At this point she has

Either word has gotten around about Erin's new model, or she has invited quite a few people, because Lexi, soon finds herself occupied by the first cock of the day, and the line behind him seems to go on forever. She's unable to exercise much in the way of technique, with her neck bound within the contraption and her head basically immobilized, but she does her best at first, doing what she can to service this strange man's cock. Not something she'd normally do, but like this, nude and bound in this store, helpless and her body being so wonderfully stimulated, she can't help herself. She looks up into the stranger's eyes as he fucks her mouth, him seemingly regarding her as little more than merchandise, a thing to amuse and pleasure him. A thought that causes Lexi to groan lustfully, a sound that's muffled due to the fact that her mouth is currently full of cock. In her current state, she doesn't even want to contemplate the end of the weekend and having to go back to her normal routine. Which of course makes her contemplate it. Which soon turns into fantasies of being nude and bound at the office, her co-workers and boss and clients all using her body for their own pleasure. And of being bound under the table at brunch with her friends, them taking turns having her service each of them, among other scenarios. In fact, at the point she's at, she's unable to think about any aspect of her normal life without it turning into her being in bondage and used like the fuckdoll that she is.

It's not long though until the first man cums, pulling out and finishing on her face, covering her in his cum, before he is quickly replaced by the next one in line. And on it goes, one cock after another for the bound, busty blonde to service. Some of them cumming on her face, some in her mouth. All the while, other patrons trying out paddles and crops and floggers and other things on her bare ass. People talking about the contraption with Erin, and she even sells a few of them. Though she does turn down the offers for the model in the contraption. Lexi loses track of not only how many dicks she's sucked, but of time as well. But eventually Erin decides that she needs a little break to stretch, clean up, get a little something to eat. So Lexi takes her up on it, and realizes that she's spent four hours in this device. She walks around the shop some, stretching out her limbs, and oddly, feels a bit embarrassed now about her lack of clothing. Perhaps because she's not in bondage, she thinks to herself with a little giggle.

After her break, Erin directs her into the back of the shop, and says to her, "Time for you to model something from my clothing line." Lexi merely nods in response, ready and eager to do whatever Erin asks of her. Erin then produces what looks like nothing more than some chains connected to each other. And that's pretty much what it is. The skirt consisting of a chain circling her body, and resting low on her hips, along with strands of fifteen inch long chains hanging off of this, like a grass skirt, but made of chain instead of grass. It covers nothing, and seems more like jewelry than clothing. The top is much the same, a chain going around the back of her neck, with and splitting in two on either end, the inner chains connecting in front of her, a bit below her breasts, the outer chains connecting behind her back. And between each of those, forming something akin to a bikini top, a series of chains draped over her breasts. Again, it covers nothing, just elaborate body jewelry. And to finish off this outfit, a chain choker, with a larger ring connecting either end of the chain.

With the model dressed, she is led back out into the store, towards the front. She is directed up a few steps and into a small room. Erin then has her stand on a raised platform with a pair of poles on either side, with chains and cuffs at the tops and bottoms of each pole. Lexi is quickly cuffed, and the chains are pulled tight, so she stands in a a spread eagle position. Erin then leans in and gives her a quick kiss on the lips, "And just so you don't get bored, here's an extra bonus" And with that, produces what looks like a weird insect, and places it on Lexi's pussy. The legs clamp onto her labia tightly, painfully, the head pushes up against her clit, and the tail pushes inside of her, nestled snugly against her g-spot. The bugtoy begins vibrating, the head portion offering a variety of stimulations, vibrations, nibbles and sucks, the tail vibrating and and wriggling. Causing Lexi to gasp. "Oh, and you may want to try to stay still and quiet, wouldn't want people thinking you're not just a mannequin. Or maybe you don't. Your choice." And with that, Erin steps out of the room, and the curtain opens, revealing Lexi to the street outside, the platform she's standing on and bound to begins slowly turning, putting the helpless, naked but not naked model as the toy sends an endless stream of intense, excruciating and frustrating pleasure through her body.

She doesn't even try to hold still or be quiet. The combination of everything, being so exposed so publicly, the bondage, the eyes immediately on her, and of course that evil little toy have her even more turned on than the first device. Whenever the platform has her facing the street, she looks out into the growing audience, her eyes looking into theirs, seeing their desire and amusement, seeing their phones coming out, recording this. Knowing fully that people she knows are going to see this. A thought that she's sure will horrify her later when she isn't so horny, but at the moment, she finds it incredibly arousing. Thoughts of her pig of a boss seeing her like this, jerking off. Or maybe inviting her into his office to punish her for being such a naughty girl. She briefly wonders how long she's going to be in this new predicament, but decides that however long it is, it won't be long enough.
