Lust

A scientist is sequestered in his villa trying (for reasons that eluded me) to splice together the genes of a snake and himself. His neglected (Marina Hedman) meanwhile takes every opportunity to cuckold him with the studly butler. Meanwhile the scientist's adolescent daughter (Cinzia DiCarolis) returns from convent school. Her sex-crazed step-mother hits on her, but the girl instead becomes quite enamored with her father's genetically modified snake after it protects her TWICE from being raped.
