The science of comparing 

The bell rang for the last time in the day at Barkington High School, followed by a stampede of students who soon filled the corridors searching for freedom. Except for three childs who moved discreetly from the mass of people and hid in the last room, the chemical lab.

"¿Nobody saw us?" asked the young hyena boy.

"Just the director" answered a tall wolf, keeping from laugh while saw the grimace of fear in his friend.

"Hey, don’t fuck with that, man!" said a cheetah a little smaller than the canine, looking down the corridor and slowly closing the lab’s door.

"Hahaha, what happened, kitty? No balls there?" the lupine asked. smiling showing all his teeth.

"No balls down there?" he spoke mocking the words of the wolf. "Soon you'll got them in your ass, idiot" growled the feline.

"Guys... relax, that's why we come here" said the hyena, putting himself between the other two childs.

"Fuck you, ass sniffer, i just come here to show to this jerk who is a true man" said the cheetah.

"Well, first of all, go fuck yourself too and second, if you're the real man you said you are, stop crying and show us," the hyena refuted, crossing his arms.

"I ... I will ... just remember the bet: the biggest one, stays with Jenny" the feline replied trembling.

With this said, the other two males affirmed with their heads and stayed looking at the cheetah. The little guy, still nervous, beggin unbutton his shirt showing a flat belly letting see some ribs and some hair with a color little stronger in the lower part of the stomach. The little guy take a moment and continued, unhooking his belt and unzipping the pants, discovering a white brief with a tiny bulge.

 “Awwr… the baby is using briefs.” said the wolf.

 “What’s wrong? i like them, too much boxers walking around” replied the hyena.

 “Ooh, knowledge of a dick lover?” asked the lupine.

 “No, just too much free time at the shower gym” replied again the hyena.

 “Sure… let’s continue.” said the canid.
 The little cheetah looked the other two guys and next down his look and took off his underwear showing his sheath and a pair of tiny balls.

 “Well… wake it up” said the hyena when he saw nothing was happening.

 “Wait, let the wolf show us first, i don’t want be the only naked here” replied the feline.

 In one move the wolf unzip his pants, discovering a black boxer with red lines, and with the other hand pull down his underwear uncovering his genitals: a fat sheath with a hanging pair of balls, fig size.

 Taking his balls with both hands aiming them to the cheetah and said: “do you like it, kitty?”

 “Nice piece of meat, man. I think soft and all i get the winner” said the hyena.

 The little guy blushes deeply, moved fast his eyes to another direction and put back his briefs. “O-okey… then no need of continue with this shit”

 “Aww… the little baby lost his shitty competition?” laugh the lupine.

 “Fuck you, Ronny!” said the cheetah finishing adjusting his shirt and before leaving the lab he lifted his middle finger.

 The other two guys keep looking at the door, they stayed stunned by the finish of their fun with the born of the sudden awakening of the little boy's anger.

 After a moment the hyena begin to walk to the door, saying goodbye with his hand to the wolf. “You win man, see you later”

 “Hey, wait a second!” howl the wolf.

 The hyena turned his head and ask: “Yeah?”

 “Wanna taste it?” said the lupine, still holding his balls.

 “What the fuck…?” replied the other guy blushing a bit.

 “Come on Ricky, we both know you want lick my dick, i know you are a faggot” said grinning, the canine.

 Rick looked fast over the window of the door and after checking he turned with a red face said: “Okey… come on, a fast one”.

 Both guys moved to a corner of the lab, the wolf jump over a stool, he dropped his pants and spread his legs, tapping his crotch two times with his hand, licking his lips and saying in low: “good boy”. The hyena knelt in front of the wolf meat, sniffed the balls and started to lick them.

 The wolf felt the wet tongue, sigh and put a hand over the head of the hyena boy, gripping hard his hair, feeling how his member came out of its sheath and began to swell while suffering a burning in the base while his knot rose and was free.

 The hyena gave a long lick from the base of balls to the wet point of the dick and began to suck it with eager filling his mouth with lupine cock, feeling the salty precum and swallowing it.

 The wolf got up from the stool, standing in front of Rick and holding his head with both hands and began pushing against the face of the hyena with force, snarling.

 When he felt the dick occupying almost all his throat, the hyena opened his eyes and tried to free himself, hitting Ronny's leg with his fist, while his eyes filled with tears.

 “Shhh...i’m almost done, slut!” said the wolf, pumping faster and dropping his seed with rage in his friend, flooding the muzzle of the boy, at the moment he shouted: “¡SWALLOW IT, BITCH!”.

 Ricky took it all, agitated while running out of air. At the moment he felt all that fluid reach his stomach, he freed himself from the wolf's hands and stood trembling, wiping with his shirt sleeve a bit of semen on his cheek while coughing violently.

 Ronny sighed as his cock drenched in spit and cum, still dripping some drops on the floor. He ran his hand over his member to clean it and then patted Ricky's cheek and smiled.

 The hyena growled and punched him in the face very hard, knocking him on the ground and yelled at him: “I’m not you bitch, fucking jerk!”.

 The wolf sat up from the floor, brushed the dust off his uniform, pulled up the boxers and the zipper of his pants. He licked his lips and stared at the other boy with a smile before telling him: “Wanna go for a drink? my father have some beer in the fridge and he isn’t in the city”.

 “Sure man, let’s go! ¡Oh! and we must stop a moment at my house for get a bit of money and buy some snacks.” said the hyena with a smile in his face.

 “Anything for my hen” said the wolf, resting one of his arms on his friend's shoulder before receiving a punch in the ribs while both left the school lab.
