A collar.

"Ahhh.. Oh! Here it is!" Sarah calls after a moment, straightening up. She holds a high quality, sturdy leather choker, jet black, and about a centimeter wide, the leather band connected in a loop by a shiny stainless steel love-heart, and a small size adjuster on the back to fit different sized necks.

"Give me that." Tom growls. His hand outstretched. Sarah throws the collar at him, before smiling wolfishly at Nicole and resuming her inspection of her trove of toys.

"Kneel, slut." Tom commands, looking at Nicole. Nicole complies without hesitation, kneeling as close to him as possible with her knees spread aside to allow her hands access to her nethers. She quickly starts fingering her recently deflowered pussy with one hand, while also reaching around her back to finger her asshole with the other. Tom's gooey cum spills from her ass quickly as she breaks the tight seal holding his seed inside her.

"Do you want to be my fucktoy, Nicole?" Tom growls to her, resting the collar over his half-hard cock, drawing her attention to it.

"Yes Master. More than anything I have ever wanted." She replies, her fingers squelching as her eyes remain locked on either the collar or Tom's cock - you can't tell which.

Sarah has turned around to watch Nicole's submission, moaning softly to not ruin the scene as she applies a Hitachi she's grabbed from her container to her clit.

"Understand that you're agreeing to be my ****. Your body is mine. I'll use every hole you have, whenever I want, and I'll let others use it, whenever I let them. I will tattoo it, I'll pierce it, I'll whip it." Tom continues.

You idly notice as Tom speaks, that Miranda and Matt are getting up, Matt looking a bit embarrassed and Miranda upset - her pussy was leaking Matt's cum, but her moans had never reached their crescendo. They both seem to not fully understand what's going on, so they quickly take a seat either side of you on your couch.

"John, what's happening?" Miranda breathlessly whispers in your ear, smelling of feminine sweat, wet pussy and pungent cum.

"She's.. becoming a sex ****.." you croak to her in disbelief at your own words.

"WHAT?" Miranda whispers back, just as stunned as you.

"Master, I want you to break my fucktoy body to your liking. I want you to continue teaching me how good it feels to be nothing but a sex object. I'm designed to be fucked by you, and by anyone with a big strong dick. My body is yours whenever you or your friends need to deposit cum deep inside a warm hole, but please let me fuck other studs like Sarah! I was born to be a slut!" Nicole finishes with desperation. Out of the corner of your eye you see Miranda looking between you, Sarah and Tom, clearly in disbelief at what is coming out of Nicole's mouth.

"I don't care who else you fuck when I'm busy or fucking some other slut, so long as you're wearing this collar and you're wet and ready for me whenever I want you, fucktoy. If you disobey me, you'll never get my cock, or any of my football buds' monster cocks, ever again, and from what I hear, they're almost as good as me." Tom finishes, glancing at Sarah quickly.

"Fuck yeah they are." Sarah interjects as her head is half rolled back, seemingly imagining the football jocks pleasuring her instead of her vibrator.

Tom holds up the collar and offers it to Nicole. Nicole leans forward and allows Tom to fasten the leather and steel around her neck, tightening it enough so that the steel heart presses gently against her throat at all times, reminding her of her new place. Nicole moans as she's collared, an inferno of lust burning bright in her corrupt eyes as she resumes her licking of Tom's balls, awaiting instruction from her Master.
