This was a piece of piss to do.

Len woke up groggy in the morning, and his dick was throbbing. He dreamed of Rin giving him a golden shower.

But he needed attention now. He lifts his ass up a bit, then lets out a moan, straining softly to empty his bladder. And then his pants darkened. The gold fluids flow around his crotch, then down between his asscheeks, finally hitting the sheet. His cheeks deep red, he rubs his still flowing cock, gently caressing the soft skin on the bone.

Suddenly he feels a massive insertion! Looking down, he sees his sister, soaked in familiar fluids, fisting his ass rapidly.

"You should make sure you aren't sharing the bed with someone when you pee your pants, Lennie!" she says playfully, seductively. And then, rotating over to his head, she releases a jet of piss onto Len through her panties.

Len drinks and drinks...

Then he woke up.

"...wow... I'm fucking hard."

"Me too, bro..."

Rin is a futanari apparantly...THE FUCKING END
