She stops... distracting Kevin, that is.

With a sigh, Max straightened up in her seat and stopped distracting the driver. It was probably a bad idea anyway.

She pressed her thighs together as she stared out of the window. She needed to get her mind out of the gutter, but teasing Kevin had turned her on more than she had expected.

She reached down and pulled her bag into her lap, so that she could slip a hand beneath her skirt without Kevin noticing. She bit her lip to suppress a gasp as her fingers found her pussy lips swollen against the material of her thong. Turning Kevin on had made her so wet.

She pushed aside the crotch of her panties and ran her middle finger along her slit, feeling her juices coat her hand. Fuck, it felt good.

She leant back in the car seat and moved her finger over her clit, first teasing herself with gentle circles around the nub, and then moving to faster flicks. She glanced over at Kevin, but he was concentrating on the road and didn't notice her gaze. She shifted in her seat, parting her legs so that she could grind against her palm. She tried to control her breathing, but felt herself losing control. She desperately wanted to push her fingers inside herself, wanted to feel herself cumming all over Kevin's car-seat…

Looking up, she noticed they were a minute away from the school-gates.
