It had been a few weeks since Bree and Paige first used their strap on together. Since then, they had been fucking with it on a nightly basis. The sex was getting better with each passing day. The sisters were enjoying their secret trysts so much, they found themselves looking forward to curfew falling, so they could climb in bed and screw each other like animals in heat.
By now they'd explored every position imaginable with each other several times over. It had become normal practice for the girls to walk into the room and immediately strip naked, pulling each other to the nearest mattress and taking turns fucking one another until the early hours of the next morning.
Bree had just finished her last class of the day and was walking back to her dorm to drop her books before having dinner in the cafeteria. She spotted Paige worming through the crowded hall towards her and a wide grin spread across her face.
"Hey, you." she said cheerfully as her sister approached.
"Hey! Heading to the dorm?" Paige asked, wearing just as big a grin.
"Yup."
"Cool, I'll walk with you."
The sisters walked side by side, and laced their fingers together, locking hands. To the casual observer, this would seem relatively innocent, but the sisters enjoyed the intimate contact, reminded of the naughty secret they shared.
"So... who gets to wear Melvin first tonight?" Paige asked with a mischievous smirk.
"Hmm... I think you were the last one to use him this morning, but honestly, it's all a bit hazy." Bree replied with a laugh. "We went for fucking hours last night! We'll just flip a coin or something."
As they rounded the corner into their dorm block, their smiles faded, and their eyes filled suddenly with dread.
"Shit!" Bree muttered. "They're doing a fucking raid!"
Every door in their corridor was currently propped open, and guards with clipboards and rubber gloves were moving from room to room. The students who had been in their dorms were made to stand outside their doors and wait quietly as the authorities conducted random searches.
The sisters made their way anxiously to their room, their hearts pounding in their chests.
"Contraband found! Unit 573!" bellowed one of the guards suddenly, stepping out into the hall.
"Fuck!" Bree and Paige swore simultaneously. Unit 573 was there's. The guard spotted them, and a cruel smirk curled on his greasy lips. "Unit 573." he repeated, locking eyes with the sisters. "One sex toy found."
He lifted Melvin in his hand and dropped him into a garbage bag, held open by another guard. Flipping his notebook open, he sauntered towards the girls, and scribbled something on the waxy page.
"Punishment is ten demerit points, and an hour taken off your curfew, ladies." He tore the page off and handed it to Breanna. "Keep your noses clean, now. We wouldn't want to have to haul you down to the high security wing."
Bree snatched the paper from him without a word and he chuckled, winking at her before moving on to the next dorm.
"Come on. Let's get out of here." Paige said, taking Bree by the arm and leading her out of the dorm block.
-------------------------------------------------------------------
That night, the sisters were sullen as they got ready for bed in silence.
"I suppose I should just sleep in my own bed tonight..." Paige finally said. She realized she hadn't done so since Bree had first gotten the strap on.
"I can't see why you wouldn't... We can't do much without Melvin here, can we." Bree replied sombrely. She pulled her dresser open and took out a shirt to sleep in. She hadn't used it, or any other sleepwear for that matter, in weeks.
"Do you think we can get another one from Bonnie?" Paige asked, her voice hopeful.
Bree shook her head and sat on her mattress. "They'll be watching us now... Probably do random checks every other day for the next month." she sighed. "If we get caught again, we'll get shipped to the H.S.W. for sure."
"Yeah..." Paige replied, sinking into her own pillow glumly. "Good night, Sis."
"G'night."
An hour later, Bree was still wide awake, tossing and turning on her pillow in frustration. Her body ached with a powerful need for sex. She'd grown so accustomed to cumming before falling asleep. Try as she might, she couldn't seem to quell the need in her yearning pussy.
She looked over to her sister's bed and whispered: "Hey, Paige! You awake?"
Paige rolled over and let out a heavy sigh. "Yup. Can't sleep."
"Me neither."
The sisters lay in silence, then Bree continued. "You want to come over?"
Paige hesitated, then flipped off her blankets and got up, padding over to her sister's bed. Bree held open her covers and Paige climbed in next to her. They lay together quietly for several minutes.
"I'm so fucking horny." Paige finally sighed.
"Me too."
The sisters looked at each other, and Paige bit her lip. "I was thinking..." she said tentatively. "What if we tried it... without Melvin."
Bree's eyes widened and she fidgeted nervously. "What do you mean, exactly?"
"Well... like... if we just tried fucking... just, like... without the cock between us."
Bree seemed very hesitant. "You mean, just... bumping our mounds? How is that gonna make us cum?" she asked.
"I dunno... I heard that some girls around here do it... Figured it was worth a try?"
The girls fell silent again. Bree thought about what her sister was suggesting. It sounded a bit... lesbian to her. I mean, using Melvin was one thing... that was fucking a cock. She had gotten comfortable with that. Part of her worried rubbing pussies was getting a bit too dykish, but she was desperate for a good cum, and decided she was willing to try just about anything.
"Ok, let's do it." she said.
Paige's eyes brightened and she sat up, pulling her shirt hastily over her head. Seeing her sister strip got Bree excited too and she hurried to get naked as well. The girls pulled their panties off and tossed them to the floor. They pushed the blankets out of the way, and Paige rolled on top of the older girl, positioning herself between her open thighs.
