As Brandon rubbed and rubbed against the giant cock, his own penis continued in stimulation. Tears fell down his face as Alex jostled him around on his erect penis. Brandon dwindled down, holding onto the flesh for dear life.
It was so warm though...and so large. Brandon found himself cradling it, his one salvation, keeping him away from the floor which loomed down, growing further and further away from him as he shrank.
Brandon was now barely bigger than the head of Alex's penis, but his miniscule body kept rubbing against it. He head Alex's breathing grow louder, and soft moans escape from the bigger boy.
There was another moan that rang out. Brandon realized only a few seconds later that the moan belonged to him. He was coming close, his penis was about ready to explode, and from the way Alex's body was rocking and dwindling, so was he!
Brandon found himself hugging the penis tighter, feeling it grow more manageable in his hands as Alex shrank. Alex stood around a foot tall by this point, while Brandon had shrunk down to microscopic proportions.
Alex gave a loud moan and suddenly exploded hot, sticky cum all over Brandon's face. Alex gave a yelp of surprise and pleasure. Brandon suddenly saw the floor grow closer to his face.
Within a few seconds, Alex's penis became smaller and smaller, while Brandon rubbed against the exploding member, as it shrank around him. He stumbled to the floor, sliding off of the bully's cock.
Brandon looked up and saw Alex quickly shrinking down to meet him. The giant shrank down to Brandon's size. Brandon stared eye to eye with the boy he'd just jerked off. A lump formed in both of their throats.
"I'm going to blame that all on the gas." Brandon growled, finally feeling in control of his situation.
Nervous, Alex nodded. He was still exhausted from his orgasm, and his bare chest beat up and down, covered in sweat. Brandon's whole body was still soaked in cum.
