With my balls tied I was wondering how to pass the time. Looked arround and found a plastic bag in wich my head fitted. Took my belt, spanked my balls a couple of times and then put the bag arround my head before surrounding my neck with the belt. When the air flow was closed I started to gently slap my balls with my open hand (I don't have much training in hurting my balls). As I breath, the plastic bag contracts and expands making me hear mainly the sound of the bag and on the background was the sound of my balls being slapped. 
The oxigen starts to running out and the bag contracts more and more, I feel it sticking to my face as I try to breath. Countinued slapping my little tied balls with more entusiasm, I feel the pain running through my pelvis but I focus on the lack of oxigen and the pain kind of passes to second place. When the need of air made me start kicking I felt like I was cuming from slpaing my balls but then I remembered that I'm on denial so stoped the slaps and kept strugling to breath.
My breathing, at that point, was so fast and I started to feel my lips kind of tingly. In my desperation I took off the belt but grabed the bag with my hands so I cuold keep fading away. I was kicking and twitching but I just lasted a few seconds more. When I took the bag from my head I was slithly shaking and feeling so fucking horny.
