Our parents separated when Holly and I were five. Mom and dad fought over us viciously until some son-of-a-bitch divorce judge split me and my twin sister, I went to dad, she to mom. We were property, like furniture or cars. Dad got the Harley and boy; mom got the Ford and girl. We grew up apart, only occasionally getting the opportunity to be together during summer breaks, or maybe on one of the big holidays. Even though we were twins I really didn’t know her; what she was like, how she thought, what she did. When one of us kids went to visit the other we were almost strangers. We had a ‘take it or leave it’ relationship. I could hang with her or not, it’s not like I missed her most of the time. I really didn’t remember Holly when she was my sister.

We were 2 months past our 18^th birthday when I was sent to spend Christmas with mom and Holly. Dad and his most recent trophy were off screwing at some beach resort so he was glad to dump me on the female side of my family. Since I hadn’t seen them for almost two years Mom was excited to have me near but my sister treated me like an irritant in her busy life. I didn’t know her friends, I didn’t have a part in her world and the only thing she and I had in common was our birthday. To say I was bored would be a total ‘No Duh’.

The third day I was there I overheard Holly screaming into her phone. “What the fuck do you mean you’re not taking me?! Do you know how long we’ve been planning this? Everybody knows we are going together, I can’t go without you, what would our friends think? Don’t you fucking dare back out of this!”

She paused her tirade for a moment, “You did what!? With who!? You’re seeing that slut!? Are you dumping me!? I gave you everything you sonofabitch! I gave it up to you and now you’re telling me to fuck off!?” Holly’s yelling at her boyfriend attracted mom’s attention; she and I went to the front room to watch. Just as she came into view, my sister drew back her arm and threw the phone against the bricks of the fireplace. Plastic parts flew in all directions from the epicenter of the phone explosion, her friends would never call her on that one again.

Holly spun in a circle, eyes wild, hunting for an escape from the devastating call. Her eyes locked on our mother “I fucked him momma! I gave up my virginity to that bastard” she wailed. Tears began to streak her mascara as she fled the room for the sanctuary of her bedroom. For the first time in many years I felt a close bond with my sister. I felt sympathy for her, and surprisingly, anger at the guy that had caused her pain. At that moment I would have gladly smacked him down for her.

My mother glared at me “That’s something your father would do! You ever do that to a girl I’ll cut your balls off and give them to her as a gift.” What the fuck? I was just standing there and all of a sudden I was as bad as Holly’s boyfriend? Mom spun on her heels and went to fuss over her injured child.

I didn’t see my sister for two days, she hid in her room ashamed to face the world. Mom catered to her broken daughter while I played with Holly’s Xbox and help decorate the tree and house hoping to bring a little holiday mood back into the family. Late the second day my sister came out and sat with me in the front room “I’m sorry for my outburst, I shouldn’t have yelled like that. Please don’t tell anybody what I said.”

“What’s that?”

“You know, about him and me and him being my first boyfriend that way.”

“Who am I going to tell Holly? I don’t know any of your friends, mom already knows and it’s none of dad’s business. I’m not about to tell my friends that my sister got fucked over by some sleaze, your secret is safe with me.”

She looked slightly relieved, “Do you think I’m awful? I mean, is it okay with you that I went to bed with a boy?”

I wasn’t sure why she was asking me “You’re my sister, not my girlfriend, what you do in the dark with some guy isn’t for me to worry about. If you want to screw someone until his nuts fall off, have fun, I won’t diss you for something like that.”

My sister flashed a smile of complete relief, dimples dented her cheeks. “Have you had sex yet?”

“With a girl?”

She looked slightly puzzled. “Are you gay?”

“Jesus, do I look gay? That’s repulsive, you may like boys, but I sure don’t. It’s only big tits and fine asses for me.”

“You didn’t answer me.”

I didn’t want to admit to my sister that I’d managed to seduce three girls. Even though she had spilled her secrets when she got dumped I wasn’t one of those guys who brags endlessly about his conquests. I felt myself blushing as the truth got trapped in my throat. I didn’t have to say the words, Holly saw the answer in my reaction, “It’s okay, you can talk about it, most boys do, how many?”

“Three” I flustered.

“Are they pretty, do they have big tits and fine asses?” my sister teased mischievously.

I changed the subject “Are you still going to your friend’s Christmas Eve party?” That was the big event she was supposed to go to before her beau dumped her.

“I don’t know, it’s for couples only. There are some guys I can ask, I can’t go alone.”

The next day my sister flounced into the house in a pissy mood. “Mom! Where are you?”

