Your cock has swollen to twice its original girth, and its shape has changed radically as well. Swollen and flared trumpet-shaped head tops a long turgid, shaft drooping slightly from it's new found length and heft. Your human foreskin morphed into some medial ring of tough fibrous flesh and a leathery sheath. Below hangs a swollen pair of testicles, much larger than before and bound in taught peach-fuzz skin. Your human pubic hair flowing away beneath the shower water. You reach down and touch yourself, half afraid that you will feel something rubbery, but to your relief you do not. You realize that your genitals are now a flesh and blood copy of the Devil's Dong equine dildo.
Having flopped out of Gina with an audible pop, your flared head seems to be the only thing softening. Your newly enlarged balls are each as big as your fist, and they too ache with desire. You give your new-shaft a half-hearted stroke. Although somehow softer than your human form, your new, though slightly floppy, flesh is still turgid and burns for another romp with your new lover.
Lustfully you look toward your newly augmented lover. Gina meanwhile seems to be distracted indulging in her new curves. One of her hands lovingly stroking her new hips, while the other rubs at her--wait her nipples are different now. Her quarter-sized areola are practically gone, condensed down into thick cherry nubs. 'Just like a mare' you think. Quickly your gaze trace to her other hand, now tracing through her garden. The very structure of her once human flower is changed too. Layers of delicate velvety labia have collapsed into singularly thick meaty elastic horse folds dripping from the hot shower water.
Noticing your gaze, Gina's hip probing hand grips your new equine member by its now softened, yet intensely sensitive girthy flare. Her delicate touch elicits a deep throaty growl in your throat. "Love the new look" she purrs before bending slightly to kiss the fist sized helm of your cock. Her nubile ruby lips, like soft rose petals, sending pleasing tingling elation down two feet of turgid masculine length--your new equine length. With new found enthusiasm, her pale face twists with greedy desire as she directs your tumescence out from the shower spray. Her grip tightens as it spirals down your amber brown shaft, pumping a mighty glistening drop of lust. It glistens your protruding urethra for only a second before her tongue deftly laps it away. "You taste better now" she teases voice muffled while suckling on your cum-tube, the filtrum of her lips lavishing the small dimpled depression at your tip.
Seed burning in your loins, you slide your hands into her wet hair. "Enough" you growl, before pulling her head away from your new equine one. With lust tingling at every muscle, shower water beading upon both of your improved bodies, you bend her over. 'Mare cunt, fuck it' rings some primitive version of your own ego. Shower water makes terrible lube, the first touch of her inner softness is rubbery and difficult. Gina gives a sharp shill cry as she brings her hips down to yours. One of her hands reaches down to tease her flaring clit before grabbing your bloated stallion balls. Your both plunge into each other like rutting animals. Bending down beneath the shower water, you wrap one arm around her chest. Tweaking one of her strange new nipples with your grip, while instinctively biting down on her neck, teeth purposefully drawing no blood. She moans, resonance of her chest greeting your deep thrust."Good" you muffledly grunt into her flesh between your teeth.
