My girl friends and I returned back from a short Spanish holiday, this time last year. It's in a place where hedonism is kind of expected and sort after. And before we went, we nearly all agreed we'd have sex with as many guys as possible, keeping score. All except my older sister Amy, who was with her boyfriend of two years.

Within the first few hours I had a Spanish guy checking me out near the pool. We'd not long unpacked and my room mate Lucy was telling me he couldn't stop looking at me as I lay next to my sister. Thinking of our challenge, I walked over to him and told him to meet me in our room in ten minutes. After sucking on his above average sized cock for less than five minutes, he came all over my face and that was it.

Over the next couple of days, each of the girls, except Amy, went with lads around our age or a little older and had casual sex. My angle was to pick out older men after the debacle of the lad at our hotel pool. And I must say I had some really hard sex one night with an older Brazilian man in his forties.

The last night there, Amy was ill and stayed in. We all persuaded Ryan her boyfriend to come out with us and he said he would, but only for an hour or so. My friends began their man hunt, drinking in bar after bar, but I really felt bad on Ryan, so I asked him if he'd like to remain in the first bar with me. We chatted as we drank and out of nowhere he asked me if I'd enjoyed having sex with any of the men I'd been with. I told him I'd bragged a lot, but I'd actually only had full sex with one person, explaining the failure to have intercourse with the Spanish guy. Ryan put his hand to my face stroked along my neck line and told me he'd never allow himself to be so selfish with a beautiful girl like me, and if he took me to bed, he'd have me orgasming all night.

Telling him it was the drink speaking, my sisters boyfriend then told me he'd fancied me for a long time, but never had the chance at home to say anything. Moving closer whlst still holding my face, we kissed.

We saw the girls in a bar close to the beach as the clubs began to open. Ryan and I were headed to the beach and for only one reason. Outside of the bar we'd been in, we moved around the side of it, kissed some more and then I dropped down to meet the biggest cock I'd ever seen poking out of his shorts. Amy had made mention of Ryan's attribute in the past, but I just put it down to her trying to make me feel jealous. She hadn't been exaggerating. Unlike the Spanish lad, Ryan fed me his cock with confidence and I'd licked, sucked and even bit slightly along it. Sucking in his huge mushroom shaped cock head, I heard him telling me I was much better than Amy.

Having reached the beach and moved on up past the breakers into the dunes, I was so full of sexual need and feeling so horny for his cock. Sucking it back into my mouth as he'd taken off everything except his flip flops, I greedily sucked on his fully erect cock. His breathing changed and I knew like many before him, he about to cum. So I stopped held his balls and rose up. lifting my short flowing dress up and over my body, leaving it next to us on the sand, I offered up what I knew to be my bare sex.

The Brazilian guy had been good, really good. Yet my sisters boyfriend when he slid his bare cock into me from behind, was simply on a different sexual level. Right from the first thrust up my dripping pussy, Ryan sank it so deep inside of me, making me gasp with desire and sexual feeling. Everything became focussed on what we were doing and I orgasmed within a couple of minutes. After shuddering through my first, we moved onto the sand itself and over the next hour, we fucked in all kinds of amazing positions. The crunch for me, the absolute sexual mind blower was going to impale myself on his cock and feeling it slide past my pussy into my arsehole. It was a mistake, but one I was never going to let him know. Gritting my teeth, I felt Ryan arch upwards forcing his cock deep inside my bowels. His face changed to, to one of sheer wonder and delight. He knew he was in my arsehole and to him, and me I guess, it was a first.

Close to three in the morning I kissed him goodnight at his and my sisters room door. I'd orgasmed so many times with him fucking my arsehole, I was literally drained. He'd cum twice and the second time I'd let him toss his cock over my face. Opening my mouth I'd watched as it flew over my tongue and I gratefully swallowed every drop.
Sat on the transfer coach waiting for Amy and Ryan, being the last of our group, I thought they might have argued. I
was wrong, as they appeared together holding hands. It made me feel relieved and wanting them to be ok with each other. With Ryan sitting directly in front of me, Amy sat next to me. My sister smiled at me, held my hand and said "Ryan said you loved it up your bum, that's not for me. Maybe you two should be an item".

I sat in total shock all the way to the airport and on the entire journey home.

Back at home, my sister explained they'd decided before we went, if Ryan and I had gotten close, she wasn't going to stand in our way. What I didn't know, is they'd been sort of split for a while, using the short break to see if they might want to carry on. Only he'd expressed to her how he felt about me. I also didn't know, the Spanish lad who I'd sucked off in my hotel room, was from the very start actually interested in my sister. I'd jumped the gun thinking it was me who he was interested in. Lucy had gotten it wrong and helped that I suppose.

The real reason she'd not joined us that night, was she was having sex with the Spanish guy in his home. Something Ryan already knew about. As Ryan and I had been kissing outside their room, she was till bouncing up and down on the Spanish guys cock.

Myself and Ryan are still together and loving our very sexual relationship. My sister is now living in part, half of her year here in the UK, and part of her year in Spain. It was a funny way for us to find out what we all wanted, but I now wouldn't change how everything worked out.
