“W-what are you doing!”

“I’m jerking off, duh. Can’t you see I’m a bit busy here?”
“Do that somewhere else then, not in my room! I don’t want to see my own body masturbating in front of me!”
“ Dude, first of all, it’s our room, we share it. Secondly, you were supposed to be home later it’s not my fault you interrupted my me time. And finally, your body? Dude, we swapped bodies a year ago! It’s not longer your body, accept it. It’s my body and mine to enjoy!
"If I had my body back I wouldn’t be such a horny bastard all day. The only thing you do with my body is masturbate and have sex!”
“And what about it! It’s my body and I’m only satisfying it! I still remember when we first swapped. You body was so sexually frustrated I had to jerk off all day to get all the pent up energy out! You barely masturbated and your body needed it!
"M-my body was not that frustrated!”
Tch, yeah right. Admitted this body has a high sex drive and it wants to get pleasure all the time. I mean I literally had to train your dick to not get crazy for the first ass it sees!“
”…“
"You know I’m right. Now get out, and let me stroke my 8 inch cock in peace!”
“… Whatever…”
God, I thought he never leave. My little brother still think that this body belongs to him. It doesn’t any more. It belongs to me now. I’m the big brother with the big brother body. With the big brother muscles and the 8 inch, thick, and veiny big brother cock! And I do whatever I want with it! Like finishing masturbating. Mmhhh. Y-Yeah. Already a year, and it’s still as sensitive as I first touch it! It’s good being the big brother.
