Mistress Ayn,

Ah, the nipple work and your sub saying "harder" brings back some wonderful memories of a Mistress I used to see many years ago. She loved working over my nipples and I loved her doing so. During one particularly hot session she kept returning to them and I kept begging her to keep hurting them. They were very, very tender and sore for almost a week after that session!

I'm curious about one thing- the device you put on your sub under his bra that twisted his nips. Sounds wonderfully wicked and I wonder if you have a photo or link to one of the device.
