Incest Seduction/Leave your hand on her thigh
You're thinking too hard. It's not a big deal. It is just your sister after all. Besides, after her heartfelt admission, she may not appreciate if you pull away from her now. Okay, so you're over-thinking this...
You leave your hand on her thigh but you stop rubbing her skin, sort of meeting halfway. You hadn't meant to keep doing that anyway.
"Well aren't you two cute together!"
Mom comments as she passes through the living room, still nursing her coffee and still in her robe.
"Go away, mom..." Kimberly replies in a slightly too serious tone.
"We're just watching TV," you add, your words more defensive than necessary.
Mom holds one hand to her chest in mock offence. "I'm allowed to think my kids are adorable! You should cuddle more often!" She winks at you before shuffling off to another part of the house.
You cautiously glance down at your little sister. She's slid further down your torso but is still hugging you just as hard as ever. Her hair is pulled back into a ponytail giving you an unfettered view of her shoulders and her tank top and her lacy pink bra. You are forced into a double take on that last one, peering down the front of her shirt more purposefully. It seems pretty early on a Saturday to be wearing such sultry underwear.
Kim looks up at you, smiling yet again. She caught you staring. You smile back awkwardly before averting your eyes. She sure is acting weird. Then again, perhaps you're acting weirder.
