Golden shower/ Kate takes control

Kate seductively got off the toilet and slid the door to the shower open. I'm not sure that she had ever looked as sexy as she did when she stepped inside with me. I moved to kiss her, but she put a hand on my chest and shook her head.

"On your knees," she ordered.

With the hot water beating off of my back, I dropped to my knees in front of my pregnant wife. As she smiled down at me, one hand went to her breast and tweaked a nipple while the other went down and gently rubbed her clit.

"Looking good down there," she told me as she stepped forward. My face was now just an inch from her pussy and the hand she was masterbating with. "You know, there is something I've always wanted to try but until tonight I've always been too embarrassed."

"What's that?" as I started stroking my cock again.

"I'm gonna show you, in a minute," Kate said. "After the baby went to sleep, I came back down stairs for a drink. Guess what I found in the kitchen?"

My mind went back to Marcie and I was suddenly filled with panic.

"Look, I-"

"Shhhhh," she said. The hand rubbing her pussy was moving faster. "After your brother, you owed me one. And Marcie is trying to get pregnant. Its okay this once. I'm not mad. But I had to watch my husband worship my sister's pussy and then creampie her, so you still owe me."

"You saw the whole thing?"

"I saw everything," she said. "Now open your mouth."

I did as I was told, and she stepped forward again, placing her pussy right on my face.

"I was always embarassed to tell you I wanted to piss on you, but after Marcie, I get what ever I want."

She and I locked eyes and she smiled. Without hesitation I felt a warm wet rush flood my mouth. She placed a hand on the back of my head and held me in place as she pissed into my mouth. I had to swallow it to be able to breath, and still I found it hard to keep up, nearly choking pn my wife's piss several times.

"Thats a good boy," Kate said as she took what felt like the longest piss in history. "Momma's gotta mark her territory."

She finally stepped back, the last few drops of piss tripping into the tub.

"I know you find my sister is attractive, who wouldnt? But you remember who you belong to. Now finish jacking off for me."

She stepped back and watched as I got a good grip on my cock and started stroking it.

"Whose cock is that?" she asked.

"Yours, Kate," I said.

"Whose balls are those?"

"Yours."

"Whose piss are you going to start drinking on a regular basis?"

"Yours?"

"Thats right," she said. "Maybe its just the pregnancy hormones talking, but I feel the meed to take charge of things in this relationship."

She slipped one foot under my balls and gently but firmly began to grind up into them. I kept stroking.

"I just watched you creampie my sister, I should be kicking you in the balls now," she said, and for a moment I wasn't sure that she wasn't going to. She even added a little pressure as if to show me she might. "Part of me wants to bust your balls right now. But another part of me loves you and doesn't want to hurt you. That part wants tp show you who the boss is and remind you that your cock and balls are mine, understand?"

Then she did bring her foot up hard, causing a sharp pain in my testicles. At the same moment I came, shooting my seed all over the shower.

"Now you understand," she said with a smile. "Come to bed and cuddle with me."
