More anal pain

Sarah leaves you panting for breath while she prepares her next torment. You hear her rummage through some drawers before the returns. She yanks you head back by the hair and presents a buttplugg to you mouth.

"Suck it, and suck it good"

Eager to please, you suck it like its the worlds tastiest lolipop. After less than a minute Sarah is satisfied and pulls it out. She grabs your red buttcheeks and roughly pulls them apart, exposing your asshole. She pushes the buttplugg in all the way despite your protests. Then she pulls out a harness and straps it on you like underwear. The straps hold the plug in but leaves you limp cock hanging. She fixes that by stuffing your cock into a small chastity tube and locking it with a padlock. 

"Please Mistress Sarah, not a chastity tube"

SMACK!
She smacks your red ass hard and thus stiffles any more protests. 

You try not to groan as she pumps the buttplugg, making it grow until you think its gonna stretch your ass apart.

"Please, no more! I´ll break!"
"That´s none of my concern."

"Buuaaaaighaia!"
Sarah slips a ringgag between your teeth and buckles the strap tightly behind you head.

"No more talking for you."

As she turns around she adds.
"But a lot more screaming..."
