One day in class, Billy raises his hand and says, “Teacher, I’ll bet you £50 I can guess what colour your underwear is.”
She replies, “Okay, meet me after class and we’ll settle it.”
But before class ends, she goes to the bathroom and removes her panties. After class is over and the students clear out, Billy makes his guess. “Blue.”
“Nope. You got it wrong,” she says as she lifts her skirt to reveal she isn’t wearing any underwear.
“Well come with me out to my Dad’s car, he’s waiting for me, and I’ll get you the money.”
She follows him out. When they get to the car she informs his dad that he got the bet wrong and that she showed Billy that she wasn’t wearing any underwear.
His dad exclaims, “That mother fucker! He bet me £200 this morning that he’d see your pussy before the end of the day!”
