Sister Hits a Snag

The warm spray of the shower helps your body relax, but you're still mentally processing everything that just happened. Getting a handy was great and all, but it was just so unbelievable. You had no idea your sister would be so willing to touch your dick, and the rough handling with which she did it makes you feel a little uncomfortable. Nothing bad happened this time, but you wonder if she might accidentally break something if it keeps going like this. Should you try to alter the deal somehow?

Just then, the bathroom door bursts open. Through the semi-opaque shower curtain, you see Jan's blurred form rush to sit on the toilet. And she immediately jumps back up.

"Dammit, bro!" she yells. It seems you forgot to put the seat down. She slams the seat down and quickly sits again.

You sigh, then say, "Sure, come right in. No problem." You make sure to put some extra sarcasm into it.

"Oh, shut up, dude," your sister retorts. "It was an emergency."

You shake your head and shut off the shower. You were pretty much done anyway. But as you reach out for the towel hanging on the hook just outside the shower curtain, Jan objects.

"No you don't! You stay right there 'til I'm finished!"

"What? Why?" you ask, genuinely confused.

"Because you're naked and I don't want to see your bare ass any more than I have to. You can dry off in the shower."

You sigh and close the curtain again, then resume waiting for your sister. Does she realize that she's basically forcing you to be an audience to her pee? Well, not like it really matters, since you've heard her pee more times than you can count. Just not so close up before.

"You better not be jerking off in there," she says. "That's not the deal, mister."

"I'm not!" you exclaim, a little annoyed that she's bringing it up.

After a long awkward silence, your sister finally finishes up. She stands, pulls up her pants, and flushes. A few seconds later, she flushes again. And again. And then you hear the unmistakable sound of a toilet overflowing.

"Shit," you and your sister both mutter at the same time.

You open the shower curtain and step out, finding your sister backing away from the toilet and looking lost. You see water pouring over the edge of the bowl, and a small flood is growing across the floor. Muffled yelling can be heard from the downstairs apartment. You grab your towel and flee to your room.

Later, after much mopping, toilet plungering, and sanitizing, the two of you are back on the couch.

"So, uh," you venture. "Flush anything funny?"

"One condom isn't going to clog anything up!" says Jan defensively. "Besides that, I've only flushed normal stuff."

"Normal stuff?"

"Yeah, you know... paper... waste... wet wipes... kitchen grease..."

"Kitchen grease?"

"Yeah," your sister says. "You're not supposed to dump that stuff down the sink, you know?"

You open and close your mouth a couple times before finding words again. "Okay, well, putting that aside for a second, there's something else we should get settled."

She nods. "Right. If you're gonna spooge so much that it's bad for the plumbing, I'll have to come up with a new plan for you."

"That's not what I..."
