(I decided to make this humanized)

Fortunately, both Big Mac and Beau had kept it to just kissing and had fallen asleep in each other's arms...

The next morning, Beau woke Big Mac up by slowly kissing along his chest.

Big Mac woke up to Beau's gentle kisses and slowly stroked his mane... he gently caressed his ear...

Beau's sweet spot...

Beau nuzzled into Big Mac's broad chest..

They couldn't be happier...

"I love you" said Beau.

"I love you too" said Big Mac.

Beau poked Big Mac with his horn... For the strangest reason, Big Mac liked it.

Beau got out of the bed.

"Where you going?" Big Mac asked.

"To take a leak" said Beau. He went to the bathroom and closed the door. Moments later, there was a sound similar to a waterfall...

Just then, there was a knock at the door. Big Mac got out of bed, walked to the door and opened it.

It was Applejack. She froze. "B-big Mac? What in tarnation are you doing here?"

Big Mac sighed and said, "Uh... Um..."

"Why are you naked?" Applejack demanded, "Put that thing away!"

Big Mac just glared at AJ. He said, "Well what the buck are you doing here?"

Just then, Beau came to the door and peeked over Big Mac's shoulder. "Hi AJ. What brings you here?"

"I could ask you the same thing" said Applejack.

"I live here" said Beau, "This is my house. Oh, Big Mac and I have some big news. We're in love."
