One of the women I see has a remarkable reaction to nipple stimulation,
Generally she doesn't react much to kissing or sucking her nipples and I tend to leave these alone. But what she does love (and I enjoy giving) is a thorough work-out of my tongue on her clitoris and surrounds aided by a bit of finger trembling on the front wall of her vagina. This gets her pretty well aroused and I've learned over many years to watch for the right moment to go for gold. Her breathing becomes irregular, her grip of my head in her thighs tightens, her face reddens and then the coup de grace
I simply reach up and lightly touch her nipples with my fingers. She shudders, cries out and threatens to crush my skull. Her orgasm doesn't last very long but afterwards the warmth of her smile and the hugs she gives me are a lovely reward for my efforts.
Usually when we meet it's a two hour appointment and I can give her three of these orgasms. I often think she should pay me but I'd settle for freebies. I actually get 2003 rates so thats not bad.
