Decadent Smut: Christina's Torment, 1979

AN EROTIC ODYSSEY INTO THE PERILS OF PASSION: Tauntingly beautiful, achingly desirable, the wealthy Christina van Bell is lavishly seduced--and then kidnapped by a cult of sexual psychopaths. As the ransom negotiations drag on, her life turns into an eternity of lust, passion, and orgies. And what the outcome will be, nobody knows. But for Christina, the waiting is sheer pleasure.
