Tim was lying on his bed when he heard his big brother call him from the kitchen. He knew why his brother called him and a big smile formed.
He hurriedly went downstairs, and there he was, his bodybuilder big bro, wearing a tight white wifebeater that showed all his muscular features. As he was about to have dinner, a steak was sitting on the table in front of him.
“Come on, bro. I need my daily protein shot.” The muscular man said as he banged the dining table with his hands.
It started as a joke a few weeks before. Tim told his jock brother that cum contains a high amount of protein and is good for muscle building. His brother immediately trusted him as Tim was a nerd and the smart one in the family.
Now every day before dinner, he would ask Tim for his daily dose of ‘protein shot.’ He would jerk his little brother’s dick with his strong bodybuilder’s hand and collect the cum in a shot glass before enjoying it like an appetizer. Being gay, Tim didn’t complain. It’s pretty much his dream come true.
Tim had another idea this time, though.
“Hey, bro. You know that sometimes when I cum I would miss the shot glass and spill it all over the floor and table?” Tim asked as he rubbed his big bro’s bulging bicep. Being proud of his body, he didn’t mind, of course.
“Yeah. Such a waste.” The big bro said, licking his lips after.
“I know a way to make sure it won’t happen again. ”
“Well, what about instead of using the shot glass, you put my dick in your mouth when I’m about to cum so I can shoot directly into your mouth? That way, nothing is spilled.” Tim knew his big bro was an idiot who only cared about his physique. He would 100% agree to this.
“That’s an amazing idea, bro! Fuck yeah! You are a genius!” He said as he flexed his biceps. “What about pre-cum? Does it have high protein too, bro? ”
“I think so” This is definitely not true, but what the hell, Tim thought.
“You leak pre-cum a lot bro, so what if I jerk you off with my mouth instead? That way, We don’t waste the pre-cum as well.”
Tim was taken aback at what his big bro said. It was even better than he planned.
“O-of course! That is an excellent idea!”
Tim’s big bro immediately kneeled in from of him and slid down Tim’s shorts. Tim’s rock-hard cock twitched as he felt his big bro’s breath on his dick. Pre-cum was already flowing from his cock.
“Shit, bro, you’re already leaking.” Tim’s big bro said as he licked the dripping pre-cum, from the shaft all the way to the cock head. Tim shuddered uncontrollably as he felt his bodybuilder brother’s tongue on his cock.
Then, he slid Tim’s cock in his mouth. A loud moan escaped as he felt the warmth and softness surrounding his cock.
“Ahhhh… You’re doing so good, brother. It feels amazing!” It was actually the first time Tim got his cock sucked. Nobody really wanted a skinny nerd like him. But there he was, getting his dick sucked by non-other than his 250lbs straight bodybuilder brother. “Make me feel good, bro! The better you make me feel, the more cum I shoot!”
Hearing that made the bodybuilder go crazy. His tongue was twirling all over Tim’s cock. He knew he was doing a good job when Tim’s moan grew louder.
“Aaahhh… F-flex your biceps bro! S-show me the progress you’ve made!” Tim asked, and his bro happily obliged, flexing his massive bicep for him to see.
Seeing his brother doing a double bicep pose as he sucked the life out of him made Tim go nuts. He grabbed his big brother’s hair like a cheap whore and pumped his cock deeper into his bro’s mouth.
“Here you go, bro! Your protein shot!” Tim said as he pumped his cock faster. “FUCK!!! HERE… IT… COMES!!!!!!!”
Tim’s entire body was trembling as he shot his nerd juice into the bodybuilder’s mouth. It was the biggest orgasm he’s ever had. Tim’s cock was pulsing non-stop as he shot more and more of his warm thick protein juice.
After he was done, his big bro pulled away. He could feel a drop of his cum dripping from the side of his big bro’s mouth, but he quickly brushed it with his thumb before sucking it up.
“Wow, bro! That was a lot of protein! This way definitely better!”
Tim said nothing and collapsed into the dining chair beside him.
He can’t wait for tomorrow night already.
