Step daughters/Asexual/1st Wednesday/pleased Sandra/Masha Watches Sex/Calm
Well, you don't want to traumatize the poor kid too much about all this, so you just give her a gentle smile. "Oh, I didn't know you liked watching this kind of video." You say as you sit down next to her and get a better view of her hand, noting that it's actually going inside her underwear. She hastily pulls it out when she catches you looking.
"Hey, that's alright, you can rub yourself there if you want." You tell her. "It feels good, doesn't it?"
She just scrunches up her nose and turns to you with an incredibly exaggerated look of shock, disgust, and confusion. She'd going the whole 9-yards with the act, reeling her body back as she looks you up and down with that sour disgusted face of hers. "Mommy says we're NOT supposed to touch ourselves there!" She states quite defiantly. "She yells and punishes us and everything!"
You just sigh, that's kinda expected. "Well, yeah. I noticed that about her. She probably wouldn't really like you watching this video either, but... it's Ok. I won't get you in trouble for watching this or for touching yourself, we can keep it a secret from your mommy."
She's still giving you a little bit of stink-eye, and looking at you with a lot of suspicion. She quickly gets distracted though by the action on screen as the boy is angling his penis toward his sister's vagina at his mother's direction.
"Hey! What's that thing that boy has?" She asks, and then gasps. "It's going inside her!? Down..." She spreads her legs and looks straight down at her own crotch for a second, before her head snaps back over to you and she looks at you with suspicion again.
Well, this really hasn't been going quite as well as you'd hoped so far, Masha seems far more resistant than Sandy.
