@Fun8, kind of crazy that your post nut clarity hit on that and not, like, anything else in or about the video. Anyway, the sperm would probably be the alien sperm and not his own, since semen is just genetic material when you think about it. Realistically, the likelihood of interspecies compatibility is like, nothing, but since we’re in Porn Fantasy Land and nothing about it is realistic, yes, the baby would be half alien.
Is it still inbreeding if Ben does her in alien form, and if he impregnated her as an alien, would the baby be part-alien? I guess what I'm trying to say is, is it the same semen? Sorry, post nut clarity hit hard.
