My sub had been distracted all day. She had been told to read her task on the bus when she finished work. She knew that she was to find a seat and take her coat off to cover her lap and unbutton her trousers. John had been specific. It didn’t matter if she was in a seat on her own or if someone sat next to her, she was his owned slut and she needed to taste her juices and cum for him. She had already removed her coat as she boarded the bus. She moved to an empty seat and undid her trousers as instructed. Her clit was already throbbing and her plug was sitting deep in her arse. She knew she had to suck two of her fingers and put them covered in her spit into her wet cunt. Her nipples were like bullets as she shuffled over. Her heart leapt as a man with a shopping bag moved towards her and took the seat next to her. She knew everything about her was screaming stop but that John would order her to complete her task and tell her not to be ashamed of her sexual appetite. She could feel his leg resting against hers as she gradually eased hers apart. She coyly put 2 fingers in her mouth sucking them and trying not to look at him and then snuck her hand down under her coat. Her heart was racing but she stared straight ahead and moved her fingers into her open trousers to her already sopping cunt. She eased her legs apart further resting one leg on his and slid 2 fingers into her cunt. They squelched making an obvious sound as she worked them in and out. She could sense his presence but had been told not to stop whatever happened until she came. She was aware that the coat was moving slightly as she thrust them in and out but was getting close to orgasm and starting to care only about that.
