Julia had just informed Barbara that she was to be fucked by three different men that evening. I hadn't been at all surprised at my girlfriend's immediate, unquestioning agreement. But it seemed Julia was.
"Jesus, Babs! You are for real, aren't you? Oh. I feel bad now. I was expecting to see you run a mile at the thought! Are you telling me you'd really be OK if I arranged for three strangers to come here and fuck you?"
"Well yes," Barbara shrugged.
"And you Dan? I mean, I know Babs has been experimenting a bit recently, but you'd have no objection to some well-hung young studs banging the shit out of your lovely girlfriend there?"
I glanced at Babs. All I could think about at that moment was her following in her friend's footsteps. We'd spent the afternoon so far enjoying the sight of the stunning Julia, under her porn alter-ego of Julia Sterling, having sex with any number of men.
"Honestly, no! Wait, are you saying that your masseur, those other guys, they aren't really coming over to see to her?"
"Well, no! I am a bit flabbergasted, I clearly misread the situation, underestimated just how much you've managed to corrupt Barbara! Well, this changes things a lot. I might be able to arrange something along those lines, before you go home. You are one hundred percent, you wouldn't back out?"
"No! Julia, I was getting so horny at the thought! You little tease, promising me all that and then taking it away again!"
"Oh, my sexy little Babs! I'm so sorry for leading you on!"
If I'd thought the atmosphere around Julia's home had been sexually loaded before, that proved to be nothing. It was like Julia had the handbrake on up to now, but the realisation of exactly how much her friend had descended into debauchery seemed to almost flick a switch in her.
She decided to make up to Babs personally, the broken promise. And the first stage was delivered personally. Babs had already confessed that she was interested in girls as well as guys, and Julia had a mind to give her experience in this field. I watched in awe as she knelt on the couch beside my girlfriend and began kissing her neck and nibbling her ear.
Barbara's face was a picture, catching my eye and giggling a little at my expression, before turning and kissing her friend passionately with very little hesitation. My phone was now in my hand as I began to get some pictures. I reasoned that Julia would have no objection, as widely published as she was, and I was right. When she spotted the camera, she posed and smiled sweetly right into the lens.
Making a big show for me, she made her way down my girlfriend's body, taking time to squeeze and caress those perky tits I loved so much, all the while making sure my camera had the best view of proceedings. Soon her face was between Barbara's legs, which parted obligingly.
Babs enjoyed Julia's attentions very obviously and eagerly, her friend's tongue and fingers expertly giving her several loud and shuddering orgasms, all of this being caught on my camera. But this was just the start.
Soon Julia's tongue began attending to my girlfriend's anus, rimming and teasing lovingly for some time. Barbara, unsure at first, slowly began to enjoy this attention, making lovely appreciative noises as her friend's tongue began to stretch her little hole open.
Julia soon produced some toys, and Bab's asshole was stretched by larger and larger glass butt plugs. I was chronicling all of this with picture after picture, and this continued as Julia moved onto her dildos, and my girlfriend started to understand what being fucked anally felt like.
I wouldn't have dared ask for more, but when Barbara asked me why my cock was still in my pants and not inside her friend, and Julia turned, face covered in pussy juice, with a smile that told me that her body was mine to replicate anything we'd watched her do in her films, I felt like my life had peaked.
The feeling I got as I eased inside Julia's famous cunt, still tight and elastic despite being so frequently used over the years, was indescribable. The sight of Barbara smiling and urging me on as her friend brought her to orgasm after orgasm was not, I knew, something I could ever have hoped for and would never take for granted.
And when Julia ordered me to cum inside her, before she then kneeled over Barbaras face and invited her to clean up, I could have reasonably claimed to have completed sex. It would never get better than this, surely?
Barbara took to this invitation with the initial tentativeness of a girl tasting another girl for the first time, but growing into the hungry passionate tonguing of a whore who enjoyed the familiar taste of her boyfriend's cum mixed with the new taste of a nice wet cunt.
Over the following three days there was a constant backdrop of Julia's extensive range of pornography, and Julia continuing Barbara's education. I was frequently called upon, and my cock became familiar with the inside of my girlfriend's rectum, as Barbara took to anal sex with great enthusiasm.
