Elias should have a little dog bed under his desk for Jon.
At first Jon refused to use it. It was humiliating. Degrading. Did Elias seriously expect him to- to sit in that?? Wouldn’t cockwarm Elias under his desk anymore, which did almost win Elias back over, but he knew Jon’s bark was stronger than his bite. He would cave.
And he did. Slowly at first. On those days where all he wanted was to hold Elias’ cock in his mouth, receive his warm, soft affection, that gentle touch on his hair, where nothing was expected of him but this. And so he would reluctantly slip to his knees and crawl backwards onto the dog bed. And Elias would tilt Jon’s head back and call him “good boy” while unzipping his trousers, and Jon would ignore how it made him shiver. How kneeling for Elias in his little dog bed made him wet.
He’d start to fantasize about it. Elias bringing the dog bed out from under the desk. Keeping Jon on it (leashed and collared, of course), making Jon suck him off while anyone who wanted could just come in and See. Jon whining for his owner’s cock while some donor or employee watched him hump Elias’ leg like a dog in heat. Ashamed of how hard the idea always makes him cum.
And then it escalates. Elias getting Jon a dog toy, something nice and big enough to hump. “I can’t have you making a mess of my shoes, Jon. And we both know how you are when it comes to self control.” Pressing it against Jon’s cunt and smirking when he gasps and shudders at the spark of pleasure and heat it ignites. Jon warming Elias’ cock again. Sleepy and aroused, going to rut against Elias’ thigh until he pulls out and moves it away. “No Jon, we talked about this. Don’t you want to be a good boy for me?” Letting Jon continue until the moment he tries to bring himself off on Elias, until Jon is desperate and whining and begging for touch. Kicking the dog toy over to him. Not letting him take Elias’ cock back into his mouth until he begins to hump it. Helplessly rolling his hips down onto it again and again until he cums, gasping and swallowing around Elias’ hardening cock.
Jon thinks about curling up in his little dog bed often. The softness, the comfort, everything falling away except for being a good boy (a good dog, Elias’ good dog). Soon Elias buys him more dog toys. Things for him to suck and chew on when Elias is spent and Jon is still feeling restless. Gets him a collar and a leash. Maybe even sends him a dog bed for use at home, when he doesn’t have Elias to comfort and care for him like he needs.
Perhaps he even gets some newspapers, puppy pads (or whatever they’re called) to make Jon use while he’s being Elias’ dog. At first Jon refuses to use them, tries to hold it till the end of the scene, but he can never last long enough. Letting out a sad little whine as he wets himself, pee flooding his trousers and soaking the dog bed. Until, of course, he gives in. Shamefully pulls off his pants and underwear and squats to piss where he’s supposed to, like a good dog.
Always, Jon pushes back, loudly resisting every gift and gesture and request until his own need and desire wins out and he gives in. Submits to Elias and lets himself be a good boy, just like he needs.
