The shower before bed was shorter than ideal. It was a small hot water system, used to two or three showers a day, but my sister Sarah and I had challenged its capacity getting cleaned up after repeated sex.
Sarah put an extra blanket on the bed. She wanted us to sleep naked and have easy access to each other's bodies. Sleep? Yeah, it might happen...
A little after nightfall, hugging side by side in bed, I felt emboldened by the darkness. Sarah was gently stroking my chest hairs, her head on my shoulder.
"Sair? I'm curious. You've had steady boyfriends, one or two might even have been
nearly
worthy of my sister! You got anybody in your sights right now?"
"Nah. I like sex but I'm not ready to 'settle down' as mum used to call it. And I don't do one-night-stands, so it's a steady man or a drought for me. And... oh, forget that."
"What?"
"No, nothing."
I tickled her. "Nothing my bum! Tell or I'll tickle you to death!"
"OK, OK! Stop!" We rearranged the bedclothes that had been tossed by her wriggling and settled back into each others' embrace. Sarah got serious.
"Dave, don't freak, OK?"
"I won't. Jeez baby girl, is it that bad?"
"Maybe, maybe not. Oh shit. Look, when I got upset because I'd gone potty-mouth on Friday, you must have wondered why I am OK fucking my brother but not with dirty talk?"
"It crossed my mind..."
"Well, two of my boyfriends left me because they told me, and some of my friends, that I was a complete slut. Not because I'd cheated on them - I hadn't - but because they found some of my, um,
tastes
a little bizarre."
I hugged her for encouragement, and said: "Their loss. Fuck 'em."
"Yeah, but, I think I can trust you. So here goes. I wanted to try anal and watersports. There, I said it."
"Jesus Sair, I thought you were gonna tell me you got horny looking at horses' cocks or something. Did you find these guys at the Young Christian's Anti-Fun League or something?"
She laughed, partly at my joke but mostly in relief. I lifted myself onto my shoulders, with her underneath, and kissed her fully on the mouth. "Thanks for trusting me with that li'l sister."
"You're not freaked out?"
"Hell no. I'm your man. I've done both and it's fun!"
In the dim light I could see open-mouthed delight on her face, then she spoke: "Alright! Cool. Not now though. Climb on top and give me a quicky?"
"Not sure if I can manage a quicky, my balls are probably dry..."
"No,
give me
a quicky. We'll sort you out later. I'm gonna think of peeing with you and getting your dick up my bum..."
She spread her legs, I got between, and sank into her hot wet tunnel. She cooed, bit her bottom lip, and began pushing her hips up to meet mine. This one was for her, so I arched my back and kiss-nibbled her nipples. Even in the dim light I was again in awe at their shape. Laying there as I gently fucked her, the perfect orbs moved only slightly to the sides, so firm were they.
After a minute or so, Sarah angled her hips and tipped me sideways. I completed the move until she was on top, riding me gently, my hands now massaging her breasts and pulling at her nipples. Looking down I could just make out her bald pussy lips stretching to accommodate my cock, almost closing at the top of her stroke, then parting when she sank back.
Sarah put a hand between us and played with her clit. Before we got too far into the sex, I pulled her back towards the wall, still with my cock in her, put a pillow behind me so I was half-sitting, and gripped her buttocks while I matched her grinding with my hips. I had a reason for that.
Reaching behind her, I put my index finger in my sister's pussy beside my dick, getting it wet, then teased her asshole open with it. Her breath quickened in anticipation. Thanks to my positional change, it was easy to get one finger all the way in her bum. Sarah moaned as it slipped past the hard ring in there, then again when I pulled it sideways to make room for the middle finger. She wriggled a bit to improve the angle, then I had two fingers in my sister's ass while she rode my cock, her fingers still diddling her clit while she pulled and twisted her own nipples with the other hand.
I fell into a rhythm which soon had her gasping. When she sank down on my cock, my fingers were half-way in her ass but when she lifted I pushed them up there hard. I could feel my own cockhead through the thin layer of flesh separating those two holes, and I found that by curling them backwards a bit I was rubbing against my cockhead while it was inside my sister's pussy.
The two fingers on Sarah's clit began to blur as her movements lost rhythm and became jerky. She was cumming. I used the trick up my sleeve to tip her over. Lifting my hips high, I held my cock deep inside her and pushed my fingers in her ass, holding them there.
"Oooh Dave! Oooh. Oooh. Stay there. Don't move. Awww. Oooohhh!"
In the moments before crescendo, Sarah put a hand on my chest as her thighs bucked back and forth. I watched in lust as her tits jiggled just in front of my face. Craning forwards I was just able to suck a nipple into my mouth, and that sent her into a long, slow orgasm that she ground out on my cock, moaning all the while, before collapsing forward onto me, arms around my head and cradling me to her breasts.
