Nope, he gets a good chunk of them out of the way!

As Issei reached the park, having dropped the box off at his place, and put about a third of the sheets into his bag, rather than haul around the whole damn box. He wasn't stupid enough to think he would offload all of them in one go anyway, so working with thirds? Much more manageable. He then called up Rias. "So... can I wish to have a sense for who might have issues with their love life we could easily solve with either Devil Powers or your magic?" he asked her over the phone in an undertone.

"Naturally, Master, would you like to wish for that?" Rias asked from the other end of the line, and Issei paused, considering as a thought occured to him.

"...just so we're clear, do I have any right to refuse any contracts should anyone actually use these sheets?" Issei then asked. "Assuming I don't like what they're asking for of course?"

"You do, though it's not recommended to do so willy nilly, it looks bad on any reports," Rias answered for him. "Why do you ask?"

"...just in case the client is the kind of jerk off that would make someone else fall in love with them or otherwise have sex with them against their will," Issei explained. "I am a pervert, proud of it in fact, but I will NOT be an accomplice to ****," Issei said firmly.

"Ah, okay, that makes sense, Master," Rias nodded, though he couldn't see her do so over the phone. "You can always wish to have a sense for anyone who would have a relatively benign wish to aid in their sex life to avoid the need for cancelling contracts. It's good that you're using everything you have available to you in order to do your work as a Devil, but won't cross any lines with my power. I'll be sure to let the Peerage know you're being responsible."

"Thanks," he blushed, a little unused to praise. "Okay, I wish for what you just suggested." He heard the sound of fingers being snapped on the other end.

"Done, Master, good luck!"

Issei nodded and hung up, before walking into the park, passing out the papers to anyone who he thought might take one.

...

Several hours, what felt like interacting with hundreds of people, and a few other locations later, Issei finally returned to his place. "Whew! That's about a third of them down!" he panted. He greeted his parents, got a quick bite of dinner, and headed back upstairs. Despite half expecting to see it already, he stopped when he saw Rias on his bed in her harem outfit.

She grinned at Issei behind her veil, and purred, "Hello, Master. I hope you're ready to have some fun with me..." As she spoke, she laid on her side, running a hand along the outside of her thigh.
