I was excited as my new suit was due to arrive today and the only question mark was who was going to deliver it and check the fitting, in one way I was hoping it was Gail but on the other hand it would be nice to meet her younger sister Gabby but time would tell as I waited for the confirmation phone call.
I didn't have to wait long before the call came and it was Gail who explained that due to her workload she was sending her sister around with my suit and accessory pack and from the tone of her voice I got the impression that Gabby knew something of what went on at the measuring appointment. Gail explained that Gabby would check that everything fitted correctly and would make sure I was completely satisfied, whatever that meant.

I stood by the window in just a pair of short sports shorts and saw a taxi pull up and stood open mouthed as Gabby got out the cab, OMG she was about 5'2 with short blonde hair and from what I could see was damn cute, she had a short crop top and even shorter denim skirt which complimented her slim, tanned figure.
As she walked towards the house carrying my suit in one hand and accessory pack in the other she must have seen me in the window as a beaming smile came across her face and if I thought Gail was hot then her sister was drop dead gorgeous. 

As she got closer it became obvious her skirt was a wrap around skirt making me think she knew how to dress for the occasion and as she came up the path I rushed to the door to greet her, "Hello Frank" she said cheerfully and as she ran her eyes over my semi naked body she added, "Oh you must have been expecting me" which made us both laugh.
She entered the hallway and I asked her if she would remove her shoes which after passing me the clothes she happily agreed and I could see she had dainty little feet with light blue toenail polish, unbelievably cute. 

Two things came to my mind while I stood there holding my order, one was her while crop top which wasn't particularly tight and was obvious she wasn't wearing a bra and the second thing was her short denim skirt was a wrap round and held by what looked like a single button and looking at her I just hoped old Percy would behave himself. "Can I use your bathroom first please Frank" Gabby asked and I told her it was top of stairs and turn right and I wasn't going to miss her going up the stairs. Oh yes, a perfect view up the back of her skirt showed a pair of white cotton panties which were half wedged up the crack of her arse and one thing was certain, she had a lovely shapely arse on her.
I went into the lounge to wait for her return hanging the hanger on the back of the door and putting the accessory bag on the sofa and sat down to wait for Gabby to refresh herself.
Gabby returned and sat down on the sofa getting the delivery ticket out of her bag, "I will need to ensure everything fits you perfectly Frank, is that ok?" she said softly and albeit she was young she seemed to know what she was doing, "Yes that's fine Gabby, where do you want to start?" I asked standing up in front of her, Gabby looked up at me, "Hmm, nice Frank, as you are only in your shorts I suggest we start with the boxer shorts" she said pulling a pack of boxers out of the bag, "Would you like me to leave while you try them on?" she asked and I could tell by her face she was hoping I would say no but I didn't and gently pulled my shorts off. 

Gabby's face was a picture as she saw me standing there naked with my cock hanging down and seemed to fumble in getting the package open, eventually she got a pair of plain boxer shorts out and handed them to me trying not to make it obvious that she was looking at my dick. I pulled them on and then stood back so she could look at them and I noticed that her nipples were poking through the thin fabric of her top, "Oooh Frank, they look nice on you" she said softly and I felt like a model standing there.
As she leant forward I noticed her knees part slightly and with it being a wrap round skirt she was showing a bit of tanned thigh and it appeared that she didn't mind.
"Step forward please Frank, I need to check the fit" she said softly and I followed her command and moved closer to allow her to do her job, she seemed a bit tentative at first but then reached out cupping my balls which certainly had the desired effect as my cock twitched, she had a nice touch.
"Hmm, they seem to fit quite well Frank, how do they feel?" she asked and to be honest with my balls in her hand I have to say it felt rather nice. She could see that my cock was beginning to stiffen and still holding my balls with one hand reached forward with the other and undid the button on the fly, "And you have easy access here too Frank" she said as she put her fingers inside pulling out my semi hard cock and holding on to it. 

"Oh I'm so sorry Frank" she said with a giggle as she pulled both hands away. "I was getting a bit carried away then" she said apologetically and I had to reassure her, "Its OK Gabby, you need to make sure everything fits perfectly" and the fact she had hold of it made the erection process easier as her eyes widened seeing my cock stiffen. "I guess this is a good opportunity to ensure they are comfortable with an erection Frank" she said softly reaching out and grabbing my stiffening cock and trying to push it back through the hole. 

I now stood there with a visible erection now hidden beneath the quality fabric of my new boxers and as I stepped back Gabby seemed to be showing a lot more thigh as her skirt fell open and her white cotton panties were now on display forcing me to make a comment, "Oh I do like your skirt Gabby" I said softly which did seem to make her blush but she made no attempt to cover herself up, "Oh thank you Frank, you're so sweet" she said softly as she took out a packet of thongs that were in the bag.

