Then, having his "victim" tied to his chest (Not too tightly, of course), he strikes a double biceps pose while bouncing his pecs against the chin of his victim. And then he wraps his arms around his victim's head, shoving his face deep into his pecs while flexing his biceps and bouncing his massive pecs. (I'm out of ideas now, sorry )
Sorry....I'm afraid your request for mercy is too late, bro. That chest expansion crushed his skull like a ripe melon....he was snuffed instantly! The muscle-brute then relaxes the huge muscles of his chest and the smashed head is pulled down to the ground by the dead weight of the body into a lifeless heap at his feat! Soy....should have spoke up sooner!
