Emily is standing at your front door. She's standing there because you texted her the moment your wife left to have lunch with her friends. You couldn't help but share the news that your wife had let you clean your cum out of her pussy and that she'd tentatively expressed that she might be interested in letting you clean someone else's cum out of her.
You didn't invite Emily over. You never do. She just shows up because she likes toying with you. She likes making you nervous that your wife is going to walk in while she's there and see that you've been getting some of your cuckold needs met by another woman. You know you're playing a risky game, but you can't help it. Your desire for humiliation - the kind that only Emily offers - is so strong that you can't help but get in touch.
"Do you want to come in?" you ask.
Emily shakes her head and says, "I want you to come out, cuck."
"I...I don't think that's a good idea," you reply.
"I want you to come out and get on your knees in front of me, cuck," Emily says, ignoring your concern. "I want you to see you on your knees. I want to see you look up at me with those desperate eyes."
"I...the neighbors could see, Emily," you say.
"Your wife will see me standing here when she comes home if you don't get the fuck out here right now, cuck," she replies sharply. "Because I'm more than happy to hang out for a few hours while she's out to lunch. I'm more than happy to introduce myself, to tell her how I know you, to tell her all the disgusting things you've done for me. Do you think she'd enjoy that, cuck? Do you think she'd enjoy learning that her husband is a fucking cum pig that's eaten a hot load from my pussy, or taken a hot load directly from the source? Do you think your wife is ready to know just how much of a dirty little cum whore you are?"
You shake your head.
"Then get out here and get on your knees," she instructs.
You surrender because you know Emily will happily tell your wife everything. You knew that was the danger of indulging in her dirty game from the start, and yet you couldn't resist.
You step out of the house and fall to your knees in front of her. She rewards you with a smile and then reaches down, grabs a handful of your hair, and pulls hard enough for it to hurt.
"I like playing with you, cuck," she says. "You're pathetic, but you know it. You embrace it. You fucking crave being made to feel like the pathetic cuck that you are. I like playing with a man like that. I like showing you what you are. I like making you own what kind of man you really are."
She releases your hair and swiftly shoves three fingers in your mouth. She bends over and pushes them to the back of your throat. She doesn't quite trigger your gag reflex, though, instead choosing to keep your mouth stuffed with her spit-soaked digits while you remain on your knees and surrender to her.
"Does this make you think of how you sucked cock for me, cuck?" she asks as her fingers move in and out of your mouth. "Does this make you think of how you got on your knees in front of a real man, took his fat dick in your mouth, and sucked like a fucking whore just because I told you to?"
You nod as you think of the cock that filled your mouth and deluge of verbal humiliation Emily treated you to while your lips were stretched around his thick shaft.
"Have you stroked that pathetic little dick of yours while thinking about being a cocksucker, cuck? Have you given yourself an orgasm while fantasizing about having his dick in your mouth again?" Emily asks.
It's hugely embarrassing, but you nod. You've fantasized about it multiple times since it happened. All you have to do is close your eyes and you can feel his cock in your mouth again. You can feel it stretching your lips and moving over your tongue. You can feel it swelling up as he gets closer to orgasm. You can feel the cum spurting onto your tongue and overwhelming your taste buds. You can feel every bit of it.
Emily pulls her fingers from your mouth, stands up, and says, "I thought so. Let's go inside." You try to stand up but she puts a hand on your head and says, "You can fucking crawl, cuck."
You turn around and crawl into the house with Emily just behind you. She shuts the door, locks it, and leans against it as you turn around and look up at her. She looks exceptionally hot in a short skirt, a pair of knee high boots, and a tight long sleeve top that her hard nipples are poking through.
"Take your dick out," she instructs.
You unzip your pants and free your cock, which is very nearly erect from the humiliation you suffered outside your front door.
"Jerk off," she says.
She smiles as you play with your cock, seemingly because you're doing exactly as you've been instructed.
"Tell me that you enjoyed being a cocksucker," she says.
"I loved being a cocksucker for you," you admit. It's true. You loved it. You get hugely aroused just thinking about it.
