I make her clit extremely wet while kissing a sucking it gently for a minute or less.

From there on I exclusively only rub her clit with my bottom lip except when more lubrication is required.

She always cums within 2-5 minutes.

I hold still until she is ready again in about 15 seconds.

I rub again with my bottom lip and repeat until she has 2-3 more orgasms.

Then I move up and give her one more by rubbing my penis on her clit if it's not to sensitive.

Works every time since I stopped with all the fancy tongue stuff etc.

She has never had an orgasm from my penis due to its size and my inability to go for very long.
