When my brother died I felt obligated to take care of his wife and daughter. I was very close to them even before the accident. It was very tragic and in order to calm them down I did what I could to keep their minds off it. I would take them shopping, or out to eat, or to a movie, or mini golf, whatever I could think of. We got very close. When his wife died several years later in a car accident, in her will, she said she wanted me to raise their daughter, Sarah. I had never been married or had any kids, so I didn't know much about raising kids. However, Sarah was fourteen years old, more than 3/4 of the way grown up already, so I figured I didn't have to work too hard.

As the months went by, Sarah and I got to be closer and closer. Also, Sarah became more mature, her breasts getting bigger, but I only looked at her as a father would. I didn't notice it at the time, but Sarah often stared at me from across the dinner table while we were eating.

One day it was raining, so we were playing a board game inside. We were playing "Scattergories," the game where you roll the die to pick a letter and try to find as many words in the specific categories as you can before the timer goes off.

As we were waiting for the timer, writing down our words, I noticed Sarah staring at me again. I dismissed it. Suddenly, she got a weird look on her face and started squirming in her chair.

I looked up and asked, "Are you alright?"

I don't know, I feel... squishy," she answered.

"What?" I wondered what she was talking about.

"I don't know. I feel squishy... down here," she indicated her crotch by putting her hand there. I noticed her shorts were damp.

She was wearing pink hot pants, and a white tank top. She put her hand down her pants with an inquisitive expression on her face.

I could tell when she reached her clit, because her eyes got really wide, then shut and she made a quick intake of breath. She continued to wiggle her fingers and rub her pussy under her shorts, oblivious to me.

The timer stopped and she appeared not to hear it.

I suddenly remembered that I was her legal guardian and I should probably tell her that she shouldn't be masturbating, but then I realized I didn't care if she did. I had no religious reasons for her to stop. I thought it was a great thing to do, I did it all the time. Also, I wanted to watch her, it was a great show. I kept my mouth shut.

My cock grew in my pants, but I ignored it.

Sarah began moaning. She got louder and louder and faster and faster. Everything in the room was non-existent to her.

She came with a short yell, then collapsed on the chair with her hand in her pants.

After a couple of minutes she opened her eyes and looked at me. "Uncle Tom, what happened?" she asked.

"Well, um," I was surprised by that question. "I guess you just masturbated."

"Oh, I interrupted the game, I'm sorry," she interrupted me.

We finished the game and then went to our rooms and went to sleep without discussing it any further.

The next day we ate breakfast and Sarah went to school and I went to work and she didn't bring up the last night, so neither did I.

All day all I could think of was Sarah. Until that night, I had never thought about her sexually, but now I was realizing she was a very attractive girl. Her hair was dark brown, and short. Her tits were small, b-cup, but that's the way I like them. She had a petite frame. Everything about her was perfect, exactly the way I love women. The picture of her screaming with pleasure in my head distracted me all day.

When I got home, Sarah wasn't there yet. I took the trash out back and while I was outside, I heard the front door close. That would be Sarah. I went inside and went upstairs to her room. I leaned on the doorpost and looked at her.

"Oh, Uncle Tom," she said, "I was at school and I was talking with my friend Jennifer about what I did yesterday and she said that she does it too! You know what else she said? She said that it's even better if you're doing it with somebody else! So I asked her, what do you mean? And she said that a guy can put his penis in a girl's vagina and it feels ten times better, so Uncle Tom, can we do that, pleeese?"

I was completely stunned by this question. Here I was thinking about doing her all day and now she was practically begging me to fuck her. And to add to that, I knew I wasn't supposed to do it. I was very confused, so all I could say was, "I'll think about it" or something, and then I left to make dinner.

I made meat loaf or something, I don't really remember, and while we were eating, she kept looking at me inquisitively, as if to say "please?"

I kept quiet during dinner.

After dinner I sat down in front of the TV to watch some sports news like I always do. After a while Sarah came in and sat on the chair opposite the sofa, where I was.

She was wearing jeans, a t-shirt, and a button-up shirt loose, like the teenagers like to wear so much these days.

It was too much for me. "Ok," I said, "What do you want to do?" I turned off the TV and put the whole thing in her hands.

"Yay!" she said.First, she stood up and took off her shirt. Then she took off her t-shirt. She had a pink sport bra, one I had bought her last month. Then she unbuckled her belt and slid out of her jeans. She sat down next to me on the couch with nothing on but a pink sport bra and white cotton panties.

She took off my tie and unbuttoned my shirt. She rubbed by chest hair between her fingers. This was nothing new, chest hair, she had seen me at the beach.

She took off my jacket, then my shirt and unbuckled my belt. She pulled down my pants and took them off along with my shoes and socks. She rubbed my erection through my boxers.

She pulled off her bra and her b-cup breasts bounced in my face. I licked the nipple closest to me and she sighed with pleasure. I cupped both breasts in my hands and kissed her mouth sensually.

She backed away and pulled off her panties. She dangled them in my face, the smell from her crotch filled my nostrils.

I fell on my face on her pussy and ate her with delight.

"Oh, my God!" she exclaimed.

When I could tell she was adequately aroused, I took off my boxers and inserted my cock. I noticed it didn't go in all the way.

"This may hurt a little," I explained.

"I know, I went to Health class, Uncle Tom," she smiled.

I smiled and shoved as hard as I could.

"Ahh!" Sarah had a short outburst then kept quiet.

With every thrust I could tell she was enjoying it more and more.

She got wetter and wetter. When she came she screamed with a smile on her face.

As her vagina contracted around my cock, the feeling was incredible. I shot my load deep inside her.

We both collapsed in each other's arms. We spooned as we slept for a few minutes. Then Sarah went upstairs to do her homework. That night I fell asleep listening to Sarah's cries of pleasure as she masturbated herself to sleep.
