She asks for permission first

As Penny stared at the book lying dormant on the kitchen's table, everything around her seemed to cease existing. All of her sexual fantasies, just a few strokes of a pen away. The scenarios, the scenes unfolding in her brain. Her legs fidgeted together as arousal slowly built inside her, biting her lips even more.

A sigh from someone nearby broke her from her reverie, coming back down to Earth and looking at a very exhausted Lydia nearby. She swiftly realized where she was once more, the skin around her freckles taking on a soft shade of red. The owner of this incredible artifact currently had her eyes closed, fighting to stay conscious.

Penny looked back to the book once more. She could just snatch it and make a run for it, if she really wanted to. Lydia was in absolutely no shape to pursue her. But not only would this go against her convictions, her hairstyle kind of make her stick out like a sore thumb. Plus, Lydia also knew her name. Yet, she absolutely couldn't let this one-in-a-lifetime chance just go past her.

"Ehm... L-lydia?" she quietly asked. The other girl mumbled an affirmative. "Would it be okay... If I were to... You know..." With each word, her speech grew more unintelligible.

"Wanna use the book?" Lydia said it so nonchalantly it surprised the blue haired girl, straightening her posture. "Can you do something for me first?" she quietly asked.

"S-sure! Anything!"

"Please carry me back to my bed, I can barely hold on right now."

Penny gently lifted her off the ground once more, going back towards the bedroom. She placed the exhausted girl on the least soiled part of the mattress and tucked her in as well.

"Thank you," Lydia mumbled. "Yeah, you can use it. Just leave me out of everything, and leave the book on the table once you're done with it." And with that final sentence, she fell in a deep slumber, way too exhausted to even care about the stranger left unattended in her dorm, finally able to rest after this whole ordeal.

Penny's heartbeat began to skyrocket. Nothing was holding her back but herself, now. She grabbed the nearby discarded pen as she shuffled her way back to the kitchen, the fantasies invading her thoughts once more. She just had to formulate her wishes down carefully to not fall in the same helpless trap as the girl she just rescued.
