The next week passed as the previous one - a mix of school lessons and frequent sexual encounters with Abi at home. I was often distracted during my lessons with thoughts of Abi and of the weekend exploits with Mum and Vikki - but strangely, when I was with Abi, I never seemed to be distracted by thoughts of school lessons!
This week, our sessions weren't restricted totally to the bedroom at bedtime as they had been during the previous week. On the Wednesday, we'd both decided we'd fancied a shower and taken it together. That had been gorgeous! We spent ages rubbing soap over each other's bodies - it was such a lovely feeling. And of course, I could never get enough of the sensation of feeling Abi's little nips swell under my hands - so soaping her tiny boobs as I gradually teased her nips to attention was quite exquisite. And then, the fun we had with the removable shower head was brilliant! I spent ages directing it all over Abi's body, but concentrating on her hardened nips, then of course moving lower down! By directing it straight up between her thighs - which she helpfully spread for me - it played on the whole sensitive area round from her cute little rosebud behind to her still childlike pussy in front. I soon had her shaking with arousal, her little cries of pleasure only serving to turn me on more and more as well.
On the Friday, she'd gone straight into the shower when she got home and I'd bumped into her when she was emerging with just a large towel round her. As she returned to her room, I'd gone with her and was soon helping her dry herself - a very pleasant activity! It wasn't long before we both ended up naked on her bed enjoying ourselves as we had done so often over the past two weeks. But this time it was late afternoon rather than at bedtime so was in the full light of day. That made a nice change - but not only for us! We were well into it and making a fair amount of noise when Mum arrived home. From the moment she closed the front door behind her and stood in our front hall, she knew what was happening - and, it seems, wasted no time in rushing upstairs to get a ringside view.
We were only aware of it when, as I lifted my head up briefly from between Abi's thighs, I caught a brief glimpse of a movement in the direction of Abi's door. I looked across surprised and saw her standing there, just removing the smart jacket that she wore to work. She smiled encouragingly at me and I knew she just wanted us to continue so that she could watch. I grinned back at her and returned to my task, and Abi groaned in response. The knowledge that Mum was watching us - and not only watching, but getting very turned on herself - only served to fuel our passion. We had a particularly good session, not only wanting to give each other pleasure but also wanting to "put on a good show" for Mum.
I caught glimpses of her every now and again as I gradually got more and more fired up and could see that she was really enjoying the show! She had followed up the removal of her jacket by unbuttoning her blouse and pushing her bra up out of the way so that we could see her bare boobs peeking through. At some stage, she also removed her shoes, tights and panties so that she had easy access beneath her smart tailored skirt. But most exciting of all was her face - flushed with excitement, her eyes alight with enthusiasm, as her fingers teased and probed.
Abi and I had great climaxes and eventually collapsed in each other's arms on the bed, panting heavily, sweating profusely, and very happy. It was only moments later that we heard a sort of strangled groan from Mum and she sank on to a little chair out of view, shaking with pleasure herself.
On the Saturday, Abi and I decided to go and do a bit of clothes shopping. One of the first things I needed was a new bra. Mum had bought me a trainer bra probably six months ago now, and my first real bra two or three months back - but it was quite small and had recently started feeling fairly tight. Of course, I didn't really need to wear a bra for support, but I did need to wear one to school and some other times when I was far too shy to go bra-less. Abi thought it was quite exciting accompanying me on such a grown-up shopping trip - but we were both quite shy when it actually came to it.
We chose quite a large shop to look in first and tentatively threaded our way through to the bra section. There were bras everywhere, hundreds and hundreds of them! We made our way over to some hangers with some rather nice looking lacy ones and picked our way through them. There were some really pretty colours and they had a lovely soft gossamer feel to them. I chatted enthusiastically about them to Abi, wondering whether I could be sure what size I wanted.
"Can I help you, Miss?" a voice suddenly said softly behind me. "Would you like to try one on?"
I suddenly felt overwhelmed with embarrassment and I could feel my cheeks redden as I looked round to see the salesgirl standing there. She was probably in her early twenties, blond, pale blue eyes, good-looking, and very self-assured - but with a quite warm and relaxed smile on her face. "Err, no, we were just looking really", I stammered.
She smiled again, "Well, that's fine - but if you'd like to try anything on, you're very welcome to". She looked at the bra I happened to be holding at the time. "That one's very pretty isn't it - I'm sure it would look good on you".
I hesitated, in one way desperately wanting to try it on but still very shy of this girl talking about such things to me.
She took my hesitation as agreement I think. "OK, follow me and I'll show you to the changing rooms. My name's Susie by the way. Please ask me anything you want."
She chatted away to us as she wound her way through the racks of clothes to a line of changing cubicles. "Lets go down the end", she continued, "I'm guessing you'd prefer one with a bit more privacy".
