She stops him

Not wanting to give James too much fun, you chuckle as Amy suddenly steps back, only one button now holding her shirt closed, hanging open enough that her cleavage and pink bra are on full display.

"Oh no Jimmy," Amy laughs at him, not bothering to cover herself up, letting her shirt hang open a little bit and smiling as she spots James' cock twitching once more. "You're not getting to see the goods that easily."

She paused for a moment, taking a couple of steps towards him again, letting his erect cock poke against the hip of her jeans as she whispered in his ear. "Now you need to be punished..." she whispered slowly, "take off the shirt too."
