Miss Heath?

The curtain raises, revealing the gorgeous Miss Heath - but she's pulling on her coat, clearly getting ready to go. She looks at you and smiles wickedly.

"Mmm, back for more? Such an eager boy... I'm afraid I've been called away though. Don't worry, one of my best students is stepping in for me!"

She steps aside, and sitting on the stool behind her is Irma Scrottworth, a girl you vaguely know from one of Miss Heaths classes. She's a short, scrawny nerdy little thing, with thick glasses, greasy looking dark blonde hair that she wears in pig tails, and a generous smattering of acne. She has a boyish build, about as far from Miss Heaths curves as you could imagine, no boobs or butt at all. She's dressed in the school uniform, even wearing the straw boater hat which almost no-one else in the school bothers with, and is busily and unskillfully applying bright red lipstick to her mouth while staring with brow-furrowing concentration into a hand mirror.

Miss Heath gives you a peck on the cheek, pressing her warm, firm curves against you, as she prepares to leave.

"Have fun!" she whispers into your ear, before walking away with a wicked giggle. You watch her go, dazed and confused.

"Right then!" announces Irma in her silly squeaky voice, setting down her mirror, "Leth get down to buthineth!"

Oh, yeah, she lisps too. You'd forgotten about the lisp. You stare at the little nerd sadly as she snatches up the bundle of notes you'd slammed down on the counter.

"Goth, a hundred and twenty poundth! Thith ith going to be fun!"

She grins at you, displaying braces between her clownishly painted lips, eyes sparkling eagerly.

"Get ready, I'm going to kith your brainth out!"

You're painfully aware how much money you've so impulsively paid. You could try to ask for your money back, saying you've changed your mind, but the erection Miss Heath gave you is still throbbing in your pants - maybe you could even hurry after Miss Heath? But that would be pretty rude...

Irma stands up and grabs you by the tie, pulling your face down to hers. If you want to protest, you'd better do it quickly.
