Unknown Story Request

I'm looking for an older story that I cant remeber the title to. Multiple part story.

Synopsis: Woman with A.I. spaceship locates and collects bounties on derelict spaceships adrift in space. Locates one and explores, when she discovers skeltal remains clutching a still alive egg. Retrieves egg and goes back to ship, for unknown reason masturbates on egg and it fuses to her then absorbs into her. She passes out for a time and when she wakes up she has given birth to a symbiotic creature who has taken over her ship and melded with her lesbianic A.I.. Ship tells her that ther is a race of futa type lizard creatures forcibly infecting and destroying cultures where-ever they go.

Part 2: A genetically engineered furry futa is treated harshly on a space station. One day its attacked and she is able to save at least one person, one who treated her the worst, from being fully turned by invading lizard futa.

This is all I can remember, it may not be accurate as it has been a while since I read it. Any help would be greatly appreciated.
