A genius idea!

Considering your options, you decide to nerd by adding a fun new feature to your smartphone.

New Rule: the owner's current cellphone is upgraded, giving it an unending battery and a new, exclusive app that lets you take a photo of someone and use it to open a portal directly to their asshole. The portal also automatically lubricates anything passing through it and can be closed by turning the phone off.

You carefully pick up your phone, and there it is: a new app called Pocket-Portal-Fun. You put it on camera mode and point it at the Asian dude. He can clearly see you but doesn't seem to mind. The app then gives an information profile:

Name: Tzu-Chieh - Age: 19 - Ethnicity: Taiwanese - Body Type: Undeserved Skinniness - Sexuality: Bi - Sexual Experience: Gave head once - Mental Status: Nervous on the first date.

Fun Time! You activate the portal mode, giving you full access to his ass and balls, and start gently fingering it.

"So, hey, Tzu-Chieh, any interesting shows you've seen recently?"

"Yeah, I am really digging Dungeon Meshi right now. Samira, Ahaa!"

With him moaning almost mid-sentence, you know the portal is actually working, but you will need to make sure he doesn't run away from this date.

New Rule: People named Tzu-Chieh can't flee from dates in coffee shops, including going to the bathroom without actually needing to.

"Are you okay? You just hopped suddenly."

"No, I'm okay; I just think the world-building is amazingggg! And it's really worth getting into even if you don't normally like animeeee!"

"You are cute; you know that, right? But tell me, what's the plot about?"

Time to ramp up the challenge. You think he is ready to take something bigger, but this time you will take a less hands-on approach.

New Rule: The owner of The Rule book has a thick 7.5-inch cock with virtually zero refractory period. And proportionally sized balls.
