Prompt:
>When she starts to really show, her motherly horse instincts will kick in.
>Moody, bitey, not wanting to be in the spotlight, hungry, swollen teats, random magical discharges. You know, the usual.
 
>swollen teats
>Vinyl will never make you hold her teats for comfort while she performs a show because 'it's your fault that they're like this!'
 
Green:
>Vinyl has you holding her taut bazongas.
>Normally this would prognosticate sexy times, this time however it was an actual necessity.
>Vinyl had recently become preggers and as a result, her boobies had become quite the handful.
>Two very large handfuls at that.
>All that extra weight bouncing between her legs made things like walking rather troublesome as they had grown to such a size that they chafed.
>As you were the culprit for this inconvenience, your sentence was to "keep Vinyl happy".
>This usually resulted in you carrying around the heavier by the day mother-to-be, anywhere she wanted.
>You were also in charge of feeding her, which was already a hard job before she was eating for two.
>As of right now however, you were designated teat holder for the remainder of her show so they didn't slap against her thighs when she danced.
>Damn they've really gotten big and heavy, just a few weeks ago you could hold them steady and have a decent enough gap for her legs.
>Now it was all you could do to keep the hot and sweaty pillows from jiggling too much from her movements.
>It was more effective to hold them up into her body and legs than to keep them separate.
>If they were touching all the time then they couldn't slap and rub now could they?
>This introduced a new problem however, which was every sway and bounce Vinyl did was transferred directly to her mams.
>It wasn't painful for her, quite the opposite, it was turning her on immensely if the drooling and pulsating mess right in front of your face was any indication.
>You could suggest she stop dancing, but that would be like telling a fish to try and stop swimming, it came as natural as breathing to her.
>And besides, it wasn't like you wanted her to stop, you weren't gay after all. The pronounced belly in front of you was evidence of that.
>You decided to indulge her instead.
>Giving her swollen sweaty breasts a squeeze, you could've sworn you heard a moan over the blasting subwoofers.
 
>Additionally, two rapidly hardening objects pressed firmly into your palms and began leaking.
>It seems like it was time to perform another one of your duties.
>Removing your hands, you let Vinyl's engorged crotchboobs fall, dripping with sweat and milk now from the tips.
>Not wanting to leave your mare without support, you lay yourself so your head rested on the pillow for your hands, nestled right between her hanging melons.
>Returning your hands to their job, you navigate one of the pendulously swinging nipples before you into your mouth.
>A tangy taste of sweat is the first thing you notice, followed quickly by a few streams of milk hitting your tongue.
>Mirroring the growth in her breasts, Vinyl's nipples had also followed suit, growing from about thimble sized to over a thumbs width in girth.
>Sucking on the sensitive flesh, you are rewarded immediately with a gush of creamy milk.
>You definitely heard a moan that time.
>Sipping down your treat, the neighboring teat seems to become jealous, squirting a heavier flow as well in sympathy, wetting your face and collar in the process.
>Not wanting the precious liquid to go to waste, you move the other nipple to your mouth as well.
>Getting both barrels was quite the challenge, it was difficult to keep up with the flow with just one, but two was almost impossible.
>It didn't help that Vinyl refused to stop dancing, even changing her movements so that she forced herself down onto you.

>Your hands had been pushed out of the way, making room for the teabagging from Vinyl's tits.
>Without their support, Vinyl's soft flesh was free to slap between each other and her thighs loudly.
>The smell of sweaty mare musk was all consuming as you were force fed beneath her to the beat of her tunes.
>Not one to be outdone, you ramp up your game as well and suck harder on the now even larger engorged nipples in your mouth.
 
>You tugged and nipped the tender buds of flesh, even her areolas puffing up past your lips to receive extra stimulation.
>All this additional attention was making Vinyl go wild, her dancing became erratic and unsynchronized, slamming herself harder into your face with each bounce.
>Her cries of ecstasy were clearly audible above her music now, strangely complimenting the almost equally erratic wubs.
>Not wanting your face to resemble a watermelon on a Gallagher set, you bring out your secret weapon.
>Tracing your hands up her bobbing thighs, you wait for her to thrust down on you and give both of her cheeks a vicious spank.
>A high pitched scream sounds over the crowd, but you are deaf to it, sinking your fingers into Vinyl's expansive plush plot.
>You feel drips on your already soaking chest as you spread your marefriend, revealing her sopping wet sex to open air.
>Exploring her nethers with a few fingers, you find she is easy to slip into with all the lubrication seeping out of her.
>Even though you were holding her still, her insides squeezed and kneaded your hand with vigor.
>Getting into the correct position, you let go of her with your other hand, pinning the first between her sodden cheeks and inside her sweltering snatch, letting her gyrate on top of you once more.
>This also helped her fuck herself with your fingers, her winking clit bouncing off your palm rhythmically.
>Vinyl was going at it with abandon, no longer following the beat, more like a crazed animal trying to get free from a trap.
>Somehow, her milk was coming even heavier now, escaping your mouth and flying all over her crotch, smearing it with a thin white glaze.
>Her insides writhed around your fingers, massaging them so hard they were starting to become sore.
>Then the wild spasming changed into a milking motion, right as the song was nearing its conclusion.
>All of this was too much for the mare, her legs quaking as she came HARD.
>Vinyl pressed her teats as far as she could into your mouth as she let out one more screech of pleasure.
 
>The milking squeezes on your fingers sped up immensely as they were coated in mare love, some of it escaping and covering you below.
>You were pinned under Vinyl as she shook from her orgasm, her breasts and stomach sealing you in a furnace that smelled like a thousand sweaty mares in heat were fucking each other in a hot tub full of milk.
>Vinyl was still cumming, using her legs to squeeze your head even further into her as she rode out the waves of pleasure coursing though her.
>You did as best you could in your cramped position to help her along, working your fingers and mouth on her until she came back down to earth.
>Shakily, Vinyl tries to get off of you but her legs give out, smooshing you one last time into her cleavage before she topples backward on top of your chest, unconscious.
>Your head is finally freed from her milk smelling orgy crotch and notice it was dead quiet.
>Peeking over the turntables you were behind showed that Vinyl's set had come to an end.
>And that a whole crowd of ponies were staring up at the stage, some with mouths gaped and others biting their lips.
>Looks like they got two performances for the price of one.
