Oh, I am very sorry, i didnt know you need help on spanish
however your english seems very good!
I will explain it on english and I hope you will understand:
First put some oil on your breasts, then put the domes over them and start pumping.
There are two pumping techniques:
1)pump and hold
2)pump and release
For some people it works better with pump and hold and for other ones pump and release. you have to find which suits best for you.
pump and hold is when you pump a little bit (when your boobs get a little bit red, but not purple) and you hold it for like 30-60 minutes
pump and release is when you pump, hold for a minute and release and do it over and over again for an hour.
good luck with your noogleberry!!!! and dont forget to drink a lot of water, it helps the boob growth!!!
GOOD LUCK!!!
