Donna could see his orgasm loading itself and responded with intensified enthusiasm, jacking him off furiously with her tits, trying to exert as much pressure and tightness as possible, while running her tongue through the slit at the tip of his cock. As expected, Isaac’s orgasm was signaled with a loud grunt, paired with thick white streams of semen plastering Donna’s face and the roof of her mouth. She tried to catch as much of it as she could in her mouth, not only knowing that Isaac expected her swallow it all, but actually craving it. She sat back, wiping the semen off her face and then licking her fingers clean.
About to do the same to her breasts, Isaac again stopped her. “I want to see you lick it off.”
“Yes, Master,” she giggled.
Slowly, teasingly, she lapped Isaac’s seed off the slopes of her breasts, holding them up to get a better reach. She gluttonously licked up every drop of semen, washing it around in her mouth. Even once she had licked herself clean, she continued playing with her breasts. Pulling them all the way up, she managed to get both of her nipples in her mouth, sucking on them and pulling on them even harder with her teeth. Even after ejaculating twice, the sight of Donna sucking on her nipples brought him back to a full erection.
“You’ve proven yourself to be a good slave, but you still need to be completely broken in. Get on all fours in the middle of the floor and spread your legs.”
Donna obeyed, getting into position in the middle of the floor. Behind her, Isaac got down and spread her ass cheeks, staring at her anus and semen-caked pussy.
“Well, well, well, it looks like someone got some bleaching done.”
“Alice told me that you enjoyed playing with her ass.”
“If you got your asshole bleached, that must mean you’re a trashy slut, and sluts like you need to be punished. Don’t move.”
He pulled his belt out of his discarded pants and stood up. Donna had a feeling of what he was going to do and was scared, but she was too horny to disobey him. Holding the metal buckle, Isaac swung his belt and lightly whipped Donna across the ass. She yelped in pain, feeling the hard leather bruise her lily-white skin.
“You need to be properly broken in if you’re going to be my slave,” Isaac joked, once again swinging his belt and whipping her wide ass, careful not to actually hurt her. All bravado and roll-playing aside, he was not a true sadist.
Donna cried out from the harsh strike, knowing that a long red welt was already stretching across her rear end. The pain of the strike was also euphoric in a sense. Isaac had already dominated and subjugated her body as his personal possession, now he was just rubbing it in and humiliating her. Yes, he was humiliating her, and she loved it. She wanted more abuse, she wanted her young Master to brutalize her body further.
“I have to make sure I whip the slut right out of you before you can really be my slave. Are you a dirty slut?” he asked, whipping her a third time.
“Yes, I’m a dirty slut! Punish me, Master! Beat my slutty ass!”
Happy to oblige, Isaac whipped her again and again, leaving numerous welts across her ass cheeks and marking her as his property. Every time his belt struck her tender flesh, Donna cried out in pain and joy, feeling a miniature orgasm quake within her. She had never imagined that she would like pain so much. It was a truly mind-twisting discovery. Or perhaps was her horniness just so intense that she welcomed anything even remotely sexual?
Isaac soon stopped and got down behind her, licking every square inch of her bruised milf ass. Overcome with lust, he spread her ass wide and inserted his tongue into her anus, making her shudder from the unusual sensation. A few girls had licked her there in the past, but never a man, and she had never felt it so aggressively done. Isaac was sodomizing her with his tongue, forcing it in all the way while slapping her ass and pussy, further beating her. He had wanted to tongue-fuck her glorious ass for years, and he still couldn’t believe his fantasy was coming true.
Knowing he had one last load to blow, Isaac stopped and reared back. Spitting on her asshole, he prepped his cock for penetration.
“Isaac, wait! I’ve never had anything in there but a few fingers!” Donna exclaimed.
“You’re supposed to call me MASTER!” said Isaac, grabbing her hips and forcing herself inside her.
Donna cried out like a cat with its tail stepped on, feeling a pain that gave her childbirth flashbacks. She instinctively jerked forward and collapsed, her body trying to get away from Isaac’s cock. He was upon her without mercy, slamming his body down on top of hers and forcing his cock inside her. She legitimately thought he was going to tear her open, she had no idea her anus could enclose such a painfully large mass. The fact that Isaac was actively pinning her down so that he could have his way with her increased the physical pain.
“My ass! Master, you’re raping my ass!”
For a moment, Isaac was concerned that he had gone too far, but then he realized that her calling him “Master” meant that she was simply stating a fact, but by no means objecting to it.
“You’re my slave, remember? Your entire body is my personal property and I can do whatever I want to it, including rape your ass,” he growled in her ear, playing along as he buried himself in to the base.
“You’re raping my ass!” she cried again.
Keeping her pinned, Isaac began thrusting into her with all of his strength, struggling to maneuver with such friction and tightness. One thing was for sure, Donna had been an anal virgin up until that point.
“You love it don’t you?” he asked, managing to ease his strokes.
“Yes! I love it!” she cried with tears streaming down her face.
“Beg for it!”
“Master, please rape me in the ass! I love getting my ass raped by your cock!”
With that, Isaac raised himself with his arms as if doing push-ups and began doing slow but deep strokes, barreling into Donna so deeply that even her gag reflex seemed to feel it. Every time he entered her, Donna shed tears of both pleasure and pain, experiencing indescribable masochistic joy at the forced sodomy. Being pinned down, her face pressed against the cold concrete floor, her ass being impaled without any hint of mercy, it was driving her so wild that she couldn’t think straight by any means.
But the position that often worked well in bed was proving unsatisfactory for Isaac on the cold hard ground. He was having a hard time getting the angles for penetration right. Deciding he needed to adjust, he momentarily stopped and threaded his belt through the metal buckle, then looped it around Donna’s throat into a makeshift leash. He then sat up on his knees, pulling Donna with him and never removing his cock from her asshole.
As she struggled to hold herself up on all fours, he resumed his thrusts, now able to move with more speed and power. He kept a continuous pull on the leash, leaving Donna gasping for air and unable to release the slightest noise as he butt-fucked her with almost sadistic brutality. He even reached around with his free hand and squeezed one of her tits with painful strength, making Donna cry out in pain. While he strangled it in his grip, its twin continued to bounce and swing like a chandelier.
