Had my first true sissygasm today, I think. Haven't jerked off since Friday before last; anal stimulation only. Slept in chastity all week; couldn't do it during the day, as the device shows through my pants at work and I sweat a fair bit in it, but been sleeping with it on. Woke up around 3am today; spent a couple of hours with my toy collection. Finally, after getting 4 1/2 of the 5 balls of my Master Series Black Baller Large up me and having them up there for a while, pulled them out and sprayed cum about a foot and a half. Did that 2 more times and called that it, but it was seriously incredible and I feel no need for penile stimulation at all. Also, the cum was delicious when I licked it up!

I've cum from being fucked plenty of times in the past, but without penile stimulation it was generally just prostate fluid. This was actual honest to goodness cum. 

Went ahead and ordered a prostate stimulator and some ruffly panties; I think I've crossed the sissy Rubicon.  :)
