Fill her completely with eggs

You are getting ready to start firing your eggs into her when you sense a sudden violent aggressive thought from Jack, he is planning to kill you. You put in his mind that he is unable to move and he should just enjoy watching. This seems to placate him, but you still sense he intends you harm so decide that the vengeance you will have will be to make his daughter into a breeding sow. You tell her that you are gonna cum to get ready. Initially she nods her head then realising what this would mean she starts to speak "nnnn...nno...please pull out im not on anything, unlike mom, you could impregnate me" , you grasp her shoulders and lean down and whisper in her ear, "thats alright... youll be a great mom..." and with that drive yourself hard against her ass and groan, your grip on her shoulders stop her from pushing off of you (although your cervix invading tube would have ripped out her womb if she had managed to pull herself off your cock) Then she feels your cock starting to bulge as the eggs began to get pumped into her womb , "ooooh... nooo....oooh.... so hard... ummmm....please stop....aaarhhhhh" ,you continue pumping eggs in for at least ten minutes her belly looks several months pregnant and her breasts have increased a few cup sizes, likely the amount of eggs increased the hormones needed. She has had one long orgasm whilst you impregnated her and as she comes down she looks down and sees here pendulous heavy breasts and her newly enlarged belly, she looks shocked. "oh my god i look pregnant, how much cum did you put into me, I had no idea that men could put that much cum in a girl, I feel heavy", you smile, safe in the knowledge that she will be having your progeny for many years. At least 50.

You put a thought in Jack's mind and make him fall asleep and forget what he saw and then you put a thought in Jane that she should sleep on the bed with her mother and you go and inject a tracking isotope into both her and her mother so you can find them and know when the babies are due.

Over the next three months both women swell up with his seed and begin birthing a new crew for his ship. Unexpectedly Jane's first pregnancy was twins, she had a great deal of difficulty pushing them out but her mother giving birth next to her helped her.
