I love rough tit play. I have had one sub friend who enjoyed clamps, tit spanking, whipping and all manner of rough stuff.
I like the look of pierced nips, but would not encourage it. Maybe I'm old-fashioned.
The thought of a woman licking or sucking or biting her own nipples gets my cock hard. I can suckle a woman's nipples for hours. I have gotten certain women to cum from this alone. I love big breasts, but small ones can be very sensitive (and sexy) too.
Adjustable clamps are great. I love letting them hang and pull on nips as a lady moves around. I like adding weights to nipple clamps. Or connecting clamps with a heavy chain.
I love to lift a breast by the nipple and shake it or let it drop. I could go on and on. I would love to chat about this with any lady so inclined. Check out my stories. Many of them are big breast/lactation/tit torture oriented.
Used to love the nipple play stories in specialist big-tit magazines like Amazons, Peaches and Juggs. Pages and pages of teasing, stretching, nibbling, tying, clamping and general erotic tit-torture. Every imaginable term or metaphor for breasts was used, and then some. All taken to the point where it was often downright ridiculous, but still desperately hot. Any sex was almost an afterthought! Love to read more fantasies that purely obsessive.
