Beg for it

If he hadn't said 'fuck' and 'ass' then from the tone of his voice you'd have expected it to come from a teacher trying to motivate a child. An almost 'sing-song' quality to it which made you feel almost obliged to beg him to 'fuck your ass harder'. But even without that you wanted him to fuck your ass harder, to make it hurt like it hurt before because that is the will of God. You consider what to say but aren't really good at such language so go for

"Please fuck my ass harder!"

The thrusts increase a touch in tempo and you congratulate yourself just as the man says "Carry on."

You pause for thought and then "I want you to hammer your manhood in to me."

"Say cock." he replies

"Cock?"

"Yeah, say you want me to hammer my cock into your butt."

"I want you to hammer your cock into my butt?"

Each word you mutter seems to spur him on more, the thrusts getting faster but the agony the Lord commands you receive is lacking.

"Say you want me to hammer my big black dick into your tight little white bubble butt!" He shouts, not with malice but certainly with desire.

"I want you to hammer your big black dick into my tight white little bubble butt?"

"Say it like you mean it."

Unsure of what he means you just shout as loud as you can "I want you to hammer my tight white little bubble butt with your big black dick!"

The grunts and cries, the wild, fast hard ass fucking you begged for comes to a stop without ever making you hurt like before. He pulls out of you and in an apologetic tone says "Damn girl, your ass just sucked the cum right out of me. You sure do have the skills to pay the bills. Hope to see you again real soon."

With that he seems to leave; leaving you with your used asshole pressed up against a hole in a wall after pleading at the top of your voice for hard anal sex.
