“Drink this,” Mary instructed as she handed Sarah a vial. She eager swallowed it down and cooed as her breasts swelled up a cup size. “Again,” Mary ordered, and again Sarah drank the vial. She moaned as her boobs ballooned bigger. “Again,” she repeated. Sarah let out an orgasmic cry as her breasts doubled in size near instantly.
“My boobs are even bigger than yours,” Sarah moaned in awe and delight.
“Again,” Mary ordered.
“A-are you sure? This feels amazing, but my tits are already so big. I can barely…” Sarah was cut off as Mary loomed over her. Lower lip quivering, Sarah opened her mouth and Mary poured the vial down her throat. Sarah screamed in pleasure as her boobs doubled in size again. Now each tit was the size of her torso. Knees shaking in ecstasy and in effort, Sarah was lifting her incredible bust with both arms to keep her from being pulled over by them. “Mary…” she gasped, her head in a daze of sensations.
“Again,” Mary stated.
Sarah could only nod, mouth hanging loosely open. She drank the vial and immediately collapsed onto the ground before being lifted back upwards by her massive breasts, each now as big as her entire body. Mary circled the 30 year old pair of tits. She mussed on what to do as Sarah stared off blankly into space, her mind completely preoccupied by the incredible bliss she was experiencing.
