The R6's powerful engine purrs like a beast in heat, its rider lost in a world of their own, the porn streaming on their phone providing visual stimulation. They kickstand the bike and lean back, one hand gripping the handlebar, the other delving into their pants, pulling out a stiff, throbbing cock. The rider's breath hitches as they stroke themselves, the bike's vibrations and the porn's explicit sounds pushing them closer to the brink. They imagine the woman on the screen riding them, her hips grinding, her breasts bouncing, as they pick up the pace, their grip tightening. With a final, shuddered breath, they come undone, their release mingling with the bike's exhaust, a taboo symphony of desire and machinery.
