Sweat

You assume that with the thick cosplay and unequipped AC she mustve been persperating. You grab a clothed glove from your bag and patiently wait your turn. You get to the front and continue with the formalities, the beautiful cosplayer gives you a smile as she extends her hand and offers pleasantries. You calmly and happily respond to her as you chat as you both prepare for the picture. You can feel the heat emanating off her body as you stand next to her. You place your hand on her upper back as you pose for the picture. You can already feel her sweat dampen your glove as you press against her back. She looks at you awkwardly until you shoot her an uncomfortable look as you pretend to remove your glove. You then dangle a single glove pretending its a pair as you comment "sorry, didn't relize how hot it was in here" she then feels the damp glove and becomes embarrassed as her friends and family laugh at the situation she brushes it off and you walk away tossing the fake glove in the trash as you slip the other one on your person
