Massive Shawn

As I mindlessly slake a primal lust while feverishly jerking off over a hulking beast like this guy, I imagine him monosyllabically declaring, “GRRR, see Mongo grow more BIG!,” a la some movie monster, as he flexes and doubles in size, making the spectacle even more thrilling. I can’t explain why unlimited muscle growth is so erotic, but it's become an AI subculture now. If this guy showed up today, would he be dismissed as AI? Just look at the size of his arms and back here and cum.

Jeeeeees, that back, those shoulders and arms. Incredible. As Schroed says, his muscles have muscles!

Imagine that back pushing you against the wall; can't move, can't breathe

His back is unbelievable it's huge love to fill what's it's like

Do these guys know how hot they make other guys??

Absolutely unreal. His muscles have muscles!

Totally amazing!
