Waltr'ass and the boner

After Frass'k left, the boy was left alone with Waltr'ass. "Umm, so... Waltr'ass... How does your possession work?"
"Well, we can just jump from body to body at will. It's as natural as breathing for you." Walter now eyed the boy with a smirk on his face. "Well, maybe not as this body has made you breathless..." he said while he oggled up the boys dick.
"So tell me, how big is it?"
"What... What are you talking about, Ivy? Oh wait..."
"It's ok, I can be 'Ivy' if you like..." Waltr'ass licked her lips. Meanwhile, Walter was thinking "I wonder how he would react if he knew how I really looked like?"
