By the same token, it wouldn't be wrong of your sister to sever her relationship with you. This will happen, and you must be prepared for that.

Oh, yes. It would be very wrong of the sister to sever her relationship with OP. The request is a huge request. It isn't something OP is obligated to do. The sister doesn't have a right to use OP's body to make a baby. That's horribly invasive.

If the sister severed her relationship with OP over this then the sister is a narcissist with poor boundaries. OP is better off without her.

Well, the sister is not obligated to pretend like nothing ever happened. Yes, I agree the request is more than most would consider acceptable. This is exactly why such circumstances negatively affect family dynamics forever. It is the natural progression of things, and no, there is nothing "wrong" about it.

Whether OP is better of without her sister or not is irrelevant.
