Jen uses your home bathroom

One midsummer day, you invite Jen over to your house since your sister was in the middle of vacation on the other side of the world, and so there was no chance of anything bad happening, or so you thought...

After watching an enjoyable romantic movie together, Jen asked to use the bathroom and you accept, seeing no problem with that. A couple of minutes later, you hear Jen scream "FUCK YES!" from upstairs, so you rush upstairs to see what the matter was.

When you arrived in the bathroom, you noticed that Jen was in a state of pure bliss as three relentless streams of cum erupting for the toilet, the wash basin and the bath itself. one directed itself into Jen's pussy, one into her asshole and the last into her mouth.

After you recover from the initial shock of the situation, your mind went back to what happened immediately before your sister went on holiday three weeks ago. She had filled not only the entire bath, but also five buckets with her cum, saying that it was a little gift for Jen before she left, but that you could get rid of it if you wanted to.

It was then that you realize that the cum currently filling up Jen to a ridiculous degree was the same cum that you had disposed of three weeks earlier. You realized your sister had programmed her cum to start filling Jen the moment she was within range. With that mystery solved, your mind wondered when the cum would stop...

Pondering this thought, your mind went back three weeks to when you were busy disposing of the cum, using dozens of cloths to scrape all but the tiniest scrap of cum from the first bucket after dumping the main load into the basin. You repeated that for the remaining buckets until you noticed the first bucket was completely filled again.

You went pale at this realization. What if the cum that you washed down the drain had been multiplying like it did in that bucket for the past three weeks? If that was the case, would the stream ever end?

Hating yourself for being as stupid to think that the reality-bending monolith of absolute power that was your sister's cock wouldn't be able to do anything to Jen simply because she was on the opposite side of the world, you drowned yourself on your sister's cum as she did to Jen from thousands of miles away what you were unable to do to her despite being in a happy relationship with her for the past six months; give her enjoyable sex.
