Step Siblings budding lust. M4F

Hello everyone, I am looking to do a step siblings RP where the two have spent there lives together a d are so close that they often sleep in the same bed. But recently (your character) has found that she is wanting more, that she has begun to lust after him, rather than just the family love she had felt before for him, a carnal love seeps in.

If this peaks your interest please let me know in the comments here, thanks for reading how to hear from you!
