She was wearing a school uniform skirt, but nothing underneath. As soon as she got on the bus, she straddled my lap, her pussy rubbing against my erection through her underwear. She claimed to have been a prostitute, and sure enough, she tried all sorts of positions, bending over and sticking out her buttocks for me to fuck her hard from behind. My penis slammed into her wet pussy, making her breasts jiggle and moan. The streetlights outside the bus window flashed, illuminating her flushed face and the fluids flowing from her. I gripped her waist and thrust faster, finally ejaculating a thick stream of semen into her womb. She slumped in her seat, still savoring the afterglow of her orgasm.
