You can't help but keep admiring yourself in the mirror. Everything about your body is perfect: the massive feet, thighs that could crush trees, abs harder than steel, arms like balloons, a chest that'd make Mister Universe jealous, and your face was just perfect. And the hair, a perfect trasure trail, dark, but not too dark, hair all over your legs and arms, lighter on your torso and a beard like a lumberjack. Your cock was thicker than a soda can and had to be 12" out, soft. You walk over to the pile of jockstraps and put on the gray one, just to see the bulge your monster cock leaves, but pulling it on makes it feel like your skin is turning inside out. Falling over, you watch your body change back into its pale and scrawny self.
"So it is the jockstraps," you say as you reach for the bear one again. Putting that one on, you feel the transformtion take effect again and then stand up. Outside, the sun has set once again, but the moon is full! You remeber the intensity of last night and winder what will happen this time. In the hallway of your dorm, you can hear all the other students going back into their rooms, and eventually, the lights going out. At 11:30, a sharp pain stings your ass. You think you'll become beefy again or that another bear is behind you, but in the mirror you can see your ass swelling. A peculiar scent fills the room, and you can follow it through your dorm building.
Making your way off campus, the scent leads you into a small wooded area about a mile away from the school. As you continue inside, you feel the transformation begin again as your cock swells past it's regular 12" and keeps expanding. Your arms and legs are being pulled from your torso, making you taller with a wider wingspan. Your torso extends in proportion to the rest of your body, and all your muscles are slowly ballooning outwards, as if their careful to make you look just right rather than a muscle freak. An itch spreads across your body as your hair grows out of every follicle, and it looks like it's taking a darker hue, but it's hard to tell in the moonlight. At the end, you reach 6'8", your muscles are massive, and your cock is swinging between your kneecaps, reaching 16" soft and 10" around. Your balls are dangling between your thighs, as large as watermelons now. It should be hard to walk, but your incredible thighs make it easy to pull your balls along. Your hair is just longer, making you look more like a bear than before, and it's hue matches perfectly with your barely tanned skin.
Continuing in the forest, a clearing opens where those two men from the previous night are. The transformation has clearly affected them as well, but it was easy to tell them apart still. Behind one of them stood a young man, his ebony skin glowing in the moon and his impressive cock for someone that looked like a high school student.
"We have agreed to call YOU the Alpha as you had the courage to be the middle bear first last night." One of them said. "I will be Beta and he..." Beta motioned to the third one, "...would like to be Delta." The young boy behind Delta seemed to be shaking, but it did not matter to you.
"Fair enough, but what is the boy doing here?" you ask in a rich and deep voice.
"Didn't you do this? It's initiation. In any anthro- cult, in order to make a new member part of the cult, it is practiced as 'The seed of three will make you me.' He wants to become a Werebear." Delta said. You must've joined the cult after wearing that jockstrap, but there was no initiation, unless the jockstrap did it for you?
"We're wasting time. Not to be selfish, but if we want a good orgasm and help this young cub, we're going to need a lot of time." Beta said. "Young cub, step onto that rock over there. You are to witness our sexual process and simply observe. However, you need to have sex with each of us in order to collect our seed. If I were you, I would get ready."
The black young man watched the environment, picked up a smooth stick, and then made his way to the rock. He placed the stick up his ass and began to stretch it out.
"That's going to be a massive hole for him to take us," you say.
"It will not matter. The initiation will heal him or kill him. That is the way," Beta said. "Now, Alpha, you are in command."
You're first action is to have both of them kneel. You slap each of them with your dick and slide it into Delta's mouth. As he begins to suck on your monster cock, you can feel it swell to an exponential proportion. Delta's mouth can hald a good foot of your cock, but another raw 16" is still in the open air. Beta begins to rise and soits on your cock, rubbing it with his massive hands. He makes his way around you, moaning a soft "kneel" to you now. As you get down, Delta begins using his own hands to rub your cock and even manages to fondle your balls. Beta's cock is fired up and you position yoursef just right to take his cock. His warm cock spreads apart your ass and begins its journey into your body. On the outside, he just keeps sliding his dick inside, pushing over 18" inside of you. Inside, it feels like his cock is going to push out your mouth, but you know his cock isn't that big, especially not bigger than yours. You keep this position for a good 20 minutes, helping Delta rub his own cock and Beta having rubbed your ass raw with all the effort he's put into you. Beta pulls out, but instead of switching roles, he walks over to the black boy, picks him up with ease, and ejaculates entirely inside of his ass. Beta only managed to get his cock tip in, but it was enough. The Omega sat there, a little precum dripping from his own cock. "Beta said this would take hours, but he's done in 20 minutes? Weak." However, you can feel an orgasm climbing. You gently push Delta away and make your way to the black boy. His ass is tight, but with enough effort your cock head fits in and you climax to orgasm. Loads of cum pour out of your dick and into this boy. Even he is having an orgasm, but his load is hysterical compared to yours. After 5 minutes if wildly bucking your hips, you finally finish and turn back to the other bears. Beta is taking Delta's cock as far as possible and Delta's balls are constantly smacking Beta's thighs. You come behind Delta and push your cock into his warm, surprisingly tight ass. His muscles make it all the more better and you somehow orgasm again inside Delta, but you also see remains kf Beta's second orgasm. After 5 minutes of raw fucking, Delta gets up and enters the young cub. You and Beta suck each other off, managing to climax a third time before getting up and watching the young cub. He sits there in the moonlight, tired and pale for someone with dark skin.
"Give him time. It's going to occur closer to moonset... If it works." Beta said. Beta looked at you suggestively, and all three of you bears went back to making love.
By around 4:30, the young cub began to stir. His muscles grew outwards along with every other body feature. His cock grew to an erect 21," but his balls were actually making you jealous. His muscles matched the three idle bears and hair sprouted all over. The Omega had pubes like a bush and thighs like tree trunks. His face was a fantastic chisel and he was overall an astounding man. As he came to, his cock surged up and nearly a gallon of cum shot out, splattering at the edge of the clearing.
"Welcome, Omega, to our little pack!" Beta said.
"I will not be your Omega. I will be the Black Bear. I think it's fitting.
"Well, Black Bear, would you like to make love to me?" you ask. Beta and Delta backed off on their own and the Black Bear took your cock, turned around, and put his ass right in front of your cock. As you enter, you feel like his ass is much tighter than the others and within 10 minutes, you've climaxed inside him. As you're panting for air, he comes around and whispers, "my turn," and the pushes inside of you as soon as he can. It's a sharper pain than usual, but within moments you're already feeling like you could orgasm again. His chocolate skin mounted on your back as he continually thrusts into you makes your cock ache for attention. On your hands and knees, you reach your head down to suck yourself. 20 minutes later, you've managed to climax twice more, and the Black Bear's strokes are increasing in pace. In seconds, he's bucking his hips and lets out an intense moan as gallons of semen rush inside of you.
By 6:00, all four of you have composed yourselves, the three others wearing towels while you wear an jockstrap with an impressive bulge. You head back to your dorm, but enter the showers instead. Inside, you shrink back down to your regular bear nature and all of Black Bear's cum drips out of your ass and into the drain. You jack yourself off one last time, but nothing conpares to the ecstasy of being with the other bears. What happens now?
