"Ally, take it easy. That's just the fever talking." I said, leaning away from her. She was right earlier, I should've listened to her and left when I had the chance. Ally's much stronger, her arms had a tight grip on me. She wasn't going to let me go, not without a fight that it.
"But I need you. I don't want to leave me alone, not like this. Don't you love me?" she crooned, snorting air onto my neck. She turned my head around so that I was staring straight into those big brown horse eyes of hers.
"Well ya, but I don't want to..." My sentence is ended as Ally pressed her thick lips against my own. The bristle-like whiskers on her nose rub awkwardly against my face, and her huge lips feel strange. Like someone is pressing rubber on my face. Ally was trying to slide her tongue into my mouth, but I wasn't having any of that. I kept my mouth clenched shut, and eventually she pulled out of the kiss to give me a frustrated look.
"Jared, don't be such a poor sport. You want this as much as I do." Ally cupped her massive breasts, jiggling them in my face. Oh fuck, that was really hot. They were just so freaking big. I wanted to take one of those fat nips in my mouth and suck on her. I really did, but I held back. That didn't stop my pants from tenting a little.
"See, you do want this." Ally looked at my slight bulge. I still rebuffed her advances, jumping to my feet and backing away.
"Come on, you can beat this Ally. Fight it, you're stronger than some stupid fever." I said, slowly moving closer to the door. I stood frozen in fear as Ally rose form the bed and strode towards me. I couldn't move, and Ally pressed her body against mine. I felt the heat from her crotch radiate to my torso, igniting a fire in my own gut. The tent in my pants got more prominent, and my own resistance was slipping.
The room smelled so good. Everything smelled so good. I was conscious when Ally started undressing me, and yet not. I knew what was going on, knew what would happen if I didn't put my foot down, and still I let it happen. Ally pulled my shirt over my head, then slipped my pants and briefs to the floor. My penis was fully erect, small drops of pre running down my shaft. Ally took my dick in her large hand and started stroking it.
Her pumps were slow and methodic, and they more than did the job. My orgasm was building, slowly but surely. My balls felt so full, like I hadn't cummed in days. I needed this release, or that's how it felt anyway. I bit my lip, cursing myself for enjoying this because I knew I would hate myself later. I didn't want to end up like her, another victim of the fever, but it was too hard to fight it. I gave in, my load shooting from my hard phallus and splattering all over Ally's equine face. With that large tongue of hers, she not only licked the spunk from her face, but then licked it off my cock like she was licking an ice cream cone.
God, that felt even better. Like a million times better, her tongue was so big and soft. Her licks sent shivers up my spine, and I threw my head back and moaned. Then she started sucking on the tip. I almost blacked out. I was gripping her shoulders at that point, begging her to take more. Her mouth was so warm and wet, and roomy. I wasn't very big, probably average. And Ally's mouth was so massive that after engulfing my cock, she started sucking on the bottom's of my balls. It was so intense, I felt something in my chest bubbling up.
The next time I threw my head back, a whinny escaped my lips. It felt good, natural almost. And that's when I knew I'd reached the point of no return. The heat that had been centered around my crotch was spreading fast. I didn't know how long it would be before I started to change, but it wouldn't be too long. Ally stopped sucking me, she seemed to sense that my transformation was eminent. She stood up on her hooves, looking down at me, and made a gesture to her wet slit.
Standing in front of me like that, I was eye level with her crotch. I couldn't stop the erection and I didn't want to. Seeing her own horsecock displayed before me, mottled and erect as well, I wanted it. Something inside me wanted to take that cock, and have Ally shoot her load until it overflowed onto the floor.
"You've earned it stud. Don't keep me waiting." she said, making another motion to her erection.
I'll admit, it wasn't the first time I'd sucked a dick. Well, not exactly. It was the first time I'd sucked someone else's. I'd given myself blowjobs before, after a lot of practice and a few dozen yoga classes. Nothing could have prepared me for Ally's horsecock though, except maybe another horsecock. The head alone was enormous. Probably three inches across, with plenty of pre-cum dribbling down the bottom length. Her pre tasted salty, not unlike sea water, but without all the fishy tastes too. I slowly took more and more of her beautiful phallus, until half the length was within my maw.
Something inside me clicked in that moment. I felt my body let go of whatever inhibitions I might have had left. Hair began to sprout all over my skin, first on my chest and then spreading downwards. Unlike Ally, the hair on my body was lighter, more red. I pulled back from Ally and touched my body. My hands were bigger, the nails on my fingers covering the ends of my digits. It was as if I had mini-hooves rather than actual fingers. I continued to stroke my new chest hair, fur, whatever. It was surprisingly soft. The bottoms of my hands were firmer, not exactly like pads, but definitely harder than human tips. My pecs and abs felt harder, even under the new layer of chestnut horse fur. Then the hair crept down to my groin, meeting my pubs.
Ally appeared to be just as interested in those changes as I was. As more and more hair enveloped my junk, I felt blood rushing through my veins. My cock was erect already, and as more and more blood flooded it it grew. It was like someone was pulling it away from my body with some invisible string. Ally crawled forward to kiss the head, and as if under her touch, the head swelled.
"Ah, Ally don't...it's..." I tried to make her stop, the sensations were too much. But it was too late. The tip of my cock flared outwards, just like a proper stallion's penis would. The shaft swelled until it was probably three or four inches thick. A ring of flesh developed about halfway down my length. More skin bunched up at the base of my cock, forming my new sheath. My cock started to darken, turning black in areas while maintaining a few patches of pink. As soon as the changes finished effecting my dick, my balls started to change. Wrapped in soft chestnut hair, they engorged to the size of grapefruits. Shifting my weight from one leg to another, I could feel the cum inside my sack swishing.
"Looks like you could use some help with that." Ally said. She'd been attentively licking the tip of my cock, but now started to take the full length into her muzzle. It felt so much better this time. My cock rubbed the top of her mouth in a very different way. It was very pleasurable, different but pleasurable. I couldn't even imagine what her insides would feel like, let alone if I'd be able to handle Ally's fuckhole given I was seconds away from blowing my load into her mouth.
