Big gym sesh over, time for Chelsea

Rowing, thrusters, pull ups and kettle bell swings. Your workout looks like something out of crossfit but it does the job. After 30 minutes you are dripping in sweat. Your pants are clinging to your ass and you've been getting a lot of looks around the gym from guys and girls. Normally you'd take the opportunity to flirt a little but you unfortunately didn't have the time.

You walk back to your room, right on time you turn the corner to your room and see Chelsea arrive and knock on your door. You quietly walk up behind her as she looks a little distracted

“Eeek!” You surprise her and you reach from behind her and open the door.

She doesn't even turn to look at you, just obediently walks through the door. You feel a little bad cause you're about to be really mean but you've convinced yourself Chelsea needs it. She needs to know you have the control and she will take what she's given and not be a brat about it.

You shut the door behind you letting the click of the lock ring out through the room. She stops in the middle of the room and turns to face you her face drops into on of confusion when she sees you.

“Uhh did I come early? Do you still need to shower?”

You smile and walk towards her. The intimidation factor was very important here you needed her the part of the brain where thinking happens to switch off and the part where mindless obeying happens to switch on, at least initially anyway.

As you walk towards her she takes a little step back and backs into a wall “Hmm not a shower, I was thinking a bath instead.”

She's up against a wall looking very **** and you can hear it in her voice as she squeaks. “But there's no baths in the dorms?”

You bring your face very close to hers before whispering in her ear.“Yes, but I have your tongue.”

Her eyes go wide and she just sort of freezes for a second, you're sure if she could she'd back away but shes against a wall and has nowhere to go. You raise your arm and lean your elbow on the wall she looks at you and then your sweaty armpit (immaculately shaved though, personal grooming is important).

She pulls herself out of her trance with a gulp and glances at you, you hold her gaze and you can actually see the inner struggle and after a very long 3 seconds you win and she brings her tongue to your armpit and takes a small lick.

You feel the tickle under your arm and resist the urge to giggle. There is a hint of a grimace on her face but to her credit she holds herself very well.

You know you have her now and you continue to push. “Again, this time do it properly.”

As you suspected earlier now she's done it once she's committed and like a good girl she resumes her duty. She takes a long lick and you shudder a little, the sensation of a tongue under your arms is not something you're familiar with. After a short while you stop her and move her to the other side.

“Mmmm good girl I think you're enjoying the taste of your mistress. Or maybe you're just a nasty slut who wants to be treated even more roughly. Hmmm anyway I think its time to move on. My tits are especially sweaty.”

You peel off your top and sports bra. The lycra sticks to you as you pull it and your large tits bounce free. You are pleasantly surprised that without asking Chelsea continues your tongue bath.

“That's it slut get right into the cleavage and under my tits.” You're actually quite impressed she's getting more eager as she goes on, the way her tongue is teasing your nipples really starts to wind you up.

“Mmm I think you'll be licking my tits more often slut but now you know where you need to be.” You don't need to say anything, she drops to her knees in front of you and slowly peels down your shorts and panties.

Your pants come off and she stares at your pussy for a second before diving in. You think about holding her head but the fact she's eating you so enthusiastically is even better.

“You were right yesterday, it has been too long since you ate my pussy. This really is where you belong isn't it”

“Yes mis-tmmmpphhh.” She starts trying to talk and you just shove her face back into your pussy.

“I phrased it like a question but really I, Ahhhh mmmmm yeeeessssss.” This time its your turn to be cut off as her tongue dances on your clit.

You grab two big handfuls of her hair and prevent her from pulling away and you squirt all over her face. However just like a good girl should she doesn't think of stopping, continuing to pleasure you the whole way through your orgasm.

You catch your breath and look down to see Chelsea patiently looking up at you you can see in her eyes she's thinking “I've been a good girl now can you please fuck me.” But again that would be giving her what she wants and today is all about Chelsea understanding that you're in control and she'll take what she's given.

“Hmmm I'm nearly all clean...” Her face drops as she realises what's coming.

With a big smile you turn around and look at her over your shoulder, the look of internal struggle is back but the same as last time she realises she's already too deep and can't stop now. You smile as you feel her tongue on your ass cheeks. After cleaning both cheeks you again feel her hesitate.

