I was relaxed and sharing Claire's warmth. I could feel her backside pressed against mine. Her t-shirt covered back, expanding and withdrawing with each breath.
I was also feeling her butt pressed against my lower back. Normally, I would have been weirded out by that contact. Even sleeping so close to Claire felt awkward, but I didn't care because I knew the alternative was freezing.
Before I knew it I passed out and reawakened sometime later that night. I realized quickly that what woke me was Claire's movements. She was changing her position, and it shook me slightly, enough to wake me.
I felt Claire's arm hug me, followed by her body pressing up against me. She was spooning me. I looked over my shoulder out of curiosity. I wondered if Claire was awake or sleeping.
Claire must've seen me look at her in the dark, so she said, "Sorry... This is better."
I didn't respond, neither agreeing nor denying. I just tried to fall back asleep. Very quickly, I found I loved being spooned like this by Claire. I felt safe and sound in her arms. My protective big sister, who allowed me to join her in her sleeping bag was now holding me so dearly. I was comfortable and I drifted to sleep straight away.
Once again, I was awakened in the night. Unfortunately, this time my arm had fallen asleep. I couldn't even feel my arm anymore as I tried to shake it awake. I was sleeping on my side for too long, cutting off the circulation, so I needed to adjust my position. I would have to turn to my other side.
Claire still clung onto my back and had her arm around me holding my chest. I had to turn and face her. Trying not to wake her, I turned slowly. My efforts were for not because Claire was woken up immediately by my movements.
"Sorry, arm fell asleep. I can't feel it," I told the groggy Claire.
"It's okay. Here we can sleep like this."
Claire grabbed my numb arm and flipped around, placing my arm around her shirt-covered tummy. We had traded positions, and now I was the big spoon. I held Claire in my arm, and she cuddled close to my chest. My hand rested on her firm belly.
Within minutes Claire seemed to have fallen back asleep, but I was unable to. I was cuddling with Claire, my kind older sister, holding her warm body against me. The natural smell of her hair filled my nostrils. I could feel every one of her breaths against my chest as her back expanded into me.
Claire moved backward, pressing up into my body further. We were connected by our warmth. It felt great to embrace her in the spooning position, but I felt something stir within me that made my heart beat twice as fast.
Claire's firm butt was pressed against my crotch. I tried backing up my lower body to leave some space between us, but she soon backed up to match me. Soon I had no more sleeping bag wiggle room to back up into, and I was stuck pressed against her butt.
As natural as it was for a virgin teen boy, all the blood in my body was being sent down to my d**k. There was no way I could just fall asleep then. My heart rate increased and my body felt hot. I was scared to wake Claire and embarrassed I was getting a b***r from cuddling with my sister.
My hardening p***s pressed up into my boxers and slotted itself right between Claire's butt cheeks. I was getting harder by the minute and my loose boxers were no help in containing my protruding member. It was beginning to stand up straight.
I was hoping Claire was asleep because I didn't know how I would be able to explain myself if she confronted me. I desperately tried to get rid of the b***r. I flexed my arm muscles, I thought of every unsexy thing imaginable, but nothing could alleviate the feeling of an ass pressed against my hard c**k.
My heart was pounding and with all of my struggling, Claire woke up. She shifted slightly, still holding my arm against her tummy when she froze. She must have noticed what was poking her.
She looked over her shoulder at me and I mouthed an "I'm sorry" to her. She shook her head and pushed me away, removing the contact our lower bodies had.
"Get rid of that. What the f**k," Claire scolded me, keeping her voice quiet to not wake our parents.
"I've been trying to," I responded.
"Well try harder, you perv."
"I'll turn around."
"Good.”
