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...
