The mango was the best mango Beth had ever tasted. Sweet but not sickly so, and very, very juicy. She’d already finished her bowl, and she eyed the stone left on the cutting board.

Em smirked at her from across the table. “Feeling greedy?” they teased. “Feel free, I’ve had plenty.”

Beth grinned in thanks and grabbed the stone. She nibbled some of the fruit off the stone and nearly moaned. How was it so good? The juice dripped down her arms, and without thinking she lapped it up with her tongue before returning to the remaining fruit. Every bite had her wanting even more, and once she finished off the stone she sucked her fingers one by one, desperate for more of the juice.

As she pulled a finger from her mouth, Beth looked up and realized with a start that Em was standing next to her, looking down at her. Beth flushed in embarrassment — what had gotten into her? — but that was forgotten the moment Em cupped her chin, their thumb resting on her bottom lip, slick with mango juice.

Beth’s eyes fluttered closed and she whimpered, trying to suck on Em’s thumb but unable to maneuver it past her lips.

Em laughed. “You like that?”

Beth nodded emphatically, eyes still closed, mind still focused on the feeling of their thumb on her lips.

“I thought you might. It tastes so good, doesn’t it? It makes you want to lick and suck… Such a good little slut, and all because of a little potion…”

The mention of a potion briefly jarred Beth’s haze. She heard the clink of a stopper being removed from a bottle, but when a sweet liquid dripped onto her lips, her thoughts washed away with the warmth and pleasure. She needed more; it tasted so good, felt so good, and when Em let their thumb slide inside Beth’s mouth she sucked until she reached the first knuckle, her tongue licking further and tasting more delicious nectar on their palm.

Em started to move away, and Beth slid off her chair onto her knees so she could keep sucking on their fingers. Em chucked. At the edge of her awareness, Beth could hear them moving a chair and feel them sitting down, but she didn’t open her eyes; all her focus was on their fingers and that wonderful warming taste. She wasn’t even sure if it tasted like mango anymore, but she needed more, and she settled between Em’s legs happily.

Em carded their other hand through her hair. “You can’t help yourself, can you?”

Beth moaned in agreement, words failing her; but that was okay, her mouth was needed for other things. She rocked her hips slowly, moving one hand down to rub her clit through her leggings.

“Such a greedy slut — who said you could touch yourself?” Em pulled their hand away, and Beth gasped wordlessly, mouth achingly empty. Her hand between her legs went still.

“I supposed I can’t blame you,” said Em kindly. “It’s in your nature. You’re such a slut that you can’t help getting aroused simply eating some fruit, because it makes you long to use your mouth.”

Beth nodded contritely — a part of her thought there was another reason she was acting this way, but she couldn’t remember it anymore, so it must not be important. She was just that much of a slut.

“Really, I should be rewarding you for being a good slut who wants to use her mouth, shouldn’t I?”

Before Beth could find any words to say in response, she heard a zipper opening and that glass bottle clinking. Em then gripped her chin again and guided Beth’s head forward. Her lips came to rest on the tip of their cock, and it was all Beth could do to stop herself from taking it inside her mouth. But Em hadn’t said she could.

“That’s better, isn’t it? A nice cock to suck; I’ll bet it will feel even better in your mouth than a finger.”

Beth shivered in anticipation, her mouth feeling so empty, her tongue longing for more of that sweet liquid. She squirmed between Em’s legs, but she didn’t move her mouth or her hand resting on her clit.

“Oh, I almost forgot.” Em bent down and grabbed that hand. Beth felt something slick flowing onto her fingers. Em then returned the hand to her clit, guiding it under the waistband of Beth’s leggings and underwear. It was so wet and it felt so good, and when Em said, “You may suck my cock and move your hand,” Beth didn’t hesitate.

The taste was incredible; more of that irresistible liquid flowed onto her tongue as she took the head of Em’s cock inside her mouth. Beth hummed with pleasure, tongue darting out for several quick licks before she sealed her lips around the shaft and sucked.

Em’s hand gripped her hair tighter. “Fuck, yes, good little slut, such a good cocksucker.” They guided Beth’s head forward, their cock sliding deeper into her mouth. “Your mouth is made for this, you can’t help wanting to suck - ah!”

Beth did her best to show her agreement with her actions; yes, her mouth was made to suck Em’s cock. She bobbed up and down steadily, hand in her pants rubbing her clit, overcome by the smooth, heavy warmth filling her mouth. Every little moan and gasp from Em urged her on.

It wasn’t long before those noises became louder, more insistent, and then Em gasped, “I’m going to come, I -”

Beth sucked harder, almost pulling the orgasm from Em, and greedily swallowed as her mouth filled with cum. The new taste, Em’s moans, and feeling their cock spasm in her mouth, all combined to push Beth over the edge and she came, still sucking until Em was dry.

Beth woke up on the couch, her head in Em’s lap, and looked around, confused. “Did I fall asleep?”

Em brushed some hair from her face and chuckled. “Yeah, I guess that was some tasty mango.”

A brief memory flashed through her mind and was gone before she could parse it. Beth yawned. Yeah, that mango had been really good.
