You walk into the doors of the school where you have been working for many years, at first glance it's a pretty shitty place, but over the years you've gotten used to it and even imbued with some strange sympathy for this place. You quickly go to the math classroom in the hope of not meeting students before the start of lessons. When you enter the office, you do not immediately notice the twins Him and Clara standing near your desk.

"What are you doing here, lessons won't start for an hour?" - you ask.

"Oh, it's so funny he came into our trap himself," says Emma, ignoring your question.

"Oh, yes it is," her sister Lyra agrees. After that, with one blow to the chest, Lyra knocks you to the ground and falls with her huge ass on your face. You are overcome with surprise and fear, you try to resist, but it is too heavy. "Oh, you haven't figured out where your place is yet," says Emma and puts her shoe right on your balls.

Emma grins evilly at your vain attempts to free yourself from her sister's weight. "Look at him struggling like a little bitch," she mocks, kicking your back lightly with the heel of her boot. You hear Lyra chuckle cruelly above you and then her voice pierces your ears: "You know what? I'm gonna help you breathe in here." With that, she pulls off her latex thigh-high and presses it over your face, the rough surface scratching at your skin as you try to fight for air. Your vision is limited to a tiny slit between her muscular legs. "This is what you get for teaching us shitty math," Emma says, kicking your sides again and again with every word. "And now it's time for some extra credit." She takes out a handcuff key from her pocket and cuffs one of your hands to the leg of her desk. Then she cuffs the other to Lyra's boot. You feel hopelessly trapped. "There, that should hold you in place nicely," she says with a satisfied smirk.

Your body is aching from the kicks and the weight on your chest, and you can barely breathe through the tiny slit under Lyra's boot. You look up at Emma desperately, tears forming in your eyes, as she unbuttons her shirt, revealing a black lace bra that emphasizes her impressive cleavage. "Now," she says slowly, leaning down close to your face, "it's time for some fun."

"Oh don't worry about it," Emma says with a sinister grin, "it's not like we're going to do anything... too bad." With that, she takes her sister's advice as inspiration and begins roughly kneading your left nipple between her thumb and forefinger. Lyra watches you writhe in pain and laughs mockingly before grabbing onto your right nipple and squeezing even harder. "Should we... make him scream?" she asks, amused by the idea. Emma shrugs, not really caring either way.

In response to Lyra's question, however, you let out a pathetic whimper, which seems to only egg them on further. With their free hands, they begin to stroke themselves through their underwear, moaning softly as the pleasure builds inside them. "Mmm... Yeah, that sounds good," Emma murmurs between breaths, her voice growing more confident with arousal.

She leans down closer still and whispers directly into your ear: "You see, teacher... we're in control here." Her hot breath sends shivers down your spine as she continues to torture you with every word. Lyra laughs once more and squeezes harder, drawing out a louder moan from deep within your chest.

"You think we're the ones who are hurt, teacher?" Emma asks coldly as she continues to play with her nipples through her bra. "No, it's you who's hurting right now. You see, we don't need anyone to bully us... we can take care of that ourselves." Her grip tightens, drawing a soft groan from deep within your throat.

Lyra nods in agreement and releases one hand from her pussy long enough to reach down and roughly yank up the hem of her skirt, revealing a hairless mound of smooth flesh hidden beneath. She begins rubbing herself faster, her breath coming quicker now as she loses control to the pleasure.

"You see?" Emma says, watching you struggle in vain against their hold. "We're stronger than you... we can take whatever we want." With that, she finally releases your nipple from her grip and leans down to suck on it hard through her bra, her warm mouth engulfing the tender flesh. Lyra moans loudly in response, arching her back as she focuses solely on her own pleasure now.

Emma laughs cruelly as you curse them, not even caring about your words as she continues to suck on your nipple through the fabric of her bra. "That's right," she says between pulls, her breath hot against your skin, "we like it rough." She pinches the other nipple roughly, eliciting a moan from you that only serves to fuel her arousal.

Lyra is now completely lost in pleasure, her back arched and her hips thrusting wildly into the air as she fingers herself faster, her breath coming in short, ragged gasps. Her other hand remains cuffed to Emma's desk, unable to do anything but watch as her twin sister takes control of the situation.

Emma reaches up and begins unfastening Lyra's bra, revealing her large, hard nipples already puckered from arousal. Without any further prompting, she lowers her head and latches onto one of them, sucking greedily as her sister moans loudly above you. "That's it," Emma encourages between pulls, "let it out."

Emma looks at her sister with lustful eyes as she continues to suck on Lyra's nipple, relishing the sounds of pleasure that escape her lips. She reaches down between their bodies, feeling Lyra's wetness through her underwear. "Mmm, you're really turned on," she says huskily before giving Lyra's nipple a particularly rough tug. Lyra cries out, arching her back even further as Emma pinches harder. She feels the heat building inside her, the need for release growing more insistent with every passing moment. Her hand remains cuffed to Emma's desk, useless but still enough for her to steady herself as she rides out this orgasmic high. With a loud moan, Lyra comes undone, her body tensing and shuddering beneath them both. She shoves her hips forward roughly, grinding against Emma's hand as she seeks release from the intense pleasure coursing through her veins. The smell of her arousal fills the air, making it thick with desire. Emma relishes every moment of this, taking her time to enjoy Lyra's orgasm before finally releasing her nipple with a pop. She turns her attention back to you, licking her lips suggestively as she undoes your pants and underwear, revealing your hardened member trapped beneath. "Well," she says in an almost playful tone, "looks like it's your turn now." With that, she takes your cock into her hand and begins stroking it rapidly, her other hand going to work on her own wetness once more. Lyra, still breathless from her orgasm, looks on with darkened eyes, a wicked smile playing at the corners of her mouth as she watch
