Watch her work.

The private room is dim. You lean against the wall in the hallway, arms crossed, watching through the crack Gemma has left in the door. She saunters towards the plush velvet couch where the first customer waits - a young guy, tie loose, eyes glued on her body as she sways her hips, her slinky dress riding up her thighs. She straddles him without hesitation, her fingers working the buttons of his shirt as he groans, his hands gripping her waist. You watch as she frees his cock, her small hand wrapping around him, stroking him slowly before guiding him to her entrance. The way she sinks down onto him is mesmerizing - her tight little body swallowing him inch by inch.

Your cock hardens as she starts to move. The guy's hands are all over her, gripping her ass and breasts clumsily. You can tell he's inexperienced. She rides him steadily, her tiny frame bouncing on his lap, her tits jiggling with each movement. His head falls back, his mouth open in a silent groan as she fucks him.

The next customer approaches you in the hallway, and you wave him past with a nod. Another young guy, all cashed up. He pushes open the door, and waits patiently, his hand on his cock as he strokes himself, unable to look away. Gemma doesn't stop, but motions for the second kid to come in. She reaches for him as he enters, her fingers wrapping around his shaft, and pulls him closer before replacing her hand with her mouth. The first man just watches, his cock still buried inside of her as she gyrates in his lap and takes the newcomer in her mouth.

The first man finally cums, his body shuddering as Gemma continues to milk his orgasm out of him. After he's done, she climbs off him and turns her attention fully to the second, kneeling in front of him to take his length fully in her throat.

You stay right where you are, your eyes locked on her as you watch her work, your cock aching with desire.
