"Happy twelfth birthday, sissy," the middle-aged dog grunted while his thick adult dick flexed inside my abused preteen asshole. He yanked his swollen knot out after the first shot of cum and slipped his cum-slick cock free to shoot the rest of his warm load all over my little cock and my chubby belly.

"Get that little faggot to suck it clean like the rest," another man growled out while he jerked off in my face. I was in a daze, drunk on cum while I nuzzled at the man's cock head, the mess of cum all over my face smearing off onto his shaft.

The dog put a large paw on my chin, turning my face towards his filthy cock as the last of his cum dribbled out over my snout and glasses. I opened wide immediately, obediently taking that cock into my maw and slurping the mess of sperm and filth from it while another man held my hips, another bare cock sinking inside me for the 30th time that night.

Or was it the 31st... I'd lost count by now and all I knew was I loved pleasing my daddy's friends. I was supposed to take twelve loads tonight, one for each year in my age, but so many more men came and they just kept cumming.

The mess of dozens of loads of cum inside me kept my asshole slick and ready to use, the cock roughly pounding me finishing up in a hurry. The stranger was groaning while he held his dick balls deep inside me, his cock flexing while load after load of fresh cum flooded me, quickly mixing into all the sperm from before.

The cock I was licking clean finally pulled away and all I could do was whimper until the one in my ass slipped out and found its way to my maw. I happily sucked it in once more, slurping that messy cock clean and giving it a massage with my tongue while another cock forced its way up inside my well-used sissyboi cunt. It felt like a horse for the first time tonight, thick and throbbing. I couldn't help but let out a slutty moan around the cock stuffed into my maw.

"Heh, my little girl loves her horse dicks," I heard my daddy say, my tiny dog dick achingly stiff as it bounced against my tummy from the horse's rough thrusts, globs of cum from all the other men bouncing off my jiggling belly.

"That little baby dick is gonna shoot again, just look at it. I bet this'll do the trick," the horse grunted out while slamming his dick balls deep into my cum-stuffed asshole, his cock head flaring as he unleashed the biggest torrent of cum yet. It overflowed my asshole, all the sticky slimy cum pouring out around his cock and soaking my fat butt and my tail while I came with the horsey, my little preteen cock twitching and shooting a few tiny ropes of cum onto my tummy to blend in with all the other loads already coating it.

The horse slipped free after a moment, leaving my sloppy asshole gaping extra wide while cum drooled from it, the filthy scene getting an approving grunt from the next man to step in and plug me up.

"Ahh~ That's you, isn't it, Daddy?" I grinned, looking up to see my wonderful daddy slowfucking my well-used sissyhole. He smiled back down at me, his already swollen knot easily popping in and out of my gaping asshole while the horse slapped his dirty dick against my snout. I just giggled, happily licking it clean while my daddy bred me for the second time tonight.

Daddy was the first and now the last to shoot his cum inside me tonight and I pouted thinking it was over.

"Alright boys, who's ready for round two?!" Daddy said as he slipped his cock from my asshole and joined the horse in rubbing his filthy cock against my face, trying to slip it into my occupied maw while one of the strangers happily stepped up for the second round, slipping his cock deep inside me.
