Ace Bigs and Daya Dare, two insatiable coworkers, find themselves alone on a long, empty bus ride back from a construction site. Ace, a seasoned engineer, can't help but notice Daya's curves, accentuated by her tight, grease-stained overalls. Daya, feeling Ace's gaze, playfully winks and spreads her legs, revealing a tantalizing glimpse of her black lace panties. Ace, unable to resist, approaches her, his hard-on tenting his pants. He leans in, whispering, "Let's measure something more interesting." Daya grins, "I thought you'd never ask." They disappear into the back of the bus, leaving a trail of discarded clothes and a symphony of moans echoing through the empty vehicle.
