The wife’s company had a trip to Mexico for top performers and we got to go one year. It was to one of those all inclusive resorts and we were excited to get away.

When we got there, the first day was fun. She got to meet some coworkers from around the country and we hit it off with one of the guys. He was from the other side of the country from us, single, and about 10 years younger. He was average looking but definitely worked out. I caught my wife staring at him a few times. I saw him staring at her as well when we were all lounging by the pool.

The second day we were will into our drinks and I switched to non-alcoholic beverages once I got a good buzz. My wife kept drinking and was quite intoxicated, to the point where I knew she was going to be out soon. Our new friend was drinking with us and when I knew it was time to get her to the room before she passed out I asked our friend to help. I told him I didn’t think I could manage her on my own.

He agreed and we headed to the elevators. I got a sneaky idea on the way and discreetly worked the tie on the side of her bikini bottom until it was about to fall off. When we got the the room I handed her off to him and opened the door. I then "stumbled" to one of the two beds and acted like I was passing out.

I heard the door shut behind me and could tell he was moving her to the other bed, as I was across the other one with no room. It was dark in the room, with some light coming through the window, and the other bed was visible to me but I was mostly shaded from them. I had my eyes cracked to watch what would happen.

When he put her on the bed her bottoms, as I’d hoped, fell open. He started, backing away and looking to me. I didn’t move or make a sound. He made a move to check me and I closed my eyes, pretending to be out. After a few seconds I could hear him back over at the bed and I cracked my eyes again. He had pulled her bottoms off and slightly spread her legs and was just looking. I could see a bulge developing in his trunks and after a second he moved to pull them down.

His cock popped out and it was pretty big, bigger than mine at least. He moved over and I could see him run a finger back and forth across her slit and then it looked like he slipped it inside. Then he pulled her closer to the edge of the bed and I could see him working the head of his cock back and forth.

She must have gotten wet because after a minute he positioned himself and then eased into her. He stopped, very still to see if she’d react. She moaned lightly, but was otherwise out. He began to move slowly in and out of her, picking up the pace slowly, and after a few minutes I saw him thrust quickly into her and grunt.

He pulled out, wiped his cock with her bottoms, and pulled on his trunks and left. I was immediately up and on her. The show had gotten me hard as a rock and I was about to burst. He must have been quite a bit thicker than me because she was amazingly loose. I came almost instantly and then got us both in bed for the night.

The next morning she had one hell of a hangover but otherwise seemed to have no idea what had happened. We saw her coworker a few more times throughout the trip but he never let on that anything had happened.