"These are complimentary Frank, Gail said you like thongs" she said with a giggle and as she unwrapped the packet and took one out I could see that it was quite flimsy and VERY transparent, I stepped closer to her, "Would you like to do the honours?" I asked with a grin and as I stepped closer she widened her legs to accommodate me and now looking down I had a clear view of her pantie clad crotch and could just make out a few stray dark pubic hairs poking out the sides, obviously the carpet doesn't match the d****s.
Gabby put the thong between her teeth as she reached out and started to remove my boxers pulling the front outwards and over my boner which was now standing loud and proud and once they were at my feet I stepped out of them. 

Gabby had to lean forward as I lifted each leg and it was no accident as my cock pushed against her face as she tried to get my feet inside the flimsy thong, I could feel her lips pressing against my rigid shaft which led me to ask her a question, "On the subject of fitting Gabby, do you think this would fit into your mouth?" I asked with a giggle trying to make a joke out of the question and didn't think for a minute she would take it seriously, she let go of the thong she was trying to get on me and looked up, "Mmm interesting question Frank" she said softly and then looked down at my totally erect cock, "Maybe we should try it and see" she said as she reached out and wrapped her little fingers around the shaft pulling the skin right back exposing the swollen head which started to ooze a little precum. 

Without another word she leaned into me wrapping her lips around the head and I gasped as I felt her warm lips enveloping the head and her tongue flicking around the head and then very slowly I saw my cock start to disappear into her mouth. I wondered how far it would go before she gagged and I was starting to feel the tightness of her throat when she gagged and pulled back but then she went right back at it and slowly bobbed her head taking a bit more with each movement and as I felt the tightness of her throat again she carried on and fuck me it wasn't long before she had deepthroated me and I felt her tongue flicking my balls.

Gabby was good, in fact she was incredibly good and had total control of my tool and after a couple of minutes she pulled back leaving a trail of saliva hanging between my cock and her mouth, she looked up at me with her sparkling green eyes wide and dreamy, "How was that Frank?" she asked while her hand was slowly wanking me, I was speechless and stood there open mouthed while Gabby looked totally proud of herself and judging by the state of her crop top with her bullet nipples pushing at the thin fabric she was horny as hell.
"Wow Gabs, that was awesome but can you do it again?" I said jokingly and without a word she leant forward while still looking up at me and very slowly took the whole length back into her mouth, I was amazed at her total control.
She had that teasing look in her eyes and if I am honest it was turning me on more to know that she was definitely up for some fun but what was interesting was her expertise that told me she was no stranger to oral sex; I thought her sister was good but her younger sister Gabby was far better and having total control over me.
She pulled back again and ran her tongue down the length of my throbbing rod and started to lick and suck on my balls with on hand gently rubbing my saliva-soaked cock, it would appear that trying on clothes was the last thing on her mind right now as she now had one of my balls in her mouth and I certainly wasn't going to stop her.
I put one hand on her head and gently ran my fingers through her fine blonde hair which she seemed to like as she continued to worship my meat and two veg but what she didn't know was just how close I was to cumming. 

Gabby pulled back and with one hand cupping my balls and gently squeezing and the other jerking my throbbing wet rod I was almost ready to fire my seed in her direction, my knees started to shake and I wondered if she wanted a facial or weather she would force my cock back into her mouth for the money shot, only time would tell on that as she started to quicken her strokes and opened her mouth in preparation, "Oh yes Frank, that's it baby, give it to me" she sighed as the pressure on my nuts increased and I knew I was there.
Gabby's concentration was immense and it was like she felt my man seed shooting up the shaft as just as I was about to fire the first load she positioned her mouth in just the right place taking the first spurt full on, "Mmm, that's it Frank" she muttered as she swallowed the first load and then quickly placed her mouth around my spurting shaft. 

She was loving it as she squeezed my balls and sucked the last few drops from me and I could see her cheeks concave as she went about cleaning me up, I was amazed at her technique which left me weak at the knees. When she finished she pulled back with my softening cock still in her hand and looked up licking her lips, "OMG Frank, Gail said you had tasty cum and now I know she was right" she said softly which confirmed that the sisters had talked. I wasn't shocked at her disclosure as I knew that sisters talk and when I looked down at Gabby I could see her nipples were like coat hangers pushing against the fabric of her thin top and with her legs still wide I could also see the gusset of her panties seemed to have got tighter, Gabby was hot as hell and feeling horny. 

I decided it was time to return the favour and stepped back a stride looking at Gabby's unmistakable beauty and I could see the look in her eyes told me that we weren't finished yet and with her legs still spread I knelt down in front of her and reached forward and undid the button on her wrap around skirt which opened it right up so I was able to remove it completely. Gabby then stood up and I had her white panties invitingly in front of my face and I wasn't going to ignore the opportunity as I ran my hands up the back of her tanned legs forcing them inside her panties while pulling her close to me, my face was now buried in the moist white cotton, Gabby moaned softly as her hands rested on my head. 

