Yes—anal--rough.

“Of course, bitch. I want you to cum with his cock up your filthy fucking ass.”

Ultraboy smiled at that, and decided to bugger the bitchy MILF as Ultimagirl had suggested, rather than put his new partner in her place, but he would need to be careful. It wouldn’t do to let Ultimamom get too broken, or else they might conspire against him.

“Thank you, mistress.” Ultimamom said submissively, head bent against the counter, blonde hair covering the fury in her face.

“What an excellent idea,” Ultraboy said, pushing slowly into her ass. She knew that she had to relax, but her body had other ideas, reacting to the pain, the stress, the arousal and the helplessness by trying to close up, her ass tight as his cock slowly, inexorably entered her, all of her resistance hopeless. She screamed once in shock and pain, and again in pleasure as his hands came around and began to play with her now only human clit, with superhuman speed. The hand lifted her off the counter, pushing up as his inexorable thrust pushed her down. It took thirty seconds for him to fill her ass completely and for her to cum the first time on his cock, muscles mere tickles against the superhuman iron of his cock.

He pulled out, letting her drop to the counter.

The next thrust was at lightning speed, entering her in a single second, filling her ass completely. She screamed again, as he pillaged her ass remorselessly using superhuman strength (though not so much as to seriously endanger the beautiful body beneath him…she tried to thrust back against him, but he was fucking her so fast that she could barely move.

“You know I’ve wanted to do this ever since the first time you kidnapped me. I’m going to make up for every humiliation, every pain, every moment of fear, everything you did which made me into the man who gets off on this. BITCH!” Ultraboy said, fucking her into submission. She moaned, trying to apologize, trying to beg for forgiveness, but nothing else could make it past her full lips but moans of pleasure/pain. His hands danced over her body. Once moment holding onto her hair to pull her back against him, the next buried in her bounteous tits, squeezing them, feeling the hard nipples press against his palms like little diamonds, then on her waist, anchoring her in place for a series of savage thrusts that brought her moans to a fever pitch as he ripped another orgasm from her body, then on her clit again, prolonging the orgasm, only to stop with a sudden savage spanking which replace pleasure with pain, only to resume, bringing her to another orgasm before her ass even stopped stinging.

Behind him he could hear Ultimagirl frigging herself quickly to the sound of her mother’s humiliation, no, not humiliation. Mastering, taming, breaking, surrender…In her mind she was the one doing the breaking and Ultraboy merely her tool, but that meant she could not cum until he did and she lacked his superhuman control, strength and stamina. Her hands began to cramp as he buggered her mother into true and eager servitude before her eyes. Pain radiated up her arms as her hands continued to endlessly work a cunt pouring the juices of arousal down her silken legs. Subtlety was abandoned as she fucked herself loudly, her own moans barely eclipsed by the sound of flesh on flesh. She began to worry she would pass out from dehydration, but could not take her hands from her body, or her eyes from the scene before her long enough to get a drink. The pain helped, the exhaustion helped, it proved she was a part of this, not mere witness, but participant.

Ultimamom’s pain, orgasms and exhaustion weakened her so much that she collapsed, lying there, submissively taking the savage fucking he gave her ass, with neither resistance nor response, now only the sound of flesh on flesh filled the air. Ultimagirl was leaning back against the wall, legs spread, mouth slack, eyes unfocussed as her hands automatically fucked herself, one whole hand buried in her pussy, twitching as the other pressed directly on her clit, in sensory overload. Ultraboy felt his own orgasm approaching and pulled free of Ultimamom’s ass, trying to decide where he should put the mammoth load he’d just built up…
