Emma wants you to impregnate her other friends

Over the next couple weeks you continue to fuck Susan regularly, almost always injecting her with a thick load of your jizz, which your girlfriend promptly sucks out of Susan's cunt.

Along the way, Susan finally got around to getting a pregnancy test - confirming what her body had already told her. She's pregnant and nobody but you could be the father. This just made the sex more exciting for everyone. She's even taken to calling you daddy while you fuck her.

Susan feels like she's living a double life - her same mundane life with her boyfriend who is kept happy with a little anal sex - and then her secret life with you and Emma. She takes comfort with knowing that not everyone needs to live a conventional life.

Emma's sexual pleasure is now entirely built upon watching you fuck Susan. She tells pleasure in knowing that she helped inspire the initial insemination because it happened while she was fucking two guys in front of you. But Emma tells you she wants more.

"I want to see you fuck all of my friends. I want you to make them all yours - to take their bodies, use them, inseminate them. I want you to make all my friends pregnant sluts, John," Emma tells you one day while you're fucking Susan in front of her.

Susan doesn't seem happy about sharing you - not like Emma, but she still cums twice - once on your cock and again on Emma's mouth, so she didn't have the energy to argue.
