“Dude, are you getting hard from seeing my penis?” Asked Tom.
“Sorry, I’m still getting used to this thing,” said Andrew, forgetting himself.
“How can you be ‘getting used to’ an organ you’ve had for 20 years,” asked the little brother curiously.
“Shit, I wasn’t supposed to tell you. Well, the thing is, I’m not Anthony. I’m Andrew. Well you know me as Andrea. See, your brother and I were working on a body part exchanging device and a lab explosion at our house caused us to switch our entire bodies. Anthony is back at home in my body fixing the machine,” explained Andrew.
“That still doesn’t explain why you’re now going as Andrew instead of Andrea,” pointed out Tom. He had bought Andrew’s story though.
“You see, being in your brother’s body here made me realize that I’m a man. I don’t want to go back to my original body at this point but I’m not gonna leave your brother trapped in it,” said Andrew dutifully.
“Oh, my bad man. Well this explains a lot about this trip. Mostly why I keep getting romantic looks from my brother haha. Wait are you two still together?” Asked Tom.
“No. When I realized that I’m a man Anthony didn’t want to be with me anymore. And that’s understandable, he’s straight and he doesn’t want to be with other men,” said Andrew.
“Wow. So I’m on a fishing trip with my brother’s ex-boyfriend who’s in his body. That’s a sentence I wouldn’t have ever thought I’d heard myself say. My big brother’s little penis is so cute, look at it being hard but still being smaller than my own,” said Tom adoringly.
“Yeah,” Andrew blushed, “this thing has a mind of its own.”
“Let me show you how to pee while you have a boner,” said Tom, getting behind Andrew. He was eager to feel up Anthony’s body since his older brother would never have let him were he in the driver’s seat of his body. Andrew didn’t mind.
Tom wrapped his hands around Andrew’s waist and grabbed his brother’s hard cock with two hands, saying, “It’s gonna feel a bit unnatural but basically you have to push with your bladder until pee starts coming out even though you’re hard.”
Andrew felt amazing with Tom cupping his back and holding his hard on. After a bit, Andrew started to pee despite his hard on. He could feel that Tom had a monster erection pressed against his butt.
“Great job Andrew. Not many guys can pee while another is holding their junk,” said Tom, whose erection looked comically big in his sweatpants.
“Well I had a great teacher,” said Andrew, going in for a kiss.
Tom started making out with Andrew, taking a break to say, “Man, Anthony is gonna kill me when he finds out.”
“I won’t tell if you won’t,” promised Andrew sexily.
The two men explored each other’s bodies shamelessly. Tom did so with even more gusto than Andrew. It was kinky for him that he had access to his older brother’s skinny but sexy body. The sucked each other’s cocks for a while and then it was time to fuck.
They had vassoline with them which would have to function as lube. Andrew got on his back and lubed up his asshole. He almost tried to lube up where his vagina used to be out of habit but was met with a boner and laughed.
Tom happily fucked his brother’s body with Andrew in it until they both shot their shot. With a little more making out, Tom’s dick came out of Andrew’s hole. They cleaned up and headed home, agreeing that this was more of a hook up than a new relationship.
