Give her a shock!

CRACK!

The electrical shock within her clit sends her rocketing off of her belly and onto her knees. Instinctually she stuffs her hand into the folds between her legs. Her hand cradles her vibrating bud attempting to protect it from the unseen attack. But there is not protection from the device within her.

You tisk disapprovingly.

Her eyes grow wide in fear as she realizes her mistake. Her hands rapidly return to you dick and she shuffles back to your dick to resume pleasing you. She sucks with more gusto than before. She understands the urgency with which she must work.

With a full mouth, her big blue eyes plead up at you for mercy as her head continues to bob at the end of your 12 inch manhood.
