ... remember you were worried about her getting pregnant?”
“Yes?”
“I guess you were right again, and this is what happened.”
She flicked on a light and handed me the diary, pointing me to where I should start reading.
“Dear diary, I think I’m getting sick. It’s like I don’t have any energy, and this morning I had to throw up again. At first, I thought I ate something wrong again, but I can’t think of what that might have been. If I don’t get better soon, I’ll ask Mom.”
“Ah, and that’s how Mom came to be?”
“No ... Mom wasn’t born for another five years. Unless she’s been lying about her age and is really 50.”
“What happened then?”
“The story continues on the next page. But it’s not a cheerful story.”
“Dear diary, I’m in so much trouble! I asked Mom about me being tired and sick all the time, and she took me to the doctor. He asked me a few questions, and when I told him about the games that Donald and I played, he said he thought I might be pregnant! He told me to take off my sweater and lift my shirt. He felt my stomach and listened, and then he told me there was a baby growing inside me! The doctor gave me a leaflet. It’s called ‘So you are pregnant’ and said I’d better read it.
“Mom was so angry! She didn’t speak to me all the way home and just sent me to my room to wait for Daddy and Donald to come home. I really don’t know what to do.”
“Oh shit, this can’t be good,” I sighed.
“No. I guess our great-grandparents weren’t as fond of incest as you are.”
“Maybe they should have tried it,” I said, planting soft kisses in my sister’s neck.
Audrey once again grabbed my arm and pressed it against her chest.
“Well, I’m glad I’m on the pill just the same.”
“I’m dead. My life is officially over. Dad almost exploded when Mom told him. I’ve never seen him so angry! He beat Donald so hard he was crying, and then he ordered him to get in the car. I don’t know where they are taking him; they wouldn’t tell me. They hardly spoke to me anyway. Mom told me to go back to my room and wait here. When Dad is back, they will decide what they are going to do with me.”
“Look, the paper is all wrinkled. She was crying as she wrote this.” Audrey pointed out.
“Yes, it seems like it. The ink has run too.”
Audrey didn’t say anything for a while, just lay silently on her back, staring at the ceiling. In the early morning silence, the only thing I could hear was her breathing.
“What happened next?” I asked after a few minutes of silence. “Did they kick her out too?”
“I don’t know.”
“Wanna stay here and read?”
Audrey nodded and grabbed my arm again. I drew her close to me, and we read the diary together.
“I read the leaflet. It explained how a boy’s sperm and a girl’s egg formed a baby. It didn’t say how those two got together, but I guess that’s what happens when he shoots his stuff in a girl’s ‘vagina.’
It said the baby would be born nine months after conception. I guess that means having sex. The first thing that would happen was that my monthlies would stop. I hadn’t paid much attention to that, but when I looked in my diary, I saw it’s been almost three months now. The last time it happened was three weeks after Donny first shot his stuff inside me. According to the book, that means the baby is growing for about two months now. Pretty soon, I should be able to feel it move.”
“But if she’s really pregnant, and it isn’t Mom ... Who is she pregnant with?” I asked.
“I don’t know.”
“Did they abort it?”
“Not likely. Her parents are very religious. And this is nineteen sixty-seven, so abortion is still illegal.”
“So, what happened next?”
Audrey flipped the page, and we quietly read on as the story unfolded.
“It was a long time before Daddy came back. Donny wasn’t with him anymore, so wherever he took him, I guess he had to stay there. The only thing he said to me was to go to my room. Mom and Dad were arguing loudly in the kitchen. I could hear Dad’s booming voice and the fainter sound of Mom’s. I cannot hear what they were saying; a single word every now and then is all I got. One word I did hear clearly. It was Dad calling me a whore.
“They’re silent now, I’m afraid of what they have decided.”
The rest of the page was blank.
Audrey suddenly let the book fall on the mattress. I could see there were tears in her eyes. I wanted to comfort her, but didn’t know what to say. I simply wrapped my arms around her and asked her to continue.
“Dad came into my room and locked the door behind him. He unbuckled his belt without saying anything. He just looked at me with hate and disgust in his eyes. With the belt in his hand, he told me to take off my dress and panties. I was so scared, I was crying and trembling as I took off my clothes.
“He told me to stop crying and made me stand there before him, wearing nothing but my bra. He then ordered me to turn around and place my hands on the mattress. I did as he said and waited for the pain of his belt to hit my back, but he didn’t lash me. Instead, he put his hand between my legs and roughly rubbed his fingers through my kitty. He said that if I wanted to be a whore, he might as well fuck me too.