"Tell me that you're a fucking cum dumpster," she demands.
"I'm a cum dumpster, Emily. I'm a filthy fucking cum dumpster," you say.
She laughs at your willingness to humiliate yourself. Then she lifts her skirt, pulls her panties down to her knees, and shows you her glistening, nearly smooth pussy.
"How did it feel to eat your load from your wife's pussy, cuck?" she asks while slowly rubbing her clit.
"It felt so good," you reply. "It was such a turn on. While I was doing it, she told me how she'd told her date about me, about the fact that I'm a cuckold and that I love that other men fuck her better than I do. She told him that he was the superior man. Then she shared that with me. She shared it while I was eating my cum out of her pussy."
"Mmm, she's starting to see you for the man you really are, cuck," Emily says as she rubs her clit faster. "You should be careful. I'm not sure you want your wife seeing the real you, cuck. She might not want to be with the real you. She might not want to be married to a cocksucking cum whore. She might not want to be married to a man that gets off on being a filthy fucking faggot, a man that gets off on being used as nothing more than a toy, that gets off on sucking dick and eating the fucking loads of strangers."
You know she's right, and yet there's a part of you that wants to hear your wife utter those words. You want her to make you eat another man's load from her pussy and call you a cum whore. You want her to make you suck another man's dick and call you a cocksucker or a faggot. You know you shouldn't want those things and you shouldn't ever try to make them happen, and yet the idea of it is so fucking hot.
Emily spins around, pushes her hips back, and says, "Eat my ass, cuck. Eat my fucking ass while I rub my clit."
You crawl forward, press your face between her tight ass cheeks, and rim her hole. You do it without hesitation. You do it with great vigor. You lick her asshole like your life depends on it and you find great joy in masturbating while you do so.
"That's it," she says. "Lick my asshole, you filthy fucking pig. You small-dicked cuck bitch. You nasty cocksucker. You fucking faggot cum dumpster!"
Her ass cheeks tighten and her moans fill your house as she cums while degrading you. Her legs tremble and she reaches back, grabs your hair, and pushes you as hard against her ass as she can, smothering you for a few seconds while she experiences the final moments of bliss that come with such a glorious orgasm.
She pushes you away, pulls her panties up, fixes her skirt, and opens the front door. "Thanks for the orgasm, cuck. Put your fucking dick away. No orgasm for you. Not until your wife gets home and only if she's willing to let that pathetic little thing inside her, and make damn sure you clean your mess out of her if she's generous enough to have disappointing sex with you."
She's gone before you can say a word. She slams the door hard on her way out. You take a deep breath to recover from the whirlwind of humiliation and pleasure that just enveloped you.
You tuck your dick back into your pants, zip up, and hope that your wife will be generous enough to let you inside her when she gets home.

Your wife is naked in your bed and she looks flawless. Her hair is spread out on the pillow beneath her head, her nipples are hard, and her pussy lips glisten with desire. You've just given her a full body massage that included quite a bit of breast play and a little bit of clit rubbing towards the end and you're hoping she'll let you provide her with an orgasm.
She sits up on her elbows, looks between your legs, and says, "You're quite hard, aren't you?"
You nod. You've been hard for most of the massage, both because you love touching your wife and because it's been nearly a week since you've had an orgasm. She didn't let you inside her the day Emily came over for a visit and she hasn't let you inside her any day since then.
Your wife laughs softly and says, "You're kind of small, aren't you?" You're so stunned - she rarely comments on the size of your cock - that you don't say a word. "At least compared to the other men that fuck me, that is."
You want more. You want to hear how unimpressive she finds your cock. "Yes, I am," you say.
She sits up, reaches out, and wraps her fingers around your stiff shaft. She strokes it a few times and says, "I can't even fit my fingers around most of the other men that fuck me, but I can do it with ease with your cock."
You're not sure why she's suddenly keen on humiliating your cock size, but you love it and you're quite certain she understands that you love it.
