"Hey, babe, whatcha doin'?" Karli asked as she sauntered into my bedroom. I smiled up at her from my bed, putting my book down. She knelt and gave me a kiss on the cheek, something one would expect from girls who had been besties for a long time.
"Namuch, just the stupid calc homework." I replied. "I hate this shit."
"Ugh, you and me both," she agreed as she flopped down on the bed beside me, staring at the ceiling. "Absolutely the wrong way to be spending my summer, doing extra courses for credit."
"So, you and Jer are not having fun anymore?" I posited, smirking at her.
"Nope, he turned out to be the dud you warned me he'd be," she sighed. "I mean, his dick was alright, but he was turning into a little drama queen. Who's got time for that crap? The fucking wasn't good enough to make it worth putting up with."
I giggled at her discomfiture. We didn't have any online lecture classes on Tuesdays, so I'd elected to catch up on my studies in my room, rather than head across town. I frowned as I noticed her outfit. "What's with the nostalgia?"
She half-sat up and grinned, waving a hand in front of herself as if I had never seen it before. It was our old high school dress uniform, complete with blue blazer and pleated tartan skirt. "I just wanted to see if I was still sexy in it, so I wore it around."
I laughed. "You're such a huge slut. And yes, you still look hella sexy in it."
"You don't think my boobs are too big for it?" she asked, indicating her bust, the top of which was swelling out of the tight white shirt. She clearly couldn't button the blazer anymore.
"It's only an improvement if they are," I said soothingly. "Remember how baggy the uniform was when we first tried it on?"
"Yes," Karli muttered somewhat darkly. "Took me forever to get a boy to fuck me because you couldn't see my body underneath all the material."
"Never stopped me." I said softly, looking at her slyly.
"Well, you always were my favourite fuck all through high school..." she purred as she knelt in front of me, her eyes warm with desire. She gazed up and down my body- I was wearing a long shirt as a nightie, with some panties underneath. She took hold of the hem of the shirt and I lifted my behind slightly, allowing her to wiggle it up to my hips.
"Got some urges that need looking after?" I breathed, suddenly feeling the flush of warmth that accompanied arousal. Math could wait. Fucking Karli now took precedence.
"What can I say, you bring out the lesbian slut in me," she replied, sidling closer on her knees. "I didn't even plan to fuck you when I stopped by, but seeing you splayed shamelessly on your bed like this just got me going."
"Well, who am I to trivialize your needs?" I moaned as she leaned in and kissed me, her hands on either side of my torso now. I was propped up on a few pillows, so we were face-to-face while she knelt. Lips parted and tongues tangled in an intimate and familiar greeting. The flush of warmth over my skin made me acutely aware of how wet I was quickly becoming. I could feel her breasts bump into mine as the confines of her white school blouse failed to contain them.
"God, I love your tits," I whispered through our kiss as I reached up and cupped them gently through the material of her shirt and bra. "They're so damn big now."
"Just like yours," she murmured back, pressing closer to me. "Remember sneaking into the developing room in the arts wing and rubbing them together?"
I shivered at the memory, grasping her breasts harder. "Shit, yes, but... do you have time to fuck? Don't you have your weekly lunch with your mom in an hour?"
"We'll make it a quickie," she said, finally breaking the kiss as she reached down to lift her skirt. "It'll gimme something to think about while she blathers on about work and whatever cute new boy in the office caught her eye."
I loved Karli to death, but it was fairly obvious where she got her free and easy attitude concerning fucking from- her mom was, or at least would be if she took care of herself, a cougar, always on the prowl since her most recent divorce. The problem was, she was not working out or maintaining her body, so fantasizing was likely all she had left.
Not so with Karli. Her daughter was smoking hot and made me so damn wet. "So what do we want to do, then?"
"It's been a while, but..." she murmured. She knelt close to me and pulled my hips close. She pressed her panties to mine and began rocking back and forth. There was already a small wet spot on our panties and they were growing.
"Mmmmm..." I moaned as she leaned in and kissed me again, taking her face in my hands. We squirmed our panty-covered pussies together, feeling our gooey lips meeting through the sticky fabric. We'd done this countless times before, something quick and easy to do with little evidence of our misbehaviour. We'd done it at school more times than I could remember, pulling one another into empty classrooms, locker rooms or just the janitor's closet, lifted our skirts and squirmed our cunts together until we came.
"Fuck, you feel so good," Karli whispered through the kiss. "Gimme your tits..." She hiked my nightshirt up even farther to expose my breasts, while I undid her bra and pulled her shirt off, freeing her tits from their confines completely. With a shiver and a gasp, we pressed together hard, nipples poking and brushing over one another.
I ground my hips in circles against hers, watching as the wet material of our panties clung together. I could feel her pussylips mushing against mine through the underwear, the sensation sending thrills through me as we fucked.
She reached under my behind and pulled me closer until I was in her lap while she knelt. I wrapped one leg around her waist, keeping my puss pressed against hers while we writhed. Our mouths met hungrily and tongues plunged as we kissed. My hands roamed over her back and down to her ass cheeks while she caressed mine with increasing fervour. It felt so good to be fucking Karli again, it felt like forever, even though it had only been two weeks, at most. We were never too busy to fuck one another.
She tossed her head back and panted as she ground and squirmed against one another, not trying to prolong anything. We just wanted to cum together, as quickly and as hard as possible. Warm sweat was forming on our bodies and we began to tremble, feeling the exquisite buildup.
"Fucking fuck..." she grunted through clenched teeth as she pressed her cunt harder into mine. "Gonna cum so hard!"
"Me too!" I panted, meaning it. My body was on fire and I would have to work hard not to scream as I came. "Cum with me, Karli!"
The floodgates opened and we kissed in a frenzy, screaming into one another's mouths. We pressed our pussies together so hard I thought our hips would crack from the pressure. I could feel our warm cum soaking our panties and mixing together between us. We rocked and ground with abandon, desperate to feel every single sensation of delight crackle through us.
We both fell backwards, panting heavily, our legs still locked, panties glued to one another. I gently caressed my breasts, bringing myself down from the incredible sexual high. I could feel Karli trembling still. I loved watching her cum, since she always looked like she was having a seizure made of pure pleasure. My own orgasms, while equally powerful, were not quite so visually dramatic.
"Holy shit..." she said breathlessly, still on her back. "That was a good one. Panty-fucking always did give us amazing orgasms, didn't it?"
I nodded. "I've tried it with other girls and it's great and all, but never as good as it is with you."
"Mmmm, good to hear," she purred as she reached down and stroked our sopping panties. "God, I love that..."
We stayed like that for a few minutes more before getting up and cleaning ourselves off. Karli hadn't brought any spare panties, so she borrowed one of my pairs, but not before insisting I wear them for a few minutes so I'd be with her during lunch.
I was putting on a fresh pair of panties when I noticed her looking out my bedroom window and into the garden beyond. Something seemed to have her attention.
