When he saw that the leash would not allow her to crane her neck forward enough to attack the member in question, he removed her muzzle.  "I want to have the stamina to fuck you into submission"  He muttered as he pumped faster, his member sliding through her cleavage, getting tighter around him as his member thickens, moaning softly.  "So I will make sure the next time I cum won't be for a long time...by marking you as mine now."  His eyes were dark and full of vengence.  Cuts and scraped littered his body, many or which she gave to him.  "Soon, after you're broken in, you will beg for me to cum, it will mean you have served well and will be treated in the best fashion."  She could feel his member pulsing for release.  "But for now you get what I give you."  He groaned loudly as his member erupted at the top of his thrust, thick ropes of cum hitting her face and screaming mouth.
