Go to the bathroom and see what Evan gave you.

You shut the bathroom door and lean on it, catching your breath. Your heart is beating a mile a minute. Just an hour ago you were a straight man, only dreaming of ever straying. Now you've kissed a man, and touched his dick. Soon you'd be dressing up for him, and god knows what else.

You hear the men laughing from the room behind you, and their beers clinking together. You look at yourself in the mirror, your share disheveled, looking every bit the slut you felt like. You turn your gaze to the bag, and pull from it a small piece of black lace. Evan wanted you to wear that?

In your hands is a tiny black thong, the lacy cotton soft to the touch. You take a deep breath, slowly removing your clothes. Slipping out of your tight white briefs, you see your hard cock in the mirror. Until tonight, you thought it was big. Your wife had always told you so. After you felt Evan's, you can't be so sure. And soon Chris and Josh's dicks too. You think, your mouth watering.

You pull the thong up your legs, and feel the string at the back riding up your crack. You're glad you shaved and waxed for the weekend, and feel like a total slut with your ass on show. The cotton stretches thin on your cock, which threatens to burst out at any moment. You grab your champagne, downing it in one gulp and turning to the mirror.

A slut stares back at you, a tight, muscular body stretching against a black lacy thong, which rides up your perky ass. You wonder if your wife ever looked so good in a thong, and can't remember a time she did. The nerves are still bubbling inside you, but the champagne and horniness work together to quell them, and you turn to the bathroom door.
