Sunday
The next morning, I was woken by my sister. She was still wearing her nightgown, and her hair was an auburn mess. I could see she hadn’t gotten much sleep last night, but even in this state, she looked beautiful to me.
“They did it! You were right, Nan and Donald had sex together,” Audrey said before I could even greet her.
It took a second or two to process what she said.
“Told you so,” I yawned.
“Whatever,” Audrey said as she sat down on my bed. “Here, I’ll read it to you.”
“Wait, get inside, you’ll get cold if you don’t,” I said, folding back the duvet.
Audrey hesitated for a second and then got in bed with me. Luckily, it was Sunday morning, and our parents were at our grandmother’s house again.
“Now, you just keep your hands on top of the blanket, okay? There’s gonna be no jacking off until I’m gone,” Audrey said as she crawled next to me and opened the diary.
Her feminine scent was intoxicating. I could already feel something stirring between my legs. “Just start reading,” I said.
“Okay, listen. It’s about a month or two after the last story. They are home alone, and Nan has just jacked him off.”
“He wiped his stuff off my boobs and played a little with my kitty. Suddenly, he stopped and looked at me funny. I asked what it was, and he said he wanted to have sex with me. I asked him if he knew how to do it.
“He said we could do it like Spot did with the neighbor’s dog. He said sex was supposed to be the best, much better even than anything we had done so far. He promised he would pull out before he’d shoot his stuff, so I couldn’t get pregnant. I said I wasn’t sure, but if he really wanted, we could try it.
“He got on his knees behind me and put his hands on my waist. His dick poked at my legs and butt a few times, so I reached out and helped it find my kitty. The next time Donny pushed, the tip nudged between the folds, and then it squeezed into me. Donny grabbed my waist even more firmly, and as he pulled me against his body, his penis speared deep into my kitty. It hurt a lot, and I asked him to stop, but Donny said it was too good and pushed his dick even deeper. The pain got even worse as he started to move in and out. Thankfully, he pulled out soon, and then I felt his stuff on my back.
“Donny said it really was the best feeling ever, and he wanted to do it again later. I told him it had hurt a lot and that I didn’t want him to put his dick in my kitty again. I could see his disappointment when I said that. I hope he is not angry about it and wants to stop playing.”
“That’s too bad,” I said. “I bet they could have had lots of fun together.”
“Well, this is what she writes the next day.”
“Dear diary,
My kitty is still sore, and there was blood in my knickers from what Donny did last night. I don’t think you’re supposed to put a dick in there like that. I hope Donny will still play with me if I do not let him put it in my kitty. Just kissing and using our hands is much nicer.”
“So, that’s it?” I asked when she stopped reading.
“Of course not, you didn’t think Donald would give up that easily, now that he’s had his first taste of pussy?”
“No,” I said. I knew I wouldn’t.
Audrey nodded.
“So, they continued fucking?” I asked.
“Not immediately, but eventually, yes. But they had also a lot of fun in between.”
Audrey leafed through the pages and started reading again.
“Donny came to my room again and asked if I wanted to fool around again. I rubbed his dick while he rubbed my kitty until I climaxed. Then he asked if we could have sex again, and I said it still hurt. He was a bit disappointed, but he wasn’t angry. He said that if I did not want to do it, I wouldn’t have to. He’s so sweet! It almost made me sorry I didn’t let him.
“I said I wanted to apologize to his dick and gave it a kiss. Donny said it felt nice and asked me to kiss it again. I kissed again, and this time I got some of the slimy stuff in my mouth. It wasn’t gross at all. In fact, it tasted kind of nice, so I did it again and again, tasting more of his stuff. Between kisses, I licked the tip with my tongue. Donny groaned loudly and said I had to do that again, so I did it a few more times. Then I took his dick in my mouth and sucked on it. Suddenly his penis pulsed, and his stuff shot in my mouth.
“I nearly chocked as his first shot hit the back of my throat. Just as I gasped for air, Donny’s dick pulsed again, and this time his stuff sprayed all over my face. I quickly closed my mouth again and let him fill my mouth with the thick, gooey stuff. It tasted a little bitter in my mouth, but I was happy Donny loved it this much. Later, he said that when I sucked on his dick, it felt almost as good as when it was in my kitty.”
