((You decide :3))
"I'll let you decide dear sister..." He told her in a soft tone. "Maybe go back to dads lab or just have some fun here?" He asked he.
"Oh no. I've had enough of Dad's lab after what we've gotten ourselves into. Some fun here is just enough." she looked over and couldn't help the roaming eyes even though it was her own body she was looking at
"What kind if fun then?" He asked her while he watched her. He slowly moved over to her and then sat down on the edge beside of her. "You know something that could keep us entertained?" He asked he while he watched her.
"Well... Would you want to see it naked then?" He asked her with a giggle while he watched her. "I probably don't have anything you haven't seen before you know?" He asked her.
He slowly nodded at her words, before he then pulled off the top. "Want to see that last part? Well.. You'll get it as a reward once i think you deserve it!" He told her.
"What do you think dear sister?" He asked her with a slight smile. "Make me feel good!" He told her. "You know this body better than anyone you know?" He asked her as he slowly moved closer to her.
