Maybe

I tossed and turned in my bed, unable to go asleep. Thinking about seeing my sister naked earlier in the evening and knowing she was probably naked just on the other side of the wall got me all hard again. I reached down and grabbed my swelling cock with one hand and started stroking it with images of my naked sister running through my head.

I moaned lightly as my rod responded to my touch, picturing my sister on all fours in front of me with me on my knees lining up my hard shaft, ready to plunge it into her wet warm pussy. I could hear her moaning softly as she waited for me to penetrate her.

Suddenly I paused and lay still, holding my hard cock but not stroking it. I listened carefully. Those moans were not just in my imagination. They were coming from the other side of the wall! The sounds were very faint but it was definitely moaning. Was she in her room, thinking about the same thing I was thinking about? I wouldn’t have been surprised. After all, it had gotten pretty hot between us at the party.

Then it seemed like the moaning had stopped. I waited and listened to be sure. Then I heard a slight creaking noise like a door opening. Then I saw a low light from the hallway as my door slowly opened. In the low light I could see a figure step into my room and close the door.

“David?” I heard this very low whisper, very close to my bed. “Are you awake, David?” It was my sister’s voice.

The thought that she was standing naked by my bed brought my cock back to full hardness. But I wasn’t sure what I should do.
