My wife always insisted on having a lover’s cock buried to the balls in her pussy when he ejaculated so that most of his cum could be retained to savor for a long period of time after he withdrew. However, she often commented about a certain lover's cum load that was unusually thick and abundant and she could retain a lot of it because his semen clung like glue to her vaginal flesh.. She said, "I could always count on having his cum in me for hours because it just wouldn't purge naturally".
