Jason is a smart, handsome high school kid, but when he falls hard for Beth, he just can't drum up enough confidence to bring their close friendship to the next level. Meanwhile he has to watch her date other guys. At the end of the summer before college, Jason finally discovers Beth's secret: she is sexually voracious. He also makes an uncomfortable discovery about himself: he is too poorly endowed to ever satisfy a woman like Beth. But wait ... watching her make it with other men is no small turn-on. College brings more brutal lessons in humility, and Jason despairs of finding his place in the sexual universe. Then, as he begins his adult life, he meets Kristen and for the first time begins to take his extracurricular studies in submission seriously. Under Kristen's cruel and compassionate tutelage, he learns exactly what it means to embrace his true cuckold nature.
