"Alright, Doug, you got a whole list of chores there. Ah'll probably catch up with you after a few hours, once Ah finish some of mine and get to apple bucking."

"Sounds good, Applejack, Rainbow; catch you later!"

"Alright, dude, take it easy!"

Applejack and Rainbow Dash watch Doug walk out of the farmhouse, Rainbow waving at the human's back. Applejack glances over at Rainbow, who sheepishly puts her hoof down. The earth pony asks, "So, Rainbow, nice having you over and all, but Ah got a lot of things Ah need to get done around here."

"Oh, hey, that's cool and all." Rainbow's gaze wanders around the room. "I guess I was just hoping that, you know, with heat season starting soon and all..."

Applejack stares blankly at Rainbow as the pegasus makes awkward hoof motions, tapping her two front hooves together before trying to get one of her hind legs in on the action. Applejack sighs, "Just spit it out, Rainbow; what do you want?"

"Pah." Rainbow looks side to side, then out the window to make sure Doug has walked away, then upstairs to confirm that Granny Smith and Big Mac have both already left the farmhouse to work on their own duties. She glances back to Applejack, "Well, I think that my heat has already started, so..."

"And what do you want?"

Rainbow sighs, "Are you really going to make me say it?"

Applejack nods, "Are you really going to make me help out again? If Ah've told you once, Rainbow, Ah've told you a thousand times, if you keep on using a cooler it's just going to make it harder to resist using one the next time. Ah've never used one, never needed it."

"Aww, but you have Doug now! And he's, like, I mean, have you felt his hands?"

"Yes, Rainbow, Ah've felt his hands before."

"He didn't even do anything! He just, like, rubbed my legs and nearly rubbed me out along with them!"

"Oh, come now, Rainbow, he ain't that good with them."

Rainbow starts nodding her head, her pace slowly picking up, "Well, maybe you'll need to wait until you're in heat then, because ohmygosh they felt amazing. Like, I was presenting myself to him after he was done with two legs! Me! And I never present to anypony!"

Applejack looks at the eight inch rubber dong Rainbow had left here the last time, then back at the pegasus. "Ah huh."

"Oh, come on, Applejack, this is different! Please, just the one time. Last time."

"Oh, Rainbow, if only Ah could believe you on that." Applejack stares at Rainbow, the pegasus continuing to give her a pleading look. "Fine. But this is the last time, got it?"

"Sure thing, Applejack, bestest buddy, this is the last time I ask you. Today."

"Right; now, did you-" Applejack turns, glaring at Rainbow, who merely offers a large smile in response. "Fine. Whatever. Here or upstairs?"

"I'll be fast, we can just do it here." Rainbow turns, placing her front hooves on the floor and flicking her tail off to the side. It immediately moves back into its normal position, Rainbow huffing as she flicks it again.

"You could at least wait until Ah'm ready," Applejack quips, filling the pouch. She checks the line to the cooler, giving it a test squirt; it would be a pretty stud-ish move to get Rainbow as riled up as possible, where the cooler would have the most effect once she squirted the solution inside, just for the hose to kink or have a blockage or something, leaving the mare high and dry. Real dry. And mad enough to lash out, probably thinking Applejack did it on purpose.

Rainbow grumbles as she lifts her back end higher, swishing her tail back and forth. Applejack sighs, taking the cooler in one hoof and parting the long hair that covers Rainbow's marehood with the other. A dab of lubricant and the cooler slips right in, Rainbow gritting her teeth at the object penetrating her. Applejack slides it in and out with her hoof, a bored expression on her face as she pointedly looks away from Rainbow.

"So, uh, how does Doug compare to the cooler? Not that I'm, you know, interested in him, of course."

"Well, Ah told you Ah haven't used a cooler before, so Ah can't really tell you. Not that Ah really want to talk about this, either." The cooler slips a little, Rainbow's own lubricant making it a little hard to grip.

"Ah, come on, Applejack, it's not just stallions that talk about this stuff. We're best friends, right?"

"Ah huh."

Rainbow huffs, trying to stand still as the cooler moves in and out of her. "Can't you go, like, any deeper? Or faster?"

"Sorry, Rainbow, but Ah can only hold on to so much of this at once. And it's really slippery, too, once you get going, and Ah'd hate to, heh, lose it inside you. The hose ain't exactly made for pulling it out."

"At least go a little faster."

"Fine." Applejack adjusts her grip, speeding up a little, "You know, you could have just splurged on the twelve inch version."

"Pff, this one has worked fine most times. I just need a more awesome, you know, mental image to work with. So, what's Doug like?"

"Ugh, fine." Applejack slides the cooler all the way out, Rainbow giving a startled yelp and turning to watch. Applejack grunts, pushing the cooler inside herself, giving two thrusts and pulling it out. She pushes it back into Rainbow as she says, "So, he's a bit thicker, and can get about twice as far in, on account of him able to use his whole penis instead of half of this. And he presses all the way up against you, tries to give you the whole thing every time."

"Wait, seriously? There's no way it gets that big."

"Honest Apple, it gets that big. It looks small most of the time but it, like, fills with blood and gets hard, not as hard as a cooler but it feels way better. You can feel it pulse inside you, when he's resting or sometimes when he's thrusting."

Rainbow's eyes go to the ceiling, rolling up into her eyelids as she imagines the cooler thrusting inside her is actually Doug, his hands on her flanks as he pounds her over and over, finally filling her up with-

"Alright Applejack, I'm almost there!"

Applejack moves a hoof to the pouch, watching Rainbow's face. Just before the mare's eyes glaze over Applejack presses down on the pouch, a firm, steady pressure from her hoof that drains the liquid down the tube, through the cooler and into the mare. Rainbow sighs as she orgasms, the solution a brief stopgap for the mare's heat, a bit of the solution and Rainbow's juices spurting out around the edges of the cooler. Applejack withdraws the cooler, a brief look of disgust as the liquid splashes onto her hoof and foreleg. She sighs as she goes to the sink, washing herself and the cooler off before grabbing a towel, looking at the growing puddle underneath Rainbow.

"Thanks, Applejack, you're the best friend a mare could ask for." Rainbow's eyes close halfway, a sultry smile coming over her lips as she moves closer, "And, we could be even better friends if you want..."

Applejack nods her head while rolling her eyes, "Ah huh, that's the cooler talking. Now, if you don't want to leave a bigger mess here, one that Ah will make you clean up, Ah suggest you fly off for a little bit and take a nap or something."

A sleepy Rainbow yawns, "That sounds pretty awesome, Applejack. I'll catch you later!"

Rainbow flies out of the farmhouse, still in a bit of a daze, as Applejack grabs a towel. She cleans up a bit of the fluid that leaked out of Rainbow, a hoof coming to her face as she realizes Rainbow has left the cooler here. Again.
