Reward?

As Anna ran she saw a man with a ringing phone and he waved her over. Blushing hard she came over.

"For you my dear" he said with a smile. She picked up the phone.

"Well done Anna, we didn't know if you would be a good girl this time or not but you pleasently surprised us. For that there must be a reward." The phone clicked. She wondered what it was.

"Best be going now, your reward will be given to you on your streak" said the man. She continued her embarressing run. Suddenly she felt a buzz. This must be her reward. 5 quick buzzes hit her and she wanted to release herself but she was no going to let in the thoughts. More buzzes came and so did she. The picture over her crotch was getting heavier and she felt herself cum onto it.
