Gwen + Loki
Loki had tried on five to ten different outfits - and five to ten different Lokis - before settling on the one he finally chose for this event. It wasn't because he had any strong desire to meet someone tonight, or bring someone home. Though he also wasn't against it. Rather, he thought that if the Olympians were going to through a raucous sex party, it was only right for the Asgardians (and the Queer God in particular) to show up and represent.
Admittedly, he hadn't fully considered the practical implications of wearing a floor-length coat at a sex club, but he did hope yellow chartreuse ostrich feathers were easy to clean.
Loki had decided to sign up for the event when he heard that Billy was doing it. Mostly, he'd say, because this seemed like exactly the sort of thing Tony Stark would sign up for, and he felt it was his duty as Billy's friend to keep him from getting back on that particular horse. (Not that he thought Billy was being entirely accurate with that comparison, but he wasn't going to give Tony Stark the satisfaction of knowing someone googled his dick. He probably has some sort of alert set.)
So far, he thought, he'd done an excellent job at friendship. Tony Stark wasn't here, so Billy wasn't going to go home with him. And the other Tony Stark was matched with someone else, so again, Billy wasn't going to go home with him. He was marginally less excited that Billy had now been matched up with a pink Captain America -- but you know. Baby steps.
Half-drunk on his fourth vodka cranberry, he'd almost forgotten the overarching point of the party when he saw a girl in a Smiths t-shirt and blue high tops, and started to head in her direction. She was one of the few remaining partygoers who hadn't paired off yet, and their matching eyeshadow didn't seem like pure coincidence.
"Did you have any more that you wanted to try? I can wait." He smiled, at once smug and good-natured. He lifted the key, affixed as it was to his heavy black necklace chain, and flashed it at her. "There are only a handful of us left, and I wouldn't know what to do with Emma Frost if I got her."
