The muffled screaming pleased him to no end, the masochist that he was, and he smiled and laughed at her misery.  "Fuck yeah!  Scream for me, bitch!  I'm the only one who's gonna hear it, and I fucking love it!"  His cock practically grew bigger from the intense sounds of muffled screaming.  "OOhh yeaahh!!"  He never once stopped to consider her as he slammed into her again and against, ramming her tight ass for all it was worth.  Though his saliva helped with the initial penetration, he had to keep thrusting to keep her lubed up further inside, his thick cock and hard flesh rubbing against her anal walls harshly.
