WIP
"Ugh. Fuck!" Dash complains, slamming the door behind her. She's already laid out on the couch when you hurry out from the kitchen in your apron, her hair messily strewn about as she reclines. She looks up when you walk in and points between her legs.
 
"Sit on it," she growls.
 
You know better than to refuse when she's in a foul mood, and the best way to cheer her up is to let her pound you balls-deep until her frustrations vanish anyway. Not to mention, you think as you watch her equine cock swell with blood until it's as thick as your arm, you secretly love it when she treats you like this. Your dick is already tenting your maid's outfit, but Dash pays it no mind. As your master, she doesn't ever let you fuck her or get you off herself. You secretly love that too. That's the way it should be.
 
Wrapping your fingers around her flare, you carefully align it with your ass and begin a slow, controlled descent down her bloated rod. You can't help but gasp with pleasure as she slips inside, the head of her prick rubbing across your prostate and sending a shiver down your spine. Dash doesn't care about waiting for your shaking to subside, though. You feel her hands roughly seize you around your hips.
 
"Down, slut," she says cruelly, pulling you gasping and moaning down the rest of her length until her balls are flush against your buttocks. It hurts, but the pain is far outweighed by the thrill of pleasure you get obeying her words. You can't help but be elated when you feel yourself sitting in your mistress' lap, feeling a little proud that you can take all of her. Dash doesn't give you long to celebrate, though.
 
"Bounce on it, you dumb bitch," she murmurs, reaching under your apron to grab and twist your nipples as incentive.
 
"A-ah!" you moan helplessly, trying to raise your hips before Dash snorts in frustration.
 
"Fuck it, I'll get you started," she grunts.
 
She puts her hands back around your hips and pulls you up, gyrating her hips before driving her cock up into your guts. A loud smack echoes through the room as her plump balls slap against your ass, your cry of surprise quickly subdued by the next thrust. Soon enough the overbearing mare has you moaning like a whore, putty in her hands while she uses you for pleasure. She gives you a good fucking before taking her hands away, giving you freedom of movement.
 
"Your turn, Anon."
 
Dash spreads her arms along the back of the couch and lays her head back as you begin bouncing in her lap, your unresisting asshole swallowing her to the hilt, befitting of the well-trained slut she's made out of you. She was always upfront about who would be wearing the pants in the relationship, but as time has gone on your roles have become more and more defined. She runs the house. You're the stress relief, maid, and cumdump. Your sleep is interrupted every morning by Dash humping your face until she blows a fat load of spunk right down your throat, then you spend the rest of the day cleaning, cooking, and fantasizing about what she'll do to you when she gets home from work. All in all, it's a pretty great arrangement.
 
"Harder," she grunts, interrupting your lusty reverie.
 
The room is silent save for the smack of flesh on flesh as you obediently bounce in her lap as hard as you can, her cock swelling in size until you can barely get past her medial ring. Knowing she's about to cum, you squeeze down on her hard as you slide. A curse uttered through gritted teeth is all the warning you get before she wraps an arm around your stomach and brutally pulls you down her entire length, frantically bucking her hips as she peaks.
 
She groans in orgasmic bliss as you feel the first spout of her jizz splatter into your intestines, Dash holding you tightly to ensure you take every drop of spunk she has to give. Her balls churn and pump from underneath you, dumping barrelful after barrelful of mareseed into your guts. She continues moaning all the while, her hips giving erratic little jerks every time you feel another spurt of warm, virile semen into your depths. Finally, she sighs and leans back, luxuriating in post-orgasmic warmth while she watches your insensate form.
 
"Hell if you aren't a good cumdump, Anon. Look at this," Dash jeers, reaching around to prod your cum-swollen tummy. "Anyone'd think I got you pregnant, seeing your dumb ass like this."
 
All you can do is moan in reply as she hums happily, apparently content to let you sit in her lap like some kind of sex-trophy struck dumb by torpor. Above all else, though, one sensation rises to the top of your mind: she's still rock-hard inside you. You slowly look down to see that her flare, despite being surrounded by cum, is still imprinted on your stomach.
 
"You like that?" she whispers from behind you, her head on your shoulder. "Seeing how deep you can take it? I do. It makes me horny as fuck, seeing you whimpering and moaning like a two-bit slut on the end of my cock." She leans back. "Now get up."
 
Moaning lethargically, you struggle to your feet with Dash's cock still inside you and try to loosen up to let her out, but the next thing you know your voice has risen 2 octaves as she stands up too. She speaks from right behind you.
 
"Walk," she murmurs, her prick keeping you on your tiptoes. "Kitchen."
 
With every hesitant step you take, Dash rears back and bucks her hips into you, her still-heavy balls slapping off your backside. She laughs at your reactions, reaching up and pulling your hair until you're bent backwards looking at her.
 
"Keep walking, slut," she says, her smile reaching her ears. "You're so close!"
 
You can hardly keep your eyes from rolling back into your head while she fucks you, and when you finally reach the kitchen counter you collapse on top of it, your dick bouncing uselessly as you cum all over the inside of your outfit.
 
"You made it, even if you look pretty pathetic right now," Dash congratulates you, pulling your arms up and behind you, holding them down across your upper back. "Now hold still. You're not fucking going anywhere until I've cum at least five more times."
 
She slaps you across the ass, leaving you with a red welt and a stinging sensation
