Is it normal that i love my step-sister?

Seems you found a loophole. This is not incest because she is not blood-related to you.

This is the beginning of almost every pornhub video

🎵I like big butts and I cannot lie; you other brothers can't deny...🎵

The bullsh*t is strong with this one.

While it seems like she is interested; she is still your Step Sister. Technically this potentially is not incest. However, I suggest that you be extra careful not to damage a good brother step-sister family relationship.

Thus, I would suggest that you be extra careful if you progress that she is specifically interested in each progression. I recommend that you specifically ask her what she wants to do or will allow (this may be experimentation on her part and she may not be thinking of full sex).

Do not go beyond the limits she sets. Trust is a big part of a family. You don't want to violate that trust.

Also, if she wants to progress; you need to have a conversation about birth control and STD's before both of you underwear is off... That discussion needs to include what happens if you do get her pregnant. Seriously.

My personal opinion is that too many ladies and men feel that pregnancy will not occur because of birth control or other factors. All methods have their failure rates. You should really ask how will it affect things and what will you do if or when there is a pregnancy. Then I suggest that the two of you think about that for a few days...

A rule I personally adopted decades ago is that I will not have intercourse unless I've decided that the lady is the kind of person I would be OK with having my child with (a good mother, able to care for the child - with my help, no anticipated major family issues, etc.

Another thing I do: is that when I have this conversation - I don't ask them "if..." I ask something like: "OK what are the effects and what are we going to do when I get you pregnant?" That focuses the attention on the question. In the end, only those that admit and accept the possibility, and we come up with a plan/options should birth control fail (or not be used) do I progress with.

Perhaps your time would be better spent writing pseudo-incestuous erotica somewhere belief isn't required.
