In the dimly lit, secluded gloryhole booth, a skilled sucker awaits, her eyes fixed on the thin partition that separates her from the unknown. As a thick, veiny cock pushes through the hole, she feels a surge of excitement. She leans in, her tongue flicking out to lick the underside of the shaft, tracing the sensitive vein that runs along its length. She takes her time, exploring every inch with her mouth, her tongue, her lips. She can feel the cock pulsing in her mouth, growing harder with each passing moment. She knows she's doing something right when she hears the soft moans coming from the other side of the wall, encouraging her to continue her oral onslaught.