Oh the warmth and lovely aroma being omitted from her knickers was sending a rush through my head and while my fingers searched out her crack my tongue got busy flicking the stiff nubbin under her damp gusset, "Mmm that's so nice Frank, I heard you liked panties" she said softly as her legs widened allowing me better access between them. I was like the cat that got the cream as I nuzzled in her private place and I could tell from her breathing how much she was enjoying it.
I turned her around and OMG she had the most perfect rounded arse and I decided that now was the time that she lost her knickers, I grabbed hold of the elastic waistband and gently pulled them down her smooth tanned legs and her perfectly symmetrical arse cheeks now faced me and her thigh gap showed her protruding labia lips surrounded by a few black pubic hairs.

I gently ran my hands over her bulbous cheeks spreading them apart with my thumbs and gently pushed her back so she bent over the sofa and with her cheeks parted exposing her dark shaded arsehole I was totally in my element as she prepared herself for what was to come. "You like my arse Frank?" she asked in a rather breathless voice and I wasted no time in bending forward and running my tongue up and down her crack taking in the exquisite taste of her ring. "Oh yes Gabby, very nice indeed" I replied as I got to work poking and prodding her with my tongue and I physically felt her pushing back on my face as her hole opened up. 

With my face totally buried in her rear end I reached my arms forward and up under her loose-fitting top and now with my hands full of her firm 32b's I had her nipples digging into my palms and Gabby was moaning how good it was felling, "OH YESS!" she cried out as my tongue ran down towards her hanging lips and with my cock now rigid and throbbing I was ready for more, "Do you think it with fit in here Gabby?" I asked as I pushed my finger into her wet and waiting arsehole, Gabby sighed as she caught her breath, "Only one way to find out babes" she replied giving me the green light so with my finger still inserted I raised myself up taking hold of my cock in the other hand. 

As I gently withdrew my finger I ran the swollen head up and down her crack feeling Gabby's anticipation building and when I was at my target destination I gently pushed the tip into her causing her to cry out softly however as I felt her pushing back I think she wanted it pushed in so I didn't disappoint her as once I had got it in an inch it slipped further much easier, OMG her arse was tight but it was a great feeling as I got inside her up to the hilt.
"Oh fuck yes Frank, Mmm that is so good" she sighed as I started to pound her from behind something that I didn't do to her sister so Gabs was getting the full benefit of a good arse fucking. 

I was building up quite a head of steam and Gabby was playing her part by gyrating her hips as I held onto them and from her grunting I knew she was enjoying what I was giving her, all the time I was pounding away I kept thinking how she had got so much experience at such a young age as I could tell this wasn't the first arse fuck she had experienced and being fresh out of school it became an intriguing thought, did she do this with every fitting appointment? From her oral expertise I had concurred that she had more cock than her sister and as the many thoughts ran through my mind I was getting into a nice rhythm. 

Did she have brothers? Did she have an over active daddy? Was she the school bike? So many thoughts would have made sense and just thinking of each scenario was pushing me closer to filling her rectum with my man seed, I was getting so into it that a constant slapping noise was sounding as I banged against her bouncing arse cheeks and then I felt my balls tightening, "OMG Gabs, I'm Cummmmiiiiinnnngggg!" I cried out and immediately felt my cock starting to pulsate deep inside her, Gabby was breathless.
It was an immense orgasm which kept cumming and cumming and I was totally spent as I felt the last spurt hit home and just rested on Gabby's back while I regained my breath, "Oh WOW! Frank, you certainly know how to fuck an arse babes" she sighed softly and as my cock softened I gently pulled back and watched as her stretched arsehole closed up trapping all the goodness inside.

As Gabby turned around she saw a drip of cum on the tip of my cock and quickly bent down taking my cock in her hand, "Oooh Frank, we don't want to waste any do we?" and quickly sucked the tip cleaning off the last drops and I had to hand it to her, she did like cum.
"We seemed to have got side-tracked from the job in hand Gabby" I said with a smile and she looked up at me returning the smile, "I know right, how crazy is that Frank" she replied and I could see from her expression that she had enjoyed the distraction. 

I finally got to try on my suit and even though that process didn't go by without more touching I have to say I was totally impressed with the whole suit purchase process and before Gabby left I had to find out how she had gained so much experience sexually.
It came as no surprise that Gabby had two older brothers and with Gail at 20 being the oldest it was obvious that their parents had a terribly busy 4-5 years as Gabby was, at sixteen, the youngest.
Gabby thanked me for my custom and my hospitality and as she dressed herself I noticed her panties still on the floor so I picked them up, "Haven't you forgotten something?" I said smiling, she looked at me a winked, "No, it's ok Frank, you can keep them" she said smiling.. What a girl.