I muttered something appreciatively as we followed her, the thought flitting through my mind that the skirt she was wearing was really tight across a rather nice firm pair of buttocks and showing quite a lot of slim thigh beneath.
"Here we are then, I think this one would be good for you", and she led the way into a fully enclosed room, quite unlike the curtained cubicles we'd passed before. There were two large mirrors on opposite walls, two chairs, and hooks to hang clothes on.
"Thanks very much, Susie", I managed to say, quite gratefully, and paused waiting for her to leave us to it, while Abi settled herself down in one of the seats.
But she showed no sign of leaving. In fact, she stood there waiting expectantly. "Err, I think we'll be OK by ourselves thanks", I muttered, embarrassed again when I realised she was expecting me to start with her watching.
"Well I'll leave you to it if you prefer", Susie replied, her voice oozing concern and friendliness, "but it would probably be best if I stayed - then, if it's not quite what you wanted, I can get you some more to try on. Please don't be shy, we're all girls together after all."
As I stood there, continuing to look unsure, she continued soothingly, "OK, I'll step outside while you put it on, then I'll pop back and check what you think". And with that, she slipped quietly out leaving the two of us by ourselves.
I breathed a big sigh of relief. "Oh my God, Abi, she's really nice, but I'd be so embarrassed stripping off in front of her!"
"Yeah, I know", she said, "Come on then, you'd better get a move on or she'll be back inside before you've got it on properly! Let me help - I love taking your bra off!! Not that I get the chance much of course - most of the time you haven't got one on!"
And so Abi jumped up and went round behind me as I peeled my T-shirt over my head. Quickly, her nimble fingers were on my bra catch and she soon had it undone. "There we are", she said, "let's just slip that off" and she slipped the strap from my shoulders and off, quickly sliding her cool hands back up and running them over my bare boobs.
"Abi!" I hissed under my breath, "Stop that! Susie'll come back in and catch us!"
She giggled, a cheeky sexy girlish giggle, as only Abi could. "Here, pass me the new bra and I'll put it on for you then", she chuckled.
So I handed it to her and helped her slide it on for me. She ran her hands round, positioning my cups, then doing up the clip at the back. Then she reached round me again and started to make sure my boobs were properly positioned in the cups. She even slid her fingers inside the bra to smooth it out. Her soft fingers dancing over me like that had an immediate effect on my boobs and they quickly started to respond with the nipples stiffening rapidly.
"Hey, Abi!"" I chuckled, "Careful, you'll get me going like that!"
"Oh really?" she laughed, in mock surprise, and continued to slide her fingers around much longer than necessary.
"Abi! Stop that!" I whispered, "We can't do that here". But my body wasn't obeying my words and my nipples were swelling up even more, as always, loving the attention they were getting.
At that moment, the door quietly opened and Susie stepped in.
"Hi girls!" she started, "How's it going?"
Abi quickly slid out her hands guiltily and stepped away from me as I turned to Susie, flushed this time both from my rising excitement and from embarrassment, and said the first thing that came into my mind.
"Err, fine. What do you think?"
This was her cue to get involved - and she took it.
She stood in front of me and looked, then stepped forward and eased the bra slightly this way and that, checking its fit. I was acutely aware that after Abi's ministrations, my nips were quite sensitive and very obvious, pushing out firmly against the thin material. Somehow, obviously accidentally, Susie managed to brush her fingers across them two or three times as she was doing her adjustments which didn't help my excitement to subside. Especially as I found my gaze drifting down towards her ample cleavage as she stood in front of me. She was wearing a crisp tightly fitting blouse with an open neck and I could clearly see her quite full breasts sitting in a beautiful low cut bra.
She stood back slightly, smiled broadly and said, "That looks beautiful. You've got lovely little breasts you know. But I'm not sure that bra is quite right for you. Your breasts are marvellously firm so you don't need as much support as that one is giving you. Something a little softer might be better - and probably wouldn't squash those lively nipples of yours quite so much! Can I get a couple of other possibilities for you to try?"
She said this so matter-of-factly that I didn't really take in quite what she'd said at the time - so I just smiled, warming to her compliments.
"OK then, that would be nice", I replied, "as long as they're not too expensive".
"No, don't worry - I'll only look at ones for the same sort of price", and she quickly went out closing the door behind her.
As soon as the door closed, Abi burst into a fit of giggles. "Lively nipples! I'll say you've got lively nipples!" she laughed. "I thought she hadn't noticed for a while, but she certainly had! You know, I think she fancies you!"
"Don't be silly, Abi", I laughed. "She must be ten years older than me! Pity though, I think I quite fancy her! She's got a beautiful pair of boobs herself hasn't she? Did you notice?"
