Preparation for the Unthinkable

Tsukasa's fingers danced across Nene's skin, spreading the clear liquid in a gentle, yet deliberate motion. He was oiling her up, making sure she was slick and ready for what was to come. The liquid dripped down the crack of her ass, pooling at the base of her spine as he worked it into her skin. Nene felt a shiver run down her spine as she realized just how thorough Tsukasa was being. Her upper back was soon covered in a thin layer of oil, but it was her cheeks that were the main focus. Tsukasa's hands grasped her cheeks, pulling them apart as he continued to drizzle the liquid over her skin. Nene felt a wave of embarrassment wash over her as she realized just how exposed she was. Her cheeks were now covered in a glossy layer of oil, the liquid glistening in the dim light of the room. Amane's hands still grasped her waist, holding her in place as Tsukasa continued his ministrations. Nene felt a sense of anticipation building inside her, mixed with a growing sense of unease. What was about to happen, and was she really ready for it? Tsukasa's hands raised her ass even higher, his fingers parting her cheeks as he prepared for the next step. Nene felt a surge of fear mixed with excitement as she realized what was about to happen. Tsukasa's hand moved, the bottle of lube once again coming into contact with her skin. This time, however, Tsukasa was more direct. He squeezed the bottle, a stream of liquid shooting out and directly into her ass. Nene let out a startled gasp as the liquid rushed inside her, filling her up. She felt a sensation of fullness, mixed with a growing sense of discomfort. Tsukasa's hands didn't let up, continuing to massage the liquid into her skin. Nene felt herself relaxing, just a little, as the sensation of fullness began to recede. She was still aware of the liquid inside her, but it was no longer uncomfortable. As Tsukasa finished, Amane leaned forward, his chest pressing against her back once more. "You're doing great, Nene," he whispered, his breath caressing her ear. "We're almost ready to begin." Nene felt a shiver run down her spine as she realized just how close she was to the unknown. What was about to happen, and would she be able to handle it? Only time would tell.
