On her plump belly (in her belly button)

Tumbling through the air Erik flailed around wildly unable to control his momentum. His vision was a blur falling for a full second until...*smack. Upon his landing he was surprised to have been completely unscathed. Pushing off of what he landed on his hands sunk in a bit to the surface. Regaining his senses Erik looked around to see that he was surrounded by a cavern of his mother's skin. He stood up and tried to look over the mounds of Laura's curves finding that he had landed directly into her deep belly button. Erik turned his head towards Laura's upper body, barely able to see over her round belly he saw that her eyes were closed taking in the soothing warmth of her bath. Laura's huge bare breasts sagged slightly off of her chest. However, her nipples stood straight up and were becoming harder as she sighed in relaxation. Erik began to get hard at the idea of burring his face...no his whole body into her cleavage. Knowing she was unaware of his presence Erik began to stroke his cock.

"Fuck, Mom has nice big tits...I shouldn't be doing this but she's totally out." Erik thought to himself. "I just want to crawl up to her and..."

Erik was cut off by a shadow slowly covering his body continuing up Laura's plump belly. Further and further the shadow grew nearly up to the bottom of her huge exposed breasts. Curiously Erik turned around to see what could be casting such a long shadow. Coming into vision was a large dark purple mass slowly coming towards him. Scared by the incoming object Erik dropped his weight back into his Mother's deep belly button. The object was still heading towards him now covering the entire entrance to Laura's belly button. He was now trapped under a massive purple nearly twice his height across. Contained in his Mother's fleshy cavern Erik could hear Laura moaning and her stomach grumbling. Erik tried to push on the object trapping him. The surface was much...much stiffer than his mother's skin and covered in a slick fluid.

"This feels like lotion...WHAT THE HELL IS THIS THING?" Erik thought, beginning to feel a bit claustrophobic.

Erik began to push harder on the wall of slick flesh. Strangely he could feel a pulse. Then a different more sticky fluid started to cover his hands and fill Laura's belly button. Suddenly the object forcefully; but briefly, thrust into Erik's body. He was pushed onto his butt as the object's weight lifted off of him...only to come back down harder, crushing his body into his mother's soft belly. Several times he was smothered by this object while covering him in the musky, but sweet liquid. Erik cleared the liquid from his eyes as the object finally lifted it's strangle hold from his cavern. Regaining his vision the massive wad slowly pulled away.

"Ugh...what the fuck? What the...FFFFFFFFuck is this shit?" Erik thought throwing the liquid off of his hands. He noticed his mother's belly button was filled up to his rib cage with this liquid.

Erik looked forward at what the thing that had been crushing him. Slowly the dark purple mass moved away from him. He began to see that it was covered in veins; the rest of the huge long object was a deep dark skin tone. Eventually he came to see that the object looked like a huge black cock.

"Damn Mom that dildo is huge...and so real looking" Erik thought. "Damn it just keeps getting bigger...wait she's holding it backwards, right?"

What Erik thought was a dildo began to twitch and throb. Leaking a large amount of the same liquid down it's giant shaft.

"This thing must be expensive being to realistic...god I gotta see her penetrate her..." Erik stopped looking over his mother's plump belly.

Erik stood completely still in absolute shock as he saw that the monster dark cock was connected to his mother's crotch through a thick layer of pubic hair. He realized that the huge phallic object was not a dildo, but was in fact his mother's....Huge...Black...COCK. Laura was moaning louder now as Erik watched his mother grab the massive rod with mother her hands, clenching tightly she began to stroke the full length of her dark shaft.

"Mmmm...mmmMoM...I...This can't be real..." Erik thought feeling his his own cock throb. He now knew that his mother had been crushing his body with the huge purple head of her giant mommy cock, and the fluid was his own mother's thick pre cum.

Suddenly Erik felt Laura begin to stand up in the bath water. He quickly lost his balance and began to fall again.
