You smile at the buff, but smaller fur, a wolf, laying and moaning on the bed, almost unconscious from the stink he just went through. He barely manages to lift his head to look at you, fear filling his eyes as you simply grin back, slowly climbing into the bed on top of him and stradle him, resting your huge bulk on top of him.
"Mmmm, you stink pretty good," you say, grinning widely as you inhale the rank odors you ground into him. "But I bet I can stink you up much, much more."
"P...please, let me go. Please I'm... begging you!" he manages to gasp out weakly, gagging on the vile odor of your body being so close and the rank smell of his own fur after being in your overalls. "You can't do this to me."
"I can do whatever I want. You are my personal stink slave now. So, let's get started, Smelly," you say, sliding a paw under the wolf's head, lifting the other arm and pulling his face right into your rank, smelly, sweaty armpit. Muffled cries erupt from your pit and you grind his muzzle deeper into the rank trap of flesh and matted, sweaty fur. You smear your sweat all over his face, making him smell all the worse, the male fur gagging and sputtering into your pit, squirming underneath you as he tries to get free.
You slowly pulling he coughing face from you pit; he begins gasping for fresh air immediately, and you shove his face into your other, equally rank, sweaty pit, clenching it around his head and grinding it against the sides of his head and muzzle, the stench getting so bad even your eyes water a bit. You drop his head, reeking of your pit, onto the bed as you push away from him. You get up and turn around, aiming your giant, fat ass at him. He stares at you, dazed and confused until you reach back, unbuttoning the butt flap on your overalls, letting it fall back and reveal you vial, rank rear end to him. He screams and pushes at your butt, trying to get out from underneath your body, but you sit back on his chest before he can.
"Oh, you love this, don't you, Smelly," you say, grinning as you wiggle your exposed butt, the stench of your unwashed body, your ass, and your crotch all seeping out of the newly opened hole, mixing into a thick, rank cloud of stink that surrounds the wolf's head, making him gag and his fur wilt.
"Mmm, oh yeah, I could just..." with that your asshole puckers and FFFFRRRRRTTTTTT!! You blast him in the face with a long, thick, greenish-yellow, disgusting fart, the stench immediately filling the entire room as his eyes go wide and he struggles to cover his nose, but your ass sitting on his arms and chest prevents that, and it's all he can do to suffer through the grotesque stench, burning his nostriles with the smell, the yellowish fart hovering around his head as the stench soaks into his fur. "Oooh, that felt good. But now I really need to..."
