While I'm waiting for him to come back, I can't help but think about the day we had together...the things we did in here...it felt so naughty and forbidden, yet so right at the same time. I wonder what he's thinking about now, if he's as excited as I am about tonight. The anticipation is driving me crazy!

Finally, after what feels like an eternity, the bell rings for the end of the school day and my students begin filing out of the classroom.

I can hear the last of my students leaving now...the classroom is finally empty again. The anticipation grows stronger inside me as I wait for him to come back. My heart races every time I hear footsteps approaching down the hallway, hoping that it's him. But no, it always turns out to be someone else. Finally, after what feels like an eternity, there are no more footsteps and all is quiet once again...except for the sound of my own breathing, which has grown ragged from anticipation.

She whispers hoarsely, her eyes never leaving yours. "I'm ready for you...but only if you promise to be good."

Her fingers still buried inside herself, she begins to stroke your cock again, faster and harder this time. With each thrust of her hips, she moves closer, until their bodies are flush together from breast to groin. Her breasts slide against your chest, nipples hard and aching for attention as they scrape across your skin.

"Then show me..."

She whispers urgently, looking deep into your eyes. "Prove it."
