A little Exhibition seems appropriate

You take her clothes, almost everything but her panties and jacket. You let her wear her panties this time, with the condition that she needs to keep your cum in her and not try to clean it up. Then you have her wear the jacket. You let her know that you and her will be having a nice trip, and she won't be needing all the extra layers for your trip. Pokimane is a bit confused, as the jacket barely covered much, it kept a good gap down her chest, giving a nice view of her cleavage and letting everyone know nothing else is under, and only barely goes below her panties, meaning even the slightest movement can ride it up and expose her. You could tell she was a tad bit panicked but there was a slight hint of excitement in her too. You could see her hidden desires and you were going to exploit every last bit of it, turn her into the perfect slut for yourself. You take her out of the stall, making sure to flaunt her body as you exit the bathrooms and back to the Starbucks and then out.

You decide the best way to travel would be through the bus, so you let her put her glasses and cap back on, both hiding her identity and completing the perverted flasher look for her. You get on the bus with her, sitting on a three person seats. With her in the middle. She's already soaked and also leaking your cum as is, but you decide to spice it up, using your phone, you click on her, adding in the instructions " Being touched by me turns you on immensely, Being shown off by me turns you on a lot" As you finish typing that, another man comes in, tries to take a different seat, before stopping, presumably getting a good look at Pokimane, before taking the seat next to her. He probably didn't recognize her, but took the chance to get a better view of what seemed to be a partially naked slut just sitting there.
