All right, let's try this again, step by step. I've a story idea, but it takes some background.
My idea is, for me, not that new. I think I have at least one old Addventure eppy with Drum Role in the title, and I even recall discussing this and MunchWolf replying "I like bongos." I arrive at my concept of the "drum" this way:
To date, I've been unimpressed with efforts to deconstruct our love of the breast. I think there's a tendency for us to stroke our Vandyke beards -- or our chins, where our Vandykes would be -- and say "Hmm, yes, clearly an infantile obsession with what fed us as infants."
Personally, I find this as unsatisfying as the "theory" that breast love grew out of the breasts' resembalnce to the buttocks. Please, give me a break. We men have our problems, but we can determine whether or not we are boob men or ass men, thank you very much. Similarly, while some of us may indeed be into lactation, for the most part I'd say we see the bosom, not as some literal source of nourishment, but the focus of an impulse that has matured into something else.
Speaking for myself, I see breasts as oxygen tanks -- not so much for the woman as for myself. At the end of a day, it is good to go to a woman (preferably one you know) and say "Let me at 'em!" and just smother yourself in them. They are oxygen after a suffocating day, they are the pillows of the too-long-deferred bed of rest and play.
I wax (or possibly wane) poetic like this because I consider a love of breasts little different from a love of kissing. Hominids may once have passed food along to each other by mouth, and kissing may have arisen from that, a point exemplified by the spaghetti scene in Disney's Lady and the Tramp, yet I doubt that many of us really wish to pass actual food along that way. So goes breasts.
However, as long as breasts are fundamentally milk glands, this confusion may go on. I have zero against pregnancy and breastfeeding, that's not really the point. I'm only saying that Nature designed us WITH lust but not FOR lust. Making "little ones" was a higher priority than making whoopee. To be FOR lust, Nature can use a push.
My push is a functional one, the andromedary gland, known as the drum for short. Breast lovers need not worry -- superficially, it looks and feels very much like the original mammary gland. All that has really changed is its function. Whereas the mammary gave milk, the drum secretes chemical, not for an infant's benefit, but the benefit of the woman herself.
