Step inside the room, get between the Bull's legs.
From Create Your Own Story
You step into the room and the Bull shifts one of his massive thighs to hang off the cot, making room for you between his legs. You approach slowly, stunned at the size of the man - he's all muscle, his thick neck hitting muscular shoulders, his wide chest dusted with black hair that grows thicker down his ripped stomach as it approaches that monster cock. You lay down on your stomach at the bottom of the cot, and press your face against the man's heavy hairy balls. You slobber on the bottom of the shaft of the Bull's dick, trying to warm up your mouth, and you concentrate on the man's heavy hairy balls, licking and sucking at them while your hands rub along the man's rock hard stomach and chest. His heavy hand settles on the back of your head and with his two hands, he shoves and guides your mouth higher up onto his meat.
"Fuck," the Bull's voice is deep. "If I wanted my balls licked, I'd buy a dog. Get it in your mouth, you stupid cocksucker." You glance up, and he yanks on your hair, pulling your lips off his balls.
"Well?" he growls.
You decide to give it a shot, and take the Bull's meat in hand, opening your mouth as wide as you can, and lowering your face onto his dick. His cockhead slips past your lips with effort and you make it about half-way down his cock before his flesh hits the back of your mouth and you have to pause, breathing through your nose, trying not to gag.
"Fuck yeah," the Bull's hand tightens in your hair, "that's how it's done."
He pushes on your head, and you struggle desperately not to gag as his cock hits the back of your throat. Tears stream out of your eyes, but you literally start to swallow his meat, unable to breathe on the full ride down his shaft, feeling his pubic hair hot and sticky with sweat against your face before he relents and you can back off his cock, moving up enough that you can breathe furiously through your nose.
"That's it," the Bull's voice vibrates through his chest. "Worship that dick."
It's worthy of worship, that meat. You go down on him again, feeling his cock hit and pass through the back of your throat with that same sensation of panicked suffocation, and this time his hand relaxes a little, letting you set your own pace. Soon his low rumbling is gaining pitch, and his hands grip tighter in your hair again, pushing you harder and harder. You start to suck the massive cock a bit faster, never quite getting used to the girth, but finding a rhythm that you can manage without gagging or passing out under his strong shoves.
When you bottom out on his cock once more, his hand tightens in your hair, and he tugs you off his dick completely, threads of spit dripping from your sore mouth onto his thick, swollen monster of a cock.
"You ready to get fucked, cocksucker?" the Bull asks. He tugs on your hair hard, pulling you so you nearly crawl up him, your hands roaming on his hard hairy chest, and your cock grinding against his huge thick meat. The size difference between the two of you is almost comical, your slim young body so small and vulnerable compared to his immense, muscled bulk. His other hand reaches around you, crushing you against him and one of his fingers roughly rubs against your ass. You arch your back, and he laughs, pushing his finger into your ass to the first knuckle with a rough jab.
"Damn, you're tight..." he smiles, and it's not entirely friendly. "Try not to scream too loud, eh? I don't want to get kicked out again."
You...
