Monday.
Very early.
The college gates were still half-shadowed when the original ten arrived as a single glowing unit—Leah, Sophie-Anne, Mia, Chloe, Emily, Hannah, Grace, Lily, Ava and Ruby. They had already been used once at home by free-use family and once more in the car park by two impatient parents who “just happened” to be dropping off younger siblings. Milk still beaded faintly under their blouses. Centaur-pre-cum bottles sat in their bags like holy relics. Their kinks were awake and humming.
They were waiting for the twins.
Isla and Freya came from one direction, Maya and Zoe from the other, all four still flushed from Sunday’s birthday railings, all four walking a little carefully because parents and older siblings had kept them full until midnight. They looked confused to see the entire birthday cohort already there, lined up like a welcoming committee twenty minutes before the site even properly opened.
“Uh… morning?” Isla offered, glancing at the still-quiet building. “Why are you all so early?”
Freya nodded, shifting her bag. “We only just turned eighteen yesterday. Did we miss a message?”
Maya and Zoe exchanged the same slightly wary, still-horny look. The scent rolling off the ten was stronger than anything in their houses—vine, teacher cum, parental milk, pure free-use need—and it made their brand-new adult bodies clench and dampen instantly. They didn’t fully understand why yet. They only knew they were suddenly dripping again.
Leah stepped forward with a bright, locked smile and linked her arm through Isla’s.
“Extra credit,” she said simply. “From the teachers. Now that you’re eighteen.”
Sophie-Anne took Freya’s arm. Mia and Chloe claimed Maya and Zoe the same way. The rest of the ten closed ranks around them like a living escort.
“Special pastoral programme for new legal students,” Chloe added, eyes sparkling. “Staff room. Right now. Trust us.”
“It’s… mandatory,” Emily said, already steering them toward the side entrance the principal had left unlocked. “New responsibilities of being eighteen at this college. You’ll understand in about five minutes.”
The twins let themselves be led. The scent was too strong, the ache too sudden, the ten too confident and glowing. Something in the absolute age already whispered that resistance was pointless and joy was waiting.
They crossed the empty courtyard, slipped through the staff-only door, and walked straight into the staff room.
The door locked behind all fourteen of them.
The Staff Room Initiation
Every free adult who could be spared was already there.
Mr. Hale. Ms. Patel. Mr. Grant. Mrs. Shaw. The principal and deputy. Mr. Callahan. Mr. Okonkwo. Ms. Rivera. Half a dozen more teachers. Three of the most impatient parents who had been fucking the original ten all week. The air was thick with milk, cum, and open hunger.
The original ten didn’t give the twins time to speak.
“Welcome to free use,” Leah said, already unbuttoning Isla’s blouse. “This is the real extra credit.”
Clothes came off in a coordinated wave. The ten stripped the twins with practised, affectionate hands—blouses, skirts, bras, knickers—until Isla, Freya, Maya and Zoe stood naked and dripping in the centre of the staff room, tits already beading milk under the scent, cunts shiny, eyes wide with the last of their confusion.
Then the initiation began properly.
The original ten paired off with the twins and demonstrated.
Leah bent Isla over the same coffee table she herself had been claimed on and nodded to Mr. Hale. He slid into the new eighteen-year-old in one long thrust while Leah held Isla’s hair, kissed her, and whispered, “This is what teachers are for now. Free use. Any time. Any hole. Happy birthday, late.”
Sophie-Anne sat Freya on Ms. Patel’s face and latched onto one of Freya’s new milk-tits at the same time, milking her while the English teacher licked. “We get milked. We milk them. We fuck them between lessons. You will too.”
Mia and Chloe tag-teamed Maya with Mr. Grant—rough the way Mia liked it—while explaining between moans that parents of younger students would also slip in to use them until their own kids turned legal. Emily cuffed Zoe’s wrists loosely with the soft theatre ties and let Mrs. Shaw and an impatient mother rotate through her, showing her the restraint kink in real time. Hannah made Freya (passed over after the first round) recite “I am free use for every adult in this building” while the principal fucked her throat. Grace took Maya in a proper double with the deputy and one of the fathers, teaching her how good two at once felt. Lily wrote NEWLY LEGAL – FREE USE across Zoe’s belly in marker and made her stand on display while three staff used her. Ava simply placed Isla on her hands and knees under the table and let anyone who wanted a hole use her like furniture. Ruby held Freya open and watched man after man breed her, cooing, “Keep it all in. That’s your new job. Stay full.”
The original ten didn’t just watch. They joined. They scissored the twins, fed them milk, licked cream-pies out of them, held them open, praised them, degraded them gently, and came with them. Every kink the ten had discovered over the previous week was demonstrated on the twins’ brand-new legal bodies until the four of them were shaking, milk-spraying, overflowing with cum, and laughing through the last of their shock as pure understanding and joy rewrote whatever confusion remained.
Internal monologues shattered and reformed:
I’m getting fucked by my history teacher while Leah holds me and it feels like the only thing I’ve ever wanted—
Ms. Patel is drinking my milk and I’m drinking hers and the ten girls are all free use and so am I—
There’s a parent I don’t even know breeding me and Ruby is telling me to clench and I love it—
This is the extra credit. This is being eighteen. This is forever.
By the time the first registration bell rang in the distance, the two sets of twins were fully initiated—marked, claimed, kink-awakened, and glowing with the same permanent free-use hunger as the original ten.
The principal stroked four sweaty, sticky heads and spoke the new rules aloud so every twin heard them while still full of cock or cunt or milk.
“You are now part of the birthday free-use cohort. Teachers first. Then any locked adult who wants you. Parents of under-eighteens will keep using you until their own children become legal. You will help claim every classmate the hour they turn eighteen. Three more students in your year hit eighteen this coming week—one on Wednesday, two on Friday. You fourteen will meet them at the gates the same way you were met. Extra credit. Staff room. Initiation. Understood?”
Fourteen voices—ten experienced, four freshly ruined—answered together.
“Understood.”
They cleaned up just enough to pass for students, helped the twins back into their uniforms (still soaked underneath), and walked out into the corridor as a single unit of fourteen free-use girls just as the under-eighteens began arriving, completely unaware.
The group chat updated before first period even started:
Twins fully initiated. Staff room destroyed. They’re perfect.
Isla already loves the half-open door risk. Freya won’t stop lactating. Maya wants it rough. Zoe asked for the cuffs again after lunch.
Three more this week. We meet them at the gates. Same line: extra credit.
Teachers are already hard again. Impatient parents too.
Year-group harvest is live.
Far away the original triad felt the four new sparks join the ten and pulsed pure satisfaction down the bond. Athena updated the living map. Dionysus raised another cup. The Fates measured the next three birthdays and smiled.
The staff room still smelled of the initiation.
The fourteen free-use girls walked to lessons dripping and coordinated.
And over the following week, three more students would turn eighteen—each one met at the gates at dawn, each one told the same sweet lie about extra credit, each one led to the staff room to learn the real responsibilities of being legal at this college.
The absolute age had turned a sixth-form into a production line of happy, railed, free-use adults.
And the line had just grown from ten to fourteen.