"Yes, I did - and I noticed you peeking down her cleavage as well", she laughed. "Anyway, if you ask me, she spent a lot longer fiddling with that bra than she needed too - and checking out your nips too I reckon! And then saying how nice they were! Oh yes, she fancies you all right! And look, they're still standing out now - all this sexy talk I guess. Here, let me just check", and she reached up and quickly ran her fingers over my tingling nips. "Yep, hard as bullets still", she giggled. "Still, I like the idea of a bra that doesn't squash them so much, don't you? I'm sure it's just a sales gimmick, but it sounds good!"
"Abi, will you stop that!", I said to her, pretending to be severe. "Not only are you getting me very turned on, you look like you're doing the same for yourself!" I continued as I looked at the little bumps which had suddenly become quite noticeable on her young chest!
"Don't be such a spoilsport, Liz. You know you like it anyway - so what harm's it doing?" and she continued brushing her fingers back and forth, sending increasing tingles through me.
"Well, Susie'll come in and catch you at it for a start", I laughed.
"Mmm, that might be fun!" Abi giggled in return.
Before I had a chance to reply, the door opened and Susie returned, clutching a handful of frilly bras. Her eyes immediately alighted on Abi's hands on my boobs, a second before Abi quickly removed them, still giggling slightly.
"Are you just checking it out then young lady?" Susie asked Abi, smiling broadly. Then looking down at Abi a bit more closely, she added, "I suppose you'll be needing one of these very soon won't you! And it looks like you've already got the same lively nipples as your sister!!"
Abi giggled a bit more. "Yes, I think they run in the family", she laughed.
Susie thought this idea was hilarious and laughingly said, "Mmm, lucky family!". Now, come on miss, let's try on one or two of these. Which would you like to start with?"
I turned to her, still very self-conscious, and selected one of the bras she was holding out to me. It was in a very soft mid-blue material with a really smooth finish.
"OK, turn round and let's try it on", Susie went on.
I hesitated again, not really wanting her in there when I stripped off the other bra, but this time she brushed my protestations aside saying, "Come on, it'll be fine. I can't keep popping in and out of here like a jack-in-a-box!"
I laughed nervously, and agreed, "OK then. Thanks", and turned away from her so she could undo the first bra.
"That's better", she soothed, "what are your names by the way?"
We told her and she went on, "Right Liz, let's just slip this off then", and slickly unfastened it and slipped the straps over my shoulders. I was very aware of the brush of her tightly stretched blouse on my bare back as she leaned in close to me to help. She reached round the front and gently removed the cups from my boobs, brushing the throbbing nipples yet again! Then she picked up the new one and reached round to slip that on.
It was lovely, a really soft unstructured design. Her hands were warm and soft on me as she eased the cups round my now quite sensitive breasts, her fingers working expertly round ensuring that they were in snugly, then checking my nips weren't too squashed. I could feel her own ample bosom pressing more firmly into my back as she worked and before I could stop myself, I let out a little moan of pleasure as she brushed against my nipples yet again.
"I'm not hurting am I, Liz?" she asked quietly.
"No, not at all", I replied, "that feels lovely".
"Here, let's have a look at you then", she went on, "Turn round and face me".
So I did, feeling now much less embarrassed and instead just very turned on by the whole situation. Not only were my nips still fiercely upright and now even more visible as this bra didn't squash them quite as much, but I realised I was breathing more heavily and feeling distinctly warm.
Susie stood back slightly and looked at me. She smiled broadly. "Liz, that's beautiful! They really are lovely. Don't you think so Abi?"
Abi chuckled, saying, "It's gorgeous, but then I think she looks pretty good in anything!"
Susie laughed. "Yes, maybe you're right, but I still think that enhances her natural good looks. Here, let me just check how that's fitting from the front", and she stepped forward, her cleavage seemingly even bigger and more enticing, and her fingers danced over the cups yet again. I don't know what she thought she was doing, but I just knew it was feeling wonderful and I couldn't help letting slip another small sigh of pleasure.
Susie looked up at my face and her eyes met mine. And then I knew that she was enjoying this as well! I could see it in her eyes, and the small smile playing across her lips. And I smiled back, now just not wanting her to stop.
"I think that's just perfect now", she continued, and I noticed her breathing was now definitely a little faster, "and it's soft enough to allow your beautiful nipples a little space. I must say, for one so young, they really are gorgeous!"
She dreamily ran her fingers over each in turn and I couldn't suppress a little whimper of pleasure. "And I see they're very sensitive too. You really are very lucky".
Then, thoughtfully she suddenly turned to Abi, who was sitting watching with growing excitement herself. "And yours are developing the same way are they, Abi?" she asked, her eyes darting down to Abi's barely perceptible boobs, but quite obvious bumps from her hardened nipples.
