Your barrel shaped chest expanded momentarily with each breath you took. Your entire frame was huge compared to what you were used to your entire life.
Still, there was one major change that caught the most of your attention - Your huge, mottled stallionhood along with your dark, grapefruit-sized balls. Your cock was so long that it almost touched the ground, but the more you thought about it the more erect it got. You craned down your elongated neck and your long muzzle met the flat tip of your crowned mushroom. You shivered and licked your tip once, the sensations made you stomp your hind hoof against the pavement, cracking it in the process.
You tried to lap at your shaft more passionately, but your new anatomy wasn't really made for it. Despite your cock being enormous to fully stuff a potential mare's womb, your neck was still too short for you to fully take your cock into your mouth.
You were surprised how stiff your long cock had gotten, it slammed against your stomach and strong lower chest constantly. The fur, your protruding muscles and wild methodisms hitting your jumping cock only made it harder. You nickered and thrusted your hips to help your cock slap against your strong silhouette harder.
Your entire length stiffened and the mushroom swollen with each slam. You were a horse now, you didn't care if people peeked at the strange sight from their windows. You became forcefully turned into an animal, a horse and you loved the sensations of your impressive stallionhood smacking against your chest.
You staggered to your sides and swayed your head to the sides as your pelvic thrusts intensified. You snorted and panted audibly with hot fog coming from your flared nostrils and agape mouth. Your exotic belly-dancing and pelvic thrusting made your cock leak precum, but you needed more. You frantically looked around panting hard with lust in your equine eyes.
There it was - A trashcan with a hole that seemed proportionate for your mottled cock. You dashed towards it and jumped onto the inanimate object. You didn't know it would be so difficult to aim, but your cock smashing the cold metal only made you hornier.
Your eyes widened as your fat mushroom met the entrance. It was padded, you closed your eyes and imagined an actual mare to your shock. You humped the trashcan making it shake and almost fall out of its stand.
Your dark balls clenched and made you stick out your tongue as you felt many huge loads of equine cum get forced through your hardening shaft. Thick ropes of cum filled the trashcan as you pounded it blindly in lustful amok.
Your orgasm subsided very slowly and you shook your head. You looked beneath you and saw the mess you've made. Your lust was sated at least for now and so you dismounted your inanimate mate. You looked around you to make sure there was nobody around, ashamed of yourself. Your equine curse lust-addled your mind, it wasn't your fault. Nonetheless your heart pounded after your orgasm and you had to make a choice about what to do. Run away? Seek out help? Or something else?