"I never really thought about it until I started fucking other people, but you really are too small to truly satisfy me," she says in a matter-of-fact manner that you find hugely arousing. "You like that though, don't you? You like that your dick is too small to satisfy me. You like that you cum too quickly to satisfy me. You like that you don't really know how to fuck me like I need to be fucked."
"Yes, I do," you admit.
"Just like you like the idea of eating someone else's cum out of me," she says. "An idea that most men would find disgusting makes your dick hard."
"Yes, it does," you admit.
"Are you close to cumming right now?" she asks while stroking you slowly.
"Yes," you say.
"Because you're thinking about crawling between my legs and licking another man's cum out of my pussy?" she asks. "Because that turns you on so much?"
You nod. You can't quite read the expression on her face. You don't know if she's annoyed that you're turned on by such things or if she's fascinated and eager to give you the very particular kind of pleasure you desire.
"Would you like to clean someone else's cum from somewhere else? Would you like to lick it off my breasts or my stomach, for instance?" she asks.
"Yes, absolutely," you reply with an embarrassing level of eagerness.
Your wife releases your cock, lies on her back, and beckons you closer. "Straddle me," she says.
You crawl forward until you're sitting across her stomach. She takes your shaft in her hand and pulls you a little closer until you feel the soft, warm flesh of her breasts against your swollen, sensitive cock head.
"Would you like to clean your cum off my breasts?" she asks.
"Yes," you admit while looking down at your beautiful wife.
She resumes stroking your cock, this time playing with your balls at the same time. "But you'd prefer to lick someone else's load off my breasts, isn't that right?"
You nod.
"You'd enjoy it if he was the one sitting astride me, if he was the one I was stroking, if it was his cock and balls in my hands. You'd enjoy that, wouldn't you? You'd enjoy watching me jerk off another man's cock so I could have him cum all over my big breasts so my husband could clean up his mess, wouldn't you?" she asks.
"Yes," you answer. "Fuck...yes, I'd love that."
You're still not entirely sure if your wife's aim is to give you pleasure or if she's probing for just how depraved you are as she gathers evidence for whether or not she wants to stay with you. All you really know is that it feels fucking great and that you'd absolutely love to watch another man cum on her tits before she invited you to clean them.
"I think I'd like that too," your wife says.
Your dick swells in her hand as she says the one thing you really want to hear.
"I think I'd enjoy making one of my dates cum all over my breasts - particularly after he'd fucked me to the kind of orgasm I need - and then inviting you to clean them up," she says.
"Really?" you ask.
She nods. "I think I like that you want to clean the cum of other men out of me and off of me. I think I like that you're willing to share that desire with me. I think it makes me want to get a little bit naughtier with some of the men I go on dates with. I think I might actually let you clean someone else's cum from my breasts."
She tightens her grip and strokes your cock faster.
"For now, though, you're going to clean your own cum from them," she continues. "When you're done, you're going to get between my legs and spend quite a bit of time down there. You're going to make me cum as many times as I want."
"I will," you say. "I'll do anything. I will. I'll make you cum as many times as you want."
You're moments away from cumming. Your wife's hand feels so fucking good on your cock and you wonder if she's ever given one of her dates this kind of handjob. Has she already made lots of guys cum on her tits and just not told you about it? What a hot fucking thought.
"Cum on my breasts," she says. "Cum on my breasts and then clean up your mess. Devour your cum."
You cum on her tits. You shower them with more than a week's worth of build up. She smiles as she admires the volume of your cum and listens to the sounds of intense pleasure you can't help but release.
She releases your cock and balls and you back up, drop your head to her breasts, and immediately start licking and sucking your load from her soft flesh.
"Mmm, that feels nice," she says. "And I'm almost certain it's going to feel even better when you're licking up someone else's cum. I'm going to make that happen, honey. Fuck, I'm really going to make that happen."
She sounds surprised to have made the decision and you hope she follows through with it. You hope she enjoys it when it happens, too, because you desperately want more of this from your wife. You want as much of it as you can get, even if it's dangerous like Emily described. You just can't help it.
