It was a dark, and stormy night as lightning flashed throughout the old house. Thunder rattled the windows threatening to shake them right out of their panes. Boom, boom, boom went the deafening roar of thunder as Lily ran into my room in just her underwear, and dove into to my bed.
"I'm so afraid." she cried as she wrapped herself around me.
"Jesus you're shivering." I said, becoming acutely aware of her warm, almost naked body next to mine. It's okay. It's just a thunderstorm. I'm here with you."
We lay there in each others arms; her jumping at every thunder clap for half an hour, until the worst of the had storm passed. Finally, I heard her softly snoring. I too closed my eyes, and faded away.
I awoke somewhere around five. Our bodies were twisted together in a lovers embrace. We were not yet lovers at this point, but we shared an unspoken bond; a sexual need that we had denied for years. We had come close to fucking a couple times, but we had always stopped.
Her head was tucked into my chest as it rested on my arm which in turn was curled around to her opposite shoulder. My other arm was draped around her. My leg was between hers, while hers were both wrapped around my leg.
The warmth, and softness of her nineteen year old body is forever etched into my consciousness. I slid my free hand slowly down her back, around the curve of her bottom, and down her leg, and back up again. Her body was an exquisite masterpiece of femininity. I was already hard for her.
I lay there for an hour, just enjoying the feeling of having her curled up in my arms. Finally the morning dawned, and light of day begin to fill my room once more. She stirred, and her eyes popped open. She suddenly pulled her head away from my chest.
"What are you doing?"
"I didn't want to wake you. Do you have to get up right now? I was enjoying it."
"Ira, you know, I'm your sister, right?"
"Why does this feel so perfect? Why do you feel so good in my arms?"
She giggled the way excited girls do sometimes, and buried her head back into my chest hugging me again.
"I don't know." she softly said. "I feel it too."
She grabbed my aching cock which was straining against my underwear while simultaneously asking, "Are you hard?"
"Sorry. It just happened."
"Jesus you're huge."
"Um, thanks."
"David's is nowhere near that big," she said giving it a little squeeze causing my cock to pulsate in her grip before finally letting go.
David was her ex-boyfriend. It looked like things were going great for them, until she became pregnant than lost the baby. He blamed her for everything, and ghosted her. All of that had happened six months before.
She suddenly pushed her groin into mine as we embraced once more. I in return, pushed back. I think we both moaned.
"I want you, so bad Lily. You know I do" I moaned. "We've avoided each other for far too long."
"Ira, I'm afraid we're about to finally cross a line we can't uncross."
"We're grown adults. We can do what we both want to do?"
Our lips met, as we finally gave into pure unbridled, incestual lust. My hand slid up her back unhooking her bra with one twist of my fingers.
She rolled over thrusting her hips in the air to remove her panties. I quickly removed my underwear as well. As soon as I had finished removing them she was climbing on top of me pushing my cock down with her crotch.
My sister's breasts are not overly large. She's a tiny thing, but her breasts are really nice sized for her frame with silver dollar areolas. Her nipples are a little large in length and width, and beg to be sucked. I fondled her breasts rolling her nipples between my fingers and thumb while trying to work my cock upward.
I was struck by how smooth her pubic mound was. There was not a single bump, or razor stubble on her obviously bald cunt.
She began gyrating her hips, and working her pussy up, and down the length of my cock. I could feel my cock getting wet from her excessive pussy juice. It was pure carnal torture. The girl I had longed for since I was fifteen, was right there, her pussy against my cock positively begging to be fucked. All I could do was hope this wasn't an elaborate tease.
"Please don't tease me," I muttered. "I need you Lily."
She leaned forward to kiss me on the lips, as she did I felt my cock head slide between her pussy lips. I had never felt anything so amazing. All my attention was on pushing my cock in there, but once again she had blocked me. The only direction I could push my cock was upward, and she was in front of it.
"What do you want," she asked seductively.
"I want to fuck you."
"No, there something else you want to do even more."
"I want to cum."
"Where do you want to cum."
"Your pussy, I want to cum so deep in your pussy, Lily."
She kissed me slowly undulating her hips, so that the tip of my cock barely felt the opening of her hole.
"I'm on the pill," she whispered, "Cum in me Ira."
