Ken decided to look at the results of his work outside. He in a shadow on a side porch with a view on the street. He had taken the book with him in a bag together with some snacks. It was quite sunny and plenty of young girls and women passed by. Ken saw a few nice looking lactating breasts but was disappointed by a lot of them and even mildly disgusted by some. First he noted a few breasts that were simply too saggy and lacking in volume with nipples pointing straight down or in one case even seemingly poking the woman's torso . He opened the book and wrote down "A woman's breasts always protrude at least 67% of their height and do not sag with age. Nipples always point forward or upwards." He then stared at another woman with areola covering almost all of her breast making them look like they were infected. "Areola never cover more than 9% of a woman's breasts." He then saw a group of very small chested girls together with a girl who was lactating despite having no chest volume at all. "The average female cup size is D and the difference between cup sizes is one inch instead of one centimetre. Breast size is not dependent on height. A woman's lactation is dependent on breast mass with the smallest cup size barely ever lactate." He looked around increasingly horny. Indeed the look on the street had improved. His slowly increasingly straining pants could attest that. He was a bit disappointed with the bouncing of the breasts on the street. "Women's breast are very bouncy it is thought this is to entice men." Ken's dick was now diamonds as he looked across the bouncy lactating delights in front of him. Just as he put the book away and pondered satisfying himself in the shade of the porch he heard someone approaching. He looked around the corner and saw his new and improved sister Veronica. Her larger breasts looked almost desirable if only they weren't attached to his sister.
"What were you doing here?" She asked
Ken shrugged. "Eating some snacks, enjoying the weather."
His sister winced then pointed. "I can see what you were doing."
Ken realized she had seen his remaining erection.
"Don't jerk off to random girls on the street with that tiny thing. "
Ken opened his mouth but before he could say anything she continued.
"What if my friends saw you? Think about my reputation. Get inside."
Ken grabbed his bag and held it in front of his still lasting erection.
Veronica rolled her eyes "Nobody is going to notice your tiny hard on from the street."
Once inside Ken went upstairs to his room...
