Fantasising About Emma - Donor Ch. 13

She swallows my spunk and licks me clean. "Yum," she purrs, with a smile.

"I want to watch," I tell her. "Promise me I can watch you fuck your brother. It doesn't have to be the first time, but I have to see it."

"I want you there the first time. But you aren't going to be just watching..."

***

Time continued to fly by. When I wasn't working or on my long commute to work, I was doing interviews for jobs closer to home. I hardly saw Emma all week. But she kept herself busy.

On Monday, she got arsefucked by Mark, which she said hurt but was "fricking amazing". On Tuesday, she went to Cathy's for a girly-night-in and they wound up sharing a double-ended dildo. Wednesday: she went shopping and helped some guy who was shopping for his wife's birthday present in Victoria's Secret by modelling outfits for him - and then fucking him. Thursday evening she spent at a spa getting pampered (and 69ing her masseur). And on Friday, she went out on the town and spent the night in a university dorm with a couple of students.

And somehow, between all these adventures, she organised our wedding party.

The day went great. Emma had booked the local rugby club again - the team her brother plays for, and where she had her 30th birthday party - and had done an amazing job with decorations.

We recreated our ceremony for our friends and family. Emma's mum and sister didn't come, but everything else was perfect. Emma looked almost exactly the way the did on the actual day, with the same hair style, the same blue tongue piercing, and a bracelet she'd found that matched the one she'd borrowed. The only visible differences were the new piercings in her ear and nose.

The non-visible differences were under her dress. She was wearing the same white patent leather stiletto boots, but that was it. No underwear - she didn't want anything to get in the way of her brother's dick.

I was besotted all over again. We'd been holding hands almost all afternoon, and we still are now the party's in full swing.

There've been so many people congratulating us, and it seems I don't know the vast majority of them. Emma's always been popular, and her family is bigger than mine, so our invite lists were lopsided. It's been cousin followed by aunt followed by friend from work...

But Alex hasn't spoken to Emma or I once, outside of a tense moment in the receiving line before dinner. He's spent virtually the whole time propping up the bar.

Emma wanted to leave him until he was pretty drunk. He's a mountain of a guy - a flanker for his rugby team - so it could take a lot of alcohol. I could tell we were both surreptitiously watching him all evening - I was even counting his drinks. After his seventh beer, I suggested now was the time.

I sense a little tremble of excitement in Emma as we make our way across the room, and she taps him on the shoulder.

"You've been here all night. Hoping I'd dance on the bar again?" she teases.

"No," Alex mumbles, avoiding looking at Emma.

"I saw you when we were here for my 30th. You couldn't take your eyes from my cooch!"

He freezes, a rabbit in the headlights. "That's bollocks!"

"I saw you!" she smiles. "You'd have been staring even more if I'd had my clit piercing in."

His eyes widen and his jaw drops.

"That's right - now you know about six of them," Emma purrs. "Would you like to see all nine?"

"Is this some kind of sick joke?" he hisses, keeping his voice low, not wanting to draw attention. "I mean, what the fuck are you doing?" Then he turns to me. "Are you blind or stupid?"

Emma's surprisingly calm, considering she's trying to seduce her brother in a room full of our families.

"It was all his idea." She squeezes my hand. "I tell him everything, and everyone, I do. He knows everything that happened at my bachelorette." She subtly puts her hand on his thigh - not high enough to rouse suspicion should anyone else see, but enough to rouse his dick. "Everything."

They stare into each other's eyes - Emma's steely assurance answering Alex's questioning glare.

"This isn't a wind up?" he asks.

"I need to feel your big dick inside me, right now," Emma declares.

I'm surprised how loudly she said it. I look around: my parents are ten yards away; Emma's father is on the other side of me, no more than 3 feet away.

Again Alex turns to me. "Is this serious?"

I nod.

Emma says to me: "Take him to the changing rooms. I'll be there in two minutes."

She disappears into a conversation with someone else I don't know, and I lead Alex out into the corridor. I'm a little surprised he follows without protest.

We enter the home team dressing room, and a history of mixed feelings rush back at me. This was where I fled to after watching Emma accept The Ex-Boyfriend's marriage proposal; but it was also where Emma and I conceived our child just minutes later.

Oblivious to my memories, Alex paces around like a caged lion. Despite my excitement, I try to radiate calm.

"This is fucked up. Seriously, this is just plain wrong," he grumbles.

"Why?" I ask.

