While reading casually in bed I start to struggle a little with my breath, my chest gets tight and I cough. As I continue to read it worsens and eventually I am compelled to reach for a mask and ambu bag to help me to refocus on my breathing and to take nice deep breaths. I take these breaths and find myself becoming aroused, I touch myself through my clothes. I then strap on my oxygen mask and use it to help facilitate my breathing while I continue to touch myself. I reach for my hitachi and bring myself to orgasm. Once satisfied I return to reading and continue wearing the oxygen mask.
