My older sister has me over for dinner quite often. She's a young widow and I rave about her cooking (which is good) and this does the trick for future invites. I have one problem. Her daughter, my niece, Nancy, who was only 14 when this began, is an unusual little bird. Whenever we were left alone she reached under her skirt and started masturbating right in front of me. She really went at it and often I could hear the slurping sound from her wetness.

Naturally, I'm only human and couldn't take continuous teasing like that. She's not a showstopper but a cute little thing, flat chest, curly light brown hair and lovely legs and butt. I thought she'd stop after a while of my ignoring her but she continued. Mostly, she'd move closer to me and the pussy slurping was louder as she fingered herself and rapidly rubbed her little clittie. Once in a while we almost got caught. I was not as frightened since I did nothing but ignore her.

In time, I began to get rock hard erections. While I don't possess a whale dick, if I am erect there is no way not to notice. I've tried very loose fitting trousers and stopped wearing Levis. It did not work. Then, the thought occurred to me to tease her back. When she would begin, I would pull out my erection and just sit there. It was so hard I could hear her breath knock out of her. She stopped for a time, then really wanked hard. Her little pussy took a hard pounding. I kept pulling my cock out to tease her back and, undaunted, she just continued.

Asking my sister at some point "How is Nancy? Is she o.k? How is she doing in school," I fully expected to hear that she had problems but apparently she is a leading student, then, a High School Freshman. I guessed that she was then just overloaded with female hormones amidst her puberty. Seeing my hard cock did not have the effect I was after. I do love the kid and my sister as well but cannot expose her behavior, especially after having exposed myself, something that I had not thought about before doing it, in desperation.

She took our scenario vocal and began to plea and beg for fucking. She told me how badly she needed it and that I would be kind to her by fucking her. She showed me what she does with a cucumber on her phone and I told her to delete that file, that it was dangerous to have it. She countered, saying that her face is not on the video. She pushed a rather large cuke up her vagina and later, totally up her ass until it disappeared, then showed me how she pushes it out again. She was so far out with all of it that I started thinking of seeing a therapist. Pehaps her being fatherless played a hand.


Now, I was close to giving in. I kept telling myself that I was 13 years her senior and an adult, fighting off thoughts of jumping on her like a madman.

She asked, "Then let me touch it, just touch it." I said that would lead to more and she said it wouldn't but we both knew that it would. The other problem was that she would keep masturbating while negotiating with me, making it harder for me, if you'll pardon the pun. Finally, she promised a compromise deal and I was starting to get blue balls from the frustration brought on by the little witch. I would let her touch it and suck on it and she would try to wait until she was 18, at which time I told her I would absolutely fuck her brains right out if she still wanted it.

We waited for a time when my sis, her mum, went out to pick up some stew makings and Nancy just about went crazy. She quickly grabbed my steel shaft cock and went right down on it, driving it in and out of her mouth, so fast that it took under one minute for me to blow my load in her mouth, I almost shouted, pulsating about nine to ten spurts. She hungrily swallowed and lapped up every drop of my cum. My legs felt like soft rubber and I was dying for more but the thought of bringing conflict to my beloved sister dampened my lust. Nancy stopped masturbating in front of me every chance, keeping her promise.

What the little vixen did next, however, still fills me with some guilt. Not long after that long, sought after, brief blow job, I received a late night call on the phone. It was Nancy. She said, in her wee, teen voice, "Hi lover, guess what I am wearing?" At first puzzled, and searching for a decent answer, I asked, "What, Nancy." She said, my two fingers, and started to laugh. We now have phone sex at night almost daily. In two years, if she still wants it, I will have to give it to her. I see no way out. Hopefully, we won't injure each other too badly at first.
