What Happened on the Water Slides with My Girlfriend’s Friends

My name is Mateo, and that summer I still thought the plan was going to be a bore. My girlfriend, Carolina, had been insisting for weeks that we go to the water park with her two friends and their partners. I had no interest in spending the day standing in line amid children’s screams and the smell of chlorine, but she won me over by arguing that we were going as a group, that everybody would be there, and that I couldn’t always be the boyfriend who stayed home.

—Everybody’s going to be there —she told me—. Don’t make me look bad.

I agreed more for her than because I wanted to. What we didn’t know was that, in the end, her friends’ boyfriends dropped out of the plan one by one: work, a wedding, just not being in the mood. So I ended up being the only man on a trip with three women.

Carolina is a brunette, five foot six, with a little meat where it should be and an ass that has always driven me crazy. Her friend Lucía was the smallest of the three, slim, with a sweet little-girl face that contrasted with a perky ass that seemed not to belong to that body. And then there was Daniela: neither thin nor fat, with just the right curves, an ass that mesmerized and breasts it was hard not to look at every time she bent over.

I admit I’ve always gotten hot fantasizing about my partner’s friends. It’s something I’d never confess out loud, but there I was, walking behind the three of them, letting them get a little ahead so I could stare at their thong-clad asses without being noticed. Who was going to tell me that the day that looked the most boring would turn into the best of the summer.

We started with the big slides, the ones with the double mat. The arrangement was always the same: I went down with Carolina on one and Lucía with Daniela on the other. Until we got to an attraction where the four of us could fit on the same mat, and that was when the first moment of the day happened.

Halfway down, with the momentum of a turn, Daniela’s breast slipped out of her swimsuit. She covered it right away, but I was left staring long enough for her to notice. She blushed, laughed, and when we got to the bottom we all turned it into a joke. No one made a big deal of it. No one except me, who couldn’t get that dark aureole outlined against her lighter skin out of my head.

For the rest of the morning I tried to play it cool, but every time Daniela bent to adjust her swimsuit or pushed the wet hair out of her face, I lost track of whatever Carolina was saying. I felt guilty and turned on in equal measure, that uncomfortable mix that makes you look at what you shouldn’t and hope nobody catches you.

The next ride was for two. Carolina, without thinking, decided to go with Lucía, and I had no choice but to get on with Daniela. Not that I was going to complain.

We climbed the steps in line, and while we waited our turn I noticed she was glancing at me out of the corner of her eye, biting her lip. I thought I was imagining it. We launched ourselves off. The mat was narrow and our bodies pressed together, and then, halfway down, I felt her foot slide between my legs.

It wasn’t an accidental brush. It was a slow, deliberate movement, massaging me over my swimsuit. I looked at her, searching for an explanation, and found her with half-closed eyes and that smile that was no longer innocent in the slightest. My body responded immediately, and because of the pressure the tip popped out above the fabric. She noticed, opened her eyes a little, surprised, and instead of pulling back she started stroking my skin directly with the sole of her foot.

The ride ended too soon. I barely had time to get myself together before the mat stopped in the water. As we got up, she leaned in close to my ear.

—We’re even now —she whispered—. We’ve both enjoyed ourselves.

—More you than me —I replied softly—. I haven’t been able to touch what I saw earlier.

Daniela snorted a laugh and, before going back to the group, dropped a line that kept me tense for the rest of the morning.

—Relax. The day’s long.

From then on I couldn’t think about anything else. I kept mentally going over every possible way to take advantage of how hot Daniela seemed to be, while I pretended to care about the towels, the sun, and Carolina’s conversation.

Near noon we decided to eat. Carolina offered to claim a table by the wave pool, farther away but shaded and quiet. Lucía, Daniela, and I would go to the restaurant to get the food.

On the way, Lucía said she needed to use the restroom. We walked her there and waited outside. That was when Daniela, without saying a word, slipped between two palm trees that hid her from the little foot traffic there was and beckoned me with a finger.

I looked left and right. The palm-lined corridor was almost empty, with the restaurant buzzing a few meters away and people too busy with their trays to notice two bodies pressed together in the shade. My heart was hammering in my chest with a mix of panic and desire I hadn’t felt in years.

I didn’t think twice. The second I got to her side, I grabbed her ass and kissed her with a hunger I hadn’t felt in years. She slid her hand inside my swimsuit and, while she felt me harden, knelt down, pulled the fabric to my thighs, and started running her tongue over me from bottom to top, unhurriedly, looking at me the whole time with a face that had nothing in common with the shy girl at breakfast.

—Do you think we’re even now? —she asked, pulling back for a moment.

—As far as I’m concerned, we never will be —I answered—. I want to keep enjoying a woman like you.

In answer, she took me all the way back in again. I couldn’t stand not touching her any longer, so I lifted her for a second, slipped one strap of her swimsuit down, and pulled out one of those breasts I’d been imagining all morning. I went straight for the nipple while she stroked me.

—I can see you really liked seeing it earlier —she murmured.

We were so caught up in what we were doing that neither of us realized Lucía had come out of the bathroom. Not finding us, she had followed the trail: Daniela’s swimsuit was a bright color that stood out a mile away among the palm trees.

When I saw her appear I froze. I was expecting a scene, an argument, anything but what she said.

—Again, Daniela —she said, arms crossed and half a smile—. Weren’t you satisfied with my boyfriend that now you’re going after Mateo too? I gave you permission, but I don’t think Carolina would be too happy lending out hers.

I couldn’t believe what I was hearing. Daniela, on the other hand, didn’t even flinch.

—She doesn’t need to find out about this —she said calmly—. We’ll figure out how to convince her next time. Don’t you want to join in for a moment and enjoy this?

And she took me by the hand, offering me up almost like a gift. I jolted. Not five seconds had passed when Lucía, that very same Lucía with the sweet little-girl face that had turned me on so much all morning, knelt beside her and took me into her mouth.

Meanwhile she pulled out her two small breasts, perfect for her size, with pink, hard nipples. Daniela knelt too and busied herself lower down, and between the two of them they took turns with a coordination that made it feel like this was not the first time they’d shared something like this.

I braced my back against the rough trunk of the palm tree and closed my eyes for a second, unable to process where I was or how I’d ended up there. The sound of the park kept echoing in the distance, mixed with their breathing and my own pulse. This can’t be happening, I thought, and when I opened my eyes I saw that it was happening, and that none of the three of us had the slightest intention of stopping.

—Let’s leave it here —Daniela said after a while, pulling away, breathing hard—. If we take much longer, Carolina will get suspicious. But the afternoon is going to be a lot more interesting. I’m sure we can figure out how to convince her.

We straightened our swimsuits as best we could and headed to the restaurant, trying to look normal. Lucía walked beside me, and after a bit she leaned in close to speak softly.

—I can’t wait to feel you for real —she told me.

I was surprised those words came from her, the one who seemed the most reserved of the three.

—Neither can I —I replied—. And believe me, I plan to take my time with you.

She laughed, and for the first time it was a laugh with nothing innocent about it.

The four of us ate in the shade, next to the wave pool, while Carolina told us who knows what about a new slide. I nodded, smiled, ran a hand over her back like any attentive boyfriend, and across the table Daniela and Lucía shot me looks that only the three of us understood.

I still couldn’t believe what had happened in just a few hours. I had no words for how lucky I’d been, or for the luck that was still to come if we really managed to convince Carolina. Two of the women I’d fantasized about in secret so many times, now accomplices in a game that had only just begun.

While we were clearing the plates, Daniela brushed against me as she passed and left me one last line in my ear, low enough that nobody else could hear it.

—The afternoon —she said— has just begun.
