Hell Comes to Frogtown

‘Hell’ is the identify of the hero of the story. He is a prisoner of the ladies who now run the USA after a nuclear/organic battle. Outcomes of the battle are that mutants have advanced, and the human race is in peril of extinction due to infertility. Hell is given the duty of serving to within the rescue of a gaggle of fertile ladies from the harem of the mutant chief (resembling a frog). Hell can not escape since he has a bomb hooked up to his personal components which can detonate if he strays various hundred yards from his guard.
