As you chose to try and walk through a dark alley in the middle of Makarna, you in yelp in surprise as a damp cloth covers your mouth and your vision begins to darken as you feel yourself fall to the ground and everything fades to black.
Chanting and whispering filled the air along with a gentle cool breeze which tickled your bare chest. You try to cover yourself like you would have you a blanket, yet your hands lay numb and unmoving. As memories of your recent ambush, panic filled your heart making you struggle only to find that you had been stripped of all your belongings and that you were bound to a slab of metal, its cold sting making apparent its make.
You try to take stock of the situation looking around frantically looking for an escape. Above you a bright golden light like a spotlight shone upon your bound figure, making apparent your meager package and making you blush. Trying not to get hard you try to crane your head to your sides. On either side you are surrounded by hooded figures whose faces are obscured yet had their black muzzles peeking out barely visible. 
They continued to chant in unintelligible words that seemed to draw power of some sort. As they went on with their chanting the spotlight above you began to shine brighter and cover the entire room, revealing enough gold to buy out a small country. Gold lined everything from various glyphs on the wall, to the intricate lines adorning the sandstone floors.
One of the hooded figures raises their paw, and everything went silent. He pulled back his hood revealing a face reminiscent of canine but blacker, sleeker, somehow more elegant yet at the same time feral. Not being given enough time to admire his face he opened his mouth and began to spoke in their tongue, then later in a language you could understand.
“Welcome brothers! Today we celebrate, for the sacred vessel has finally arrived” with a flourish of his hand something small and golden appeared in his hand, the glaring light glinting of its gilded surface making it hard for you to make out what it is.
“Long have we waited for this sacred day, I have been head priest for as long as I can remember, waiting for the day we can finally bring our master to this world, and today is the day” he then began to move towards where you were bound, his clawed finger gingerly tracing lines all along your body, pleasure rippling all over your entire body as lines of gold were left where his fingers had gone, faintly visible.
Warmth began to spread along your body and your member began to harden, and all who were in the room began to gawk at your member, meager as it was.
With your face reddening in shame, surprise became apparent on your face as you felt the same clawed hand running along your body moments ago slowly stroking your half-hard member into full-mast. It barely filled his palm, yet he went on, stroking at varying speeds edging you until you felt the need to hump into his paw to try and get off.
As you approached the edge of orgasm, the lines along your body glowed and ecstasy filled your body. his hand had left your member hard, needy and leaking pre only for him to breath on it. warmth enveloped you as that single breath sent you over the edge and came, your seed flying through the ai as you tried to hump the air, some of it even getting on your face.
“With that, the ritual may now begin” now all the figures surrounding the table removed their hoods revealing them all to be the same canid species as the high priest who just made you cum.
Drumming filled the air from somewhere you couldn’t see. Hands began to undo your bindings, yet made no difference as those same hands began to raise your body spread eagle and held you in place. The breaths of countless males breathing down on your naked body and the feeling of their hard-ons poking all over your body got blood pumping back into your member into half-mast only for the high priest to grab you by the balls and something cold wrap around the base of your cock and balls, not letting you get hard.
The pressure you felt around your loins made you look down to what he did only to be surprised to see their artifact now adorning your meager member. The gem laden gold now glinting less in your shadow making it impossibly clear for you to identify what the artifact was, a golden chastity cage.
Your member strained against the cage, of which was already leaking pre from being turned on by those around you.
You waited with baited breath, still unable to speak or move as the high priest began to chant. Black fur began to spread all along your body starting from the accursed cage, your balls became slightly bigger, along with the muscles all along your body from your now digitigrade legs to your muscular arms and bulging pecs. Small claws began to grow out of your nails and your ears began growing like trees pointing upward. Your face elongated into a snout. The hands holding you up let go one by one, followed by panting breath. You fell to the ground with a thud and looked up to the high priest, smugly smiling down on you.
“Rise our lord and prince, we shall get you cleaned” unable to say anything your body moved on its own taking the Jackal’s hand. You were led through various hallways adorned with gold, that upon closer inspection, was placed to keep the apparently old structures together. Hand in hand he paraded you through the halls, your naked visage on display for all to see, save for the golden cage adorning your crotch. Stronger and taller you may be, but still a prisoner in the end.
