Marina's heart was beating fast. The clock ticked over she knew that soon it was time for Sir M to arrive. She reflected on His last words to her in the session room. Tomorrow's session you are going to thank your Sir, for punishing you for such disobedience."

She wondered what He would have her do. She thought about what her Master would have her do and then realised with a pain in her heart.

The door opened and Sir M strode into the room. Girl kneeled instantly and lowered her eyes.

"Good girl" Was all he said.

Silently she felt Him attach a short leash to her collar. He gently tugged at it motioning her crawl and follow Him. The ground underneath her was cool, her hands and knees ached. She wondered how long He'd have her crawl.

He stopped before a door, and swiped it with a card, that He fished out of His pocket. A little green light lit up and the door opened. He tugged on her leash and girl proceeded cautiously behind Him.

The room was dark, and it took some time for girl's eyes to adjust. She saw various leather strapped benches and implements neatly arranged on shelves around them.

Sir sat on a bench and motioned to His cock. "I believe girl needs practice in servicing a man's cock."

He saw her cringe slightly and shook His head. "Is this the way a good submissive should act? Hmmmm?"

"No Sir.." She answered meekly.

"For such disobedience so early in this session, you have lost the privilage of training using My cock. Instead..let Me introduce you to a cock gag."

"Please Sir I am sorry...I..."

"Did Sir permit you to speak girl" His voice laced with anger.

He watched her lower her head, and whimper in frustration. "I said be silent."

He stood up and proceeded to walk to one of the shelves, He took His time selecting a good 7" rubber cock and a black leather head brace. The girl looked up curiously. "Open wide." He slid the cock through the brace and attached it to her head. Already it seemed that she was having difficulty managing the cock. He smirked.

Tugging at her collar He led her to a long leather lined bench. "Straddle it."

Girl climbed up and lay on her stomach along the bench. Her breasts hung over the other side and her ass stuck up in the air. Her cunt was on display as her legs were spread on either side, and she could feel the air against her exposed flesh. She felt Sir take her right wrist and buckle it down with one of the leather straps. He did the same with the other. She whimpered in confusion, but remained as still as she could. She could feel Him behind her as He grabbed her ankle and stretched her leg to the other strap. When both legs were tied in, she whimpered in her shame being so exposed, while on the other hand her body reponded to the humilation of it all.

She shivered as she felt a leather crop being traced over her back. "Girl needs to remember how to be a good girl and be a good cocksucker."

The crop trailed down to her exposed cunt, she knew her clit was protruding rudely on display. The leather crop end rubbed against her clit, she moaned through the cock gag.

THWACK! The crop suddenly descended sharply on her cunt. Her muffled screams choked, through the cock gag. The crop rubbing against her clit.

THWACK! Another sharp stroke, then the crop end once more rubbing her swollen clit.

girl lost count at how many times Sir struck her in this way, but she writhed in pleasure and pain, as her cunt became wetter and the sting grew sharper. her screams suppressed by the cock that was pressed deep in her throat.

"10" He said quietly and proceeded to rhythmically spank her ass with His hand. Left to right cheek, He spanked without pausing, watching her ass cheeks turn pink, then red. Her cunt flowed freely. He knew she needed it.

"I think we need to work on cum control, don't you girl?" He grinned, knowing she couldn't see Him.

He felt her moan in desperation and chuckled. Pulled out her butterfly and attached it to her clit.

"Shall we try again?" He said coyly as the butterfly was instantly placed on high speed......
