As a follow up from last nights euphorific session. Slept full and strong and had some vivid dreams. Have always had the one about being flexible enough and right body shape to fellate myself (still don't think it'll ever happen in real life) and has some intense dreams of doing that to myself. Other dreams took over time and eventually consciousness brought me to awareness of lying in bed in the dark. I could tell it was close to time to arise by the hint of light on the horizon.
I was immediately aware of my horniness level as well as the morning wood stretching my penis to fullness. Lying on my back when waking usually initiates a hard-on especially with the advent of needing to urinate, I think it helps pressure from the bladder generate the right stimulation; if I lay on my side the feeling subsides as does the erection. I threw off the covers so as to not generate any incidental rubbing.
