The group passes your dick around

Amy, the redhead, gets the first go. You breathe heavily as you watch her gingerly take your cock from Erica, feeling her cold hands cup your balls and circle around your shaft. She casts a brief glance to you, and watches your reaction as she sloppily licks your dick to get it lubed up before slowly pushing the head into her throat. The warmth and wetness of her mouth drives you insane and you thrash against your cuffs, groaning "Fuuuccckk..." huskily. The girls are split between watching you writhe and seeing how far Amy can take your cock. She's skilled, which is good for her and bad for you as you feel her throat constrict around the tip of your cock. She holds it there for a couple of seconds until she gags and slowly pulls it back out. As soon as it hits the cool air, you cut off your moan and fall forward, held up by the cuffs. This was going to be a long night.

Kelly is the next to go. She doesn't get nearly as far as Amy, but gives it multiple tries, swirling her tongue around your head to get you even more aroused. She passes it to a girl whose name you don't know and the game continues. Over the course of 30 minutes or so, your cock gets handed from girl to girl. Eventually, the game and drinks take their attention away from your hoarse moaning and they return to laughing and talking with each other, egging on whoever currently has the "dildo". You try to beg for release, but are mostly ignored. You really have become Erica's personal toy. She must have done something to keep the sensation going; despite the constant stimulation, you haven't gone numb yet. Instead, each mouth feels like a fresh tortuous pleasure.

Eventually, Amy is declared the winner, despite everyone's best efforts. The group cheers drunkenly for her. "What do I win?" She asks. Almost expectantly, the girls turn to Erica, who takes a big swig of her drink before replying "Whatever you want!" She turns her gaze from Amy to you. "As long as you give her back, you can do whatever you want to our little party slut here."
