A straight forward couple

Me and my boyfriend were secure in our love. I never saw him looking at other women, I never had a reason to look at the other guys either.

In bed we kept things simple, his dick was average but I didn't mind. Then we found this email from a company for this vacation on the beach in a private house. Looking to change up our sex life we agreed. It was fairly obvious to us both the nature of this vacation, we knew that there would be some strange things.

We had assumed our relationship would be strong enough to endure this and come out with some great experiences... But after getting here and guided to the room.. I started having doubts. Two other couples shared the room with us... The same bed even. All six of us on an extra large bed.

I couldn't exactly fault Jake, my boyfriend, for staring at the girls... They were half naked on the bed giggling. Unlike me their chests were spilling out of their bras making me feel ashamed of my own modest breasts.

But my attention wasn't on them for long. Rather with the gravity of a black hole my gaze was drawn to a man seated on a chair drinking a water. More specifically to the rather sizable bulge in his shorts. He obviously was working out before we had come in and had worked up a sweat his bare muscular chest on display. To make things worse the bathroom door opened and the other guy arrived with a towel too small for him around his waist. I could actually see the heavy meat hanging low below the towel. Even soft it was massive.

The girls on the bed sat up and noticing the indecent man coming out of the shower giggled and one of them threw some boxers at him which solved that problem.

Jake's POV:

I felt secure when we had stepped into the beach house. It was going to be a great summer I could feel it. Further confirmed by the rather hot women I would be sharing a bed with. They were sexy for sure. My gaze locked to their thighs I could see their panties dulled firmly up covering their pussies I found myself gazing at the spot entranced by them. Until they sat up and my gaze was blocked.

One threw some clothes at a man who just came out of the bathroom. He seemed normal? I mean it's not like he had any features that made me insecure. Another guy who did make me feel slightly embarrassed was a muscular man who had obviously been working out.

But then I saw my girlfriend. Sarah was looking at me and I felt the love I had for her blossom. So I smiled reassuringly at her. We had known that this was going to very sexual before we came, so other than some mild surprise I didn't mind so much.

A girl on the bed drew my attention back and I found myself dry swallowing and my cock hardening. She now sat with her legs crossed under her leaving a very visible window to her crotch as I looked down at her. Her panties stretched conforming to her pussy lips.

"Hey! I'm Carol." She said her voice smooth as she pointed to the muscular man. "That mountain of muscle is my man Mike." When I turned back to her there was no mistaking the way her eyes darted down my form and rest on my crotch a moment before she looked back up. I felt weird, I had never been looked at like that by anyone let alone a woman so hot while she was half naked.

Distracted from her though the guy who had come out of the shower spoke up and I realized he was now wearing shorts instead of a towel. "You two are late missed the introduction. Here, these are for you." He held out two phones to us which me and Sarah took.

"I'm Hector" His arm reached out and patted the other woman on the bed that didn't speak to me. "This is Diana."

Diana shrugged blushing and carried on for him. "We were told who you were already so you don't have to introduce yourselves if you don't want to. We do have to get changed for the first task though."

My questions about the tasks though were answered by Mike the muscular man. "Yeah apparently we get tasks to do and get rewards for participating." He held up a phone of his own. "Just check your phone, you'll see."

Sure enough there it was. We were to play a game of spin the bottle in the hot tub. Meaning swimsuits... I looked up and if they could I'm sure my eyeballs would have fallen out. Both the girls were bent over completely naked fishing out swimsuits. All three of us guys were staring at them until I received a pinch from Sarah to remind me not to stare too hard.

But when I turned to reassure her she was storming into the bathroom with her swim suit thrown over her shoulder already going to change.
