This story happened when my Dad went to Vietnam shortly after I turned 18. His younger sister had flown in to see him off, unknown to the rest of the family. As I came home from school, she threw a pillow at me and ran into the family room. I grabbed the pillow and gave chase. As I caught up to her, my aunt slipped and fell to the floor. I fell on top of her and we rolled around, each trying to get the upper hand and hit the other with the pillow. I ended up on top of Aunt Ida, and as I looked down at her I could feel myself getting hard. I quickly jumped up, embarrassed, and ran to my room.
Later, as I calmed down, I heard the front door open and my parents came back home from last minute shopping for things Dad would need overseas. I went back out front, but could not look at my aunt. We made it through dinner, and sat and talked about the next day's ride to the airport to see Dad off. I excused myself and went to my room, still unable to look at my aunt.
After everyone went to bed, I lay there thinking about what had happened, when I heard my door open. I looked up, and my aunt was standing in the doorway with her hand to her lips telling me to be quiet. She came across the room, and sat at the edge of my bed. She asked if she had done something to make me mad, as she had sensed my unease around her. I told her it wasn't her, but me that I was mad with. She looked down and asked me why. I said "I didn't mean for that to happen."
She said "Didn't mean for what to happen?"
I couldn't believe my aunt hadn't felt my cock pressing against her thigh, but was too ashamed to tell her. Aunt Ida looked down and said " Why won't you tell me what happened between us?" I finally told her that I had gotten aroused looking down on her when we were wrestling, and had to run away before she yelled at me. She looked at me and told me she had felt my erection and was pleased that I had found her attractive, since she was so much older than I was. I told her 12 years difference didn't make her old. At that, she smiled and reached under my covers to find that I had an erection again. She started to give me a hand job, and I barely lasted five strokes before I came all over her hand. She smiled as she brought her hand to her mouth and licked it clean. I reached up and gave her a full-mouthed kiss, tasting my own cum on her lips.
I then got bolder and reached for her small breasts and found her nipples hard and pointy. Aunt Ida put her hands over mine and told me to slow down and be more gentle. I told her I was sorry I hurt her, but it was my first time with a girl and I was so eager I rushed too quickly. My aunt beamed, and said she would be glad to teach me how to please a woman. She instructed me to slowly undress her, and as I did I kissed each part of her body I uncovered. She began to squirm on the edge of the bed, and I moved over and pulled her down beside me. We started a long, slow kiss that moved from her lips, down her neck and around to her earlobe. She giggled and tried to squirm away, but I pulled her tighter and licked her ear. She moaned, and I moved down her chest, rolling her nipples in my palms as she shrugged her night shirt off her shoulders and down her back. I sat back and looked at her, and she told me to keep going as I was doing good so far. I leaned in and kissed her nipple, and as Ida moaned again I took more of her into my mouth. After what seemed like hours, but was only a few minutes, Ida pulled my head away and told me I had to quit before she came. I leaned back in and alternated right and left until Ida came, and came hard. When she finally settled down, she looked at me and said it had been years since she had experienced a nipple orgasm. I marked that in the back of my mind as something to come back to if I ever got the chance with my aunt again.
