She resented the fact that he was forcibly interrupting her pleasure. But it did return her faculties to her, long enough to realize once again that this wasn’t really happening, and that she was in control of things. She hadn’t heard what Jason said, but this time decided quite consciously to continue.
She could show her anger now without Jason being able to do anything about it. Besides, she knew that he was struggling to hang on to his mind, while her pussy did its work on him, her breasts and body draining his willpower.
“Shut up. It’s too late. I’m screwing you and there’s nothing you can do to stop me.” The words, she figured, would send him over the edge and he’d stop resisting. Jason never thought he’d ever be in the situation of resisting a beautiful woman’s advances, unless she was married or had some disease or something. But neither was the case now.
Her words were a temptation of defial. He placed both hands on her hips, and started to push her away, hoping she’d forgive him, and even be thankful that he gave her a chance to think rationally about her actions. His cock started to slide out. The tip was swelling inside her, though, at Katie’s command. Jason felt his skin stretching. He didn’t know how big he was, and he wouldn’t feel much pain as long as the Device was working.
Katie’s orifice tightened around the base of his cock. It had grown inside her, and she was growing tighter. He pushed harder against her hips, but couldn’t slide out. He was locked inside her. He slid back in to try again, and this time the sensation of sliding into her warm flesh pushed him over the edge. Her words had come true. He lost his last reasons for stopping it, and his thoughts faded with only one intense purpose remaining. He started sliding in and out, making no further attempts to escape.
Katie giggled once. “That’s it, animal. Fuck me. Then, maybe I’ll let you go.”
It was all a game, Jason and Katie both knowing the rules quite well. Each word, each motion, could do nothing but stimulate desire. Jason’s attempt to “stop” her was played perfectly.
He probably knew it would excite her. And now, he was hers, undulating against her, and pulsating inside her. She giggled again once more, watching Jason turn into the animal she wanted, before her own thoughts turned again towards the act of mating. She grew hot inside as the excitement increased.
Katie was approaching her climax, but still had a handle on what was happening. Her words came one at a time, with each breath and each of Jason’s thrusts. “I ... want ... all of ... you ... inside ... deep ... yes...”
It took a few more seconds before Jason understood that Katie’s words were not just the usual ones that come to a female mind in the heat of passion. With every undulation, he felt as if he was sinking deeper into her, deep between her legs, feeling more and more of her. But it didn’t just seem that way ... it was true.