Our mother called back, “Doing laundry, why are you shouting?”

Holly was raging “Because Chad and Rich won’t go with me to Sharon’s party! That motherfucker put out the word that nobody should go to the party with me! I don’t have a goddamn date and I can’t go alone! Assholes! All of them!“

The house was quiet for a few moments, my sister was taking off her coat when mom came into the room “Please control your language girl; you can take Lee, I’m sure he wouldn’t mind getting out and mixing with your friends.”

Holly shot mom a withering look then moved her eyes to me “Him? What would everybody think if I showed up with my brother on my arm?”

“Do your friends know your him? Have any of them ever seen him?”

“Maybe a really long time ago, why?”

“Who’s to know he’s your twin if you don’t tell them. He’ll be the mystery boy, the new kid and your friends will be bubbling over with curiosity about him. Look at him, he’s handsome, tall, athletic, you could do a lot worse for an emergency date.”

I sat in my chair and listened to my mother and sister bargain over me as if I were a nick-knack at a yard sale, “But he’s my brother” protested Holly.

“So don’t make a pass at him, you don’t have to take him to bed” mother joked.

My sister finally looked my direction, resignation clouding her hazel eyes “You want to go to Sharon’s Christmas party with me?”

I got caught up in my mother’s teasing mood “As your date? Only if you promise not to fondle private parts of me.”

She bristled “Then what the hell should I fondle, only non-private parts?” Having fired that angry broadside Holly tromped quickly out of the room. Mom chuckled softly and winked at me, a conspiratorial wink. I had just seen a playful side of my mother, apparently she wasn’t afraid to get personal or talk about taboo subjects with her children.

Holly briefed me on the upcoming holiday fest and her friends and the more she talked the better we both felt about me going with her. Nobody knew we were related so she wouldn’t suffer that indignity and I was looking forward to meeting some of her friends. My sister was hot looking so I knew I’d meet some more hot looking babes.

She was wearing an elf costume. Green jacket with white faux fur collar over a very short green skirt that had white fur around the hem. Candy cane leotards covered her legs from the top of black patent ankle boots. Her ash blonde hair that normally fell half way down her back was pulled into a pony tail that hung from under a floppy pointed elf cap, multi-hued glitter twinkled over hazel eyes. The jacket was open in a deep vee, showing a lot of fresh firm cleavage; cleavage that sparkled with a light sprinkle of silver glitter. She wore Christmas tree bangles from her ears and a necklace that looked like a small present hanging from a red ribbon. For the first time in my life my twin sister attracted my male attention. She was sexy!

It was when I walked into Sharon’s house that my testosterone really began to boil. Many of Holly’s friends were already there so the big room was full of Santa’s little helpers, most of them dressed in some variance of an elf costume. There was a forest of shapely female legs topped by short skirts and several degrees of breast exposure. My sister dragged me around the room by a hand introducing me to her friends. One girl, Jill, sent shivers up my spine, she was small, maybe 5’1’ but the dark eyed elf was cuter than any girl I’d ever dreamed of meeting. Since this was a couple’s only party there were as many guys as girls.

As we stepped away from her friends Holly muttered under her breath “Son-of-a-bitch!”

“What?”

“There he is with that fucking slut!” I looked at the front door as her ex-boyfriend came into the room with a moderately attractive girl holding his hand, the boy looked surprised to see Holly. My sister shot him a death ray stare then grabbed my arm and led me to another room. I was bigger than him so I knew he wouldn’t make any trouble.

Holly let go of me then scurried off to do girl talk. I was the tall dark stranger in the room so I attracted several coy glances from girls but most of the boys openly glared at me, the interloper. Holly was the only one I knew so I went to find her. “Hey, you can’t just abandon me right now.”

“I didn’t abandon you, why not?”

“Because I don’t know anybody here, I think the soccer team over there wants to kick me to the goal and I can’t talk to any girls because they all have dates.”

“Shit – okay, let’s get something to eat.”

The party moved past the warm up phase. We listened to holiday tunes, exchanged small gifts, sang Christmas songs and some guy dressed like the Grinch recited The Night Before Christmas. The ex-boy friend must have gotten bored or horny because he and his ‘fucking slut’ left the house early. I noticed several of the partiers slide out the side door and come back a few minutes later, Holly included. On her second trip outside she invited me along. We walked around the back of the house where someone handed my sister a plastic tumbler with a gin and cranberry mix in it. She took a couple of sips then handed me the glass. I finished the drink then we asked for a rum soaked eggnog. My sister and I finished that concoction while talking to another couple then took another drink into the house.

