A/N -- Thanks for the positive feedback regarding this story so far. I wasn't sure how it would be received, so I'll admit to being pleasantly surprised so far. Despite it turning into a 'harem', I still like to provide a romantic edge, even if characters are sleeping with multiple partners. In the end, this is all fantasy and supposed to be good fun!

*****

Deborah

She felt the smile form immediately as she woke up, trying not to move as she first saw brunette hair then a forehead in front of her face, looking down to see her twin sister still fast asleep, snuggling into her body. Tightening her arms around her a little, she felt Katie shuffle, getting comfortable while still fast asleep.

It might be Christmas Day, but she wasn't in a hurry to get up. The days of waking up early to open presents had disappeared long ago. While the family did buy each other gifts, they were generally smaller things rather than the million and a half presents they received when they were children. As most of them were adults, it was more about spending the day together, gorging yourself on food, drinking yourself silly, and just enjoying yourself.

Still, she did have a gift on Christmas Eve from her sister. The only other person in the house who knew they slept together was their mother, and the only reason she knew was that she'd walked in on them when they'd started to fool around. What surprised both of them was the fact their mother didn't freak the fuck out and kick them out of home. Just like with her brother and Heidi, she sat them down, warned them of the dangers, asked them to keep it private from everyone else, but if they wished to show their love by being intimate, so be it. They were adults and knew the consequences.

The twins had shared a bedroom for years, only separating during their latter teenage years when they wanted more privacy. But even then, Katie or herself would still end up spending most of their time in the bedroom of the other. Deborah would admit she'd been the one to make the move on her sister that first time they were intimate. Her heart had been beating furiously when she bit the bullet and kissed her. To her surprise, Katie didn't recoil in horror. When her twin kissed her back, Deborah nearly cried. When they parted and stared at each other, Katie smiled. "Been waiting for you to do that," she'd said.

"Really?"

"Debbie, you're my twin sister. Think I don't know what you're thinking?"

"But... you're seriously okay with this?"

Katie proved she was okay by kissing her. Kissing led to them ending up on the bed together. That led to clothing being removed and hands exploring naked bodies. That led to bras and panties being removed, fingers finding wet places to reside, mouths and tongues exploring other parts of their bodies. Deborah had always considered herself a little bisexual, though only for particular women in her life. And that first time she devoured the pussy of her twin sister, and she made Katie moan, whimper and beg for an orgasm, she knew they would continue doing this for as long as they could.

Then Katie returned the favour, and for the first time she could remember, she nearly cried during and after sex. Most of the time, she just liked being fucked, but being intimate with her sister was a whole other thing entirely. Neither were virgins, though she figured to having a little more experience than Katie, but if she'd never eaten pussy before, Deborah would have been surprised considering she had one of the best orgasms of her life.

That was four years ago. Since then, they might have had the occasional boyfriend or friend with benefits, but the twins couldn't resist each other. More than once a week, they'd end up in bed together, eager to use mouth and fingers on the other, desperate to make their twin orgasm over and over again. Sometimes, they'd just want a quickie. Other times, they'd make love for hours, until they were exhausted, drenched in sweat, barely able to stand up.

Their mother discovered them within three months. The twins tried to be quiet when fooling around, but their mother would know when people were having sex in the house. The sounds were unique. Thankfully, all she did was open the door to find them enjoying one hell of a good sixty-nine. Both girls freaked out, their mother simply smiling, stating they would talk in the morning.

Once it was accepted by their mother, there was no stopping them. And they shared particular days. Katie's birthday, Deborah ate her pussy whenever she could. Deborah's birthday, Katie returned the favour. Australian Day, drinks, barbeque, sixty-nine. ANZAC Day, pay their respects with two finger salutes into each other's pussy. Christmas Day, they would have some of the best sex of the year the night before. New Years Eve was the only day and night which was a struggle to do something. And, of course, the anniversary of their first time being intimate was always a special night. Their mother figured that out quite quickly too, thinking it was rather sweet.

"Katie," she whispered, her sister slowing stirring. Watching her eyelids flutter open, meeting her eyes, the smile was immediate and infectious.

"Debbie, you ruined me last night."

"Well, I seem to remember you asking me to make you cum harder than you had in your life. And as I love to do what my sister asks of me..."

"I love you."

