Taking a step back I had to admire the twin's stretched asses and their pussy lips popping out from between their thighs. I walked into my bathroom and returned with my hair brush. It has a nice thick bone handle and my wife Beth had bought it for that very reason. I held the brush and began a series of taps and light smacks on the cheeks of each twin's ass. They moaned after each of the series would end with a hardest swat. I turned the brush over and stood behind Marie first. I ran the bone handle from the bottom of her pussy near her clit up her lips and over her rosebud and through her ass cheeks.
Her head lifted off her sister and she moaned, "Ooh god, yes Uncle Zach, please more of that."
I reversed the trail and lingered over her anus and she pushed up trying to capture the bone. I swatted her ass with my hand then lowered the handle to slide easily between her pussy lips and placed it at the base to rub over her clit which was now growing and popping out from between her pussy lips. I let the bone slip up into her pussy and stroked her with it for a minute or so. She began to build up a sweat down the crook of her back. I slid it out to her whimpers and slowly slid it up and placed it directly against her anus. This time I slowly slid it past her anal ring and deep down until the bristles where touching her ass cheeks.
"Do you like that baby," I asked her as I did mini up and down strokes with the handle in her ass.
She moaned, "Oh god, yes Uncle Zach, I love that but can I please have the real thing soon."
For her answer I slid the handle out and moved behind her sister Bree who was really into her sister's pussy. Her own pussy honey was coating her pussy lips and running down her legs. I squatted down and pulled her ass cheeks apart. I then ran my tongue over her clit, up her pussy lips then formed it into a point and shoved it against her asshole. Bree snapped her head back so I grabbed her hair and pulled back. She arched her back so with the other hand I slid the brush handle deep into her pussy and started fucking her with it. Suddenly she came all over the brush and her juice poured down her legs.
I let go of her hair, pulled the brush out of her pussy and centering it directly on her anus I slipped it fully down her ass chute. I slapped her ass with my hand and left the brush imbedded in her ass and moved back behind Marie. I then watched the twins bring Shannon to a thrashing series of orgasms that I am sure soaked the bed covers. I took my cock in my hand and slid it between Marie's pussy lips then down into her pussy till it was balls deep.
"Not there Uncle Zach," I heard Marie whisper, "Do it where you promised."
So being sure my cock was coated with her pussy honey I pulled out and placed the head at her anal door and started to slowly push down. I felt Marie push up from her feet so she made the mushroom head pop in past her anal ring. She started to breath heavy. Since they had made Shannon cum multiple times the twins now rested their heads sideways on her thighs and locked eyes to watch each other react to what was happening. I slid my fingers through Marie's pussy to get more honey and coated the shaft of my cock. Once it was nice and wet, I slowly started sliding more of my meat into Marie's ass. When she raised her head I knew to stop to let her get adjusted to how much cock she had taken so far. When she lowered her head again I slid another inch or so into her ass. I saw her reach a hand to her sister which she squeezed until my balls lay against her ass cheeks.
"Oh my god Uncle Zach I feel so filled and so hot and I want more of this from you. This will be only your special place all my life," she moaned and whimpered. She gasped as I slowly slid back to the mushroom head and hissed between her teeth when I slowly slide all the way back in. I did that for a few minutes increasing the quickness of the pull back and slide back in.
I was getting Marie close to coming but slowly slid all the way out. Marie quickly reached back with her arm and tried to hold me in. I slapped her ass and told her I had to break in her sister now. To leave her with some feeling in her ass I pulled the bush handle out of Bree and slid it into Marie's ass. "If you want to make yourself cum Marie I give you permission to rub your cunt." When I said "cunt" I slapped her pussy lips then rubbed her clit between my fingers. Marie shook like she was having a body earthquake.
I moved behind Bree and ran my rock hard cock between her pussy lips but went straight for her anus and slid the head past her backdoor ring. The large mushroom head invaded her anus and popped fully in stretching her open for the rest that was to follow. Bree started an up and down and a little side to side dance with her ass as I slowly slide my cock shaft deeper down her ass. She was humming and doing small little cursing sounds as she was being impaled. I soon was getting my balls massaged by her ass cheeks and she continued her little samba on my cock. It seems I did not have to be delicate with Bree's ass so I went at her a little stronger then Marie's ass. I was quickly sliding out to the head then back fully down to the base and it got to the point where I was pounding her fairly well.
I slid my cock out of Bree but quickly slid two fingers into her ass and kept them in deep while I moved behind Marie again. She slid her two arms backwards and pulled her ass cheeks wide apart.
"Again, harder and longer, PLEASE Uncle Zach I am very close," she pleaded.
I slid the brush handle out of her ass and up her pussy then set my cock at her back door and slid all the way in on one stroke. Her head snapped up and she started crying in pleasure so I picked up the pace and stroked back and forth ever faster until I felt her ass chute grip me hard and start to pulse. She screamed herself into a very intense orgasm and sprayed honey out of her pussy to soak my legs.
My fingers moving inside Bree's ass was bringing her close to orgasm so I gave up the ghost and shot my first cum load down Marie's ass. I quickly slid my cock out and pulling my fingers out, rammed my hard thick cock down Bree's ass and shot my second load into her ass.
I pulled out and quickly and slid full balls deep into Marie and shot my third load. Since Marie was finishing her orgasm, I slid my cock out and slid back inside Bree's ass and shot the last few ropes in her ass as I pounded deep down her ass. I reached over and slid two fingers down Marie's ass and six packed her pussy and clit with my thumb. That brought Marie off on two or three new mini orgasms until she started sobbing and her legs turned to jelly and could barely hold her weight.
I rested my cock deep down Bree's ass and brought some fingers down and attacked her clit until she had a few mini orgasm and collapsed her weight on the bed. I slid my softening cock out of Bree and moved around to the side of the bed. I motioned Shannon to get in the middle of the bed and under the covers. I then moved an exhausted Marie to the right side of the bed and her sister Bree to the left side of the bed. I started towards the bathroom when Shannon asked me where I was going. I told her to clean up before coming to bed. She wagged her head to indicate 'no' and motioned for me to get in the middle of the bed.
My wife and I sleep on a king size bed so there was plenty of room. When I got in bed Shannon slid down my body and took my soft cock fully in her mouth and cleaned it of the cum and pussy juice. She licked my thighs and balls of the same juices until she was satisfied I was fully clean. I could swear she was purring while she went about her work. When she was done she slid up to rest her head on my chest.
Shannon then said in the dreamiest of voices, "I love you Uncle Zach and I always will."
Bree then said, "I love you Uncle Zach and I always will," followed by Marie sobbing out, "I love you Uncle Zach and I always will."
"Good night my princesses we will see what tomorrow brings, but for tonight fall asleep knowing you are deeply loved by your Uncle Zach who will do all in his will power to give you a good start at life. Go to sleep and dream sweet dreams in the arms of the one you love," I cooed to them. I listened as each niece softly cried herself to sleep. It was only after all three were sweetly asleep did I doze off and dream of queens and princesses and a castle home.
