Substitute Teacher

Mike had agreed to help Jacob fix his poor grades. He expected to have tutoring sessions, but Jacob's plan was a lot more straightforward. After school, when the real Mrs King had left, they snuck into her room. To avoid getting caught, Jacob went to check the coast was clear. Before he left, he used a magic totem to turn Mike into Mrs King.

"What the fuck did you do to me?" Mike asked through gritted teeth to keep quiet.

"It's just in case someone comes by here while I'm gone." Jacob explained. "I figured you'd prefer it if no one could pin this on you."

"True... But what the hell am I supposed to do in her body?" Mike sighed.

"Whatever you do, don't play with yourself!" Jacob replied firmly. "A side effect of this totem is that it makes the user incredibly horny, but you can't give into it, okay?"

He ran out of the room before Mike could ask anymore questions. Mike looked down at Mrs King's tits and lightly bounced in place.

Entranced by the bouncing masses on his chest, he didn't notice as Grant; the asshole jock, crept into the room.

"Are you having fun, Mrs King?" He smirked.

"Grant! What are you doing here?" Mike gasped, covering his breasts instinctively and feeling a jolt of pleasure as his arms rubbed against his nipples.

"You confiscated my magazine, remember?" Grant sneered. "But I'm glad I managed to film you bouncing those tits around! It's the perfect blackmail."

Mike's eyes went wide. That video couldn't go to anyone! If it did, it'd spread like wild fire and Mrs King would soon work out that someone impersonated her. Whatever Grant wanted, he had to make sure he did it for him. To make matters worse, Grant was more than a little sex driven.

Grant moved uncomfortably close to Mike and placed his hands on Mrs King's waist. Mike felt another tingle of arousal and pleasure and quickly realised that Jacob's warnings were true. He was getting horny. His breathing became more laboured and his heart started racing. Grant could tell that he was aroused by the way Mrs King's chest rose and sank with every deep breath.

"I never knew you'd be this horny, Mrs King." He smirked.

"I'm not-!"

Before Mike could explain who he really was, Grant moved in for a kiss. There was more passion in that kiss than Mike anticipated giving back. Two sets of hands began exploring each others bodies, as they moved towards the wall. Mike gasped in pleasure as his back hit the wall, pinned against it by Grant.

"What would your husband think, Mrs King?" Grant snickered.

"I... I don't have a husband..." Mike replied, flustered by the unexpected waves of pleasure.

"If that's what you need to believe right now, I'm happy to go along with it." Grant nodded. "How important is that video to you?"

Mike's eyes flickered for a moment as he slowly snapped himself out of the moment. He still felt incredibly horny, but managed to bring himself to push Grant away. They looked at each other for a moment. Mike couldn't help but notice the bulge in Grant's pants.

"Like what you see?" Grant smirked.

"No! I...I... I think it's best that you leave, Grant..." Mike stammered.

"Are you sure? Maybe you'd change your mind if you saw this!" Grant sneered, pulling down his zip and undoing the button of his jeans.

"What are you doing!?" Mike gasped, unable to look away from Grant's cock.

"It's simple really, Mrs King..." Grant smiled. "Either you finish what you started... Or I'll send that video to the principal and tell him you tried to seduce me!"

Mike was lost for words. This was all going way too far. He couldn't let Mrs King get into trouble for this. Not only could she lose her job, but people could start to question and look into the magic totem. There was only one way of eliminating this evidence. And the entire time he was deliberating this, he had been staring at Grant's cock.

"You need to promise me that this will only be a one-time thing!" Mike said firmly.

"I'm not gonna lie, Mrs King, this won't be the only favor I ask of you." Grant smirked. "But I promise that that video will be deleted. I'll even let you do it yourself, once we're done here."

A slight smile spread across Mike's face. The thought of Grant approaching the real Mrs King later in the week and trying to blackmail her with no evidence was amusing. Once that video was gone, he'd have nothing to back up his story and even Mrs King would have no idea what he was talking about.

"Okay... I'll do it." Mike nodded. "W-Where shall we start?"

"How about you crawl across the table and wrap your mouth around this?" Grant sneered, pointing down his cock.

It was disturbing to be in this situation, but made worse by the fact Mike wasn't bothered by the thought of sucking Grant's cock. It was as if the rising female arousal he had felt while looking at it had conditioned him to like cock, this cock.

"I knew you were a slut at heart, Mrs King!" Grant smirked, as Mike climbed on top of Mrs King's desk.

"Would you just shut up and let me get through this!?" Mike snapped. "Bad enough that I have to do this. I don't want to hear your stupid comments!"

"Well your mouth will be busy in a second, so my voice is all you're gonna hear." Grant spat. "Unless you want me to send that video to a friend of mine?"

Mike had to bite his tongue. Grant was pissing him off more than usual, but he held all the power right now. Anymore back chat and Grant would send that video. So, swallowing his pride, Mike kept his mouth shut and crawled across the table.

"Tell me you want to suck my cock." Grant ordered.

The worrying thing was that Mike kind of actually did want to suck this cock. Being in Mrs King's body, with the rising arousal, had made him curious about what this body could feel. Would he enjoy giving another man head? Jacob had warned about giving in to the arousal, but there weren't many other options.

"I... want to suck your cock, Grant." Mike said slowly.

"With feeling!" Grant sneered.

But Mike decided that actions would speak louder than words. He quickly grabbed the cock in his hand and lowered his head down onto, taking it in his mouth. He did it partly to avoid begging for Grant's dick, but mainly to try and quell this arousal. The longer he waited to suck Grant's cock, the wetter he felt between his legs.

"Holy fuck!" Grant gasped. "You really are a slut!"

The heat in the classroom was growing unbearable. Mike started taking Mrs King's clothes off in hopes of cooling down, but the more flesh he put on show the hotter he felt. He was only encouraging Grant to go further and further. Soon enough, Grant was naked and had his hands on the back of Mike's head.

"Take it all in, Mrs King!" Grant grunted. "I want to cum down your throat!"

They continued like this for some time, until Grant finally released Mike's head and went to grab his phone. Mike didn't even notice as Grant took a video of him expertly sucking his cock.

"Here it cums, slut!" Grant groaned.

The door opened just as Grant came inside Mike's mouth. Jacob watched in horror as Mike willingly took the load of cum and even giggled as the last jet hit his face. He had given in to the arousal completely and there would be no going back to manhood now.

"Hey, Jacob!" Grant smirked. "You're just in time for some sloppy seconds."

Jacob didn't even respond, instead locking eyes with Mike. He was gonna have to use the totem to change Mike into a completely different woman. And now that Grant had videos of 'Mrs King' sucking his cock, he'd need to disappear too...
