    Chapter List

    “I don’t want to go home! I want to stay here with you! I want to keep fucking!” Somi cries as she holds onto your leg. Her phone buzzes again, another message.

    “I can’t wait, honey. I’ll have a different position when I get back. I won’t need to travel so much, and I can finally spend time at home.” You both see the message from her husband.

    “He’ll be back and spending more time at home. Even if I wanted to, there would be no chance."

    "I-I… no.” Somi shakes her head violently. She runs her hand through her hair, ruffling it. Her breathing quickens, “I-”

    “No more of this, Somi. Go home. He’ll be waiting for you.” You get up and toss Somi a jacket. “I’ll take you there.” Somi sits on the floor, unmoving. Through many struggles, you put Somi in her clothes and get her to her home. She doesn’t move or make a sound. Walking over to her side of the car, you open the door and carry her inside. You leave her on a couch and bring in her things, clothes, toys, and everything that she had brought to your place. She sits on the sofa, head buried in her hands as you leave. The drive back home is quiet and peaceful.

    The following day, you wake up to a load of videos and pictures from Somi. Each one involves her doing some lewd act and begging you to continue the relationship. In one, she’s bouncing on a dildo with her legs spread wide open, letting you see her dripping sex as she wishes it were your cock. In another, she’s forcing a toy down her throat, her throat bulging when she pushes it in deep. Somi looks into the camera with lustful eyes in each video. As for the pictures, the final one she sends is of her with self-degrading words written on her naked body, “master’s pussy” with an arrow pointing to her cunt, and the like is written everywhere. A constant throughout everything is the collar she wears. The collar symbolized her submission to you; it was bought for that specific purpose. “Master, your fucktoy needs you. These toys aren’t enough for me; I need your big, hard cock.” She sends in her final message. You ignore her, putting your phone back down.

    When Somi’s husband arrived, she made it seem as if everything was normal. However, Somi would send you videos where she’d have a vibrator inside her, explaining that she was hiding everything from her husband. She would still wear the collar, though. You don’t know what he thought when he saw Somi wearing such a collar. One day, you received a message from him asking you to join them for dinner. You tried to refuse but were forced into it in the end. When the day came for this meal, you tried to keep things professional. “It’s nice to have you back.”

    “It’s nice to be back. I’m glad I managed to finish early; I was missing Somi.” He responds.

    “Where is she, by the way? I haven’t seen her."

    "Oh, she’s cooking.” Somi pokes her head out and smiles at you, still wearing that collar. As you turn your head back, you see him rubbing the back of his neck. “Um, you may have noticed that collar. I’m not sure what’s come over her. She refuses to take it off.”

    “Yeah, it’s something alright.” You reply, trying to figure out how to continue.

    He leans in and whispers, “Between you and me, she’s also been craving sex at every moment. I can’t do it anymore, so I thought inviting you might give me a break.”

    “Well, you know, you’ve been gone for so long. She's… probably pent up.” You say that, knowing fully why she is the way she is.

    “Dinner’s ready!” Somi shouts from the kitchen. She brings out plate after plate of food. You both go to help her, and while her husband goes to place a plate on the table, Somi kisses your cheek. “Master, I’ve tried filling the void, but he’s not enough. He doesn’t- can’t fuck me like you can.” She whines quietly into your ear. “Master, your fucktoy needs her owner to use her,” Somi adds before returning to the dining room. You follow quickly, placing the final plate on the table. Taking your seat, you’re annoyed that Somi is sitting opposite you while her husband sits to your right. As you all begin eating and talking, Somi can’t help but rub your crotch with her foot. You don’t react and push her foot away. Somi frowns for a second before trying to hide her expression.

    “So, how was the trip?” You ask.

    “Oh, you know, business is business. I was missing Somi the entire time, though. Did you miss me, Somi?” She fakes a smile and nods without saying a word. She stuffs her face so that she wouldn’t have to speak. “I’m just glad to have a different position now; I can stay here and not leave her alone so often.” You glance at Somi and see her roll her eyes as her husband continues talking. The meal went like this for a long time; her husband drank a lot of alcohol and got drunk. “Did I tell you about how we’ve been having sex nonstop?” He boasts. “You should hear her.” He says before leaning in for a kiss from her. Somi looked as if she was going to boil over in anger. You watched on awkwardly.

    Somi stands up and slaps her husband. “You can’t make me feel anything!” She yells. “Anytime we’ve had sex, I’ve faked it! I faked everything! Every moan, every orgasm, everything!” Somi’s husband looks at her with a shocked expression. “Your little shrimp dick can’t make me feel anything! I need a real cock…. I…I want a divorce. I can’t do this anymore.” Somi glances at you before storming off.

    You and her husband sit there in silence before you eventually stand. “I think I should go. You two seem to, uh, need space.” You nod your head at him before leaving him to sit there. Soon after you arrive home, there’s a knock at the door. Checking through the peephole, you see Somi, much like the first time she came to you.

    “Master, your fucktoy is ready for you.” She says as she opens her jacket. Words like bitch and whore are scribbled on her body, “Do you like what you see, Master? I brought my toys too.” She says, stepping to the side to reveal a suitcase. Somi knocks again, “Master? I know you’re in there. I saw your car.” You open the door.

