Your mother emerges

"Bill, was that you?" Your mother, Gloria, emerges from the house, and freezes as she catches sight of the 15-foot Adonis that towers above her. She steps up to him, entranced, running a hand over the huge muscles that decorated his 6'7 legs. She realises she has to look up just to catch sight of his enormous balls. Your father grins, and his cock flexes impossibly downward, to look her in the eye.

"Bill..." she whispers, though her eyes are hazy with lust. With a wink, both from him and his cum slit, he lets go of the load he'd been holding in and showers your mother with a waterfall of milky pre-cum. With the new lubricant, his movements speed up, and the shlick of his strokes echoes through the house. Gloria simply stands, frozen, as the gentle rain pours down over her double D tits.

As the lust intensifies, the tension in the air building as your father inches closer and closer to release, you watch as his left hand keeps stroking the huge shaft, while his right picks up your mother, encompassing her head, neck and shoulders all in his gigantic fist, and presses her mouth against the head of his cock. The slit is bigger than her entire mouth, and encompasses her lips within the fleshy urethra. Still, she does her best to suck him off, and her tongue swirls around the inside of the tube. Bill groans, the new and pleasurable sensations sending tremors through his titanic form. You know he has reached orgasmic heights as he throws his head back and roars at the sky.

But, just moments before the tide of cum comes rushing down his dick, you whisper these words: "I wish my dad's cum improved everything it touched."

You click your fingers, and the spew of hot white seed spills into your mother's mouth. She drinks it down readily, and impossibly manages to not let a single drop escape. Once Bill empties his prodigious balls, Gloria's stomach is bloated so far it stuck out over a foot in front of her. Gently, she is placed back down on the ground. Her rotund gut pushes her down, too heavy to even sit up. She groans in happiness.

Then, right before your eyes, you watch as her gut begins to shrink.
