After looking around and seeing no one, she took the box of candy "Great, it's been a long time since I ate a little lozenge!" thought Keiko, she went into the living room to wait for her daughters, she continued to hum and with each step, her chest bounced with a sweet sound *jiggle jiggle*.
She arrived in the living room, relatively modest with the most important, a sofa and a coffee table! Keiko walked over to said couch and dropped into it, her knockers following the movement up and down, several times in a double *boing* followed by several *jiggle*; she was proud of her imposing pair of breasts and hoped her daughters would have equally large ones to carry on the Shinonome tradition.
While it was settling down, she took a lozenge from the blue box, from a known brand of mints that she started sucking happily before putting it on the coffee table; being a bit far, she had to arch her back compressing her two big breasts between her chest and her knees, left the box and repositioned herself with a new movement of her knockers.
Keiko realized that there was a fluorescent pink label behind the box.... She made the same movements again and started to read while sucking the pellet: "Experimental order for Mr. Takahachi WATANABE, owner of a dairy cattle farm in the archipelagos of [...] do not open, do not use etc etc".
The moment she read "Dairy Cattle" she choked on the pellet, slapping her chest a few times, her chest undulating in shock, got up to get some water from the tap, recovered from her emotions and fell back into the couch... she heard two big *BOING* with a much more imposing but mostly heavier downward movement and realized that her 123 cm(48in) chest was no longer... it was now a very large 150 cm(59in). Keiko couldn't believe it, how could they get bigger without her realizing it? It was during the choking, so preoccupied with it that she forgot the rest.
She stood in front of her breasts, sitting on the couch, before deciding to touch them; each hand grabbing a breast, she felt something familiar, a pleasant tingling, massaged a little and felt something wet on her erect nipples: She had produced milk.
