Dirty Hobo

It doesn't take you long to pull a shirt and pair of pants off the top of the laundry bag. Fuck, they stink. They smell like everything smells in the apartment, like Katie's insatiable, dripping snatch. Maybe it smells just like your sister's pussy. That thought burns into your brain as the image of Jess madly fingering her clit on your bed returns. You pull the clothes on quickly and try to tuck your cock down your thigh and not make it look too conspicuous.

You fail.

"Tom?" Jess's voice comes through the door and there's an urgent knocking. You don't have your shirt on yet and your dick is sticking up like you're trying to smuggle a summer sausage down your thigh and the door opens and your sister moves in with a quick flurry of movement, shutting the door behind her before she spins to face you, her hair a flurry around her head. It takes her another second to actually focus on your face after your gaze slides up your chest.

"I was worried you might be....you know...but fuck, Katie is wild today," she said, making a conscious effort to look at your eyes. She fails, too. You can see her pupils flicker down to your crotch several times while she talked and then again twice during the silence filling the room.

Neither of you seem terribly interested in talking, both of you are obviously extremely revved up, and there's a bunch of awkward glances as your sister's nipples harden even more through her shirt and camisole and your dick refuses to go down.

"So umm....I might be what?" you say after what feels like a year.

She doesn't answer but she blushes bright red. "You know. Like...." she mumbles and then almost so quietly that you almost don't catch it, "like last year..."

She wanted to catch you masturbating. Jesus, did she want to watch? Katie really does have her revved up. Fuck...it's been a hell of a morning already...

"Well, are you sorry that you didn't?" you blurt out.
