According to the Glossary on the Wiki site, ALESS means Aneros Less. or without an Aneros.
Last night I went to bed and I didn’t insert my favourite Progasm toy. For those who are following my progress, I have been sleeping with my Progasm inserted and last week I awoke in the middle of the night and had my first MMO experience.
Well, last night I awoke at about 4am and felt the warm P waves building, I lay there enjoying the experience while they increased and increased in intensity and then into a nice mini dry orgasm. My hard started to pound, my breathing became deep and heavy and it felt like I had cum, but there was nothing more than a dribble of pre-cum. It was shortly followed by another one. They didn’t last very long, probably 30 seconds, but it was very pleasant.
What amazed me was there was no Aneros inside me. And it all happened relatively involuntary. I say relatively, because I now can recognise the little sensations to focus my mind on and they do build when you focus on them.
It is like my body has learnt how to do it now and has taken over – I am just a passenger going along for the ride.