Deborah kissed her softly on the lips, caressing her cheek, their noses almost touching. "Love you too, beautiful."

Katie snuggled into her. "Guess we'll have to get up soon. God, if Mark found out we fooled around..."

"He won't freak, trust me on that. I think he'd want to join in."

"You'd want him to join in, Debbie."

"Katie, come on, you're just like the rest of us..."

"I know you want him, Debbie, but..." She lifted her eyes and sighed. "Confession for my sins?"

Deborah felt her eyebrows rise. "What?"

"I'd feel like I was cheating on you."

"But... Katie... we've been in relationships and..."

"Debbie, you've always been the more important. I slept with them as cover for the fact I wanted to be with you more than anything." Resting her head against her chest, Deborah caressed her back as Katie started to shake slightly. "Confession two," she whispered, taking a deep breath, "He's old enough now... I can admit it too..."

"You want to be intimate with him?"

Katie lifted her eyes to hers, Deborah feeling her heart ache at the tears. Lifting a hand to wipe them away, she asked, "Is it that bad?" Katie nodded. "You really want to be intimate with him?"

"As much as you do," she whispered, her breath shuddering.

Deborah leaned down to her ear. "And he'd love it with you too. My twin is an absolute sweetheart. And she's even better in bed than most men I've been with."

"It's because I love you so much, Debbie. And you make me feel just as good in return. God, I still remember that first time you went down on me. I had to stop myself crying the entire time."

"Katie, you're still the only one to make me cry when I orgasmed. The only other one who'll do that to me is Mark when I finally get my claws into him. I hope he makes me cum so hard, I pass out on him. Might freak him out a bit."

That made Katie laugh, which made her laugh, the pair hugging tightly. A knock at the door led to that stopping, their mother poking her head through the gap. The smile and eyes were of love and approval at what she saw. "Everyone is getting up, girls. Might want to get ready yourselves. Amy and I are cooking up a storm right now."

"Thanks, Mum," Deborah stated.

"Have a good Christmas Eve?"

"We did, Mum. It was wonderful."

"Good. I liked the video you sent me too. I may have masturbated to it."

Katie started giggling again. "I can't believe our own mother..."

"Watching my twin daughters make love is beautiful, erotic, and a real turn on."

"Yeah, we're all a little fucked up," Deborah said with humour.

"Maybe, but I can see the love being shared. So, I live with a smile on my face. Anyway, breakfast will be served shortly."

"I'll get up," Katie said, leaving one last, lingering kiss on her lips before she got up, throwing on her thin vest and very short shorts before following her mother out the door. Deborah lay back, spreading her legs slightly, not surprised to feel she was wet. Just holding her sister in her arms turned her. Hearing her mother masturbated to their video sent a real shiver up her spine. As far as she knew, no-one had been intimate with her mother. She didn't think Sandra or Becca had been fun with her. She wasn't sure her mother even had lesbian tendencies. Watching her daughters have sex didn't mean she wanted to be with a woman.

Though a Christmas morning orgasm did sound nice, her stomach rumbled and that made her decision. Throwing on a pair of thin panties that barely covered her arse, and a vest that showed off her flat stomach and belly button, she wandered out into the kitchen, Amy and her mother busy cooking. Amy looked her way and almost rolled her eyes.

"You know, I should be used to it after all this time, but it's gotten worse since he turned eighteen," Amy said.

"Look, if he just threw me on the table and wanted to eat my pussy or fuck me, I wouldn't stop him," she retorted, "Did he spend the night with Heidi?"

"I think so. Wasn't with me. My dildo got a nice work out instead. Had to get a bigger one after he fucked me, simply so it felt about the same."

Her mother chuckled. "How casually you discuss such matters nowadays."

Katie reappeared within a couple of minutes, taking a seat next to her twin, the pair sharing a glance and smiling. Kelly and Simone appeared together, the former looking rather flushed. Deborah couldn't help staring as the flush was obvious. Before she could even ask, Kelly said, "Heard them last night. Just had to close my eyes and make myself cum time and again, thinking it was me."

"Gagging for it?" she asked.

"He notices all of us, but I understand why his attention is being taken for now. But, yeah, I need a deep dicking from my cousin." Simone snorted before bursting into laughter. "So do you, little sister."

"You think?"

