Clop or not, this is good.

She wouldn't mind if it was just her, but it would probably made Big Mac look bad if she showed up a ruffled, sweaty mess.

^make

She didn't jump into relationships, especially when she could be patient enough to wait.

^this should be rephrased. like, "she didn't jump into relationships; she could muster the patience to wait."

The blue mare said, picking up the other mare and dusting her off.

^this sentence has the word mare two times. Also, LUS.

"I'm in the same situation anyway."

^the 'anyway' is not really needed, also, this eludes to the start of a conversation, but it actually doesn't, so really, this entire line of dialogue is not needed.
Also, a persistent mistake you have in the entire story is the fact that you do not put a comma after dialogue. When you have a line of dialogue which ends with any variation of "she said" there needs to be a comma. The only time there would be a period is if the dialogue is followed by an action. So like "Blah blah blah." She rolled her eyes. "I can do what I want." is perfectly fine.

"You been waiting long?" She asked, staying a couple feet from his face so that she didn't have to crane her neck too much.

^huh?

He replied, in his usual southern drawl. Short, as usual.

^none of this is really needed. 'He replied' is enough. Everything else is over stating what we already know, and frankly uses the word 'usual' way too much.
That's all I have, really. Actually, it's not, there are a lot more mistakes in this piece of writing, such as your need to have words like 'inquired' or 'queried' when you can just say 'asked'. Granted, you didn't really use them too much, but regardless.
This is not bad , though the constant grammatical mistakes make it painful to read. That, and I'm not the biggest fan of MacDash.

not bad not bad at all. *slow claps*

Alright you got my attention. I'm sort of wondering where the fetish stuff is going to kick in and interact with a story that's this vanilla so far. I enjoyed the interaction between Dash and Mac in this chapter, though I thought Dash would be just a little bit excited about the prospect of more cider.

I wish that there was some kind of filter for just clop, as I have no interest in that but there are several good mature stories without it, but don't like having the page hogged with suggestions for porn

Futa Mac? Take the emoticons of my expectation of Dashie on learning it.

Wat...
Is Mac good for both, or just the stallion parts?
It don't matter, I GOT MAC!!!
Now to claim him first...

This is superb! More, please!

WHOO! God, I love this shipping!
A'ight, let's do this

Came for the MacDash. Doing pretty good so far.

"Ah'll take the soup of the day with extra avocado, that little shrimp appetizer, the house salad, and the Straw Hat." He said, handing the waiter his menu.

Anyone else see that capitalized Straw Hat and think 'The Luffy Special'?
