She looked up to see his gaze locked on her fingers teasing her pussy. “You like watching?” she asked between rapid breaths. He nodded, white curl... bouncing. She rubbed faster – wet, squishy sounds reaching her ears as her labia slipped over each other, well lubricated with her juices. He smiled, and she could feel him throbbing even harder in her ass. Her willpower finally won out as he watched her masturbate. “More,” she said in an explosion of breath, and then thrust two fingers deep into.

Instinctively her legs open wider and my firm wet. “Here, let me help you” At Aarons touch the girl gasped softly. She jerked and stared at him, her eyes burning with a deep lust. Aaron could clearly see her nipples harden again and saw the wet patch between her legs noticeable against the grey fabric. “Um...thanks” Her voice had changed, becoming slightly more husky “I think I've hurt my leg, I've got a bit of muscle spray in my bag though.” “No worries, I’ll grab it for you” Aaron stood and began looking around her treadmill.“No no, it's in. Today she had just found out that the guy she had been seeing a couple of times had only a temporary assignment here, and that he had a family elsewhere.

She really had a temper - and her marriage had not been an easy one. She had been married to a policeman who was.
