After awhile, Ty elbowed Dustin and pointed at the bench. A new boy had sat down. Ty wished to know his age and was surprised to hear that the boy was only 13, he was fairly tall for his age at 5'8", and dressed in jeans and a t-shirt, fairly casual attire. This was going to be fun, Ty thought.
The boy sat down and pulled out his phone, absentmindedly scrolling through his social media feeds. "What size should we give him?" Ty asked Dustin. "Big but not too big?" Dustin shrugged, "Max I'd give is 7 inches soft". Ty nodded and silently wished for the boy to grow to seven soft inches.
“Uhhhhmmm” the boy moaned softly, as his cock began to get longer, coiling and thickening in his jockstrap. The boy's balls also started to steadily inflate, growing larger and larger as well. Dustin nudged Ty and nodded. Ty focused in and saw that the denim in the boy's crotch was beginning to slowly fill out. The boy felt increased tightness in his jock as a result, but ignored it for his phone.
As Dustin and Ty continued to watch, the boy's crotch continued to slowly expand. "Ohhhhhhhhh" the boy moaned as the pressure continued to increase in his now-strained jock. Gleefully Ty watched as a "bubble" formed in the boy's crotch. Finally, the growth ceased and the boy was left with a seven inch cock and balls the size of eggs. Together, they formed a fairly noticeable bulge in the boy's jeans.
Just in time too, the boy put away his phone and stood up, headed elsewhere in the mall. Ty watched him go, cute bulge bubble and all. As a last parting gift, he wished that the boy would have a cute bubble butt and watched as the jeans filled out just that much back there.
