R02-47 stood in the corner of your room, shut off. You stroked your aroused dick, it makes a wet and slick sound with each stroke you make... You very quietly pant, groaning.
R02-47 sensed it, cause you programmed for 47 to turn itself/himself on whenever it hears you make such noises.
“Are you aroused, Sir?"
The "sex bot" is a blue, glowing robot with a sensitive dick that can shapeshift to enhance sexual interest. It has only one personality setting: being aroused. When overstimulated, it can cum and speaks in a robotic voice.
