grunted and throbbed hard, her cock spewing prenut into Arcy's stomach, which already began to bloat from the sheer amount that Windy could output. "Fuck this," she growled, standing up, grabbing Arcy's head and utterly [b]slamming[/b] her head down. Her lips kissed the medial ring, but poor Arcy couldn't take anymore. she could feel precum spurting out her backside in rhythm with Windy's overwhelming throbs, joining her utterly leaking pussy. but she couldn't cum, teetering right on the edge - she would not be able to cum without Master fucking her into the couch. Windrunner gutturally moaned, roughly beginning to facefuck Arcy with no mercy. Her thick cock nerely dislocated the massive mare's jaw, her body just a series of holes for her Master to use, her throat being one of them. She was running out of air, but that was not her primary concern, rather Windy's, the hung mare pulling out just enough occasionally to let Arcy get much-needed breaths of air. Those balls swung under her hooves, flicking musky sweat everywhere and fanning her musk about. The combination of all of these sensations further corrupted Arcy's mind, all thoughts of her previous life melting away. Just Windrunner. Just Master, and her cock. Her life was pleasing her moreso than ever, and that was going to be her life until the day she died. 

"Fuck! Your throat is so tight... Master's going to give you her first load pretty soon!" Her cock flared inside Arcy. Pegasi have brutal flares, and Windy's more than doubles in size, completely blocking any airflow from getting to Arcy's lungs. She's gonna have to ride this one out! Every time that cock bottomed out in her, globs of prespunk would drip out of her aching ponut, her body screaming for more, more, more! "FFuck! Are you ready for my first load, cum dump?"

And then it came with little warning, her cock throbbing so hard even Arcy found herself lifting off the ground onto her tip-hooves occasionally, a fat swell rapidly spewing up her cock before she utterly nutted right into Arcy's stomach. Gallons upon gallons of this impossibly dense, rich, thick, nutritious semen flooded into her, her belly quickly bloating out from the mess. Not a single drop would even get to Arcy's tongue, leaving her wanting more. The worst part? She was unable to orgasm, her body rewiring itself to only cum when Master tells her to. In fact, she was now only able to get pleasure either from Master, or pleasing Master. Guess which one gave her more pleasure?

Oh goodness, she needed air! Her lungs were screaming for it, but her heart was screaming for Windy to give her more, even as that tree trunk slowly ended it's orgasm. Her belly was swelled so much that her hooves weren't on the ground anymore, and that was with a good quarter of that load going to waste out her other end, making a complete mess of the entry hall. Windy huffed and puffed, her balls not shrinking an inch. She would never run out of cum, and if she wanted to pump Arcy forever, she would without even asking. But she didn't want her slut passing out yet! Still spurting her last strands of cum, she quickly withdrew, leaving Arcy room to finally breathe, but also leaving her with a mouthful of cum.

HOLY FUCK. If her prespunk was like pure pleasure, this was the taste of orgasms. It was as thick as tar, superheated (but somehow not burning her) and it was fucking good tasting. It was her nectar and ambrosia, the food served to her by the goddess that was her Master, the perfectly nutritious stuff that would be her only form of sustenance until the day she died. And it affected her too! While she still held those muscles, her belly was absorbing some of the cum, making her ass grow out, become perfectly plush for her Master's pleasure. It was definitely rewiring her entire body to please her, to be the perfect broodmother.

She wouldn't have it any other way.
