Your eyes widen in shock as Kappa begins moving toward Dale. But shock turns to horror as Kappa's eyes meet yours, and he suddenly stops short.
The members of his tribe begin murmuring to each other. "Our god chooses yours first!" one of them cries to your tribespeople. You try to protest, but you cannot speak. "Very well" the leader of your tribe says, and as he points at you with a strange wand you fall to your knees, helpless and terrified, as Kappa strides forward. His dick hardens to a freakish eleven inches by the time he reaches you, and without warning he plunges the whole thing into your open mouth. Your mind revolts, but your body can't help but suck viciously at his cock, until, very quickly, torrents of cum start pouring down your throat.
After a few seconds you expect it to let up, but then discover that Kappa is still spurting cum into your mouth! But still you cannot move, and remain perfectly still on your knees, receiving the endless stream of semen.
Then a strange feeling comes over you. As the cum continues to go down your throat, you feel a burning sensation in your knees. You fidget a bit in your kneeling position as your calves and quads seem to grow larger, thicker. Sensing your movement, Kappa backs away from you with a smirk, his dick still dripping. You stagger to your feet, but as you do, the burning sensation spreads over your whole body. You feel muscles shifting, tendons straining. As you choke and gasp for breath, you look down at yourself, and watch in disbelief as your legs become huge trunks of muscle the size of bodybuilders'. Your torso follows suit--your waist narrowing, your stomach flattening with a perfectly chiseled set of abs emerging, and your pecs inflating into enormous globes on your chest.
You hear your tribesmen muttering as the changes progress. "Look how quickly he grows!" one of them shouts. "He is the chosen one!" They stare in awe at you as, confused, you watch your upper arms swell to the size of canteloupes, your lower arms doubling in thickness, and feel your back expanding into a vast v-shape. Finally you manage to walk back to the pool where you saw yourself earlier. Looking back is the hugest, most attractive, and most muscular man you have ever seen.
