I (24M straight) knew I was alone at home all day so I set up some piss play, for myself. I'm pretty much a beginner in of this fetish but I basically discovered everything I like and dislike (drinking for me is a big no, although if you have any idea to make it feel better I listen to everything) and I always like to discover my boundaries. Also, I'm single so I like to get creative with solo plays. I started to drink some water and also drank a bit of cola in the morning, and started holding it. When I felt my bladder is pretty filled up I started to casually jerk of and edge, but very gently, so I don't reach the edge too much time. During it I watched some porn in my room (also I played some 3DXChat, if any girl here like to play together hit me up). I hold pee for pretty much time and chugged a plenty of water, when I felt I was ready I went to the bathroom and sit in the bathtub, put on some piss porn, lubed up my penis very well and started edging. When I reached the edge 2 or 3 times I let myself calm down a bit and prepared for the final scene. I put on my cock sling, and hardened my cock better then ever. Then I kneel down into doggy pose and peed in the bathtub. Since I'm a beginner, it really struggles to make myself pee in unnatural poses, but it feels great. After it I felt there is still pee in my bladder, so in kneeling pose and body up I could release the most of the pee. And now for the main part: after I released everything, still kneeling, I pushed my face in my own piss, covering my face in it, licking it, kissing the piss covered bath floor. My cocksling is still on,my cock os harder then ever, I keep jerking off, the sounds of porn is hitting my ear, and I am lost in my own pee. Jerk off faster, I reach the edge but I don't want to hold it any more and cum. At that moment, I experienced the most amazing shaking orgasm I ever had. Post nut clarity hit me surprisingly well, I cleaned up everything, and behave like nothing happened, but in the other hand I will never forget that feeling.
