You start jerking off in front of me and I get a weird feeling in my chest. Its a little strange but I tell you to continue because I want to watch you cum. You keep stroking and all of a sudden my boobies start getting bigger. I'm so excited by my new big boobies! I tell you to keep going and make them bigger and bigger until they burst out of my button up shirt. Once they're out, I admire my huge boobies and tell you that I think your cum will make them grow even bigger! I tell you to jerk off faster and cover my huge nipples. You know you totally want to help them grow
