Courtney and I have been dating for about a month and we’ve been having sex for two weeks. No sleep overs yet. So far the sex has been great even though we are still discovering each others bodies.

Last night I was going to spend the night in the city at her place, our first sleep over.

We went out for a nice dinner and since it was a beautiful night, we walked back home to her unit. In the elevator we were making out and my cock was starting to come to life. Courtney made a joke telling me to slow down, she suggested we go up to her pool/spa that is on the roof of the building. Sounded good to me. And yes, I did want to cool down a little bit as I was super horny.

Inside her unit, Courtney went in to her bedroom to get changed. I had to tell her that all I had was a pair of speedos, was that OK?

She replied back that she was hoping that was all I’d be wearing.

It is summer here in Australia, I wear speedos as underwear all the time. It comes in handy a lot, dropping in to the pool on the way home from work, going for a quick swim at the beach, I’ve even been out mountain biking and had the chance to go for a dip in a natural pool and speedos are convenient. While I wear them, I’m not super confident wearing them in public and I’d never have the courage to wear them at a pool party or something like that. Rooftop spa at 10pm at night with a pretty girl, that sounded like a good idea though.

Courtney comes out of her bedroom wearing a tiny black Wicked Weasel bikini. It is too tiny for a pool party (like my speedos) but it isn’t indecent. It has thong bottoms which seem to be in fashion these days and she looks fantastic!

I had been making up some drinks and was still fully dressed, which she was not impressed with. She ordered me to strip down, which took me all of four seconds to whip my shirt off and drop my shorts. We started making out again and it was incredibly sexy us both wearing next to nothing in her kitchen. When Courtney caught me getting hard again she broke off our embrace and looking down at the bulge at the front of my speedo, told me I can’t be full mast, in case there are people up there.

Courtney gave me a towel to wrap around my waist, she did the same and with drinks in hand we headed up to the pool/spa.

This was the first time I had been up there and it was really nice. I’ve alredy mentioned that it was a beautiful night as well. There was one guy sitting in the spa, otherwise the place was empty.

Courtney and I jumped in the pool and hung out there for ten minutes or so and then she suggested we get in the spa.

The spa was pretty big and we said g’day to the guy who was sitting there. He was our age, early 30’s and was enjoying an adult beverage as well. We started chatting to him, Courtney said she had seen him around the building and he told us that it was his last night there, he was moving up to Cairns. Three of us just chatted for a bit and Sam (that was his name) said he was going to get another drink and asked us if we’d like one? At first we delined but he said he had to drink it before moving out the next morning. We accepted Sam’s offer of a G&T, he jumped out of the pool and Courtney’s eyes just about popped out of her head.

Sam was really hot. Swimmers build and ripped. And he was wearing a black speedo that fit him just perfectly. Like he was an olympic diver.

I’ll admit, my jaw dropped and I couldn’t keep my eyes off his arse as he got out of the spa.

Once Sam was out of ear shot I started ribbing Courtney about checking him out.

It was fun and light hearted jeering and we were now hugging with her legs wrapped around me and my hands on her butt.

Courtney said that she noticed my eyes were enjoying Sam’s butt as well, then she asked me if I needed to tell her anything about my sexuality?

Funny she should mention that, I was trying to think of an appropriate moment to tell her that I am open-minded. By open-minded I don’t think I can claim to be bisexual, I don’t date guys, but I will fuck them and I love two guy threesomes. I particularly love a threesome with another open-minded guy.

The words that came out of my mouth were “Courtney, I don’t mind sharing you if that is what you’d like?”

Her answer to that, was thrusting her tongue in to my mouth.

A great response, that could have gone really bad and she kicked me to the curb then and there but her kiss demonstrated to me her enthusiasm to the idea.

When she was done tongue fucking my mouth, Courtney said that she thought Sam might be gay and that if we had a threesome, she would be sharing me and not the other way around. I said she might be right but Sam was more interested in her than me from what I saw.

Courtney then whispered in my ear... “I’ve always wanted a threesome. Will this make things weird between us?”

I told her I was willing to give it a try if she was.

Courtney was keen and told me that I’d have to be the one to initiate it. I told her our code would be if she keeps rubbing my cock under the water it means she is keen, if she grabs my butt it means she has changed her mind and doesn’t want to do it. Sounded good and when we finish our next round of drinks I’ll ask Sam if he wants to join us.

We had a plan. Which went out the window thirty seconds after Sam got back to the spa.

Sam walked up to the spa area and Courtney and I broke up our cuddling, which had my cock rock hard, again. He dropped his towel on one of the lounges and walked over, in all his speedo glory, with three drinks in hand. He really was a good looking guy.
