My step sister and I have always been pretty close, we re pretty much the same age and even though I think she s really pretty she s never been into men so there wasn t ever any awkward sexual tension between us like most step siblings nowadays. So when I heard her crying in the other room I did what any decent step brother would do and went to roast her a little until she cheered up lmao ? That idea fell apart almost instantly though cause it seemed pretty serious, her and her girlfriend were fighting and this girl had been over to family functions and everything and she always seemed chill to me but apparently that wasn t the case. My step sis was locked in to the idea of getting back at her. I was happy to help brainstorm because fuck that girl, and but I was not ready for her to hit me with her grand plan to really stick it to her. My lesbian step sis looked me square in the eyes and asked me if I would fuck her and cover her in cum so she could send a truly devastating pic to her
