Feeling more confident and relaxed John looked at his mother and smiled, “Well how about you get on top and give it a ride it’ll never forget?” he suggested with a hint of authority.
“Sure thing, baby” his mum replied with a grin as she slid over his body, positioning herself just right, lightly holding John’s cock with one hand as she guided it into her wet pussy. They both moaned as it slid in and within moments John’s mum was rocking her hips back and forth. John’s hands instinctively went to her breasts, groping the large firm forms, Diane tilted her head back in bliss as her hands pressed John’s deeper into her fleshy mounds, moaning at the contact.
As John played with her tits, he slowly lost himself to his basic instincts and started thrusting up in time with his mothers ministrations, “Mmm yeah baby” Diane moaned, “Give me more!” she continued. John wasn’t really paying attention to her at this point, but his subconscious was, and as they continued to grind their hips together John felt a multitude of changes start to take place: first her felt his mum’s breasts start to swell larger in his hands, quickly overflowing his palms, quickly followed by what felt like an increase in pressure around his dick. Tearing his eyes away from the expanding chest, he saw his cock was getting bigger, stretching Diane's pussy ever wider, as she clamped down on him ever tighter. “Oh yeah baby, that feels so good!” Diane panted as she felt her pussy walls stretched.
All this only made John thrust into her harder, which seemed to increase the rate of growth in Diane’s chest and his man-meat. Soon, they were both grunting and moaning, each nearing orgasm. Their pace increased, Diane’s huge melons bouncing wildly despite her and John’s hands pressed into them.
Then it hit, like a freight-train. John orgasmed hard, shooting a large load into his mum’s dripping snatch as his hands tightly gripped the huge baby feeders; moments later Diane peaked as well, her pussy clamping down on John’s enlarged member as she grunted her release.
Both parties spent, Diane collapsed forward onto John’s chest, her new super sized boobs acting like an airbag (or two!) between them, his shaft was still lodged in her cunt. As they both recovered, John looked down at the new cleavage he had created for his mum and was impressed with his handiwork. He’d blown her puppies up to the size of basketballs and they appeared to be just as well firm and high as before, just much, much bigger. As he admired the sight, the toll of the recent activities took over as he felt his eyes get heavy before drifting off to sleep. |
