Friends with benefits

Cherry Berry trembled, legs almost knocking together with the force of her anxiety. The human stood before her in her home, calm and unhurried. Ever since the union of the two worlds, she - like so many other ponies - had heard such amazing things about their newest neighbors. Wonderful, exotic, otherwordly tales of what human beings were capable of, the wonders they could produce, the gifts they were so very willing to share. It hadn't taken many such stories of utterly satisfied, blissful mares before the pony's reluctance had crumbled like so many before her. She needed to experience it for herself. Muscles tense with anticipation, she had awaited his arrival as though she would bolt at the first sudden movement. When he had entered her humble home, her throat immediately went dry. And now, much later, they had come to the climactic moment. It was time. This was it.

The human spoke, his voice a deep baritone. "All set. Are you ready, miss?"

She swallowed hard. "I'm... I'm ready. I think... I think I'm ready."

He smiled reassuringly. "No need to be nervous. I do this all the time. Getting used to the way you ponies do things took a while, but it almost always goes smoothly now."

She tried to return his smile, still nervous but feeling somewhat better all the same. "It's okay. Really, I'm ready. Let's do this."

He nodded. And then, he flicked the switch.

For a moment, nothing happened. And then, it began; almost imperceptible at first, but rapidly growing in intensity. Cherry Berry shivered, a thrill shooting through her at her long-awaited prize. "Oh, Celestia, YES!"

The human chuckled. "I take it you approve?"

She nodded, eyes closed as she basked in the sensations. Oh, when she'd first heard of the humans, she had her doubts, just like so many others. But even just for this, they were so very, very, VERY worth it. "It's everything I ever dreamed of..."

The human broke into a grin at the pony's ecstatic reactions. Most of them reacted in just this way, and he never got tired of seeing it. "Well, there's plenty more were that came from. You can control and set it any way you like from this panel on the wall, here. You have any trouble, you give me a call, alright?"

Cherry Berry nodded absently, still groaning in fulfillment, her face inches away from the vent in the wall. Luna bless humans, and Celestia bless their wonderful, wonderful central air conditioning.
