*****
After fucking and making my twin nieces cum several times in the den and letting their older sister suck me to an intense cum, which she then shared with her sisters, I had gone upstairs to lie down on the bed and rest a bit. The niece's mother and my wife were due back tomorrow from a short "sister's" cruise. Mary my sister-in-law was supposed to have a mini vacation with her husband Bob but he got called away for a business trip. From what I could remember Bob was always off on business and missed a lot of growing up events with his daughters, my three nieces. Mary seemed to raise the girls by herself.
When Mary and my nieces visited us about very two years for about two weeks in the summer the girls couldn't get enough of me. It was if they were trying to take back with them enough male loving to fill the void left by their 'always busy' dad. Looking back I think it was during those vacations that the girls grew to love their 'Uncle Zach'.
The trips when the twins were fourteen and then sixteen were the ones I could have easily wound up in jail if I had wanted to be a dirt-bag and take advantage of them. Lucky my wife Beth and sister-in-law Mary ran interference to keep me from getting raped by those young and demanding girls. I took my life and the health of my dick into jeopardy every time I went into the pool with those three. I think their mom pushed her limits with me and Beth in the pool after the girls got out.
The last time the twins were here Shannon was eighteen. She met a boy in the neighborhood and asked to be allowed to go on a date – "pizza & movie." Since the boy could drive we told Shannon to be home before midnight or "else."
She just laughed, "Uncle Zach, really?"
"Don't test your Uncle," Aunt Beth told her. Shannon swirled her short skirt, laughed again and left for her date. Well of course we three adults were still up when Shannon came home past midnight. She had a full on case of 'kissy face'.
My wife Beth asked Shannon if she remembered the rule.
"Yes Aunt Beth I'm sorry the time just got away," Shannon mumbled with her head down. Winking at me Beth told her that we have rules in our house and she would have to be spanked for breaking them. "MOM," cried Shannon. Mary, my sister-in-law, told her that it was their house their rules.
I stood up and pulled Shannon over to the straight back chair and sat down. "Lay across my lap Shannon," I snapped at her.
"MOM," Shannon wined loudly. "DO IT," her mom said.
Shannon slid across my lap and did her best to keep her short skirt down.
"Beth, come hold her hands, Mary, lift her skirt and slip her panties down," I told the girls.
"MOM NO!" Shannon cried out.
It was too late. Mary flipped the skirt up to display pretty pink panties and slid them off Shannon's ass cheeks. Shannon must have had a good make out session with the boy because I could smell residual coochie honey as her panties went down.
"Shannon did we tell you the rules before you left?" I asked her.
"Yes Uncle Zach," she whimpered.
"Then you know why you are about to be spanked?"
"Yes Uncle Zach," she said starting to cry a bit.
"Well let's begin," I stated.
I then began a series of 'smack, Smack, SMACK' on Shannon's ass as each swat was a little stronger than the one before. Her cheeks turned pink then darker red as I kept up the disciple on her ass. I looked over at Mary and her eyes were glazed as in a trance. I thought to myself about what Mary was thinking just now – like would she want to be next? I swatted Shannon's ass for about five minutes until I saw Beth let go of her hands.
I winked at Beth and said, "Mary slide Shannon's panties all off and leave them on the floor here. Shannon, stand up and kiss your Mom and Aunt Beth good night."
When that was done I said, "Shannon come here and kiss me good night and thank me for disciplining you."
Shannon shyly kissed my cheek and said softly, "Thank you Uncle Zach, I am sorry I disobeyed."
She then went upstairs whimpering. I watched her up the stairs and saw her twin sisters looking at me with huge eyes and shocked faces. They helped their older sister into their bedroom and closed the door quietly. I looked down at my tan shorts and could clearly see a big wet spot where Shannon's coochie would have been. "Interesting," I thought...
So the feelings the nieces built up visiting us totally explains how willingly they offered themselves to my ownership and my pleasures on this trip once their mom and Aunt had left. Servicing three hot, hungry and young females over the last two days was wearing me out. I thought that tonight would be the last time with the twins and Shannon and I was already looking forward to my wife getting back home. She was womanly smart enough to know that her nieces would wear down my resistance and granted me permission to be as loving, caring and available to their needs as far as they wanted to take it. She told me to be kind and give them only good memories to take back with them.
I must have fallen asleep because I next felt six hands roaming over all parts of my body but my crotch seemed to be getting most of the attention.
"Uncle Zach, are you awake now," the twins whispered in harmony. I opened my eyes to six lovely naked breasts and six pointed nipples and three of the cutest naked pussies I have ever had the joy to see.
"Yes I am awake what is it you want," I asked them.
Bree, the most forward of the twins said flat out, "We want you to fuck us in the ass as you promised, then cum deep down our holes. This might be our last night alone with you and Marie and I want this feeling and memory of how much we love you." I looked to Marie and she nodded 'yes' shyly blushing deep red.
