Cow blowing.
As it turns out, blowing up your intestines does more than put pressure on a woman's inner clitoris and the occasional orgasm, the uterus is stimulated into releasing growth hormones that enhance regeneration (gives a youthful look), growth (a fuller figure), and,even more important than the two, a tighter nethers (everything feels SO much larger now!)
Before pumping anyone is advised to see their doctors and get inflation recommendation on how to proceed with their internal integrity - girls with a redundant colon are the luckiest! - and begin with only the lightweights such as enema bags and bulb pumps (never insert the compressed air station!!!).
Considering the maybe/maybe-not myth that bigger volumes will get both bigger and faster results, mind that if you overdo you can strain or tear a bowel and even die(!), and despite all the warnings more and more videos are surfacing that show women willingly busting their guts for the ultimate climax.
