Is it not just a wank?? Hand Relief??
Certain women will chat shit about the ancient art of lingham massage. If they feel it lift them above other prostitutes, I let them do it. But yeah, it's a wank.
That said, all rub n tug merchants are not created equally. Purely anecdotal but in my experience, weirdly, the pretentious ones who call it a lingham massage have a far greater talent. Best orgasm I ever had was from a lass in Farnborough who wanked me off better than I ever have.
