An intruder appears

"I want to." Lilian explained, interlocking her fingers with Riley's.

"But?" Riley purred.

"I... I wouldn't know how. Before today I didn't even know you could feel this goo." Lilian shyly admitted.

"You never even masturbated? Touched yourself down here?" Riley asked as she ran her hand over Lilian's exposed pussy.

"My parents told me my skin would fall of if I rubbed any one spot to long. It was only a few years back that my brother told me how ridiculous that sounded." She frowned thinking back on the memory. "They admitted it was lie to get me to stop rubbing my rashes, but I guess the psychological effect stayed with me."

"Man they really did a number on you." Riley said. "Well luckily I'm an excellent teacher! Just ask Ryan."

Ryan crawled out from under Riley's skirt, rubbing his jaw as he moved up to lie down next to them.

"Don't listen to everything she says Lilian." He told her, still massaging his jaw. "Her 'teaching' method is just to moan and beg you not to stop."

"You can't criticise me when it works." She joked, before moving up to Lilian's ear and whispering into it.

Lilian blushed a little hearing her suggestion, but nodded to it all the same. She rolled off of Riley pushing her body against Ryan's. He wasn't was warm or soft as his sister was, but she still felt a rush as embraced him.

Without giving him time to react she wrapped her lips around his, kissing a boy for the first time in her life. He was much more passive than Riley had been, making Lilian dive her tongue into his mouth to get what she was after.

"Do you like that taste little Doe?" Riley asked softly. "That's me you're tasting on his tongue. Now get down there and have the real thing."

As sweet as Riley had been, she could certainly sound demanding when she wanted to. Lilian wasted no time breaking off her kiss and making her way between Riley's legs. It was dark underneath her skirt in the already dim library, but Lilian was still able to make out her shape.

She was recently shaved, with a small about of dark stubble growing back in. Lilian hadn't ever considered shaving her hair like that, but seeing Riley now she understood the appeal.

"Just start slow, explore a little." Riley told her. "I'm already pretty close so you get to decide when you want me to cum."

Lilian carefully gave her a gentle lick, taking the fresh taste into her mouth as she steeled her nerves. She placed her mouth over Riley's pussy, kissing it like she would her mouth. Her tongue ran across and into Riley with easy, as she was already dripping a sweet wetness.

While Lilian linked her in a similar way to kissing, the results were completely different. With ever move, every flicker if her tongue she would feel Riley twitch or moan in reaction. She knew how good those boys had made her feel doing this and knowing she could give the same to Riley made her heart dance in her chest.

Just was she was beginning to find a rhythm, find the spots that made Riley clench the hardest, she heard an unfamiliar voice coming from behind her.

"Who's this whore you've found Riley? She's not you're cousin or something is she?" The intruder asked, malice obvious in her voice.

Lilian realised how ridiculous she must look. With her head down Riley's skirt she had her butt sticking up in the air. Whoever this person was they would have a full view of Lilian's exposed ass under her tiny shred of a skirt.

"The fuck are you doing here Vicks." Riley said, putting emphasis on her name.

Lilian tried to move from the awkward position she was in but Riley clamped her thighs around her neck as she tired. She was surprisingly strong and Lilian's futile attempts to get free only made her wiggle her butt in front of this stranger.

"Settle down freak, I just needed to talk to you where nobody important would see." The girl said, tracing her hands across "God you just attract the weirdest people these days, who even writes 'Slap me' over their ass"

What was written on my ass. Lilian thought to herself before she felt a sharp pain from being slapped multiple times I quick succession.

"Don't stop just because me Ex is watching Lilian. I won't br able to endure this conversation otherwise." Riley commanded her.

"Stop calling me your Ex." The girl said, taking out her frustration on Lilian's ass. "Just because we messed around a few times, does NOT mean we dated."

Lilian was still reeling from the pain, for a girl with such slender fingers her slaps hit harder than any of the boys did. Still she didn't want to disappoint Riley and began lapping up her pussy again.

"Mmmhhh, yeah whatever. Just tell me what you want Victoria, so I can cum already." Riley moaned out, her fingers digging into Lilian's back.

"I need weed for tonight." Victoria said, getting down to business. "Do you have enough on hand to cover my friend's too?

"Ohh fuck keep hitting that spot!" Riley cried out, ignoring Victoria.

"Quit playing with your toy and pay attention to me!" Victoria demanded.

Lilian didn't like being between the two girls. Especially when one was beginning to restrict her breathing with her thighs, and the other was periodically slapping her ass red.

"Ohh God! Fuck, yes I have enough! Just, mmmhhh don't funking stop! YESSS!" She dug her fingers deep into Lilian's back as she began convulsing against her with pleasure. Lilian didn't want to disappoint so she tried her best to keep licking as she felt Riley clamp around her tongue.

"Okay.... okay you can stop now." Riley told her between breaths as she released her.

Crawling out of the skirt Lilian was able to get a look at the new girl. She was a thin, athletic, blonde, who perfectly fit the stereotype of cheerleader that her uniform marked her as. The blonde looked down at Lilian with disgust, as she quietly crawled over to the corner Ryan was cowering in.

"Jesus christ." Victoria brought her hand to her forehead. "I'll pay and pick it up at you're tonight, like normal ok?"

"Sure thing." Riley said, still beaming from her post orgasm bliss. "But you know if you want to save some money, I'll always accept other payments..."

"Fuck you, freak." Victoria said plainly, walking off into the bookshelves without giving them any sort if goodbye.

"Sorry she ruined your first time." Riley said as she picked herself off the floor. "She used to be cool before she reinvented herself as the God of cheerleaders."

She extended a hand to help Lilian up, pulling her close into another kiss as she lifted her.

"Mmm you've got a real talent either that tongue you know." Riley giggled as she talked. "I haven't cum that hard in months."

"I'm right here." Ryan said dryly, still sitting on the beanbag.

"You know I love how you make me feel." She reassured him. "But girls just know how girls like it."

"Thanks, I'm glad I could make you feel good." Lilian told her. "And I'd be happy to try and make Ryan feel good to!"

"I think there'll be plenty of time for that." Riley said. " But first we should probably get you cleaned up a little, maybe find a shower?"
