On Joanne, not in front of her. (Golden Shower)

"How will you make it worth my while?" asked John, squeezing his knees together trying not to pee.

Sara put the ballgag back into her sister's mouth and turned the setting on the vibrator up so Joanne could orgasm from it. If you pee in front us, I'll let you piss all over Joanne's naked, bound, and exposed body while you do it.

Joanne's eye were practically bursting out of her head as she screamed, struggling as hard as she could to break free of her binds. Joanne did not want to get peed on, and was freaking out, **** to prevent it from happening.

John was blushing a lot with embarrassment when he heard Sara offer this. "Why would I want to do that," asked John pretending he didn't want to.

"Oh, I thought you'd want to, nevermind then," said Sara starting to walk away. "come on Joanne, let's go," she added.

The two girls hadn't made it two steps away from him when John yelled "wait!" Joanne had calmed down by this point, but now she was starting to worry again.

"Yes?" said Sara pretending she didn't already know what he wanted.

"...I have to pee," John said quietly, feeling embarrassed.

"What do you want me to do about it?" asked Sara playing dumb. John's mother stood there watching the whole thing unfold, enjoying her son's humiliation. Then she suddenly had the idea to film it, and took out her phone.

John mumbled something that no one understood. "I'm sorry could you speak a little louder, please?" asked Sara.

"I want to pee on Joanne," whispered John, his cheeks turning as red as his previously spanked butt.

"I couldn't hear you, can you repeat that please?" asked Sara pretending she couldn't hear him.

"I want to pee on Joanne," said John, at an audible level, while staring down at the ground. His cheeks were blushing a deep shade of crimson.

"One more time please?" asked Sara.

"I want to piss on Joanne! I want to piss on Joanne! I want to piss on Joanne! I have a golden shower fetish and I want to piss all over your sister's naked body! Are you happy now?" yelled John feeling annoyed, stomping his foot on the ground, again causing his erection to slap his stomach.

John realized what he just yelled and his face was flushed with embarrassment. Joanne was suddenly moaning really loud. Just then she had a massive orgasm while screaming through her ballgag and fell to her knees.

"Okay, go ahead now seems like a good time to do it anyway." said Sara

John grabbed his dick and aimed it at Joanne while she was still on the ground recovering from her orgasm. Before Joanne even knew what was happening, John started peeing on her. _"I can't believe this is happening, I can't believe I'm actually pissing on a naked girl!" _thought John.

Urine was shooting out of John's dick in a long continuous stream. Joanne screamed, cried, and struggled as she tried to beg John to stop.

While John's piss sprayed all over Joanne's naked body, John's mom was recording the whole thing. Both Joanne and John were being recorded as the golden liquid coated Joanne's face, hair, breasts, stomach, and the rest of her body.

John had a look of pure pleasure on his face as he finished pissing all over Joanne. Sara watched, grinning as well. She was enjoying what was happening to Joanne.