"Why?!" he repeats, incredulous. "She's my sister!"

"So?"

He stares at me like I'm out of my mind, and continues pacing.

"You'd fuck her if she wasn't your sister, wouldn't you?"

He stops. I can see the turmoil.

He looks like he's about to bottle it. Emma had better get here soon...

She bustles through the door, locking it behind her. Then, with a wicked grin, unlocks it again.

"Get undressed," she orders. "Both of you."

I do as she says.

Alex hesitates. "We can't do..."

His protests stop as Emma's dress hits the floor. Naked but for her white thigh-high boots, she looks spectacular. I can see Alex drinking in every curve, every piercing, every tattoo... and then his eyes fix on her waxed, wet, pierced pussy.

She's been becoming more and more of an exhibitionist, but seeing the effect she has on her own brother really lights her up.

"So, now you can see all nine," she grins. "Do you want to pick where my tenth will be?" She tickles her pussy lips suggestively.

"You're crazy," he mumbles, almost fearful of the embodiment of sex that his elder sister has turned into.

"No, I'm horny." She whispers, edging closer to him. "You can pierce me anywhere you like."

This isn't some nerdy virgin here, Alex is a serious cocksmith, yet he's turned into a jabbering mess. He really doesn't seem to know how to deal with Emma.

"How about one on the side of your ear?"

"Hmm, that's a little safe and boring, isn't it?"

As she gets within his personal space, he backs away.

"I'd want it to be somewhere I could see it."

"This isn't a one time thing. You'll be able to see it wherever you put it. Regularly."

He backs into the wall. Emma stops an inch in front of him - not touching him, but he'd have to touch her body to move away.

"Or maybe you want to pick my next tattoo? Get your name inked somewhere intimate..."

She leans forward to kiss him, and he pulls away. She tries again - he's too slow, and their lips touch...

Time stops. I watch as they stare into each other's eyes for the longest time, so close that their noses are almost nudging.

She's challenging him to make the next move - to choose to commit to this, or to stop it.

I can see he wants it, he wants to kiss her. But something's holding him back.

The tension rises, and rises, until it's unbearable.

Something's got to give...

It's Alex. He pulls Emma to him and kisses her hungrily. They're almost frantic, pawing at each other, their lips and tongues mashing and twisting in a frenzy.

I've never seen Emma so desperately passionate. They've lost themselves in erotic rapture.

Against his bulk, Emma seems even more slim and petite than usual. She cries out as he shoves two large fingers into her dripping snatch, and she practically tears his trousers off.

She'd intimated he was big, but I didn't realise how big. Nearly ten inches long, and really really thick. I can hear her moan in anticipation as she struggles to get her hand around it.

He lines his monster up with her slit, and...

"Wait," Emma breathes.

Alex stares at her like she's gone mad. "What!?"

"I want my husband to feel the first time my brother's cock pushes into me too."

She signals to me to sit down on the bench, in Alex's spot. The spot we fucked in at her 30th party.

I obey, my dick sticking straight up in the air expectantly.

She struts over and turns to face away from me, her legs straddling mine. The sight of her perfect butt and the little dimples in her lower back (with the lipstick kiss and tramp stamp tattoos) is glorious. She takes hold of my prick and holds it against her arsehole, and stares at her brother while she forces her sphincter to stretch around my pole.

She moans as she bounces up and down on my dick, taking the full length up her unbelievably tight rectum.

Alex's eyes are locked on his sister's arse accomodating my rod. "What the fuck?!"

Emma sits back and settles onto me, getting comfortable. Or as comfortable as she can be while I'm impaled in her arsehole. "Your sister is a complete fucking slut. The sooner you get used to that idea, the sooner we can all enjoy it. Now come here and let me taste your beautiful cock."

He steps forward in a daze. As soon as it's in range, Emma grabs his python and pulls it to her mouth.

His girth makes it difficult for her, and she strains her jaw to push herself as deep as possible onto his dick. I guess out of habit, he takes her head and helps her, jamming until she gags on his cock.

"This is absolutely fucking mental," he says.

She pulls back and spits on her brother's massive rod. "If it helps, don't think of me as your sister. Just think of me as another one of your skanks."

"Is that what you're doing? Thinking of me as just another guy?"

"No. I'm gonna get off at how naughty it is that I'm gonna have my brother's big dick inside me."

She swallows him again, gripping his arse and fucking her face onto his cock. I'm actually worried she's going to hurt herself.

