You need to get ready...

You're mostly dry from the shower, and even though you just pasted ropes of cum all over the back shower wall, you're still half-hard and bridging the towel like you're trying to smuggle a fat bratwurst under it. You've barely managed to catch your breath when you leave the bathroom.

And there's Liz, grinning like a cat. She's wearing a camisole. Nothing else. It's barely long enough to cover her pussy, the silky black material plunges so low it's basically exposing her tits, and you suspect the only thing holding it up is her diamond-hard nipples.

That got the blood flowing again. Fuck. Then again, so did the way she was looking at you. Blushing. Shit, is she out of breath, too? Did she go into her room and masturbate while you were getting off thinking of Clarissa and her in the shower?

"Enjoy the shower?" she smirked? "Get everything nice and clean?"

"Enjoy while I was in the shower? Get almost as wet as I did?" you snap back. It felt good. The playful banter, it's like being in college, but dirtier...filthier...more taboo. Fuck, Liz is your sister! Your little sister. With that bright pink, soaked pussy.

Jesus, can you smell the pussy juice from here? Your sister's pussy? You bite your lip as your thoughts rocket through you and your cock threatens to tent the towel even more.

"Fuck...almost..." she said and pushes past you, rubbing herself against you as she moved. There is plenty of room in the hall way, she didn't need to rub her mound against your cock as she move, didn't need to rub her tits against your chest, and she certainly didn't need to slide her fingers over your hard, exposed cock as your fingers slid under the fabric of the camisole.

Fuck she's wet...fuck her fingers are hot on your cock...fuck....

Wait...what the fuck just happened?

"Mmmm....welcome home, John," your sister purred, and she makes a show of licking the fingers that stroked your hot, throbbing meat before turning and walking toward the washer and drier.

What the fuck just happened? You're not sure, but you like it....