"Simone, you're gorgeous," Deborah replied, "Trust me, he finds all of us attractive and desirable. It's probably sensory overload for the poor guy at times, all six of us giving him the eye, almost pleading with him to fuck us."

Her mother cleared her throat. "Girls, just remember your grandparents will be here for lunch and the afternoon, so you'll have to behave while they're here. I've already warned them about Mark and Heidi, and they accept that without a problem. But some of the other shenanigans you've been up to this week will shock them and they're not as open-minded as my sisters and I."

"Talking about Mum and Dad visiting?" Sandra asked, appearing at the doorway.

"Just warning the kids to be careful."

Sandra looked straight at Deborah, which made her laugh. "I'll behave, Auntie."

Heidi and Mark appeared hand in hand a little later, just as breakfast was being served up by Amy and her mother. There was no doubt Heidi had been given what she would called 'the treatment' the night before. Her smile was simply dazzling, and the look in her eyes as she gazed at Mark whenever he spoke, Deborah recognised when someone was falling hopelessly in love.

"Good night, Heidi?" she had to ask. Heidi blushed and nodded. "Eat your pussy again?" Her mother sighed but with a smile. "What, I'm getting it out of my system before Nan and Pop arrive."

Everyone looked at Heidi. "I've never cum so hard in my life," she gushed, "He must have eaten my pussy for hours."

"Sore jaw this morning?" Katie wondered.

Mark grinned. "It was a little sore last night once she said enough. Didn't think she could take me making love to her, so I... er... um..."

"He jerked off onto my body," Heidi said, chuckling away, "Felt so naughty, and he came so much!"

Sandra burst into laughter. "What we discuss at the table nowadays."

"I love it considering my love life is rather barren right now," Rebecca added, "And considering my daughter is the one being pleased, I can only sit here and smile."

Thankfully for most, the conversation did move onto more mundane topics, before they carried mugs of coffee or tea into the enormous living room, gathering around on the comfortable lounges, as small presents were handed out. Mark had insisted since he started working that he didn't need all that much, but he did go out of his way to buy something for all the women in the house. He didn't always get it right, but it was the thought that counted.

Deborah handed him an envelope, no doubt expecting to find some sort of giftcard inside. Instead, he found a small booklet she'd made. If he had any doubts as to what she wanted from him, his eyes lit up as he read what she'd offered him. "You're serious, Debs?" he asked, looking at her with that sort of smile that had them all grinning in return.

"Solo blowjob will just be by myself. Twin blowjob will be me and Heidi, as she needs to learn. Sex is just what it says. Some gentle love making, some really hard fucking. Anal sex is something I know you haven't done and I'm fairly sure most of the others around here are not particularly interested. If you are, then we have things to talk about! And the question mark cards are something I'll have to tell you in private."

"Wish I'd thought of that," Amy muttered, giving her sister a gentle bump to show it was in humour.

"You can redeem them whenever you want, Mark. If you want the dual blowjob, you'll just need to make sure Heidi is around."

"Is it just me, or do you really want to see her blow him now?" Katie wondered aloud.

"Girls, as I said earlier, not yet. Wait until your grandparents have been and gone."

"Actually, Caroline," Sandra stated, checking her watch, "They won't be here for another hour or so."

"My daughter waxes lyrical about his cock. Are you not at least a little bit intrigued?" Rebecca added.

Her mother chuckled. "God, we are definitely a weird bunch," she muttered, before she sighed, "Fine, Deborah, if your brother wants to..."

He ripped one of the pages for a blowjob and handed it to her before their mother could finish her sentence, earning plenty of giggles from the others. She rose to her feet and stood in front of him, taking off her vest to reveal her breasts, watching his face light up, before she lowered her panties, revealing her pussy, where the strip had been joined by a little more hair. She was aware Heidi had shaved herself for their first time, but to her surprise, Mark said he didn't mind either way, but knew shaving could be a pain at times.

Straddling his lap, she felt his strong hands immediately on her back, leaning down to finally kiss him. And her brother proved within seconds that he was an incredible kisser! Enough that he provoked a whimper of desire, particularly as she could feel his hard cock beneath his shorts. "Little brother, I do think you have a big surprise for me in return," she cooed.

Kissing him softly again, she slid off his lap onto the floor as he removed his shirt, reaching up to the band of his shorts and helping them off, revealing his thick, hard cock.

