Emily strained against the restraints that held her spread-eagle against the wall. Her ass throbbed with the pain of the previous stroke.
She heard the whoosh of the flogger before she felt it strike her bare skin. Moaning, she strained again. But the chains that bound her wrists and ankles didn't give.
Another stroke of the flogger, another flash of pain--Emily had lost track of how many lashes she had taken.
The concrete wall was unforgiving against her tits, which stood taut. Her cock was fully erect, betraying her sense of arousal. Precum dripped down her legs. But she knew there would be no relief. Not yet.
"Why are you here?," her Master asked, delivering another stroke of the flogger before Emily could answer.
"Because I didn't satisfy your friend, Sir," Emily moaned. "Because I wasn't a good service slut."
The next stroke was the hardest one. This was just the warmup, Emily knew; the real punishment was still coming.
"What do you need?," her Master asked.
"Punishment, Sir."
And Emily meant it.

Emily was bent over the sawhorse, her wrists and ankles bound to the floor and her neck firmly encased in a leather collar. She felt his hands first. Strong, rough, and clearly experienced, they gripped her ass firmly and pulled its cheeks apart. She was ready.
His cock was larger than her Master's, and she knew that was the point. If she was going to be the service slut her Master wanted, she needed to be looser.
He went balls deep straight away, but--"thank God," Emily thought--the thrusting started slowly. Releasing her ass, he reached forward and grasped her ample breasts.
Emily gasped as his fingers pinched her tits together. She could feel the tip of his cock massaging her prostate with each thrust of his hips. The mixture of pleasure and pain had her eyes rolling back into her head within moments. And she could feel her own cock twitching with excitement as precum spasmed out of it.
