You're not quite sure if you understand what she's saying. "Does she really not know what I was doing?" you wonder.
"Well, did you." she laughs again.
"I didn't mean to. Fuck, I... wha'..." you begin explaining, realizing that your gorgeous virginal dumb-as-a-stump sister thinks you were blowing your nose in her luscious twat-juiced knickers.
"You thought they were a hankie." and she once again giggles, "I wore them all day yesterday and all night. I just took them off like ten minutes ago."
You cock had been subsiding, but hardens again at the thought of their freshness.
"Language, please" Marissa corrects, covering her ears dramatically in response to the defiling f-word that spewed so casually from your mouth. "That's twice now. Thrice and you may not enter my room again until you ask Jesus' forgiveness." she adds, her cute brow furrowed.
"Sorry... but I saw them. I didn't know they were panties. They looked so nice and silky for my nose and it smelled so good to me." You drop the panties pretending they're something filthy.
"They smelled good?" she asks, beginning to giggle again, "bu they were on my bum."
"I know, but..." you feel you may be able to plant a seed in her mind. All you can think of is her dewy blond fuzzy virginal cunt right there in the room with you. "I don't know, it was an animalistic scent. We've watched nature shows, right. Remember that one where the gorilla sniffs and licks the female's, um, vulva?
"Yeah, that was funny, remember?" she says.
"Yeah, well, we are creatures with scents and hormones, well... maybe you're giving off a scent, like, you know, maybe you're fertile and, well, maybe your body is sending signals for males to mate with, even though you're not aware." you try to appear as much like an instructive big brother as possible and not the incestuous big brother you wish you could be.
"Your scent really affected me. It made me almost crazy." you lick your lips and let your eyes move down slowly to her crotch for effect. Marissa instinctively holds her arms down protectively in front of her chest, her hands over her vagina, a serious contemplative look on her face.
You amble out to your room.
"G'night gorgeous." you say over your shoulder.
"Night." she whispers.
She figures that she must have misunderstood, but it seemed like you thought her vagina smelled nice.
You're not sure if you got her thinking along the lines you intended. Unknown to you, Marissa has very disturbing dreams of you pressing your nose into her bare pussy, sniffing and sniffing while she tries unsuccessfully to push your head out of her crotch. She tries to not think of the part of the dream that wakes her convulsing in an orgasm, the part where you hungrily lick and suck on her vagina.
During the day you decide you need to do something ...
