The boys watches as Fransisco began to change. He grew taller, somewhat thicker, but not by much. The boys saw him as taller and a bit more muscular, but Mr. Mendes didn't seem to notice. He opened his eyes and looked back at the boys. "Kinda dazed out there guys.... what was I saying again?" The young boys looked at him and shrugged. Francisco suddenly remembered "Oh yes. You're supposed to go to the Hernandez' before soccer practice.. I've got to get you two over there." He began to hurry them out of the door, pulling the book from them "You'll have plenty of time to read that later, today you have soccer." He dropped it on the table as he ushered them out.
---------------------------------------------------------------------
Francisco returned home after dropping the boys off, still a little stiff from the morning run. He still didn't notice his altered size, even though he was only a few inches taller and a few pounds heavier. He saw the book on the table in front of him, wondering what was so interesting about the book that Ric and Josh were holding. The title was odd, a book of transformations... He opened the book and looked through, finding strange latin incantations. He understood one section as "Self".... what was that supposed to mean? As he always did, Francisco read aloud...
A small chant passed through his lips and he began to feel the wave of pleasure once again. Unknown to him, he was swelling. His stomach was expanding beneath his T-shirt, as well as his chest and arms. He suddenly felt his shirt stretching tightly across his expanding girth. He looked down at his once size 30 waist swelling well past 35. His shirt buttons began to pop off, revealing what was happening. His gut was round and firm, bulging out beneath pecs that grew more and more solid. He pulled off his shirt, as well as his pants as the tightened about his thighs. He stood in his living room in his boxers, swelling more and more. His ass began to fill their seat. His chest and biceps looked like a huge bodybuilder, so did his defined thighs and bubble butt, but his massive waistline betrayed that illusion. His waist had to be 60 inches around, maybe more! He wasn't stopping, and in a matter of moments, the boxers ripped from him, leaving him huge, nude, and still swelling.. He was trying to stop it, but he didn't know how... He uttered another latin word he remembered.
"Desino!" He said. He remembered that it meant stop, and it did. Francisco stood amongst the tattered remains of his clothes, more than 3 times his original weight when the door opened.
"Where are you, mi amante?" Came a cheery voice, in sauntered Marco. He caught one look at the fatter, more muscular Francisco. "What happened to you mi amante!?" He ran over, rubbing the bulging gut. "I don't know! I just read from the book on the table and started growing!" Marco picked it up and read from another section. He spoke some words, once catching Francisco's ear. "Auctus Genitalis.".
"Genitalis? What was that one about?" Francisco asked, feeling another surge. He looked down at his crotch, but couldn't see what was happening over his gut, but Marco had a front seat. Francisco's cock was swelling at an accelerated rate, but it wasn't getting hard. 3, 4, 5, 6 inches! It wasn't stopping , 8,9,10,11,12. It began to peek past his gut at 15 inches. 20 inches past quickly, and Francisco shouted once more "Desino!" The growth stopped, his pendulous cock swung at 25 inches from his crotch. Marco rubbed it affectionately. "I like this book amante!"
