She watches

Keeping her hand covering her pussy, but knowing only too well that every other inch of her body was on display to him, she licked her lips for a moment, looking him in the eye once more and nodding.

Tim understood the unspoken command, and also instantly began stroking his hand back and forth along the length of his shaft once more with far more speed than previously.

Naomi felt her breath quicken as she watched. She'd seen this sort of thing in porn before, but to know there was a boy, just a few feet away, jerking off while staring at her body sent feelings of pleasure through her. The had covering her pussy could already feel the dampness between her legs, and for a moment she worried that she was leaving a puddle on the floor. Part of her wanted to check, but she couldn't keep her eyes off the cock in front of her, Tim's hand stroking back and forth, faster and faster, clearly nearing a crescendo.
