He grabbed her buttcheeks, holding them apart, taking in this cunt he was about to fill again for a second time. This time, he didn't need to check if she was ready. He moved his right hand around to her clit, swiping it with his fingers, and held his cock to her entrance with his left hand, pushing in to the hilt with one thrust. She cried out, finally experiencing the reason for the breeding bench: he was so deep inside her, and all she could do was take it.
As Master got into a rhythm, pushing his cock deep inside her again and again, grinding against her, he grabbed one of her dangling tits, pinching the nipples between his fingers as he thrust inside her, pulling on it lightly as leverage for the movements of his body.
His other hand creeped back around to her clit, gliding his fingers around, enjoying her failed attempts to gain leverage. Yes, his instincts had served him well with this slave. She was delightfully needy.
Each thrust garnered him a muffled "Ungh!" as she grappled with the intensity of her position. One of his hands moved to circle the star of her anus, so prominently displayed in this position. Still wet from its journey around her clit, his fingers rubbed gently against the opening, providing just a hint of pressure. As he suspected they might, her cries increased. He wondered if maybe they might revisit this breeding bench for a different purpose in the future. But during this window, his cum had only one destination.
Laney looked out, the mirrors reflecting her predicament back to her. Her body, covered in sweat again, dangled and strained against the cuffs holding her down, her back arched in place, her mouth open with wordless sounds coming out of it, her ass sticking up in the air. Her breath caught as Master hit a particularly deep spot, her desire reaching a peak.
Master sensed her arousal growing and moved his fingers back to her clit, shouting at her, "Come for me, my hungry breeding bitch. Show me how much you want my seed. Earn it!"
Laney screamed again as her orgasm tore through her, her desire to please her Master meeting a feeling of helplessness that turned her on more than she had realized it would. Her body tried and failed to buck against the bench, Master's cock inside her and the cuffs preventing the movement it craved.
Feeling her cum surrounding his cock, Master increased his own speed, no longer caring for anything other than filling his slave with his cum. He filled her with deep, intense strokes, almost leaving her body and plunging back in, until finally he grabbed her breasts and held his cock as deep insider her as he could get, his body twitching as he groaned, whispering to her "God you're such a hot little slave, and you're going to be even hotter with your belly swollen with my baby."
Laney shivered in delight. Her first breeding had been everything she had dreamed of. Her body was sore, and she could already tell that when she was released from the breeding bench and brought back to her room, she would need to stretch, but oh was she satiated. And today was just the first day.
She smiled as she felt Master's cock leave her pussy, the angle of the bench ensuring all his seed stayed safe inside her until she completed the waiting period.
She couldn't wait to repeat it all again the next day.
