Metamorphosis

"Huh?! How is that possible, Daddy?...How are you seeing what's inside of me, when your finger is lodged in and blocks you from seeing anything inside?!" She was frightened at the thought of her son seeing her fleshy insides, which for some reason seemed more embarassing than lying naked in front of him without a fabric of cloth on her.

"When I say that I can see your insides, I only mean that I can see the part that's surrounding my finger, when I pull my finger out." He explained that he could only see the part that was exposed when her anus was pulled out a little bit, along with his finger, due to the intense suction force.
