Spontaneous threesome.

It was clear as day we both wanted it. Mila pecked my lips once before she stood up to take off her shoes and white and sky-blue striped panties. And while I was unbuckling my belt, Grace was unzipping my pants like it was the most normal thing in the world.

I lowered my pants and my boxers, letting my dick stand proudly with a racing heart and light head. Grace took it in her hand and stroked it, moistening her lips from left to right and resisting the temptation to gobble it up.

I saw Mila lifting her skirt with one hand and tracing a finger along her slit. She went down to sit on my lap again, then put that same finger close to my mouth. I sucked it, tasting just a bit of her juices on it.

Wet already? From kissing and some dry humping? I’d take that as a compliment.

She leaned closer and whispered in my ear, “Can I put it in?”

“Mhmm.”

Biting her lower lip in anticipation, Mila slowly lowered herself on my cock. Just like that. I felt her pussy’s warmth, squeezing me as she let out a soft moan of delight.

“Ooooh, yes…!”

It lacked foreplay and it was too out of the blue, but that was also what made it great. As amazing as it was to go at it relentlessly in a love hotel, casually doing it in school pushed some very specific buttons.

“Take off my bra,” she told me.

I nodded and got my hand inside her shirt and behind her. I’d seen them all taking off their underwear a few times by now. I could do this. Or I thought I could. As much as my fingers searched for the hook, they couldn’t find it anywhere.

After a few long seconds, Grace couldn’t hold it anymore and started laughing. “Mila, you’re such a bitch.”

“I’m sorry.” Mila laughed with her. “I couldn’t resist!”

“W-What?” I asked, very confused.

My eyes followed Grace’s fingers as they traced the front trim of Mila’s bra and… snapped it open.

“This one unhooks in the front,” Grace told me.

“Oh.”

“I’m sorry,” Mila said, looking a little guilty even as she stifled a chuckle. “Just a little prank.”

I frowned in a pout, and as my **** I gave one of Mila’s nipples a nibble that made her tense up and let out a cute yelp. And yet she wrapped her arms around my head and kept me there to suck on her tit while she started moving, rocking her hips back and forth.

“Mmm! Yes! Suck on them all you want,” Mila moaned.

That was always my plan. Being smothered in her soft chest didn’t stop me from sucking on her nipples and kissing and licking her cleavage to my heart’s content. Call me a pervert for my enthusiasm, but Mila was loving it. I felt so both in my sixth sense and in her tightening pussy.

Beside us, Grace giggled. “God, you two look so cute. You make me a little jealous.”

Mila released me and pulled her chest away, which would’ve been a little disappointing if not for what she did next. This time she was the one who loosened Grace’s tie and started undoing her buttons with one hand.

“And who said you can’t join?” Mila asked, grinning.

Grace blinked, and with those stunned eyes looked at me for confirmation. I put an arm around her shoulders and pulled her closer, kissing her neck. That was all the confirmation she needed.

Grace finished unbuttoning her shirt, threw her tie, panties and bra aside and pushed her massive chest on my face, now smothering me in hers.

“**** by tities,” she said while laughing.

“Worth it…!” I answered in a muffled voice. Thank God they both found that funny.

Thing was that now I had to multitask. The prospect should’ve terrified me, made me fear that I wouldn’t be able to satisfy them both. But I was confident this wouldn’t be difficult. It wasn’t my first time, now that I remember. We’d done something like it in the P.E. storage room.

Grace sat comfortably beside me again. I put an arm around her waist and snuck my hand under her skirt. I made out with her while I easily slid a couple of fingers inside her pussy. She stiffened and shuddered, holding my face with both hands and kissing me harder.

At the same time, I made sure to move my own hips at a quick pace. Mila pressed her lips to try to muffle her moans and gasps, resulting in heavy nasal breathing. Her grip on my shoulders also tightened. She moved to try to match my pace, which made her tits bounce all over the place.

A girl in each arm, one riding on top of me while I fingered the other. Their voices in my ears, going crazy from pleasure. The heat oozing from their bodies and clashing against mine made it seem like the temperature of the whole room was rising. And what room was it? An old, unused music room in our own school of all places.

I was so fucking turned on it was insane. My dick throbbed inside Mila’s clamping pussy. I devoured Grace’s mouth with hot, sloppy kisses that she returned with equal passion. I sunk my fingers in the supple flesh of their breasts, having to take turns since my other hand was too busy attacking Grace’s G-spot. How did I know I had the right spot? I simply did.

But it wasn’t all instinct now, as it was before. In my short time with them, I had become more familiar with their bodies. I knew which places they liked to have touched, which places felt the best, and in what ways.

I broke my kiss with Grace to suck on Mila’s nipples. She hugged me close when I did and whispered in my ear almost out of breath.

“I’m so close, Oliver. So close! Fuck me!Fuck me!Fuck me!”

Grace moved closer and whispered in my other ear, her own voice shaky from pleasure. “Come inside her, Oliver. Mark her.” She nibbled my earlobe. “She loves it. She wants to feel your cum sloshing inside her. Give it to her.”

Their voices, their breathing in each of my ears added to every other sensation. In only a few more seconds, Mila came on top of me, pussy quivering, body shaking and holding onto me tightly. I didn’t stop moving my hips, and Mila didn’t want me to.

Grace came from my fingers not long after, biting onto the shoulder of my school jacket. She grunted and groaned with eyes closed, mind numb from the intense orgasm.

A few moments later I reached my own peak, letting everything out. A thick load filled Mila’s pussy, and as if she was waiting for it, she immediately came a second time. She hid her face on my left shoulder while Grace rested her head on my right one.

We basked in the afterglow of our orgasms. Silent, close, blissfully relaxed. It was a magical moment. A spontaneous threesome before class started, and with enough time left to enjoy the peaceful moments after it. Nothing could ruin it. Except the door suddenly opening. What did you expect?

My heart jumped to my throat, and I knew the same happened to Mila and Grace. We were violently snapped back to reality, and with panic turned to the door to see with horrified expressions who had caught us.

“So you’re done. Good,” Sarah said, casually walking in, closing the door behind her and, in a genius play, locking it from the inside with the latch.

Unspeakable relief washed over us. My heart was still beating unhealthily fast, but it was slowing down. I never thought I’d be even happier to see Sarah than I normally was. I think I was the only one to feel that way, though.

“Sarah, what the fuck?” Mila cursed. “Almost gave us all a heart attack.”

“What? You would have rathered I came in while you were doing it and totally ruined the mood? I was waiting outside for like five minutes. By the way, this room really does isolate the sound perfectly. Even standing outside I didn’t hear a thing with the door closed.”

“Thank god it was you,” I told her, laughing nervously.

Sarah chuckled, amused.

Catching her breath, Grace let out a long, drawn out sigh. “Aren’t you a little late? What happened?”

“I went to open up shop, like always, but one of the employees dropped some boxes and left a bit of a mess, so I stayed and helped. You’d know that if you checked your phones, but you clearly were too busy to bother, huh?”

We all checked our phones. Sarah’s message was there.

“Clearly,” I echoed in shame.

“Was tempted to join, but judging by this reaction, you were so into it I would’ve just ruined it. Good thing I waited. I even sneaked a peek and you didn’t notice.”

Mila, Grace and I let out a sigh in unison. There went all the blissful relaxation, but it was infinitely better than being caught by anyone else. Next time, lock the damn door.

Yes, there would be a next time. This wouldn’t be a lesson we’d learn.
