Variations of the pregnancy tag would be good
Pregnancy [Ending only]
Pregnancy [egg laying/slime]
Pregnancy [in game mechanic] ETC
It would help people to identify what games they want or do not want to play
Can't remember if I already replied in this thread or not
but Pregnancy is one of my main kinks there is nothing better then completely claiming a woman as your own by planting your seed inside her womb
brother + sister. classic taboo I love it when its big brother little sister
Cousin + Cousin. like B/S but once or twice removed
Uncle + niece. very risky taboo must keep it a secret from mom and dad
Aunt + nephew. I really like this one especially if the aunt never had kids that way you can...
