I kept my word and nothing else was said about the diary for the next two months, although it was always on my mind, and I’m sure, hers as well. School let out for the summer and this meant Dionne and I spent even more time together. Things seemed to get back to normal between us, yet there always was an undercurrent of tension whenever we were alone together.
She broke it off with Donny and the next day he came over to talk to her. I met him in the drive and told him that she had told me what had happened. I told him if he ever came over again, or even called her, that I was going to put him into the hospital, then I was going to tell my dad and that he would probably kill him. Donny apologized profusely and then left. I was sure that was the last we would ever see of him.
All this time, however, my carnal urges for my sister grew stronger and stronger. It got to the point where I was jerking off thinking of her at least once a day. I had begun to use her panties again to relieve myself, but now I wasn’t putting them back in her drawer. I was keeping them, hiding them in a duffel bag in the bottom of my closet. That way, I didn’t have to wait until she wasn’t around and sneak into her room. I don’t know if she was beginning to miss them or not but she never said anything if she did. She started filling my thoughts almost all the time, whether I was awake or not. I lost interest in everything else. All I could think about was fucking my sister. I knew I would have to act before long.
Then one fateful day, my opportunity finally arose. It was a Tuesday. We were alone in the house together as usual. I was in the den watching TV when Dionne walked through wearing a bikini with a beach towel slung over her shoulder. She said she was going to lay out by the pool and work on her tan. Immediately, the wheels in my head began to turn. I waited for her to get settled outside and then I went into the half bath in my parents’ room. It had a small window that overlooked the deck and pool. I went to the window, parted the curtains slightly and looked out.
My sister was laying on the towel, face down. She had untied her bikini top and I could see the sides of her breasts heaving out from either side of her. She was laying in a vertical line with my eyesight, giving me a wonderful view of her back, ass and legs. She had hiked up her bikini bottom over each ass cheek for maximum sunning. Instinctively, my hand went into my gym shorts and I began to pull at my already enlarged organ. Sweat had popped out across her back and legs, coating her in a mesmerizing sheen of dew. How I wanted to lick that sweat off her body! Her already tanned legs were spread a little, and I could just make out the contours of her pussy beneath her swimwear. And that ass! Each cheek had a well-defined tan line and she was rocking her hips back and forth in time with the music she was listening to. It would have been the easiest thing in the world for me to have whacked off right then, watching this incredible sight. But I didn’t. I had other intentions.
Ever since I decided that I was going to have to take action, I had been keeping up as best I could with Dionne’s menstrual cycles. When she wasn’t around I would check the trash can in her room for feminine napkin wrappers. By doing this I pretty much knew when she was on her period and when she wasn’t. It had been about two weeks since I last saw one in her trash, and I knew now would be as good a time as any for me to make my move. I was nervous as hell, but horny enough and frustrated enough to decide today was the day. As I watched, Dionne rolled over onto her back, and for a brief second I caught a glimpse of her gorgeous tits before she lay her top across them. That clinched it. I was going for it!
I pulled back the sliding glass door, and with a glass of lemonade in my hand, walked out and stood over her on the deck. She sat up and asked if I was going swimming. I said no, that it was time for us to have a talk. She looked up at me puzzled for an instant, then I saw a look of recognition on her face and she nodded. I sat down beside her and dangled my feet into the water of the pool. Holding her top with one hand she slid forward and did the same.
“What are we going to do about this?” I asked.
“I don’t know,” she said, “have you been thinking about it?”
“A lot.” I replied.
“Me too. I just don’t want you to tell mom or dad, they’d kill me.” Dionne said.
“That’s right. They would.” I offered her my glass and she took it, sucking on the same straw I had used. My dick lurched upward at the sight of her full lips wrapped around the shaft.
“Well, what do you want me to do… I could wash your car for the next hundred years or something,” she said, looking at me. I just shook my head.
“What, then…” She said “…I don’t have a lot of money, but if you want, I could give you what I have.”
“I don’t want your money Dee Dee,” I replied, looking back at her. “But my silence ought to be worth something to you.”
“It is… you know it is. Just tell me what you want me to do,” she implored.
I squinted my eyes as I said, “I don’t know… I’m not sure if you’re ready for this.”
She elbowed me in the ribs. “Would you tell me already?!”
