YES

Theo could only dumbly nod. But before he could comply with her orders, another flash occurred and the world changed.

Humanity: Old Rule: While the minimum breast size remains unchanged, the average breast size is now a D cup, and large breasts will be F or G Cup

Kayden had always been a petite, mousy woman. But now hanging from her chest were two extremely delicious-looking breasts nearly the size of a canteloupe. The boy could not help but gape at the way her fleshy globes stretched out her top.

Maybe he had inherited it from his Father, but the boy had always found Kayden extremely attractive. She was a frequent feature in his masturbatory fantasies, as shameful as it was to admit.

But the changes the Notebook's current Owner had made only made his stepmother even hotter. Rather than the business casual clothing she normally wore(She was a self-employed interior designer) instead what she wore could only be called a slutty porn parody of an outfit. Furthermore, the subtle signs of old age were gone, replaced by fully youthful vigour.

Kayden gave a sultry wink as she noticed the boy's perverted and blatant ogling. Of course, now she only saw it as polite flattery.

Throat dry, Theo gently slid his semi-soaked cocksock off, revealing a bulging colossus of white cockmeat fourteen inches in length. It was surreal to look at it. On one hand, Theo had the memories of his four-inch, just below-average dick. But he could also distinctly remember growing up in a world where fifteen inches was the average for Americans, and he was only a fraction below average.

Kayden smiled, sliding to her knees. Gently her moist pink lips parted, and she leaned forward. Her soft wet mouth pillows gently met the pre-cum soaked tip of his cock and she gave a gentle, slurping kiss, tongue flicking out to tease his cockslit.

Theo felt something inside himself snap, and without warning, he thrust his hips forward, bucking into Kayden's mouth. Ropes of jizz erupted from his cock as she fell away from him, spraying all over her face, clothing and hair.

Theo gasped and weaved as his body twitched and more and more cum poured out from him. It seemed that his larger cock size also came with an enhancement to sperm production because he'd never come so much.

Blinking as he regained his focus, Theo looked down at the kneeling Kayden.
