The back of the library

Riley pulled Lilian through the halls at a pace fast enough that Lilian avoided receiving additional spanks. Eventually she led her through an unassuming door into what Lilian suspected was the schools library.

There were rows of books to be sure, but she couldn't see any sign of categorisation nor any librarian to check out any books. The lights at the front flickered inconsistently and at the back had faded to a point where any reading would have strained the eyes. Lilian imagined prison library's would be better presented than this but what else could this room be?

"This is the library?" Lilian asked

"Yeah, I heard a couple years back the librarian was caught sleeping with a bunch if students" Riley replied nonchalantly "So they had to fire her and just, kinda didn't hire anyone else?"

"They fired her for that?" Lilian questioned, napping on the job with student didn't seem like it needed such a harsh punishment to her.

"Yeah I know right! I mean what's the point of having a hot milf librarian around otherwise, it's not like anybody came here to read!"

Riley navigated them through the rows of books which were arranged like a maze until they arrived at a dead end. The secluded spot was dimly lit and surrounded by densely filled shelves on three sides. Ryan was sitting on on of the two beanbags which were tucked into the corner and gave the girls a small wave.

"You remember Lilian right bro?" Riley asked her brother. "I invited her here to she could tell us how the hell she ended up like this."

Ryan's gaze flickered between Lilian and his sister as he adjusted his position to try and hide the effect her new outfit was having on him.

"Uhhh hey again Lilian." He spoke softly, a stark contrast to Riley's expressive style of speech.

"I thought were were.... you know...." he addressed his sister.

"Oh don't worry about that, I just thought you'd like a little show and tell to go with it."

Riley smirked and then pounced on top of her brother, facing him on his lap while her hands rested against the shelf just above his head. She glanced back at Lilian, making sure the girl was watching and then brought her lips to Ryan's.

There embrace was deep and passionate, nothing like the peck she would give her father or brother. It was the kind if kiss she had only seen once in her life, after her parent had a little to drink and didn't realise she could see them.

Ryan's hands gripped into his sisters thighs as she kissed him more aggressively. They began to moan softly and Lilian to her surprise did too. With a mind of its own her hand had began caressing her pussy as she watched their passionate display.

Riley finally broke the kiss, he tongue leaving her brothers mouth with a string of saliva briefly forming between them. She got off her brother, sinking into the empty beanbag and beckoned him over. Ryan shuffles over to sit in her lap facing Lilian, his sister kissing down his neck as he adjusted his position.

"Alright then Lilian, tell us how your days been" Riley asked her, one hand holding him tight against the chest while her other hand crept into his pants.

Lilian was at a loss for words seeing the pair. All her life she assumed she was quite close to her brother, but level of affecting between these two was far more than she'd ever done at home. did Damian want this level of intimacy with her? Was it something Lilian was meant to initiate?

"Well errr, there were these guys in class." She began explaining

"Oooohhh do tell" Riley purred as he hands caressed her brother.

"I forgot my bag in the rush this morning so I needed to borrow some stuff."

"Right"

"So I asked these guys next to me and they were happy to lend me stuff but they needed to trust me first."

"Of course, can't just give your thing away to a stranger." Riley commented

She was alternating between looking at Lilian and licking the length of Ryan's neck. Ryan himself seemed content with his position, intently staring at Lilian as she talked.

"So we agreed that I would hand over my panties as like, collateral. I didn't really have anything else on me, so i had to bend over and give them up." Lilian felt a little awkward just standing in front of them, but they both did seem engrossed in her story.

"Show us how you did it" Riley commanded her as she expertly unzipped Ryan's pants and reached in to expose his cock.

"Well I was about this close." Lilian move closer, getting a clearer view of Ryan's cock. It was a lot like Tim's, slender but long, although it's tip was more like what she expected and it was far cleaner than Tim's.

She watched as Riley moved her hand up and down the length of his shaft, in slow deliberate motions. After taking in that sight, she turned around bent over and slowly lowered her string of panties down her legs.

She felt Ryan's hands grab onto her ass and pull them, opening and exposing her pussy. She held her position for a moment before turning back around and handing her panties over to him.

"So then I handed them over and started my work." She continued, eyes locked onto Ryan's cock as Riley slowly increased her pace.

"And after, well, they had cut them down to that size."

"And you just put them on?" Ryan asked, his voice slightly strained as his sister seductively nibbled his ears.

"Well I was a little mad, but they only wanted to make my clothes more trendy." Lilian could feel that energy take over her again, it was biting at her with a greater intensity after having come so close to a relief last time.

"They were being so nice, telling me I looked good, taking my picture, having me pose." The memory of the even pushed Lilian's hand back to her glistening pussy as she spoke.

"Fuck me I wanna see those" Riley cooed, moving her hand under her brothers shirt to tease his nipples. "But what about the rest of your clothes?"

"Well after that I wanted to find you, but I didn't know where to look." Lilian explained, her breaths getting tighter. "So I went to the art room and, well... there were more boys..."

"Mmmmm you greedy girl, leave some for the rest of us" Riley joked

"There, there was a crash... and then I needed to pose naked for them..." Lilian was having trouble putting her thoughts together, the tension and heat was building so much faster this time as she buried two of her own fingers into her wet hole.

"Keep going!" Riley was pumping her hand up and down fast now as Ryan rolled his head back and started to clench his fingers.

"I... hahhh.... I ended up with one of there cocks in my mouth with the other ran his tongue into me!" She was crying out the words as she to increased the pace of her fingers.

"God,Fuck, NOW!" Ryan screamed out and immediately his sister threw her head down, swallowing up the tip of his cock. Ryan's moans of pleasure were enough to push Lilian over the top.

"HhhahaaaaaaAAAhhhhh" She squealed, dropping to her knees as her body convulsed through the waves of pleasure she was receiving.

She fell forward, her body resting against the twins as she breathed deep to recover herself. Then she felt Riley's lips embrace her own, their tongues intertwining as Riley explored her mouth. With her tongue came that same thick and warm substance she had tasted before.

Riley broke the kiss, smiling at her as she brought a hand to her chin.

"Open up and let him see before you swallow." She commanded

Lilian, still basking in the afterglow, opened her mouth without question. Making sure Ryan got a nice look before swallowing it all, running her tongue over her lips to clean it.

They lay in a pile together, relaxing in each other's embrace. Lilian felt at peace with them, like she had found a place in the outside world where she belonged.

She didn't want to interrupt this moment but she had so many questions about what she was experiencing. But what of her lack of understanding pushed them away? Could she risk that chance?
