Another Little Johnny Jokes

[NSFW]
Little Johnny walked into the bathroom and saw his mother drying off her vagina with a towel. Little Johnny goes: Mother what is that? His mother goes: Its a beaver. Little Johnny nods and walks out. The next day little Johnny walks back into the bathroom and sees his grandmother drying off her vagina. Little Johnny says: Grandma what is that? His grandmother says: Its a beaver. Little Johnny replies: Well it looks like a dead beaver because its tongue is sticking out.
