Sal took a deep breath to ready himself for the flexing. In doing so his large chest grew even more massive. His lats bulged to barn-door width. Mightily he raised his heavy arms up into a double bicep pose. He lightly twisted his torso to view the flexing of his obliques in the closet mirrors before him.
"Oh Sal, you are so muscular and strong" in a mocked swooning tone
"And you're getting bigger all the time"
"Look how small I am to you" continued Jorge And it was a sight to behold. Jorge being completely blocked from view when he stood behind him. Sal's massive arm in pose was the size of Jorge's head.
Jorge got erect; not because Sal's physique was a turn on, but because he, the much smaller man was about to dominate his behemoth stepbrother with HIS muscle - the Penis Grande.
"Oh Sal do you think I can become as big and strong as you" said Jorge in mock admiration Jorge now took off his t-shirt to reveal a tanned, tatooed slim torso with a flat chest trailing down to a hairy flat tummy and stood next to Sal. Sal became uncomfortable, knowing what humiliation was to follow.
Jorge flexed his slim brown arms that had no tricep development whatsoever and only a small bicep development.
"Look at me Sal"
"OK big guy remove those fem tights and show me your endowment" Peeling down the spandex from the stallion-like , 30 in. thighs was not easy. But once down the sight was something to behold. Two tanned perfectly hemispherical buns completely hairless. Below the tanned butt were legs that stood like pillars of granite.
"How spectacular you look. Move back so my boys can't see their UncleMuscle naked from the swings"
"But what is this little appendage hanging between those monstorous legs?" Flicking it "Oh how cute". Big muscleman with a little no-muscle dick" "HA!"
"And where are those balls Muscle bitch?" "Big muscleman can't even produce sperm" "HA" Jorge was relentless with his ridicule. Sal accustomed to it since adolescent, shifted his stance, and just looked straight ahead in the mirror reflection.
"Now let me show you a MUSCLE" said Jorge cupping & jerking his crotch. Jorge dropped his baggy jeans revealing skinny hairy, brown legs with his huge cock tenting inside his boxer shorts.
"Flex those big biceps for me stepbro" Jorge & Sal both looked at the contrasting image they saw in the mirror.
"Behold the muscle that counts, in a swift slip Jorge dropped his boxers below his skinny legs. He kicked them away. Pointed to his near 9 incher standing erect.
"Look Sal, this is what I breed with. Look at those mango balls." Jorge was well endowed in both respects.
"HA, whose superior Sal?" bragged Jorge to Sal "Who can breed and who can't?" pointing to Sal's small endowment between his two monstorous thighs getting erect to its full 5 and half inches. The vision of Jorge's massive cock, and the humiliation excited him. Sal never knew why.
With a swift kick to the back of Sal's knees, Jorge had him reduced in statue. Sal buckled.
"To your knees Muscle Bitch. Pay homage to the MUSCLE!" Jorge twisted slightly to show off the glistening head of his erect monster cock, now swinging before Sal's handsome face below.
"Suck it Bitch !" Jorge stretch his slim brown body with cock erect Sal was salivating. He wanted that monster cock to gag him. Jorge palmed the back of Sal's head & began to move it in a swift pounding motion. "AHHHHH!"
