An Asian family next caught his attention, and David had to mess with them a little too. The father was about 5'9", average build and had short dark hair and glasses, he wore a blue polo shirt and beige pants with black shoes. His wife was just 5'3" tall, not too curvy and her breasts were on the small side, about a small B-cup. She had her hair down and wore a floral-print dress and white sandals The couple's two kids, a boy aged 15 and a girl aged 13 were waiting for the car to be unlocked, and both were on their phones. "What is it with kids and their phones?" David tutted, smirking as he first focused on the mother and her son.
A quick thought later and their heads had been swapped. The mother now had her son's teenage body and vice-versa. The boy adjusted his bra strap and then took his phone back off his mother, mumbling something in their native language. The mother responded in a slightly harsher tone, clearly not appreciating the tone with which her son had spoken to her. They remained oblivious of their swapped state, as David knew they would.
Switching his focus now to the father and his 13 year old daughter, David swapped their genitals, watching with delight as the girl's white capri pants slowly inflated in front with her father's junk. As a result of the swap, the girl's penis instantly got hard and her bulge grew slightly bigger, causing her to adjust her stance as she continued texting on her phone. In fact... her new member was as hard as David's was. David remained silent, and watched a short exchange of words between father and daughter, paying particular notice to the man's deflated pants and knowing he now had his young daughter's horny pussy nestled between his legs. "Enjoy!" David chuckled, giving his own boner a rub before moving on and letting the family drive off in their car.
His own arousal growing, David quickly targeted the next people he saw as well. A mid 20's couple, clearly in a relationship, walking down the street discussing something. The woman, who was fairly pretty, had her red t-shirt fall limp against her chest as her C-cup breasts melted away, leaving her boyfriend's small nipples and hairy chest in their place. Meanwhile, her boyfriend's t-shirt pushed out handsomely as his new boobs sprouted from his chest... but lacking the bra that his girlfriend was still wearing. David didn't bother swapping the garment over and instead he laughed as he watched the man's tits jiggle free under his t-shirt. "God I love doing this." David said, biting his lip and feeling his dick twitch again in excitement.
