My wife Kim and I have been married for fifteen years, we are still in love, but until recently our sex life had dwindled off somewhat due to a drop in my libido, despite this I had never even thought about sleeping around, but about 3 months ago something happened to change all that when Sue, Kim's 18 year old niece moved in to live with us.
Sue came to us because her parents felt she was getting out of control and thought maybe a change of living arrangements might help her. Personally I felt she was just rebelling because they had tried too hard to push her to conform to their own strict puritanical ways. And because of this they had watched their blond, blue eyed, church going, piano playing angel, turn herself into a punk rocker with jet black cropped spiky hair, colored contacts to make her eyes green, piercing's in her nose, eyebrow, and belly button. She was also into heavy metal music in a big way.
Sue recently had a bit of a growth spurt and was up to about 5' 6' her breasts were about a B' cup, which was just right for her build. She usually walked around the house in short leather skirts and skimpy tops with spaghetti straps and no bra. Since we keep the house fairly cool I was often treated to the gorgeous sight of her protruding nipples. Sometimes she would tease me by deliberately sitting opposite me with her legs apart without any panties on, so that I could see her lovely trimmed pussy with it's protruding lips, which never failed to make my cock grow so hard, I would usually have to go to the bathroom and jerk off to make it go down. Also when lying in bed I only had to think of her gorgeous body and what I would like to do to it, for me to get a terrific hard on which would usually lead to a very steamy session of lovemaking with Kim, who was very pleased with my renewed passion in the bedroom.
One day a few weeks ago after Kim had left to go shopping, I went to the kitchen and Sue was sitting at the table drinking juice and eating some cereal. I poured a cup of coffee and sat down. "Morning Sue" I said opening my paper to the sports page.
"Hi! Unc;" she said not looking up from her book.
"You were late last night, I said, "we didn't hear you come in.
"She looked up and smiled "I wasn't that late Uncle Bob, you probably didn't hear me because you two were in the middle of a very hot sex session by the sound of it" winking at me as I looked up.
"Oh!" I said, a little embarrassed, because my wife does tend to get very vocal when we're making love.
She just chuckled "Don't be embarrassed Unc; it's nice that you two guys have such a good sex life. I only wish my parents still screwed, instead of acting as if sex was dirty and sinful, maybe then they would lighten up on me a bit" I looked at her and thought she was probably right her parents were so uptight and righteous, I'd bet they hadn't had sex in months if not years.
"Well Sue I suppose we are a pretty laid back household here compared to what you're used to" I said.
"I know" she said laughing as she put her book down "I have to listen to you two when you get laid back, but I still really love being here anyway"
"We love having you here too Sweetheart so you can stay for as long as you want, and we will try to be a bit quieter in future so as not to embarrass you" I said.
"Don't bother to keep quiet on my account just carry on doing it as you usually do, I'm not embarrassed, in fact I hope you won't be angry or shocked with me, but I often pleasure myself while listening to you both'' she said quite seriously as she got up to put her dish in the sink.
"I see" I said as she walked over and sat beside me "and just what do you think about when you pleasure yourself?
"She said "Well if you really want the truth Uncle Bob I fantasise that your cock is inside me instead of inside Aunt Kim's" I swallowed nervously not knowing what to say. "You see I think about you every time I stick my fingers in my pussy wishing it was your cock instead?"
