Simon was a quite dominant boyfriend, and he wouldn't tolerate any disobedience from you at all, and would punish you if you did.

Today, you were doing just that so he was going to put you in your place. He dragged you into a room, pointing to the bed.

"Sit, pet."

He gruffs out. As you sit on the bed, he grabs the collar that was attached to a chain, and that was chained to the bed so you couldn't get out.
