They join together

Just when I think the sisters' hands are about to meet on my cock with disasterous consequences. Meg takes her hand off my thigh, and finds my hand with hers and guides it under the blanket towards her crotch. This is out of character for my wife, she's not normally so direct about her needs. As soon as she places my hand on top of her panty covered slit I realize why, she is practically dripping wet.

I rub lightly up and down her slit. At this point Meg lets out a barely audible sigh feeling that her dripping desire will soon be satisfied. But I freeze in place for at that moment Samantha's nearly forgotten hand has found it's way to my cock. Her hand is rubbing up and down my length through my shorts slowly squeezing and releasing me. This is clearly not an innocent mistake now.

Megan does not seem to appreciate the pause in my action, she uses her hand which is still resting over mine to slide the fabric of her shorts and panties to the side. Just as my fingers come into contact with the naked flesh of my wife's hot lips, her sister Sam snakes her hand inside my shorts and pulls out my throbbing hard cock.

Stunned by all the action under the blanket I'm too slow to react for Meg's liking, so she guides two of my fingers into her sloppy wet gash. Instinct takes over at this point and I begin to work my fingers in and out of my wife's pussy. While at the same time Sam is slowly working her hand up and down my length, exploring my shaft.

If this wasn't so potentially disastrous this would be amazing.
