The clock ticks down, 40 seconds left until the high wears off. She's got his cock in her mouth, swirling her tongue around the head, tasting the salty pre-cum. He groans, fisting her hair, thrusting his hips to meet her eager mouth. She takes him deep, her lips stretching to accommodate his size. They're both racing against time, their bodies tensing as they climb towards release. With a final, desperate suck, she pulls back, straddling him, impaling herself on his cock. They fuck frantically, their bodies glistening with sweat, until they both explode, their cries of pleasure echoing in the small room.
