longer.
"Now Kathryn, if you want to be my submissive you'll have to do much better than that. If you can't beg for my cock like a good little slut we should just give up now."
Kathryn chewed her lip, pressing her forehead against the back of the chair. She could feel the sweat dripping from her hair, and the cum dripping from her chest. Most of all she could feel the climax building within her. She knew one more thrust from her Master's cock would finish her.
"Master," she whispered hoarsely, struggling to speak clearly, "please fill my tight ass with your cock. I want you to use my body!"
She gasped as Master's rock hard tip pressed firmly against her. "Again."
"Master, please fill my tight ass! I want to be your dirty little slut!"
Once more she felt the tip stretch her ring. Once more it pulled away. "Again."
Kathryn felt tears of frustration prick at her eyes. She'd never felt so aroused; never felt so desperate to be filled.
"I beg you, Master! Fuck my ass with your beautiful cock! I want you to fill me with your come!"
This time she heard a satisfied moan behind her. Master gripped her by the waist, bracing himself against the chair before slowly, ever so slowly, pressing forward. His thick, firm head pushed slowly against Kathryn's wet, tight ring, stretching it wide as it slipped in.
"You will come silently for me, Kathryn. If you make a sound, I'll have to punish you."
She nodded, biting down on the rope around her wrist in an effort to hold in her moans. Her asshole stretched wide to accommodate her Master, wider than ever before, wider than she believed possible. An eternity passed as her ring fought against the pressure before finally, blissfully, Master's thick head spread her fully, opening her like a flower and allowing him to slide the length of his shaft deep inside her.
Almost immediately Kathryn began to come. She felt honey gush from her dripping, pulsating pussy as her ass was filled tight by Master's rod, and with each wave of pleasure she felt her asshole contract around his shaft, squeezing it over and over until, with a low, long moan Master sprayed his seed deep inside her.
Kathryn's teeth dug into the rope, painfully pinching the skin of her wrist, but she remained silent as ordered. Even as Master slowly withdrew his cock from her tender, twitching asshole she didn't make a sound. She simply lay on her knees, frozen in place by the tight ropes, overwhelmed by the sensations flowing through her body. The harsh, rough tightness of the ropes at her wrists and knees. The pinch of the leather belt at her ankles. The spurts of searing hot come jetting deep in her ass. The fading pulses of her orgasm, clenching her asshole around Master's shaft as he gently slid it from her.
This time her asshole didn't snap shut the moment it was no longer filled. As Master's spent cock slid from her, her ring remained wide for a moment, a pink, tender opening dripping thick, creamy come before her muscles puckered it tight once more.
She heard Master tuck himself back into his trousers and retrieve his discarded suit jacket from the floor before he returned to loosen her straps. He worked silently, methodically, removing first the belt from around her ankles, then the rope from around her knees, and finally the straps binding her wrists to the chair back. The moment her hands were freed Kathryn flexed her wrists, massaging the blood back into them.
"This was very pleasurable, Kathryn," he said, quietly. "Thank you for being brave enough to try something new. I hope you enjoyed yourself."
"Yes, Master, I did" replied Kathryn, bowing her head demurely.
"You can call me Patrick now, I think," he said. "Good night, Kathryn."
With that he was gone, leaving her alone, naked and confused. Did I do something wrong? She couldn't understand what had just happened. She'd done everything he'd asked. She'd followed his orders and allowed him to use her body as he pleased. What more could she have done?
