Jack found his choice in the body drawer. Jack passed the vial to Mary, careful to cover the label.
"Here you go," Jack said excitedly, "it's from the body section."
"I think I want..." Mary thought aloud slowly then smiled, "three quarters of it." Mary swallowed the contents, nearly drinking it all in her eagerness.
"It tastes, milky?" Mary pondered as she passed the vial back to Jack, who put the cork back on and watched the contents refill as he replaced it. Mary then let out a startled gasp, surprising Jack. Mary grabbed her chest as her heart rate increased, as she felt swelling in her torso. Mary soon felt her boobs being pushed up from something below them. 'Is my belly growing,' Mary thought yo herself.
From Jack's perspective, he saw four bulges begin to swell below her boobs. Jack smiled as the vial took effect.
Mary felt her shirt stretching over her skin, she grabbed the swelling flesh and nearly came from the sensitivity. Slowly, the swelling began to take the form of breasts as nipples began to push against the fabric. Mary began to grab and fondle her newly grown breasts, lost in the bliss. Jack wanted to jump on her right then and there and slowly approached her, grabbing the lowest pair. Mary let out a gasp in surprise, "w-wait, Jack we need to finish this game. Oh don't give me that look, I'm horny as he'll too, but imagine what we will experience at the end." Mary looked down and examined the breasts noting that each pair was slightly smaller than the pair above them, going from her F-cups, then DD, and finally C-cups, each pair perfectly outlined by her shirt nipples erect. Mary glanced at the game timer and saw it was at 1 minute and smiled. 'No way he can win this round.'
