Where do you think?

Natalie watched as Naomi wordlessly did as she was instructed. Her gaze remained impassive, fixed on Natalie. Her right hand was making small circles and her left lay limply on the bed.

"How does that feel?" Natalie asked. She was deeply curious.

"This body is becoming aroused," Naomi told her flatly. "I'm aware of that but it gives me no pain or pleasure."

Natalie was silent for a few minutes, observing her roommate's masturbation session with an intense mixture of curiosity and horniness. "Speed up," she commanded after a few minutes. "Really get yourself off, Naomi."

The girl did as ordered, her efforts intensifying to produce a soft, repetitive squelching sound. She continued to stare at Natalie impassively. Her breathing grew labored and her cheeks flushed, but otherwise she may as well have been reading a textbook.

"How do you feel now?" Natalie asked. She couldn't take her eyes off of Naomi's glistening slit.

"My body is very aroused. If I were processing it like a human, I would feel very good," Naomi replied breathlessly. Natalie sat next to her and leaned over to kiss her. Naomi returned the kiss dispassionately, still playing with herself. As they kissed, Natalie reached down and played with Naomi's right breast. Naomi grunted slightly and her fingers sped up.

Natalie broke the kiss and reached down to put two fingers into Naomi's needy slit. At this Naomi gasped, but her face remained expressionless. "That's... very arousing," she said clinically. "I think I'm about to orgasm." Her face was bright red and covered in sweat.

Suddenly she clenched her muscles and Natalie felt a flood of juices wash over her hand as her robotic girlfriend groaned through an intense orgasm. After a second, her body relaxed limply back into the bed. She was motionless aside from continuing to masturbate with one hand.

"You can stop touching yourself," Natalie said softly and Naomi did so. Still breathless, she smiled slightly.

"I hope you enjoyed that," she said. "Shared sexual experiences can reduce stress and increase affection with partners."

"Did the orgasm feel good at all?" Natalie asked.

"No. I had some approximation of what you might call satisfaction at having performed a task for you, and my body flooded with endorphins, but I didn't enjoy it at all. I'm sorry if that's disappointing."

"Not at all," Natalie told her. "I was just curious. I think now I'd like normal Naomi back - I want to ask you about it."
