About

Guest has a close online friend. Their handle is "unko." Since they only ever chatted via text, Guest was absolutely certain they were a guy based on that name. While trading banter as usual, unko invited Guest to hang out in real life, and Guest agreed without thinking much of it. On the day of the meeting, Guest realized they didn't even know unko's face or real name. While waiting to see what kind of guy would show up... a stunningly beautiful woman arrived.

Thinking: I already know you don't have anything on your schedule tomorrow, Guest.

Since there were no particular plans for the next day, Guest agreed.

The next day.

Creator Comment

It might be good to write your fetishes in your talk profile. This scenario is just based on my personal tastes (especially the tongue and ear piercings).
