She won't be able to sit for a while!

Without the slightest hesitation she went over to the desk and bent over it as He had ordered. "Spread your legs, slut," he demanded and pushed her legs further apart with his foot. "I am not pleased at all with your selfish behaviour, **** girl," he said, playing with his belt. "You really seem to need a little lesson to refresh your poor memory, don't you??" "Yes, Sir," she whispered, terrified at the thought of what was in store for her any second now.
At that very moment He raised His arm and His belt came down on her ass for the first time. While the sharp pain was still shooting through her she managed to count "One, Sir, thank You."
SMACK SMACK SMACK... He did not give her a rest but kept on hitting her ass with His belt without mercy while she was all the time obediently counting out aloud and thanking Him after each stroke. It didn't take long till she had tears streaming down her face. She really thought she couldn't stand another single blow. SMACK Ouch.. Her ass hurt so much now, she started sobbing... "I'm waiting, slut," she could hear Him say,"How many was that? Or do I have to start over?" "E-e-eighteen, S-Sir," she cried out. SMACK She started to scream in pain and was sobbing so hard now that she couldn't continue counting. He waited till she found the breath to thank Him, just as the next blow came down on her exposed ass.
Her ass was red as fire and stinged like hell. He really hadn't made it easy on her but hit her ass with full ****. It felt like she wouldn't be able to sit for a whole month.
After the twentieth blow He stopped, put the belt away and moved closer towards her, putiing His hands on her red stinging ass. Gently He stroked her ass cheeks. "What did you learn today, **** slut?" he asked. In between sobs she replied "Sir, i..i..i learned that i will never cum without Your permission, Sir. Thank You for teaching me."
"You're quite welcome, my little slut," he chuckled.
He turned her over and held her tightly, looking at her face. Her eyes were still teary, and her whole face looked swollen, streams of tears having run down her cheeks. It made Him smile. 'She is beautiful when she has cried,' he thought to himself. His lips touched hers and He kissed her gently.
Her legs finally gave in, and she collapsed in his arms. Smiling, he carried her to the bed and gently laid her down. "Get some rest, little one, the night has only just begun."
