*****
It was a normal Saturday afternoon, and Hannah went into town to do some shopping. She needed a few things for the house, like soap and sponges. She was wandering down the street when she noticed a man walking the other way. Her eyes automatically looked downwards to his crotch. He had a bulge there. She saw him look over his shoulder after he passed her, and then keep on walking. Hannah guessed the man had just checked out her ass. This made her feel less guilty about checking out his package. She turned and began to follow him at a distance. He stopped and entered a store.
Hannah paused for a minute and then went into the same store, being careful not to be spotted. She took a small mirror out of her handbag, and angled it in such a way that she could see him without him seeing her. The bulge in his trousers had diminished a little, and she wondered why. No matter, it was something she could probably remedy. She stowed her mirror and tucked the back of her shirt into her tight leggings. This had two effects. First the shape of her ass was now showing, and second, her top had tightened over her chest and given her a deep cleavage.
She giggled quietly to herself as she nonchalantly strolled past him, making sure to ignore him and focus on the products in the store. At a suitable point she bent slightly at the hips to ensure her ass was pushed out towards him. She knew this would ensure his cock was as hard and big as possible. It worked. She could almost feel him looking at her as she stood straight again. Hannah made sure her ass was swaying sensuously from side to side as she walked around the store. She glanced at him from the corner of her eye and saw his eyes were fixed on her ass. She hoped she had done enough as she was about to turn the tables. She ducked into another aisle and spun around to face back the other way. Hannah knew the guy would try to casually walk into this aisle and get another look, but now he was unable to stare directly at her as she would be facing him.
Right on cue, the man wandered around the corner and immediately became very interested in some cups for sale so as to avoid being suspicious. His face was away from her, and Hannah had positioned herself in such a way that she could freely look in his direction without him seeing her looking. Her eyes searched hungrily for his bulge.
She looked down and saw that he was no longer wearing his belt. She wondered why he had done that. Perhaps to allow his pants to hang lower? Hannah soon found out why. His cock had swelled in size since she last saw it, and was now a truly impressive bulge. Hannah licked her lips as she watched his erection grow.
