"Oh come on Sis," my aunt replied. "You know you've always wanted to do the same. How could you not? Look at this cock!"

"Because I'm his MOTHER!" she replied, indignantly.

My aunt snorted in derision at her response, never slowing down the pace at which she continued to jerk my straining prick.

"Right," she replied. "And I suppose it's totally normal for a mother to finger her dripping wet cunt to her son getting his cock jerked off."

My mother had no response for that, but continued to plunge two fingers in and out of her sopping pussy. She licked her lips as she watched my aunt's fist fly over my spit-slickened rod.

"I'm close Mom!" I announced, desperate to blow my load for her. She moaned at my words.

"Do you hear that? Your son is about to cum for you. Now quit lying to yourself and get over here and eat his cum! You know you want to."

"Here it comes! I can't hold back any more!" I cried.

"Hurry! Put it in your fucking mouth! Swallow it!"

The last thing I saw as my vision went white was my mom springing up and lunging towards my crotch faster than I thought possible of her.

I exploded in my aunt's hand, which was immediately replaced by the most exquisite velvety-soft feeling I had ever experienced. The part of my brain that wasn't being completely overtaken by the overwhelming pleasure of the moment knew that I was now cumming in my own mother's mouth.

Somehow, that fact alone intensified the white-hot pleasure coursing through me into an experience I knew I would never forget.
