Phrase: Usually occurs during cuming when a lady does not release her grip on the cock at its base. Cum cannot spurt out into her pussy because her fingers block the flow. She has the pleasure of feeling the cock pulsate in her hand as it struggles to void the jism, but the male orgasm cannot be its most intense. Total orgasmic pleasure is directly related to the unrestricted flow of cum into and through the cock shaft.
My wife gripped me too long the other night. She had bad timing and held the cum in my body just a little too long before it erupted as a I blew a nut and flooded her pussy. I am going to have to work harder on better timing, but she is often a naughty lover and does not concentrate well when cuming. May be I will have to beg louder.
