Your girlfriend blushes, as she takes off her clothes, after stripping off her bra and panties, she looks at you with tears in her eyes.
"Honey, I have a secret to tell you."
Your girlfriend opens her "stomach" only to find a little keyboard like features and wires inside her body.
"Babe, you're a- a..."
"Yes, I'm a robot. You don't know this, but, I am not the biological daughter of the couple of this house."
"But why?"
"I was built in a lab just sixteen years ago. Because the couple have failed to give birth to a child, so I was built so they could experience what it was like to have a daughter. I'm really sorry."
"Sorry? I don't care if you're a robot or not! I love you, babe."
Your girlfriend blushes at your compliment.
"Thank you, honey! I feel so happy now!"
You two stood silent, until your girlfriend spoke up.
"You know, babe, you see the little computer in my stomach?"
"Yeah, why?"
"Well, it has a little program to alter my appearance. If you want to, you can do it."
"Alter your appearance?"
"Yes, you can change my hair color, hair style, eye color, bust size, etc..."
You feel a little perverted, as your girlfriend notices the bulge in your pants.
"Go on, change me."
You places your hands on to her computer, and wonder what to do.
