Office Harassment Caught On Tape

I am troubled by my superior's consistent inappropriate behavior towards me at the workplace. He persistently makes unwelcome advances, yet no one, not even the human resources department, believes my complaints. He continuously portrays excessive kindness, which I see through as a guise to engage in unwanted sexual activities.
Despite my constant refusal, he regularly suggests giving me massages, an offer I always decline. I yearn for these advancements to cease, but I ask myself, what can I possibly do to make it stop? Since the human resources department offered no resolution, I discretely installed surveillance cameras at the office in hopes of capturing the creepy behavior on tape. Fortunately, my plan bore fruition! The footage reveals every detail, from his sly approach to the explicit propositions he makes.
To gather sufficient evidence, I had no choice but to reluctantly agree to a massage, enduring discomfort as he laid his hands upon my shoulders. When his touch enhanced to the point of reaching my most intimate body parts, I had to summon all my strength to remain composed and comply. I couldn't take the risk of arousing suspicion.
Now that I have tangible proof of his misconduct, I anticipate that my ordeal will finally be acknowledged by everyone.
