Something seems fishy about Stacy

Stacy gazes steadily into her sister's eyes as she teases, "I see you're into boys AND girls..." she says as she nods her head to you and then Amina. Her gaze doesn't break and she rubs her sister's legs over the sheets. "Why not try it with someone you're really close to? I've watched you with guys, you know... I know what you like..."

Stacy slides her hand underneath the sheet and despite Melanie's protests, the elder sister merely watches with paralyzed shock as the cheerleader finds her foot and begins to rub it. Melanie moans softly and pleads, "Don't... that's not fair..." Her eyes melt with her resolve as Stacy pulls her sister's foot out from under the covers and sticks the big toe into her mouth. Melanie closes her eyes and gasps, "This isn't right!"

Stacy's eyes go wide as she makes a big grin, saying, "It feels so wrong, but that's what makes it feel so good, isn't it?" She runs her tongue along the sole of Melanie's foot, sending her sister quivering with deviant pleasure.

Melanie can't help but clutch at herself through her bed sheet. Stacy licks and kisses the girl's foot like it's ice cream. Melanie leans back as if trying to move away while also lifting her leg higher toward her sibling. She continues to reason with her sex starved sister. "There are people watching... what would mom and dad say?!"

You are indeed watching as is Amina and Lynn. Neither of them make a move to interrupt, but you have a growing suspicion that there is something odd about Stacy's behavior even beyond what Lynn claims to be a power trip from having access to her wishes. She is using some sort of magic on her and there must be a way to prove it.

Stacy shrugs off the observations her sister had just made by saying, "You should have seen what Lynn and I were up to earlier! She can just make everyone but us forget, so we can get away with anything!" In order to prove her point, she also shrugs off her shirt and pulls off her pants and underwear. She sits on her knees, completely nude and smiles at her dumbfounded sister. "We can do anything we want and no one will know about it!" Stacy sits back and spreads her legs, openly masturbating for Melanie now. She lets out a sultry moan and murmurs huskily, "I don't even mind the audience. Makes the **** so much more dirtier... So what do you say? Let's fuck!"

Melanie looks like she's about to give in to this depraved offer. Her eyes are firmly on her sister's body as she swallows dryly. If you're going to save her from this taboo, you better act now.
