It's Katie

The biker's voice was muffled by the helmet, but it was unmistakably feminine. Even then it is still a surprise when the black helmet is removed to reveal a truly gorgeous blonde. Her golden hair is currently tied up in a sensible pony tail to prevent accidents whilst riding the powerful motorcycle. Her bright, electric blue eyes dart from Rachel to yourself, and her gaze meets your own. The tight leather outfit betrays the fact that she has an extremely curvy body with a huge pair of breasts that rival even Rachel's immense set of knockers. 

"Hi, Katie. It has been a long time. How are you?" Rachel finally replies. Her expression shows uncertainty and discomfort.

"Yeah, I'm good, thanks! Work and University are keeping me busy. You look terrific by the way!" Katie says warmly, flashing Rachel a dazzling smile as she hangs the helmet on the bike's  handle bars. 

"So this must be, John?" Katie asks, while dismounting the bike. The simple action of getting off the bike gives you a great view of her leather clad  posterior. The skin tight trousers leaves you in no doubt that Katie has a bubble butt that would make a centre fold model jealous, and is in a similar league to Rachel's own incredible bottom.

"Yeah, I guess I must be. It's nice to finally meet you, Katie. Rachel has said only nice things about you". You say sincerely, ensuring that your eyes are addressing her face, rather than roaming over her leather clad body.

"Likewise. Rach, you weren't lying when you said he was a hunk". Katie says, flashing you a flirty smile in an attempt to make both Rachel and yourself feel awkward. From Rachel's body language it is evident that it had worked on your girlfriend.

" Katie, Rachel says that you're at University studying to be an architect". You state, moving the subject onto the leather clad blonde.

"Yeah, that's right". Katie replies while pulling her hair out of the pony tail, allowing her long golden hair to fall all the way to the small of her back.

"I'm just wondering how on earth you can afford this bike. It's the latest model of the Triumph line, and is less than a few months old". You continue, running your eye across the sleek lines of the bike.

"You know your machines, mister. I'm impressed. Are you a biker, John?" Katie asks, her beautiful face lit up in an approving smile. 

"I like them, but I don't own one. I was tempted to get one a couple of years ago, but I felt I was far too young for a midlife crisis, and opted for a fancy car". You reply. Your eyes dip from her face to her crotch, and you are certain than you can see a discrete bulge in Katie's tight leather trousers.

"Is that the beauty of a car parked outside Harvey and Sarah's house I saw on the way down here?" he busty blonde asks, which you reply to with a nod. "Looks like you moved in with the right guy, Rachel! I'm surprised that you haven't told him about my part time job though". She adds while favouring Rachel a knowing smile. 

"Oh? Do I want to know?" You ask, raising an eyebrow at your girlfriend.

"Well... she's a model". Rachel says finally. The long pause makes you suspect that there is more to Katie's job than what has been said. Of course Katie's lewd smile, and Rachel's blushing prove to be not very subtle indicators too!

"Speaking of which, I need to get out of these leathers!" Katie declares while removing her gloves. "Can you please hold onto these, John? Thanks". The busty blonde says as she hands you the gloves. The next article of clothing to go is the leather jacket. Unlike the gloves, Katie takes her time with removing the jacket. She slowly pulls down the zip revealing a red dress with a plunging neckline. To avoid the accusation of ogling another woman you reluctantly avert your eyes from the blonde to your girlfriend. Rachel's gaze is drawn to her friend's full breasts, before she finally notices that you've caught her ogling Katie's tits. Her cheeks redden, and she offers you an embarssed little smile.

After flashing your lover an affectionate smile, and an coughing sound from Katie you turn your attention back to the busty blonde. She doesn't seem annoyed in being ignored during her little show, in fact she seems quite amused if that little grin forming on her lips is any indication. Her leather jacket is currently hanging over her bike's handle bars.

Once she is satisfied that she has her audience's attention again Katie lifts up the seat of the bike to reveal a small storage compartment with a pair of black high heeled shoes in them. She picks them up, places them on the ground next to her, and begins to work her way out of her left calf length boot, before moving onto the other.

With her boots and socks off, revealing that she has a fresh coat of red nail polish on her toes, the busty blonde unbuckles the clasp of her tight leather trousers and slowly pulls the garment down. It seems to take an eternity for her to pull the trousers over her full bubble butt, down her long legs until they are down by her ankles. With a practised elegance Katie steps out of the trousers, allowing you to fully appreciate her dress. With the exception of the black trim it is a lot like Rachel's garment, showing off the blonde's long tanned legs.

