Well, it's all well and good if it works but why faff around with 5 separate visits spending what, a few hundred quid to get there? Couldn't you just cut to the chase and offer her £150+ on first visit or even better, just visit an escort for £100 and ask her to waft her hands up and down your body for 5 mins before fucking your brains out?
You may think your getting a unique privilege when you finally fuck the masseuse but if she's letting you do it, sure as eggs is eggs she's let others do it too. I'm not knocking masseuses, nothing wrong with a relaxing rub down - I just can't see the point in using them for sex if that's what you're after
