Kathryn sat on a shelf in her home, in standby mode. Her gynoid body was undergoing repairs, and since she was nothing but a helpless little box, she had nothing better to do but sleep.
She awoke as she felt her power turn on. "It's me," she heard her boyfriend say, "I got something for you."
"Plug it in", she said, and soon felt something obligingly connect to her data port. Her autodetect protocols began identifying her new body.
"I'm... a sex toy?" She was used to having a synthetic pussy. She was not used to BEING a synthetic pussy.
"I thought you'd want something to pass the time. Do you like it?"
"There's nothing to 'like' if we're not doing anything, silly."
She soon felt his tongue trace along her labia until it reached the nub of her clit, which he gently nibbled. Foreplay was nice, but she wanted more.
"Let's skip to the part we're both waiting for."
Moments later, she felt lube being squirted into her, cool and slick. Soon that sensation was replaced by her boyfriend's erect cock entering her.
He started stroking. It wasn't just a part of her, her entire physical being was wrapped around him. What a feeling! Her cylindrical body expanded as he thrusted into her, and contracted as he pulled back. In, out, stretch, squeeze. She was catatonic from ecstasy, and lost all sense of time.
At some point he held her in place and started cumming. She could feel every pulse of his orgasm in her tight embrace, every hot squirt against her silicone interior.
He gently pulled out of her. She could feel the lube and cum dripping within her. He placed her gently down on the bed, then cleaned himself off. Then he turned to her. "Want me to unplug it and clean it out?"
"No. Leave it plugged in for now. Leave me beside the sink." He did so, and she felt a warm sense of contentment. This was the proper place for a used sex toy like her.
