''Haa...hahh...oh wow..." Twilight panted, finally coming down from the unreal orgasm she'd just had. Her skirt was hiked up and Barb was sitting nearby, licking the last bit of something off her lips. "That was...I..." Twilight flushed when her head began clearing. "B-BARB, the heck??" She squawked, looking at her assistant/oldest friend/unoffical little sister in a mix of shock and confusion. "You just...me...tongue...eep!" She blushed even harder as it sunk in.

"Twilight, calm down." Barb replied. "I'll explain as soon as you settle, all right?" She waited as the mare did her 'cool down' breathing exercise, finally relaxing a little. "You ok now?"

"I think so, just..." She gestured from her, to Barb, then to her still exposed mound. "When do you...??"

"Twi, I'm Bi."

"...come again?"

"I like stallions and mares." She smirked at the squeak Twilight let out. "I have no problem with the idea of going down on either."

It took Twilight a moment to say anything really articulate. "Huh...didn't know that...guess that explains a couple things, but..."

Barb's smirk turned into something Twilight couldn't quite describe, except it was making her sex quiver a little. "Well, since everyone's feeling pretty crappy from this weather right now, I thought I'd smack two birds with one shoe. You, Twilight Sparkle, were customer number one in a little...I guess you could say business, but service sounds better."

"You...you're wha?" Twilight's jaw slackened slightly.

"To put it bluntly, I love oral." She started slowly moving closer to Twilight. "Mostly giving it. I love how a mare's pussy tastes, how they feel in my mouth, the way they squirm and moan while I'm between their legs..." By then, their noses were almost touching, and she was once against positioned between her 'sister's thighs. "Granted, I haven't given a blowjob yet, but...I've practice a little. Anyway, I figured 'why not help take everyone's mind off the heat, and I get to indulge myself. It's a win-win."

Twilight gulped. She had not expected to be encountering this today, or at all. Especially from Barb of all people! Admittedly, Barb was old enough to make a choice like that, but she had reservations about the whole thing. "Are you sure about this Barb?" She asked. "I mean, if word gets out, you may attract some unwanted....'customers'"

"And to them, I say 'I reserve the right to refuse service." Her grin widened. "As for being sure...your brother's birthday is in a week, isn't it? You think Cadance would be cool with him getting my first suck?" Her tongue snaked out to its full length. "I can already picture how he'll taste when I wrap around that fat-"

"Tmi! TMI TMI!" Twilight flailed. "Do NOT need to have that image in my head!" She shuddered slightly. "Ok, ok. I'll go along with it...just one thing."

"Yeah?"

Her cheeks pinked as she bit her lip. "Um...is...it just one to a customer? I need something to get that out of myyyyyhhaaa..." She fell back against her seat when Barb slid down and she felt the dragon's tongue snake back over her pussy.

All right, my pretties, who should be Barb's next 'customer'? Male or Female.
