My girlfriend Laura and I recently took a vacation to Colombia. We stayed in a couple spots but our favorite was on the Caribbean coast. Laura mentioned how she found the men sexy because of the combination of being black and spanish. We've done some group stuff and sharing, so I wondered if we'd have any experiences on the trip.

Toward the end of the visit, we did a day trip that included some tubing and then a walk to a waterfall. We picked a guide named Jose, he was young and handsome, muscular but in a skinny and lean way, more ripped than jacked.

I speak better Spanish than Laura so I was translator. At the waterfall Laura took off a cover to be in her bikini and we swam. There were a few other small groups and Jose stood talking to their guides. Soon all the guides started to mess around, diving off of some rocks and doing flips and stuff. When we had been walking Jose was in jeans, but he took them off and was jumping around in his underwear.

Laura pointed out to me that his bulge looked pretty big. His underwear wasn't leaving much to the imagination as it got wet and clung to his dick. I joked with her that of course she liked it and asked if she'd want to try it, and she laughed and said "I wish."

As it was getting a bit dark, everyone started getting out of the pool and drying off. We asked Jose to take our picture with the waterfall. He took a few, then came over and asked if they were okay. Pointing at the photo he said "Your wife looks beautiful." I took this as my chance and said "she was looking at you too." He thought I was joking, but I went a bit further and said "she's been distracted since you took off your pants" and looked down at this bulge. He started to apologize, still not sure what I meant, but I continued that she wants to see more and I'm okay with it. It took a little bit more discussion to prove I was serious, before he said "okay, let's go behind the waterfall when they all leave" pointing to the last group left with us.

I quickly told Laura and she immediately made her way across the rocky path to behind the waterfall. I went with her, and a few minutes later Jose came. He asked me to look out for others. I did that, splitting my attention between what they were doing and watching for intruders.

Without much fuss, he pulled out his sizeable and completely shaven uncut cock. Laura tried complimenting him in her broken spanish just saying "grande" and starting stroking it. He took one of her boobs out of the bikini top and played with her nipple. She then got on her knees and started to suck it as he got hard. I always love seeing Laura with new guys in spontaneous situations and I was turned on, thinking I should get a turn too, but after maybe only 5 minutes back there, I annoyingly saw a new group walking towards us. I told them and Jose quickly pulled up his underwear and Laura stood up.

I hoped we would just wait it out, but Jose said we should go. I thought he'd wait til his cock softened, but he just walked right out with his huge hard on barely covered. One of the other tourists saw it as he went by, they whispered to their friend and I wondered if they suspected us.

As we walked the 30 minutes or so back to the parking, Jose and I spoke. I told him he should come to our hotel tonight to finish, but he said the security wouldn't let him in and he could lose his guide permit. Instead he said the best is if we go on a boat the next day. He said he can arrange it because his friend has a tourist boat and knows a quiet cove. He also said "this friend also has very big penis, your wife will like to see it".

I wasn't sure if Laura would be down for that, but I got his number to message him. We said a normal professional goodbye, and that night Laura and I fucked 2x, being so turned on by it, trying to decide if we'll say yes to the next day or not.
