Thanks for your feedback. I included MC's face to add more depth to the experience. MNF was the main inspiration for this. That's why the story's similar. There will be interactions between the girls later on while MC's busy. Haven't planned much after that at this point, but I will take your advice and keep it in mind. I'm personally not a big fan of watersports (golden showers), but I reckon I'll be able to include some form of female ejaculation at some point.
As far as Marion is concerned, the reason for her generosity is due to a connection she has between her & Susan that both Susan & MC haven't discovered yet. More to come on that.
Once again, thank you for your support. Cheers.