    “What are you doing here, Somi?”

    “I can’t stay at that place anymore. I’m divorcing him after all. So now we can be together. We can go back to how things were before. We can have all the sex we want.” Somi says matter-of-factly. She steps toward you, pressing her breasts against you. “ She stands on her tippy toes and whispers, "You can do anything you want to me, Master. You can even get me pregnant. Can you imagine that? Me with a big, swollen belly, but you can still fuck me then if you want. We don’t have to worry about anyone being involved anymore."

    You step aside and allow Somi inside. "Would you mind explaining why you did what you did?"

    "I couldn’t stay there anymore. I tried having sex with him, but he couldn’t make me cum. He’d be done, and I got nothing out of it.” Somi throws off her jacket and kneels. She gazes up toward you and opens her mouth. Waiting for you to use her, she sticks her tongue out and kneads her breasts. The sight before you makes you hard, and as much as you want to ignore her actions, you decide not to. You pull down your pants and ram your cock down her throat.

    Somi happily accepts it, placing her hands on your thighs as you thrust. “You’re just a stupid little whore aren’t you?” Somi smiles and nods as best as she can. The cock going up and down her throat doesn’t give her the ability to speak. The look on Somi’s face is one of pure bliss as her tongue runs along the underside of your cock. Holding her to the base of your cock you feel Somi’s tongue slither to your balls, lapping at them before you thrust again. Somi moaned; she rubbed her cunt while you used her warm mouth. Her lips were tightly wrapped around your cock, but that didn’t stop drool from dripping down her chin onto her tits. She giggles as you reach down and starts playing with them.

    You slowly drag your cock out of her mouth, leaving it at her lips for a second. Somi knows what you want and kisses the head of your cock. “If you want my tits so badly, then why don’t you use them?” Somi kneads her breasts, pinching her nipples while waiting. Placing your cock between Somi’s tits, you feel the soft flesh surrounding your shaft as she begins stroking your cock with them. “I love your cock.” Somi whispers as the warm member slides between her tits, coating them in saliva and precum. “Master’s cock is the best.” Somi stares at your cock before glancing at you. “Do you like watching your dumb whore use her tits?” She asks, almost innocently.

    “Of course,” you reply as you push her head down and make her take licks at the head of your cock when it pokes up from her mounds. You start thrusting between Somi’s big tits when you feel your orgasm coming. Somi can tell you’re close, too; the throbbing cock between her breasts tells her as much.

    “Are you going to cum?” She asks. When you nod your head, she continues, “Cum on my tits, Master!” You explode on her chest, releasing a large wave of semen onto her chest and neck. You pull on her collar, ensuring she gets a pearl necklace.

    Pulling on Somi’s collar, you get her to her feet. You drag her along to the kitchen, where you bend her over the counter. A hard strike to her ass makes her yelp. You hit her again; Somi’s ass slowly becomes red with a large handprint in the middle. “That’s it, Master, show your whore who’s boss.” Somi moans as you spank her again. You press your cock against her cunt, waiting for a second before you impale Somi with it. “Oh fuck!” She cries, and she feels you tear through her pussy. “I feel so full, fuck me, Master. Fuck me!” You hold Somi in place as you start thrusting; her tight cunt holds you as your bodies slam against each other. Long breathy moans fill the space as Somi enjoys the feeling of your cock slamming into her womb. Letting go of her waist, you move your hands to her breasts, pinching and pulling her nipples.

    “I’m going to cum inside you.” You say to Somi.

    “Cum inside me, cum inside me!” She moans. “I want you to fill me with your hot cum!” Somi places her hands over yours and squeezes her tits. Being brought so close to her climax, Somi’s toes curl as you impale her on your cock and begin filling her with your cum. She screams; the few days of having no orgasms are over. Somi’s nectar blasts out onto the cabinets under her as she climaxes. Your cum paints her walls white as they travel to her womb. “Oh god. I feel so full. So full of nice warm cum.” Somi lays her head against the cold marble countertop and smiles. “You definitely knocked me up.” You lean back and spank Somi. “Oh, Daddy, not so rough on Mommy,” Somi coos. You pull your cock out of Somi and watch cum leak onto the floor. Somi’s feet reach the ground, and she kneels before you again. “Are we done, Daddy? Or is this just round one?” Somi takes your shaft in her hand and strokes your cock, her hand is dirtied by the cum and nectar on it, but that doesn’t bother her. She drags the tip of her tongue along your shaft before popping the tip in her mouth and sucking on it. You push your cock in deeper, causing Somi to laugh. “I knew that was just round one.” She says, mumbling her words. You continued to fill Somi’s holes with your cum the rest of the day.

    Somi had gone back to wearing nothing while living with you. You tried to get her to live elsewhere, but it didn’t work out. She’d just be your live-in fucktoy for now. She’d occasionally get messages from her husband, hoping they could repair their relationship. That didn’t work out, either. After he had figured out that Somi was living with you, he came to try to talk. Having happened to just gotten home, you were both fully dressed; answering the door, Somi stood there, surprised. He was in shock, too. Shocked to see his ex’s belly swollen with a child. He fell to his knees, and Somi stared at him before shutting the door in his face without a word being said.
