Amazons To The Rescue — Susan Hart

Big Amazons To The Rescue, is an offbeat story about a woman who is killed by her abusive husband and finds herself wandering around limbo for a while until she encounters a group of Amazon women and because she has superpowers she can hear what they are doing behind stone walls. After showing her a large coliseum with thousands of men literally rooted to their seats, she learns that the only way these men can achieve a sort of freedom is to bring the Amazon princess to orgasm, but, under her terms. Glynnis spots her husband amongst the vast sea of human males and wonders what's in store for both him, and her own future.