I was getting dangerously aroused now. My cock was as hard as it had ever been and probably leaking lots of precum as well. I was going to have to readjust myself soon, before I would violate my sister with my erection. The little devil on my shoulder was telling me to just let it happen and see how she’d react, while the little angel had been screaming ‘stop’ for so long, his voice was almost gone. Still, I managed to behave and listen to the story.
“He said he wanted to kiss me down there too, like I had kissed him. I said my kitty was not like a dick, which you could suck on, but he wanted to try it anyway. He got between my legs and sniffed. Fortunately, I had bathed just before, and he liked the smell enough to close in and he touched my folds with his tongue. He said it didn’t taste bad at all and licked me again. When he licked the top of my slit and his tongue touched my little button, I gasped. It felt so neat! He knew he had struck gold and he planted his lips on it and sucked.
“It was like an explosion of pleasure when he sucked softly and moved his tongue around my sensitive nub. Soon I was panting and shaking as powerful waves of unbelievable delight raced through my body. Donny kept kissing and sucking and licking long enough for me to climax another time. It was the best thing ever.
“After this, Donny stopped licking and kissed me on the mouth. I could taste my wetness on his lips. I was surprised, as it really tasted nice, a little like the sweet clear stuff his penis had leaked when I first started sucking it.
My kitty was glowing for a long time, long after Donny had gone to his room. I can’t believe something can feel this good. I will definitely have to tell this to Livvy, maybe I’ll try licking her the next time we sleep over.”
“And they stuck to oral sex after that?” I asked, after she stopped reading.
“Yes, well at least for the next few weeks.”
“Well ... I guess that can be nice too” I said a little disappointed, but hopeful for the future.
“Nice?”
“Yes, don’t you think it’s nice to have your pussy licked?” I teased.
“Uh, yes of course” she stammered, embarrassed.
“Maybe your three guys just didn’t do it right” I pressed on.
“They were ... Just shut up and listen, okay?”
I chuckled softly.
“So ... what about Liv then?” I asked.
“Hmm?”
“Did they ever...?”
“Oh, yeah. A lot.”
“I would love to hear about that”
“I thought so, but wouldn’t you rather hear about when she started fucking Donald again?”
“Sure”
“Dear diary
“Donny and I had sex again last night, and it was great!!
“He came to my room after Mom and Dad went to bed and asked me if we could try to have sex again. I agreed, but only if he made my kitty feel good first, and he would pull out if it hurt again. He promised to do so.
“He got between my legs and licked me for a long time. It was the best, especially when he pushed two fingers inside me and moved them in and out while he licked my nub at the same time. I never knew it could be this nice to have something inside my kitty, so I got on my hands and knees and said he could try to put it in.
“My kitty was all wet and slick from his licking, so it didn’t hurt at all when he pushed into me. I could feel his hips pressed against my butt, and I knew I had his dick all the way inside me. He still stretched me, but this time it felt really nice, and when he started to move slowly in and out, it was just fantastic. His dick reached every good spot and rubbed my entire kitty with every push. I couldn’t help but moan softly.
“Donny stopped moving and asked if he was hurting me. I said he wasn’t hurting me, that I loved what he was doing. Hearing this, he started going again, a little faster and harder now. I started moaning because it felt so unbelievably good. He was moving in and out really hard, so hard that my arms gave way, and I almost fell over. I just lay there with my face in the pillows while he kept going. Soon he was panting and groaning like he does before he’s going to shoot. I wanted it to last longer, and so did he, but he had to pull out.
“After he had finished shooting, Donny slumped on the bed and said he loved me. I said I loved him too, and we kissed.
“I asked Olivia if she knew how to get hold of some condoms, but she didn’t. I had told her about the sex I had with my ‘boyfriend’ and that I had enjoyed it so much. She said she knew I would love it. I told her how much I hated that he always had to pull out, just when it was getting good. I said that if I had some condoms, he wouldn’t have to pull out so soon and then, maybe I’d get to feel good too.
“Olivia said that her sister Eleanor knew a way to have sex without the need for him to pull out, and still not get pregnant. I said I’d very much like to know how to do that. We asked Eleanor and she told us her secret, that there are only a few days of each monthly cycle during which a girl is fertile. If you know these days, then the other days are safe. It sounded like a load of hogwash to me, but Eleanor assured us that she had sex like a hundred times, with eight different boys and she never got pregnant.
