Karyn, the smart ass

Jon felt his backside tingle, it felt as if the seat of his pants had vanished so his ass is visible. "Karyn?" Jon asked. "Yes dear" she replied. Jon heard her voice coming from behind him. As she spoke he felt his butt cheeks move along with the words, the air coming out through his rear. "oh my god, you're... you're my rear end now?" Jon said. "ewww" Karyn said. "unwish it now, and.. and where is everything, why can't I see anything" "you can't just unwish things" Jon said. "but I can make them better for you." "I won't be happy until I can see, eat, and breathe, and I definately don't want to do your ass functions!" Karyn said annoyed. "Ok, Ok" Jon said. "I wish that I do not have to use the bathroom for as long as karyn is my rear end and she is able to see, eat, and breathe like this."
