Serving at the Party

DIIIING The doorbell rings, announcing the arrival of the first guests. Remembering Natalie's words, you open the door to greet them. It is a stern-looking woman in a salmon blouse and pencil skirt.
"Welcome to our home." You say, "The ladies are in the living room, through there. May I take your coat?" The woman says nothing; she briefly glances at you, taking in your attire and your caged cock, shoves her coat into your arms and continues wordlessly into the main room.

You hope that that first interaction of the night is not an omen of what's to come, and it's not. Most of the guests are cheerful and pleasant, most of them are also dressed for partying, in low-cut dresses or tight pants. Your dick is already painfully tight against the confines of the chastity cage. You figure it'll be like that for the whole night, so you better get used to the pain.
Not that you have much time to pay attention to the pain. You're run off your feet all night. Serving wine, shots of tequila, and just generally attending to the guests. Not all of them are as aloof as the first woman. Some of the guests are intrigued by your situation, others are amused and giggly, and a few of them openly mock you and start teasing you to get you hard and watch you wince.
"How did you end up with a locked little servant like that?" One of the guests asked Joy.
"Oh, he moved in with us, and we convinced him that it would be best for everyone for us to lock away his cock." Joy replied.
"Hmm, I wonder if I could do the same thing with my obnoxious roommate." The guest mused.

As the party went on, and the guests got more and more drunk, they became more and more brazen about teasing you.
"Little locked bitch-boy." A pretty blonde girl teased. "I bet you secretly love this, don't you? You're a little perv and that's why the girls had to lock you away. What did they tell you to do tonight?"
"They told me to serve the guests, and just generally be there if they needed anything." You reply stiffly, trying not to engage in the conversation any further.
"Anything." The blonde girl said, "Hmmm, I like the sound of that. It turns out there's something I really need, something that would be perfect for a little locked perv like you. As you can see, I wore this skin-tight leather top. It's very fashionable and it makes me look sexy, but I've been dancing and I've really worked up a sweat. It's really hot now and I'm sweating like a pig in here. I'm going to take my top off for a while and just wear my bra, in the meantime I need you to lick up all the sweat from the inside of my top...make it nice and clean." With that she took off her wet leather top, shoved it into your arms and sashayed off to dance at the next song. Standing there, holding her top, you can feel that it is indeed sweaty, it's actually dripping. You spot Natalie nearby and she meets your eye. She gives a slight nod and fingers the key around her neck, reminding you of what's at stake. At this point your cock is really hurting, which only strengthens your resolve to finally get a release. Keeping eye contact, you bring the sweaty leather top to your mouth and give it a big lick, wrinkling your nose slightly at the saltiness of the sweat. You go in for a second lick and Natalie turns back to her conversation.

The girl returned about half an hour later, out of breath and quite pleased with the work you'd done. "I bet you loved it, you little perv." She was far from the only guest with strange requests though. Once the guests realized that you had to cater to their whims, they asked more and more. Three girls used you as a footstool while they sat and talked for nearly an hour, which was **** on your knees. One guest wanted you to take a video of her making out with her girlfriend. She made you reshoot it five times. You could see from the smirk on her face that she was just enjoying teasing you, making you aroused knowing you could never get hard. You complied with all their requests though, smiling through it all. You weren't going to blow your chance at a release.

The party finished sometime in the early hours of the morning. You weren't exactly sure when. The girls left you to clean up and went to bed. By the time you finally got off to bed yourself, the sky was just starting to lighten with the first rays of dawn.
