Stranger in the Sauna

Got up early last Wednesday morning to go to the gym. It opens at 5:30 am and is close to home so i can ride my mobility scooter there. It is still dark at that time so dressing scantily is not an issue. I wear these oversized cottony boxer shorts and white sleeveless teeshirt which both help to increase my state of arousal. Also popping one little blue pill ensures that when the time is right, my penis will respond to a call for action.
And so I set out on my journey and arrive about thirty minutes later. The pill has done its magic by this time and my erection has slipped out of my loose shorts so I have to cover my lap with a large towel. I drive through the door stopping at the desk to check in and then on to the men’s locker room. All the while the towel covering my increasingly growing hard on, on one hand fearing exposure but the other delighting with the thought of the towel slipping and being exposed!
Upon entering the mens locker room i immediately go to the shower remove my clothes exposing my erect cock and shower. When i am finished I take out my helix, lube it up and insert it in my anus! Then I hop on my cart and drive to the sauna in the next room. No one is there so I go into the sauna with my large towel in tow ready in case I need to cover up.
Sitting there I begin to sweat and start to move my hips naturally as my helix relentlessly hits my prostate. After a while i can feel precum oozing out. Just as I start to reach a heightened state of arousal, I hear the door to the room the sauna is in open up and I have to cover up. Then the door of the sauna opens up and in steps a young guy in his twenties. So now what do I do?
The young man strikes up a conversation with me. He seems very friendly and we talk with each other easily! As we talk about insignificant things I find it increasingly difficult to focus because my helix keeps pushing against my prostate causing me to become increasingly aroused. He looks at me and says, are you ok, you look as if you are about to explode. I told him I was fine, knowing that I wasn’t! I wanted to rip off the towel and orgasm right in front of him!
What happened next I could not have predicted, but it did! He said, are you sure you are ok? I said to him I am great but I cannot hold off anymore! I confessed to him that I had a prostate simulator inserted in my anus and it was causing me extreme pleasure and that I was at the point of exploding. Without saying another word he reached over to me and pulled off my towel exposing my sweaty, aroused, nude body, and my extremely hard erect cock bulging at the seems.
He said to me to go ahead and orgasm and that he would listen and watch and stand guard for me while I did. I didn’t need for him to ask again and so with his blessing I hopped up on the top bench seat, lay down and began to squeeze my butt cheeks together my body contorting as i tried to orgasm.
I could feel precum flowing as I slowly drifted into a complete state of helplessness virtually placing myself in his hands! My connection to reality was gone by now. I felt his hand on my forehead and heard him whisper to me cum. Shaking uncontrollably now I thrust my pelvic area upwards as my erect cock squirted my cum over and over again towards the ceiling and all over my belly!
I heard him say wow many times as I tried to calm down and regain my composure. After about ten minutes he helped me down and I got up and managed to walk to the shower. I showered for what seemed forever in cool water. When i was done I slowly walked back to the shower to thank him but he was gone!
