Over the Line by Sierra Cartwright

place.”
    Her muscles were tight as she complied.
    He used his tongue to make her wet and to lap up her juices. He adored her taste. She made soft mewling sounds, and her body stiffened. He immediately stopped what he was doing.
    “Argh!”
    “Nice try. But your body gave you away. You’ll not be sneaking in any orgasms, I’m afraid.” He let her go and smacked her right ass cheek. “Kneel up properly.” When she did, he moved out from beneath her.
    He rose to stand in front of her. She tilted her head back to look at him. Her lips were parted and her eyes were wide. The earlier hostility was gone. Her hands were still linked behind her back as he’d requested. Despite her apparent frustration, she seemed softer somehow. “In answer to your question, no. It appears your orgasm will not be happening this century.”
    “Master Michael, you are a beast.”
    “Indeed,” he agreed. “I’m open to you convincing me otherwise.”
    “How, Sir?”
    “That’s a good start.” He reached down to grasp her nipples again. Since he believed in keeping his promises, he said, “Stand.”
    He pulled on the tips, lengthening her nipples and stretching her breasts.
    She grabbed his arms for support and hissed through clenched teeth. He continued until she was standing. “Let go of me,” he instructed. “Surrender.”
    Eyes wide with total trust, she did.
    He kept up the pressure until she was on her toes. “Beautiful,” he told her. “How does it feel?”
    “Oh, damn, Sir… It hurts.”
    “Was it too much?”
    “Yes. And not enough.”
    He understood, and he delighted in her. Abruptly he released her, only to gather her in his arms and pull her close. She snuggled against him, her chest heaving. He smoothed her hair then cradled her head. He placed his other hand on her back. “You’re a brave little sub.” After she pulled back, he said, “You’ve almost earned that orgasm.”
    She looked up. “Sir?”
    “My bedroom is upstairs. I’d like you to crawl up the stairs.” He knew what he was asking from her. She liked the intensity of a spanking and, he’d bet, a beating. She wanted to lose herself, let go, push the outer edges of a pain-induced adrenaline rush. But this… He was asking her to do something because it turned him on. “Your choice,” he reminded her. “But I want to watch your ass move.”
    “I’m beginning to think that’s one of your kinks.”
    “It wasn’t. Until I saw you walk across the patio at the Den. Now all I can think of is your ass. And I’m wondering if it’s red enough.”
    “I created a monster, Sir.”
    “You did. So is it? Your ass? Is it red enough?”
    “Why do you ask? Didn’t you spank it, Sir?”
    No doubt she’d earned her reputation at the Den. “Up the stairs. If it’s easier, I can fetch a leash.”
    Her wide-eyed innocent look vanished as she blinked several times in rapid succession. “I can manage on my own, Sir.”
    She pulled away from him, and he reluctantly let her go.
    With athletic grace, she lowered herself to all fours.
    “Wait a moment,” he said. “We’ll go upstairs soon.”
    She remained in position but looked at him with a frown.
    He crossed to a kitchen drawer filled with all sorts of random items and dug through it until he found two small clips. They weren’t as serviceable as proper nipple clamps, but since his toys were upstairs, these would work for now. He tested their grip on his pinkie to be sure she wouldn’t find them unbearable. Satisfied, he returned to her.
    Her breasts hung freely, and he’d never seen anything more enticing. “Since your nipples are already sore, these will intensify the sensation.” He bent to fondle her left breast, smacking it back and forth until she gasped. Then he brutally squeezed it. “I haven’t even touched your nipple and already it’s getting harder.”
    “Yes, Sir.”
    “Do you want me to clamp it?”
    She turned her head to look at him. “Do it. Please.”
    “My
