She joins in

Watching as Tim stroked his cock for her, Naomi found she could no longer resist. Slowly she lowered her hands, lightly caressing her thighs, before gliding them up, slowly, until they reached her pussy. For a moment she spread her lips, feeling her cheeks flush as Tim's eyes focused on the pink skin of her pussy, before she buried two fingers deep into the folds.

She had to bite her lip, trying not to let out a moan of pleasure, the sounds of Miss Ogawa on the phone at the front of the room being drowned out by her own heartbeat in her ears.

While her fingers inspected every inch of her pussy, gliding in and out in time with Tim's own hand movements she bought her free hand upwards, cupping her breasts, playing across her firm nipples, drawing more and more waves of pleasure through her body.
