"God David, I was going to wait until you came downstairs, but the sight of your fat cock is making me even wetter than I already am. See, I really did come up here for another pair of panties. When I was on the flight I had to pee, but DC has that stupid rule that no one is allowed to get up 30 minutes before landing. I tried to hold it, but I couldn't so I sort of wet my panties. That's why I was so quiet in the car. I managed to pee when we landed, but my panties were still soaked with piss. And then when I came up here I saw your thick dark cock, and I was reminded that you like that sort of thing, and that I've always wanted to taste a brown dick. Alison told me about the nasty things you two did, and since I'm here this weekend as one of your birthday presents, I figured I might as well skip the panty change and get the party started...what you think?"
I was pretty stunned. I had assumed that Alison's drunken revelation about golden showers had either grossed Ashley out, or that the both of them had simply not talked about it very much at all. When I finally swallowed the lump in my throat I put one hand on Ashley's ass and pulled her close, and whispered in her ear. I asked her what Alison had told her about our games.
"Alison told us how intimate those golden showers were. She said that there was something magical about feeling your hot golden piss cascade over her breasts. She told me how intoxicating the smell was, and how she would look into your eyes as you pissed onto her tits, and how she would rub your piss onto her tits, looking at you and sticking out her tongue, asking you to piss into her mouth...I didn't understand at first, and then Alison explained that it was the ultimate act of acceptance. She told us how you would lick the piss off her face when you were done, and how sometimes you would use her piss to lubricate her asshole...I want you to do that to me David. I want to wash my face in your piss, and drink from your cock, most of all I want your dark cock in my ass..."
As Ashley finished telling me what she knew, I started pulling her skirt up over her ass, to reveal a pair of white cotton panties that barely covered her butt cheeks and were clearly yellowed with piss. I stripped off my boxers and we went into the master bathroom. Ashley, still had her tank top on, and as I freed her firm white tits from the confines of her baby tank, she licked her middle finger and started running it down her ass-crack. Ashley was now naked except for her damp panties. As she stepped into the tub, I rubbed my hard cock along the crotch-band of her panties, as she cupped her tits together.
I asked Ashley "Do you still have to pee?"
"Um, yeah, I really have to go...." I told her to piss on my cock. She was kind of nervous, but as I kneaded her white tits with one hand and started running my fingers down her luscious ass crack with the other, she managed to relax and let go. Her piss was pungent, and felt nice and hot on my cock. A lot of it flowed down her thighs, and I started to cup my hand to catch it and rub it all over her big tits.
Ashley, seemed to lose control at that point, and kneeled down to start licking my cock. She looked into my eyes as she snaked her tongue along the length of my fat cock, licking up her leftover droplets of piss.
"Mmm...David, I love the taste and smell of your balls...they're so nice and sweaty...are you going to let your slut sister in-law drink some of that dark cum? Don't you want to cum in my mouth baby...I'll drink it all up, I promise. I'm just like Alison, I love drinking from your cock, it tastes so good, so salty."
Ashley started rubbing my cock all over her face, and then asked me to turn around. I felt her soft pink tongue in between my ass-cheeks. I reached behind me and grabbed her head and pushed her face into my ass. Ashley started to sniff my asshole, and I felt her alternate between slowly licking my puckered asshole, and inhaling my scent. Fortunately for me, our bathroom has a floor to ceiling mirror across from the tub, and as this bubble butt blonde slut starting sucking and licking me I was able to watch her every move. It was an amazing site, my gorgeous blonde sister in-law mewling with delight as she cleaned my asshole with her prim and proper mouth. I watched as her perky tits were drenched in her own excess saliva as it dripped out of my ass.
"Oh, David, this is so amazing. I love the taste of your asshole, I can taste your shit and sweat on my tongue. Give it to me baby, I want to taste the inside of your ass. Mmm...baby are you going to let me drink some of your piss after I clean you shitty asshole with my tongue? Please baby, I want to taste your hot golden piss in my mouth....Oh baby, I love being your nasty blonde slut." I was on the verge of losing control, so I had Ashley stand up and lean against the wall. I started to started to rub Ashley's ass through her panties. I moved behind Ashley to remove her now piss soaked panties, and it took all of my self control to go slowly. Ashley's beautiful heart shaped ass was glistening with piss and sweat, and her blond pussy hair still had a few droplets of piss. I got down on my knees and started to lick Ashley's pussy clean. Her pussy was so perfect, she tasted like a woman should taste, sweet and salty and full of musk. The odor was overpowering and intoxicating. I wanted to cover my face in her juices, and her scent. I flattened my tongue and ran it along the length of her pussy lips, occasionally thrusting my entire tongue inside, trying to drink as much of her liquid as I could. As my tongue lapped at her clit, I started finger-fucking her pussy and her ass, and between my fingers and tongue, Ashley began to cum...
"Lick my pussy, you motherfucker...do you like the taste of my golden piss and my pussy juices?...I want you to fuck me with your tongue and lick me clean...Oh, I can feel my asshole stretching for your fingers. Yes, push on the insides of my ass, pull my dark hole open. Can you smell my ass now baby. Oh, yeah keep going, keep licking...faster, faster, faster...Yessssss..."
Ashley's thighs started to quiver as she came, and she slumped against me as her orgasm overtook her. After a few minutes, she noticed my hard cock wedged in between her ass-cheeks and stood up. With both of her hands, she reached behind her and spread her huge white ass cheeks and told me to get her asshole ready for my cock.
"Alison told me what you really wanted her to do...When I heard about it, I just had to try it, its just so nasty. Come on baby, lube my ass with some of your hot nasty piss. I want to feel your scalding golden hot piss run over my cheeks and onto my asshole. Take some of that piss, and rub it onto the inner walls of my ass, so your hard cock can slide right in...I want you to fuck the shit out of my white butt. And when your done, I want you to come in my mouth, so I can lick my dark chocolate shit off your gorgeous thick brown dick..."
I didn't have to be told twice. I looked down at Ashley's ass, and I could see her puckered hole, it was stained brown, and started throbbing as I let my first dribble of piss go onto Ashley's butt.
As David's piss hit me, it all became real. Here I was, naked with my brother in-law, with my ass spread, being pissed on. His piss was scalding, and it smelled really rank. I turned to look at him, and saw that the piss from his cock was a dark yellow. The look on his face though was amazing. He was so focused, and so clearly into it. I started to feel a tingle in my asshole, and realized that I was really horny. David, caught my stare and with his free hand he forced me to look him in the eye. He asked me if I was his nasty white piss slut. At that moment I realized that I was...I wanted to feel his piss inside my asshole, and I also wanted to feel his hard dark cock inside my ass. Just then, I felt David's fingers spreading my asshole again. My sphincter resisted at first, but then as David gently pushed outward, by asshole began to stretch, and David's hot piss started dribbling into my anus. His fingers started spreading it around, and pretty soon, he had three fingers inside my ass, and it felt really good. Then I felt his cock enter me, and it was so thick, it stretched me even more. As the mushroom head went deeper into my ass, I felt it rubbing against the walls of my ass filling me up. And then, it stopped. I turned to look and David still had another few inches left. He reached around to pinch my nipples and have me lick the piss off his fingers, and he told me that I was apparently full of shit. I realized that the few drops of David's piss that I had just tasted were bitter. As the taste faded on my tongue, I realized that I wanted more. I wanted to savor the bitterness in my mouth. It was so extreme and nasty, that I had to taste it again.
