"No, this can't be!" Ken said, stopping mid-sentence when a wave easily pushed him nearer to shore. While the other men are groping their bodies with anticipation, Ken was trembling as he assessed the loss. His arms aren't that thick nor muscular but they are better than the new scrawny ones he got. He's not wearing any clothes so he could immediately see his flat childish torso with his cute pink nipples. His head is huge. Not as heavy as he thought it would be.