"My god," Sandra muttered.

"Holy shit, he's fucking hung!" Kelly exclaimed.

"I'm about to watch one of my daughters blow my son," her mother said, glancing to see a smile on her face, "And I can see why Heidi is always smiling. You too, Amy. More than once, right?"

"Heidi is remarkably understanding for a young woman."

Grabbing the base of his cock, Deborah ran her tongue from the base to the tip, earning an immediate groan from him. "Don't cum too fast," she said.

"I'll try, but first blowjob and all..."

"Well, if you do cum quickly, I'll just keep sucking you until you cum again."

"Okay, this is already, like, really hot," Heidi said.

Deborah glanced at her. "Watch and learn, Heidi, but we'll do it together soon. He'll think all his birthdays have come at once with two women sucking his cock."

She licked his cock up and down, just savouring the rather smooth texture, teasing the head and making him groan again, before moving down and giving his balls some attention, which made him shudder, provoking the sort of reaction that made her smile. She continually looked up as he gazed at her in return, looking rather dazed.

But she wanted him in her mouth, and knew that teasing him would just make him cum quickly. Lowering her mouth around the head of his cock, she almost moaned at how thick it was. For an eighteen-year-old man, he'd been given one hell of a gift. Good thing she could deepthroat, though that would be for later. This was just about tasting his cock and his cum.

As he did sit there rather dazed, she grabbed his right hand, ensuring he caressed her hair as her head started to bob up and down on his cock. She did enjoy the fact he was still rather inexperienced, pleased that she might get to show him a few things. And if she could show Heidi too, perhaps Heidi might be interested in other things herself. She'd proven very open-minded already.

"Deborah," her brother moaned.

"I'm not sure if I should say this is beautiful, erotic, or one of the hottest things I've watched," Sandra stated.

"I'm wet watching, I don't care who knows," Amy added.

Deborah took a little more of his cock with every passing minute until she reached the point where she couldn't without it going down her throat. But considering the look on his face, the way he was breathing, and the look in his eyes, she knew his orgasm was imminent. He probably didn't even realise it yet.

Eager to bring it forward, she bobbed her head up and down quickly, her tongue hard at work at the same time, using one of her hands to caress his balls at the same time. "Oh god!" he cried.

"Cum for her, Mark. Cum for my sister," Katie whispered next to him.

"Oh god," he groaned again, "Debo..."

Then he came, Deborah almost choking as that first spurt did catch her by surprise. She gulped that down immediately, her mouth soon filled by even more of his cum. She moaned as she swallowed, not putting it on. Her brother tasted divine, thinking he did have a good diet. She'd swallowed other men who tasted awful compared to him. He must have spurted six good sized doses before he had nothing left, Deborah continuing to slowly lower her mouth up and down his cock until she finally let it pop out of her mouth.

What surprised her was the fact she was hauled off the floor, Mark wrapping her in a tight hug. He didn't say anything, Deborah resting her head against his shoulder. "Thank you," he whispered, hearing his voice a little heavy with emotion.

"Good?"

"Better. Much, much better than just good."

There was a sniffle, leaning back to see her mother wiping her eyes, before she chuckled. "Sorry, but... I can't sit here and watch that, then think there was something wrong with it. Deborah, that was just... wonderful. And you made my son... happy."

"More than that, Mum. I think the word is euphoric."

"Make love," their mother said, "I know you want to, Deborah. Make love to your brother."

"You sure?" Mark asked.

"Please. For me. For all of us."

"Heidi?" Deborah asked.

"Trust me, I probably won't be the only one masturbating considering the look on some faces in this room," she replied.

"Mark?" she asked softly. He nodded eagerly, so it was a rather simple process of lifting herself up, aiming his cock, and she ever so slowly lowered herself down it. When she bottomed out on it, she needed a couple of moments for herself, resting her head on his shoulder again. "Oh my god, Mark," she moaned, "Your cock is... magnificent."

Resting her hands on his shoulders, all she wanted to do was ride him until she had an orgasm, and considering how great it felt inside her, she knew that wasn't going to take long. Feeling his hands holding her by her hips, she wasted no time bouncing up and down on his cock, and was pleased when he wasted no time sucking one of her breasts. Mentioning that he'd always loved her breasts, he just looked up and grinned.
