Last night I went to the pool late and ended up having a threesome in the showers. Usually I go to the pool during the day. It feels warmer, I get some work on my speedo tan and in the middle of the day the pool is generally quiet. Yesterday (Friday) I was busy with work all day and time just got away from me. The pool closes at 9pm and just before 8pm I decided to go for a late night swim. I really wanted to get out of the house and had nothing else planned. The pool was quiet at that hour. I banged out a 2km swim and felt great for making the effort. I jumped out of the pool and started drying off. Usually I just towel down and throw shorts over my speedos and go home. Little bit of a wet bum but it dries out pretty quickly. I've only used the showers/locker room once when I had a meeting after my swim and needed a shower. There I was drying off and I noticed out the corner of my eye one of the lifeguard and a fellow swimming going in to the locker rooms. The lifeguard was in his yellow and red lifeguard shorts and shirt, the swimmer was wearing black speedos and had his towel over his shoulder. Both guys mid to late twenties. It got my attention and I thought I'd go and see if there was anything going on in there. The change rooms are pretty big. The first room I walked in to was a place for people to get changed. It had bench chairs around the walls and some lockers. On one of the chairs was the lifeguards uniform and the towel that the swimmer was carrying. Now I was getting excited. I dropped my gear on one of the chairs. I was wearing a pair of red speedos and nothing else. I walked in to the shower area. It is a big space as well. One wall is open with maybe 8 or 10 shower nozzles on the wall. The opposite site has cubicle with showers for more privacy. I couldn't see anyone but I could hear the shower at the very end in the cubicles running. That must be where these two guys were. I walked down to the last shower nozzle and turned it on. I turned around and had a view in to the last cubicle. There was the lifeguard on his knees sucking off the swimmer. To be honest, they had stopped because I had surprised them but I smiles, gave them nod of approval and started rubbing my cock through the red lycra material of my speedo. The lifeguard was also wearing a red speedo. His hand was down the front of it jerking his cock while his mouth worked the swimmers cock. It was a beautiful sight.
My cock had stiffened and with the water of the shower cascading over me I undid the drawstring on my speedo and released my cock. Tucking the speedo under my balls I started stroking my cock slowly while I soaked in the view of the two young guys. The swimmer waved me over, inviting me to join them in the shower cubical. As I stood next to the swimmer he started stroking my cock. My left hand slid down the back of his black speedo and started playing/fingering his butthole. We started making out. It wasn't long until he started moaning and then we broke off our kiss and he let out the all familiar moans of orgasm. The life guard didn't miss a drop and kept his lips wrapped around his cock. Once he had gotten every last drop, the life guard moved his lips from one cock to mine. Now that the swimmer had free hands he repeated what I had done to him and slipped his hand down the back of my speedo and started fingering me. It was too much, I started cumming. The lifeguard swallowed it all. I figured it was my turn to service the lifeguard and started to get on my knees but the swimmer stopped me. He told me that they were going home and the swimmer was going to let the lifeguard fuck him. I wasn't invited back for the fucking, but the guys said that they might do the same thing next Friday night. Sounds like I have a date next Friday.