“Nuh uh, girls that don't finish the job don't get to cum.” You bend over, you don't turn around or anything you're confident she will choose properly.

Just as you finish that thought you smile, you feel her lips against your butthole and soon her tongue. “That's it slut, eat my sweaty ass.”

Unlike Scarlett she's just not all that enthusiastic so as much as you enjoy having her in that position you know you won't cum, but you let her rim your ass for a while just to really hammer home where her place is. After a short while you stand up and turn around. She looks at you from her knees, eyes full of hope at what she thinks is about to happen.

“On the bed, now.” She almost gets up too fast and betrays how badly she wants this.

"Oh shes going to be mad..."

She gets on your bed and lays down. You smile as you reach below the bed to grab your restraints and affix them to her wrists. The restraints are a nice leather and buckle so nothing too harsh but that do hold her tightly and without any circus level bullshit should be impossible to escape from.

She gives you a bit of a smile while looking confused “Uhhh kinky?”

She remains the good girl and you move down to the other end of the bed. She starts getting a little more confused as you bind her first leg.

“Umm Issy what's all this?” She's still isn't fighting back so you quickly secure her second ankle and like that the cheerleader is bound and completely at your mercy.

You can't help but hide your smile now “Oh, this? Just one more thing I promise.”

She only gets more confused as you hold up a ball gag. She tilts her head but doesn't fight it as you gently push the gag into her mouth and fasten it behind her head.

“Ahhh now the fun begins.” You tighten the restrains until all her limbs are spread eagled.

“I see you're looking a little confused and I have to be honest you're completely right to be. The short version is I'm a total bitch and the long version is I know you want me to fuck you until you pass out but I know you think you have some sort of power in this relationship and I need you to let go of that and completely become my ****, only then will you get what you want. For now you'll just get what you deserve.”

You can see the frustration in her eyes as she realises she's not going to get what she wants. “Mmm mmmm mmmmm.”

You ignore her and pull two belts out of your wardrobe, She immediately stops and stares looking a bit scared. “Haha oh no I'm not going to use these to punish you, although...”

“Mmmpphh” She recoils a little.

“Haha no no, but in a little while you might wish I'd used them to tan your cute little ass.” You loop them both around her left leg and don't make them too tight.

She's obviously confused but she wont be for long. “So I told you yesterday not to come until today and did you?”

she shakes her head and looks fairly genuine. “Well you're in luck cause today you're gonna have all the orgasms you can handle and then some.”

You pull your vibrating wand out of your draw and there's an immediate look of realisation in her eyes and you see her struggle against the restraints.

“Tsk Tsk, its way too late to run away, you're in for a long day beautiful.” You hold her leg and bind the wand to it using the belts.

You make sure its tight enough so it doesn't move and you position it perfectly for maximum stimulation. You give a a quick smile and turn the wand on. “Mmmmmm mmm”

“Oh stop being such a baby its only on the lowest setting. Luckily I bought a very expensive one so it comes with a lot of settings. And this one I think you'll love.” The Wand is set on a low setting and you program it so over time (10 minutes or so) it gets slowly stronger until hitting maximum and then staying there until the battery runs out.

Her eyes are staring daggers at you while you listen to the muffled sounds of her cries.“ I hope you didn't have anything else planned cause its gonna be a long day for you. Oh dear if looks could kill I'd be in some serious trouble, I'm just gonna do something about that.”

You pull out a blindfold and cover her eyes,“MMMMMM MMMMMPPHHHHH!” you watch her squirm uselessly.

"Hmmm you're bound, blind and you'll be **** to cum over and over but there's no guarantee you'll be thinking about me the entire time. Oh wait i've got it." A truly evil smile comes across your face as you realise you are well and truly crossing a line. But at this point you a little drunk on your own power in the situation and definitely not going to stop

You grab your disgusting, sweaty panties and pull them over her head so your crotch lines up directly with her nose, then you make sure they are tight so she cant escape. You give her a quick kiss on the cheek before whispering. “I'm going out I'll see you later, now I want you to think about whether you're going to keep trying to get your own way or whether you're going to completely become my slut.”
