Summary: David Miller, deeply insecure about his 4cm erect micropenis, feels unworthy of his stunning girlfriend Anna, who has Complete Androgen Insensitivity Syndrome (CAIS): she is genetically XY, phenotypically female, tall, infertile, and has never had periods. Desperate to satisfy her after months of failed intimacy, David visits a shady private lab run by Dr. Harlan and signs a liability waiver for an experimental synthetic testosterone cream. He over-applies it, causing his penis to grow dramatically to over 20cm, along with increased muscle mass. During their passionate reunion sex, residual cream transfers to Anna, triggering her rapid, uncontrollable growth: she becomes massively taller, stronger, and more dominant, with swelling breasts, hips, and limbs. She flips their dynamic, rides him with raw power, and experiences her first intense orgasm with him before collapsing in loving ecstasy.
