Just the wrists

You ask Natalie to take off her jacket and put her hands behind her back, as you wonder whether it still counts as 'taking someone's advice' when the advice given is what you were going to do anyway. She complies, after giving you a curious look.

Looking down at Natalie's arms, a few ideas come into your head as to how to proceed. You opt to try and go for something really secure, so you position her arms so that her wrists cross over, then loop the rope around horizontally a few times, occasionally nudging against her back and hands as you do. Then you repeat the same vertically, doing another few loops. There's a fair bit of rope left, but not quite enough to actually do anything with, so you end up tying an unusually large knot towards the top of the bundle of rope, before stepping back to admire your handiwork.

It's... well, it could be better. From what you can see, it looks tight enough without being dangerous, although the multiple coils do look a little sloppy. Natalie's pose is nice, though; The way her arms are positioned accentuate the shape of her rear, emphasizing the flaring of her hips and the size of her cheeks.

"So, do you want to get a timer out, or..." Natalie trails off as you reach for your phone, loading up the timer and punching in 15 minutes, then flashing it to Natalie.

"Ok... Go!" You say, as you sink onto the sofa, tapping the centre of the phone as you sink into the giant pillows.

Natalie seems pretty calm at first, seeing if she can just wriggle out of the ropes, but has no luck. Extends one arm while retracting the other, calmly swapping after a few seconds, back and forth. This continues on for a good few minutes. Watching her move like that is certainly enjoyable, like watching an exotic dancer in the early stages of a set, swaying back and forth, hips rocking as she does...

The phone beeps. 5 minutes have gone by. Natalie is starting to look a little less cool. Her movements are less uniform now, more jerky. Long, slow pulls are replaced with staccato tugs at her wrists, the ropes failing to budge. She's no longer planted in place, but travelling around the room, step by step, as her tugs throw her off balance and she moves to compensate. As she turns around, you see how the position of her arms pushes out her chest a little, not quite straining against her T-Shirt, but certainly taking up the little slack that was in it; The jerking of her arm causing her breasts to bounce a little, which you find entertaining.

You're starting to get a bit excited now, too. A part of you seems to be empathising with her struggle, wondering how the ropes feel, and how frustrating it must be to not be able to get them off. You feel your face start to redden again as you imagine the panic that must be setting in as the time counts down, wondering what cruel fate may await her, should she fail. A fate you control. You start to consider your options should she fail, but...

"Huh." You say it out loud, but Natalie doesn't seem to notice. Not that you meant for her to notice, but your emotions caught you off-guard. Or, well, your lack of emotion. As soon as you started thinking of what you'd do to Nat, your arousal plummeted. Not only does nothing really come to mind, but you just didn't find it interesting at all. Oh well, back to watching Nat.

The phone beeps again. 5 minutes remaining. Natalie seems openly frustrated now, giving one final tug before turning to you. She's slightly ruddy now, a fine sheen of sweat coating it, while a few strands of hair are stuck to her face.

"Going and getting some scissors is probably against the spirit of the game, isn't it?" Nat sounds like she's forcing herself to stay calm, voice low and somewhat monotone as she speaks at a rapid pace.

"Yeah, I'd say so." You try and feign calmness yourself, not wanting to give away that watching her squirm is getting you a bit hot and bothered.

"Yep. And these ropes are expensive."

At that, she takes a different tack - she tries to get her arms out from behind her. She half succeeds, managing to get them past her bum and into the crook of her knees. However, she's still standing. And she can't hold this bent-over position. Or bring her arms back, now that she's stuck them under her knees. She tries to **** them back, but fails, instead just rolling over onto her side.

You jump up at this, fearing your sister may have hit her head. "I'm Okay!" she shouts back, attempting to reassure you. You're still up now though, interested in moving around her, so you can see from a few angles. She's struggling hard now, unable to do much more than keeping pressure on the ropes, each pull and relax not budging all that much. She rolls over, more out of frustration than a realistic attempt at gaining freedom. Now it's exciting again.

You feel your skin flush, deeper than previously. You cross your arms tightly, hugging yourself as you look down at her, shifting your weight more onto your right leg as your left leg presses against it, subtly squashing your thighs together. The panic is starting to show in her eyes - she's trying not to, but now you're standing in front, she can't help but keep making eye contact, even if only for fractions of a second at a time. Likely a temptation to beg for mercy. Christ, that's hot.

The phone double-beeps. One minute. Natalie's demeanour changes almost instantly. She rolls quite cleanly from her side, onto her back, rotating so that you're almost directly at her feet. She spreads her legs out as much as she can, which makes you feel a little uncomfortable. Though, looking at her face, she's not frustrated anymore, but calm. Actually, a little happy. She looks you in the face as her hands wiggle again. Well, her fingers. After a couple of seconds, she's managed to grab one of the loose strands, then the other. She tugs, and tugs again, and manages to wrap a finger around the knot. A few seconds later, it's loose, and then her wrists are. She's out, hands separated and waggling at you. You don't bother to stop your phone's timer as it goes into the 10-second countdown and ends, instead just offering your hand to help her up.

"Not bad for a newbie." She strains towards the end of that sentence, as she pulls herself up, with your help. "I mean, you got it tight enough to be restrictive, at least - you wouldn't believe how hard it is to get some people to not be so timid. But, really, you didn't need that many loops to restrict movement, and the knot was way too easy to access thanks to the loose strands." She raises her right arm, holding your shoulder now as though giving a pep talk, as she uses the left to brush her hair away from her face. "So, did you enjoy the show? Did I awaken the dormant Dom inside of you!"

"Not really," you say, offering a non-commital half smile with a shrug. "I mean, the struggling and stuff looked fun, but when I thought about what forfeit I might give you, I just went 'bleh.'"

"Huh. Interesting. Maybe... Huh." Natalie withdraws her arm, raising it to her head instead. "So you still liked what was going on, but didn't want to give out a punishment?" You nod, slowly, not entirely sure, but near enough to what you were thinking. Natalie pauses for another few seconds, seemingly deep in thought before coming back to reality, grabbing the rope from the floor before turning back to you. "Lets come back to that next round. My turn now."
