The handle rattles...

Suddenly you hear the handle rattle, "Who is it?" Lexi calls out.

"Hey Lexi," Melanie says. You both exchange worried looks "I'm opening the door." You both quickly realize that is easy with the petty lock on the door. "Hold on Diddy! I'm... I'm changing right now..." She hastily grabs a random bikini pair.

"No biggie." replies Melanie but still working the lock. You hastily grab your clothes and jump in her closet. Lexi closes the door as Diddy walks in. You see Lexi begin to somewhat nervously put on the bikini she grabbed. It looks kind of skimpy, but she doesn't seem to notice. "Wow, you look hot today Lex!"

"Oh, thanks, I pampered myself last night." Lexi stammers out. You then notice that there is some cum stuck to some of her hair. It's not huge but still visible.

"You're looking quite flushed, do you feel okay?" Observes Melanie.

"Fine, just a little warm in here." She replies. After what you two were up to, that's not a surprise you think.

Melanie seems shocked for a second and drops her jaw looking at Lexi, "Woah, you're going to wear THAT!?" She indicates Lexi's choice. It barely covers her nipples and has only a triangle of clothe to cover her front. "I never thought you'd brave wearing that!"

"Oh Umm..." Lexi hesitates, "I thought it might help reduce tan lines, and since it's just you girls why not? Right?" she recovers with.

"You know, that's a good idea! I'm going to do the same." Melanie heads to the cloest to find one, but Lexi jumps to stop her. Answering the surprised look, Lexi says "Lemme get that for you..." She cracks the door open more and leans into her closet. You see her heart of hair just above the piece of clothe and rub it, whispering in her ear, "Damn Lex, I think she has a crush on you. What would you think about a three-some babe?" She turns to you and grins. Grabs your cock with one hand gives it a quick two strokes as she exits with the suit. As she turns around she's surprised when Melanie is laying on Lexi's bed, legs hanging off the front and separated a bit. Melanie looks up and smiles, "Like what you see?" You definitely do, especially because beside that is Lexi's ass and just a string down her crack. You resist the temptation to reach out and grab between her ass and pussy.

"Oh, stop Melanie." Lexi states and throws the new bikini at her.

"What's the matter? You usually like when I offer myself up to you." Lexi abruptly stops walking. "I thought you'd like this."

"Why is that?"

"Oh we both really know why you were taking so long."

"You do?" Lexi asks worriedly, glancing at the closet...

"Yeah, you were masturbating. Did you think I didn't notice that you were soaking wet when I came in?"

"Well I thought that..."

"It's okay, I thought you'd want some help out today like you usually do." Damn, is your sister bi too you wonder. You notice Melanie has started to play with herself.

"I'm done, but thanks anyways." Lexi curtly replies and tries t head for the door.

Melanie looks like she has a little purple vibrator she's using on herself. "Oh. Well could you help me out then? I already got myself started thinking about it."

"I don't know Mel, my brother is in the house..."

"Oh come on, I know you imagine him fucking you sometimes when we play around. The risk of him finding out is exciting. Imagine if he caught us." Melanie teases. "If he knew you and your friends loved to lick and finger each other since we don't have time for boys. He'd probably blow a load!" She's right, this is getting good, Melanie is completely blowing all of Lexi's secrets without knowing it. You start to imagine offering your manly services to their little group. "I can't Mel, not with John so close." Just get in your bikini and let's go. She starts walking to the door again.

"Well, I need to get off." Melanie leads, "Mind if I go downstairs and seduce your brother? A big hard cock might be good with how much of a tease you're being." Lexi stops, clearly frustrated. If she's not bluffing, she'll find out you aren't where your supposed to be. But if she gives in she'll be completely admitting what Melanie just said.
