Katie put both arms around Jason, which was now very easy for her. Jason put his head on her shoulder.
“It’s my fault,” she said. “This is really spectacular. I know what it feels like. You’re ready. You’re just not as excited as I am. What did you do to excite a female when you wanted to...?”
“I was gradual. I’d touch innocent places at first ... Kiss, touch her nipples, rub where she liked it, put my fingers between her legs...” Jason realized that he was now telling Katie what to do with him. The words, and the images, started to work on him.
Katie took him to bed, and kissed him. He didn’t resist. She played with him, gradually stimulating him, like he had done to her before. She put her hand under his blouse, and touched his bra. He still didn’t resist. Jason’s pussy was getting wet.
The Device was even able to produce his scent’s effect on Katie. It caught her attention, and made her anticipate the copulation she wanted. The bulge in her pants had grown, and she removed her jeans and shirt. Then she put her hands in Jason’s pants, and quickly found the opening of his pussy. She stroked him for a while before sliding a finger inside. It was very wet.
“Wow...” was all that Jason could say. Katie stopped long enough for them to undress. She now inserted her finger all the way, feeling the softness around it, and watching Jason fade away into ecstasy. Finally she couldn’t stand it. She climbed on top of him, but couldn’t manage to find the opening with her cock alone.
In the ultimate act of consent, Jason reached between his legs and guided the tip of her cock into his pussy. Her cock was dry, and it didn’t go in at first. Jason’s touch on her cock was driving her crazy. She started moving, in and out, and with each thrust was moistened a bit, and slid further in.
They both chimed together; “Oooh” as she penetrated him, her cock finally vanishing into his body. Copulation lasted for several exhausting minutes ... Jason keenly aware of Katie’s presence inside him, and Katie feeling the semen building inside her, ready for the climax. They came a moment later, Jason feeling his cunt tightening involuntarily around Katie’s member ... and Katie feeling the hot come traveling through her body, through her cock, and finally relieved as it quietly spurted out from her cock and vanished into Jason’s body.
She collapsed, cock still inside, and a few moments later found the energy to move. Her cock, which was smaller now, slid lazily out of Jason. Neither of them talked for about 10 or 15 minutes, it seemed.
Katie was the first to speak.
“I’m never going to forget this. Now I know just how it feels. I can be a perfect lover, now that I know what does what! But you know something? We COULD have forgotten something.”
“What?”
“I know we didn’t need it here, but I bet you didn’t even think of it. Protection. Birth Control. For all you know, I could have just made you pregnant! To think! I could have made YOU pregnant!”