"Seems like it", Abi giggled sexily, "they certainly get very sensitive too", and she almost absent-mindedly reached up and rubbed them briefly.
"Well...", Susie went on, her face looking unmistakably a little flushed now, "how about some matching panties for that bra, Liz? And maybe, whilst I'm out there, I could pick up a couple of oddments for Abi too. Would that be OK?"
We both nodded appreciatively, not because I really wanted to buy any panties, but just because I was beginning to enjoy the whole experience and was happy to do anything to prolong it!
"OK, I won't be a moment", and she was gone.
The second the door closed, Abi was out of her chair and cuddling up behind me. Like me, she was feeling turned on and I know wanted to press herself up against me and to feel my new bra as well. "Wow!" she exclaimed from behind me, "This is getting interesting isn't it. I knew you were getting turned on from the start, but now it's obvious Susie is as well! I told you she fancied you didn't I. Do you believe me now?!"
I laughed, "Yeah, I believe you. She really seemed to be enjoying herself playing with my nipples! And anyway, I could tell from her face. Did you see it? She was definitely getting more involved there... I wonder if she's gone to cool off, or to return to have a bit more fun?"
"I don't know", said Abi, then, looking past me into the mirror she added, "Hey, look, I can see my hands on your boobs in the mirror!" and she giggled even more as she enjoyed herself and started working me up even more as I watched in the mirror as well. I could feel her grinding her little boobs against my back, the hard little nubs of her nips rubbing back and forth. I really was getting into this, and could feel the familiar tingles starting in my pussy as well as the slowly building pleasure from my nips.
I groaned again as Abi continued, "Oh God Abi, I hope she either wants to have some fun, or she doesn't come back at all. I really am getting quite hot!"
"Mmm, me too", she murmured, "I'm quite getting into this!", and I felt her lips nuzzling the nape of my neck as she held me even tighter.
Suddenly, the door quietly opened and Susie was there again. She came in so quietly that we didn't notice until she was there. As soon as she realised, Abi immediately broke away again.
"Just checking how that one feels, Abi?" Susie chuckled. "It's OK, you don't have to stop just because I'm here you know!"
"I guess not", Abi giggled nervously, but nevertheless sat back down again to watch.
Susie was holding various pairs of panties and flimsy little bras, which she placed on the other chair beside her. "There we are then", she continued, enthusiastically. "Let's see what these look like on you... Mmm... what have you been doing to this bra, Abi?!" she said in mock annoyance, "I'll just need to straighten that again first I think", and so saying, her fingers danced across my boobs once more, doing absolutely nothing to the bra that I could see, but brushing my very sensitive and responsive nips repeatedly yet again! As she stood briefly in front of me, I gazed hotly into the open neck of her shirt, which now seemed to be revealing even more than before. I felt sure that there was an extra button undone as I could now see a lot of her very beautiful fine silky bra, only half concealing the lovely swell of her breasts. I strained to see if the nipples were visible through the tight constraints of the shirt, and could just make out the subdued bumps. How I longed to set them free!
"There we are then - I think that's better. Now... shall we try these panties? What do you think about these - aren't they just exquisite?" and she held up a pair of matching blue brief panties.
I had to agree that they were lovely and nodded enthusiastically.
"OK, then, let's get these jeans off shall we - then we can see how they look. If you can just undo them for me - then you can sit down and I'll ease them off".
Well, the whole atmosphere had changed now and, amazingly, I barely hesitated in murmuring agreement and reaching to unclip the jeans. I eased them down over my hips and suddenly I was standing there in just a bra and panties, with my jeans round my knees!
"That's it", Susie said, slightly hoarsely. I glanced at her face and there were beads of perspiration on her lip. "Now, just sit down there while I pull them off".
The panties I was wearing were black which was probably just as well - I'm sure they were distinctly damp by now, but it wasn't that obvious on the black material. Susie knelt in front of me, removed my trainers, and then expertly slipped my jeans down and off over my feet. My almost bare backside on the cool chair felt exciting and from where I sat now, I had an even better view down Susie's shirt! I suddenly got a hint of the smell of my own arousal now that she'd removed the jeans and I couldn't help wondering if she noticed it too.
Laying the jeans carefully to one side, she looked back up at me, "Wow, you have a cute little body", she said, "These panties are going to look brilliant on you. Come on then, let's slip these off so we can try them on".
I reached down and eased my panties down over my hips, gradually peeling them down. Susie's eyes were glued to them, and as I slid them down my thighs, exposing my rather hot and damp pussy to the fresh air, I noticed her instinctively lick her lips! She leant forward and slid them off down my legs for me, her eyes never straying from my pussy!
"Mmm... I see you have a lively pussy as well as nipples", she chuckled,
