The thrusting slowed down, but Kira's mind continued to race.
She couldn't speak. She couldn't see. She couldn't move. Darren had taken care of all that. But she could still think. That hadn't been taken away from her.
Not yet, anyways.
Another thrust and, this time, Kira couldn't hold it in any longer. Moaning, she pushed against the ropes that held her in place. Her cock was as hard as his, but she knew she would get no relief.
Not this time.
She felt Darren's hand close around her throat. Breathing was a privilege, of course, and she had lost it. Kira struggled harder, but the bulging cock inside her ass just grew larger.
Another thrust, another moan, another attempted breath.
The ropes dug into her wrists and ankles. Darren had tied them too tight -- he probably meant to.
Darren removed his hand from her throat and wrapped it around her cock. He was teasing her. And it worked. She could feel the pre-cum leaking out; it was the only lube she would get for this hand job.
Darren stroked her cock in time with his thrusting. She could feel the tension building. Soon...if he would just keep going.
A slap across her face and twisted nipples signalled the hand job's sudden end. Kira moaned again, this time in pain. Her breasts, already tender from estrogen, seared from the twisting motion of Darren's finger.
She felt Darren's weight shift as he pressed himself against her ample body.
"Ass or mouth?," he whispered into her ear.
She couldn't answer. The choice was entirely up to him.
"Mouth, I think," came Darren's breathy reply.
She felt his cock fall out of her ass and his hands fiddle with the straps on her ball gag. As soon as the gag fell from her mouth, his cock slid in to take its place.
She could feel her throat tightening around his cock head. She gagged; Darren didn't pull back. Her lips closed around the shaft, carefully hiding her teeth, as Darren began to thrust.
Quickly, she felt his cock spasm as her mouth filled with cream. Darren kept going. Kira swallowed.
Her job was done, and she relaxed into her restraints.

They'd met online.
Kira's personals post had been simple and direct: "Dom Me."
She'd provided the usual details in the body of her listing, of course.
23 years old. White. 210lbs. 6" cock. 44B breasts. Experienced. Open to anything kinky.
She'd received a barrage of replies, most of them useless. The men who inhabited sites like that had plenty of fantasies, but typically little ability to make them come true. They wanted a fuck-toy. She was ready to be one. But only if her Dom knew what he was doing.
