She uncovers

Biting her lip, Naomi slowly removed her hand from between her legs, spreading them a little, suddenly giving Tim a full view of her pussy, and the soft mound if pubic hair around it.

The display had the desired effect. Once again Tim's hand started stroking his cock, faster than before, his eyes constantly moving from her breasts to her pussy and back again.

Naomi felt her heart flutter. This boy whom she'd barely thought about before was openly masturbating over her naked body. If someone had told her this morning that Tim had jerked off thinking of her she'd probably have been disgusted, but sat here, watching him do it, she couldn't help but feel more and more aroused.
