"Hey!" Ryan yelled embarrassed.
"Hehe, sorry." Vivian apologized. "It's just that I can't take this seriously with a boner as small as my little finger."
"Don't make fun of me!" Ryan yelled even more embarrassed than before. "Just wait I grow and you'll see I'll be bigger than Bradley!"
"That's what I'm expecting for." Vivian replied while she started to undress.
Ryan has his sight focused on her big bosom as she took off her bra. It was the first time he saw tits in real life. They looked so firm and puffy that he felt like a baby desiring to lick them.
"Oh, that's all?!" Vivian smirked when he saw a drop of white goo coming out from Ryan's dick. "You had no endurance at all!!"
Ryan didn't say anything, he was so ashamed to give a reply. However, at the door, there was someone else staring at the scene.
"I don't know what's going but please don't stop, Viv." Bradley said as he got closer to the bed where Vivian and Ryan were trying to intimate.
"Bradley!" Vivian cried in surprise and she tried to cover her breasts. However, when Bradley was close to her, she noted the tenting bulge in his blue boxers and she got a wicked idea. "Hey, why don't you join us? There's a spot in the bed next to Ryan."
"Wonderful." Bradley said in a seductive male deepness that chilled both Ryan and Vivian.
Bradley sat next to his friend and Ryan could realize the big gap between him and his friend. Bradley wasn't just older now, he was obviously way more taller and stronger than him, he could see a nice rough skin with fit muscles and the perfect amount of body hair to look manly but not bearish. He also can smell an intoxicating smell emanating from him, mix of musk and sweat coming out from his pores.
When he looked down at his legs, Ryan felt ashamed of how thin his own legs were in comparison. It wasn't just muscles and hair, but Bradley's legs were longer than his now. Ryan's size 8 feet looked pathetic next to Bradley's size 14, even his fat childish toes were no match against Bradley's lean and manly ones, plus his delightfully arched soles.
"May I?" Vivian purred as she put her hands on Bradley's thin boxers. He didn't answer just grinned while she slowly slid them off to his knees.
Bradley's manhood jumped like a spring until it pointed to the sky. Ryan who was still naked from his waist down felt pathetic of his own 2 inches boner when he saw the 10 inches monster in Bradley's groin. It was thick as a soda can and full of hirsute hairs that made Ryan felt even more ashamed. Besides, Bradley was uncut and was sporting a shiny bulbous pink dick head when his foreskin moved back in contrast with his circumcised shame.
"That's a good dick!" Vivian smiled before she put her hands on his shaft and started to stroke it. "Do you like it, big boy?"
"Oh, yes! Please, don't stop!" Bradley groaned in his sexy manly voice while he was squeezing Vivian's butt cheeks.
In no time, they were making sex passionately in front of Ryan who felt humiliated that his friend who was younger and more naive than him was experiencing a sex scene before him.
However, little he knew that this scene was stimulating his own development. Unknown to him, his former hairless armpits were sprouting their first hairs which quickly turned into a decent bush of hair. His legs lengthened until they were as long as Bradley's as well as his arms and torso.
Those pathetic feet started to transform into the feet of a man, widening and elongating until they were size 13, a little smaller than Bradley but manlier in their look.
Although he was ashamed of the small nub that it's his penis, he can avoid feeling aroused by looking at the young couple's sex show. He was unconsciously masturbating while he watched and his dick was pumping bigger with each stroke. His balls were doing the same and finally hair started to sprout there too. He was so mesmerized by the scene that he didn't realize how much his stamina had increased since his last cum because precum was flooding his left hand but he was still too horny to finish.
As his penis was throbbing with excitement, all of his body was doing the same, muscles and hair were growing everywhere until he has nothing to envy to Bradley. His hands, big and calloused now could felt the rough skin in his chest and abdomen.
"Oh, I feel funny!" Bradley told Vivian before he shot his first ejaculation in her womb. To their surprise, a deep groan sounded at the same time and they quickly noticed at the sturdy man next to them.
"Holy shit!!" Ryan's voice boomed in a deep baritone as a result of a bigger and thicker neck. He didn't know it but his jaw had squared and a beard has grown there too. He arched his wide back before he left all of his new humanity to fall exhausted on the bed.
"Oh great!! You made it!!" Bradley told him really excited.
"I did.. what?" Ryan asked him without realizing what had just happened.
"Look at yourself." Vivian smirked while she pointed to a full length mirror next to the bed.
Ryan tried to stand up but his new weight made him lose balance and almost fall. However, Bradley reacted quickly and helped him to stay up by holding his broad back. They both made some steps until they were in front of the mirror.
When Ryan looked at his reflection and saw a hirsute and brawny young man instead of a wimpy boy, he first freaked out but then he saw the young man next to him smiling at him, and he smiled back. He was the bigger one again!