“He got behind me, and I felt his dick push against my kitty. He forced the tip into my hole, but my body wasn’t ready, and it didn’t go in easily. He spat on my kitty and pushed again. This time, it went in. It hurt, and I fell on the bed. He cursed and hit me with his belt as I lay there. Then he told me to stop crying and pulled me back on my feet. He spat on my kitty once more and pushed his dick back in me, pushed until he was all the way inside. The pain never stopped as he humped me for a long time. It felt like hours before he grunted, and I felt his stuff gush inside me.
“When he was done, he pulled up his pants and walked to the door. He told me to clean up and said that I could never tell anyone what happened. Then he left and locked the door. As I lay in bed, I cried. The marks on my back were burning, and I was completely raw inside.
“I had to stay in my room all day today. I slept a lot so I wouldn’t have to feel the pain. My kitty is still sore from what he did yesterday. I didn’t tell Mom what he did, but I think she knew. She didn’t say much, but she gave me a tube of cream to soothe the tender skin. He didn’t speak to me at all. He just looked at me with hateful eyes, which is even worse than the pain.
“I dared to ask Mom if she knew where Donald is. Mom just said he was gone and that I would never see him again. I asked what would happen to me, and she said I was going to move in with Aunt Barbara as soon as my belly begins to grow. It is already visible, but I don’t want them to know that. I don’t want to have to move away and lose Liv too. She’s the only one who is still nice to me. I’m not allowed to see her after school, but we can still talk during recess. I told her everything. She’s the only one who tries to comfort me when I cry for Donny and who prays with me for my future. If I didn’t have her, I’d be all alone.”
After this, Nan’s writing began to decrease every day, even skipping days altogether. There probably is little to write about when you are locked in your room. The next entry was dated more than a week later.
“It’s been two months now since Donny has gone. Dad still comes to my room sometimes and has sex with me. If I don’t obey, he hits me. He doesn’t care if he is hurting me; he just wants to shoot his stuff. Other than that, he doesn’t touch me or talk to me. I’m glad the baby is growing fast, and I’ll soon be leaving this hellhole.”
Then, on the next page, she wrote:
“Mom told me that my belly is getting bigger, and soon people will be able to see I’m pregnant. I’m not allowed to go to school anymore, and next week I’ll be going to Aunt Barbara’s. I asked her what would happen when the baby comes.
Mom’s voice cracked, and I saw tears in her eyes. She just said she was sorry and went away.”
I felt the urge to say something, but couldn’t find the words. Fortunately, the story continued in a slightly more optimistic tone.
“Aunt Barbara is actually quite nice. She’s much nicer to me than my parents. She told me that it was a sin to sleep with a man if you weren’t properly married, and an even greater sin to sleep with your own brother. But she also told me she couldn’t blame us, as we didn’t know what we were doing.
“She also knew what happened to Donny. She said Dad had enlisted him in the Navy. She wouldn’t tell me in what base he is, or maybe she really doesn’t know. Anyway, I’ll never be able to find him.
“I asked her if she knew what was going to happen to my baby, as Mom didn’t want to tell me. Barbara looked at me the same way Mom had done. I begged her, telling her I had to know. Then she explained that when it is time for the baby to come, I will be taken to a home for unwed mothers. There I will give birth and nurse the baby until they have found a new family for him.
I started crying when I heard that I would have to give my child up for adoption. I never cried this hard or this long.
“All this time Aunt Barbara held me tight, telling me to let it all out. When I was finally cried out, she made us tea. I said I didn’t want to give up the baby and she said she knew how I felt. She explained that I had no choice, and that it would be the best thing to do, for me and the baby. Because, if I was unmarried, the child would have to grow up without a father, and there was no chance I’d ever find a man if I had a child already. She is probably right, but it doesn’t change my mind one bit. It is MY child and MY life.
“I asked her if she’d allow Liv to come visit me. She said she’d think about it. I hope she will.”
“She’s stopped writing again,” Audrey said, flipping the pages and scanning the few written lines of text. “I guess she has nothing to write about. No school, no friends, nothing to do. The only thing she does is read and sleep, it’s depressing.”
“It must be horrible for her. Can’t she run away or something?”
“Where could she run off to? She has no money, doesn’t know anybody, and is pregnant. She’d die for certain.”
“Yes, but still...”
“I know.”
I felt really awful. I could never have guessed our dear, sweet grandmother had such a woeful past. There was nothing anyone could do about it now, and I just hoped she had at least found peace and happiness. At the same time, I really wanted to know how the story would continue.
But even though I honestly wanted to learn more, I was struggling to stay awake, and so did Audrey. She was yawning, and I could see her eyes were getting heavy too.
“Can I sleep with you tonight?” she asked.
“I would love that, but what about Mom and Dad? What if they catch us?”
“They won’t. I’ll set the alarm for six. I’ll go to my bed then.”
“Make it seven.”
She laid the book down on the ground, grabbed my arm, and draped it firmly around her. Then she turned off the light and whispered, “Goodnight.” I kissed her in the neck and closed my eyes, breathing in her scent as I drifted off to sleep.
