I really enjoyed VeryWellAged's "Jake" stories, which center on American men traveling to the Philippines and having sex with young women, so I wrote my own long story set in the same universe. The VeryWellAged author reviewed drafts of the story and made suggestions.
Miss Amanda Jones knows what she needs and how to get it. This story pushes the limits of physics, but isn't strictly science fiction. Temporarily suspend whatever you know about physics, and just accept the possibility.
A story in the "Jennifer, Sex Governess" Universe
An Internet ad leads 22-year-old Jen to an unusual family and a job as sex governess for four teens when she isn't submitting sexually to their parents. The college-age pedophile corrupts a young girl and three boys while her limits are tested by parents who apparently have none. Not a stereotypical D/S story, it's about control and dominance of other people's sex lives, often in kinky scenarios with underage (14+) incest. Story codes include mm because boys should be versatile.
Deserted by his wife and left alone with his 15-year-old daughter, Jason soon begins to turn his attention to young Megan, which leads to voyeurism, then to masturbation, and finally, to the inevitable.
A Master's Project Story Todd didn't know he was a voyeur, and Lizzie didn't know she was an exhibitionist. Neither of them knew they'd be attracted to their own daughter. Then Bob interviewed them for his project and everything changed.
It didn't take long after I first had sex with my dad my mom joined us. Imagine my surprise to find out she was an incest daughter as well! Her first experience had been a lot different so she wanted to be sure I things were better for me. Now that everything worked out it was time for me to learn what she had kept hidden from me all these years. I had never really given any thought as to how having sex with your mom would be different than being with your dad - beyond the obvious.