She learned how to take multiple penetrations, albeit with only one real cock, but Julia took delight in pushing realistic dildos into her friend, choking her and filling her pussy. I experienced the curious feeling of thrusting into her slippery vagina whilst her anus was filled, just a thin partition separating my cock and the silicone one pushed up inside at the same time.
She took everything, not just gamely but with an eagerness that made me wonder if there was any limit to what she'd do, what she could take. Julia had set the example and Barbara now considered the bar had been set, she was going to do anything and everything her friend had done so often and so well.
Barbara repeatedly encouraged me to make use of her friend, reminding me that we were only here for a few days, and that I'd be mad not to use this opportunity to get my hands on such a beautiful, sexy and willing whore as Julia. And, as she reminded me, she was absolutely going to continue to enjoy exposing herself to strangers, fucking them and sucking their cocks, whenever she got the chance. That was a given, so I should feel free to enjoy other women without guilt, should the opportunity arise.
I only wished I had a fraction of the sexual stamina these girls had because, if I had, I'd have fucked Julia more than the once or twice daily that I managed. Waking up in the morning with our host's lips wrapped around my cock, as happened on each of the four days we'd stayed so far, was amazing.
Barbara stirring and then smiling as she saw what was happening, before slipping down between her friend's legs, or presenting her pussy to me so I could taste her for breakfast, was magnificent.
On our last full day, I knew Julia would have a plan for her friend. Given how disappointed Babs had been when she'd realised Julia was joking about finding some random guys to fuck her, I knew what was likely coming. Barbara had spent most of her waking hours in a state of intense arousal, anticipation for what was coming overwhelming her.
After breakfast the doorbell rang.
"That's probably the postman, can you go for me please Babs?" Barbara was wearing only a t-shirt which barely covered her but was out on the porch signing for the delivery without hesitation. We watched through the window, Barbara taking her time to sign, firstly making to lean on the door before deciding to use her knee as a rest.
This meant she was able to give the middle-aged, bearded postman a direct view of her pussy, which he enjoyed very much, judging by his thanks when she handed the card back to him.
"She really loves it, doesn't she? Showing off like that? A true exhibitionist." Julia again spoke like a proud mother; she was enjoying Barbara's continued enthusiasm for anything sexual as much as any of us.
We were still none the wiser about Julia's plan for this evening, which was our last before returning home. Julia had disappeared for most of the afternoon, leaving us to entertain ourselves.
In her absence we both unconsciously went into reflective mode. It was like Julia was the kindling to both of us, with regards to our sex drive -- at least for the duration of this little break. So, her being away was a time to take stock, to wait for her to come back and raise the temperature again.
"Are you having fun, Dan? I feel like this break, our time here, it's been all about me. You aren't feeling left out, are you?"
"Are you kidding? Even if I'd spent three days just watching you and taking pictures, that would have been a dream holiday. Both of you, doing the most amazing things to each other, that would have been something else. But I've been fucking Julia every day too! I never could have dreamed you'd be OK with that. It's been the best few days of my life."
"Oh Dan, that's such a relief. I know you keep telling me, but I struggle to believe you're OK with all the stuff I've been doing, all those different men. It helps me a lot to know you are having some fun too. I bet she's an amazing fuck, is she?"
Barbara's face was so genuine, so loving. She honestly wanted me to enjoy her friend.
"She is -- I mean, not as good as you, obviously," I winked.
"Obviously," Barbara replied with a hint of sarcasm. "I mean, how could the world-renowned porn star possibly begin to compare with the teacher who was a virgin until last year, eh? I just hope I can be half as good as her, one day."
"Babs, it's not just about experience. Trust me, if we lined you and Julia up and asked the world to vote on which one was the most fuckable, it wouldn't be a foregone conclusion."
"Shut up!" Barbara laughed. "But thanks, all the same. I just know how I feel about her. Looking back, I had dirty thoughts about her even back at Uni, I just wouldn't admit it. When she was out meeting up with guys, I was jealous -- both of her for having all this fun, but also of them, for getting their hands on her. Honestly, I'm jealous of you -- if I had a cock, I'd fuck her too!"
Despite everything, the novelty hadn't worn off. The memory of prim-and-proper, workaholic headmistress Barbara wasn't too distant to make the current filthy-minded little slut, desperate to try to emulate her porn-star friend, the most arousing thing I could imagine.