I looked at her and hesitated. I was at the threshold. Did I dare step over the line, not knowing what the consequences would be? I took a deep breath and went for it, but it seemed like someone else was saying my next remark.
“I want you to give me the same thing you gave Donny.”
If I had told her God was a lobster she couldn’t have looked at me with a stranger look.
“What… do… you… mean?” She finally stammered out.
I dropped my eyes from hers and I looked down. Her hand holding her top in place had fallen a little and I could see the tops of the dark circles at the ends of her tits. My gaze wandered further down to her flat stomach, which I noticed wasn’t flexing in and out. She was holding her breath. Just beneath her navel I could make out the fine blonde hairs that led down to her bush and I could imagine the treasure underneath her bikini panty. I was willing to risk anything to obtain that treasure.
“I want to have sex with you,” I at last said. For what seemed an eternity she didn’t respond.
“You’re just joking, right… You’re not serious, are you?” Her voice was weak and low. Her eyes were opened wide.
“I’m dead serious.” Having at last vocalized my lust seemed to restore my determination. “If you want me to keep quiet about what I found in the diary you’re going to have to fuck me.”
The “f” word seemed to send her reeling. She momentarily lost her motor skills and the top fell into her lap. I looked appreciatively at her big boobs for a second before she regained some control and pulled her top back over her tits.
“But… but… you’re my brother… I’m your sister… we can’t do that.” Her voice now had a pleading quality to it.
“You did it with a guy who you had only been out with a couple of times,” I reminded her, “you can do it with a guy you’ve grown up with just as well.”
She tried to set the glass of lemonade down beside her but it tipped over. She drew her legs out of the water and pulled them up to her. She wrapped her arms around her legs and dropped her head onto her knees. I thought she was going to cry.
“I’ve been wanting to tell you about how I felt for a long time,” I said, “but I was never sure how to approach you about it. I love you. Not just the way a brother loves his sister, but the other way. The way mom and dad love each other. I can’t help this. If we hadn’t been born into the same family what I’m telling you wouldn’t be a big deal. It’s not my fault we are brother and sister. I’ve been feeling like this for a long time, and it’s driving me out of my mind. Don’t tell me you’ve never wondered what it would be like to be with me.”
She looked at me again. She was crying, just a little. “I don’t know… maybe… but I couldn’t… you’re my big brother.”
I edged up against her and put my arm around her bare shoulder. My palm was sweating.
“Do you love me?” I asked.
“Yes, you know I do,” she answered.
“Do you love me enough to show me that you love me?”
“I… I… don’t know. If you weren’t my brother… maybe.”
“Look at this way,” I said, “I’ve loved you for sixteen years. I was the first boy to ever love you. If you do love me, and I know you do, you have loved me practically your whole life. So what is wrong with two people who love each other expressing how they feel by showing each other.”
She had pulled away slightly when I put my arm around her. Now she relaxed a little and settled back into my embrace. I could tell she was contemplating what I had said.
“If we do this…” Just the trace of a smile crossed her lips, “do you swear your not going to tell mom and dad about the diary?”
“What could I say… Dionne wrote in her diary about having sex with a guy, so I talked her into having sex with me, too?” I said sarcastically.
She laughed a little, and I slipped my hand down around her waist.
“And you promise your not going to tell your friends, or anybody? If anyone ever found out…”
“No one is ever going to know. This is just a onetime thing, if you want, and it will be just between you and me.”
“If I agree to it, when do you want to?” I thought my cock was going to explode! I was within sight of fulfilling my deepest fantasy!
“Now… mom and dad won’t be home for hours yet. We’ve got the whole house to ourselves.” I said. My heart, not to mention my prick, was pounding.
She didn’t say anything. She just sat there with an embarrassed smile on her face.
“C’mon…” I nudged her, “it’s just sex. It’s just skin touching skin. There won’t be any lightning bolts come down and strike us or anything. It’s just two people making each other feel good. I know you didn’t enjoy it the first time. That’s because that dipshit did it wrong and you weren’t ready. This time it will be different, I promise. It won’t hurt and I won’t rush you. It’ll be good.” With my right hand I turned her face to look at me.
“I’m your big brother, remember? I wouldn’t do anything to hurt you.”
She sighed deeply. “Okay, big brother… let’s go inside.”
