Really only when I'm engaged in prostate stimulation while lying on my back. After about 45-60 minutes of constant hands-free dry orgasms I'm usually fever pitch screaming level inside to ejaculate. Its really the most wonderful delicious feeling, the anticipation of full release after not touching my cock for so long yet having Os the whole time. I usually shoot really fucking hard on my chest and stomach, but sometimes on my neck and face occasionally my mouth if its open from yelling or gasping. Normally I'm fucking a fleshlight in a dock and I pull out and shoot wherever it wants to go I love to watch it fly free for several feet. My wife gives me handjobs and I'm on my back and I usually cum all over her hands and on my stomach.
