注射とトレーニングを繰り返すうちに、彼はもはや周囲の誰とも比べ物にならない体格へと変貌していた。筋肉の鎧をまとったような体を誇示するように鏡の前でポーズをとると、その顔は獰猛な笑みに歪む。かつて感じていた恐怖や不安は、今では昂ぶりを引き出す燃料となった。重量に押し潰されかける瞬間でさえ、心臓が跳ね、恍惚とした笑みがこぼれる。

そんなある日、友人に「ちょっと筋肉を見せてくれ」と言われる。彼はためらうことなく服を脱ぎ始め、上半身だけで済むと思った友人の期待を裏切り、ついには全裸になった。友人は呆気に取られる。逞しく盛り上がった胸板と分厚い腕。腹筋は岩のように割れ、脚は大樹の根のように張り出している。それだけでなく、下腹部には明らかに常人を逸脱した大きさの器官が存在し、異様な存在感を放っていた。彼はそんな視線を浴びて逆に昂ぶり、挑発的な笑みを浮かべる。

「……あ？　何言ってんだ。お前が脱げって言ったんだろ？」

その眼差しは理性の光を失い、獣のそれに近かった。クスリの作用で分泌され続けた超高濃度のテストステロンもろもろは、彼の脳さえも根本から作り変えてしまっていた。

• 性欲回路の変容：扁桃体と報酬系が直結し、性的刺激と暴力的昂揚が同じスイッチで入る。

• 衝動性の増加：前頭前野の抑制が弱まり、欲望が即行動へと転化する。

• 自己愛と誇示欲：他者に見られることでさらに興奮し、優越感が快楽そのものになる。

友人の驚きと沈黙すら、彼にとっては快感の燃料となった。常人なら羞恥と感じる状況を、彼は支配と優越の証として受け取り、さらに昂ぶっていく……。

As he continued with the cycle of injections and training, his body transformed into something far beyond comparison with anyone around him. When he struck poses before the mirror, showing off a physique like armor forged from muscle, his face twisted into a feral grin. The fear and anxiety he once felt had now become fuel that only heightened his arousal. Even in the moment of being nearly crushed under the weight, his heart would leap, and an ecstatic smile would break across his lips.

One day, a friend asked him, “Hey, show me your muscles for a second.” Without the slightest hesitation he began undressing. While the friend expected only his upper body, he went further, stripping completely naked. The friend was left speechless. His chest swelled powerfully, his arms thick and dense; his abdominals were carved like stone, and his legs spread outward like the roots of a great tree. And beyond all that, his lower body displayed an organ that had grown to a size clearly far beyond human norms, radiating an uncanny presence. Far from embarrassed, he grew even more excited under that gaze, his mouth curling into a provocative smile.

“…Hah? What are you talking about? You’re the one who told me to strip, right?”

His eyes had lost all trace of reason, now closer to those of a beast. The constant flood of ultra-high-dose testosterone unleashed by the drug had reshaped even his brain at its very core.

• Altered sexual circuitry: the amygdala and reward system had fused, making sexual arousal and violent exhilaration switch on together.

• Heightened impulsivity: the prefrontal cortex’s restraint had weakened, turning desire directly into action.

• Narcissism and exhibitionism: being watched only drove him into greater excitement, with superiority itself becoming a source of pleasure.

Even his friend’s shock and silence became fuel for his ecstasy. What would be shame to an ordinary man, he embraced as proof of dominance and superiority, which only pushed his arousal further and further…
