"What is it little bro. See something you like?"

That bastart. I don't know how but my little brother manage to switch our bodies.
I woke up this morning in his room daze and confuse. Feeling lighter and smaller than normal. It was only when I went to the bathroom that I realized something was wrong. The reflection in the mirror was not my tall and muscular body but the puny body of my younger brother. He just turn 18 but looked much younger. He was skinny and he couldn't build any muscle to save his life. Short and hairless, he really got the short stick of life. Me in comparison, was a 24 year old college graduate living his prime. I work out most days of the week and have been blessed with good genes, hairy, tall and hung. Because of it, I was shocked to see a hairless teenage body in nothing but some underwear in my reflection.
I quickly ran to my old room to find my own body and maybe some answers. Only see my body almost completely naked in my bed without me being in control. I was there lazily laying in my bed with my semi-hard cock out.

"Good morning little bro! Good to see you finally wake up"

He said in my deep voice while flexing my muscles.
"W-what? H-how? I d-don't understand.."
He just laughs,
"Well it's pretty simple. I switch our bodies. Now I'm the older brother!"

Says and starts taunting me with my old body. Out of nowhere he begins exploring my body and masturbating right in front of me! My cock starting to react and reach it's full size without me in control of it.

"What is it little bro. See something you like?" He says with a smirk in my old face. Touching every part of my body with my strong hands. God, I had such a nice body. A muscle body with an attractive face, an 8 pack with a hairy chest and armpits, a full beard and to top it up a nice 8 inch cock with a big pair of balls. And now he is touching everything like it belonged to him!

"Hggg, little bro, your cock feels really nice. How can you stop yourself from jerking off all day! I can't wait to use this monster on someone!"
He was stroking my cock lazily with one hand while he was feeling my hairy chest with the other one. Relishing every moment of it.

"S-stop it! That's my body! Switch us back!"

"Can't do little bro, this feel even better that in my old puny body. I'm not giving up this body anytime soon. So you better get use to it. T-this feels amazing! A-Ah f-fuck I-I'm cumming! A-Ahg!"
I see how my old body trembles from the intensity of my orgasm and cum all over my priced muscle chest. Panting and cover in cum he stand up in front of me smirking in his new face and says.
"Now get out of my room! I need some alone time with my new big brother body, specially with my new big cock. Hope you don't mind!"

Just like that he kicked me out of my old room to start masturbating again. I stood there in the hallway silent with only the audible sounds being the loud moaning and panting of my little brother pleasuring himself with his new body. Realizing I just watched my brother jerk off in my old body and steal my life completely. And there was nothing I could do about it.
Fuck.
