This is the final chapter of this series.

The darkness descended and the bookshelf swung shut to seal them into the bedroom. They were already on one another in an instant. Quinn felt hands on her goosebumped skin, unsure who it was. She didn't care anymore. None of them did. One moment she felt Meena's glasses pressed against her breasts, and just as she had some bearing on who was doing what, someone else tugged her away by her ponytail, and suddenly she was on all fours with a mouth to her clit. The fun was short-lived, each of them reaching a quick climax as the temperature dropped to a point where they all had to get hurriedly under the covers.
They snuggled together for warmth, and Will quickly surmised he was in the familiar position of being nestled between Quinn and Ellen, hearing Meena whisper something from behind Ellen. Ellen moved away a little and he heard the two girls snogging, leaving him with Quinn. Her naked figure hugged closely into his, her slim fingers trailing his chest. He leaned in for a kiss, and she reciprocated, the room now nearly silent, punctuated with the occasional moan. Manoeuvring carefully in the dark, she brought her leg over his waist to straddle him, continuing their slow kisses, grinding her body against his. She felt him harden, the thickness pressing against her clit as she rubbed against it. Their kisses became breathy, and Quinn was overcome with the gnawing anticipation. She rose up, fumbling for his cock and pressing his hard tip to her entrance, moving downward and savouring the feeling of his shaft pushing deeper into her. It reminded her of her first time on the beach, failing to master the motions required to fuck from on-top, but now finding the rolling of her hips came naturally, grinding her clit to his pelvis with each meticulous thrust.
She moaned, tipsy and horny, reaching up to claw her nails into his shoulder. Quinn hoped he would be able to cum, she longed to feel him fill her up and leak out of her like he had just done with Meena in the kitchen. His hands were on her ass, his mouth finding one of her nipples, and she surprised herself by squirting around his dick with a shriek. Forcing herself to keep going, she tuned her ear to the squelching from the girls beside them, their fingers drunkenly attempting to stay fixed on one-another's g-spots. It was sexy hearing them play so close by. She heard Meena cry out in climax, then again soon after, Ellen clearly more adept. There was some shuffling as Meena gave up on this approach, readjusting her position and instead strumming her friend's clit against the bumps of her fingers, with quick wrist movements which quickly had Ellen squealing, until the two of them fell to their backs, gasping for air.
Meena was dumbfounded by Ellen's ability with her fingers. It was undoubtedly the quickest she had ever been brought to orgasm. Being with a girl was still new and unfamiliar, but Meena found herself becoming increasingly intrigued by it. Especially now as she felt Ellen snaking down her body and trailing small bites down her hips as she went, until her friend's tongue found her clit and began lapping at it, first softly and then more firm, her fingers pumping in and out. Meena was soaked, her juices coating Ellen's fingers, and Meena wondered if some of it was the remnants of Will's cum from earlier, the thought brought her immediately rising up towards orgasm, Ellen continued her treatment, Meena thrashing and screaming as the orgasm split her body into brilliant shards, and another equally monumental climax followed behind it and made her whole again. The gutteral sounds she heard herself making shocked Meera, and Ellen took this as her cue to let up, climbing up from the depths of the damp duvet to join Meena in a sticky embrace.
The cuddling was unexpected, but nice. Meena found herself smiling, and felt Ellen would be too, with that familiar conniving grin. The same one Ellen had been sporting when she had first approached Meena in the teacher's lounge. Even then, friendly and innocuous as it had seemed, looking back it should have been clear she was flirting, and Meena wondered if their entire friendship had been sparked by Ellen's attraction to her. That was quite sweet in a way, and Meena squeezed her friend into her, relishing the warmth as she listened in on Quinn and Will's continued escapades. She was screeching with every orgasm, and it was clear the drinking had made her louder, only growing more salacious as she started talking.
"Fuck you feel so good inside me Will," she moaned into his ear, "you're making me cum so hard, I can't stop cumming around you!" She screamed, squirting around him a third time. The tight pulsing around his shaft finished him off too, his balls tightening as he shot her full of the little spunk he had left. He gripped her soft hips, guiding her final slowed thrusts until he had emptied into her, and for a moment she paused there, relishing the sensation of him seeping out of her tight spent hole.
She gently lifted off him, hands to his chest to steady herself, lying softly beside him and turning over so he could spoon her. Quinn found herself immersed in the flowery scent of Ellen's perfume, feeling the tendrils of some of her soft curls against her face, and moved closer to spoon Ellen from behind. Will shuffled over to do the same behind Quinn, and just like that they were all nestled together, slowly drifting off as the fourth key was unknowingly awarded to them, somewhere in the darkness.

Quinn woke first to the unwelcome artificial brightness of the apartment's alarm system. She was still giddy from the lust of the night before, but equally curious to find out if they would be allowed to leave today. The key on the wall caught her eye, and she sat up, snatching it from it's hook inside the wall-panel, and unintentionally pushed Will awake in the process. As the key was taken, the bookcase doors began to roll open, and the sudden gust of renewed air was enough to rouse Meena and Ellen too.
"Fucking hell, why is it so bright?" Ellen mumbled, shielding her eyes with one hand as she rubbed at the bridge of her nose with the other. "Anyone else feeling woozy?" she asked, met with silent tired nods.
They clambered out of the bed at the sight of platters of fruit and pastries - an extra treat this time - their stomachs growling. Quinn brought the key with her, and after tucking into a pan au chocolat, slotted their reward into the fourth keyhole and turned it. The bathrooms unlocked with a click. She would be glad of a shower, knowing she wasn't the only one feeling sticky and in need of freshening up. The bathroom doors had changed. There were a pair of their avatars on each door, framed in coloured circular signs. Quinn and Will were together on one, the two girls on the other. She called to the rest to come look, and they wandered over, Will bringing over a cluster of red grapes for Quinn, who took it with a smile.
"Hmm. One last challenge I suppose." Said Meena, readjusting her glasses and looking from the door to Quinn, "What time do you suppose it is?"
"Feels like early morning to me." she replied, stifling a yawn, "If we can get that fifth key and be out of here, maybe we'll get our stuff back and we can make our afternoon flight." Quinn sounded hopeful, and the group mirrored her enthusiasm, Will reaching forward and turning the handle to their assigned bathroom as Meena and Ellen left towards theirs.
Ellen looked back before descending inside, "Good luck." she said knowingly, addressed seemingly to Quinn. There was a mutual understanding in their exchanged looks: of all the fetishes they had been forced to expose on their first night, everyone had been made to act them out: Ellen as the dominatrix; Will's fixation with feet; and Meena's fetish for cum. Yet despite Quinn being made to admit her yearning to try anal sex, she hadn't yet been made to do it. Surely this would be the nature of this next challenge. It simultaneously excited and terrified her.
Will was standing patiently in the doorway to the bathroom, and reached out to take her dainty hand in his, a calming presence guiding her inside. He brought her over to the sink with a hand to the small of her back, and she smiled at how he was being so protective of her. He prepared the two toothbrushes they had been provided, handing it to her and starting to brush together, their eyes locked on one another.
