If I'm on a crowded bus and end up sitting next to a girl in a miniskirt, her ass pressed against me, I'll get hard. My erect dick lifts up her miniskirt, exposing her panties completely. The girl, realizing this, blushes with embarrassment as she desperately tries to pull down her skirt, but her hand touches my erect dick, igniting both of our desires. My bare dick presses into the crack of her ass, and to avoid being noticed by other passengers, I insert it into her vagina.
