I grinned as Kathy stumbled into our 10 am physics lecture with her hair slightly disheveled and the slight smell of arousal lingering around her. Evidently, she had enjoyed the trigger I'd given her. She sighed happily as she sat down, and I wrinkled my nose slightly as a sweet, fishy smell assaulted my nose. Maybe she had enjoyed it a little too much.

"God, Kathy. Wash your juices down with some water next time. You smell like you just left a lesbian orgy."

Kathy rolled her eyes but grabbed her water bottle and took a gulp of water, swishing it around her mouth as she grabbed her notes. She wiped her mouth on her arm, yawning as the professor started up his slideshow.

God, even by 10 am standards, this class was a fucking drag. Kathy wasn't even paying attention anymore, snoring softly with her head tucked into her chest and her mouth open. As I watched her peaceful sleeping face, I felt the urge to mess with her.

"Kathy, you're having a very erotic wet dream."

I leaned towards Kathy, whispering my suggestion into her ear. She twitched for a moment, scrunching her eyes before relaxing again. A satisfied smile crossed her face as her nipples hardened, poking out slightly against her bra, just enough to be noticeable.

Her breaths deepened as her lips parted, slick with saliva. Her panties were damp, pressing against her black leggings as the smell of her arousal wafted up to me. Kathy moaned softly as she shifted, rubbing her thighs together and gasping before falling still again.

"Your lips are wrapped around a hot, girthy cock. You can feel it stretching your mouth open."

Kathy blushed a deep pink as my suggestion took effect, letting her jaw slack open even further as her tongue flopped out of her mouth. A strand of drool hung on her tongue before dropping onto her thigh, adding to the growing wet patch in her leggings. She let out a loud gluck sound as she swallowed, shifting her ass again as her blush deepened into a dark red.

"Feel how that cock is throbbing in your mouth, filling you with an enormous load of cum."

Kathy squirmed, quickly licking her lips as she closed her mouth, puffing up her cheeks. She frantically swallowed thin air, her throat pulsing and her head bobbing as she swallowed the imaginary cumshot. With a loud gasp, she finally opened her mouth, quivering as her head fell forward again. After a few seconds, her gentle snoring resumed, as if nothing had happened at all.

"...That's all for today, class. See you tomorrow morning."

I nudged Kathy awake, biting my lip to stop myself from smirking as she awoke with a guilty start, gasping as she shot up, panting heavily as she looked around. She licked her lips, rubbing her hand around her jaw as she looked down at herself.

As I stood up, motioning for her to hurry up, Kathy rubbed her thighs together, looking around nervously before quickly getting out of her seat, trailing behind me as she adjusted her leggings, trying to hide the moist stain that had formed near her crotch. I glanced at her seat as Kathy jumped out of it, noticing the wet imprint of her ass that she had left behind. I feigned ignorance as Kathy gave me a suspicious look, squeezing her hand in mine as we walked to our next class.

"So... I have a feeling you're responsible for this stain, Trey. And this taste in my mouth."

"Guilty as charged. Don't say you didn't enjoy it, though."

"Mmm, it was a nice dream. We're not doing anything important in class today, right? Up for part two?"

"You're a real slut for being hypnotized, huh? So desperate for me to take over your mind~"

Kathy blushed and smirked, biting her lip as she rubbed her thighs together, letting out a shaky breath as I teased her. She gulped as she squeezed her hand around mine, shivering as she followed me into our next class. I made a beeline for the back of the lecture hall, far enough away from the rest of our class to avoid attracting too much attention. Kathy winked as she got into the seat next to me, theatrically yawning and closing her eyes.

I traced my hand along Kathy's thigh as the professor fired up his slideshow, feeling the moist cloth rub against my fingers as I grabbed her leg, squeezing it as she fidgeted and held back a moan.

"You're feeling very sleepy now, Kathy. Sleep..."

Kathy's breaths slowed as her jaw went slack, her face relaxing as she dutifully followed my suggestion. Her soft, supple lips parted as she snored quietly, her chest gently rising and falling with every breath as she plunged into a deep slumber.

"Good girl. You're having a wonderful wet dream again, right where you left off last time. But now, your pussy's being filled with that cock instead."

Kathy slumped into her seat as my suggestion took hold, wiggling her hips as her pussy was penetrated by an imaginary cock.

"That's right. Feel that cock stretch open your cunt, pressing against your womb. Feels good to be filled, doesn't it?"

Kathy blushed and shuddered, her arms falling in her lap as her head lolled to the side. She whimpered in her sleep as she wet her leggings again, and I could see her delicate mound clenching through her soaked panties.

"Yeah, you like that, don't you? There's another cock plunging into your ass, taking turns with the one in your pussy, thrusting in and out and in and out."

Kathy moaned, slumping against the desk as she clenched her thighs around my hand, trapping it between her moist leggings. Her hips bucked against the seat, making it squeak with every thrust she imagined. As Kathy squirmed, I checked the clock on the wall. Still another thirty minutes to go...

Kathy twitched and mumbled under her breath as the next half hour slowly ticked by, getting wetter and wetter with each passing minute. The smell of feminine arousal was starting to get really strong, wafting up to me from Kathy's crotch as she shifted again, squelching against her seat. Thank god I chose this spot, otherwise, Kathy would be fucked and not in a fun way.

I carefully nudged Kathy awake as the professor dismissed us, stealthily clamping a hand over her mouth as she moaned, clenching her hands around her seat until her knuckles were white. Her warm, moist breath coated my hand as she panted into it, rubbing her pussy through her panties as she finally escaped the dream I had trapped her in.

