David was thoroughly enjoying himself at this point as more people kept appearing, as though asking to be swapped. Two good looking young, brunette women in their early 20's, both wearing different colored skinny jeans and tight tops were walking down the street in David's direction, chatting to each other. Close by, in a back yard, two 12-year old boys were playing with a soccer ball. A click of David's fingers and both women sprouted pre-teen cocks in their jeans, creating small bulges. But then David noticed their bulges swelling in size as both women got erections. Apparently the swap had triggered the onset of puberty for both sets of genitals, and male hormones began flowing through the women's sexy bodies... which would in the next couple of years begin developing body and facial hair, and their voices would drop in pitch too. Both would be well hung in a few years.
Meanwhile in the back yard, both pre-teen boys were now the owners of adult vaginas, their shorts deflated in front, and one of them was chagrined to discover he was on his period. "Sorry dude, I gotta go put a tampon in, I think I'm bleeding." The fair haired boy grumbled to his brown haired friend, as he rubbed his abdomen.
"Its okay dude, I got you. I had my period two weeks ago." His friend replied, understanding.
Tears in his eyes from laughing so much, David wiped them away and continued down the street. His next victims were a father and daughter pair, 40 and 22 years old respectively. "Lets try... this." David smirked, making a cross-over motion with his fingers. The father's and daughter's bodies were swapped from the waist down. The man lost several inches of height as he gained his daughter's shorter, sexy legs, pert ass and dainty feet, not to mention her pussy. And his plaid shirt now clashed horribly with the tight black leggings and women's tennis shoes that his lower half was now wearing. The daughter's upper half now sat on her dad's muscular, hairy legs, and her beige corderoy pants were bulged out in front by her new penis. Oh that was a good one. David moaned, rubbing his own dick through his jeans. But then he clicked his fingers again and reswapped their genitals, giving the daughter her vagina back, and a large bulge appeared in the father's leggings as his 7-inch cock appeared back between his now feminine legs.
He kept moving down the street, swapping as he went.
