Doing your best to ignore the device giving your cock the most powerful working over you've ever known, you stagger towards the amused techno-nymph and drop to your knees.
"Are you going to beg? That won't help" she tells you, giggling.

"Oh.. alright.. yes.." she closes her eyes and tips back her head as you lick at her, on hand rubbing at a breast.
