All alone in the basement

Sophie slips down to the basement when the rest of the building is busy. She wants a quick, private orgasm, and the cool stone walls keep it secret. Her body is hot, the floor is cold, and the contrast makes her shiver. She pulls the lace of her lingerie aside and presses the vibrator against her clit. The first slow buzz makes her thighs tense. She spreads her knees wider on the hard floor and tilts her hips forward, grinding into the toy. The stone carries every sound back to her; a soft gasp bounces off the walls like a louder moan. She turns the speed higher and her breath catches. Her free hand slips under the bra, squeezing a nipple until it stands stiff. Sweat starts to bead between her breasts, sliding down her stomach. She rocks faster, chasing the throb, and the vibrator slips slickly over swollen flesh. A sharp cry escapes her, echoes twice, then fades. Her legs shake, heels skidding on the floor. She keeps the toy in place through the first wave, then eases it off as the second tremor hits, softer, leaving her panting and flushed against the chill wall.