"Sorry Rachel, you should of told me that you were wearing red!" Katie jokes, acknowledging the similarities off their clothing, whilst stepping into the high heels. Rachel's long time friend flashes a lewd wink at you before bending over to tie up the straps on the shoes, thrusting her full behind into your face. The short length of the dress is barely covering her bubble butt.

A sharp intake of breath from Rachel somehow draws your eyes from the softly shaking sweet cheeks right in front of you. Your girlfriend has been given a spectacular view of Katie's huge breasts with the blonde bent over in front of her. The lustful grimace on Rachel's beautiful face, and the way she is shamelessly ogling her friend's tits, only encourages you to check out the end that Katie is displaying for yourself.

"Enjoying the view?" Katie purrs rhetorically. She could be asking the question to either Rachel and yourself, so you reluctantly tear your eyes from her jiggling bottom to her face. She is looking back at you over her shoulder with a smouldering pout. Her gaze drops to your crotch, or more accurately the bulge protruding from your trousers. Her lips twist into a lewd grin as her eyes lock with yours as she reaches behind her, and lifts up the back of her dress revealing a racy pair of panties utterly failing to conceal the firm, full cheeks of her heart shaped ass. The missed opportunity of fooling around in Rachel's room earlier, coupled with Katie's booty on full display has resulted in your bulge to become a full on tent in your trousers, something which Katie seems to appreciate if the lustful twinkle in her eyes is any indication.

"Well, this won't do! Let's go to the party!" Katie announces, suddenly standing up straight, and smiling mischeviously at the frustrated moans made by Rachel and yourself. "I'm going to see the birthday girl and get a drink. Come inside when you two have cooled down a bit!" Katie adds with a wink. She scoops up her discarded leathers, folds them, before putting into a carrier bag in the compartment and makes her way towards the function room building. A quick glance to Rachel reveals that she's watching the blonde's swaying behind every step of the way.

"Hey! I'm right here you know!" You joke, causing her to jump.

"Sorry". She says with an embarrassed smile, knowing that she's been caught again.

"Don't be". You assure her, before wrapping your arms around her narrow waist, pulling her tight to you and kiss her ferociously. 

"John!" She whispers, before kissing you back with the same level of intensity. Her huge breasts mash themselves up against your chest, while her cock brushes up against your thigh.

"So then". You whisper, after finally parting lips from Rachel. "Tell me about her job".

Rachel blushes. "She, er works for a site. As a... web cam model".

"Oh?" Is all you can say. It is a few moments before you continue. "I take it is an 'adult' site?"

"Yeah, she falls into the 'fetish' category on the site. She's a 'premium model', and her rates are high. Her shows really are something else. Or so I've heard..." Rachel adds with an embarassed little smile.

"And where did you hear that from?" You ask with a smirk. 

 "On the reviews on the site obviously!" She replies a little too quickly, leading you to suspect that she's used the site in the past to watch her friend 'perform'. "It's getting cold out here. Can we go inside?"

"Sure". You reply while slipping your hand into hers. As you make your way to the front door of the function room. "Say, Rachel..."

"Yeah, John?" Rachel asks, her beautiful eyes sparkling with love for you.

"I can't help but notice that Katie, Amy and yourself are all quite....busty. Is it a coincidence. Or is it genetic?" You ask awkwardly, wishing that you had worded your question better.

Rachel's beautiful face lights up in a amused smile. "I thought that you had missed that trait we share". She teases you with a wink. "The doctors don't know why, but all hermaphrodites who were born as a result of those fertility drugs developed really large breasts once puberty started. I have to admit that I thought it was another part of my 'curse': my boobs would attract all the guys, but I couldn't get close to them because of my 'secret'". She admits, with a sad reflective smile that threatens to tear at your heart, as she opens the door.

"I wonder if they all enjoy getting their ass fucked quite as much as you do!" You murmur, as the pair of you enter the function room.

"John!" Rachel shrills, sharply jabbing you in the ribs while looking around for anyone who overheard your remark.

Two girlish voices giggle to your immediate right "Rachel, you slut!" Amy giggles as she emerges from the cloak room, immediately followed by Katie. Rachel's face turns a bright shade of beetroot as a result of her baby sister, and best friend overhearing about her fondness of anal sex, and she struggles for a response.

