'Conditioning'.

"...yes Miss Locke..."

Shamefaced, you reluctantly return to your seat, hunched a little to (belatedly) hide your erection.

Meanwhile, Miss Locke returns to her desk and begins rummaging through it. Before you have time for your humiliation to fade into boredom, Miss Locke stands up and walks over to you, a faint smile on her face.

Your eyes are too drawn to the bounce of her cleavage to notice what she has in her hands, and by the time you realize you've been staring again, Miss Locke has reached you, stepping around behind you with a firm, "hold still."

Miss Locke pulls your arms back, and you feel something click around your wrists. You realize she's used a pair of handcuffs to cuff your wrists together, and giving a brief tug, you find that the chain connecting the cuffs is threaded through a piece of the chair, leaving you handcuffed to it.

"W-what the hell are you doing!?" Realizing you've just been bound to the chair, you blurt out an exclamation of surprise to Miss Locke, who has stepped back in front of you.

"Language." Her voice is more sultry than strict, but you suddenly feel a stinging pain on your cheek; she just slapped you!

"As for what I'm doing..." Miss Locke kneels down and undoes your pants, dropping them to the floor along with your underwear. You're still hard, so your cock springs free, making you flush with embarrassment.

"...I'm going to be conditioning you a little. You're really getting too distracted staring at my breasts, so I'm going to condition you to associate them with...unpleasant sensations."

She holds up her hand, and you realize she's holding a riding crop. Stepping close, she pushes her cleavage into your face, leaning forward so that your eyes are level with her ample bosom.

You feel your cock throbbing harder despite the situation, then cry out in pain a moment later as the riding crop comes down hard on your thigh, leaving a stinging red line on your skin.
