I had an early affair partner say exactly those words, lol.
She had put out a SexyAd stating that her husband had never given her one orgasm, and she'd been reading about multiples. I replied offering to help.
The age difference and experience counted, she was 23, I was 52, and her husband was 28 & only got himself off saying "it's not about you" to her, duh! I thought that was cruel.
We were a country apart but I travelled for business. She invited me over for a 2 week stay when her husband went off on a business course.
That was her response on our very first night and she did become addicted.
It has happened a few times since, though not with exactly the same words, lol. You triggered a dream memory there. Thanks.
