Gavin Holt is invited to a private California mansion for what he believes is a high-paying medical study. Two brilliant female doctors inject him with a mysterious compound and then put him through a series of intensely intimate tests. Only after the first orgasm does he learn the truth: the serum is activated by climax, and every time he grows. What begins as a controlled experiment quickly escalates as Gavin is pushed from normal size toward nine feet, then twelve, while the doctors continue to study—and thoroughly enjoy—every inch of his expanding body.


A focused, high-heat male-growth novella of scientific curiosity, progressive enlargement, and relentless sexual stimulation.
