Why she keeps going of course.

Maybe if she was quick they wouldn't realize what she and Jean had been doing. It was a vain hope of course, anyone could see plain as day what they were doing, but it was all Isabel had. She tried to lift herself, roll onto her side and off the table where she could hide, only her limbs still wouldn't move. Pinned and helpless she could only watch in horror as more students poured in.

“Let me up! Please... we have to hide!” Panicked, Isabel's whisper came out loud enough for anyone to hear. And yet, no one was reacting to her. They just filled in and took their seats, looking as bored as any student might at their last class of the day.

“Shh.” Jean grinned down at her, one finger pressed to her lips. Silken warmth surrounded Isabel's shaft as the older woman sank down onto her, right there on the table in front of the whole class. No one so much as looked up, not even when Izzy let out a shuttering moan.

'You didn't Emma was the only one who knew that trick did you?' Warm laughter filled Isabel's mind. Out loud, Jean started to speak in a carefully controlled voice. “Good afternoon class. Everyone please take out last night's assignment and pass it ahead of you. Kitty, if you'd be so kind as to collect them?”

The sound of rustling bags and zippers unfastening filled the room, along with a light slapping that was slowly building in speed. Jean rolled her hips in a slow, deliberate pace, sliding up to the tip of Izzy's cock until she'd almost slip off, then crashing her weight back down. She gave a long satisfied sigh as she caressed her hand slowly up her chest.

“Here you go.” It was the brown haired girl Isabel had seen in the common room just before. She was holding out a stack of papers for Mrs. Grey to take, and had been for a while.

“Yes, good girl.” Jean practically purred the words.

“Uh, okay. Thanks?” Looking thoroughly uncomfortable Kitty gingerly set the stack of papers onto the table, barely missing Isabel's ankle. They were already starting to edge off of the table by the time she returned to her seat.

“Last week we left off with...” Even while Jean started to lecture for her class she kept on bouncing herself on Izzy's cock. Her facade was slowly slipping away, her breathing getting heavy and her speech coming out in gasps. From the perplexed reactions of the class she wasn't able to completely hide the irregularity either.

By this point Isabel was beyond caring if she was exposed. The warm squeeze of Jeans sex and her constant rhythm had easily pushed her past the point of no return. She tried to hold herself back, not wanting the feeling to end, but the tension was getting overwhelming.

“Ms Grey...” Strained with pleasure, Isabel tried to keep her voice to a whisper in case the students could still hear her. “I'm gonna come.”

“Good girl, don't hold back. I want every last drop inside me. My husband and I are trying for a baby, so I want you to fill me up.” Something was off about that, but at the moment Jean couldn't quite place what it was.

Her restraint snapping like a twig at Jean's command, Isabel shuddered and arched her back. Pleasure **** her breath out it quick panting gasps as her cock pulsed with release. For all her frustration and humiliation, she found she was grateful to be a mutant in these rare moments when she was finally able to come. Ropes of fresh warm seed pumped out of her, filling her teacher just as she'd been asked.

Feeling her student climax Jean pushed herself down fully onto her shaft, making sure that not a drop would be wasted. She hadn't come herself yet, but she'd make sure to get her own tonight when she introduce Isabel to Scott. Right now it was about taking care of the girl.
