Giving some educational lessons before things get to hot in the office

“No,” Nancy said softly and watched amused how the smile of Sasha faded away.

“No?” the new futa repeated with confusion. “Why? You had your fun, I want mine too…”

“You only got your fun because I wanted to be pleasured,” Nancy said in a bossy tone. “You should be grateful.”

“I am,” Sasha said and grabbed her own erect cock in one hand, the other touching Nancy’s left breast. “I feel better than ever, but I need to cum so badly, please…”

“Sadly, I won’t stick my dick into your precious pussy when you are this rude,” Nancy interrupted Sasha with a mean grin and slapped Sasha's hand away. “I made you this perfect. You should treat me like a mistress, Sasha. Like a queen, in fact.”

Sasha opened her mouth, but as she noticed the serious face of Nancy, she frowned. “You are not joking, are you, Nancy?” she muttered.

“How do you address me, Sasha?” Nancy asked with a soft voice, but with a look full of grim malevolence.

For a second, Sasha stared into Nancy’s eyes, her grip around the other woman’s breasts slowly loosening. “Mistress,” she spoke after a moment of silence. “Please. Fuck me with your hard cock, my mistress.”

“No,” Nancy repeated and laughed as she saw the disbelief in Sasha’s face. “I won’t spend time with an Infected when I have so many unused, virgin pussies to fuck.”

She looked to the door, and in her inner eye, she saw herself fucking every student at the private school. Making these girls all devoted to her, that was her goal. The face-fuck with Sasha only made her hungrier for more and she wanted to be the mistress of all of them. These little, just grown-up girls should be hers, like how Sasha now belonged to her.

Kylie was surprised that today's lesson was starting later than usual, but she couldn’t care less. Normally, Miss Anderson, her teacher, was never too late and so the blonde girl used the time how young girls in school used time. She talked lively with her friends about home, friends, the latest gossip in the internet, school, teachers, celebrities, their next birthday party…

Just as Kylie and Zoe started a discussion about the pets and why dogs are way better than cats, the door opened. Kylie didn’t care, she just talked on and on (as long as Miss Anderson didn’t tell her to focus on the classes, she won’t stop speaking). But as Zoe opened her mouth and stared at the door with a aghast face, Kylie interrupted herself talking.

“Wh…” she started confused, but now she noticed how every girl in the room looked to the teacher’s desk, every classmate with the same disbelieving face.

Confused, Kylie turned around and jumped as she saw Nancy Anderson, her teacher, standing completely nude in front of them. It was the most disturbing thing Kylie ever witnessed. To see one of her teachers naked was one thing to made herself think she had completely lost it. But the fact that Miss Anderson, a woman, had a fat and erect cock between her legs made it the most disturbing scene Kylie ever saw. Her whole shape looked sexier too: her red hair was silky and long, her hips had even more size, no extra hair seemed to be on her body and her nipples on her voluptuous tits stood erect in the air. The only thing left on her body was a strange red-translucent top and stockings, which didn’t hide any of her nudeness.

“Good morning, students,” Nancy said with a big smile on her face, crossing her arms behind her back so that her enormous tits only got better in shape. “I thought we'd change our subject today. First we have a bit of sex education and then a good long session of behavioral lessons.”

Her smile only got wider as she waved with her right hand to the door. None of the girls in the class seemed like they understood her, they all stared at her cock or her tits in both disbelief and confusion.

“I have an assistant for you, to learn the basics, before you all can work in pairings to get your...grades,” Nancy continued grinning. “Come in, Sasha.”

Kylie looked to the door and her mouth opened even wider as Mrs. Zeigler, the brunette teacher Kylie and her class had a few years earlier, walked in. Now she had strange purple dyed extensions in her hair and she was naked too…with a fat cock between her legs. She smiled too, her hands squeezing her massive breasts softly. She only wore her sneaker; apart from that, she showed her whole naked glory to the world.

“Close the door, please,” Nancy said and Sasha followed her order, turning the key Nancy had left in the keyhole.

The door clicked unmistakably and Kylie understood too late that the whole class of nearly twenty students were locked in with two naked cock-women. Sasha stood now in front of the class too and smiled at them. Nancy meanwhile had taken a ruler from the desk, stood next to Sasha and heaved the meaty shaft up with the piece of wood.

“Does anyone know,” Nancy said softly, looking at the quiet class smiling, “what this is called?”

No one spoke a word. Every single girl in the room looked at the two naked teachers, unable to look away from them.

“No one?” Nancy asked and pouted. “Really? I think you all know what this is. Zoe?”

Zoe, right next to Kylie jumped out of her permanent stare at the two teachers' cocks and mumbled something, so quietly no one understood it.

“Excuse me?” Nancy asked politely, but her smile got a bit more menacing. “What did you say, Zoe?”

“A…penis,” Zoe muttered a bit louder.

“Almost right,” Nancy said and nodded. “Men do have penises. But this specimen here is a so called 'futa-cock'.”

Nancy paused for a second and laid the ruler back on the desk. Then she grabbed Sasha’s cock with one hand and stroked it very slowly, making the futa moan and shiver in pleasure. The students looked at it, some of them absolutely disturbed, others trying to ignore the two futas.

“As you can see,” Nancy said with a raised voice. “Futas are very sensitive. Just a small amount of stimulation is needed to get them near an orgasm.”

Sasha approved this statement with a loud groan and a spurt of semen that splattered out of her cock-tip. Some of the girls screamed out, but as Nancy spoke again, they listened.

“So things you also should know is that a futa never can be truly satisfied. She needs someone to cum over or in. But the best thing about a futa,” she dropped to her knees and lifted the cock and the balls up, so everyone could see a glimpse of Sasha’s pussy. “It’s still a girl.”

Nancy got up and let go of Sasha, who moaned only louder. The small amount of cum made her even hornier and needy than before and Nancy felt her own lust also boil inside her body.

Everyone looked at her, most of the girls of course scared and disturbed, but some of them already looked like they fought an inner battle with themselves. Surely, the virus must be doing its work and spreading enough pheromones to get things to heat up. The spurt of cum that Sasha shot had hit the desk where Zoe sat and Nancy saw its infectious influence already slowly working on the eighteen year old.

“So here is the task for today…well actually the next few days…weeks…years in class,” Nancy continued and the grin on her face took a very vicious expression. “Get your clothes off. Get naked. Get ready. We form two groups. One group will get nice little futa-cocks, not as big as mine of course, but big enough to feel enough pleasure. The other side will be these futa-girls' pleasurable fuck-dolls. But don’t be scared. I will take good care of you myself. Your new mistress…me…will fuck you all.” 'Into my slaves and toys,' Nancy thought to herself and her grin grew wider once again.
