You notice your teacher is flat chested and decide to help her out by putting a secret ingredient in her coffee. The ingredient will supposedly make her boobs grow. You stay after class, where her tits grow to massive proportions right in front of your own eyes! You watch as her tits bust out of her top and stretch out her bra to a teeny tiny size. You get so horny, that during the growth process you start confessing your undying love for her. Your teacher is super flattered and impressed with how you've helped her make her breasts grow. She decides to give you an amazing titfuck, before letting you stick it in her pussy and fuck her until you cum.