I still had my fingers in her ass, and I finger-fucked her gently. She responded with the gentlest of hip movement back against them. I kept it up for some minutes, in silence so I didn't spoil the afterglow for her.
I hadn't ejaculated so of course I was still rock hard in her pussy. But I almost came when my fabulous sister whispered in my ear: "OK Dave. Let's do it. Fuck my ass."
She was smiling wickedly and I was not going to need a written invitation. I scooted behind her, she on all fours gripping the bedhead on the top. I could see her dripping pussy and open asshole. I put my cock in her pussy for lube, held it in my hand against her pucker, and pushed gently.
My cockhead went in easily, Sarah gasped and cooed: "Oooh yesss. I knew I'd like this. But gently, li'l bro..."
I leaned forwards, and found resistance there. But it was slowly opening, so I just stayed put.
"Oh Dave. That's great. It's gonna open up for you. Just...Ohhh..Wait a sec..."
Then it slipped past slowly:
"Ahh fuck. Hold it for a minute..."
I stayed still, but my cock was engorged and throbbing. Her pussy was hot, wet and tight. Her ass was hot and tighter. It was like a heated fleshy glove gripping all the way around, and I swear I could feel vibrations there when she moaned and spoke.
Then Sarah began a slow backward thrusting. I pushed against it, gradually lengthening my strokes, until after a little while I was properly fucking my sister in her ass. My mind ran through a dialogue that speeded my cum on its way:
Jesus. You're fucking your sister in the ass. Look at it going in and out. Like it did in her pussy, just before when she rode you, and earlier on the breakfast table. Her cunt is amazing, and her ass is too.
She's
amazing. And...oh fuck I'm gonna cum soon.. And she wants to piss on you, and you on her...think of that, look at your cock in her ass. Your
sister's
ass, Oh here it comes...
Slipping back and forth easily now, the tight friction on my cock was heavenly and before I could make sure it was OK with her, I jetted gobs of cum up her ass
jsst, jsst, jsst...
She squealed at the last thrust, hard up, perhaps a little painful for her, so I eased off mid-orgasm while I finished half-buried in her. If anything it intensified my pleasure. Now my cock bent and straightened in time with my pulsing jizz, fairly throbbing it into her.
She let me finish, then said: "Take it out slowly Dave, it hurts a bit."
Allowing her to guide the pace, my cock edged outwards until it had passed the tight nut of her sphincter then slipped out altogether, bringing a gob of my cum with it. I watched it slither out of her asshole and down beside her puffed pussy lip, then slowly down her thigh. Always ready with the phrase to lighten the moment, Sarah piped up:
"You really are a perve. You fuck your sister's bum then watch the goo seep out!"
I grinned in the dim light. "Mmm. Looks hot."
"You wanna perve some more?"
"Huh?"
"I need to pee."
"Oh, all right! Cool. Um, what exactly do you have in mind?"
"Oh, I'll let you watch me, touch me if you want. But mostly I er, I wanna piss on you? On your chest? Maybe on your dick?"
"Yeah that's cool. I don't want it in my mouth though..."
"OK!"
In my mind I joked with myself about this conversation. I was discussing the ground rules of watersports with my sister as if we were discussing what to have for lunch.
She led me by the hand to the bathroom and ran warm water in the shower for a little while to wash my jizz away. Then I climbed into the shower and knelt between her thighs.
"Lick me a bit first?"
I did. She was salty-sweet from the sex, and now in the full light of the bathroom I once again marvelled at the perfection of her pussy. Even after swelling from riding my cock, her labia were hardly pronounced. She had the slightest 'mound', split by those gorgeous wrinkles of flesh that enclosed her vaginal tunnel. I licked at them lovingly. She bent her knees to get better contact, hands on my ears.
"Mmm, if you ever say you won't lick my pussy again I'll be forced to kill you."
"Then I wouldn't be able to..."
"Fair point. I'll kill your mates instead, one by one, until you lick me again. Ooh. Here it comes. Look out..."
Leaning back I saw those delicate petals forced open by a hissing stream of pee which hit me on the chest then stopped. A dribble down her thighs, then another.
Sarah was watching me and her own pussy, then grunting she pushed hard and erupted in a strong stream that lasted three or four seconds - just long enough for her to adjust her hips and get some directly on my cock, part-erect, which twitched into life and rose to full mast again.
"Ooh Davey! I think he likes his sister peeing on him!"
"He does. And so do I."
"Here's some more then."
She managed to relax her insides fully and empty her bladder on me. I'm not sure what was hottest: Was it my sister letting me watch her pissing? Or just me watching my sister piss, maybe feeling the hot stinging on my body, or perhaps hearing the long
pfpssssstttttt
as it came out strongly.
Whatever it was, my cock strained and throbbed. When she'd finished, I took a chance and licked the last drops of piss off her. Not great, not terrible. As I licked, the taste went back to 'normal' - just good old pussy.
Still licking away, I asked my sister: "All good?"
