By seducing her

Sophie: "Say... d'ya think I'm sexy?"

Musclewoman: "Umm..."

Sophie: "Like, I said that I'm gonna stop your crime spree and also look sexy while doing it. But you're the only one here besides myself, and I'd appreciate a second opinion. Hot or not?"

The woman looks you up and down, lips pursed in bewilderment. She notes every little detail about you, and comes to the conclusion that yes, despite her own subjective preferences regarding women or athromorphic creatures, you are sexy in a universal objective manner.

Your face is symmetrical, well-proportioned and framed almost perfectly by the luscious locks of shiny lightly curled brown hair. You have mystical, large, unnaturaly light-green eyes that stare inquisitively, yet unintrusively. You exhibit an hourglass figure unlike anyone: wide, round hips and perky, almost softball-sized boobs hanging carefreely over your valleys of abs. The way you've cocked your hips and loosely hang one paw onto your waist while leaning your weight on a single leg while idly swinging your tail back and forth, is the epitome of casual sexiness.

Musclewoman: "Uhhh... Bl-..."

That went way easier than you expected. You waltz up to her and wave a hand in front of her face.

Sophie: "Hel-looo?"

She's completely entranced, staring shamelessly into your cleavage.

Sophie: "I guess you won't mind if I do... this?"

You lean forwards a little and start fingering the woman's already dripping vagina. Goosebumps caress her body as a droplet of drool forms in the corner of her mouth. You try out your claws for a moment - this woman's skin feels just about impenetrable - it'll probaby just feel nasty to her, but you're in a teasing mood.

No, her reaction seems positive! Her leg starts spasming up and down like the hindleg of a dog being petted. Time to amp things up, then! You start to fondle her bowling-ball-boobs with your other hand, and lightly fondle her lower back with your tail. From what Dr. Coitus told you, a person with Muscular Hypertrophy should have such dense muscles that their flesh would feel like steel to a normal human. You knew that your transformation made you strong, but apparently much more so than you expected.

The woman is molten wax in your tender care. Appropriately enough, she soon faints from overstimulation, accompanied by a carnival of orgasms. Judging by the way her body keeps jolting even while ****, she must be having a lot of them. You decide to jot this down as a win and head towards your next target.
