You wince in pain as the tightness starts to squeeze you. Quickly, you undo your belt and then you pants just in time for a swollen growth with four protruding nubs on it. You can hardly believe what you're seeing. A sudden rush of blood leaks from your head, making you dizzy, while your new growth seems to swell heavier.
"W-what's happening to me?" I mutter as you lean against a wall. You slid down to a seated position, the swollen growth a pink thing, veins and more teat-like nubs taking form with every beat of your heart. Looking across the aisle, there is a mirror on the bottom shelf which reflect a more drastic change taking shape under the udder.
You look closely, watching in reflection the sight of your cock shrinking, your balls as well, into your body. Your head feels wobbling and you try to reach under the under but only manage to graze your cock as it dwindles into a growing slit between your legs.
