Incest with my stepdaughter

Welcome to this forum and thanks for posting - sex with a child by marriage is still incest even though it's not blood-related - if anything, it's actually a more acceptable form of incest because there's no risk of pregnancy complications that do happen with blood relatives (if that's even the kind of sex you're having). I think there are some fetishists here who would like more details, like how old she is and what kind of sex you're having - but I want to be a supportive voice for you and say that family sex is healthy and natural, as long as the sex is consensual (and I hope it is - it's okay if it's not, but it's certainly more complicated) so I encourage you to explore your sexual desires with your daughter-in-law and to be a positive sexual role model for her as much as you can

Good for you two

Does your wife know?

Is she underage?

not true incest, but many will frown on it. life happens
