No, she needs to put anal experimentation behind her.

[Note: This chapter is a little more scene-setting, so I published the next one at the same time if that's not your speed]

"No. I can't do that. I made a mistake. Thank you so much for helping me, but this is the end of... this kind of thing for me."

I'm meant to be filled. My ass craves penetration and ****.

That voice in her head, that manifestation of shameful lusts and impulses was quieter now though, submerged by her resolve.

"Oh," Steve said, failing to hide his surprise, "Well... That's good. Hey, uh, are you still studying with my program for the test?"

"Uh, weird change of subject but yeah. I think it's working real well too!"

"Good. I have a new set of lessons I programmed in," he walked to the kitchen to wash lube off his hands, glowering, then went to his room for a few minutes before emerging with a small bag. "Here's the new one, and some other stuff for you. Open it at home."

"Sure, that's sweet of you Steve. You're great."

Cassie smiled at Steve, she'd been right to trust him. _Steve is helpful, Steve is trustworthy, listen to Steve. _He smiled back, though it looked more like a grimace to her. What could be bothering him? That she'd rejected his suggestion? Well, she'd made up her mind about it for the best. He'd be happy enough that he'd helped her. And gotten a feel of her ass too.

God, she hoped he didn't think that would happen again, no matter how much she liked him as a friend!

She felt at ease for the first time in a couple of days as she walked back. In her dorm she threw Steve's package on the bed and forgot about it until later that night, when it was time to study. She opened up the bag, expecting just another flash drive like the first he'd given her, but inside there was also a note, and a 4-inch black object. She stared at it, puzzled, then read the note.

In case you change your mind, it'll be safer with this.

- Steve

She looked at the object again. A butt plug! she realized. Well, that was thoughtful of him but she wouldn't be needing it. She took out the flash drive, plugged it into her laptop and threw the rest of the bag in the corner.
