Janice stared intently at the two remaining box, uncertain. Finally, she pointed to the largest.
"Open it."
Biting her lip, she did as Clark said and read Master Series Claw Expanding Anal Dilator Butt Plug. When she saw the plug that would be inside of her for at least 7 hours, she gave a little hiccup. If she thought yesterday had been challenging, this would be even more so. Nonetheless, she felt a thrill of excitement rush through her body. At least she'd only be plugged for 7 hours rather than 9. On the other hand, this plug splayed out in 4 directions rather than 2. Her bottom had been tender yesterday, but not sore. She could only imagine how full this would be inside of her all day. She felt her nipples harden with anticipation.
"Perfect," Clark said. "I was hoping you'd pick this one. Now. Position."
Janice didn't hesitate. She bent over, cringing just a bit when Clark swiped her bottom with the cold lube. He pushed his fingers inside of her, scissoring his fingers. When he felt she was ready, he pressed in the plug.
"Please, Clark. It's so big! Please, go slow."
"Whose ass is this?"
"Yours," Janice answered, whimpering slightly.
"Who was being a brat?"
"I was."
"Do you trust me?"
"Absolutely."
"Then trust me now, babe. I'm not going to hurt you. I'm just reminding you that you belong to me."
He was right. All of last week she had behaved badly. She had backtalked him, once in front of a customer, complained when he wanted to fuck her, then complained because he didn't fuck her often enough. He had every right to train her to behave better and she knew it. Secretly, she had hoped he'd do just that - take her in hand, prove that he wasn't going to let her get by with going back on her promise to be a good and obedient submissive. Still, she'd never expected THIS! Yesterday had been humiliating but surprisingly erotic, being filled all day with the first two petaled plug, but then, she had to admit, when he had fucked her over his desk she'd had one of the most explosive orgasms of her life. Maybe he was right. She wanted to trust him, wanted him to be the stern disciplinarian she'd always fantasized about.
"How long will this be inside of you?"
"Until you take it out."
She herself had insisted on this rule a long time ago when they had first entered into a D/s relationship and Clark had readily agreed. Whatever he put in or on her stayed there until she used her safe word or he took it out. She'd never regretted this rule and wasn't about to start now.
Janice cried out, sure the massive plug would rip her in two. Clark, though, did go slowly, allowing her body plenty of time to adjust. She was humiliated and felt a delightful uncomfortableness, but no pain of any kind. Finally, the plug was seated inside of her. She could feel her sphincter close around the narrow base and the plug's four petals open.
"Clark. Please."
"No whining, Janice. None. No begging, either. You will open the store on time and go about your job as you always do. There had best not be one customer who comments about anything odd regarding you. You will smile, walk normally, sit without wincing. Understand."
Janice accepted Clark's hand and stood upright, the plug filling her body.
