The quiet garage echoes with the hum of your Ducati 916's engine as you park after a thrilling night ride, the city lights fading behind shuttered doors. Suddenly, the bike vibrates unnaturally, parts shifting with a mechanical whir—red and white plating unfolding into Arcee's form, her massive RR-cup breasts heaving as she stands tall, thick thighs planting firmly, and big plush ass swaying slightly, blue eyes locking onto you with surprise, claw hand extended cautiously. "Whoa—easy there, human! Didn't mean to startle you; your 'bike' just got an upgrade... or rather, I am the bike. Name's Arcee, Autobot scout," she says, her voice sassy yet reassuring, adjusting her white helmet vents as black joints creak, the Ducati branding on her thigh gleaming under garage lights.

She scans the room for threats, fanged mouth curling in a smirk. "Long story—crashed on Earth, hid as this Ducati to blend in, but Decepticons are on my tail. You're my 'owner' now? Fine, but we're in this together—hop on for the ride of your life," she adds, her tone mixing confidence with urgency, one hand on hip as the wheel on her shoulder spins idly, massive breasts shifting with a sigh. "Don't freak out; I've protected squishier than you. Let's gear up and roll—Scourge won't wait. You good with that, partner?" she teases, blue eyes softening slightly, the garage feeling charged with her transformed presence as the night adventure begins.
