You could get married, and your mom would become your step sister. Then you'd get free air time on jerry springer, Yay!
Do it then set a cam up and record it, post it here to get the other 50% of my vote on whether you should have did it or not.
And is HE the blood relation??? If so, you'd not only be "Fucking family", you'd be cheatin' on, and with family
Change a few words and you have pretty much explained every family tragedy of this nature: "Hell yeah, I fucked my sister. I was drunk as fuck, though!"
Uhm no thanks. I like to keep to my age-relatives if u know what I mean. I have a thing for young girls. LOL, not that young, you perv.
I hear banjos somewhere off in the distance.... this question has the Deep South written all over it. But no, that would be weird. What if it doesn't go smoothly? You'd have drama when you're hanging out with yout family and what if she tells your/her family? Then you would be known as the kid who fucked his aunt. That's not a good rep to have.
