Blackout drill with a stepsis

I had no idea my stepsister had a secret crush on me up until my parents went on a trip to Europe. We had a blackout in the neighborhood and I was chilling by the fireplace when she came on to me saying she was bored and cold and wanted to warm us both up with a blowjob. Hell yeah, she did! Made me cum right in her mouth and a few days later we hooked up again and I finally fucked her tight unshaved pussy. Damn, sis! We gotta do it again!
