Incest Seduction/Ask Kim what she has planned today
"So... what have you got planned for today, sis?"
"Nothing."
"Really? Nothing at all?"
She slips further down your torso, forcing your hand even higher between her legs.
"Nope. No plans. But I'm up for whatever you want to do. Or nothing at all," Kim adds, nuzzling into you again. "I'd be totally fine with laying on you all day."
"I can't sit here the entire day. For one, I'll have to change my laundry at some point."
"Oohhh..." she groans. "Do you have to? You feel so good..."
Kim slides the rest of the way down until her head is resting directly on your crotch. Speaking of crotches, her final descent forced your hand the rest of the way into her's. Feeling your fingers butt up against the soft mound thinly concealed beneath her yoga shorts you immediately pull your hand away. You bring it back down onto her side, just above her hip, trying to seem as aloof as possible about the entire thing. She had to have felt that, but she isn't saying anything.
"Umm, yeah... You too."
She purrs in agreement and sends tiny vibrations down to your cock. You wish you weren't wearing sweat pants. It's bad enough that her face is nearly resting on your dick, but the sweats offer far less physical protection than, say, jeans. Arguably, they are also more comfortable to rest one's head upon, not that that's the first thing you think of when deciding on what to wear on a given morning.
"Ry? Would you mind petting me?"
The request catches you off guard, interrupting your wandering thoughts.
"I guess... sure."
You bring your free hand to your sister's head and begin to pet her in slow firm strokes from her forehead to her ponytail. Your other hand joins in unconsciously rubbing your sister's side, slipping up under her shirt then back down to her hip.
"Mmmm. That's so nice."
Much to your dismay, Kim gets a bit more comfortable. She wedges one of her hands between her head and your crotch, her arm running up between your legs. Getting her head further away from your dick would have been fine if it didn't also mean that her palm was now resting atop it lengthwise.
You keep petting Kim, almost out of a nervous obligation. But that really isn't helping things. Caressing and cuddling your sister so intimately has brought your dick to twitch more than once. You should probably do something.
Tell your sister that her hand is on your cock.
