Helping hand...and mouth (2)

Zach showed up in a tight pair of jeans and equally tight old t-shirt at our door, ready to help me. He no doubt wore them to get the attention of both my wife and daughter. The thought of him showing off for the girls in front of me, gave me a thrill which got the blood flowing to my cock.

We got to work in the study tearing the sheetrock down. Even though it was a hot day out I had turned off the AC so that the dust wouldn't be sucked back into the system. Instead I threw open the window to let what little breeze there was, try to keep us cool.

After about a half hour I heard the screen door open and shut and voices coming out on from deck. As I looked out I saw my wife and daughter walking out in the smallest bikinis I'd ever seen them wear. They were matching styles, string bikini bottoms and strapless tops. The only difference was that Brianna wore pink while Stacy's was black.

I stopped what I was doing and said to Zach. "Looks like we get a show while we work" as first Stacy helped Brianna with suntanning lotion then Brianna returned the favor for her mother. I hadn't looked at Zach since the two appeared so as I turned towards him I was shocked to see him gripping the very hard and quite large outline of his cock through his jeans.
He continued to stare and mumbled "Damn" as his simple reply.

My cock filled out almost instantly at the lewd scene being acted out by the three of them. Without thinking much about it I pulled my shirt off and said "Well beteeen no air conditioning and those two, it's too hot for a shirt" . Again he just mumbled a reply "Yeah" as he absent mindely joined me by pulling his shirt over his head, still taking in the girls shameless display.

Even at 18, his nicely muscled and toned chest was basically hairless. I took is how dark his ripples looked against tanless white pecs. His chest looked so soft and smooth that I shocked myself with a urge to caress him.

I finally got the us back to work, to some degree but both of us would still take whatever opportunity there was to leer out the window at the girls. Sheetrock down we began framing up the new wall. As I started to throw up an end stud, I asked Zach to grab the level. He turned to get it as it stood up next to the window. He stopped in his tracks and said "Fuck...look at this" I walked up next to him and looked.outsude. To no surprise to me, both girls were laying on their bellies topless.

I looked over at Zach to see him not only grab his crotch but move his hand up along its length. I patted him on the shoulder and said that the two teased me like this all the time. I left my hand on his shoulder as I called out to them. "Now how exactly are we supposed to get anything done with you two sexy ladies showing off like that?" I heard both of them giggle, then my wife turned towards us, briefly showing us the full side of her breast and say "Well at least we aren't completely naked" which I replied "Well don't let us stop you" My wife laid back down on her belly, but then reached behind her, untied the strings of her bottom and pulled it out from underneath her. She turned and said something to Brianna, but she just laughed and shook her head.

I squeezed Zach's shoulder as he groaned at the naked vision in front of him "I can't count how many times I've stood right where you are, and beat off because of them" I said quietly.. With my other hand I unbuttoned and unzipped my shorts letting them drop to my ankles. I pulled my underwear free and stepped out of both. He glanced over at me, naked and hard,and followed suit. His pants fell down his muscular legs to the floor. Surprisingly he wore no underwear so his youthful cock sprung upwards as a small stream of precum dangled from his circumcised cock.

I lost all self control and dropped down to my knees in front of him.The last image of my wife before before I dropped below the window, was of her splitting her legs open so that her beautiful shaven pussy was on full display for us.

As I gripped the base of his stiff shaft I looked up at him. His eyes were still glued to the girls. I pointed his perfectly shaped cock towards my mouth, and although he wasn't as thick or as long as me, his 6.5" length sltill filled mouth. i felt his hand grasp my head as he began fucking my mouth in earnest. Soon I heard him quietly say. "Oh Stacy...oh Stacy...I'm gonna cum"

True to his word, my mouth was soon full of teenage spunk, which, although salty, tasted really good, much better than my own in fact. I stood up, my lips still wet from his nectar, grabbed his face in my hands and passionately kissed him. .

I turned to look outside towards the girls.. My wife was still stretched out nude on her belly, but my daughter had fastened her top back on and flipped onto her back. In doing so, she had just watched me passionately kiss Zach. She looked both mad and turned on. All I could do was shrug my shoulders , smile and think tto myself "Sorry baby, daddy got him first. There's always next time for you"
