I ordered this strange underwear to try on. Unlike the usual kind with normal fly, this one has a fabric extension which doesn't allow you to put your dick through unless it's fully hardened. Wanking with it gives sensation as if you are wanking from under your pants, in a nice way. I tried on and could resist the urge to really try squeezing my cum out. I was able to hold my first blow and only a bit of pre-cum oozes out. But finally I burst a nice load!
