Caught in the Storm: A Night of Unexpected Intimacy and Playful Sibling Rivalry

The crash of thunder jolted me awake, my heart pounding in my chest. I lay there, blinking in the darkness, as another bolt of lightning illuminated my room. I groaned and rolled over, trying to fall back asleep.

But then I heard it - a blood-curdling scream that could only come from one person.

My little sister, Emily.

I sat up in bed, my heart racing as I listened to the sound of her footsteps pounding down the hallway. A moment later, she burst into my room, her eyes wide with fear.

"Emily, what's wrong?" I asked, my voice thick with sleep.

She didn't answer. Instead, she climbed into bed with me, burrowing under the covers and seeking comfort in my warmth. I lay back down, feeling the warmth of her body and the way she was wiggling to get closer to me.

It was then that I became aware of something else - the feeling of my semi-hard cock pressed against her.

I froze, my mind racing. What the hell was happening? I tried to subtly shift my position, but Emily only wiggled closer, seemingly unaware of the situation.

The feeling was intense, and I tried to think of anything else to stop myself from getting too aroused. But it was no use. I could feel myself getting harder and harder, my mind spinning with thoughts of Emily's soft, warm body pressed against mine.

I considered waking her up and making her go back to her own bed, but I didn't have the heart to do it. The tension built, and I tried to think of a way to discreetly deal with the situation.

But before I could do anything, I felt a surge of pleasure and came hard, the wetness spreading between us.

I lay there, stunned and embarrassed, as Emily sleepily murmured, "Thanks, big brother. That felt nice."

I couldn't believe what had just happened. I had just come in my pants while my little sister was sleeping next to me. I was a mess, both physically and emotionally.

I decided to clean up and pretend like nothing had happened in the morning. I lay there, wide awake, as the thunderstorm raged on outside.

It was going to be a long night.
