Many women are curious and love experimenting in sex, which is why CFNM ladies enjoy all kinds of naughty and kinky stuff, including the act of cock pumping, considering they always have an obedient male at their disposal. These mistresses will do cock pumping for multiple reasons. Some will simply want to satisfy their curiosity and see whether and how it works, watching as if those will actually increase the size of their slave’s cock, while others will use it to actually have a bigger dick to play with afterward.
