The teacher has a message for the models

Jessica couldn't believe her luck as she continued to be softly and gently fucked by her friend, in front of an audience of people drawing her.

"How has Emily not noticed?" Jessica asked herself. She glanced over at her teacher and saw she wasn't even looking at the couple.

Moments later, Jessica looked back at Emily and made eye contact with her again. This time, the teacher's piercing stare made it clear that she had seen what was going on, and triggered a shiver through Jessica's entire body, all the way to her pussy that still had her friend's dick inside.

She let out a whimper, hoping to alert James to the fact the teacher was walking over to them again, but he either didn't hear or mistook it for enjoyment as he carried on fucking her.

"Don't worry class, everything is fine," said Emily, causing James to finally realise and stop in his tracks, with his dick just outside Jessica's pussy, "I'm just going to check how our wonderful models are coping with this."

Jessica and James exchanged another scared look. Surely their teacher was onto them this time, and was about to get furious with them.

Emily approached them and stood in front of them, eyeing up the two attractive models in their sex position. Jessica's heart pounded as Emily quickly wrote something on a piece of paper.

"Seems like everything is fine!" said Emily loudly, ensuring that the audience could hear, "Now remember dear models, that we are capturing the moment just before sex occurs..."

Jessica felt her heart sink as the audience giggled, as she was being called out.

"... You've done a perfect job so far, just make sure you stay in position." said Emily sternly and loudly.

The class returned to drawing, but Emily didn't leave yet. Instead, she smiled at Jessica and James and held up the piece of paper, so that they could see it, but the audience would be none the wiser.

The piece of paper had just one word written on it:

HARDER

Emily winked at Jessica, before the girl exchanged an excited look with her partner, and Emily returned to her seat.