“I have decided to trust Eleanor and just go for it. I checked, and it is almost four weeks since my monthlies, so it should be safe right now. I will try it tomorrow morning when Mom and Dad are feeding the animals. I can hardly wait!
“It was great! I told Donny I wanted to have sex with him again and that I didn’t want him to pull out this time. He didn’t dare to at first, but when I explained to him everything Eleanor had told, he said he wanted to try it too. He humped me for a long time, much longer than he would normally have. Then he grabbed me even firmer than before and pushed his dick deep inside me. He grunted and shook and then I felt his hot stuff flowing in my belly.
“As I write this at my desk, it’s like I can still feel him inside me. Sex is so much better when he can shoot his stuff in my kitty. It feels great and I don’t have to clean up afterward. I think I want to do it like this forever.”
“See, I told you. She just needed to get laid.” I said.
“Yes, but ... Her own brother?”
“Why not? It’s perfect. Nan and Donny clearly love each other, and they both like doing it. And the best thing is, they already live together.”
“It’s wrong,” Audrey said weakly, as if she didn’t believe it herself.
“People who say it is wrong just never had a hot sister,” I stated.
Audrey laid the book on the floor and turned around, facing me. She looked at me, her deep brown eyes looking into mine, searching for something.
“Like Nan, you mean?” she asked.
“Or ... like you,” I replied. As I heard these words leave my lips, I wanted to kick myself. What was I doing? Yes, I was attracted to my little sister, and not a little. I had been as long as I can remember, but I had vowed never to act upon it. Now I had spooked her; I could see it.
“Do you really think you could have sex with your sister?” she asked after a while.
“Are you trying to seduce me?” I asked playfully, trying to lighten the atmosphere a little.
“NO!” she yelled, turning red in embarrassment.
There was another uncomfortable silence. Until this moment, she too had been joking. Now I didn’t know anymore.
“Well, could you?” she whispered, barely audible. She sounded sincere and extremely vulnerable and, in a way, also extremely endearing. I was compelled to tell her the truth.
“I don’t know. I can’t say I have never thought about it. Do you think you could?”
“If my brother would be as handsome as you...” she said in a husky voice, her hand trailing down the band of my V-neck. Now she was definitely flirting with me. I was suddenly aware of how close her face was. Unconsciously, we moved even closer, and our lips met. It wasn’t weird to kiss Audrey. My sister and I had been flirting for so long; it was inescapable. It had to happen one day. As it turned out, we both liked it a lot. Our lips locked for at least ten minutes while our tongues played and our hands explored our heated bodies.
At some time during our kiss, Audrey had rolled on top of me, and my hands had invaded the forbidden and enticing realm covered by her nighty. They moved over her soft skin, ever higher until they reached her perfect round breasts and her little erect nipples. She moaned softly and pressed her crotch down on my painfully swollen cock as I pinched the sensitive points. Only a few thin layers of fabric separated us, and I could feel the heat from her sex as she ground her pussy up and down the length of my shaft.
“I need you inside me,” she gasped as we finally broke our kiss. Her eyes were burning with lust.
“I want you too,” I whispered back.
It was like a wet dream came true. Still on top of me, Audrey sat upright, and with one sweep of her arm, she sent her gown flying. She was truly gorgeous, far more beautiful even than she had been in my dreams. Just perfect. Everything about her was perfect: her skin, her breasts, her smile, and her eyes. She was the most perfect girl I could ever imagine, and she was my own sister.
My hands reached out and grasped her slender waist, caressing her from her round ass to her firm breasts. She moaned softly as I fondled her tits and tweaked the pink tips. While I was enjoying my sister’s naked breasts, she was still struggling to remove the shirt I wore for pajamas.
A bit reluctantly, I let go of the magnificent pair and sat up a little. Audrey now easily pulled off my shirt and then covered my chest in little kisses as she progressed downwards. She hooked her fingers in the waistband of my boxer shorts and pulled them down. She smiled in delight as my erection sprang up and slapped against my stomach. I knew what she planned to do next, but I wasn’t going to let her. My first orgasm inside her would not be in her mouth.
She looked at me hungrily and licked her red lips, but just as she was about to take me into her mouth, I grabbed her and before she knew what happened, she was on her back on the mattress. Another second later, my sister’s panties were somewhere on the floor and I was between her legs, lapping at her nectarous pussy. Soon Audrey had all but forgotten her intentions and was crying out in pleasure.
