You hug your sister, pressing your soft breasts against hers. You feel the warmth of her naked body, it feels so good, you start to understand why, in this reality, siblings don't feel the need to wear clothes when they are together.
Your sister smiles and says: "You've always been there for me. I love you Kate !"
"I love you too !", you say, avoiding to say her name as you don't know it.
You clear your mind, trying to guess at least the name of your herm-sister in this reality. Suddently, you experience like a mental flash, and you know her name: she is Bethany Jane Waters, your little sister. You remember her since the day she was born. She is your baby sister, 10 years younger than you. She is so sweet and innocent, and she considers you as a role model and almost as her third mother. You gave her her first bra, you help her when she had her first period. She talks with you about her crushes, her love life, the ups and downs of her life. You love her, and she loves you. You often cuddle naked in your bed (that's not a big deal in this world), and she is quite jealous of your hermfriends - except, of course, your current hermfriend Jessica.
There is another mental flash, as your mind begins to remember everything about Jessica Peterson, aka Cocky Hardwood. She is a fellow porn actress and she has famously one of the biggest dick in the world - 20 inches long. She is both your hermfriend and a solid partner in the porn movies industry. Jessica and you are porn celebrities - and quite rich. You are also very happy together, end the only reason why you two are not married is because it would be bad for your carreers - married porn actresses sell less on average.
But there is a price to this knowledge: the mental flashes do not give you additional knowledge, they replace the things you knew about your old reality by their counterparts in this new reality. You now think that Bethany has always been your herm sister, you cannot imagine she could have been a boy or a girl in your old reality. Same thing for your hermfriend. Since you still remember that you were an heterosexual male in the old reality, you guess Jessica must have been a girl in the old reality, but you cannot picture her without thinking about her big fat cock always hungry for your pussy.
You wonder what your parents in the old reality would think about their son being fucked by a herm porn star, and there is another mental flash. Your parents have always been two herm women, so of course they do approve your relationship with Jessica. It's even impossible to imagine that your mothers, Patricia and Sylvia, could have been a heterosexual couple in another reality. Was Patricia a man named Patrick ? That's ridiculous, Patricia gave birth to you, while Sylvia gave birth to Bethany, and in the old reality, they would be both considered as very feminine. Maybe they were lesbian women ? But two lesbian women cannot have a son, unless they adopt one, or ...
Maybe, if you focus on yourself, you can solve this mistery. But you understand that when you focus your thoughts on something, you experiment one of those memory-swapping mental flashes, so ...