I guess Alex is too, because he has to forcibly pull away to stop her choking herself. "What the fuck happened to you?!" He's shocked and properly concerned.

"Just hurry up and fuck me before someone comes and finds us." She opens her legs wide and spreads her pussy lips with her fingers.

Obviously deciding to just go with it for now and get his head around it later, he moves his huge member down to her mound and slides it between her labia.

"Do you really want your lips pierced?" he asks.

"If that's what you want. I'll do anything, just stick your big cock inside your sister's slutty little cunt. Go on, do it. Do it! Oooh yeeaAAAHH!"

Being deep in Emma's arsehole, I can feel Alex's dick as it edges inside her too. It's an amazing sensation.

Emma almost crying, she's so happy. "Oh my God, bro, no-one's ever felt this good. We should have been doing this years ago."

Alex pulls back a bit, then jams back into her - and Emma's as surprised as the rest of us as she cums, squirting into the air, soaking all of us. She locks her ankles behind Alex's back to keep him inside as she vibrates on my cock. It takes all my self control not to unload myself.

"Shit, sis, you're a squirter?" Alex is almost laughing.

Emma stares up into his eyes, her body still twitching with little aftershocks. "This is the hottest thing ever. It makes me feel so sexy that even my brother can't say no. Fuck me hard, little bro. Use me."

He begins thrusting, building up the pace.

"Come on, you're not even using all of it!" Emma urges. "I'm the biggest slut you'll ever fuck, make the most of OH FUCK!"

His strokes lengthen, and I can feel their bodies thud together as he gives her all of him.

"That's it!" she cries, and cums again. Alex pauses but Emma begs him, "Don't stop, God, don't stop! Keep goiiinnnnngggg..."

Her orgasm seems to roll on, never ending.

Alex takes one of her breasts in his big right hand and plays with the nipple ring.

"Yeah, twist them. No, hard." She yelps in pain. Another squirt from her dripping pussy. "Yes! Oh God, like that!"

"You like that?" he asks, genuinely unsure.

She seems completely out of control - her body's constantly jerking and trembling, and she's desperate beyond any time I've seen her before.

"Don't worry if I like it. Do whatever you want with my body. It's yours."

The familiar twinge of jealousy hits my heart and my cock simultaneously. But this time it's a little different; a little more taboo, and that makes it even more delicious.

Alex slams into her. I can feel the power from his rugby training like a jackhammer, and I've got Emma as a buffer between us. God knows what she's feeling.

"This is where I got pregnant," Emma tells Alex. "In your seat, minutes after getting engaged to The Ex-Boyfriend, and with my now-husband talking dirty about how much I wanted to fuck you."

I'd been concentrating so hard on not cumming yet, that the momentary distraction of the memory of me impregnating Emma has me spunking in my wife's naughtiest hole. My orgasm's so powerful that I go a little light-headed.

"Oh fuck, he's cumming up my arse! My husband's baby-making juice is filling my arse while my brother's fucking my pregnant cunt." Emma squirts again! She's gonna be severly dehydrated if this carries on much longer.

"I'm getting close," Alex warns.

"Do you want a nephew or a niece? A girl you can turn into a slut, just like her mum? Your cock's so close to her right now..."

"Oh fuck!"

"Oh God... imagine if I was having your baby," she pants.

"I'm cumming!" Alex grunts.

"In my mouth!" Emma urges, and Alex quickly pulls out. His first shot unloads on her stomach; the second hits her on the cheek; but he gets his cockhead in her mouth in time for her to get the rest.

She mewls contentedly as her mouth fills up, and sighs as Alex withdraws his cock. Emma mimes for Alex to take a picture.

"You're fucking kidding me!"

Emma puts her hands together in a begging motion. Disbelieving, Alex nevertheless searches his trousers for his phone.

Emma hurriedly retrieves a pen from my jacket pocket and writes in big black letters on her flat, toned stomach, 'I JUST FUCKED MY BROTHER'.

She gets on her knees in front of Alex, displaying the pool of cum on her pierced tongue, and poses for a few pics.

I am definitely going to have to get copies of those.

Emma swallows her mouthful, and kisses Alex on the cheek.

"Thanks bro. You're amazing."

We all hurry to get dressed. Emma massages the cum on her stomach into her skin, then wipes her cheek clean with a finger and runs it around her pouting mouth.

"Who wants to watch me kiss Dad with bro's cum on my lips?"

Her Dad? I wonder if she'd ever...
