Underground sex -kennel

Upon waking up, you're in a small, plain room, which feels more or less like a cell.

There are no bars, but the door seems to be made of steel and fastened with an electronic lock. You're entirely naked, aside from a collar, and a plain metal chastity device fitted onto your genitals.

Escape seems impossible, but after a few minutes, you try calling out for some help.

Nothing happens immediately, but after a few minutes, a tall black woman dressed in a professional-looking security uniform enters your room with a scowl on her face.

"Shut up!" Pulling out a taser, she seems to take a large amount of enjoyment in threatening you with it before departing the room; thankfully without tazing you.

Every so often, food is brought in by a bored-looking maid, and there's a toilet over to one side of the room, so your needs are met, but the boredom is overwhelming; you can't even jack off to pass the time.

For what feels like an eternity, but is probably only a few days, the security-woman returns, flanked by a short similiarly dressed woman with blonde hair.

"Good news #13, you've got a customer!" She grins sadistically at your confusion, and the two guards escort you to another room, a bathroom this time.

The two of them grope you shamelessly while cleaning you with soap and water, then carefully even shave your face, removing several days' worth of stubble.

Your chastity cage is removed, and the blonde guard forces you to swallow several pills of unknown origin.

You feel a raging torrent of lust building inside you soon after, and the black woman eyes your stiffening erection for several seconds before nodding.

"Looks like the aphrodisiacs are doing the trick. Let's bring him in."

The blonde woman begins talking while the pair of them pull you to yet another room.
She sounds bored, as if giving a prepared speech that she's said dozens of times before.

"In a few moments, you're going to be dealing with a customer. She's paid a lot of money for this, so make sure she goes away satisfied alright? Do what she says or you'll be punished later. If you do a good job, you'll get some extra luxuries. Clothes, books, maybe a video game console. The Madame even lets the obedient slaves spend some time socializing in the common area."

The thought of anything to reduce the numbing boredom interests you, but before you can ask anything more, you're pushed into a room. The furnishings look like something out of a five-star hotel, right down to the large bed in the middle of the room.

Atop the bed is a naked woman, maybe twenty years older than you, with a plain face and average figure. When you open your mouth to speak, she cuts you off bossily.

"You're not being paid to talk! Come here and please me, boy!"

She's not particularly attractive to your sensibilities, but the pills the guard gave you earlier seem extremely potent, because when the woman spreads her legs and orders you, you don't feel the slightest ****.

Head filled with the thought of thrusting your dick inside her, you barely even register her cries of "yes! That hungry gaze" and "ravish me!"

You forget about your objective of 'pleasing her', but over the course of cumming inside the woman a full four times before being too drained to go on, you seem to have made her orgasm multiple times, and her gaze is uncomfortably heated when she looks at you as she finally departs the room.

The two guards escort you back to the washroom, cleaning you again, then bringing you back to your room after locking your dick back up.

A few hours later, the blonde guard opens the door. "Good job #13. Your customer said she'll be back to rent you again, so here's your reward." Sounding bored, she tosses in a set of plain-looking clothes and a few paperback novels, then slams the door.

Weeks pass, and to the outside world, you just seem to vanish.

You get more 'customers' over time, most of them seeming to be wealthy housewives or businesswomen who aren't getting laid often or well-enough on their outside lives.

They're rarely above 'average' in appearance, and most of your encounters involve the guards drugging you up with aphrodisiacs, but you still find yourself looking forwards to your sole source of sexual release.

Your quality of life does improve gradually, and you eventually even get to hang out in a common area with some of the other slaves in between your 'customers'.

It's not a fate you'd have chosen for yourself, and you still miss your freedom, but all things considered, it could be worse.
