Last night I went solo without a tool.
I had my peen tuck between my cheeks and drifted off to sleep. I awoke about two hours later to a raging erection, which I kept pushed down behind my legs.
I began to experience a raucous session of Aless spasming which was intensified mightily with nipple stimulation to the point of a massive dry orgasm.
This was one of my strongest ever, with or without the aneros, and left my head spinning and heart pounding.
