you had Large B's before but with a second of pumping the milk into your breasts you had Large C's. they looked a bit strained, perky even. curious where this machine came, you search the machine for any logo or names. a bland logo with "T.F. medicals" written on it. you et your phone out and start searching on the web. you couldn't find more than a strange genetics research facility that was later bought by china. you don't see how this relates to a machine that pumps back milk in to breasts, but it leaves a slight concerned. maybe you shouldn't buy that much flee market farming machines,... or maybe you should. you find a little panel that opens up and show a bit too sophisticated technology for you. a panel shows 'human' and a history uses, a long list of cows. you look once again your breasts, they were big now. you could make them bigger, it is late anyways, no one will bother you at this hour.
you first try to reverse it, just to be sure. you put the tubes on your nipples again put it back to sucking. it feels really go, your knees get shaky. it luckily stops quickly before you couldn't stand anymore. completely flat. just some perky nipples. pretty cute, but this is too flat for your comfort. you turn it the reverse switch on and start filling. your breasts swell back to C's and become even bigger: D, DD, E! after some time the left over in the tank was empty. you went to the living room and enjoyed the moment. sitting in a sofa with two soft sphere twice the size of your head laying on top of you. though heavy, working at the farm gave you some muscle dragging weight with you. you turn on the TV and fondle your new assets a bit.
the news says something about a virus in china close to a genetic research facility. the Chinese branch of the T.F pharmaceuticals! you perk up, still fondling. "due low resources, costs and bad practice, a mutating virus broke loose, more info, we will keep you informed". you didn't notice some milk droplets forming on you nipples. it seems their previous machine work fine though a bit weird. shows you what prioritizing efficiency over quality does, all the while you have been balancing loss and profit barely on your won farm.
