She trembled a little as she felt his breath against her neck, "Good girl." Becki melted a little at his words as she felt his fingers slip beneath the fabric of her underwear. At that moment, she stopped thinking about the call going on in the background and let herself focus on the pleasure building within her at every stroke of his skilled fingers.
As he slipped his fingers inside her, Becki's inevitable moan was stifled by Rex's hand over her mouth. Becki glanced at his face and saw him trying to stifle a laugh. He kept his hand over her mouth as he continued fingering her steadily. Becki's breathing quickened as he bought her closer to the edge.
Without warning he stopped, his fingers stilled within her as he answered a question that had been directed at him. Becki whimpered against the palm of his hand and tried to move her hips against him, but he was too focussed on the conversation he was having. Needing to release the pressure he had built up inside of her, she slipped her own hand into her underwear and stroked the back of his hand with her fingers.
She felt his fingers resume their previous rhythm, quickly bringing her back to the edge. Becki kept her hand over his and pressed the heel of his hand against her clit. She struggled to stay quiet as her orgasm pulsed through her, her hand pressing Rex's against her until she was done.
Rex ran his tongue quickly across her neck, before unhooking her ankle from the chair. Becki slid off of his lap and straightened herself up, watching as Rex casually sucked his fingers clean as he continued listening to the call.
