Double her pleasure

Here’s some hard science:
Playing with her nipples may excite the part of her brain linked to genital pleasure.
A recent Rutgers University Study found that when women stimulated their nipples,
the same brain region that lit up when they masturbated was activated. “There may be a fusion between the sensations, which can explain why both feel erotic,” says study author Barry Komisaruk, Ph.D. And yes, it’s also likely to happen when you stimulate her nipples, he adds.