Much too soon, I was woken by soft, tinny music coming from my alarm clock. I was spooning my sister, who was still sleeping, despite the alarm. She was looking as beautiful as ever, and I would have loved to watch her sleep a little longer, but we were cutting it close already. In fifteen minutes, Dad would be getting ready for work, and Mom would get up soon after.
I gently shook Audrey and watched as she opened her eyes.
“Wake up, baby,” I whispered.
“Hmmm?” she groaned.
“You have to get up.”
“Why?” she murmured, sleepy.
“It’s seven o’clock. You have to go to your own bed, or they’ll see us together.”
“But I want to stay with you.”
“Get up, baby.”
She finally got the message and folded back the duvet.
“Can I come back later?” she asked feebly.
“Yes, baby. But wait until Mom and Dad are out. I’ll be waiting for you.”
“I love you, Chuck.”
“I love you too.”
Shortly after our parents had left, Audrey came back to my room, wearing nothing but a pair of little lime-green panties. She had showered, and her long, waving hair barely covered her perky breasts. She looked like she had just walked out of a precious old painting or maybe a playboy magazine. But what made her even more beautiful was the way she was radiating as a woman in love.
She crawled onto my bed and greeted me with a long kiss.
“I liked sleeping with you,” she smiled.
“Me too. You look so beautiful when you’re sleeping.”
“You’re sweet.”
“You’re beautiful like this too,” I added, as I caressed her round ass.
“Really?” she asked playfully, as she sat upright and threw her hair back, exposing her immaculate breasts. “I thought you might like it.”
She moved forward again and kissed me again.
“I wish we could stay like this forever,” she sighed.
“Me too,” I said, drawing a finger between her breasts and over her smooth belly. “But Mom and Dad ... they would go ballistic if they caught us.”
“I know...”
“Speaking of which...” she said, “Is the diary still here?”
“I think it’s under the bed.”
“Would you mind if I read it here?”
“Of course not. Do whatever you want, baby.”
I’d rather snuggle a little longer and maybe do a little more, but I could see that wasn’t in the cards right now, and frankly, her mentioning the diary kind of killed the mood for me too.
“Thanks.”
Audrey put on a loose sweater and began to read quietly while she lay in my arms. Then she spoke again.
“Dear diary,
“I have a beautiful son. I’m a mommy!
“I never knew it was possible to love someone as much as I love him. He’s so beautiful, so small, and so sweet. He even has his father’s brown eyes.
“Two days ago, they took me to the hospital. My water had broken, and the contractions had begun. It hurt like hell, but it was nothing compared to when the baby came out of my vagina. It took hours to push him out, and they say I bled a lot. Finally, the nurse grabbed him and lifted him up. He screamed. It was a sound unlike I had ever heard before, and my maternal instincts came alive. I just had to hold him in my arms.
“The nurse cut his umbilical cord and wrapped him in towels. The moment she got out of my sight, I knew I’d never see him again and screamed, kicked, and cursed everyone. The nurse came back immediately and laid the baby against me.
“She told me he was a beautiful, healthy little boy and handed him to me...”
As Audrey was lying in my arms and reading the story, her voice cracked.
” ... they tell me not to get too attached to him. They say he’s mine for only a short time, and then they’ll have to take him away, and I’ll never see him again. They might as well tell the sun not to shine. How can I not get attached to my own son? How can I look into his eyes, smile at him, feed him, and not love him?”
Nan wrote very little. On most days, it was only a couple of lines about how sweet and beautiful the baby was and how fast he was growing. What she didn’t write about, but was clearly weighing heavily on her, was the fate that was looming over them. With every day that passed and every ounce little Donny gained, the moment she would have to give him up neared a little bit more. A few pages later came the moment we all dreaded.
“Today, sister Diane told me they had found a family that was willing to adopt Donny. She said they were good people, rich too. She said I was lucky these nice people wanted to take care of my son. Stupid bitch.”
Audrey flipped the page again. The date showed three more weeks had passed since the previous entry.
“They have stolen my baby. Two nuns held me while the third took my baby and left. I don’t understand these nuns. How can they be such caring people and be so cruel at the same time? I hope those nuns will burn in hell for what they’ve done to me. I really do.”
My sister’s voice broke as she read that last part. I was feeling chocked up too. Although all of this had happened some fifty years ago, I still felt I had to do something to fight this injustice. Right now, all I could do was let Audrey know I was there and was feeling with her. Holding her hand was the least I could do.
“Go on, tell me how she’s doing.”
“I am back at Aunt Barbara’s again. I don’t know what will happen next, and I don’t care either. I miss him so much. I feel hollow. There’s not a second that I don’t think of him. The doctor gave me pills that are supposed to make it easier for me. All they do is make me feel numb. Every day is the same in this hell.
