I just imagine having fun watching some kinky porn with my girlfriend, and she wants to indulge me and my naughtiest kinks, cuz she's a really sweet and loving girlfriend. 
So after some coaxing and edging, she finally gets me to admit that I really like the idea of being a cuckold while she becomes a snowbunny....

Then we start watching interracial porn together, while she's giving me a handjob, teasing me and playing with me, making me orgasm every time the girl in the videos orgasms. Unknowingly conditioning my brain to love interracial porn even more than I already do.... I know what she's doing but I'm too horny and turned on to tell her to stop, to Lost in the pleasure and desire for one orgasm just tell her to stop....
But then as this continues on for the next few days watching porn together, she plays along and refuses to let me have sex with her. Telling me I'm a good little cuckold and that I don't get to have sex with her. This turns me on even more, she knows it. 
She does her research, about the Kinks and all that, and soon she's literally cuckolding me with interracial porn, and masturbating in her room with the door closed and locked, pretending like she's getting fucked, but we both know it's a role-play, but it just makes me fantasize about it more. 
Then I get this really crazy idea to introduce her to my old friend from Reddit, going back to Reddit after thinking I had finally escaped it. 
I introduce my girlfriend to Keepinitfree.... Big mistake 
Everything starts out fine in a three person group chat, hanging out and chatting. And we get to know each other, and then we meet in person, chatting some more, and my girlfriend knows that all of this is leading to some kinky fun time in the future, that these were just preliminary conversations that needed to happen in order to get comfortable with each other...
But now it's time to talk about the kinky stuff and both me and my girlfriend are getting excited, I can see it on her facial expressions, and little cues that she does with her body, like squeezing her legs together and biting her lip. We've signed the contracts, for safety and all that. That this whole King stuff wound effect our marriage, but obviously my girlfriend is told that it's just your normal contracts, it's nothing serious....
And then we're about to get to the kinky stuff, and my friend says as much, "now we get to the exciting parts how'd you go mister, it's time for me to get acquainted with my new slut" 
My girlfriend's face is a little bit confused. I'm also confused, and it shows on my face, and my girlfriend's about to say WTF when she sees me standing up slowly and slowly moving to the Lord's the door but not quick enough. Keepin stands up quickly and shoos me out, and as she's doing that, I can hear my girlfriend asking all kinds of questions like "wait what? What's going on? Doesn't he have to be in here for-" 
Abruptly her voice is cut off by the door, the bedroom door, the one that we sound proofed, so that people couldn't hear us having sex in the house next door. 
My cock is getting rock hard from being in this kind of situation but at the same time I also feel like I just abandoned my sweet innocent girlfriend in a chicken coop with a deadly fox, no a wolf. I don't know what's going to happen to her or what's happening to her right now, all I know is that I haven't seen me turned on and I can't help but reached into my pants and start rubbing my cock furiously, and breathing heavily. 
I'm so turned on but also a little bit scared of what's happening in there. I try the door but it's locked. Locked?! 
I knock on the door but no answer. I wait patiently at first and then impatiently after 2 hours, and then 4 hours....
Finally the door opens, and my friend walks out, a Sly smile on her face, as she's dressed and ready to go, before she gently grabs my chin and thanks me for a great time. I asked her if there's anything else going on but she just smiles wickedly and says "you'll have to wait and see" 
Then I quickly dart into my bedroom, and see my girlfriend laying there sweaty, and wearing nothing but a pair of panties that are completely soaked, looking at me with this look of complete submissiveness, the kind of face she only gives me when she's completely broken, like right after an orgasm... I also know that she has this cute little collar around her neck, I gently look at it with my fingers moving it around a little bit, and then as she sits up, I can see it's padlocked behind her neck, and my cock goes hard. Her cheeks are blushing bright red as she knows exactly what I'm discovering. 
I try to ask her questions but she won't say anything, she just says that she needs some time to herself, to process everything. 
I decided to give her space, telling her I'll go and watch some TV or play a video game, leaving the room. I can hear getting up and closing the door behind me, and then I wonder if maybe I should have stayed and cuddled with her...
I try the door, it's locked...😳 My cock hard again but I try to push it away because I know she's probably just tired and want some rest. But she's my girlfriend she doesn't need a lock the door. Right? Fuck. And it soundproof too...
I call my friend, no answer. I call again, no answer. Three calls later, I get a text:

"What is it loser?" 
"What did you do to my girlfriend? She's....shes not"
"I'm not telling you, that's for you to find out, if she didn't tell you herself then I'm certainly not telling you." I can hear the evil devious grin on her face as she hangs up

Fuk u/Keepin_it_free has got me so wound up on this whole Chastity and snow bunny pink, it's crazy. Such a mind fuck. I can't even blame her cuz I'm beginning to secretly like it. Even though I know it's bad. It's so bad. It's so bad and I don't want this to happen
