"That could be useful" Loki smiled as he freeze the time. He took the dart and fused its energy with his powers.
"Why did you do that?" Thomas asked bewildered.
"Highly concentrated testosterone and nordic magic." Loki said. "I will give you a sneak peek of what that can do."
Loki shot an energy beam from his hand toward Thomas who fell from his chair. When he got up again, he wasn't a twinky boy anymore.
"I'll call it bara-magic." Loki grinned when he saw Thomas' new look.
"Bara-magic?!" Thomas replied but he stopped when he realized his voice was deeper. He touched his neck and noticed a prominent Adams apple and sturdy and rough neck. He looked at his hands and saw that they were bigger and calloused like lumberjack hands. "Why did you do to me?!"
"Haven't you heard about bara?" Loki said as he put a hand over Thomas' new strong arm, so full of muscles that ripped his sleeves. "I like bara media with speedoes. So, I can see the goods better." He used his magic again and Thomas' ragged clothes vanished in the air left him with just his really stretched boxers. He tried to cover his nakedness with his hands but when they made contact with his groin he felt a sudden rush of arousal and he fell on his ass.
"OooOoohhh!" He moaned when he realized how big and plushy his butt felt. "I felt... Oooh.. weird" He moaned as he rubbed his sturdy legs. "I'm hairier and my feet... OooOohhh!" Loki just grinned. "Look how big my feet are! I'm a bigfoot!" He rubbed his soles, big and calloused like his hands. His dick was getting hard inside his too small boxers. He sniffed his toes and they stunk like a locker room. "I should be disgusted. Why am I so aroused? OooOohh!" He began to stroke his shaft over his boxers as the fabric magically became smaller and changed.
Loki was enjoying while he watched how Thomas' dick became bigger under his new speedo. A perfect dick silhouette, thick like a soda bottle and over a foot long was clearly visible. Precum was sprouting wildly from his fattened mushroom head making a mess on the floor and his new red speedo.
"Oooh!! I-I can't stop!" He shouted as he took his slippery dick out of the small fabric. He was vigorously jacking off without hesitation. "I'm... so... big..." He moaned as he quickly moved his left hand on his pole, 13 inches of pure meat. At the same time, he flexed his right arm, exposing his bulky biceps and his astounding amount of armpit hair. He sniffed them and, although he has a disgusted face at first, he licked them and sniffed them again several times.
After some intense minutes of jacking off and his sturdy new body completely covered in musky sweat, Thomas shot his load directly to the muscle mountains in his chest. He shot once again and again, and with each load his balls grew fatter until they looked like softballs inside his tight red speedo. At the end, all his body was covered in so much cum and sweat that he alone reeked like an orgy.
"That was a good bara demonstration." Loki grinned. "Did you enjoy it?"
"I'm so disgusting, but... I'm... still... so... horny" Thomas babbled. "I... need... MORE!!" And he began to stroke his shaft again.
"Calm down, tiger!" Loki laughed. "What you need are playmates..." He wickedly smiled as he looked at the TV. "And I know where to find them."