"Dad's getting the first round in. Go up to the bar to tell him what you two want". Amy informs the pair of you with a lewd smirk on her beautiful face which is almost identical to her blushing elder sister........

...............................................

The next few hours are spent getting to know more of Rachel and Amy's family and friends. Rachel had previously told you that she kept to herself during school, and had very few close friends, but it appears from speaking to Harvey during the night that the opposite was the case for the younger daughter. Lots of guys and girls her age were present, drinking, dancing and generally having a great time. While Rachel had been more reserved growing up, Amy was more outgoing, and more often than not out with friends. 

"I'm just going to the ladies, John". Rachel says, getting out of her seat, before planting a quick kiss on your cheek.

"Do you want me to come with?" You ask with a wolfish smile.

"I do, but it probably isn't a good idea for you to fulfill the promise you made in the restaurant last week!" Rachel purrs in your ear, before swiftly turning on her heels leaving you alone at the small table with a smile on your face.

Your phone gently vibrates in your pocket. Once you retrieve it from your pocket, and glance at the screen your smile returns as you see that you have a text from Rachel.

"The cubicles are a little bit cramped for what I want you to do to me ;) In fact I can't wait much longer. In a few minutes I'll come out pretending to be drunk, and you escort me home ;) xx"

"Sounds like a plan, my little slut ;) xx" You message back instantaneously.

"Do you mind if I join you?" A soft feminine voice says into your ear, causing you to nearly jump out of your seat.

"Christ!" You exclaim.

"Sorry, John!" Katie apologises with a giggle at your reaction to her sneaking up on you.

"It's alright. Please sit". You reply, indicating to the empty seat beside you. "Are you enjoying the party?" 

"I am, thanks. It's really nice seeing everyone. Seeing Amy grown up, and drinking sure is strange. I remember meeting her when she was about 12. Do you know where Rachel is?"

"She said she wasn't feeling too great, and was going to the ladies just in case". You reply.

The beautiful blonde beside you smirks. "She still can't hold her liquor then?"

"Nope!" You chuckle, although to be honest neither Rachel or yourself have drunken much alcohol at all.

"Rachel said to me earlier that you know that me, and her were 'involved' a while back". Katie states matter of factly after a few moments of silence.

"Yeah, she said that you met via a website, and became inseparable friends". You reply awkwardly.

"We felt different from the other girls, and only had each other, apart from our parents of course. We did everything together, and eventually we became intimate". Katie says, smiling at the fond memories. "We started with kissing, but we agreed not to loose our virginities until Prom Night. She looked so beautiful in her dress the party was the longest few hours of my life. I was desperate to get her home. That night we made love for hours on end. I thought that we were going to be together forever, but after a few months she said she was leaving town for College and that she saw me as a sister or best friend rather than a lover".

"I'm sorry, Katie". You say honestly, at a loss as what else to say.

"Don't be. I treasure the time that we had together, and she's still my best friend. Seeing her happy is all I want, and she's looked so happy this evening". The beautiful blonde smiles earnestly, before her grin turns into something lewd. "Say, John. She told me that you found out what she was packing when she was by the pool".

"That's right".

"What did you think when you saw her rather impressive equipment?" Katie asks naughtily.

"I was shocked, confused, but aroused at the same time". You reply, feeling a little bit uncomfortable at Katie's questioning.

"Was that then that you realised that you liked us dick girls?" Katie purrs seductively, and once again your member swells in your trousers.

"I admit that a woman with extra an had never crossed my mind as being attractive previously, but I soon realised that I still loved her. Her extra doesn't make her any less of a woman to me". 

"Good answer, John". Katie says, smiling happily. "I take it she finally told you about my job". She continues, with a mischevious grin, which you reply with a quick nod. "I'd love to give Rachel, and yourself a show sometime. Either via webcam or in person".

"What was that in the car park then?" You point out, with a mischevious grin of your own.

"That was just the preview!" Katie replies with another lewd wink."I'm getting another drink. It's been great talking with you...stud". She purrs, before rising out of the seat, and makes her way to the bar. Your eyes follow her tight behind every step of the way. 

"Ahem!" Rachel coughs loudly in your ear, snapping you back to from your ogling of Katie's bubble butt. Her beautiful face has an amused smile plastered all over it. "Wanna get me home, and finish what we started earlier, stud?"
