Jeff thought about his brother’s proposal. He did kinda feel bad that while they were only 1 year apart, Jacob was unlucky enough to get the short end of the genetic stick in terms of manhood. He thought it was best to just give him some time to enjoy his new penis, it was only temporary. Plus Jeff did bring this swap on himself, best to follow through on his kinky little idea. He secretly thought the whole situation was hot as hell.
“Sure, but only for 24 more hours!”
Wow thanks bro! I’ll take good care of it!
“Yeah yeah go take a shower or something before I change my mind, you’re all covered in my cum.”
That night Jeff tried to get some sleep but kept hearing his brother moaning in the other room. He was really getting all the use he could out of his new dick.
Jeff decided to check the chronivac to see what changes he could make to make himself more impressive and was met with a notification.
“Deal made, all current changes will be unalterable for the next 24 hours, no new inputs allowed.”
Seems the chronivac honored promises.

The brothers went to school the next day.
“Hey dude you coming to the party tonight?!”
“What party?” Jeff asked his friend.
“The pool party at Matthew’s house, duh.”
“Shit, that’s tonight?”
Jeff would usually be down for a party, only problem is that it’s a pool party. Jeff played waterpolo so he was fine taking a speedo but with his brother’s pecker he might not want to do that.
“I guess I could always borrow Jacob’s swim trunks.” He thought to himself.
“Sure I’ll be there.”
The rest of the school day was pretty uneventful. Jeff did however spot his brother sitting with some of the older high school kids. It also looked like Jacob decided to wear some skinny jeans that left little to the imagination...
“What a show off.” He thought as tried to cover up his little boner.

“Hey Jacob I’m heading to a party can I borrow your swim trunks?”
“You mean Matthew’s party?”
“How do you know about that? Matthew’s a senior.”
“He invited me! And yeah you can totally borrow my trunks. I actually already borrowed your speedo, hope you don’t mind.”
“Calm down there bro, don’t forget it’s my 6 inches you got.”
“Yeah I know, just let me some fun with it for now. Oh and it’s actually 7 inches. I measured it last night.”
Jeff took the swim trunks to his room and got ready for the party. He quickly measured his brother’s dick out of curiosity and sure enough, 3 inches like he thought and 4 hard.
“He really didn’t give me much to work with did he?” Jeff sighed.

Jeff and Jacob arrived at the party. Jeff hated how the baggy the swim trunks fit, especially in the front. Luckily they still hid his lack of size really well and his swimmers physique kept him looking good.
Jacob was skinner than Jeff but that didn’t matter, all attention went straight to the speedo bulge.
“Hey guys glad you could make it!”
Matthew began speaking to Jeff when he noticed Jacob’s bulge.
“Woah, someone sure is packing! Looks even bigger than at school.”
Jeff just cleared his throat. “Ahem!”
“Oh right my bad, right this way guys.”
