A female who chooses to have a child with no father involved by means of one night stands, brief relationships et al.

She chooses her victim carefully, he must be intelligent and attractive. And then when the 'timing is right' bed him and utilise his sperm.

Even if protection is used she will find means of transfering the little swimmers from the rubber to her vag before they die out.
She had that kid to some random guy, she's a sperm bandit.
