You get on all fours

You get on all fours for Emily. You can only imagine how the view must look for her, presenting your ass to her with your cock hanging out below her. How humiliating it is. "Good boy John." she says. "You are so beautiful." Your cock had started to soften, but her words makes it throb once again. You are beautiful. And your sister will think you are even more beautiful plugged up. Suddenly, you feel something intrude on your backside. It's her finger. "I will go slow John. I will just use one finger, but you will need to get used to the sensation." She pushes the finger into you, gently, slowly. You feel your entire body pushing against it.

You were expecting your entire body to reject it, but you can't reject Emily. And it doesn't feel terrible. It feels strange, sure. It's a sensation you've felt before, one that you previously rejected, and suppressed in your memory. But it feels oddly... nice. A moan escapes your lips as your sister pushes her digit deeper into your hole. Then suddenly, it starts going in the other direction. You feel her slowly exiting from you. You don't want this feeling to ever end. Her being inside you feels right. Then suddenly, her finger is out of you, making you feel oddly empty. But it doesn't take long before she puts it back into you again, and everything is once again right in the world.

Your sister fingers you for a few thrusts. As she pulls out of you, you're once again expecting her finger to enter you, when you suddenly feel cold metal push against your opening. You instinctively pull back. Your sister grabs you, and starts gently rubbing your hair with one hand. "Now now sweetie. Just stay still. Won't you be good for your sister? You are ready for this. I love you."

You don't manage to get out anything more than a whimper in response, but you stay still for your sister. You feel the cold metal against your skin once again. You know she would never hurt you, as you steel yourself for what's about to come. You feel your rectum widen, as the cold metal of the plug goes deeper and deeper inside you. This is nothing like her finger. It's more than twice as big at its widest point, and it is currently entering your asshole. But the feeling isn't uncomfortable. It's new, but it's not scary. Your cock is aching, your entire body is shaking, but you love it. You accept the feeling you once tried to suppress. You love having something up your ass.

You moan as you accept the plug deeper inside you, until suddenly, the pushing stops. It's all the way inside you. Your sister has managed to push the plug all the way to its grip. Your sister throws herself on you, hugging you tightly, her naked skin pressed against yours, before turning you around to face her. She is absolutely beaming. "You did it John! I told you that you could do it. I'm so proud of you!" She reaches in for a kiss. It's a long, deep kiss. Your two tongues wrestle with each other, your hands start exploring each others bodies. She takes your hands in her own, guiding them to her breasts, holding them there tightly, as you make out with each other. All these sensations would be overwhelming by themselves, but they're amplified by the fact that you got a metal plug deep in your ass. You are in heaven.

After a while, Emily pulls away from you. "Now I did promise you a reward, didn't I?" She gestures at your rock hard cock. "I think someone here deserves a a little release." She is right. Emily has had you on the edge for what feels like an eternity now. Your cock is glistening with precum, and it twitches with your every breath. "I don't wanna blow you in the bathroom John. Get on my bed, I'll be right over." You obey without question. You sit down on the edge of her bed and glance down at your cock. This is the first time you've been unlocked and by yourself in weeks. Your free cock is leaking. You wanna do nothing more than touch it. You know it would be the biggest orgasm you would ever have had. But you steel yourself, knowing what's in store for you, as soon as Emily arrives. The wait is no more than a few minutes, but it feels like a lifetime.

Then suddenly, Emily enters the room. Her naked body is glistening with sweat from your previous activities, making her entire frame shine. You look at her as she seductively moves towards you, her nipples hard from excitement, and her pussy still dripping. She has the cage in one hand, and her locket fastened around her neck, a reminder of what's to come. She gets down on her knees in front of you, and looks up at you with a sultry gaze. She takes a hand, and brushes it against your cock, making your entire body shiver just from her touch. You've worked so hard for this reward. You won't let this moment end just yet. As you think that, she moves her hand to your plug, gently pushing it out, not even half an inch, before pushing it into you again. You moan loudly at the sensation of the plug moving inside you. This is gonna be a challenge. "Please mistress..." you mutter.

She looks at you mischievously. "Please what John? Please stop sucking me off? Is that what you were gonna say?" You've really gotten her going now. "Now I know you have been through much today John. You've been so good to me today. I'm proud of you. So that's why I am going to suck my good little boy dry. My good little plugged up boy." As she says that, you can feel her tongue on your shaft. It starts at the bottom, before slowly working its way up the underside of your length. You bit your lip and grip her sheets, as you try to fight back you climax. You don't want this to be over in just a minute.

"Oh is that too much for you John? Is my big brother not even going to last for one minute?" She chuckles, as you suddenly feel her lips envelop you. You moan loudly as your sister starts pushing your length down her throat. The feeling is overwhelming. She goes down inch by inch, and you have to put all your willpower into not shooting down her throat. Your sister wouldn't like that. Not unannounced. You sister takes all of your shaft with ease. You are not small by any means, but your sister is an expert, clearly well practiced. The thought of that alone makes your cock throb in her mouth. She swirls her tongue around it, and you moan as she starts pulling back off your cock. As she pulls of your cock, you hear her take a deep breath. A string of saliva hangs between your tip and her lips. It's an image that instantly etches itself into your brain forever.

She looks up at you, smiling. "Good boy. That's more than a minute." She takes your balls in her hand, playing with them, traces her finger across them, as you once again have to steel yourself not to cum. "I don't think you'll last five minutes at this point John." she says, licking your tip. "How about this. If you last five minutes, there's another reward in it for you." She takes your cock in her mouth once again, before you even get a chance to reply. You instinctively start thrusting your hips as she pushes you further down her throat, pushing her hands on your thighs to hold you still. "Wh.. what reward mistress?" you ask, barely able to form a sentence.

She pulls off you once again. She can see that you are barely holding on. She smiles deviously, as she pulls her tongue out and licks your shaft from bottom to the tip. "If you can last for lets say... three more minutes. I'll let you fuck me." She's throating your cock again, before you can even react. As your mind processes what she just said, it's too much for you to manage. You let out a deep moan as you cum deep inside her mouth, with no warning. She doesn't hesitate for a second, clearly expecting your load. She stays etched to your cock as she takes rope after rope of your cum down her throat, swallowing every drop of it.

You've been tormented for what feels like hours, and as you finally get release, you fall back exhausted on your sisters bed. As you lie on the bed, eyes closed, catching your breath, you hear a click. You are back in the cage. "Good boy John" you hear your sister say. "I knew that would get you over the edge." You look at her, as she sniffs her armpit. "Jesus John, you did a number on me. I think we have to take another shower."

You get into the shower with your sister. She teases you during all of it, intentionally rubbing her body against you as much as she can, letting out a little giggle or an "oops" as you both clean each other. You let out frustrated groans, as your cock is back in its restraints, pressing against them with every touch of her body. You are back to her usual torment, but now it's not only your cock that she has control over. You also have the plug deep in your ass. Which your sister is quick to remind you of, as she accidently grazes it multiple times during your short shower together, each touch of it making your body shiver.

As you clean the bathroom after your escapades, your sister comes in with a fresh pair of change for you. Panties, bra, stockings, a skirt and a crop top. You look quite cute in them, you think, as you look at yourself in the mirror. Your sister shaving you really made a difference.

You look like quite the cute girl.
