Outgrowing Her Boyfriend

Although Selena's breasts were already huge, her wide arms signaled how truly titanic she wanted them to become.

Too bad that her boyfriend Justin didn't seem to share her excitement.

He only grew increasingly intimidated by this unexplainable display of supernatural expansion powers.

Of course as a growing woman, Selena also had growing sexual needs. And if Justin wasn't up to the task, it was definitely time for a new boyfriend. With monumental tits like these she would surely be able to find a real man to properly appreciate all of her.
