My family has myself(21), my sister(19), my mom(42), and dad (44). ours is a very sexually open family. sex and nudity was never a taboo subject in my house. we r allowed roam around in the nude, even my parents do the same. there is no restriction to watch or read porn for me and my sister. we can do it in the drawing room in front of our parents. we r allowed to talk or joke about any taboo topics openly. 10 months i had penetrative sex with my sister using a condom. we din feel like hiding it from our parents. when they learnt about it, they werent mad about it. they jus asked us to always use a condom. after that we hav sex frequently. few months ago i started doing my mom too, and my sis with my dad. we are a very normal family outside. both me and my sister are good at studies. am i doing anything wrong??? wat do u guys feel about our lives.