The party was getting livelier, the mood more festive. I tried hitting on Jill when her goofy looking boyfriend went outside but Holly pulled me away “You can’t be like that tonight, you could ruin it for both of us if you start sniffing up any skirt but mine. What would everybody think if my new boyfriend was trying to cheat on me at a party?”

“But I’m not your boyfriend” I reminded her.

“Nobody else knows that. Right now you’re my date, you have to act like it, I don’t want to have to explain why you don’t like me.”

“I like you fine.”

“You know what I mean, like me like a girlfriend.”

I had just enough alcohol induced bravado to treat her as she wanted. I looked around the room and spotted what I was looking for, “Come with me.” I grabbed Holly’s elbow and towed her to the large chandelier that hung at the center of the room, when I stopped I pointed toward the lights. Holly looked up at a big sprig of mistletoe, she dropped her eyes to mine and started to say something but I wouldn’t let her. I leaned down and kissed her squarely on the mouth. She jerked back from me and stared at me with astonished eyes, embarrassment rising in her cheeks “What the hell was that?”

“It was a kiss, just like this one” I grabbed her shoulders and planted my lips on hers again and kissed her hard. She tried to say something but the words were muffled by my mouth over hers. I lifted my lips off hers and looked around. My little show had attracted the attention of several of her friends “There you go, now everybody thinks I have the hots for you.”

She briefly studied my eyes, glanced around at the inquisitive faces then began to smile. Holly stepped nearer, put her arms around my neck and pulled me down for a more tender, lingering kiss. As her lips moved against mine I felt her ease closer me so her breasts were pressed against my chest. I put my hands on her waist and held her while our noses rubbed together. My cock stirred in my shorts.

We stopped abusing the other’s lips and went outside to get another eggnog then Holly pulled me into a shadow where we could talk privately.

“I’m glad you did that for me.”

“What?”

“The kissing, now everybody knows that I’m not crying about getting dumped by the asshole, they know I’m not a reject girlfriend.” We were sitting in a yard swing so she slipped her hand into mine, “You know what?” she said bashfully “I forgot for a moment I was kissing, uh--, you know, -- you. It was almost like real when we did it.”

I knew exactly what she meant. “Maybe because I’m only your occasional brother. Most of the time we are more like strangers than related.”

“Well,” she said with finality, “for the rest of the night you’re not my occasional brother, you are definitely my date.” She pecked me quickly on the mouth then finished her drink in one long gulp “Let’s go back.” I watched her legs and butt as she walked ahead of me, my cock took a breath of new life. Just as we entered the house she spun to face me and asked playfully “Were you just watching my ass?”

I confessed “Yeah.”

Holly turned away from me again while looking over her shoulder, she twitched her hips slightly making the short skirt rock provocatively, dimples dotted cherry colored cheeks, her eyes sparked impishly, “Fine isn’t it.”

The supply of rum eggnog helped the party get more intimate. After the first kiss Holly wasn’t being shy about showing her friends that we were a couple, she would occasionally caress my arms or body and we even kissed lightly a few times as we mingled with the others. She didn’t protest when I caressed her from shoulders to ass a couple of times. The more attention she paid to me, the more I became accepted by her friends, even the guys. She was also slowing charging my sexual batteries.

We were playing musical chairs, the boys were sitting back to back on dining room chairs and the girls were circling as the music played. When the music stopped the girls fought for a lap to sit on only they didn’t sit with their backs to the boys, they straddled legs and sat face to face with us. Since all the girls were wearing short skirts, there was a lot of flashing legs, close groin contact and growing erections. I had several girls rubbing their legs on mine including my wet-dream Jill.

There were two girls left to fight over the last place to sit which was my lap. The music stopped and Holly scrambled to mount me while trying to fend off another pretty blonde. When the playful cat-fight ended my sister was sitting on my thighs smiling triumphantly. She put her arms around my neck and said “Merry Christmas sweetheart, I won, you’re my gift” then kissed me hotly while rocking her hips, crushing my hard-on with her weight. I slipped my hands under her skirt and held her firmly as the tips of our tongues flirted briefly. The room broke out in whistles, cheers and applause while my festive date chafed her crotch on the rigid bulge in my lap. My arousal was evident when I got off the chair but I wasn’t embarrassed, several of the guys were sporting woodies and the girls were teasing us about them. My sister checked my groin then blushed red but smiled coyly at me when she realized she had caused her brother to get so fucking turned on.