"Oh god, ohgodohgodohgodohgodohgod... fuck, my body is on fire right now. I can't even fucking feel my legs."

"Shit, do you need help, babe?"

"Y-Yeah, please. J-Just hold me so I don't fall. Ohhhhhh godddddd~"

I grab Kathy's hand in mine, clenching it tightly as she weakly picked up her backpack and slung it onto the back. She stumbled out of the classroom on trembling legs, panting as she held onto my hand. She nudged me towards the bathroom, pointing at her leggings as she rushed inside.

Kathy came out a few minutes later wearing a fresh pair of panties and another pair of leggings, looking refreshed as she grabbed my hand again. We had some time before our final class of the day, so we decided to walk to the dining hall for lunch. Kathy and I sat down with paper plates of pizza, nudging my crotch with her legs under the table, smirking as she saw me huff in response.

"Heh. Enjoying yourself? I definitely did this morning."

"Unfff. You're such a tease, you know? I'm gonna destroy you this weekend."

"Looking forward to it~ Ooh, that reminds me. I've been talking with Ivy, and she wants to have a little bit of fun as well. You don't mind, right?"

"Of course not! But... Are you really ok with me fucking another girl?"

"Yeah. And, um, well, I kinda want to see you corrupt Ivy."

I grinned and shook my head as Ivy blushed and took a bite of pizza. If that's what she wanted, I was more than happy to deliver. I grabbed my pizza as Kathy took another bite of hers, smirking as I wiped some sauce off her face. God, I was fucking lucky to have a girlfriend like her.

We made casual talk for the rest of lunch, laughing and eating our pizza as we talked about nothing in particular, just joking around and eating. We threw our plates in the trash as we got up to leave, holding hands as we slowly moved to our final class of the day.

"So, you just keep extra clothes in your backpack, or?"

"Yeah. Long story."

"We've got a few minutes before we get to the Math Building. Come on, tell me. Is it embarrassing?"

"Yeah, sort of. I... I might've pooped myself in fourth grade on the way to school. I don't think I've ever cried as much as I did that day."

"No way. You're joking, right?"

"Can't lie, remember? Wish I was joking. I can laugh about it now, but I got called poopypants for the rest of middle school. So, I just carry extra clothes with me wherever I go. I know it's dumb, but it just makes me feel antsy whenever I don't."

"Wow. That's, like... villain origin story levels of crazy. But they were pretty useful today, at least."

I laughed along with Kathy as we walked into the classroom, taking our seats as class started. Kathy seemed pretty worn out from this morning, so I decided to take it easy on her, letting her spend the hour without messing with her. Normally, it would've taken a fair bit of willpower to keep me in check, but since there were other people next to us, I just relaxed. No point risking anything just for a few minutes of fun. Even though I could probably hypnotize them and make them forget...

Agghh, I needed to stop thinking like that. Ever since I managed to hypnotize Ivy yesterday, I'd been wondering nonstop what it'd be like to hypnotize someone besides Kathy. I shook my head to clear it, turning back to my notes. Still, the thought lingered in my head for the rest of the lecture, and I let out a sigh of relief as Kathy and I stood up to leave. Hopefully, Ivy would be pretty chill this weekend, and I'd get to try some new stuff with her and Kathy.

I slid my hand out of Kathy's grasp as I got into my car, throwing my bag in the back as I pulled out of the parking lot. Kathy pulled out her phone as I stopped in traffic, humming to herself as we waited for the cars in front of us to move. She gave me a curious look as I leaned over, whispering in her ear.

"Hey, Kathy. Whenever you see a red light, your arousal will double."

Kathy's eyes widened, and she glanced toward the light in front of us, shakily exhaling as she noticed the color. She grinned as she looked back at me, putting away her phone as her nipples stiffened up, pressing against her shirt. She rubbed her thighs together as the light turned green, keeping her eyes firmly on the road as we drove back to our apartment.

"Never thought I'd actually want to see a red light... Mmmhhhhff, fuckk."

Kathy groaned as we stopped at another red light, doubling over as she brought her hands up to her boobs, rubbing them through her shirt. Another few red lights later, her shirt had come off, and she was breathlessly playing with her tits, pinching her nipples between her fingers as she moaned loudly, leaning back in her seat with her mouth wide open.

By the time we got back, Kathy was a drooling, senseless mess. I had to help drag her out of the car, carefully pulling her shirt and bra down as I helped her out, letting her lean on my back as her trembling legs gave out on her. She rubbed her body against mine as I helped her up the stairs, moaning deliriously as I brought her to her apartment. Her hand shook as she unlocked her door, stumbling inside and managing to walk for a few seconds before faceplanting onto the couch. She groaned loudly, tugging at her leggings as she peeled them away from her slick thighs and wet panties.

"Fuckkk, I'm so fucking horny right now. You better let me cum, Trey. I swear to god, if you keep me like this..."

"Oh, really? What are you gonna do if you don't get to cum."

"You wanna find out? Y-"

"Kathy, you can cum now."

"OOUGHHHH! FUCK! CUMMING!"

Kathy bucked her hips against the couch as she rubbed against it and her tongue drooped out of her mouth as she lost control of her body, unable to do anything but moan and yell in ecstasy. I gave her ass a smack, squeezing her cheek before closing the door and leaving Kathy's apartment.

Just a few more days until the weekend rolled around.Then, I'd get to mess around with Kathy and Ivy as much as I wanted...
