The rest of the afternoon, Missy followed me around like a puppy dog, wanting to get close or next to me wherever I went. Not that I minded as my cock was now definitely ruling my mind.
We had finished supper and the night air was cooling down and a full moon would make it light outside almost all night. The boys had all taken showers and were getting ready for bed as Missy took her shower. When she came out of the shower, I noticed her in a different light for the first time. She was wearing a short cotton nightie that just barely covered her little panties. Her dark nipples pushed out against the soft fabric and she noticed me watching her and smiled to herself.
Jacob always wants me to read a book to him as he goes to sleep and tonight was no exception. Justin had jumped up into the top bunk and was almost instantly asleep. Missy had crawled into the bunk opposite Jacob and was quietly lying there as I read the book. It wasn't long and I could tell that Jacob was also asleep. I got up to leave and a hand reached out and rubbed my leg, it was Missy. I reached over turned the light off and leaned down close to her to see what she wanted. She didn't have to say a word; she just lifted the bed sheet and beckoned me to crawl in with her. My heart started pounding again as I anticipated what I was about to do.
I crawled in beside her and could feel the warm soft flesh lying next to me. I just lay there waiting to see what would happen next. Missy reached over, took my hand and lifted the top edge of her panties, placing my hand down between her legs. Then for the first time she took her hand reached across and placed it directly on my cock, which was now at full attention to what was happening. She was new at this and didn't quite know what to do, so I helped her feel my cock and than she felt my soft balls with her fingers, gently massaging them. I knew that things were going to progress further and didn't want it to happen there in the bunkroom. So I gently kissed Missy on the lips and told her I was going upstairs to bed and she could follow if she wanted.
I left her bed and went upstairs to mine, trying to rationalize what might happen next. She was definitely of age so there wasn't any legal problems with what I was doing; it was that I had always thought of Missy as a boy and not a girl. Boy was I wrong on that one. Anyway as I lay there she must of known what she wanted, because I could hear the stairs creak as she made her way up to my bed. I lifted the sheets for her and she crawled in next to me snuggling up close. The moon was bright and lit up the room so you didn't need any lights to see clearly. I looked into her face and asked her if this was what she wanted? She nodded, smiled and said make me feel good again.
I leaned over kissed her on the neck and then kissed her on the mouth and let my tongue explore her sweet young mouth. With my hand, I slid down between her thighs and found her panties waiting for me. The surface of her cotton panties was already getting wet in anticipation of things to come. As we kissed I could feel her hand starting to explore on her own, seeking out my cock and rubbing it through my pajamas.
