You watched as your Professor's butt begin to expand, while you pulled out of her, and stopped once it was almost as big as the pillows of the bed you were both on. The scientist turned around, and found that you have spotted her butt was now bigger than your own penis, as she turned around, and continued to suck you off.
You had a feeling that the professor's body was going to get bigger, as she began to suck on you penis, and it would be too small for her to have sex with. "Do not fret, my student," Ilene explains, and placed her breasts in between your penis. "I won't be the only one who will be growing to become very thicc. You will have a penis big enough to penetrate me as soon as I'm done giving you this breast-job." You then watch as the Professor moves her breasts up, and down, while sucking on your penis.
